    We’ll be testing this simple implementation of an
+integer minimum. Typically, the code we’re testing
+would be in a source file named something like
+intutils.go, and the test file for it would then
+be named intutils_test.go.
    
+
+              		
+            
+          
    func IntMin(a, b int) int {
+    if a < b {
+        return a
+    } else {
+        return b
+    }
+}
+
    
+
+          
    
+            
    A test is created by writing a function with a name
+beginning with Test.
    
+
+              		
+            
+          
    func TestIntMinBasic(t *testing.T) {
+    ans := IntMin(2, -2)
+    if ans != -2 {
+
    
+
+          
    
+            
    t.Error* will report test failures but continue
+executing the test. t.Fail* will report test
+failures and stop the test immediately.
    
+
+              		
+            
+          
            t.Errorf("IntMin(2, -2) = %d; want -2", ans)
+    }
+}
+
    
+
+          
    
+            
    Writing tests can be repetitive, so it’s idiomatic to
+use a table-driven style, where test inputs and
+expected outputs are listed in a table and a single loop
+walks over them and performs the test logic.
    
+
+              		
+            
+          
    func TestIntMinTableDriven(t *testing.T) {
+    var tests = []struct {
+        a, b int
+        want int
+    }{
+        {0, 1, 0},
+        {1, 0, 0},
+        {2, -2, -2},
+        {0, -1, -1},
+        {-1, 0, -1},
+    }
+
    
+
+          
    
+            
    t.Run enables running “subtests”, one for each
+table entry. These are shown separately
+when executing go test -v.
    
+
+              		
+            
+          
        for _, tt := range tests {
+
    
+
+          
    
+            
+          
+            
+          
            testname := fmt.Sprintf("%d,%d", tt.a, tt.b)
+        t.Run(testname, func(t *testing.T) {
+            ans := IntMin(tt.a, tt.b)
+            if ans != tt.want {
+                t.Errorf("got %d, want %d", ans, tt.want)
+            }
+        })
+    }

Subject: [PATCH 065/283] go.mod: add go.mod and move pygments to third_party

After go1.16, go will use module mode by default,
even when the repository is checked out under GOPATH
or in a one-off directory. Add go.mod, go.sum to keep
this repo buildable without opting out of the module
mode.

> go mod init github.com/mmcgrana/gobyexample
> go mod tidy
> go mod vendor

In module mode, the 'vendor' directory is special
and its contents will be actively maintained by the
go command. pygments aren't the dependency the go will
know about, so it will delete the contents from vendor
directory. Move it to `third_party` directory now.

And, vendor the blackfriday package.

Note: the tutorial contents are not affected by the
change in go1.16 because all the examples in this
tutorial ask users to run the go command with the
explicit list of files to be compiled (e.g.
`go run hello-world.go` or `go build command-line-arguments.go`).
When the source list is provided, the go command does
not have to compute the build list and whether it's
running in GOPATH mode or module mode becomes irrelevant.

+Blackfriday
+[![Build Status][BuildV2SVG]][BuildV2URL]
+[![PkgGoDev][PkgGoDevV2SVG]][PkgGoDevV2URL]
+===========
+
+Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
+is paranoid about its input (so you can safely feed it user-supplied
+data), it is fast, it supports common extensions (tables, smart
+punctuation substitutions, etc.), and it is safe for all utf-8
+(unicode) input.
+
+HTML output is currently supported, along with Smartypants
+extensions.
+
+It started as a translation from C of [Sundown][3].
+
+
+Installation
+------------
+
+Blackfriday is compatible with modern Go releases in module mode.
+With Go installed:
+
+    go get github.com/russross/blackfriday
+
+will resolve and add the package to the current development module,
+then build and install it. Alternatively, you can achieve the same
+if you import it in a package:
+
+    import "github.com/russross/blackfriday"
+
+and `go get` without parameters.
+
+Old versions of Go and legacy GOPATH mode might work,
+but no effort is made to keep them working.
+
+
+Versions
+--------
+
+Currently maintained and recommended version of Blackfriday is `v2`. It's being
+developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the
+documentation is available at
+https://pkg.go.dev/github.com/russross/blackfriday/v2.
+
+It is `go get`-able in module mode at `github.com/russross/blackfriday/v2`.
+
+Version 2 offers a number of improvements over v1:
+
+* Cleaned up API
+* A separate call to [`Parse`][4], which produces an abstract syntax tree for
+  the document
+* Latest bug fixes
+* Flexibility to easily add your own rendering extensions
+
+Potential drawbacks:
+
+* Our benchmarks show v2 to be slightly slower than v1. Currently in the
+  ballpark of around 15%.
+* API breakage. If you can't afford modifying your code to adhere to the new API
+  and don't care too much about the new features, v2 is probably not for you.
+* Several bug fixes are trailing behind and still need to be forward-ported to
+  v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for
+  tracking.
+
+If you are still interested in the legacy `v1`, you can import it from
+`github.com/russross/blackfriday`. Documentation for the legacy v1 can be found
+here: https://pkg.go.dev/github.com/russross/blackfriday.
+
+
+Usage
+-----
+
+### v1
+
+For basic usage, it is as simple as getting your input into a byte
+slice and calling:
+
+```go
+output := blackfriday.MarkdownBasic(input)
+```
+
+This renders it with no extensions enabled. To get a more useful
+feature set, use this instead:
+
+```go
+output := blackfriday.MarkdownCommon(input)
+```
+
+### v2
+
+For the most sensible markdown processing, it is as simple as getting your input
+into a byte slice and calling:
+
+```go
+output := blackfriday.Run(input)
+```
+
+Your input will be parsed and the output rendered with a set of most popular
+extensions enabled. If you want the most basic feature set, corresponding with
+the bare Markdown specification, use:
+
+```go
+output := blackfriday.Run(input, blackfriday.WithNoExtensions())
+```
+
+### Sanitize untrusted content
+
+Blackfriday itself does nothing to protect against malicious content. If you are
+dealing with user-supplied markdown, we recommend running Blackfriday's output
+through HTML sanitizer such as [Bluemonday][5].
+
+Here's an example of simple usage of Blackfriday together with Bluemonday:
+
+```go
+import (
+    "github.com/microcosm-cc/bluemonday"
+    "github.com/russross/blackfriday"
+)
+
+// ...
+unsafe := blackfriday.Run(input)
+html := bluemonday.UGCPolicy().SanitizeBytes(unsafe)
+```
+
+### Custom options, v1
+
+If you want to customize the set of options, first get a renderer
+(currently only the HTML output engine), then use it to
+call the more general `Markdown` function. For examples, see the
+implementations of `MarkdownBasic` and `MarkdownCommon` in
+`markdown.go`.
+
+### Custom options, v2
+
+If you want to customize the set of options, use `blackfriday.WithExtensions`,
+`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`.
+
+### `blackfriday-tool`
+
+You can also check out `blackfriday-tool` for a more complete example
+of how to use it. Download and install it using:
+
+    go get github.com/russross/blackfriday-tool
+
+This is a simple command-line tool that allows you to process a
+markdown file using a standalone program.  You can also browse the
+source directly on github if you are just looking for some example
+code:
+
+* 
+
+Note that if you have not already done so, installing
+`blackfriday-tool` will be sufficient to download and install
+blackfriday in addition to the tool itself. The tool binary will be
+installed in `$GOPATH/bin`.  This is a statically-linked binary that
+can be copied to wherever you need it without worrying about
+dependencies and library versions.
+
+### Sanitized anchor names
+
+Blackfriday includes an algorithm for creating sanitized anchor names
+corresponding to a given input text. This algorithm is used to create
+anchors for headings when `EXTENSION_AUTO_HEADER_IDS` is enabled. The
+algorithm has a specification, so that other packages can create
+compatible anchor names and links to those anchors.
+
+The specification is located at https://pkg.go.dev/github.com/russross/blackfriday#hdr-Sanitized_Anchor_Names.
+
+[`SanitizedAnchorName`](https://pkg.go.dev/github.com/russross/blackfriday#SanitizedAnchorName) exposes this functionality, and can be used to
+create compatible links to the anchor names generated by blackfriday.
+This algorithm is also implemented in a small standalone package at
+[`github.com/shurcooL/sanitized_anchor_name`](https://pkg.go.dev/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients
+that want a small package and don't need full functionality of blackfriday.
+
+
+Features
+--------
+
+All features of Sundown are supported, including:
+
+*   **Compatibility**. The Markdown v1.0.3 test suite passes with
+    the `--tidy` option.  Without `--tidy`, the differences are
+    mostly in whitespace and entity escaping, where blackfriday is
+    more consistent and cleaner.
+
+*   **Common extensions**, including table support, fenced code
+    blocks, autolinks, strikethroughs, non-strict emphasis, etc.
+
+*   **Safety**. Blackfriday is paranoid when parsing, making it safe
+    to feed untrusted user input without fear of bad things
+    happening. The test suite stress tests this and there are no
+    known inputs that make it crash.  If you find one, please let me
+    know and send me the input that does it.
+
+    NOTE: "safety" in this context means *runtime safety only*. In order to
+    protect yourself against JavaScript injection in untrusted content, see
+    [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
+
+*   **Fast processing**. It is fast enough to render on-demand in
+    most web applications without having to cache the output.
+
+*   **Thread safety**. You can run multiple parsers in different
+    goroutines without ill effect. There is no dependence on global
+    shared state.
+
+*   **Minimal dependencies**. Blackfriday only depends on standard
+    library packages in Go. The source code is pretty
+    self-contained, so it is easy to add to any project, including
+    Google App Engine projects.
+
+*   **Standards compliant**. Output successfully validates using the
+    W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
+
+
+Extensions
+----------
+
+In addition to the standard markdown syntax, this package
+implements the following extensions:
+
+*   **Intra-word emphasis supression**. The `_` character is
+    commonly used inside words when discussing code, so having
+    markdown interpret it as an emphasis command is usually the
+    wrong thing. Blackfriday lets you treat all emphasis markers as
+    normal characters when they occur inside a word.
+
+*   **Tables**. Tables can be created by drawing them in the input
+    using a simple syntax:
+
+    ```
+    Name    | Age
+    --------|------
+    Bob     | 27
+    Alice   | 23
+    ```
+
+*   **Fenced code blocks**. In addition to the normal 4-space
+    indentation to mark code blocks, you can explicitly mark them
+    and supply a language (to make syntax highlighting simple). Just
+    mark it like this:
+
+        ```go
+        func getTrue() bool {
+            return true
+        }
+        ```
+
+    You can use 3 or more backticks to mark the beginning of the
+    block, and the same number to mark the end of the block.
+
+    To preserve classes of fenced code blocks while using the bluemonday
+    HTML sanitizer, use the following policy:
+
+    ```go
+    p := bluemonday.UGCPolicy()
+    p.AllowAttrs("class").Matching(regexp.MustCompile("^language-[a-zA-Z0-9]+$")).OnElements("code")
+    html := p.SanitizeBytes(unsafe)
+    ```
+
+*   **Definition lists**. A simple definition list is made of a single-line
+    term followed by a colon and the definition for that term.
+
+        Cat
+        : Fluffy animal everyone likes
+
+        Internet
+        : Vector of transmission for pictures of cats
+
+    Terms must be separated from the previous definition by a blank line.
+
+*   **Footnotes**. A marker in the text that will become a superscript number;
+    a footnote definition that will be placed in a list of footnotes at the
+    end of the document. A footnote looks like this:
+
+        This is a footnote.[^1]
+
+        [^1]: the footnote text.
+
+*   **Autolinking**. Blackfriday can find URLs that have not been
+    explicitly marked as links and turn them into links.
+
+*   **Strikethrough**. Use two tildes (`~~`) to mark text that
+    should be crossed out.
+
+*   **Hard line breaks**. With this extension enabled (it is off by
+    default in the `MarkdownBasic` and `MarkdownCommon` convenience
+    functions), newlines in the input translate into line breaks in
+    the output.
+
+*   **Smart quotes**. Smartypants-style punctuation substitution is
+    supported, turning normal double- and single-quote marks into
+    curly quotes, etc.
+
+*   **LaTeX-style dash parsing** is an additional option, where `--`
+    is translated into `–`, and `---` is translated into
+    `—`. This differs from most smartypants processors, which
+    turn a single hyphen into an ndash and a double hyphen into an
+    mdash.
+
+*   **Smart fractions**, where anything that looks like a fraction
+    is translated into suitable HTML (instead of just a few special
+    cases like most smartypant processors). For example, `4/5`
+    becomes `4⁄5`, which renders as
+    4⁄5.
+
+
+Other renderers
+---------------
+
+Blackfriday is structured to allow alternative rendering engines. Here
+are a few of note:
+
+*   [github_flavored_markdown](https://pkg.go.dev/github.com/shurcooL/github_flavored_markdown):
+    provides a GitHub Flavored Markdown renderer with fenced code block
+    highlighting, clickable heading anchor links.
+
+    It's not customizable, and its goal is to produce HTML output
+    equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
+    except the rendering is performed locally.
+
+*   [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
+    but for markdown.
+
+*   [LaTeX output](https://gitlab.com/ambrevar/blackfriday-latex):
+    renders output as LaTeX.
+
+*   [bfchroma](https://github.com/Depado/bfchroma/): provides convenience
+    integration with the [Chroma](https://github.com/alecthomas/chroma) code
+    highlighting library. bfchroma is only compatible with v2 of Blackfriday and
+    provides a drop-in renderer ready to use with Blackfriday, as well as
+    options and means for further customization.
+
+*   [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer.
+
+*   [Blackfriday-Slack](https://github.com/karriereat/blackfriday-slack): converts markdown to slack message style
+
+
+TODO
+----
+
+*   More unit testing
+*   Improve Unicode support. It does not understand all Unicode
+    rules (about what constitutes a letter, a punctuation symbol,
+    etc.), so it may fail to detect word boundaries correctly in
+    some instances. It is safe on all UTF-8 input.

+// Package blackfriday is a Markdown processor.
+//
+// It translates plain text with simple formatting rules into HTML or LaTeX.
+//
+// Sanitized Anchor Names
+//
+// Blackfriday includes an algorithm for creating sanitized anchor names
+// corresponding to a given input text. This algorithm is used to create
+// anchors for headings when EXTENSION_AUTO_HEADER_IDS is enabled. The
+// algorithm is specified below, so that other packages can create
+// compatible anchor names and links to those anchors.
+//
+// The algorithm iterates over the input text, interpreted as UTF-8,
+// one Unicode code point (rune) at a time. All runes that are letters (category L)
+// or numbers (category N) are considered valid characters. They are mapped to
+// lower case, and included in the output. All other runes are considered
+// invalid characters. Invalid characters that preceed the first valid character,
+// as well as invalid character that follow the last valid character
+// are dropped completely. All other sequences of invalid characters
+// between two valid characters are replaced with a single dash character '-'.
+//
+// SanitizedAnchorName exposes this functionality, and can be used to
+// create compatible links to the anchor names generated by blackfriday.
+// This algorithm is also implemented in a small standalone package at
+// github.com/shurcooL/sanitized_anchor_name. It can be useful for clients
+// that want a small package and don't need full functionality of blackfriday.
+package blackfriday
+
+// NOTE: Keep Sanitized Anchor Name algorithm in sync with package
+//       github.com/shurcooL/sanitized_anchor_name.
+//       Otherwise, users of sanitized_anchor_name will get anchor names
+//       that are incompatible with those generated by blackfriday.

-=====================
-The full Pygments API
-=====================
-
-This page describes the Pygments API.
-
-High-level API
-==============
-
-.. module:: pygments
-
-Functions from the :mod:`pygments` module:
-
-.. function:: lex(code, lexer)
-
-    Lex `code` with the `lexer` (must be a `Lexer` instance)
-    and return an iterable of tokens. Currently, this only calls
-    `lexer.get_tokens()`.
-
-.. function:: format(tokens, formatter, outfile=None)
-
-    Format a token stream (iterable of tokens) `tokens` with the
-    `formatter` (must be a `Formatter` instance). The result is
-    written to `outfile`, or if that is ``None``, returned as a
-    string.
-
-.. function:: highlight(code, lexer, formatter, outfile=None)
-
-    This is the most high-level highlighting function.
-    It combines `lex` and `format` in one function.
-
-
-.. module:: pygments.lexers
-
-Functions from :mod:`pygments.lexers`:
-
-.. function:: get_lexer_by_name(alias, **options)
-
-    Return an instance of a `Lexer` subclass that has `alias` in its
-    aliases list. The lexer is given the `options` at its
-    instantiation.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if no lexer with that alias is
-    found.
-
-.. function:: get_lexer_for_filename(fn, **options)
-
-    Return a `Lexer` subclass instance that has a filename pattern
-    matching `fn`. The lexer is given the `options` at its
-    instantiation.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if no lexer for that filename
-    is found.
-
-.. function:: get_lexer_for_mimetype(mime, **options)
-
-    Return a `Lexer` subclass instance that has `mime` in its mimetype
-    list. The lexer is given the `options` at its instantiation.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if not lexer for that mimetype
-    is found.
-
-.. function:: guess_lexer(text, **options)
-
-    Return a `Lexer` subclass instance that's guessed from the text in
-    `text`. For that, the :meth:`.analyse_text()` method of every known lexer
-    class is called with the text as argument, and the lexer which returned the
-    highest value will be instantiated and returned.
-
-    :exc:`pygments.util.ClassNotFound` is raised if no lexer thinks it can
-    handle the content.
-
-.. function:: guess_lexer_for_filename(filename, text, **options)
-
-    As :func:`guess_lexer()`, but only lexers which have a pattern in `filenames`
-    or `alias_filenames` that matches `filename` are taken into consideration.
-
-    :exc:`pygments.util.ClassNotFound` is raised if no lexer thinks it can
-    handle the content.
-
-.. function:: get_all_lexers()
-
-    Return an iterable over all registered lexers, yielding tuples in the
-    format::
-
-    	(longname, tuple of aliases, tuple of filename patterns, tuple of mimetypes)
-
-    .. versionadded:: 0.6
-
-
-.. module:: pygments.formatters
-
-Functions from :mod:`pygments.formatters`:
-
-.. function:: get_formatter_by_name(alias, **options)
-
-    Return an instance of a :class:`.Formatter` subclass that has `alias` in its
-    aliases list. The formatter is given the `options` at its instantiation.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if no formatter with that
-    alias is found.
-
-.. function:: get_formatter_for_filename(fn, **options)
-
-    Return a :class:`.Formatter` subclass instance that has a filename pattern
-    matching `fn`. The formatter is given the `options` at its instantiation.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if no formatter for that filename
-    is found.
-
-
-.. module:: pygments.styles
-
-Functions from :mod:`pygments.styles`:
-
-.. function:: get_style_by_name(name)
-
-    Return a style class by its short name. The names of the builtin styles
-    are listed in :data:`pygments.styles.STYLE_MAP`.
-
-    Will raise :exc:`pygments.util.ClassNotFound` if no style of that name is
-    found.
-
-.. function:: get_all_styles()
-
-    Return an iterable over all registered styles, yielding their names.
-
-    .. versionadded:: 0.6
-
-
-.. module:: pygments.lexer
-
-Lexers
-======
-
-The base lexer class from which all lexers are derived is:
-
-.. class:: Lexer(**options)
-
-    The constructor takes a \*\*keywords dictionary of options.
-    Every subclass must first process its own options and then call
-    the `Lexer` constructor, since it processes the `stripnl`,
-    `stripall` and `tabsize` options.
-
-    An example looks like this:
-
-    .. sourcecode:: python
-
-        def __init__(self, **options):
-            self.compress = options.get('compress', '')
-            Lexer.__init__(self, **options)
-
-    As these options must all be specifiable as strings (due to the
-    command line usage), there are various utility functions
-    available to help with that, see `Option processing`_.
-
-    .. method:: get_tokens(text)
-
-        This method is the basic interface of a lexer. It is called by
-        the `highlight()` function. It must process the text and return an
-        iterable of ``(tokentype, value)`` pairs from `text`.
-
-        Normally, you don't need to override this method. The default
-        implementation processes the `stripnl`, `stripall` and `tabsize`
-        options and then yields all tokens from `get_tokens_unprocessed()`,
-        with the ``index`` dropped.
-
-    .. method:: get_tokens_unprocessed(text)
-
-        This method should process the text and return an iterable of
-        ``(index, tokentype, value)`` tuples where ``index`` is the starting
-        position of the token within the input text.
-
-        This method must be overridden by subclasses.
-
-    .. staticmethod:: analyse_text(text)
-
-        A static method which is called for lexer guessing. It should analyse
-        the text and return a float in the range from ``0.0`` to ``1.0``.
-        If it returns ``0.0``, the lexer will not be selected as the most
-        probable one, if it returns ``1.0``, it will be selected immediately.
-
-        .. note:: You don't have to add ``@staticmethod`` to the definition of
-                  this method, this will be taken care of by the Lexer's metaclass.
-
-    For a list of known tokens have a look at the :doc:`tokens` page.
-
-    A lexer also can have the following attributes (in fact, they are mandatory
-    except `alias_filenames`) that are used by the builtin lookup mechanism.
-
-    .. attribute:: name
-
-        Full name for the lexer, in human-readable form.
-
-    .. attribute:: aliases
-
-        A list of short, unique identifiers that can be used to lookup
-        the lexer from a list, e.g. using `get_lexer_by_name()`.
-
-    .. attribute:: filenames
-
-        A list of `fnmatch` patterns that match filenames which contain
-        content for this lexer. The patterns in this list should be unique among
-        all lexers.
-
-    .. attribute:: alias_filenames
-
-        A list of `fnmatch` patterns that match filenames which may or may not
-        contain content for this lexer. This list is used by the
-        :func:`.guess_lexer_for_filename()` function, to determine which lexers
-        are then included in guessing the correct one. That means that
-        e.g. every lexer for HTML and a template language should include
-        ``\*.html`` in this list.
-
-    .. attribute:: mimetypes
-
-        A list of MIME types for content that can be lexed with this
-        lexer.
-
-
-.. module:: pygments.formatter
-
-Formatters
-==========
-
-A formatter is derived from this class:
-
-
-.. class:: Formatter(**options)
-
-    As with lexers, this constructor processes options and then must call the
-    base class :meth:`__init__`.
-
-    The :class:`Formatter` class recognizes the options `style`, `full` and
-    `title`.  It is up to the formatter class whether it uses them.
-
-    .. method:: get_style_defs(arg='')
-
-        This method must return statements or declarations suitable to define
-        the current style for subsequent highlighted text (e.g. CSS classes
-        in the `HTMLFormatter`).
-
-        The optional argument `arg` can be used to modify the generation and
-        is formatter dependent (it is standardized because it can be given on
-        the command line).
-
-        This method is called by the ``-S`` :doc:`command-line option `,
-        the `arg` is then given by the ``-a`` option.
-
-    .. method:: format(tokensource, outfile)
-
-        This method must format the tokens from the `tokensource` iterable and
-        write the formatted version to the file object `outfile`.
-
-        Formatter options can control how exactly the tokens are converted.
-
-    .. versionadded:: 0.7
-       A formatter must have the following attributes that are used by the
-       builtin lookup mechanism.
-
-    .. attribute:: name
-
-        Full name for the formatter, in human-readable form.
-
-    .. attribute:: aliases
-
-        A list of short, unique identifiers that can be used to lookup
-        the formatter from a list, e.g. using :func:`.get_formatter_by_name()`.
-
-    .. attribute:: filenames
-
-        A list of :mod:`fnmatch` patterns that match filenames for which this
-        formatter can produce output. The patterns in this list should be unique
-        among all formatters.
-
-
-.. module:: pygments.util
-
-Option processing
-=================
-
-The :mod:`pygments.util` module has some utility functions usable for option
-processing:
-
-.. exception:: OptionError
-
-    This exception will be raised by all option processing functions if
-    the type or value of the argument is not correct.
-
-.. function:: get_bool_opt(options, optname, default=None)
-
-    Interpret the key `optname` from the dictionary `options` as a boolean and
-    return it. Return `default` if `optname` is not in `options`.
-
-    The valid string values for ``True`` are ``1``, ``yes``, ``true`` and
-    ``on``, the ones for ``False`` are ``0``, ``no``, ``false`` and ``off``
-    (matched case-insensitively).
-
-.. function:: get_int_opt(options, optname, default=None)
-
-    As :func:`get_bool_opt`, but interpret the value as an integer.
-
-.. function:: get_list_opt(options, optname, default=None)
-
-    If the key `optname` from the dictionary `options` is a string,
-    split it at whitespace and return it. If it is already a list
-    or a tuple, it is returned as a list.
-
-.. function:: get_choice_opt(options, optname, allowed, default=None)
-
-    If the key `optname` from the dictionary is not in the sequence
-    `allowed`, raise an error, otherwise return it.
-
-    .. versionadded:: 0.8

-
-======================
-Command Line Interface
-======================
-
-You can use Pygments from the shell, provided you installed the
-:program:`pygmentize` script::
-
-    $ pygmentize test.py
-    print "Hello World"
-
-will print the file test.py to standard output, using the Python lexer
-(inferred from the file name extension) and the terminal formatter (because
-you didn't give an explicit formatter name).
-
-If you want HTML output::
-
-    $ pygmentize -f html -l python -o test.html test.py
-
-As you can see, the -l option explicitly selects a lexer. As seen above, if you
-give an input file name and it has an extension that Pygments recognizes, you can
-omit this option.
-
-The ``-o`` option gives an output file name. If it is not given, output is
-written to stdout.
-
-The ``-f`` option selects a formatter (as with ``-l``, it can also be omitted
-if an output file name is given and has a supported extension).
-If no output file name is given and ``-f`` is omitted, the
-:class:`.TerminalFormatter` is used.
-
-The above command could therefore also be given as::
-
-    $ pygmentize -o test.html test.py
-
-To create a full HTML document, including line numbers and stylesheet (using the
-"emacs" style), highlighting the Python file ``test.py`` to ``test.html``::
-
-    $ pygmentize -O full,style=emacs -o test.html test.py
-
-
-Options and filters
--------------------
-
-Lexer and formatter options can be given using the ``-O`` option::
-
-    $ pygmentize -f html -O style=colorful,linenos=1 -l python test.py
-
-Be sure to enclose the option string in quotes if it contains any special shell
-characters, such as spaces or expansion wildcards like ``*``. If an option
-expects a list value, separate the list entries with spaces (you'll have to
-quote the option value in this case too, so that the shell doesn't split it).
-
-Since the ``-O`` option argument is split at commas and expects the split values
-to be of the form ``name=value``, you can't give an option value that contains
-commas or equals signs.  Therefore, an option ``-P`` is provided (as of Pygments
-0.9) that works like ``-O`` but can only pass one option per ``-P``. Its value
-can then contain all characters::
-
-    $ pygmentize -P "heading=Pygments, the Python highlighter" ...
-
-Filters are added to the token stream using the ``-F`` option::
-
-    $ pygmentize -f html -l pascal -F keywordcase:case=upper main.pas
-
-As you see, options for the filter are given after a colon. As for ``-O``, the
-filter name and options must be one shell word, so there may not be any spaces
-around the colon.
-
-
-Generating styles
------------------
-
-Formatters normally don't output full style information.  For example, the HTML
-formatter by default only outputs ```` tags with ``class`` attributes.
-Therefore, there's a special ``-S`` option for generating style definitions.
-Usage is as follows::
-
-    $ pygmentize -f html -S colorful -a .syntax
-
-generates a CSS style sheet (because you selected the HTML formatter) for
-the "colorful" style prepending a ".syntax" selector to all style rules.
-
-For an explanation what ``-a`` means for :doc:`a particular formatter
-`, look for the `arg` argument for the formatter's
-:meth:`.get_style_defs()` method.
-
-
-Getting lexer names
--------------------
-
-.. versionadded:: 1.0
-
-The ``-N`` option guesses a lexer name for a given filename, so that ::
-
-    $ pygmentize -N setup.py
-
-will print out ``python``.  It won't highlight anything yet.  If no specific
-lexer is known for that filename, ``text`` is printed.
-
-
-Getting help
-------------
-
-The ``-L`` option lists lexers, formatters, along with their short
-names and supported file name extensions, styles and filters. If you want to see
-only one category, give it as an argument::
-
-    $ pygmentize -L filters
-
-will list only all installed filters.
-
-The ``-H`` option will give you detailed information (the same that can be found
-in this documentation) about a lexer, formatter or filter. Usage is as follows::
-
-    $ pygmentize -H formatter html
-
-will print the help for the HTML formatter, while ::
-
-    $ pygmentize -H lexer python
-
-will print the help for the Python lexer, etc.
-
-
-A note on encodings
--------------------
-
-.. versionadded:: 0.9
-
-Pygments tries to be smart regarding encodings in the formatting process:
-
-* If you give an ``encoding`` option, it will be used as the input and
-  output encoding.
-
-* If you give an ``outencoding`` option, it will override ``encoding``
-  as the output encoding.
-
-* If you give an ``inencoding`` option, it will override ``encoding``
-  as the input encoding.
-
-* If you don't give an encoding and have given an output file, the default
-  encoding for lexer and formatter is the terminal encoding or the default
-  locale encoding of the system.  As a last resort, ``latin1`` is used (which
-  will pass through all non-ASCII characters).
-
-* If you don't give an encoding and haven't given an output file (that means
-  output is written to the console), the default encoding for lexer and
-  formatter is the terminal encoding (``sys.stdout.encoding``).

-=====================
-Write your own filter
-=====================
-
-.. versionadded:: 0.7
-
-Writing own filters is very easy. All you have to do is to subclass
-the `Filter` class and override the `filter` method. Additionally a
-filter is instantiated with some keyword arguments you can use to
-adjust the behavior of your filter.
-
-
-Subclassing Filters
-===================
-
-As an example, we write a filter that converts all `Name.Function` tokens
-to normal `Name` tokens to make the output less colorful.
-
-.. sourcecode:: python
-
-    from pygments.util import get_bool_opt
-    from pygments.token import Name
-    from pygments.filter import Filter
-
-    class UncolorFilter(Filter):
-
-        def __init__(self, **options):
-            Filter.__init__(self, **options)
-            self.class_too = get_bool_opt(options, 'classtoo')
-
-        def filter(self, lexer, stream):
-            for ttype, value in stream:
-                if ttype is Name.Function or (self.class_too and
-                                              ttype is Name.Class):
-                    ttype = Name
-                yield ttype, value
-
-Some notes on the `lexer` argument: that can be quite confusing since it doesn't
-need to be a lexer instance. If a filter was added by using the `add_filter()`
-function of lexers, that lexer is registered for the filter. In that case
-`lexer` will refer to the lexer that has registered the filter. It *can* be used
-to access options passed to a lexer. Because it could be `None` you always have
-to check for that case if you access it.
-
-
-Using a decorator
-=================
-
-You can also use the `simplefilter` decorator from the `pygments.filter` module:
-
-.. sourcecode:: python
-
-    from pygments.util import get_bool_opt
-    from pygments.token import Name
-    from pygments.filter import simplefilter
-
-
-    @simplefilter
-    def uncolor(self, lexer, stream, options):
-        class_too = get_bool_opt(options, 'classtoo')
-        for ttype, value in stream:
-            if ttype is Name.Function or (class_too and
-                                          ttype is Name.Class):
-                ttype = Name
-            yield ttype, value
-
-The decorator automatically subclasses an internal filter class and uses the
-decorated function as a method for filtering.  (That's why there is a `self`
-argument that you probably won't end up using in the method.)

-Filters
-=======
-
-.. versionadded:: 0.7
-
-You can filter token streams coming from lexers to improve or annotate the
-output. For example, you can highlight special words in comments, convert
-keywords to upper or lowercase to enforce a style guide etc.
-
-To apply a filter, you can use the `add_filter()` method of a lexer:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.lexers import PythonLexer
-    >>> l = PythonLexer()
-    >>> # add a filter given by a string and options
-    >>> l.add_filter('codetagify', case='lower')
-    >>> l.filters
-    []
-    >>> from pygments.filters import KeywordCaseFilter
-    >>> # or give an instance
-    >>> l.add_filter(KeywordCaseFilter(case='lower'))
-
-The `add_filter()` method takes keyword arguments which are forwarded to
-the constructor of the filter.
-
-To get a list of all registered filters by name, you can use the
-`get_all_filters()` function from the `pygments.filters` module that returns an
-iterable for all known filters.
-
-If you want to write your own filter, have a look at :doc:`Write your own filter
-`.

-
-========================
-Write your own formatter
-========================
-
-As well as creating :doc:`your own lexer `, writing a new
-formatter for Pygments is easy and straightforward.
-
-A formatter is a class that is initialized with some keyword arguments (the
-formatter options) and that must provides a `format()` method.
-Additionally a formatter should provide a `get_style_defs()` method that
-returns the style definitions from the style in a form usable for the
-formatter's output format.
-
-
-Quickstart
-==========
-
-The most basic formatter shipped with Pygments is the `NullFormatter`. It just
-sends the value of a token to the output stream:
-
-.. sourcecode:: python
-
-    from pygments.formatter import Formatter
-
-    class NullFormatter(Formatter):
-        def format(self, tokensource, outfile):
-            for ttype, value in tokensource:
-                outfile.write(value)
-
-As you can see, the `format()` method is passed two parameters: `tokensource`
-and `outfile`. The first is an iterable of ``(token_type, value)`` tuples,
-the latter a file like object with a `write()` method.
-
-Because the formatter is that basic it doesn't overwrite the `get_style_defs()`
-method.
-
-
-Styles

-Styles aren't instantiated but their metaclass provides some class functions
-so that you can access the style definitions easily.
-
-Styles are iterable and yield tuples in the form ``(ttype, d)`` where `ttype`
-is a token and `d` is a dict with the following keys:
-
-``'color'``
-    Hexadecimal color value (eg: ``'ff0000'`` for red) or `None` if not
-    defined.
-
-``'bold'``
-    `True` if the value should be bold
-
-``'italic'``
-    `True` if the value should be italic
-
-``'underline'``
-    `True` if the value should be underlined
-
-``'bgcolor'``
-    Hexadecimal color value for the background (eg: ``'eeeeeee'`` for light
-    gray) or `None` if not defined.
-
-``'border'``
-    Hexadecimal color value for the border (eg: ``'0000aa'`` for a dark
-    blue) or `None` for no border.
-
-Additional keys might appear in the future, formatters should ignore all keys
-they don't support.

-HTML 3.2 Formatter
-==================
-
-For an more complex example, let's implement a HTML 3.2 Formatter. We don't
-use CSS but inline markup (````, ````, etc). Because this isn't good
-style this formatter isn't in the standard library ;-)
-
-.. sourcecode:: python
-
-    from pygments.formatter import Formatter
-
-    class OldHtmlFormatter(Formatter):
-
-        def __init__(self, **options):
-            Formatter.__init__(self, **options)
-
-            # create a dict of (start, end) tuples that wrap the
-            # value of a token so that we can use it in the format
-            # method later
-            self.styles = {}
-
-            # we iterate over the `_styles` attribute of a style item
-            # that contains the parsed style values.
-            for token, style in self.style:
-                start = end = ''
-                # a style item is a tuple in the following form:
-                # colors are readily specified in hex: 'RRGGBB'
-                if style['color']:
-                    start += '' % style['color']
-                    end = '' + end
-                if style['bold']:
-                    start += ''
-                    end = '' + end
-                if style['italic']:
-                    start += ''
-                    end = '' + end
-                if style['underline']:
-                    start += ''
-                    end = '' + end
-                self.styles[token] = (start, end)
-
-        def format(self, tokensource, outfile):
-            # lastval is a string we use for caching
-            # because it's possible that an lexer yields a number
-            # of consecutive tokens with the same token type.
-            # to minimize the size of the generated html markup we
-            # try to join the values of same-type tokens here
-            lastval = ''
-            lasttype = None
-
-            # wrap the whole output with 
      -            outfile.write('
      ')
-
-            for ttype, value in tokensource:
-                # if the token type doesn't exist in the stylemap
-                # we try it with the parent of the token type
-                # eg: parent of Token.Literal.String.Double is
-                # Token.Literal.String
-                while ttype not in self.styles:
-                    ttype = ttype.parent
-                if ttype == lasttype:
-                    # the current token type is the same of the last
-                    # iteration. cache it
-                    lastval += value
-                else:
-                    # not the same token as last iteration, but we
-                    # have some data in the buffer. wrap it with the
-                    # defined style and write it to the output file
-                    if lastval:
-                        stylebegin, styleend = self.styles[lasttype]
-                        outfile.write(stylebegin + lastval + styleend)
-                    # set lastval/lasttype to current values
-                    lastval = value
-                    lasttype = ttype
-
-            # if something is left in the buffer, write it to the
-            # output file, then close the opened 
       tag
-            if lastval:
-                stylebegin, styleend = self.styles[lasttype]
-                outfile.write(stylebegin + lastval + styleend)
-            outfile.write('
      \n')
-
-The comments should explain it. Again, this formatter doesn't override the
-`get_style_defs()` method. If we would have used CSS classes instead of
-inline HTML markup, we would need to generate the CSS first. For that
-purpose the `get_style_defs()` method exists:
-
-
-Generating Style Definitions
-============================
-
-Some formatters like the `LatexFormatter` and the `HtmlFormatter` don't
-output inline markup but reference either macros or css classes. Because
-the definitions of those are not part of the output, the `get_style_defs()`
-method exists. It is passed one parameter (if it's used and how it's used
-is up to the formatter) and has to return a string or ``None``.

-Available formatters
-====================
-
-This page lists all builtin formatters.
-
-Common options
-==============
-
-All formatters support these options:
-
-`encoding`
-    If given, must be an encoding name (such as ``"utf-8"``). This will
-    be used to convert the token strings (which are Unicode strings)
-    to byte strings in the output (default: ``None``).
-    It will also be written in an encoding declaration suitable for the
-    document format if the `full` option is given (e.g. a ``meta
-    content-type`` directive in HTML or an invocation of the `inputenc`
-    package in LaTeX).
-
-    If this is ``""`` or ``None``, Unicode strings will be written
-    to the output file, which most file-like objects do not support.
-    For example, `pygments.highlight()` will return a Unicode string if
-    called with no `outfile` argument and a formatter that has `encoding`
-    set to ``None`` because it uses a `StringIO.StringIO` object that
-    supports Unicode arguments to `write()`. Using a regular file object
-    wouldn't work.
-
-    .. versionadded:: 0.6
-
-`outencoding`
-    When using Pygments from the command line, any `encoding` option given is
-    passed to the lexer and the formatter. This is sometimes not desirable,
-    for example if you want to set the input encoding to ``"guess"``.
-    Therefore, `outencoding` has been introduced which overrides `encoding`
-    for the formatter if given.
-
-    .. versionadded:: 0.7
-
-
-Formatter classes

-=====================
-Use Pygments in Java
-=====================
-
-Thanks to `Jython `_ it is possible to use Pygments in
-Java.
-
-This page is a simple tutorial to get an idea of how this works. You can
-then look at the `Jython documentation `_ for more
-advanced uses.
-
-Since version 1.5, Pygments is deployed on `Maven Central
-`_ as a JAR, as is Jython
-which makes it a lot easier to create a Java project.
-
-Here is an example of a `Maven `_ ``pom.xml`` file for a
-project running Pygments:
-
-.. sourcecode:: xml
-
-    
-
-    
-      4.0.0
-      example
-      example
-      1.0-SNAPSHOT
-      
-        
-          org.python
-          jython-standalone
-          2.5.3
-        
-        
-          org.pygments
-          pygments
-          1.5
-          runtime
-        
-      
-    
-
-The following Java example:
-
-.. sourcecode:: java
-
-    PythonInterpreter interpreter = new PythonInterpreter();
-
-    // Set a variable with the content you want to work with
-    interpreter.set("code", code);
-
-    // Simple use Pygments as you would in Python
-    interpreter.exec("from pygments import highlight\n"
-        + "from pygments.lexers import PythonLexer\n"
-        + "from pygments.formatters import HtmlFormatter\n"
-        + "\nresult = highlight(code, PythonLexer(), HtmlFormatter())");
-
-    // Get the result that has been set in a variable
-    System.out.println(interpreter.get("result", String.class));
-
-will print something like:
-
-.. sourcecode:: html
-
-    
      
-    
      print "Hello World"
      
-

-====================
-Write your own lexer
-====================
-
-If a lexer for your favorite language is missing in the Pygments package, you
-can easily write your own and extend Pygments.
-
-All you need can be found inside the :mod:`pygments.lexer` module.  As you can
-read in the :doc:`API documentation `, a lexer is a class that is
-initialized with some keyword arguments (the lexer options) and that provides a
-:meth:`.get_tokens_unprocessed()` method which is given a string or unicode
-object with the data to lex.
-
-The :meth:`.get_tokens_unprocessed()` method must return an iterator or iterable
-containing tuples in the form ``(index, token, value)``.  Normally you don't
-need to do this since there are base lexers that do most of the work and that
-you can subclass.
-
-
-RegexLexer
-==========
-
-The lexer base class used by almost all of Pygments' lexers is the
-:class:`RegexLexer`.  This class allows you to define lexing rules in terms of
-*regular expressions* for different *states*.
-
-States are groups of regular expressions that are matched against the input
-string at the *current position*.  If one of these expressions matches, a
-corresponding action is performed (such as yielding a token with a specific
-type, or changing state), the current position is set to where the last match
-ended and the matching process continues with the first regex of the current
-state.
-
-Lexer states are kept on a stack: each time a new state is entered, the new
-state is pushed onto the stack.  The most basic lexers (like the `DiffLexer`)
-just need one state.
-
-Each state is defined as a list of tuples in the form (`regex`, `action`,
-`new_state`) where the last item is optional.  In the most basic form, `action`
-is a token type (like `Name.Builtin`).  That means: When `regex` matches, emit a
-token with the match text and type `tokentype` and push `new_state` on the state
-stack.  If the new state is ``'#pop'``, the topmost state is popped from the
-stack instead.  To pop more than one state, use ``'#pop:2'`` and so on.
-``'#push'`` is a synonym for pushing the current state on the stack.
-
-The following example shows the `DiffLexer` from the builtin lexers.  Note that
-it contains some additional attributes `name`, `aliases` and `filenames` which
-aren't required for a lexer.  They are used by the builtin lexer lookup
-functions. ::
-
-    from pygments.lexer import RegexLexer
-    from pygments.token import *
-
-    class DiffLexer(RegexLexer):
-        name = 'Diff'
-        aliases = ['diff']
-        filenames = ['*.diff']
-
-        tokens = {
-            'root': [
-                (r' .*\n', Text),
-                (r'\+.*\n', Generic.Inserted),
-                (r'-.*\n', Generic.Deleted),
-                (r'@.*\n', Generic.Subheading),
-                (r'Index.*\n', Generic.Heading),
-                (r'=.*\n', Generic.Heading),
-                (r'.*\n', Text),
-            ]
-        }
-
-As you can see this lexer only uses one state.  When the lexer starts scanning
-the text, it first checks if the current character is a space.  If this is true
-it scans everything until newline and returns the data as a `Text` token (which
-is the "no special highlighting" token).
-
-If this rule doesn't match, it checks if the current char is a plus sign.  And
-so on.
-
-If no rule matches at the current position, the current char is emitted as an
-`Error` token that indicates a lexing error, and the position is increased by
-one.
-
-
-Adding and testing a new lexer
-==============================
-
-To make Pygments aware of your new lexer, you have to perform the following
-steps:
-
-First, change to the current directory containing the Pygments source code:
-
-.. code-block:: console
-
-    $ cd .../pygments-main
-
-Select a matching module under ``pygments/lexers``, or create a new module for
-your lexer class.
-
-Next, make sure the lexer is known from outside of the module.  All modules in
-the ``pygments.lexers`` specify ``__all__``. For example, ``esoteric.py`` sets::
-
-    __all__ = ['BrainfuckLexer', 'BefungeLexer', ...]
-
-Simply add the name of your lexer class to this list.
-
-Finally the lexer can be made publicly known by rebuilding the lexer mapping:
-
-.. code-block:: console
-
-    $ make mapfiles
-
-To test the new lexer, store an example file with the proper extension in
-``tests/examplefiles``.  For example, to test your ``DiffLexer``, add a
-``tests/examplefiles/example.diff`` containing a sample diff output.
-
-Now you can use pygmentize to render your example to HTML:
-
-.. code-block:: console
-
-    $ ./pygmentize -O full -f html -o /tmp/example.html tests/examplefiles/example.diff
-
-Note that this explicitly calls the ``pygmentize`` in the current directory
-by preceding it with ``./``. This ensures your modifications are used.
-Otherwise a possibly already installed, unmodified version without your new
-lexer would have been called from the system search path (``$PATH``).
-
-To view the result, open ``/tmp/example.html`` in your browser.
-
-Once the example renders as expected, you should run the complete test suite:
-
-.. code-block:: console
-
-    $ make test
-
-It also tests that your lexer fulfills the lexer API and certain invariants,
-such as that the concatenation of all token text is the same as the input text.
-
-
-Regex Flags
-===========
-
-You can either define regex flags locally in the regex (``r'(?x)foo bar'``) or
-globally by adding a `flags` attribute to your lexer class.  If no attribute is
-defined, it defaults to `re.MULTILINE`.  For more information about regular
-expression flags see the page about `regular expressions`_ in the Python
-documentation.
-
-.. _regular expressions: http://docs.python.org/library/re.html#regular-expression-syntax
-
-
-Scanning multiple tokens at once
-================================
-
-So far, the `action` element in the rule tuple of regex, action and state has
-been a single token type.  Now we look at the first of several other possible
-values.
-
-Here is a more complex lexer that highlights INI files.  INI files consist of
-sections, comments and ``key = value`` pairs::
-
-    from pygments.lexer import RegexLexer, bygroups
-    from pygments.token import *
-
-    class IniLexer(RegexLexer):
-        name = 'INI'
-        aliases = ['ini', 'cfg']
-        filenames = ['*.ini', '*.cfg']
-
-        tokens = {
-            'root': [
-                (r'\s+', Text),
-                (r';.*?$', Comment),
-                (r'\[.*?\]$', Keyword),
-                (r'(.*?)(\s*)(=)(\s*)(.*?)$',
-                 bygroups(Name.Attribute, Text, Operator, Text, String))
-            ]
-        }
-
-The lexer first looks for whitespace, comments and section names.  Later it
-looks for a line that looks like a key, value pair, separated by an ``'='``
-sign, and optional whitespace.
-
-The `bygroups` helper yields each capturing group in the regex with a different
-token type.  First the `Name.Attribute` token, then a `Text` token for the
-optional whitespace, after that a `Operator` token for the equals sign. Then a
-`Text` token for the whitespace again.  The rest of the line is returned as
-`String`.
-
-Note that for this to work, every part of the match must be inside a capturing
-group (a ``(...)``), and there must not be any nested capturing groups.  If you
-nevertheless need a group, use a non-capturing group defined using this syntax:
-``(?:some|words|here)`` (note the ``?:`` after the beginning parenthesis).
-
-If you find yourself needing a capturing group inside the regex which shouldn't
-be part of the output but is used in the regular expressions for backreferencing
-(eg: ``r'(<(foo|bar)>)(.*?)()'``), you can pass `None` to the bygroups
-function and that group will be skipped in the output.
-
-
-Changing states
-===============
-
-Many lexers need multiple states to work as expected.  For example, some
-languages allow multiline comments to be nested.  Since this is a recursive
-pattern it's impossible to lex just using regular expressions.
-
-Here is a lexer that recognizes C++ style comments (multi-line with ``/* */``
-and single-line with ``//`` until end of line)::
-
-    from pygments.lexer import RegexLexer
-    from pygments.token import *
-
-    class CppCommentLexer(RegexLexer):
-        name = 'Example Lexer with states'
-
-        tokens = {
-            'root': [
-                (r'[^/]+', Text),
-                (r'/\*', Comment.Multiline, 'comment'),
-                (r'//.*?$', Comment.Singleline),
-                (r'/', Text)
-            ],
-            'comment': [
-                (r'[^*/]', Comment.Multiline),
-                (r'/\*', Comment.Multiline, '#push'),
-                (r'\*/', Comment.Multiline, '#pop'),
-                (r'[*/]', Comment.Multiline)
-            ]
-        }
-
-This lexer starts lexing in the ``'root'`` state. It tries to match as much as
-possible until it finds a slash (``'/'``).  If the next character after the slash
-is an asterisk (``'*'``) the `RegexLexer` sends those two characters to the
-output stream marked as `Comment.Multiline` and continues lexing with the rules
-defined in the ``'comment'`` state.
-
-If there wasn't an asterisk after the slash, the `RegexLexer` checks if it's a
-Singleline comment (i.e. followed by a second slash).  If this also wasn't the
-case it must be a single slash, which is not a comment starter (the separate
-regex for a single slash must also be given, else the slash would be marked as
-an error token).
-
-Inside the ``'comment'`` state, we do the same thing again.  Scan until the
-lexer finds a star or slash.  If it's the opening of a multiline comment, push
-the ``'comment'`` state on the stack and continue scanning, again in the
-``'comment'`` state.  Else, check if it's the end of the multiline comment.  If
-yes, pop one state from the stack.
-
-Note: If you pop from an empty stack you'll get an `IndexError`.  (There is an
-easy way to prevent this from happening: don't ``'#pop'`` in the root state).
-
-If the `RegexLexer` encounters a newline that is flagged as an error token, the
-stack is emptied and the lexer continues scanning in the ``'root'`` state.  This
-can help producing error-tolerant highlighting for erroneous input, e.g. when a
-single-line string is not closed.
-
-
-Advanced state tricks
-=====================
-
-There are a few more things you can do with states:
-
-- You can push multiple states onto the stack if you give a tuple instead of a
-  simple string as the third item in a rule tuple.  For example, if you want to
-  match a comment containing a directive, something like:
-
-  .. code-block:: text
-
-      /*     rest of comment */
-
-  you can use this rule::
-
-      tokens = {
-          'root': [
-              (r'/\* <', Comment, ('comment', 'directive')),
-              ...
-          ],
-          'directive': [
-              (r'[^>]*', Comment.Directive),
-              (r'>', Comment, '#pop'),
-          ],
-          'comment': [
-              (r'[^*]+', Comment),
-              (r'\*/', Comment, '#pop'),
-              (r'\*', Comment),
-          ]
-      }
-
-  When this encounters the above sample, first ``'comment'`` and ``'directive'``
-  are pushed onto the stack, then the lexer continues in the directive state
-  until it finds the closing ``>``, then it continues in the comment state until
-  the closing ``*/``.  Then, both states are popped from the stack again and
-  lexing continues in the root state.
-
-  .. versionadded:: 0.9
-     The tuple can contain the special ``'#push'`` and ``'#pop'`` (but not
-     ``'#pop:n'``) directives.
-
-
-- You can include the rules of a state in the definition of another.  This is
-  done by using `include` from `pygments.lexer`::
-
-      from pygments.lexer import RegexLexer, bygroups, include
-      from pygments.token import *
-
-      class ExampleLexer(RegexLexer):
-          tokens = {
-              'comments': [
-                  (r'/\*.*?\*/', Comment),
-                  (r'//.*?\n', Comment),
-              ],
-              'root': [
-                  include('comments'),
-                  (r'(function )(\w+)( {)',
-                   bygroups(Keyword, Name, Keyword), 'function'),
-                  (r'.', Text),
-              ],
-              'function': [
-                  (r'[^}/]+', Text),
-                  include('comments'),
-                  (r'/', Text),
-                  (r'\}', Keyword, '#pop'),
-              ]
-          }
-
-  This is a hypothetical lexer for a language that consist of functions and
-  comments.  Because comments can occur at toplevel and in functions, we need
-  rules for comments in both states.  As you can see, the `include` helper saves
-  repeating rules that occur more than once (in this example, the state
-  ``'comment'`` will never be entered by the lexer, as it's only there to be
-  included in ``'root'`` and ``'function'``).
-
-- Sometimes, you may want to "combine" a state from existing ones.  This is
-  possible with the `combined` helper from `pygments.lexer`.
-
-  If you, instead of a new state, write ``combined('state1', 'state2')`` as the
-  third item of a rule tuple, a new anonymous state will be formed from state1
-  and state2 and if the rule matches, the lexer will enter this state.
-
-  This is not used very often, but can be helpful in some cases, such as the
-  `PythonLexer`'s string literal processing.
-
-- If you want your lexer to start lexing in a different state you can modify the
-  stack by overriding the `get_tokens_unprocessed()` method::
-
-      from pygments.lexer import RegexLexer
-
-      class ExampleLexer(RegexLexer):
-          tokens = {...}
-
-          def get_tokens_unprocessed(self, text, stack=('root', 'otherstate')):
-              for item in RegexLexer.get_tokens_unprocessed(text, stack):
-                  yield item
-
-  Some lexers like the `PhpLexer` use this to make the leading ``', Name.Tag),
-            ],
-            'script-content': [
-                (r'(.+?)(<\s*/\s*script\s*>)',
-                 bygroups(using(JavascriptLexer), Name.Tag),
-                 '#pop'),
-            ]
-        }
-
-Here the content of a ```` end tag is processed by the `JavascriptLexer`,
-while the end tag is yielded as a normal token with the `Name.Tag` type.
-
-Also note the ``(r'<\s*script\s*', Name.Tag, ('script-content', 'tag'))`` rule.
-Here, two states are pushed onto the state stack, ``'script-content'`` and
-``'tag'``.  That means that first ``'tag'`` is processed, which will lex
-attributes and the closing ``>``, then the ``'tag'`` state is popped and the
-next state on top of the stack will be ``'script-content'``.
-
-Since you cannot refer to the class currently being defined, use `this`
-(imported from `pygments.lexer`) to refer to the current lexer class, i.e.
-``using(this)``.  This construct may seem unnecessary, but this is often the
-most obvious way of lexing arbitrary syntax between fixed delimiters without
-introducing deeply nested states.
-
-The `using()` helper has a special keyword argument, `state`, which works as
-follows: if given, the lexer to use initially is not in the ``"root"`` state,
-but in the state given by this argument.  This does not work with advanced
-`RegexLexer` subclasses such as `ExtendedRegexLexer` (see below).
-
-Any other keywords arguments passed to `using()` are added to the keyword
-arguments used to create the lexer.
-
-
-Delegating Lexer
-================
-
-Another approach for nested lexers is the `DelegatingLexer` which is for example
-used for the template engine lexers.  It takes two lexers as arguments on
-initialisation: a `root_lexer` and a `language_lexer`.
-
-The input is processed as follows: First, the whole text is lexed with the
-`language_lexer`.  All tokens yielded with the special type of ``Other`` are
-then concatenated and given to the `root_lexer`.  The language tokens of the
-`language_lexer` are then inserted into the `root_lexer`'s token stream at the
-appropriate positions. ::
-
-    from pygments.lexer import DelegatingLexer
-    from pygments.lexers.web import HtmlLexer, PhpLexer
-
-    class HtmlPhpLexer(DelegatingLexer):
-        def __init__(self, **options):
-            super(HtmlPhpLexer, self).__init__(HtmlLexer, PhpLexer, **options)
-
-This procedure ensures that e.g. HTML with template tags in it is highlighted
-correctly even if the template tags are put into HTML tags or attributes.
-
-If you want to change the needle token ``Other`` to something else, you can give
-the lexer another token type as the third parameter::
-
-    DelegatingLexer.__init__(MyLexer, OtherLexer, Text, **options)
-
-
-Callbacks
-=========
-
-Sometimes the grammar of a language is so complex that a lexer would be unable
-to process it just by using regular expressions and stacks.
-
-For this, the `RegexLexer` allows callbacks to be given in rule tuples, instead
-of token types (`bygroups` and `using` are nothing else but preimplemented
-callbacks).  The callback must be a function taking two arguments:
-
-* the lexer itself
-* the match object for the last matched rule
-
-The callback must then return an iterable of (or simply yield) ``(index,
-tokentype, value)`` tuples, which are then just passed through by
-`get_tokens_unprocessed()`.  The ``index`` here is the position of the token in
-the input string, ``tokentype`` is the normal token type (like `Name.Builtin`),
-and ``value`` the associated part of the input string.
-
-You can see an example here::
-
-    from pygments.lexer import RegexLexer
-    from pygments.token import Generic
-
-    class HypotheticLexer(RegexLexer):
-
-        def headline_callback(lexer, match):
-            equal_signs = match.group(1)
-            text = match.group(2)
-            yield match.start(), Generic.Headline, equal_signs + text + equal_signs
-
-        tokens = {
-            'root': [
-                (r'(=+)(.*?)(\1)', headline_callback)
-            ]
-        }
-
-If the regex for the `headline_callback` matches, the function is called with
-the match object.  Note that after the callback is done, processing continues
-normally, that is, after the end of the previous match.  The callback has no
-possibility to influence the position.
-
-There are not really any simple examples for lexer callbacks, but you can see
-them in action e.g. in the `SMLLexer` class in `ml.py`_.
-
-.. _ml.py: http://bitbucket.org/birkenfeld/pygments-main/src/tip/pygments/lexers/ml.py
-
-
-The ExtendedRegexLexer class
-============================
-
-The `RegexLexer`, even with callbacks, unfortunately isn't powerful enough for
-the funky syntax rules of languages such as Ruby.
-
-But fear not; even then you don't have to abandon the regular expression
-approach: Pygments has a subclass of `RegexLexer`, the `ExtendedRegexLexer`.
-All features known from RegexLexers are available here too, and the tokens are
-specified in exactly the same way, *except* for one detail:
-
-The `get_tokens_unprocessed()` method holds its internal state data not as local
-variables, but in an instance of the `pygments.lexer.LexerContext` class, and
-that instance is passed to callbacks as a third argument. This means that you
-can modify the lexer state in callbacks.
-
-The `LexerContext` class has the following members:
-
-* `text` -- the input text
-* `pos` -- the current starting position that is used for matching regexes
-* `stack` -- a list containing the state stack
-* `end` -- the maximum position to which regexes are matched, this defaults to
-  the length of `text`
-
-Additionally, the `get_tokens_unprocessed()` method can be given a
-`LexerContext` instead of a string and will then process this context instead of
-creating a new one for the string argument.
-
-Note that because you can set the current position to anything in the callback,
-it won't be automatically be set by the caller after the callback is finished.
-For example, this is how the hypothetical lexer above would be written with the
-`ExtendedRegexLexer`::
-
-    from pygments.lexer import ExtendedRegexLexer
-    from pygments.token import Generic
-
-    class ExHypotheticLexer(ExtendedRegexLexer):
-
-        def headline_callback(lexer, match, ctx):
-            equal_signs = match.group(1)
-            text = match.group(2)
-            yield match.start(), Generic.Headline, equal_signs + text + equal_signs
-            ctx.pos = match.end()
-
-        tokens = {
-            'root': [
-                (r'(=+)(.*?)(\1)', headline_callback)
-            ]
-        }
-
-This might sound confusing (and it can really be). But it is needed, and for an
-example look at the Ruby lexer in `ruby.py`_.
-
-.. _ruby.py: https://bitbucket.org/birkenfeld/pygments-main/src/tip/pygments/lexers/ruby.py
-
-
-Handling Lists of Keywords
-==========================
-
-For a relatively short list (hundreds) you can construct an optimized regular
-expression directly using ``words()`` (longer lists, see next section).  This
-function handles a few things for you automatically, including escaping
-metacharacters and Python's first-match rather than longest-match in
-alternations.  Feel free to put the lists themselves in
-``pygments/lexers/_$lang_builtins.py`` (see examples there), and generated by
-code if possible.
-
-An example of using ``words()`` is something like::
-
-    from pygments.lexer import RegexLexer, words, Name
-
-    class MyLexer(RegexLexer):
-
-        tokens = {
-            'root': [
-                (words(('else', 'elseif'), suffix=r'\b'), Name.Builtin),
-                (r'\w+', Name),
-            ],
-        }
-
-As you can see, you can add ``prefix`` and ``suffix`` parts to the constructed
-regex.
-
-
-Modifying Token Streams
-=======================
-
-Some languages ship a lot of builtin functions (for example PHP).  The total
-amount of those functions differs from system to system because not everybody
-has every extension installed.  In the case of PHP there are over 3000 builtin
-functions.  That's an incredibly huge amount of functions, much more than you
-want to put into a regular expression.
-
-But because only `Name` tokens can be function names this is solvable by
-overriding the ``get_tokens_unprocessed()`` method.  The following lexer
-subclasses the `PythonLexer` so that it highlights some additional names as
-pseudo keywords::
-
-    from pygments.lexers.python import PythonLexer
-    from pygments.token import Name, Keyword
-
-    class MyPythonLexer(PythonLexer):
-        EXTRA_KEYWORDS = set(('foo', 'bar', 'foobar', 'barfoo', 'spam', 'eggs'))
-
-        def get_tokens_unprocessed(self, text):
-            for index, token, value in PythonLexer.get_tokens_unprocessed(self, text):
-                if token is Name and value in self.EXTRA_KEYWORDS:
-                    yield index, Keyword.Pseudo, value
-                else:
-                    yield index, token, value
-
-The `PhpLexer` and `LuaLexer` use this method to resolve builtin functions.

-Available lexers
-================
-
-This page lists all available builtin lexers and the options they take.
-
-Currently, **all lexers** support these options:
-
-`stripnl`
-    Strip leading and trailing newlines from the input (default: ``True``)
-
-`stripall`
-    Strip all leading and trailing whitespace from the input (default:
-    ``False``).
-
-`ensurenl`
-    Make sure that the input ends with a newline (default: ``True``).  This
-    is required for some lexers that consume input linewise.
-
-    .. versionadded:: 1.3
-
-`tabsize`
-    If given and greater than 0, expand tabs in the input (default: ``0``).
-
-`encoding`
-    If given, must be an encoding name (such as ``"utf-8"``). This encoding
-    will be used to convert the input string to Unicode (if it is not already
-    a Unicode string). The default is ``"guess"``.
-
-    If this option is set to ``"guess"``, a simple UTF-8 vs. Latin-1
-    detection is used, if it is set to ``"chardet"``, the
-    `chardet library `_ is used to
-    guess the encoding of the input.
-
-    .. versionadded:: 0.6
-
-
-The "Short Names" field lists the identifiers that can be used with the
-`get_lexer_by_name()` function.
-
-These lexers are builtin and can be imported from `pygments.lexers`:
-
-.. pygmentsdoc:: lexers
-
-
-Iterating over all lexers
--------------------------
-
-.. versionadded:: 0.6
-
-To get all lexers (both the builtin and the plugin ones), you can
-use the `get_all_lexers()` function from the `pygments.lexers`
-module:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.lexers import get_all_lexers
-    >>> i = get_all_lexers()
-    >>> i.next()
-    ('Diff', ('diff',), ('*.diff', '*.patch'), ('text/x-diff', 'text/x-patch'))
-    >>> i.next()
-    ('Delphi', ('delphi', 'objectpascal', 'pas', 'pascal'), ('*.pas',), ('text/x-pascal',))
-    >>> i.next()
-    ('XML+Ruby', ('xml+erb', 'xml+ruby'), (), ())
-
-As you can see, the return value is an iterator which yields tuples
-in the form ``(name, aliases, filetypes, mimetypes)``.

-Using Pygments with MoinMoin
-============================
-
-From Pygments 0.7, the source distribution ships a `Moin`_ parser plugin that
-can be used to get Pygments highlighting in Moin wiki pages.
-
-To use it, copy the file `external/moin-parser.py` from the Pygments
-distribution to the `data/plugin/parser` subdirectory of your Moin instance.
-Edit the options at the top of the file (currently ``ATTACHMENTS`` and
-``INLINESTYLES``) and rename the file to the name that the parser directive
-should have. For example, if you name the file ``code.py``, you can get a
-highlighted Python code sample with this Wiki markup::
-
-    {{{
-    #!code python
-    [...]
-    }}}
-
-where ``python`` is the Pygments name of the lexer to use.
-
-Additionally, if you set the ``ATTACHMENTS`` option to True, Pygments will also
-be called for all attachments for whose filenames there is no other parser
-registered.
-
-You are responsible for including CSS rules that will map the Pygments CSS
-classes to colors. You can output a stylesheet file with `pygmentize`, put it
-into the `htdocs` directory of your Moin instance and then include it in the
-`stylesheets` configuration option in the Moin config, e.g.::
-
-    stylesheets = [('screen', '/htdocs/pygments.css')]
-
-If you do not want to do that and are willing to accept larger HTML output, you
-can set the ``INLINESTYLES`` option to True.

-Register Plugins
-================
-
-If you want to extend Pygments without hacking the sources, but want to
-use the lexer/formatter/style/filter lookup functions (`lexers.get_lexer_by_name`
-et al.), you can use `setuptools`_ entrypoints to add new lexers, formatters
-or styles as if they were in the Pygments core.
-
-.. _setuptools: http://peak.telecommunity.com/DevCenter/setuptools
-
-That means you can use your highlighter modules with the `pygmentize` script,
-which relies on the mentioned functions.
-
-
-Entrypoints
-===========
-
-Here is a list of setuptools entrypoints that Pygments understands:
-
-`pygments.lexers`
-
-    This entrypoint is used for adding new lexers to the Pygments core.
-    The name of the entrypoint values doesn't really matter, Pygments extracts
-    required metadata from the class definition:
-
-    .. sourcecode:: ini
-
-        [pygments.lexers]
-        yourlexer = yourmodule:YourLexer
-
-    Note that you have to define ``name``, ``aliases`` and ``filename``
-    attributes so that you can use the highlighter from the command line:
-
-    .. sourcecode:: python
-
-        class YourLexer(...):
-            name = 'Name Of Your Lexer'
-            aliases = ['alias']
-            filenames = ['*.ext']
-
-
-`pygments.formatters`
-
-    You can use this entrypoint to add new formatters to Pygments. The
-    name of an entrypoint item is the name of the formatter. If you
-    prefix the name with a slash it's used as a filename pattern:
-
-    .. sourcecode:: ini
-
-        [pygments.formatters]
-        yourformatter = yourmodule:YourFormatter
-        /.ext = yourmodule:YourFormatter
-
-
-`pygments.styles`
-
-    To add a new style you can use this entrypoint. The name of the entrypoint
-    is the name of the style:
-
-    .. sourcecode:: ini
-
-        [pygments.styles]
-        yourstyle = yourmodule:YourStyle
-
-
-`pygments.filters`
-
-    Use this entrypoint to register a new filter. The name of the
-    entrypoint is the name of the filter:
-
-    .. sourcecode:: ini
-
-        [pygments.filters]
-        yourfilter = yourmodule:YourFilter
-
-
-How To Use Entrypoints
-======================
-
-This documentation doesn't explain how to use those entrypoints because this is
-covered in the `setuptools documentation`_. That page should cover everything
-you need to write a plugin.
-
-.. _setuptools documentation: http://peak.telecommunity.com/DevCenter/setuptools
-
-
-Extending The Core
-==================
-
-If you have written a Pygments plugin that is open source, please inform us
-about that. There is a high chance that we'll add it to the Pygments
-distribution.

-===========================
-Introduction and Quickstart
-===========================
-
-
-Welcome to Pygments! This document explains the basic concepts and terms and
-gives a few examples of how to use the library.
-
-
-Architecture
-============
-
-There are four types of components that work together highlighting a piece of
-code:
-
-* A **lexer** splits the source into tokens, fragments of the source that
-  have a token type that determines what the text represents semantically
-  (e.g., keyword, string, or comment). There is a lexer for every language
-  or markup format that Pygments supports.
-* The token stream can be piped through **filters**, which usually modify
-  the token types or text fragments, e.g. uppercasing all keywords.
-* A **formatter** then takes the token stream and writes it to an output
-  file, in a format such as HTML, LaTeX or RTF.
-* While writing the output, a **style** determines how to highlight all the
-  different token types. It maps them to attributes like "red and bold".
-
-
-Example
-=======
-
-Here is a small example for highlighting Python code:
-
-.. sourcecode:: python
-
-    from pygments import highlight
-    from pygments.lexers import PythonLexer
-    from pygments.formatters import HtmlFormatter
-
-    code = 'print "Hello World"'
-    print highlight(code, PythonLexer(), HtmlFormatter())
-
-which prints something like this:
-
-.. sourcecode:: html
-
-    
      
-    
      print "Hello World"
      
-    
      
-
-As you can see, Pygments uses CSS classes (by default, but you can change that)
-instead of inline styles in order to avoid outputting redundant style information over
-and over. A CSS stylesheet that contains all CSS classes possibly used in the output
-can be produced by:
-
-.. sourcecode:: python
-
-    print HtmlFormatter().get_style_defs('.highlight')
-
-The argument to :func:`get_style_defs` is used as an additional CSS selector:
-the output may look like this:
-
-.. sourcecode:: css
-
-    .highlight .k { color: #AA22FF; font-weight: bold }
-    .highlight .s { color: #BB4444 }
-    ...
-
-
-Options
-=======
-
-The :func:`highlight()` function supports a fourth argument called *outfile*, it
-must be a file object if given. The formatted output will then be written to
-this file instead of being returned as a string.
-
-Lexers and formatters both support options. They are given to them as keyword
-arguments either to the class or to the lookup method:
-
-.. sourcecode:: python
-
-    from pygments import highlight
-    from pygments.lexers import get_lexer_by_name
-    from pygments.formatters import HtmlFormatter
-
-    lexer = get_lexer_by_name("python", stripall=True)
-    formatter = HtmlFormatter(linenos=True, cssclass="source")
-    result = highlight(code, lexer, formatter)
-
-This makes the lexer strip all leading and trailing whitespace from the input
-(`stripall` option), lets the formatter output line numbers (`linenos` option),
-and sets the wrapping ``
      ``'s class to ``source`` (instead of
-``highlight``).
-
-Important options include:
-
-`encoding` : for lexers and formatters
-   Since Pygments uses Unicode strings internally, this determines which
-   encoding will be used to convert to or from byte strings.
-`style` : for formatters
-   The name of the style to use when writing the output.
-
-

-:doc:`lexer ` and :doc:`formatters ` lists.
-
-For a documentation on filters, see :doc:`this page `.
-
-
-Lexer and formatter lookup
-==========================
-
-If you want to lookup a built-in lexer by its alias or a filename, you can use
-one of the following methods:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.lexers import (get_lexer_by_name,
-    ...     get_lexer_for_filename, get_lexer_for_mimetype)
-
-    >>> get_lexer_by_name('python')
-    
-
-    >>> get_lexer_for_filename('spam.rb')
-    
-
-    >>> get_lexer_for_mimetype('text/x-perl')
-    
-
-All these functions accept keyword arguments; they will be passed to the lexer
-as options.
-
-A similar API is available for formatters: use :func:`.get_formatter_by_name()`
-and :func:`.get_formatter_for_filename()` from the :mod:`pygments.formatters`
-module for this purpose.
-
-
-Guessing lexers
-===============
-
-If you don't know the content of the file, or you want to highlight a file
-whose extension is ambiguous, such as ``.html`` (which could contain plain HTML
-or some template tags), use these functions:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.lexers import guess_lexer, guess_lexer_for_filename
-
-    >>> guess_lexer('#!/usr/bin/python\nprint "Hello World!"')
-    
-
-    >>> guess_lexer_for_filename('test.py', 'print "Hello World!"')
-    
-
-:func:`.guess_lexer()` passes the given content to the lexer classes'
-:meth:`analyse_text()` method and returns the one for which it returns the
-highest number.
-
-All lexers have two different filename pattern lists: the primary and the
-secondary one. The :func:`.get_lexer_for_filename()` function only uses the
-primary list, whose entries are supposed to be unique among all lexers.
-:func:`.guess_lexer_for_filename()`, however, will first loop through all lexers
-and look at the primary and secondary filename patterns if the filename matches.
-If only one lexer matches, it is returned, else the guessing mechanism of
-:func:`.guess_lexer()` is used with the matching lexers.
-
-As usual, keyword arguments to these functions are given to the created lexer
-as options.    
-
-
-Command line usage
-==================
-
-You can use Pygments from the command line, using the :program:`pygmentize`
-script::
-
-    $ pygmentize test.py
-
-will highlight the Python file test.py using ANSI escape sequences
-(a.k.a. terminal colors) and print the result to standard output.
-
-To output HTML, use the ``-f`` option::
-
-    $ pygmentize -f html -o test.html test.py
-
-to write an HTML-highlighted version of test.py to the file test.html.
-Note that it will only be a snippet of HTML, if you want a full HTML document,
-use the "full" option::
-
-    $ pygmentize -f html -O full -o test.html test.py
-
-This will produce a full HTML document with included stylesheet.
-
-A style can be selected with ``-O style=``.
-
-If you need a stylesheet for an existing HTML file using Pygments CSS classes,
-it can be created with::
-
-    $ pygmentize -S default -f html > style.css
-
-where ``default`` is the style name.
-
-More options and tricks and be found in the :doc:`command line reference
-`.

-Using Pygments in ReST documents
-================================
-
-Many Python people use `ReST`_ for documentation their sourcecode, programs,
-scripts et cetera. This also means that documentation often includes sourcecode
-samples or snippets.
-
-You can easily enable Pygments support for your ReST texts using a custom
-directive -- this is also how this documentation displays source code.
-
-From Pygments 0.9, the directive is shipped in the distribution as
-`external/rst-directive.py`.  You can copy and adapt this code to your liking.
-
-.. removed -- too confusing
-   *Loosely related note:* The ReST lexer now recognizes ``.. sourcecode::`` and
-   ``.. code::`` directives and highlights the contents in the specified language
-   if the `handlecodeblocks` option is true.

-======
-Styles
-======
-
-Pygments comes with some builtin styles that work for both the HTML and
-LaTeX formatter.
-
-The builtin styles can be looked up with the `get_style_by_name` function:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.styles import get_style_by_name
-    >>> get_style_by_name('colorful')
-    
-
-You can pass a instance of a `Style` class to a formatter as the `style`
-option in form of a string:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.styles import get_style_by_name
-    >>> from pygments.formatters import HtmlFormatter
-    >>> HtmlFormatter(style='colorful').style
-    
-
-Or you can also import your own style (which must be a subclass of
-`pygments.style.Style`) and pass it to the formatter:
-
-.. sourcecode:: pycon
-
-    >>> from yourapp.yourmodule import YourStyle
-    >>> from pygments.formatters import HtmlFormatter
-    >>> HtmlFormatter(style=YourStyle).style
-    
-
-
-Creating Own Styles
-===================
-
-So, how to create a style? All you have to do is to subclass `Style` and
-define some styles:
-
-.. sourcecode:: python
-
-    from pygments.style import Style
-    from pygments.token import Keyword, Name, Comment, String, Error, \
-         Number, Operator, Generic
-
-    class YourStyle(Style):
-        default_style = ""
-        styles = {
-            Comment:                'italic #888',
-            Keyword:                'bold #005',
-            Name:                   '#f00',
-            Name.Function:          '#0f0',
-            Name.Class:             'bold #0f0',
-            String:                 'bg:#eee #111'
-        }
-
-That's it. There are just a few rules. When you define a style for `Name`
-the style automatically also affects `Name.Function` and so on. If you
-defined ``'bold'`` and you don't want boldface for a subtoken use ``'nobold'``.
-
-(Philosophy: the styles aren't written in CSS syntax since this way
-they can be used for a variety of formatters.)
-
-`default_style` is the style inherited by all token types.
-
-To make the style usable for Pygments, you must
-
-* either register it as a plugin (see :doc:`the plugin docs `)
-* or drop it into the `styles` subpackage of your Pygments distribution one style
-  class per style, where the file name is the style name and the class name is
-  `StylenameClass`. For example, if your style should be called
-  ``"mondrian"``, name the class `MondrianStyle`, put it into the file
-  ``mondrian.py`` and this file into the ``pygments.styles`` subpackage
-  directory.
-
-
-Style Rules
-===========
-
-Here a small overview of all allowed styles:
-
-``bold``
-    render text as bold
-``nobold``
-    don't render text as bold (to prevent subtokens being highlighted bold)
-``italic``
-    render text italic
-``noitalic``
-    don't render text as italic
-``underline``
-    render text underlined
-``nounderline``
-    don't render text underlined
-``bg:``
-    transparent background
-``bg:#000000``
-    background color (black)
-``border:``
-    no border
-``border:#ffffff``
-    border color (white)
-``#ff0000``
-    text color (red)
-``noinherit``
-    don't inherit styles from supertoken
-
-Note that there may not be a space between ``bg:`` and the color value
-since the style definition string is split at whitespace.
-Also, using named colors is not allowed since the supported color names
-vary for different formatters.
-
-Furthermore, not all lexers might support every style.
-
-
-Builtin Styles
-==============
-
-Pygments ships some builtin styles which are maintained by the Pygments team.
-
-To get a list of known styles you can use this snippet:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.styles import STYLE_MAP
-    >>> STYLE_MAP.keys()
-    ['default', 'emacs', 'friendly', 'colorful']
-
-
-Getting a list of available styles
-==================================
-
-.. versionadded:: 0.6
-
-Because it could be that a plugin registered a style, there is
-a way to iterate over all styles:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.styles import get_all_styles
-    >>> styles = list(get_all_styles())

-Builtin Tokens
-==============
-
-.. module:: pygments.token
-
-In the :mod:`pygments.token` module, there is a special object called `Token`
-that is used to create token types.
-
-You can create a new token type by accessing an attribute of `Token`:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.token import Token
-    >>> Token.String
-    Token.String
-    >>> Token.String is Token.String
-    True
-
-Note that tokens are singletons so you can use the ``is`` operator for comparing
-token types.
-
-As of Pygments 0.7 you can also use the ``in`` operator to perform set tests:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.token import Comment
-    >>> Comment.Single in Comment
-    True
-    >>> Comment in Comment.Multi
-    False
-
-This can be useful in :doc:`filters ` and if you write lexers on your
-own without using the base lexers.
-
-You can also split a token type into a hierarchy, and get the parent of it:
-
-.. sourcecode:: pycon
-
-    >>> String.split()
-    [Token, Token.Literal, Token.Literal.String]
-    >>> String.parent
-    Token.Literal
-
-In principle, you can create an unlimited number of token types but nobody can
-guarantee that a style would define style rules for a token type. Because of
-that, Pygments proposes some global token types defined in the
-`pygments.token.STANDARD_TYPES` dict.
-
-For some tokens aliases are already defined:
-
-.. sourcecode:: pycon
-
-    >>> from pygments.token import String
-    >>> String
-    Token.Literal.String
-
-Inside the :mod:`pygments.token` module the following aliases are defined:
-
-============= ============================ ====================================
-`Text`        `Token.Text`                 for any type of text data
-`Whitespace`  `Token.Text.Whitespace`      for specially highlighted whitespace
-`Error`       `Token.Error`                represents lexer errors
-`Other`       `Token.Other`                special token for data not
-                                           matched by a parser (e.g. HTML
-                                           markup in PHP code)
-`Keyword`     `Token.Keyword`              any kind of keywords
-`Name`        `Token.Name`                 variable/function names
-`Literal`     `Token.Literal`              Any literals
-`String`      `Token.Literal.String`       string literals
-`Number`      `Token.Literal.Number`       number literals
-`Operator`    `Token.Operator`             operators (``+``, ``not``...)
-`Punctuation` `Token.Punctuation`          punctuation (``[``, ``(``...)
-`Comment`     `Token.Comment`              any kind of comments
-`Generic`     `Token.Generic`              generic tokens (have a look at
-                                           the explanation below)
-============= ============================ ====================================
-
-The `Whitespace` token type is new in Pygments 0.8. It is used only by the
-`VisibleWhitespaceFilter` currently.
-
-Normally you just create token types using the already defined aliases. For each
-of those token aliases, a number of subtypes exists (excluding the special tokens
-`Token.Text`, `Token.Error` and `Token.Other`)
-
-The `is_token_subtype()` function in the `pygments.token` module can be used to
-test if a token type is a subtype of another (such as `Name.Tag` and `Name`).
-(This is the same as ``Name.Tag in Name``. The overloaded `in` operator was newly
-introduced in Pygments 0.7, the function still exists for backwards
-compatibility.)
-
-With Pygments 0.7, it's also possible to convert strings to token types (for example
-if you want to supply a token from the command line):
-
-.. sourcecode:: pycon
-
-    >>> from pygments.token import String, string_to_tokentype
-    >>> string_to_tokentype("String")
-    Token.Literal.String
-    >>> string_to_tokentype("Token.Literal.String")
-    Token.Literal.String
-    >>> string_to_tokentype(String)
-    Token.Literal.String
-
-
-Keyword Tokens
-==============
-
-`Keyword`
-    For any kind of keyword (especially if it doesn't match any of the
-    subtypes of course).
-
-`Keyword.Constant`
-    For keywords that are constants (e.g. ``None`` in future Python versions).
-
-`Keyword.Declaration`
-    For keywords used for variable declaration (e.g. ``var`` in some programming
-    languages like JavaScript).
-
-`Keyword.Namespace`
-    For keywords used for namespace declarations (e.g. ``import`` in Python and
-    Java and ``package`` in Java).
-
-`Keyword.Pseudo`
-    For keywords that aren't really keywords (e.g. ``None`` in old Python
-    versions).
-
-`Keyword.Reserved`
-    For reserved keywords.
-
-`Keyword.Type`
-    For builtin types that can't be used as identifiers (e.g. ``int``,
-    ``char`` etc. in C).
-
-
-Name Tokens
-===========
-
-`Name`
-    For any name (variable names, function names, classes).
-
-`Name.Attribute`
-    For all attributes (e.g. in HTML tags).
-
-`Name.Builtin`
-    Builtin names; names that are available in the global namespace.
-
-`Name.Builtin.Pseudo`
-    Builtin names that are implicit (e.g. ``self`` in Ruby, ``this`` in Java).
-
-`Name.Class`
-    Class names. Because no lexer can know if a name is a class or a function
-    or something else this token is meant for class declarations.
-
-`Name.Constant`
-    Token type for constants. In some languages you can recognise a token by the
-    way it's defined (the value after a ``const`` keyword for example). In
-    other languages constants are uppercase by definition (Ruby).
-
-`Name.Decorator`
-    Token type for decorators. Decorators are syntactic elements in the Python
-    language. Similar syntax elements exist in C# and Java.
-
-`Name.Entity`
-    Token type for special entities. (e.g. `` `` in HTML).
-
-`Name.Exception`
-    Token type for exception names (e.g. ``RuntimeError`` in Python). Some languages
-    define exceptions in the function signature (Java). You can highlight
-    the name of that exception using this token then.
-
-`Name.Function`
-    Token type for function names.
-
-`Name.Label`
-    Token type for label names (e.g. in languages that support ``goto``).
-
-`Name.Namespace`
-    Token type for namespaces. (e.g. import paths in Java/Python), names following
-    the ``module``/``namespace`` keyword in other languages.
-
-`Name.Other`
-    Other names. Normally unused.
-
-`Name.Tag`
-    Tag names (in HTML/XML markup or configuration files).
-
-`Name.Variable`
-    Token type for variables. Some languages have prefixes for variable names
-    (PHP, Ruby, Perl). You can highlight them using this token.
-
-`Name.Variable.Class`
-    same as `Name.Variable` but for class variables (also static variables).
-
-`Name.Variable.Global`
-    same as `Name.Variable` but for global variables (used in Ruby, for
-    example).
-
-`Name.Variable.Instance`
-    same as `Name.Variable` but for instance variables.
-
-
-Literals
-========
-
-`Literal`
-    For any literal (if not further defined).
-
-`Literal.Date`
-    for date literals (e.g. ``42d`` in Boo).
-
-
-`String`
-    For any string literal.
-
-`String.Backtick`
-    Token type for strings enclosed in backticks.
-
-`String.Char`
-    Token type for single characters (e.g. Java, C).

-
-`String.Interpol`
-    Token type for interpolated parts in strings (e.g. ``#{foo}`` in Ruby).
-
-`String.Other`
-    Token type for any other strings (for example ``%q{foo}`` string constructs
-    in Ruby).
-
-`String.Regex`
-    Token type for regular expression literals (e.g. ``/foo/`` in JavaScript).
-
-`String.Single`
-    Token type for single quoted strings.
-
-`String.Symbol`
-    Token type for symbols (e.g. ``:foo`` in LISP or Ruby).
-
-
-`Number`
-    Token type for any number literal.
-
-`Number.Bin`
-    Token type for binary literals (e.g. ``0b101010``).
-
-`Number.Float`
-    Token type for float literals (e.g. ``42.0``).
-
-`Number.Hex`
-    Token type for hexadecimal number literals (e.g. ``0xdeadbeef``).
-
-`Number.Integer`
-    Token type for integer literals (e.g. ``42``).
-
-`Number.Integer.Long`
-    Token type for long integer literals (e.g. ``42L`` in Python).
-
-`Number.Oct`
-    Token type for octal literals.

-
-
-Punctuation
-===========
-
-.. versionadded:: 0.7
-
-`Punctuation`
-    For any punctuation which is not an operator (e.g. ``[``, ``(``...)
-
-
-Comments
-========
-
-`Comment`
-    Token type for any comment.
-
-`Comment.Hashbang`
-    Token type for hashbang comments (i.e. first lines of files that start with
-     ``#!``).
-
-`Comment.Multiline`
-    Token type for multiline comments.
-
-`Comment.Preproc`
-    Token type for preprocessor comments (also ```.
-
-.. versionadded:: 0.7
-   The formatters now also accept an `outencoding` option which will override
-   the `encoding` option if given. This makes it possible to use a single
-   options dict with lexers and formatters, and still have different input and
-   output encodings.

-Pygments FAQ
-=============
-
-What is Pygments?
------------------
-
-Pygments is a syntax highlighting engine written in Python. That means, it will
-take source code (or other markup) in a supported language and output a
-processed version (in different formats) containing syntax highlighting markup.
-
-Its features include:
-
-* a wide range of common :doc:`languages and markup formats ` is supported
-* new languages and formats are added easily
-* a number of output formats is available, including:
-
-  - HTML
-  - ANSI sequences (console output)
-  - LaTeX
-  - RTF
-
-* it is usable as a command-line tool and as a library
-* parsing and formatting is fast
-
-Pygments is licensed under the BSD license.
-
-Where does the name Pygments come from?
----------------------------------------
-
-*Py* of course stands for Python, while *pigments* are used for coloring paint,
-and in this case, source code!
-
-What are the system requirements?
----------------------------------
-
-Pygments only needs a standard Python install, version 2.6 or higher or version
-3.3 or higher for Python 3. No additional libraries are needed.
-
-How can I use Pygments?
------------------------
-
-Pygments is usable as a command-line tool as well as a library.
-
-From the command-line, usage looks like this (assuming the pygmentize script is
-properly installed)::
-
-    pygmentize -f html /path/to/file.py
-
-This will print a HTML-highlighted version of /path/to/file.py to standard output.
-
-For a complete help, please run ``pygmentize -h``.
-
-Usage as a library is thoroughly demonstrated in the Documentation section.
-
-How do I make a new style?
---------------------------
-
-Please see the :doc:`documentation on styles `.
-
-How can I report a bug or suggest a feature?
---------------------------------------------
-
-Please report bugs and feature wishes in the tracker at Bitbucket.
-
-You can also e-mail the author or use IRC, see the contact details.
-
-I want this support for this language!
---------------------------------------
-
-Instead of waiting for others to include language support, why not write it
-yourself? All you have to know is :doc:`outlined in the docs
-`.
-
-Can I use Pygments for programming language processing?
--------------------------------------------------------
-
-The Pygments lexing machinery is quite powerful can be used to build lexers for
-basically all languages. However, parsing them is not possible, though some
-lexers go some steps in this direction in order to e.g. highlight function names
-differently.
-
-Also, error reporting is not the scope of Pygments. It focuses on correctly
-highlighting syntactically valid documents, not finding and compensating errors.
-
-Who uses Pygments?
-------------------
-
-This is an (incomplete) list of projects and sites known to use the Pygments highlighter.
-
-* `Wikipedia `_
-* `BitBucket `_, a Mercurial and Git hosting site
-* `The Sphinx documentation builder `_, for embedded source examples
-* `rst2pdf `_, a reStructuredText to PDF converter

-* `Diamanda `_, a Django powered wiki system with support for Pygments
-* `Progopedia `_ (`English `_),
-  an encyclopedia of programming languages
-* `Bruce `_, a reStructuredText presentation tool
-* `PIDA `_, a universal IDE written in Python
-* `BPython `_, a curses-based intelligent Python shell
-* `PuDB `_, a console Python debugger
-* `XWiki `_, a wiki-based development framework in Java, using Jython
-* `roux `_, a script for running R scripts
-  and creating beautiful output including graphs

-Welcome!
-========
-
-This is the home of Pygments.  It is a generic syntax highlighter suitable for
-use in code hosting, forums, wikis or other applications that need to prettify
-source code.  Highlights are:
-
-* a wide range of over 300 languages and other text formats is supported
-* special attention is paid to details that increase highlighting quality
-* support for new languages and formats are added easily; most languages use a
-  simple regex-based lexing mechanism
-* a number of output formats is available, among them HTML, RTF, LaTeX and ANSI
-  sequences
-* it is usable as a command-line tool and as a library
-* ... and it highlights even Perl 6!
-
-Read more in the :doc:`FAQ list ` or the :doc:`documentation `,
-or `download the latest release `_.

-
-Contribute
-----------
-
-Like every open-source project, we are always looking for volunteers to help us
-with programming. Python knowledge is required, but don't fear: Python is a very
-clear and easy to learn language.
-
-Development takes place on `Bitbucket
-`_, where the Mercurial
-repository, tickets and pull requests can be viewed.
-
-Our primary communication instrument is the IRC channel **#pocoo** on the
-Freenode network. To join it, let your IRC client connect to
-``irc.freenode.net`` and do ``/join #pocoo``.
-
-If you found a bug, just open a ticket in the Bitbucket tracker. Be sure to log
-in to be notified when the issue is fixed -- development is not fast-paced as
-the library is quite stable.  You can also send an e-mail to the developers, see
-below.
-
-The authors
------------
-
-Pygments is maintained by **Georg Brandl**, e-mail address *georg*\ *@*\ *python.org*.
-
-Many lexers and fixes have been contributed by **Armin Ronacher**, the rest of
-the `Pocoo `_ team and **Tim Hatch**.

-   correctness check is difficult and error prone and given that 1e10

-Informatik und Informationsgesellschaft I: Digitale Medien (32 214)
-Computer lassen ihre eigentliche Bestimmung durch Multimedia und Vernetzung erkennen: Es sind digitale Medien, die alle bisherigen Massen- und Kommunikationsmedien simulieren, kopieren oder ersetzen können. Die kurze Geschichte elektronischer Medien vom Telegramm bis zum Fernsehen wird so zur Vorgeschichte des Computers als Medium. Der Prozess der Mediatisierung der Rechnernetze soll in Technik, Theorie und Praxis untersucht werden. Das PR soll die Techniken der ortsverteilten und zeitversetzten Lehre an Hand praktischer Übungen vorführen und untersuchen.

-In this document, we'll take a tour of Python's features suitable for

-Introduction
-----------------------
-
-This section explains the basic concept of functional programming; if
-you're just interested in learning about Python language features,
-skip to the next section.
-
-Programming languages support decomposing problems in several different 
-ways:
-
-* Most programming languages are **procedural**: 
-  programs are lists of instructions that tell the computer what to
-  do with the program's input.
-  C, Pascal, and even Unix shells are procedural languages.
-
-* In **declarative** languages, you write a specification that describes 
-  the problem to be solved, and the language implementation figures out 
-  how to perform the computation efficiently.  SQL is the declarative 
-  language you're most likely to be familiar with; a SQL query describes
-  the data set you want to retrieve, and the SQL engine decides whether to 
-  scan tables or use indexes, which subclauses should be performed first,
-  etc.
-
-* **Object-oriented** programs manipulate  collections of objects.
-  Objects have internal state and support methods that query or modify
-  this internal state in some way. Smalltalk and Java are
-  object-oriented languages.  C++ and Python are languages that
-  support object-oriented programming, but don't force the use 
-  of object-oriented features.
-
-* **Functional** programming decomposes a problem into a set of functions.
-  Ideally, functions only take inputs and produce outputs, and don't have any 
-  internal state that affects the output produced for a given input.
-  Well-known functional languages include the ML family (Standard ML,
-  OCaml, and other variants) and Haskell.
-
-The designers of some computer languages have chosen one approach to 
-programming that's emphasized.  This often makes it difficult to
-write programs that use a different approach.  Other languages are
-multi-paradigm languages that support several different approaches.  Lisp,
-C++, and Python are multi-paradigm; you can write programs or
-libraries that are largely procedural, object-oriented, or functional
-in all of these languages.  In a large program, different sections
-might be written using different approaches; the GUI might be object-oriented
-while the processing logic is procedural or functional, for example.
-
-In a functional program, input flows through a set of functions. Each
-function operates on its input and produces some output.  Functional
-style frowns upon functions with side effects that modify internal
-state or make other changes that aren't visible in the function's
-return value.  Functions that have no side effects at all are 
-called **purely functional**.
-Avoiding side effects means not using data structures
-that get updated as a program runs; every function's output 
-must only depend on its input.
-
-Some languages are very strict about purity and don't even have
-assignment statements such as ``a=3`` or ``c = a + b``, but it's
-difficult to avoid all side effects.  Printing to the screen or
-writing to a disk file are side effects, for example.  For example, in
-Python a ``print`` statement or a ``time.sleep(1)`` both return no
-useful value; they're only called for their side effects of sending
-some text to the screen or pausing execution for a second.
-
-Python programs written in functional style usually won't go to the
-extreme of avoiding all I/O or all assignments; instead, they'll
-provide a functional-appearing interface but will use non-functional
-features internally.  For example, the implementation of a function
-will still use assignments to local variables, but won't modify global
-variables or have other side effects.
-
-Functional programming can be considered the opposite of
-object-oriented programming.  Objects are little capsules containing
-some internal state along with a collection of method calls that let
-you modify this state, and programs consist of making the right set of
-state changes.  Functional programming wants to avoid state changes as
-much as possible and works with data flowing between functions.  In
-Python you might combine the two approaches by writing functions that
-take and return instances representing objects in your application
-(e-mail messages, transactions, etc.).
-
-Functional design may seem like an odd constraint to work under.  Why
-should you avoid objects and side effects?  There are theoretical and
-practical advantages to the functional style:
-
-* Formal provability.
-* Modularity.
-* Composability.
-* Ease of debugging and testing.
-
-Formal provability
-''''''''''''''''''''''
-
-A theoretical benefit is that it's easier to construct a mathematical proof
-that a functional program is correct.
-
-For a long time researchers have been interested in finding ways to
-mathematically prove programs correct.  This is different from testing
-a program on numerous inputs and concluding that its output is usually
-correct, or reading a program's source code and concluding that the
-code looks right; the goal is instead a rigorous proof that a program
-produces the right result for all possible inputs.
-
-The technique used to prove programs correct is to write down 
-**invariants**, properties of the input data and of the program's 
-variables that are always true.  For each line of code, you then show 
-that if invariants X and Y are true **before** the line is executed, 
-the slightly different invariants X' and Y' are true **after**
-the line is executed.  This continues until you reach the end of the
-program, at which point the invariants should match the desired 
-conditions on the program's output.
-
-Functional programming's avoidance of assignments arose because 
-assignments are difficult to handle with this technique; 
-assignments can break invariants that were true before the assignment
-without producing any new invariants that can be propagated onward.
-
-Unfortunately, proving programs correct is largely impractical and not
-relevant to Python software. Even trivial programs require proofs that
-are several pages long; the proof of correctness for a moderately
-complicated program would be enormous, and few or none of the programs
-you use daily (the Python interpreter, your XML parser, your web
-browser) could be proven correct.  Even if you wrote down or generated
-a proof, there would then be the question of verifying the proof;
-maybe there's an error in it, and you wrongly believe you've proved
-the program correct.
-
-Modularity
-''''''''''''''''''''''
-
-A more practical benefit of functional programming is that it forces
-you to break apart your problem into small pieces.  Programs are more
-modular as a result.  It's easier to specify and write a small
-function that does one thing than a large function that performs a
-complicated transformation.  Small functions are also easier to read
-and to check for errors.
-
-
-Ease of debugging and testing 
-''''''''''''''''''''''''''''''''''
-
-Testing and debugging a functional-style program is easier.
-
-Debugging is simplified because functions are generally small and
-clearly specified.  When a program doesn't work, each function is an
-interface point where you can check that the data are correct.  You
-can look at the intermediate inputs and outputs to quickly isolate the
-function that's responsible for a bug.
-
-Testing is easier because each function is a potential subject for a
-unit test.  Functions don't depend on system state that needs to be
-replicated before running a test; instead you only have to synthesize
-the right input and then check that the output matches expectations.
-
-
-
-Composability
-''''''''''''''''''''''
-
-As you work on a functional-style program, you'll write a number of
-functions with varying inputs and outputs.  Some of these functions
-will be unavoidably specialized to a particular application, but
-others will be useful in a wide variety of programs.  For example, a
-function that takes a directory path and returns all the XML files in
-the directory, or a function that takes a filename and returns its
-contents, can be applied to many different situations.
-
-Over time you'll form a personal library of utilities.  Often you'll
-assemble new programs by arranging existing functions in a new
-configuration and writing a few functions specialized for the current
-task.
-
-
-
-Iterators
------------------------
-
-I'll start by looking at a Python language feature that's an important
-foundation for writing functional-style programs: iterators.
-
-An iterator is an object representing a stream of data; this object
-returns the data one element at a time.  A Python iterator must
-support a method called ``next()`` that takes no arguments and always
-returns the next element of the stream.  If there are no more elements
-in the stream, ``next()`` must raise the ``StopIteration`` exception.
-Iterators don't have to be finite, though; it's perfectly reasonable
-to write an iterator that produces an infinite stream of data.
-
-The built-in ``iter()`` function takes an arbitrary object and tries
-to return an iterator that will return the object's contents or
-elements, raising ``TypeError`` if the object doesn't support
-iteration.  Several of Python's built-in data types support iteration,
-the most common being lists and dictionaries.  An object is called 
-an **iterable** object if you can get an iterator for it.
-
-You can experiment with the iteration interface manually::
-
-    >>> L = [1,2,3]
-    >>> it = iter(L)
-    >>> print it
-    
-    >>> it.next()
-    1
-    >>> it.next()
-    2
-    >>> it.next()
-    3
-    >>> it.next()
-    Traceback (most recent call last):
-      File "", line 1, in ?
-    StopIteration
-    >>>      
-
-Python expects iterable objects in several different contexts, the 
-most important being the ``for`` statement.  In the statement ``for X in Y``,
-Y must be an iterator or some object for which ``iter()`` can create 
-an iterator.  These two statements are equivalent::
-
-        for i in iter(obj):
-            print i
-
-        for i in obj:
-            print i
-
-Iterators can be materialized as lists or tuples by using the
-``list()`` or ``tuple()`` constructor functions::
-
-    >>> L = [1,2,3]
-    >>> iterator = iter(L)
-    >>> t = tuple(iterator)
-    >>> t
-    (1, 2, 3)
-
-Sequence unpacking also supports iterators: if you know an iterator 
-will return N elements, you can unpack them into an N-tuple::
-
-    >>> L = [1,2,3]
-    >>> iterator = iter(L)
-    >>> a,b,c = iterator
-    >>> a,b,c
-    (1, 2, 3)
-
-Built-in functions such as ``max()`` and ``min()`` can take a single
-iterator argument and will return the largest or smallest element.
-The ``"in"`` and ``"not in"`` operators also support iterators: ``X in
-iterator`` is true if X is found in the stream returned by the
-iterator.  You'll run into obvious problems if the iterator is
-infinite; ``max()``, ``min()``, and ``"not in"`` will never return, and
-if the element X never appears in the stream, the ``"in"`` operator
-won't return either.
-
-Note that you can only go forward in an iterator; there's no way to
-get the previous element, reset the iterator, or make a copy of it.
-Iterator objects can optionally provide these additional capabilities,
-but the iterator protocol only specifies the ``next()`` method.
-Functions may therefore consume all of the iterator's output, and if
-you need to do something different with the same stream, you'll have
-to create a new iterator.
-
-
-
-Data Types That Support Iterators
-'''''''''''''''''''''''''''''''''''
-
-We've already seen how lists and tuples support iterators.  In fact,
-any Python sequence type, such as strings, will automatically support
-creation of an iterator.
-
-Calling ``iter()`` on a dictionary returns an iterator that will loop
-over the dictionary's keys::
-
-    >>> m = {'Jan': 1, 'Feb': 2, 'Mar': 3, 'Apr': 4, 'May': 5, 'Jun': 6,
-    ...      'Jul': 7, 'Aug': 8, 'Sep': 9, 'Oct': 10, 'Nov': 11, 'Dec': 12}
-    >>> for key in m:
-    ...     print key, m[key]
-    Mar 3
-    Feb 2
-    Aug 8
-    Sep 9
-    May 5
-    Jun 6
-    Jul 7
-    Jan 1
-    Apr 4
-    Nov 11
-    Dec 12
-    Oct 10
-
-Note that the order is essentially random, because it's based on the
-hash ordering of the objects in the dictionary.
-
-Applying ``iter()`` to a dictionary always loops over the keys, but
-dictionaries have methods that return other iterators.  If you want to
-iterate over keys, values, or key/value pairs, you can explicitly call
-the ``iterkeys()``, ``itervalues()``, or ``iteritems()`` methods to
-get an appropriate iterator.
-
-The ``dict()`` constructor can accept an iterator that returns a
-finite stream of ``(key, value)`` tuples::
-
-    >>> L = [('Italy', 'Rome'), ('France', 'Paris'), ('US', 'Washington DC')]
-    >>> dict(iter(L))
-    {'Italy': 'Rome', 'US': 'Washington DC', 'France': 'Paris'}
-
-Files also support iteration by calling the ``readline()``
-method until there are no more lines in the file.  This means you can
-read each line of a file like this::
-
-    for line in file:
-        # do something for each line
-        ...
-
-Sets can take their contents from an iterable and let you iterate over
-the set's elements::
-
-    S = set((2, 3, 5, 7, 11, 13))
-    for i in S:
-        print i
-
-
-
-Generator expressions and list comprehensions
-----------------------------------------------------
-
-Two common operations on an iterator's output are 1) performing some
-operation for every element, 2) selecting a subset of elements that
-meet some condition.  For example, given a list of strings, you might
-want to strip off trailing whitespace from each line or extract all
-the strings containing a given substring.
-
-List comprehensions and generator expressions (short form: "listcomps"
-and "genexps") are a concise notation for such operations, borrowed
-from the functional programming language Haskell
-(http://www.haskell.org).  You can strip all the whitespace from a
-stream of strings with the following code::
-
-        line_list = ['  line 1\n', 'line 2  \n', ...]
-
-        # Generator expression -- returns iterator
-        stripped_iter = (line.strip() for line in line_list)
-
-        # List comprehension -- returns list
-        stripped_list = [line.strip() for line in line_list]
-
-You can select only certain elements by adding an ``"if"`` condition::
-
-        stripped_list = [line.strip() for line in line_list
-                         if line != ""]
-
-With a list comprehension, you get back a Python list;
-``stripped_list`` is a list containing the resulting lines, not an
-iterator.  Generator expressions return an iterator that computes the
-values as necessary, not needing to materialize all the values at
-once.  This means that list comprehensions aren't useful if you're
-working with iterators that return an infinite stream or a very large
-amount of data.  Generator expressions are preferable in these
-situations.
-
-Generator expressions are surrounded by parentheses ("()") and list
-comprehensions are surrounded by square brackets ("[]").  Generator
-expressions have the form::
-
-    ( expression for expr in sequence1 
-                 if condition1
-                 for expr2 in sequence2
-                 if condition2
-                 for expr3 in sequence3 ...
-                 if condition3
-                 for exprN in sequenceN
-                 if conditionN )
-
-Again, for a list comprehension only the outside brackets are
-different (square brackets instead of parentheses).
-
-The elements of the generated output will be the successive values of
-``expression``.  The ``if`` clauses are all optional; if present,
-``expression`` is only evaluated and added to the result when
-``condition`` is true.
-
-Generator expressions always have to be written inside parentheses,
-but the parentheses signalling a function call also count.  If you
-want to create an iterator that will be immediately passed to a
-function you can write::
-
-        obj_total = sum(obj.count for obj in list_all_objects())
-
-The ``for...in`` clauses contain the sequences to be iterated over.
-The sequences do not have to be the same length, because they are
-iterated over from left to right, **not** in parallel.  For each
-element in ``sequence1``, ``sequence2`` is looped over from the
-beginning.  ``sequence3``  is then looped over for each 
-resulting pair of elements from ``sequence1`` and ``sequence2``.
-
-To put it another way, a list comprehension or generator expression is
-equivalent to the following Python code::
-
-    for expr1 in sequence1:
-        if not (condition1):
-            continue   # Skip this element
-        for expr2 in sequence2:
-            if not (condition2):
-                continue    # Skip this element
-            ...
-            for exprN in sequenceN:
-                 if not (conditionN):
-                     continue   # Skip this element
-
-                 # Output the value of 
-                 # the expression.
-
-This means that when there are multiple ``for...in`` clauses but no
-``if`` clauses, the length of the resulting output will be equal to
-the product of the lengths of all the sequences.  If you have two
-lists of length 3, the output list is 9 elements long::
-
-    seq1 = 'abc'
-    seq2 = (1,2,3)
-    >>> [ (x,y) for x in seq1 for y in seq2]
-    [('a', 1), ('a', 2), ('a', 3), 
-     ('b', 1), ('b', 2), ('b', 3), 
-     ('c', 1), ('c', 2), ('c', 3)]
-
-To avoid introducing an ambiguity into Python's grammar, if
-``expression`` is creating a tuple, it must be surrounded with
-parentheses.  The first list comprehension below is a syntax error,
-while the second one is correct::
-
-    # Syntax error
-    [ x,y for x in seq1 for y in seq2]
-    # Correct
-    [ (x,y) for x in seq1 for y in seq2]
-
-
-Generators
------------------------
-
-Generators are a special class of functions that simplify the task of
-writing iterators.  Regular functions compute a value and return it,
-but generators return an iterator that returns a stream of values.
-
-You're doubtless familiar with how regular function calls work in
-Python or C.  When you call a function, it gets a private namespace
-where its local variables are created.  When the function reaches a
-``return`` statement, the local variables are destroyed and the
-value is returned to the caller.  A later call to the same function
-creates a new private namespace and a fresh set of local
-variables. But, what if the local variables weren't thrown away on
-exiting a function?  What if you could later resume the function where
-it left off?  This is what generators provide; they can be thought of
-as resumable functions.
-
-Here's the simplest example of a generator function::
-
-    def generate_ints(N):
-        for i in range(N):
-            yield i
-
-Any function containing a ``yield`` keyword is a generator function;
-this is detected by Python's bytecode compiler which compiles the
-function specially as a result.
-
-When you call a generator function, it doesn't return a single value;
-instead it returns a generator object that supports the iterator
-protocol.  On executing the ``yield`` expression, the generator
-outputs the value of ``i``, similar to a ``return``
-statement.  The big difference between ``yield`` and a
-``return`` statement is that on reaching a ``yield`` the
-generator's state of execution is suspended and local variables are
-preserved.  On the next call to the generator's ``.next()`` method,
-the function will resume executing.  
-
-Here's a sample usage of the ``generate_ints()`` generator::
-
-    >>> gen = generate_ints(3)
-    >>> gen
-    
-    >>> gen.next()
-    0
-    >>> gen.next()
-    1
-    >>> gen.next()
-    2
-    >>> gen.next()
-    Traceback (most recent call last):
-      File "stdin", line 1, in ?
-      File "stdin", line 2, in generate_ints
-    StopIteration
-
-You could equally write ``for i in generate_ints(5)``, or
-``a,b,c = generate_ints(3)``.
-
-Inside a generator function, the ``return`` statement can only be used
-without a value, and signals the end of the procession of values;
-after executing a ``return`` the generator cannot return any further
-values.  ``return`` with a value, such as ``return 5``, is a syntax
-error inside a generator function.  The end of the generator's results
-can also be indicated by raising ``StopIteration`` manually, or by
-just letting the flow of execution fall off the bottom of the
-function.
-
-You could achieve the effect of generators manually by writing your
-own class and storing all the local variables of the generator as
-instance variables.  For example, returning a list of integers could
-be done by setting ``self.count`` to 0, and having the
-``next()`` method increment ``self.count`` and return it.
-However, for a moderately complicated generator, writing a
-corresponding class can be much messier.
-
-The test suite included with Python's library, ``test_generators.py``,
-contains a number of more interesting examples.  Here's one generator
-that implements an in-order traversal of a tree using generators
-recursively.
-
-::
-
-    # A recursive generator that generates Tree leaves in in-order.
-    def inorder(t):
-        if t:
-            for x in inorder(t.left):
-                yield x
-
-            yield t.label
-
-            for x in inorder(t.right):
-                yield x
-
-Two other examples in ``test_generators.py`` produce
-solutions for the N-Queens problem (placing N queens on an NxN
-chess board so that no queen threatens another) and the Knight's Tour
-(finding a route that takes a knight to every square of an NxN chessboard
-without visiting any square twice).
-
-
-
-Passing values into a generator
-''''''''''''''''''''''''''''''''''''''''''''''
-
-In Python 2.4 and earlier, generators only produced output.  Once a
-generator's code was invoked to create an iterator, there was no way to
-pass any new information into the function when its execution is
-resumed.  You could hack together this ability by making the
-generator look at a global variable or by passing in some mutable object
-that callers then modify, but these approaches are messy.
-
-In Python 2.5 there's a simple way to pass values into a generator.
-``yield`` became an expression, returning a value that can be assigned
-to a variable or otherwise operated on::
-
-    val = (yield i)
-
-I recommend that you **always** put parentheses around a ``yield``
-expression when you're doing something with the returned value, as in
-the above example.  The parentheses aren't always necessary, but it's
-easier to always add them instead of having to remember when they're
-needed.
-
-(PEP 342 explains the exact rules, which are that a
-``yield``-expression must always be parenthesized except when it
-occurs at the top-level expression on the right-hand side of an
-assignment.  This means you can write ``val = yield i`` but have to
-use parentheses when there's an operation, as in ``val = (yield i)
-+ 12``.)
-
-Values are sent into a generator by calling its
-``send(value)`` method.  This method resumes the 
-generator's code and the ``yield`` expression returns the specified
-value.  If the regular ``next()`` method is called, the
-``yield`` returns ``None``.
-
-Here's a simple counter that increments by 1 and allows changing the
-value of the internal counter.
-
-::
-
-    def counter (maximum):
-        i = 0
-        while i < maximum:
-            val = (yield i)
-            # If value provided, change counter
-            if val is not None:
-                i = val
-            else:
-                i += 1
-
-And here's an example of changing the counter:
-
-    >>> it = counter(10)
-    >>> print it.next()
-    0
-    >>> print it.next()
-    1
-    >>> print it.send(8)
-    8
-    >>> print it.next()
-    9
-    >>> print it.next()
-    Traceback (most recent call last):
-      File ``t.py'', line 15, in ?
-        print it.next()
-    StopIteration
-
-Because ``yield`` will often be returning ``None``, you
-should always check for this case.  Don't just use its value in
-expressions unless you're sure that the ``send()`` method
-will be the only method used resume your generator function.
-
-In addition to ``send()``, there are two other new methods on
-generators:
-
-* ``throw(type, value=None, traceback=None)`` is used to raise an exception inside the
-  generator; the exception is raised by the ``yield`` expression
-  where the generator's execution is paused.
-
-* ``close()`` raises a ``GeneratorExit``
-  exception inside the generator to terminate the iteration.  
-  On receiving this
-  exception, the generator's code must either raise
-  ``GeneratorExit`` or ``StopIteration``; catching the 
-  exception and doing anything else is illegal and will trigger
-  a ``RuntimeError``.  ``close()`` will also be called by 
-  Python's garbage collector when the generator is garbage-collected.
-
-  If you need to run cleanup code when a ``GeneratorExit`` occurs,
-  I suggest using a ``try: ... finally:`` suite instead of 
-  catching ``GeneratorExit``.
-
-The cumulative effect of these changes is to turn generators from
-one-way producers of information into both producers and consumers.
-
-Generators also become **coroutines**, a more generalized form of
-subroutines.  Subroutines are entered at one point and exited at
-another point (the top of the function, and a ``return``
-statement), but coroutines can be entered, exited, and resumed at
-many different points (the ``yield`` statements).  
-
-
-Built-in functions
-----------------------------------------------
-
-Let's look in more detail at built-in functions often used with iterators.
-
-Two Python's built-in functions, ``map()`` and ``filter()``, are
-somewhat obsolete; they duplicate the features of list comprehensions
-but return actual lists instead of iterators.  
-
-``map(f, iterA, iterB, ...)`` returns a list containing ``f(iterA[0],
-iterB[0]), f(iterA[1], iterB[1]), f(iterA[2], iterB[2]), ...``.  
-
-::
-
-    def upper(s):
-        return s.upper()
-    map(upper, ['sentence', 'fragment']) =>
-      ['SENTENCE', 'FRAGMENT']
-
-    [upper(s) for s in ['sentence', 'fragment']] =>
-      ['SENTENCE', 'FRAGMENT']
-
-As shown above, you can achieve the same effect with a list
-comprehension.  The ``itertools.imap()`` function does the same thing
-but can handle infinite iterators; it'll be discussed later, in the section on 
-the ``itertools`` module.
-
-``filter(predicate, iter)`` returns a list 
-that contains all the sequence elements that meet a certain condition,
-and is similarly duplicated by list comprehensions.
-A **predicate** is a function that returns the truth value of
-some condition; for use with ``filter()``, the predicate must take a 
-single value.  
-
-::
-
-    def is_even(x):
-        return (x % 2) == 0
-
-    filter(is_even, range(10)) =>
-      [0, 2, 4, 6, 8]
-
-This can also be written as a list comprehension::
-
-    >>> [x for x in range(10) if is_even(x)]
-    [0, 2, 4, 6, 8]
-
-``filter()`` also has a counterpart in the ``itertools`` module,
-``itertools.ifilter()``, that returns an iterator and 
-can therefore handle infinite sequences just as ``itertools.imap()`` can.
-
-``reduce(func, iter, [initial_value])`` doesn't have a counterpart in
-the ``itertools`` module because it cumulatively performs an operation
-on all the iterable's elements and therefore can't be applied to
-infinite iterables.  ``func`` must be a function that takes two elements
-and returns a single value.  ``reduce()`` takes the first two elements
-A and B returned by the iterator and calculates ``func(A, B)``.  It
-then requests the third element, C, calculates ``func(func(A, B),
-C)``, combines this result with the fourth element returned, and
-continues until the iterable is exhausted.  If the iterable returns no
-values at all, a ``TypeError`` exception is raised.  If the initial
-value is supplied, it's used as a starting point and
-``func(initial_value, A)`` is the first calculation.
-
-::
-
-    import operator
-    reduce(operator.concat, ['A', 'BB', 'C']) =>
-      'ABBC'
-    reduce(operator.concat, []) =>
-      TypeError: reduce() of empty sequence with no initial value
-    reduce(operator.mul, [1,2,3], 1) =>
-      6
-    reduce(operator.mul, [], 1) =>
-      1
-
-If you use ``operator.add`` with ``reduce()``, you'll add up all the 
-elements of the iterable.  This case is so common that there's a special
-built-in called ``sum()`` to compute it::
-
-    reduce(operator.add, [1,2,3,4], 0) =>
-      10
-    sum([1,2,3,4]) =>
-      10
-    sum([]) =>
-      0
-
-For many uses of ``reduce()``, though, it can be clearer to just write
-the obvious ``for`` loop::
-
-    # Instead of:
-    product = reduce(operator.mul, [1,2,3], 1)
-
-    # You can write:
-    product = 1
-    for i in [1,2,3]:
-        product *= i
-
-
-``enumerate(iter)`` counts off the elements in the iterable, returning
-2-tuples containing the count and each element.
-
-::
-
-    enumerate(['subject', 'verb', 'object']) =>
-      (0, 'subject'), (1, 'verb'), (2, 'object')
-
-``enumerate()`` is often used when looping through a list 
-and recording the indexes at which certain conditions are met::
-
-    f = open('data.txt', 'r')
-    for i, line in enumerate(f):
-        if line.strip() == '':
-            print 'Blank line at line #%i' % i
-
-``sorted(iterable, [cmp=None], [key=None], [reverse=False)`` 
-collects all the elements of the iterable into a list, sorts 
-the list, and returns the sorted result.  The ``cmp``, ``key``, 
-and ``reverse`` arguments are passed through to the 
-constructed list's ``.sort()`` method.
-
-::
-
-    import random
-    # Generate 8 random numbers between [0, 10000)
-    rand_list = random.sample(range(10000), 8)
-    rand_list =>
-      [769, 7953, 9828, 6431, 8442, 9878, 6213, 2207]
-    sorted(rand_list) =>
-      [769, 2207, 6213, 6431, 7953, 8442, 9828, 9878]
-    sorted(rand_list, reverse=True) =>
-      [9878, 9828, 8442, 7953, 6431, 6213, 2207, 769]
-
-(For a more detailed discussion of sorting, see the Sorting mini-HOWTO
-in the Python wiki at http://wiki.python.org/moin/HowTo/Sorting.)
-
-The ``any(iter)`` and ``all(iter)`` built-ins look at 
-the truth values of an iterable's contents.  ``any()`` returns 
-True if any element in the iterable is a true value, and ``all()`` 
-returns True if all of the elements are true values::
-
-    any([0,1,0]) =>
-      True
-    any([0,0,0]) =>
-      False
-    any([1,1,1]) =>
-      True
-    all([0,1,0]) =>
-      False
-    all([0,0,0]) => 
-      False
-    all([1,1,1]) =>
-      True
-
-
-Small functions and the lambda statement
-----------------------------------------------
-
-When writing functional-style programs, you'll often need little
-functions that act as predicates or that combine elements in some way.
-
-If there's a Python built-in or a module function that's suitable, you
-don't need to define a new function at all::
-
-        stripped_lines = [line.strip() for line in lines]
-        existing_files = filter(os.path.exists, file_list)
-
-If the function you need doesn't exist, you need to write it.  One way
-to write small functions is to use the ``lambda`` statement.  ``lambda``
-takes a number of parameters and an expression combining these parameters,
-and creates a small function that returns the value of the expression::
-
-        lowercase = lambda x: x.lower()
-
-        print_assign = lambda name, value: name + '=' + str(value)
-
-        adder = lambda x, y: x+y
-
-An alternative is to just use the ``def`` statement and define a
-function in the usual way::
-
-        def lowercase(x):
-            return x.lower()
-
-        def print_assign(name, value):
-            return name + '=' + str(value)
-
-        def adder(x,y):
-            return x + y
-
-Which alternative is preferable?  That's a style question; my usual
-course is to avoid using ``lambda``.
-
-One reason for my preference is that ``lambda`` is quite limited in
-the functions it can define.  The result has to be computable as a
-single expression, which means you can't have multiway
-``if... elif... else`` comparisons or ``try... except`` statements.
-If you try to do too much in a ``lambda`` statement, you'll end up
-with an overly complicated expression that's hard to read.  Quick,
-what's the following code doing?
-
-::
-
-    total = reduce(lambda a, b: (0, a[1] + b[1]), items)[1]
-
-You can figure it out, but it takes time to disentangle the expression
-to figure out what's going on.  Using a short nested
-``def`` statements makes things a little bit better::
-
-    def combine (a, b):
-        return 0, a[1] + b[1]
-
-    total = reduce(combine, items)[1]
-
-But it would be best of all if I had simply used a ``for`` loop::
-
-     total = 0
-     for a, b in items:
-         total += b
-
-Or the ``sum()`` built-in and a generator expression::
-
-     total = sum(b for a,b in items)
-
-Many uses of ``reduce()`` are clearer when written as ``for`` loops.
-
-Fredrik Lundh once suggested the following set of rules for refactoring 
-uses of ``lambda``:
-
-1) Write a lambda function.
-2) Write a comment explaining what the heck that lambda does.
-3) Study the comment for a while, and think of a name that captures
-   the essence of the comment.
-4) Convert the lambda to a def statement, using that name.
-5) Remove the comment.
-
-I really like these rules, but you're free to disagree that this 
-lambda-free style is better.
-
-
-The itertools module
------------------------
-
-The ``itertools`` module contains a number of commonly-used iterators
-as well as functions for combining several iterators.  This section
-will introduce the module's contents by showing small examples.
-
-The module's functions fall into a few broad classes:
-
-* Functions that create a new iterator based on an existing iterator.
-* Functions for treating an iterator's elements as function arguments.
-* Functions for selecting portions of an iterator's output.
-* A function for grouping an iterator's output.
-
-Creating new iterators
-''''''''''''''''''''''
-
-``itertools.count(n)`` returns an infinite stream of
-integers, increasing by 1 each time.  You can optionally supply the
-starting number, which defaults to 0::
-
-        itertools.count() =>
-          0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...
-        itertools.count(10) =>
-          10, 11, 12, 13, 14, 15, 16, 17, 18, 19, ...
-
-``itertools.cycle(iter)`` saves a copy of the contents of a provided
-iterable and returns a new iterator that returns its elements from
-first to last.  The new iterator will repeat these elements infinitely.
-
-::
-
-        itertools.cycle([1,2,3,4,5]) =>
-          1, 2, 3, 4, 5, 1, 2, 3, 4, 5, ...
-
-``itertools.repeat(elem, [n])`` returns the provided element ``n``
-times, or returns the element endlessly if ``n`` is not provided.
-
-::
-
-    itertools.repeat('abc') =>
-      abc, abc, abc, abc, abc, abc, abc, abc, abc, abc, ...
-    itertools.repeat('abc', 5) =>
-      abc, abc, abc, abc, abc
-
-``itertools.chain(iterA, iterB, ...)`` takes an arbitrary number of
-iterables as input, and returns all the elements of the first
-iterator, then all the elements of the second, and so on, until all of
-the iterables have been exhausted.
-
-::
-
-    itertools.chain(['a', 'b', 'c'], (1, 2, 3)) =>
-      a, b, c, 1, 2, 3
-
-``itertools.izip(iterA, iterB, ...)`` takes one element from each iterable
-and returns them in a tuple::
-
-    itertools.izip(['a', 'b', 'c'], (1, 2, 3)) =>
-      ('a', 1), ('b', 2), ('c', 3)
-
-It's similiar to the built-in ``zip()`` function, but doesn't
-construct an in-memory list and exhaust all the input iterators before
-returning; instead tuples are constructed and returned only if they're
-requested.  (The technical term for this behaviour is 
-`lazy evaluation `__.)
-
-This iterator is intended to be used with iterables that are all of
-the same length.  If the iterables are of different lengths, the
-resulting stream will be the same length as the shortest iterable.
-
-::
-
-    itertools.izip(['a', 'b'], (1, 2, 3)) =>
-      ('a', 1), ('b', 2)
-
-You should avoid doing this, though, because an element may be taken
-from the longer iterators and discarded.  This means you can't go on
-to use the iterators further because you risk skipping a discarded
-element.
-
-``itertools.islice(iter, [start], stop, [step])`` returns a stream
-that's a slice of the iterator.  With a single ``stop`` argument, 
-it will return the first ``stop``
-elements.  If you supply a starting index, you'll get ``stop-start``
-elements, and if you supply a value for ``step``, elements will be
-skipped accordingly.  Unlike Python's string and list slicing, you
-can't use negative values for ``start``, ``stop``, or ``step``.
-
-::
-
-    itertools.islice(range(10), 8) =>
-      0, 1, 2, 3, 4, 5, 6, 7
-    itertools.islice(range(10), 2, 8) =>
-      2, 3, 4, 5, 6, 7
-    itertools.islice(range(10), 2, 8, 2) =>
-      2, 4, 6
-
-``itertools.tee(iter, [n])`` replicates an iterator; it returns ``n``
-independent iterators that will all return the contents of the source
-iterator.  If you don't supply a value for ``n``, the default is 2.
-Replicating iterators requires saving some of the contents of the source
-iterator, so this can consume significant memory if the iterator is large
-and one of the new iterators is consumed more than the others.
-
-::
-
-        itertools.tee( itertools.count() ) =>
-           iterA, iterB
-
-        where iterA ->
-           0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...
-
-        and   iterB ->
-           0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...
-
-
-Calling functions on elements
-'''''''''''''''''''''''''''''
-
-Two functions are used for calling other functions on the contents of an
-iterable.
-
-``itertools.imap(f, iterA, iterB, ...)`` returns 
-a stream containing ``f(iterA[0], iterB[0]), f(iterA[1], iterB[1]),
-f(iterA[2], iterB[2]), ...``::
-
-    itertools.imap(operator.add, [5, 6, 5], [1, 2, 3]) =>
-      6, 8, 8
-
-The ``operator`` module contains a set of functions 
-corresponding to Python's operators.  Some examples are 
-``operator.add(a, b)`` (adds two values), 
-``operator.ne(a, b)`` (same as ``a!=b``),
-and 
-``operator.attrgetter('id')`` (returns a callable that
-fetches the ``"id"`` attribute).
-
-``itertools.starmap(func, iter)`` assumes that the iterable will 
-return a stream of tuples, and calls ``f()`` using these tuples as the 
-arguments::
-
-    itertools.starmap(os.path.join, 
-                      [('/usr', 'bin', 'java'), ('/bin', 'python'),
-                       ('/usr', 'bin', 'perl'),('/usr', 'bin', 'ruby')])
-    =>
-      /usr/bin/java, /bin/python, /usr/bin/perl, /usr/bin/ruby
-
-
-Selecting elements
-''''''''''''''''''
-
-Another group of functions chooses a subset of an iterator's elements
-based on a predicate.
-
-``itertools.ifilter(predicate, iter)`` returns all the elements for
-which the predicate returns true::
-
-    def is_even(x):
-        return (x % 2) == 0
-
-    itertools.ifilter(is_even, itertools.count()) =>
-      0, 2, 4, 6, 8, 10, 12, 14, ...
-
-``itertools.ifilterfalse(predicate, iter)`` is the opposite, 
-returning all elements for which the predicate returns false::
-
-    itertools.ifilterfalse(is_even, itertools.count()) =>
-      1, 3, 5, 7, 9, 11, 13, 15, ...
-
-``itertools.takewhile(predicate, iter)`` returns elements for as long
-as the predicate returns true.  Once the predicate returns false, 
-the iterator will signal the end of its results.
-
-::
-
-    def less_than_10(x):
-        return (x < 10)
-
-    itertools.takewhile(less_than_10, itertools.count()) =>
-      0, 1, 2, 3, 4, 5, 6, 7, 8, 9
-
-    itertools.takewhile(is_even, itertools.count()) =>
-      0
-
-``itertools.dropwhile(predicate, iter)`` discards elements while the
-predicate returns true, and then returns the rest of the iterable's
-results.
-
-::
-
-    itertools.dropwhile(less_than_10, itertools.count()) =>
-      10, 11, 12, 13, 14, 15, 16, 17, 18, 19, ...
-
-    itertools.dropwhile(is_even, itertools.count()) =>
-      1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...
-
-
-Grouping elements
-'''''''''''''''''
-
-The last function I'll discuss, ``itertools.groupby(iter,
-key_func=None)``, is the most complicated.  ``key_func(elem)`` is a
-function that can compute a key value for each element returned by the
-iterable.  If you don't supply a key function, the key is simply each
-element itself.
-
-``groupby()`` collects all the consecutive elements from the
-underlying iterable that have the same key value, and returns a stream
-of 2-tuples containing a key value and an iterator for the elements
-with that key.  
-
-::
-
-    city_list = [('Decatur', 'AL'), ('Huntsville', 'AL'), ('Selma', 'AL'), 
-                 ('Anchorage', 'AK'), ('Nome', 'AK'),
-                 ('Flagstaff', 'AZ'), ('Phoenix', 'AZ'), ('Tucson', 'AZ'), 
-                 ...
-                ]
-
-    def get_state ((city, state)):
-        return state
-
-    itertools.groupby(city_list, get_state) =>
-      ('AL', iterator-1),
-      ('AK', iterator-2),
-      ('AZ', iterator-3), ...
-
-    where
-    iterator-1 =>
-      ('Decatur', 'AL'), ('Huntsville', 'AL'), ('Selma', 'AL')
-    iterator-2 => 
-      ('Anchorage', 'AK'), ('Nome', 'AK')
-    iterator-3 =>
-      ('Flagstaff', 'AZ'), ('Phoenix', 'AZ'), ('Tucson', 'AZ')
-
-``groupby()`` assumes that the underlying iterable's contents will
-already be sorted based on the key.  Note that the returned iterators
-also use the underlying iterable, so you have to consume the results
-of iterator-1 before requesting iterator-2 and its corresponding key.
-
-
-The functools module
-----------------------------------------------
-
-The ``functools`` module in Python 2.5 contains some higher-order
-functions.  A **higher-order function** takes one or more functions as
-input and returns a new function.  The most useful tool in this module
-is the ``partial()`` function.
-
-For programs written in a functional style, you'll sometimes want to
-construct variants of existing functions that have some of the
-parameters filled in.  Consider a Python function ``f(a, b, c)``; you
-may wish to create a new function ``g(b, c)`` that's equivalent to
-``f(1, b, c)``; you're filling in a value for one of ``f()``'s parameters.  
-This is called "partial function application".
-
-The constructor for ``partial`` takes the arguments ``(function, arg1,
-arg2, ... kwarg1=value1, kwarg2=value2)``.  The resulting object is
-callable, so you can just call it to invoke ``function`` with the
-filled-in arguments.
-
-Here's a small but realistic example::
-
-    import functools
-
-    def log (message, subsystem):
-        "Write the contents of 'message' to the specified subsystem."
-        print '%s: %s' % (subsystem, message)
-        ...
-
-    server_log = functools.partial(log, subsystem='server')
-    server_log('Unable to open socket')
-
-
-The operator module
--------------------
-
-The ``operator`` module was mentioned earlier.  It contains a set of
-functions corresponding to Python's operators.  These functions 
-are often useful in functional-style code because they save you 
-from writing trivial functions that perform a single operation.
-
-Some of the functions in this module are:
-
-* Math operations: ``add()``, ``sub()``, ``mul()``, ``div()``, ``floordiv()``,
-  ``abs()``, ...

-The functional module
----------------------
-
-Collin Winter's `functional module `__ 
-provides a number of more
-advanced tools for functional programming. It also reimplements
-several Python built-ins, trying to make them more intuitive to those
-used to functional programming in other languages.
-
-This section contains an introduction to some of the most important
-functions in ``functional``; full documentation can be found at `the
-project's website `__.
-
-``compose(outer, inner, unpack=False)``
-
-The ``compose()`` function implements function composition.
-In other words, it returns a wrapper around the ``outer`` and ``inner`` callables, such
-that the return value from ``inner`` is fed directly to ``outer``.  That is,
-
-::
-
-        >>> def add(a, b):
-        ...     return a + b
-        ...
-        >>> def double(a):
-        ...     return 2 * a
-        ...
-        >>> compose(double, add)(5, 6)
-        22
-
-is equivalent to
-
-::
-
-        >>> double(add(5, 6))
-        22
-                    
-The ``unpack`` keyword is provided to work around the fact that Python functions are not always
-`fully curried `__.
-By default, it is expected that the ``inner`` function will return a single object and that the ``outer``
-function will take a single argument. Setting the ``unpack`` argument causes ``compose`` to expect a
-tuple from ``inner`` which will be expanded before being passed to ``outer``. Put simply,
-
-::
-
-        compose(f, g)(5, 6)
-                    
-is equivalent to::
-
-        f(g(5, 6))
-                    
-while
-
-::
-
-        compose(f, g, unpack=True)(5, 6)
-                    
-is equivalent to::
-
-        f(*g(5, 6))
-
-Even though ``compose()`` only accepts two functions, it's trivial to
-build up a version that will compose any number of functions. We'll
-use ``reduce()``, ``compose()`` and ``partial()`` (the last of which
-is provided by both ``functional`` and ``functools``).
-
-::
-
-        from functional import compose, partial
-        
-        multi_compose = partial(reduce, compose)
-        
-    
-We can also use ``map()``, ``compose()`` and ``partial()`` to craft a
-version of ``"".join(...)`` that converts its arguments to string::
-
-        from functional import compose, partial
-        
-        join = compose("".join, partial(map, str))
-
-
-``flip(func)``
-                    
-``flip()`` wraps the callable in ``func`` and  
-causes it to receive its non-keyword arguments in reverse order.
-
-::
-
-        >>> def triple(a, b, c):
-        ...     return (a, b, c)
-        ...
-        >>> triple(5, 6, 7)
-        (5, 6, 7)
-        >>>
-        >>> flipped_triple = flip(triple)
-        >>> flipped_triple(5, 6, 7)
-        (7, 6, 5)
-
-``foldl(func, start, iterable)``
-                    
-``foldl()`` takes a binary function, a starting value (usually some kind of 'zero'), and an iterable.
-The function is applied to the starting value and the first element of the list, then the result of
-that and the second element of the list, then the result of that and the third element of the list,
-and so on.
-
-This means that a call such as::
-
-        foldl(f, 0, [1, 2, 3])
-
-is equivalent to::
-
-        f(f(f(0, 1), 2), 3)
-
-    
-``foldl()`` is roughly equivalent to the following recursive function::
-
-        def foldl(func, start, seq):
-            if len(seq) == 0:
-                return start
-
-            return foldl(func, func(start, seq[0]), seq[1:])
-
-Speaking of equivalence, the above ``foldl`` call can be expressed in terms of the built-in ``reduce`` like
-so::
-
-        reduce(f, [1, 2, 3], 0)
-
-
-We can use ``foldl()``, ``operator.concat()`` and ``partial()`` to
-write a cleaner, more aesthetically-pleasing version of Python's
-``"".join(...)`` idiom::
-
-        from functional import foldl, partial
-        from operator import concat
-        
-        join = partial(foldl, concat, "")

-.. comment
-
-    Original outline:
-    Introduction
-            Idea of FP
-                    Programs built out of functions
-                    Functions are strictly input-output, no internal state
-            Opposed to OO programming, where objects have state
-
-            Why FP?
-                    Formal provability
-                            Assignment is difficult to reason about
-                            Not very relevant to Python
-                    Modularity
-                            Small functions that do one thing
-                    Debuggability:
-                            Easy to test due to lack of state
-                            Easy to verify output from intermediate steps
-                    Composability
-                            You assemble a toolbox of functions that can be mixed
-
-    Tackling a problem
-            Need a significant example
-
-    Iterators
-    Generators
-    The itertools module
-    List comprehensions
-    Small functions and the lambda statement
-    Built-in functions
-            map
-            filter
-            reduce
-
-.. comment
-
-    Handy little function for printing part of an iterator -- used
-    while writing this document.
-
-    import itertools
-    def print_iter(it):
-         slice = itertools.islice(it, 10)
-         for elem in slice[:-1]:
-             sys.stdout.write(str(elem))
-             sys.stdout.write(', ')
-        print elem[-1]

-// Koka language test module
-
-// This module implements the GarsiaWachs algorithm.
-// It is an adaptation of the algorithm in ML as described by JeanChristophe Filli�tre:
-// in ''A functional implementation of the GarsiaWachs algorithm. (functional pearl). ML workshop 2008, pages 91--96''.
-// See: http://www.lri.fr/~filliatr/publis/gwWml08.pdf
-//
-// The algorithm is interesting since it uses mutable references shared between a list and tree but the
-// side effects are not observable from outside. Koka automatically infers that the final algorithm is pure.
-// Note: due to a current limitation in the divergence analysis, koka cannot yet infer that mutually recursive
-// definitions in "insert" and "extract" are terminating and the final algorithm still has a divergence effect.
-// However, koka does infer that no other effect (i.e. an exception due to a partial match) can occur.

-
-  Returns a map containing :name and :bytecode. Most uses will be

-
-  :implements [interface ...]
-
-  One or more interfaces, the methods of which will be implemented by the class.
-
-  :init name
-
-  If supplied, names a function that will be called with the arguments
-  to the constructor. Must return [[superclass-constructor-args] state] 
-  If not supplied, the constructor args are passed directly to
-  the superclass constructor and the state will be nil
-
-  :constructors {[param-types] [super-param-types], ...}
-
-  By default, constructors are created for the generated class which
-  match the signature(s) of the constructors for the superclass. This
-  parameter may be used to explicitly specify constructors, each entry
-  providing a mapping from a constructor signature to a superclass
-  constructor signature. When you supply this, you must supply an :init
-  specifier.
-
-  :methods [[name [param-types] return-type], ...]
-
-  The generated class automatically defines all of the non-private
-  methods of its superclasses/interfaces. This parameter can be used
-  to specify the signatures of additional methods of the generated
-  class. Do not repeat superclass/interface signatures here.
-
-  :main boolean
-
-  If supplied and true, a static public main function will be
-  generated. It will pass each string of the String[] argument as a
-  separate argument to a function called 'main.
-
-  :factory name
-
-  If supplied, a (set of) public static factory function(s) will be
-  created with the given name, and the same signature(s) as the
-  constructor(s).
-  
-  :state name
-
-  If supplied, a public final instance field with the given name will be
-  created. You must supply an :init function in order to provide a
-  value for the state. Note that, though final, the state can be a ref
-  or agent, supporting the creation of Java objects with transactional
-  or asynchronous mutation semantics.
-
-  :exposes {protected-field-name {:get name :set name}, ...}
-
-  Since the implementations of the methods of the generated class
-  occur in Clojure functions, they have no access to the inherited
-  protected fields of the superclass. This parameter can be used to
-  generate public getter/setter methods exposing the protected field(s)
-  for use in the implementation."

-======================
-Designer Documentation
-======================
-
-This part of the Jinja documentaton is meant for template designers.
-
-Basics
-======
-
-The Jinja template language is designed to strike a balance between content
-and application logic. Nevertheless you can use a python like statement
-language. You don't have to know how Python works to create Jinja templates,
-but if you know it you can use some additional statements you may know from
-Python.
-
-Here is a small example template:
-
-.. sourcecode:: html+jinja
-
-    
-    
-    
-        My Webpage
-    
-    
-        
-
-        
    My Webpage
    
-        {{ variable }}
-    
-    
-
-This covers the default settings. The application developer might have changed
-the syntax from ``{% foo %}`` to ``<% foo %>`` or something similar. This
-documentation just covers the default values.
-
-A variable looks like ``{{ foobar }}`` where foobar is the variable name. Inside
-of statements (``{% some content here %}``) variables are just normal names
-without the braces around it. In fact ``{{ foobar }}`` is just an alias for
-the statement ``{% print foobar %}``.
-
-Variables are coming from the context provided by the application. Normally there
-should be a documentation regarding the context contents but if you want to know
-the content of the current context, you can add this to your template:
-
-.. sourcecode:: html+jinja
-
-    
    {{ debug()|e }}
    
-
-A context isn't flat which means that each variable can has subvariables, as long
-as it is representable as python data structure. You can access attributes of
-a variable using the dot and bracket operators. The following examples show
-this:
-
-.. sourcecode:: jinja
-
-    {{ user.username }}
-        is the same as
-    {{ user['username'] }}
-        you can also use a variable to access an attribute:
-    {{ users[current_user].username }}
-        If you have numerical indices you have to use the [] syntax:
-    {{ users[0].username }}
-
-Filters
-=======
-
-In the examples above you might have noticed the pipe symbols. Pipe symbols tell
-the engine that it has to apply a filter on the variable. Here is a small example:
-
-.. sourcecode:: jinja
-
-    {{ variable|replace('foo', 'bar')|escape }}
-
-If you want, you can also put whitespace between the filters.
-
-This will look for a variable `variable`, pass it to the filter `replace`
-with the arguments ``'foo'`` and ``'bar'``, and pass the result to the filter
-`escape` that automatically XML-escapes the value. The `e` filter is an alias for
-`escape`. Here is the complete list of supported filters:
-
-[[list_of_filters]]
-
-.. admonition:: note
-
-    Filters have a pretty low priority. If you want to add fitered values
-    you have to put them into parentheses. The same applies if you want to access
-    attributes:
-
-    .. sourcecode:: jinja
-
-        correct:
-            {{ (foo|filter) + (bar|filter) }}
-        wrong:
-            {{ foo|filter + bar|filter }}
-
-        correct:
-            {{ (foo|filter).attribute }}
-        wrong:
-            {{ foo|filter.attribute }}
-

-You can use the `is` operator to perform tests on a value:
-
-.. sourcecode:: jinja
-
-    {{ 42 is numeric }} -> true
-    {{ "foobar" is numeric }} -> false
-    {{ 'FOO' is upper }} -> true
-
-These tests are especially useful when used in `if` conditions.

-Global Functions
-================
-
-Test functions and filter functions live in their own namespace. Global
-functions not. They behave like normal objects in the context. Beside the
-functions added by the application or framewhere there are two functions
-available per default:
-
-`range`
-    
-    Works like the python `range function`_ just that it doesn't support
-    ranges greater than ``1000000``.
-
-`debug`
-
-    Function that outputs the contents of the context.
-
-Loops
-=====
-
-To iterate over a sequence, you can use the `for` loop. It basically looks like a
-normal Python `for` loop and works pretty much the same:
-
-.. sourcecode:: html+jinja
-
-    
    Members
    
-    
      
-    {% for user in users %}
-      
    • {{ loop.index }} / {{ loop.length }} - {{ user.username|escape }}
      • 
-    {% else %}
-      
    • no users found
      • 
-    {% endfor %}
-    
    
-
-*Important* Contrary to Python is the optional ``else`` block only
-executed if there was no iteration because the sequence was empty.
-
-Inside of a `for` loop block you can access some special variables:
-
-+----------------------+----------------------------------------+
-| Variable             | Description                            |
-+======================+========================================+
-| `loop.index`         | The current iteration of the loop.     |
-+----------------------+----------------------------------------+
-| `loop.index0`        | The current iteration of the loop,     |
-|                      | starting counting by 0.                |
-+----------------------+----------------------------------------+
-| `loop.revindex`      | The number of iterations from the end  |
-|                      | of the loop.                           |
-+----------------------+----------------------------------------+
-| `loop.revindex0`     | The number of iterations from the end  |
-|                      | of the loop, starting counting by 0.   |
-+----------------------+----------------------------------------+
-| `loop.first`         | True if first iteration.               |
-+----------------------+----------------------------------------+
-| `loop.last`          | True if last iteration.                |
-+----------------------+----------------------------------------+
-| `loop.even`          | True if current iteration is even.     |
-+----------------------+----------------------------------------+
-| `loop.odd`           | True if current iteration is odd.      |
-+----------------------+----------------------------------------+
-| `loop.length`        | Total number of items in the sequence. |
-+----------------------+----------------------------------------+
-| `loop.parent`        | The context of the parent loop.        |
-+----------------------+----------------------------------------+
-
-Loops also support recursion. Let's assume you have a sitemap where each item
-might have a number of child items. A template for that could look like this:
-
-.. sourcecode:: html+jinja
-
-    
    Sitemap
-    
      
-    {% for item in sitemap recursive %}
-      
    • {{ item.title|e }}
-      {% if item.children %}
        {{ loop(item.children) }}
      {% endif %}
      • 
-    {% endfor %}
-    
    
-
-What happens here? Basically the first thing that is different to a normal
-loop is the additional ``recursive`` modifier in the `for`-loop declaration.
-It tells the template engine that we want recursion. If recursion is enabled
-the special `loop` variable is callable. If you call it with a sequence it will
-automatically render the loop at that position with the new sequence as argument.
-
-Cycling
-=======
-
-Sometimes you might want to have different text snippets for each row in a list,
-for example to have alternating row colors. You can easily do this by using the
-``{% cycle %}`` tag:
-
-.. sourcecode:: html+jinja
-
-    
      
-    {% for message in messages %}
-      
    • {{ message|e }}
      • 
-    {% endfor %}
-    
    
-
-Each time Jinja encounters a `cycle` tag it will cycle through the list
-of given items and return the next one. If you pass it one item jinja assumes
-that this item is a sequence from the context and uses this:
-
-.. sourcecode:: html+jinja
-
-    
  • ...
    • 
-
-Conditions
-==========
-
-Jinja supports Python-like `if` / `elif` / `else` constructs:
-
-.. sourcecode:: jinja
-
-    {% if user.active %}
-        user {{ user.name|e }} is active.
-    {% elif user.deleted %}
-        user {{ user.name|e }} was deleted some time ago.
-    {% else %}
-        i don't know what's wrong with {{ user.username|e }}
-    {% endif %}
-
-If the user is active the first block is rendered. If not and the user was
-deleted the second one, in all other cases the third one.
-
-You can also use comparison operators:
-
-.. sourcecode:: html+jinja
-
-    {% if amount < 0 %}
-        {{ amount }}
-    {% else %}
-        {{ amount }}
-    {% endif %}
-
-.. admonition:: Note
-
-    Of course you can use `or` / `and` and parentheses to create more complex
-    conditions, but usually the logic is already handled in the application and
-    you don't have to create such complex constructs in the template code. However
-    in some situations it might be a good thing to have the abilities to create
-    them.
-
-Operators
-=========
-
-Inside ``{{ variable }}`` blocks, `if` conditions and many other parts you can
-can use expressions. In expressions you can use any of the following operators:
-
-    ======= ===================================================================
-    ``+``   add the right operand to the left one.
-            ``{{ 1 + 2 }}`` would return ``3``.
-    ``-``   subtract the right operand from the left one.
-            ``{{ 1 - 1 }}`` would return ``0``.
-    ``/``   divide the left operand by the right one.
-            ``{{ 1 / 2 }}`` would return ``0.5``.
-    ``*``   multiply the left operand with the right one.
-            ``{{ 2 * 2 }}`` would return ``4``.
-    ``**``  raise the left operand to the power of the right
-            operand. ``{{ 2**3 }}`` would return ``8``.
-    ``in``  perform sequence membership test. ``{{ 1 in [1,2,3] }}`` would
-            return true.
-    ``is``  perform a test on the value. See the section about
-            tests for more information.
-    ``|``   apply a filter on the value. See the section about
-            filters for more information.
-    ``and`` return true if the left and the right operand is true.
-    ``or``  return true if the left or the right operand is true.
-    ``not`` negate a statement (see below)
-    ``()``  call a callable: ``{{ user.get_username() }}``. Inside of the
-            parentheses you can use variables: ``{{ user.get(username) }}``.
-    ======= ===================================================================
-
-Note that there is no support for any bit operations or something similar.
-
-* special note regarding `not`: The `is` and `in` operators support negation
-  using an infix notation too: ``foo is not bar`` and ``foo not in bar``
-  instead of ``not foo is bar`` and ``not foo in bar``. All other expressions
-  require a prefix notation: ``not (foo and bar)``.
-
-Boolean Values
-==============
-
-In If-Conditions Jinja performs a boolean check. All empty values (eg: empty
-lists ``[]``, empty dicts ``{}`` etc) evaluate to `false`. Numbers that are
-equal to `0`/`0.00` are considered `false` too. The boolean value of other
-objects depends on the behavior the application developer gave it. Usually
-items are `true`.
-
-Here some examples that should explain it:
-
-.. sourcecode:: jinja
-
-    {% if [] %}
-        will always be false because it's an empty list
-
-    {% if {} %}
-        false too.
-
-    {% if ['foo'] %}
-        this is true. Because the list is not empty.
-
-    {% if "foobar" %}
-        this is also true because the string is not empty.
-
-Slicing
-=======
-
-Some objects support slicing operations. For example lists:
-
-.. sourcecode:: jinja
-
-    {% for item in items[:5] %}
-        This will only iterate over the first 5 items of the list
-
-    {% for item in items[5:10] %}
-        This will only iterate from item 5 to 10.
-
-    {% for item in items[:10:2] %}
-        This will only yield items from start to ten and only returing
-        even items.
-
-For more informations about slicing have a look at the `slicing chapter`_
-in the "Dive into Python" e-book.
-
-Macros
-======
-
-If you want to use a partial template in more than one place, you might want to
-create a macro from it:
-
-.. sourcecode:: html+jinja
-
-    {% macro show_user user %}
-      
    {{ user.name|e }}
    
-      
    
-        {{ user.description }}
-      
    
-    {% endmacro %}
-
-Now you can use it from everywhere in the code by passing it an item:
-
-.. sourcecode:: jinja
-    
-    {% for user in users %}
-        {{ show_user(user) }}
-    {% endfor %}
-
-You can also specify more than one value:
-
-.. sourcecode:: html+jinja
-
-    {% macro show_dialog title, text %}
-      
    
-        
    {{ title|e }}
    
-        
    {{ text|e }}
    
-      
    
-    {% endmacro %}
-
-    {{ show_dialog('Warning', 'something went wrong i guess') }}
-
-Inheritance
-===========
-
-The most powerful part of Jinja is template inheritance. Template inheritance
-allows you to build a base "skeleton" template that contains all the common
-elements of your site and defines **blocks** that child templates can override.
-
-Sounds complicated but is very basic. It's easiest to understand it by starting
-with an example.
-
-Base Template
--------------
-
-This template, which we'll call ``base.html``, defines a simple HTML skeleton
-document that you might use for a simple two-column page. It's the job of
-"child" templates to fill the empty blocks with content:
-
-.. sourcecode:: html+jinja
-
-    
-    
-    
-      
-      {% block title %}{% endblock %} - My Webpage
-      {% block html_head %}{% endblock %}
-    
-    
-      
    
-        {% block content %}{% endblock %}
-      
    
-
-      
-    
-
-In this example, the ``{% block %}`` tags define four blocks that child templates
-can fill in. All the `block` tag does is to tell the template engine that a
-child template may override those portions of the template.
-
-Child Template
---------------
-
-A child template might look like this:
-
-.. sourcecode:: html+jinja
-
-    {% extends "base.html" %}
-    {% block title %}Index{% endblock %}
-
-    {% block html_head %}
-      
-    {% endblock %}
-    
-    {% block content %}
-        
    Index
    
-        
    
-          Welcome on my awsome homepage.
-        
    
-    {% endblock %}
-
-The ``{% extends %}`` tag is the key here. It tells the template engine that
-this template "extends" another template. When the template system evaluates
-this template, first it locates the parent.
-
-The filename of the template depends on the template loader. For example the
-``FileSystemLoader`` allows you to access other templates by giving the
-filename. You can access templates in subdirectories with an slash:
-
-.. sourcecode:: jinja
-
-    {% extends "layout/default.html" %}
-
-But this behavior can depend on the application using Jinja.
-
-Note that since the child template didn't define the ``footer`` block, the
-value from the parent template is used instead.
-
-.. admonition:: Note
-
-    You can't define multiple ``{% block %}`` tags with the same name in the
-    same template. This limitation exists because a block tag works in "both"
-    directions. That is, a block tag doesn't just provide a hole to fill - it
-    also defines the content that fills the hole in the *parent*. If there were
-    two similarly-named ``{% block %}`` tags in a template, that template's
-    parent wouldn't know which one of the blocks' content to use.
-
-Template Inclusion
-==================
-
-You can load another template at a given position using ``{% include %}``.
-Usually it's a better idea to use inheritance but if you for example want to
-load macros, `include` works better than `extends`:
-
-.. sourcecode:: jinja
-
-    {% include "myhelpers.html" %}
-    {{ my_helper("foo") }}
-
-If you define a macro called ``my_helper`` in ``myhelpers.html``, you can now
-use it from the template as shown above.
-
-Filtering Blocks
-================
-
-Sometimes it could be a good idea to filter a complete block of text. For
-example, if you want to escape some html code:
-
-.. sourcecode:: jinja
-
-    {% filter escape %}
-        
-          goes here
-        
-    {% endfilter %}
-
-Of course you can chain filters too:
-
-.. sourcecode:: jinja
-
-    {% filter lower|escape %}
-        SOME TEXT
-    {% endfilter %}
-
-returns ``"<b>some text</b>"``.
-
-Defining Variables
-==================
-
-You can also define variables in the namespace using the ``{% set %}`` tag:
-
-.. sourcecode:: jinja
-
-    {% set foo = 'foobar' %}
-    {{ foo }}
-
-This should ouput ``foobar``.
-
-Scopes
-======
-
-Jinja has multiple scopes. A scope is something like a new transparent foil on
-a stack of foils. You can only write to the outermost foil but read all of them
-since you can look through them. If you remove the top foil all data on that
-foil disappears. Some tags in Jinja add a new layer to the stack. Currently
-these are `block`, `for`, `macro` and `filter`. This means that variables and
-other elements defined inside a macro, loop or some of the other tags listed
-above will be only available in that block. Here an example:
-
-.. sourcecode:: jinja
-
-    {% macro angryhello name %}
-      {% set angryname = name|upper %}
-      Hello {{ name }}. Hello {{ name }}!
-      HELLO {{ angryname }}!!!!!!111
-    {% endmacro %}
-
-The variable ``angryname`` just exists inside the macro, not outside it.
-
-Defined macros appear on the context as variables. Because of this, they are
-affected by the scoping too. A macro defined inside of a macro is just available
-in those two macros (the macro itself and the macro it's defined in). For `set`
-and `macro` two additional rules exist: If a macro is defined in an extended
-template but outside of a visible block (thus outside of any block) will be
-available in all blocks below. This allows you to use `include` statements to
-load often used macros at once.
-
-Undefined Variables
-===================
-
-If you have already worked with python you probably know about the fact that
-undefined variables raise an exception. This is different in Jinja. There is a
-special value called `undefined` that represents values that do not exist.
-
-This special variable works complete different from any variables you maybe
-know. If you print it using ``{{ variable }}`` it will not appear because it's
-literally empty. If you try to iterate over it, it will work. But no items
-are returned. Comparing this value to any other value results in `false`.
-Even if you compare it to itself:
-
-.. sourcecode:: jinja
-
-    {{ undefined == undefined }}
-        will return false. Not even undefined is undefined :)
-        Use `is defined` / `is not defined`:
-
-    {{ undefined is not defined }}
-        will return true.
-
-There are also some additional rules regarding this special value. Any
-mathematical operators (``+``, ``-``, ``*``, ``/``) return the operand
-as result:
-
-.. sourcecode:: jinja
-
-    {{ undefined + "foo" }}
-        returns "foo"
-
-    {{ undefined - 42 }}
-        returns 42. Note: not -42!
-
-In any expression `undefined` evaluates to `false`. It has no length, all
-attribute calls return undefined, calling too:
-
-.. sourcecode:: jinja
-
-    {{ undefined.attribute().attribute_too[42] }}
-        still returns `undefined`.
-
-Escaping
-========
-
-Sometimes you might want to add Jinja syntax elements into the template
-without executing them. In that case you have quite a few possibilities.
-
-For small parts this might be a good way:
-
-.. sourcecode:: jinja
-
-    {{ "{{ foo }} is variable syntax and {% foo %} is block syntax" }}
-
-When you have multiple elements you can use the ``raw`` block:
-
-.. sourcecode:: jinja
-
-    {% raw %}
-        Filtering blocks works like this in Jinja:
-        {% filter escape %}
-            
-              goes here
-            
-        {% endfilter %}
-    {% endraw %}
-
-Reserved Keywords
-=================
-
-Jinja has some keywords you cannot use a variable names. This limitation
-exists to make look coherent. Syntax highlighters won't mess things up and
-you will don't have unexpected output.
-
-The following keywords exist and cannot be used as identifiers:
-
-    `and`, `block`, `cycle`, `elif`, `else`, `endblock`, `endfilter`,
-    `endfor`, `endif`, `endmacro`, `endraw`, `endtrans`, `extends`, `filter`,
-    `for`, `if`, `in`, `include`, `is`, `macro`, `not`, `or`, `pluralize`,
-    `raw`, `recursive`, `set`, `trans`
-
-If you want to use such a name you have to prefix or suffix it or use
-alternative names:
-
-.. sourcecode:: jinja
-
-    {% for macro_ in macros %}
-        {{ macro_('foo') }}
-    {% endfor %}
-
-If future Jinja releases add new keywords those will be "light" keywords which
-means that they won't raise an error for several releases but yield warnings
-on the application side. But it's very unlikely that new keywords will be
-added.
-
-Internationalization
-====================
-
-If the application is configured for i18n, you can define translatable blocks
-for translators using the `trans` tag or the special underscore function:
-
-.. sourcecode:: jinja
-
-    {% trans %}
-        this is a translatable block
-    {% endtrans %}
-
-    {% trans "This is a translatable string" %}
-
-    {{ _("This is a translatable string") }}
-
-The latter one is useful if you want translatable arguments for filters etc.
-
-If you want to have plural forms too, use the `pluralize` block:
-
-.. sourcecode:: jinja
-
-    {% trans users=users %}
-        One user found.
-    {% pluralize %}
-        {{ users }} users found.
-    {% endtrans %}
-
-    {% trans first=(users|first).username|escape, user=users|length %}
-        one user {{ first }} found.
-    {% pluralize users %}
-        {{ users }} users found, the first one is called {{ first }}.
-    {% endtrans %}
-
-If you have multiple arguments, the first one is assumed to be the indicator (the
-number that is used to determine the correct singular or plural form. If you
-don't have the indicator variable on position 1 you have to tell the `pluralize`
-tag the correct variable name.
-
-Inside translatable blocks you cannot use blocks or expressions (however you can
-still use the ``raw`` block which will work as expected). The variable
-print syntax (``{{ variablename }}``) is the only way to insert the variables
-defined in the ``trans`` header. Filters must be applied in the header.
-
-.. admonition:: note
-
-    Please make sure that you always use pluralize blocks where required.
-    Many languages have more complex plural forms than the English language.
-    
-    Never try to workaround that issue by using something like this:
-
-    .. sourcecode:: jinja
-
-        {% if count != 1 %}
-            {{ count }} users found.
-        {% else %}
-            one user found.
-        {% endif %}

-(* Notes:
-   (1) Without dialect option nor embedded dialect tag, the lexer operates in
-       fallback mode, recognising the *combined* literals, punctuation symbols
-       and operators of all supported dialects, and the *combined* reserved
-       words and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10.
-   (1) If multiple embedded dialect tags are present, the lexer will use the
-       first valid tag and ignore any subsequent dialect tags in the file.
-   (2) An embedded dialect tag overrides any command line dialect option. *)

-

-

-
-        # Try to keep the user code from messing  with us. Save these so that
-        # even if the eval'ed code changes them, we can put them back again.
-        # Needed because the user could refer directly to the debugger's

-############################################## End lexical danger zone
-
-# After this point it is safe to introduce lexicals.
-# The code being debugged will be executing in its own context, and
-# can't see the inside of the debugger.
-#
-# However, one should not overdo it: leave as much control from outside as
-# possible. If you make something a lexical, it's not going to be addressable
-# from outside the debugger even if you know its name.
-
-# This file is automatically included if you do perl -d.
-# It's probably not useful to include this yourself.
-#
-# Before venturing further into these twisty passages, it is
-# wise to read the perldebguts man page or risk the ire of dragons.
-#
-# (It should be noted that perldebguts will tell you a lot about
-# the underlying mechanics of how the debugger interfaces into the
-# Perl interpreter, but not a lot about the debugger itself. The new
-# comments in this code try to address this problem.)
-
-# Note that no subroutine call is possible until &DB::sub is defined
-# (for subroutines defined outside of the package DB). In fact the same is
-# true if $deep is not defined.
-
-# Enhanced by ilya@math.ohio-state.edu (Ilya Zakharevich)
-
-# modified Perl debugger, to be run from Emacs in perldb-mode
-# Ray Lischner (uunet!mntgfx!lisch) as of 5 Nov 1990
-# Johan Vromans -- upgrade to 4.0 pl 10
-# Ilya Zakharevich -- patches after 5.001 (and some before ;-)
-
-# (We have made efforts to  clarify the comments in the change log
-# in other places; some of them may seem somewhat obscure as they
-# were originally written, and explaining them away from the code
-# in question seems conterproductive.. -JM)
-
-=head1 DEBUGGER INITIALIZATION
-
-The debugger starts up in phases.
-
-=head2 BASIC SETUP
-
-First, it initializes the environment it wants to run in: turning off
-warnings during its own compilation, defining variables which it will need
-to avoid warnings later, setting itself up to not exit when the program
-terminates, and defaulting to printing return values for the C command.
-
-=cut
-
-# Needed for the statement after exec():
-#
-# This BEGIN block is simply used to switch off warnings during debugger
-# compiliation. Probably it would be better practice to fix the warnings,
-# but this is how it's done at the moment.
-
-BEGIN {
-    $ini_warn = $^W;
-    $^W       = 0;
-}    # Switch compilation warnings off until another BEGIN.
-
-# test if assertions are supported and actived:
-BEGIN {
-    $ini_assertion = eval "sub asserting_test : assertion {1}; 1";
-
-    # $ini_assertion = undef => assertions unsupported,
-    #        "       = 1     => assertions supported
-    # print "\$ini_assertion=$ini_assertion\n";
-}
-
-local ($^W) = 0;    # Switch run-time warnings off during init.
-
-=head2 THREADS SUPPORT
-
-If we are running under a threaded Perl, we require threads and threads::shared
-if the environment variable C is set, to enable proper
-threaded debugger control.  C<-dt> can also be used to set this.
-
-Each new thread will be announced and the debugger prompt will always inform
-you of each new thread created.  It will also indicate the thread id in which
-we are currently running within the prompt like this:
-
-	[tid] DB<$i>
-
-Where C<[tid]> is an integer thread id and C<$i> is the familiar debugger
-command prompt.  The prompt will show: C<[0]> when running under threads, but
-not actually in a thread.  C<[tid]> is consistent with C usage.
-
-While running under threads, when you set or delete a breakpoint (etc.), this
-will apply to all threads, not just the currently running one.  When you are 
-in a currently executing thread, you will stay there until it completes.  With
-the current implementation it is not currently possible to hop from one thread
-to another.
-
-The C and C commands are currently fairly minimal - see C and C.
-
-Note that threading support was built into the debugger as of Perl version
-C<5.8.6> and debugger version C<1.2.8>.
-
-=cut
-
-BEGIN {
-  # ensure we can share our non-threaded variables or no-op
-  if ($ENV{PERL5DB_THREADED}) {
-	require threads;
-	require threads::shared;
-	import threads::shared qw(share);

-	lock($DBGR);
-	print "Threads support enabled\n";
-  } else {
-	*lock  = sub(*) {};
-	*share = sub(*) {};
-  }
-}
-
-# This would probably be better done with "use vars", but that wasn't around
-# when this code was originally written. (Neither was "use strict".) And on
-# the principle of not fiddling with something that was working, this was
-# left alone.

-# off warnings, because other packages may still want them.

-# value when the 'r' command is used to return from a subroutine.
-$inhibit_exit = $option{PrintRet} = 1;
-
-=head1 OPTION PROCESSING
-
-The debugger's options are actually spread out over the debugger itself and 
-C; some of these are variables to be set, while others are 
-subs to be called with a value. To try to make this a little easier to
-manage, the debugger uses a few data structures to define what options
-are legal and how they are to be processed.
-
-First, the C<@options> array defines the I of all the options that
-are to be accepted.
-
-=cut
-
-@options = qw(
-  CommandSet
-  hashDepth    arrayDepth    dumpDepth

-  inhibit_exit ImmediateStop bareStringify
-  CreateTTY    RemotePort    windowSize
-  DollarCaretP OnlyAssertions WarnAssertions
-);
-
-@RememberOnROptions = qw(DollarCaretP OnlyAssertions);
-

-
-Second, C lists the variables that each option uses to save its
-state.
-

-=head2 SETTING UP THE DEBUGGER GREETING
-

-running, and whether the current debugger is the primary or a child.
-
-If we are the primary, we just hang onto our pid so we'll have it when
-or if we start a child debugger. If we are a child, we'll set things up
-so we'll have a unique greeting and so the parent will give us our own
-TTY later.
-
-We save the current contents of the C environment variable
-because we mess around with it. We'll also need to hang onto it because
-we'll need it if we restart.
-
-Child debuggers make a label out of the current PID structure recorded in
-PERLDB_PIDS plus the new PID. They also mark themselves as not having a TTY
-yet so the parent will give them one later via C.

-=head2 READING THE RC FILE

-.IX Title "PERLFUNC 1"
-.TH PERLFUNC 1 "2006-01-07" "perl v5.8.8" "Perl Programmers Reference Guide"
-.SH "NAME"
-.IX Xref "function"
-perlfunc \- Perl builtin functions
-.SH "DESCRIPTION"
-.IX Header "DESCRIPTION"
-The functions in this section can serve as terms in an expression.
-They fall into two major categories: list operators and named unary
-operators.  These differ in their precedence relationship with a
-following comma.  (See the precedence table in perlop.)  List
-operators take more than one argument, while unary operators can never
-take more than one argument.  Thus, a comma terminates the argument of
-a unary operator, but merely separates the arguments of a list
-operator.  A unary operator generally provides a scalar context to its
-argument, while a list operator may provide either scalar or list
-contexts for its arguments.  If it does both, the scalar arguments will
-be first, and the list argument will follow.  (Note that there can ever
-be only one such list argument.)  For instance, \fIsplice()\fR has three scalar
-arguments followed by a list, whereas \fIgethostbyname()\fR has four scalar
-arguments.
-.PP
-In the syntax descriptions that follow, list operators that expect a
-list (and provide list context for the elements of the list) are shown
-with \s-1LIST\s0 as an argument.  Such a list may consist of any combination
-of scalar arguments or list values; the list values will be included
-in the list as if each individual element were interpolated at that
-point in the list, forming a longer single-dimensional list value.
-Commas should separate elements of the \s-1LIST\s0.
-.PP
-Any function in the list below may be used either with or without
-parentheses around its arguments.  (The syntax descriptions omit the
-parentheses.)  If you use the parentheses, the simple (but occasionally
-surprising) rule is this: It \fIlooks\fR like a function, therefore it \fIis\fR a
-function, and precedence doesn't matter.  Otherwise it's a list
-operator or unary operator, and precedence does matter.  And whitespace
-between the function and left parenthesis doesn't count\*(--so you need to
-be careful sometimes:
-.PP
-.Vb 5
-\&    print 1+2+4;        # Prints 7.
-\&    print(1+2) + 4;     # Prints 3.
-\&    print (1+2)+4;      # Also prints 3!
-\&    print +(1+2)+4;     # Prints 7.
-\&    print ((1+2)+4);    # Prints 7.
-.Ve
-.PP
-If you run Perl with the \fB\-w\fR switch it can warn you about this.  For
-example, the third line above produces:
-.PP
-.Vb 2
-\&    print (...) interpreted as function at - line 1.
-\&    Useless use of integer addition in void context at - line 1.
-.Ve
-.PP
-A few functions take no arguments at all, and therefore work as neither
-unary nor list operators.  These include such functions as \f(CW\*(C`time\*(C'\fR
-and \f(CW\*(C`endpwent\*(C'\fR.  For example, \f(CW\*(C`time+86_400\*(C'\fR always means
-\&\f(CW\*(C`time() + 86_400\*(C'\fR.
-.PP
-For functions that can be used in either a scalar or list context,
-nonabortive failure is generally indicated in a scalar context by
-returning the undefined value, and in a list context by returning the
-null list.
-.PP
-Remember the following important rule: There is \fBno rule\fR that relates
-the behavior of an expression in list context to its behavior in scalar
-context, or vice versa.  It might do two totally different things.
-Each operator and function decides which sort of value it would be most
-appropriate to return in scalar context.  Some operators return the
-length of the list that would have been returned in list context.  Some
-operators return the first value in the list.  Some operators return the
-last value in the list.  Some operators return a count of successful
-operations.  In general, they do what you want, unless you want
-consistency.
-.IX Xref "context"
-.PP
-A named array in scalar context is quite different from what would at
-first glance appear to be a list in scalar context.  You can't get a list
-like \f(CW\*(C`(1,2,3)\*(C'\fR into being in scalar context, because the compiler knows
-the context at compile time.  It would generate the scalar comma operator
-there, not the list construction version of the comma.  That means it
-was never a list to start with.
-.PP
-In general, functions in Perl that serve as wrappers for system calls
-of the same name (like \fIchown\fR\|(2), \fIfork\fR\|(2), \fIclosedir\fR\|(2), etc.) all return
-true when they succeed and \f(CW\*(C`undef\*(C'\fR otherwise, as is usually mentioned
-in the descriptions below.  This is different from the C interfaces,
-which return \f(CW\*(C`\-1\*(C'\fR on failure.  Exceptions to this rule are \f(CW\*(C`wait\*(C'\fR,
-\&\f(CW\*(C`waitpid\*(C'\fR, and \f(CW\*(C`syscall\*(C'\fR.  System calls also set the special \f(CW$!\fR
-variable on failure.  Other functions do not, except accidentally.

-The interpretation of the file permission operators \f(CW\*(C`\-r\*(C'\fR, \f(CW\*(C`\-R\*(C'\fR,
-\&\f(CW\*(C`\-w\*(C'\fR, \f(CW\*(C`\-W\*(C'\fR, \f(CW\*(C`\-x\*(C'\fR, and \f(CW\*(C`\-X\*(C'\fR is by default based solely on the mode
-of the file and the uids and gids of the user.  There may be other
-reasons you can't actually read, write, or execute the file.  Such
-reasons may be for example network filesystem access controls, ACLs
-(access control lists), read-only filesystems, and unrecognized
-executable formats.
-.Sp
-Also note that, for the superuser on the local filesystems, the \f(CW\*(C`\-r\*(C'\fR,
-\&\f(CW\*(C`\-R\*(C'\fR, \f(CW\*(C`\-w\*(C'\fR, and \f(CW\*(C`\-W\*(C'\fR tests always return 1, and \f(CW\*(C`\-x\*(C'\fR and \f(CW\*(C`\-X\*(C'\fR return 1
-if any execute bit is set in the mode.  Scripts run by the superuser
-may thus need to do a \fIstat()\fR to determine the actual mode of the file,
-or temporarily set their effective uid to something else.
-.Sp
-If you are using ACLs, there is a pragma called \f(CW\*(C`filetest\*(C'\fR that may
-produce more accurate results than the bare \fIstat()\fR mode bits.
-When under the \f(CW\*(C`use filetest 'access'\*(C'\fR the above-mentioned filetests
-will test whether the permission can (not) be granted using the
-\&\fIaccess()\fR family of system calls.  Also note that the \f(CW\*(C`\-x\*(C'\fR and \f(CW\*(C`\-X\*(C'\fR may
-under this pragma return true even if there are no execute permission
-bits set (nor any extra execute permission ACLs).  This strangeness is
-due to the underlying system calls' definitions.  Read the
-documentation for the \f(CW\*(C`filetest\*(C'\fR pragma for more information.
-.Sp
-Note that \f(CW\*(C`\-s/a/b/\*(C'\fR does not do a negated substitution.  Saying
-\&\f(CW\*(C`\-exp($foo)\*(C'\fR still works as expected, however\*(--only single letters
-following a minus are interpreted as file tests.
-.Sp
-The \f(CW\*(C`\-T\*(C'\fR and \f(CW\*(C`\-B\*(C'\fR switches work as follows.  The first block or so of the
-file is examined for odd characters such as strange control codes or
-characters with the high bit set.  If too many strange characters (>30%)
-are found, it's a \f(CW\*(C`\-B\*(C'\fR file; otherwise it's a \f(CW\*(C`\-T\*(C'\fR file.  Also, any file
-containing null in the first block is considered a binary file.  If \f(CW\*(C`\-T\*(C'\fR
-or \f(CW\*(C`\-B\*(C'\fR is used on a filehandle, the current \s-1IO\s0 buffer is examined
-rather than the first block.  Both \f(CW\*(C`\-T\*(C'\fR and \f(CW\*(C`\-B\*(C'\fR return true on a null
-file, or a file at \s-1EOF\s0 when testing a filehandle.  Because you have to
-read a file to do the \f(CW\*(C`\-T\*(C'\fR test, on most occasions you want to use a \f(CW\*(C`\-f\*(C'\fR
-against the file first, as in \f(CW\*(C`next unless \-f $file && \-T $file\*(C'\fR.
-.Sp
-If any of the file tests (or either the \f(CW\*(C`stat\*(C'\fR or \f(CW\*(C`lstat\*(C'\fR operators) are given
-the special filehandle consisting of a solitary underline, then the stat
-structure of the previous file test (or stat operator) is used, saving
-a system call.  (This doesn't work with \f(CW\*(C`\-t\*(C'\fR, and you need to remember
-that \fIlstat()\fR and \f(CW\*(C`\-l\*(C'\fR will leave values in the stat structure for the
-symbolic link, not the real file.)  (Also, if the stat buffer was filled by
-an \f(CW\*(C`lstat\*(C'\fR call, \f(CW\*(C`\-T\*(C'\fR and \f(CW\*(C`\-B\*(C'\fR will reset it with the results of \f(CW\*(C`stat _\*(C'\fR).

-Arranges to have a \s-1SIGALRM\s0 delivered to this process after the

-unfortunately, the elapsed time may be up to one second less or more
-than you specified because of how seconds are counted, and process
-scheduling may delay the delivery of the signal even further.)
-.Sp
-Only one timer may be counting at once.  Each call disables the
-previous timer, and an argument of \f(CW0\fR may be supplied to cancel the
-previous timer without starting a new one.  The returned value is the
-amount of time remaining on the previous timer.
-.Sp
-For delays of finer granularity than one second, you may use Perl's
-four-argument version of \fIselect()\fR leaving the first three arguments
-undefined, or you might be able to use the \f(CW\*(C`syscall\*(C'\fR interface to
-access \fIsetitimer\fR\|(2) if your system supports it.  The Time::HiRes
-module (from \s-1CPAN\s0, and starting from Perl 5.8 part of the standard

-fail with \f(CW$!\fR set to \f(CW\*(C`EINTR\*(C'\fR because Perl sets up signal handlers to

-Arranges for \s-1FILEHANDLE\s0 to be read or written in \*(L"binary\*(R" or \*(L"text\*(R"

-.Sp
-On some systems (in general, \s-1DOS\s0 and Windows-based systems) \fIbinmode()\fR
-is necessary when you're not working with a text file.  For the sake
-of portability it is a good idea to always use it when appropriate,
-and to never use it when it isn't appropriate.  Also, people can
-set their I/O to be by default \s-1UTF\-8\s0 encoded Unicode, not bytes.
-.Sp
-In other words: regardless of platform, use \fIbinmode()\fR on binary data,
-like for example images.
-.Sp
-If \s-1LAYER\s0 is present it is a single string, but may contain multiple

-.Sp
-\&\fIThe \s-1LAYER\s0 parameter of the \fIbinmode()\fI function is described as \*(L"\s-1DISCIPLINE\s0\*(R"
-in \*(L"Programming Perl, 3rd Edition\*(R".  However, since the publishing of this
-book, by many known as \*(L"Camel \s-1III\s0\*(R", the consensus of the naming of this
-functionality has moved from \*(L"discipline\*(R" to \*(L"layer\*(R".  All documentation
-of this version of Perl therefore refers to \*(L"layers\*(R" rather than to
-\&\*(L"disciplines\*(R".  Now back to the regularly scheduled documentation...\fR
-.Sp
-To mark \s-1FILEHANDLE\s0 as \s-1UTF\-8\s0, use \f(CW\*(C`:utf8\*(C'\fR.
-.Sp
-In general, \fIbinmode()\fR should be called after \fIopen()\fR but before any I/O
-is done on the filehandle.  Calling \fIbinmode()\fR will normally flush any
-pending buffered output data (and perhaps pending input data) on the
-handle.  An exception to this is the \f(CW\*(C`:encoding\*(C'\fR layer that
-changes the default character encoding of the handle, see open.
-The \f(CW\*(C`:encoding\*(C'\fR layer sometimes needs to be called in
-mid\-stream, and it doesn't flush the stream.  The \f(CW\*(C`:encoding\*(C'\fR
-also implicitly pushes on top of itself the \f(CW\*(C`:utf8\*(C'\fR layer because
-internally Perl will operate on \s-1UTF\-8\s0 encoded Unicode characters.
-.Sp
-The operating system, device drivers, C libraries, and Perl run-time
-system all work together to let the programmer treat a single
-character (\f(CW\*(C`\en\*(C'\fR) as the line terminator, irrespective of the external
-representation.  On many operating systems, the native text file
-representation matches the internal representation, but on some
-platforms the external representation of \f(CW\*(C`\en\*(C'\fR is made up of more than
-one character.
-.Sp
-Mac \s-1OS\s0, all variants of Unix, and Stream_LF files on \s-1VMS\s0 use a single
-character to end each line in the external representation of text (even
-though that single character is \s-1CARRIAGE\s0 \s-1RETURN\s0 on Mac \s-1OS\s0 and \s-1LINE\s0 \s-1FEED\s0
-on Unix and most \s-1VMS\s0 files). In other systems like \s-1OS/2\s0, \s-1DOS\s0 and the
-various flavors of MS-Windows your program sees a \f(CW\*(C`\en\*(C'\fR as a simple \f(CW\*(C`\ecJ\*(C'\fR,
-but what's stored in text files are the two characters \f(CW\*(C`\ecM\ecJ\*(C'\fR.  That
-means that, if you don't use \fIbinmode()\fR on these systems, \f(CW\*(C`\ecM\ecJ\*(C'\fR
-sequences on disk will be converted to \f(CW\*(C`\en\*(C'\fR on input, and any \f(CW\*(C`\en\*(C'\fR in
-your program will be converted back to \f(CW\*(C`\ecM\ecJ\*(C'\fR on output.  This is what
-you want for text files, but it can be disastrous for binary files.
-.Sp
-Another consequence of using \fIbinmode()\fR (on some systems) is that
-special end-of-file markers will be seen as part of the data stream.
-For systems from the Microsoft family this means that if your binary
-data contains \f(CW\*(C`\ecZ\*(C'\fR, the I/O subsystem will regard it as the end of
-the file, unless you use \fIbinmode()\fR.
-.Sp
-\&\fIbinmode()\fR is not only important for \fIreadline()\fR and \fIprint()\fR operations,
-but also when using \fIread()\fR, \fIseek()\fR, \fIsysread()\fR, \fIsyswrite()\fR and \fItell()\fR

-Summary:	phpMyAdmin - web-based MySQL administration
-
-%description
-phpMyAdmin can manage a whole MySQL-server (needs a super-user) but
-also a single database. To accomplish the latter you'll need a
-properly set up MySQL-user which can read/write only the desired
-database. It's up to you to look up the appropiate part in the MySQL
-manual. Currently phpMyAdmin can:
-  - create and drop databases
-  - create, copy, drop and alter tables
-  - delete, edit and add fields
-  - execute any SQL-statement, even batch-queries
-  - manage keys on fields
-  - load text files into tables
-  - create (*) and read dumps of tables
-  - export (*) and import data to CSV values
-  - administer multiple servers and single databases
-  - check referencial integrity
-  - create complex queries automatically connecting required tables
-  - create PDF graphics of your database layout
-  - communicate in more than 38 different languages

-;;
-;; This is my first attempt at writing a simple application using newLISP-GS.

-(defmacro declare-function (_fn _file &optional _arglist _fileonly)
-  "Tell the byte-compiler that function FN is defined, in FILE.
-Optional ARGLIST is the argument list used by the function.
-The FILE argument is not used by the byte-compiler, but by the
-`check-declare' package, which checks that FILE contains a
-definition for FN.  ARGLIST is used by both the byte-compiler
-and `check-declare' to check for consistency.
-
-FILE can be either a Lisp file (in which case the \".el\"
-extension is optional), or a C file.  C files are expanded
-relative to the Emacs \"src/\" directory.  Lisp files are
-searched for using `locate-library', and if that fails they are
-expanded relative to the location of the file containing the
-declaration.  A FILE with an \"ext:\" prefix is an external file.
-`check-declare' will check such files if they are found, and skip
-them without error if they are not.
-
-FILEONLY non-nil means that `check-declare' will only check that
-FILE exists, not that it defines FN.  This is intended for
-function-definitions that `check-declare' does not recognize, e.g.
-`defstruct'.
-
-To specify a value for FILEONLY without passing an argument list,
-set ARGLIST to t.  This is necessary because nil means an
-empty argument list, rather than an unspecified one.
-
-Note that for the purposes of `check-declare', this statement
-must be the first non-whitespace on a line.

-For more information, see Info node `(elisp)Declaring Functions'."

-// std::vector
-// 
-// The aim of all that follows would be to integrate std::vector with 
-// as much as possible, namely, to allow the user to pass and 
-// be returned tuples or lists.
-// const declarations are used to guess the intent of the function being
-// exported; therefore, the following rationale is applied:
-// 
-//   -- f(std::vector), f(const std::vector&):
-//      the parameter being read-only, either a sequence or a
-//      previously wrapped std::vector can be passed.
-//   -- f(std::vector&), f(std::vector*):
-//      the parameter may be modified; therefore, only a wrapped std::vector
-//      can be passed.
-//   -- std::vector f(), const std::vector& f():
-//      the vector is returned by copy; therefore, a sequence of T:s 
-//      is returned which is most easily used in other functions
-//   -- std::vector& f(), std::vector* f():
-//      the vector is returned by reference; therefore, a wrapped std::vector
-//      is returned

-.SYNOPSIS
-Runs a T-SQL Query and optional outputs results to a delimited file.
-.DESCRIPTION
-Invoke-Sql script will run a T-SQL query or stored procedure and optionally outputs a delimited file.
-.EXAMPLE
-PowerShell.exe -File "C:\Scripts\Invoke-Sql.ps1" -ServerInstance "Z003\sqlprod2" -Database orders -Query "EXEC usp_accounts '12445678'"
-This example connects to Z003\sqlprod2.Orders and executes a stored procedure which does not return a result set
-.EXAMPLE
-PowerShell.exe -File "C:\Scripts\Invoke-Sql.ps1" -ServerInstance "Z003\sqlprod2" -Database orders -Query "SELECT * FROM dbo.accounts" -FilePath "C:\Scripts\accounts.txt" -Delimiter ","
-This example connects to Z003\sqlprod2.Orders and selects the records from the accounts tables, the data is outputed to a CSV file

-;;; Datenstrukturen für TYPEP:
-;;; - Ein Type-Specifier-Symbol hat auf seiner Propertyliste unter dem
-;;;   Indikator SYS::TYPE-SYMBOL eine Funktion von einem Argument, die
-;;;   testet, ob ein Objekt vom richtigen Typ ist.
-;;; - Ein Symbol, das eine Type-Specifier-Liste beginnen kann, hat auf seiner
-;;;   Propertyliste unter dem Indikator SYS::TYPE-LIST eine Funktion von
-;;;   einem Argument für das zu testende Objekt und zusätzlichen Argumenten
-;;;   für die Listenelemente.
-;;; - Ein Symbol, das als Typmacro definiert wurde, hat auf seiner Property-
-;;;   liste unter dem Indikator SYSTEM::DEFTYPE-EXPANDER den zugehörigen
-;;;   Expander: eine Funktion, die den zu expandierenden Type-Specifier (eine
-;;;   mindestens einelementige Liste) als Argument bekommt.

-subroutine psb_zmlprc_aply(alpha,baseprecv,x,beta,y,desc_data,trans,work,info)
-  !
-  !  Compute   Y <-  beta*Y + alpha*K^-1 X
-  !  where K is a multilevel  preconditioner stored in baseprecv
-  !
-  !  cfr.: Smith, Biorstad & Gropp
-  !        Domain Decomposition
-  !        Cambridge Univ. Press
-  !
-  !  To each level I there corresponds a matrix A(I) and a preconditioner K(I)
-  !
-  !  A notational difference: in the DD reference above the preconditioner for
-  !  a given level K(I) is written out as a sum over the subdomains
-  !
-  !  SUM_k(R_k^T A_k R_k)
-  !
-  !  whereas in this code the sum is implicit in the parallelization,
-  !  i.e. each process takes care of one subdomain, and for each level we have
-  !  as many subdomains as there are processes (except for the coarsest level where
-  !  we might have a replicated index space). Thus the sum apparently disappears
-  !  from our code, but only apparently, because it is implicit in the call
-  !  to psb_baseprc_aply.
-  !
-  !  A bit of description of the baseprecv(:) data structure:
-  !   1. Number of levels = NLEV = size(baseprecv(:))
-  !   2. baseprecv(ilev)%av(:)    sparse matrices needed for the current level.
-  !      Includes:
-  !   2.1.:  baseprecv(ilev)%av(l_pr_)    L factor of ILU preconditioners
-  !   2.2.:  baseprecv(ilev)%av(u_pr_)    U factor of ILU preconditioners
-  !   2.3.:  baseprecv(ilev)%av(ap_nd_)   Off-diagonal part of A for Jacobi sweeps
-  !   2.4.:  baseprecv(ilev)%av(ac_)      Aggregated matrix of level ILEV
-  !   2.5.:  baseprecv(ilev)%av(sm_pr_t_) Smoother prolongator transpose; maps vectors
-  !                                          (ilev-1) --->  (ilev)
-  !   2.6.:  baseprecv(ilev)%av(sm_pr_)   Smoother prolongator; maps vectors
-  !                                          (ilev)   --->  (ilev-1)
-  !   Shouldn't we keep just one of them and handle transpose in the sparse BLAS? maybe
-  !
-  !   3.    baseprecv(ilev)%desc_data     comm descriptor for level ILEV
-  !   4.    baseprecv(ilev)%base_a        Pointer (really a pointer!) to the base matrix
-  !                                       of the current level, i.e.: if ILEV=1 then  A
-  !                                       else the aggregated matrix av(ac_); so we have
-  !                                       a unified treatment of residuals. Need this to
-  !                                       avoid passing explicitly matrix A to the
-  !                                       outer prec. routine
-  !   5.    baseprecv(ilev)%mlia          The aggregation map from (ilev-1)-->(ilev)
-  !                                       if no smoother, it is used instead of sm_pr_
-  !   6.    baseprecv(ilev)%nlaggr        Number of aggregates on the various procs.

-Blackfriday
-[![Build Status][BuildV2SVG]][BuildV2URL]
-[![PkgGoDev][PkgGoDevV2SVG]][PkgGoDevV2URL]
-===========
-
-Blackfriday is a [Markdown][1] processor implemented in [Go][2]. It
-is paranoid about its input (so you can safely feed it user-supplied
-data), it is fast, it supports common extensions (tables, smart
-punctuation substitutions, etc.), and it is safe for all utf-8
-(unicode) input.
-
-HTML output is currently supported, along with Smartypants
-extensions.
-
-It started as a translation from C of [Sundown][3].
-
-
-Installation
-------------
-
-Blackfriday is compatible with modern Go releases in module mode.
-With Go installed:
-
-    go get github.com/russross/blackfriday/v2
-
-will resolve and add the package to the current development module,
-then build and install it. Alternatively, you can achieve the same
-if you import it in a package:
-
-    import "github.com/russross/blackfriday/v2"
-
-and `go get` without parameters.
-
-Legacy GOPATH mode is unsupported.
-
-
-Versions
---------
-
-Currently maintained and recommended version of Blackfriday is `v2`. It's being
-developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the
-documentation is available at
-https://pkg.go.dev/github.com/russross/blackfriday/v2.
-
-It is `go get`-able in module mode at `github.com/russross/blackfriday/v2`.
-
-Version 2 offers a number of improvements over v1:
-
-* Cleaned up API
-* A separate call to [`Parse`][4], which produces an abstract syntax tree for
-  the document
-* Latest bug fixes
-* Flexibility to easily add your own rendering extensions
-
-Potential drawbacks:
-
-* Our benchmarks show v2 to be slightly slower than v1. Currently in the
-  ballpark of around 15%.
-* API breakage. If you can't afford modifying your code to adhere to the new API
-  and don't care too much about the new features, v2 is probably not for you.
-* Several bug fixes are trailing behind and still need to be forward-ported to
-  v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for
-  tracking.
-
-If you are still interested in the legacy `v1`, you can import it from
-`github.com/russross/blackfriday`. Documentation for the legacy v1 can be found
-here: https://pkg.go.dev/github.com/russross/blackfriday.
-
-
-Usage
------
-
-For the most sensible markdown processing, it is as simple as getting your input
-into a byte slice and calling:
-
-```go
-output := blackfriday.Run(input)
-```
-
-Your input will be parsed and the output rendered with a set of most popular
-extensions enabled. If you want the most basic feature set, corresponding with
-the bare Markdown specification, use:
-
-```go
-output := blackfriday.Run(input, blackfriday.WithNoExtensions())
-```
-
-### Sanitize untrusted content
-
-Blackfriday itself does nothing to protect against malicious content. If you are
-dealing with user-supplied markdown, we recommend running Blackfriday's output
-through HTML sanitizer such as [Bluemonday][5].
-
-Here's an example of simple usage of Blackfriday together with Bluemonday:
-
-```go
-import (
-    "github.com/microcosm-cc/bluemonday"
-    "github.com/russross/blackfriday/v2"
-)
-
-// ...
-unsafe := blackfriday.Run(input)
-html := bluemonday.UGCPolicy().SanitizeBytes(unsafe)
-```
-
-### Custom options
-
-If you want to customize the set of options, use `blackfriday.WithExtensions`,
-`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`.
-
-### `blackfriday-tool`
-
-You can also check out `blackfriday-tool` for a more complete example
-of how to use it. Download and install it using:
-
-    go get github.com/russross/blackfriday-tool
-
-This is a simple command-line tool that allows you to process a
-markdown file using a standalone program.  You can also browse the
-source directly on github if you are just looking for some example
-code:
-
-* 
-
-Note that if you have not already done so, installing
-`blackfriday-tool` will be sufficient to download and install
-blackfriday in addition to the tool itself. The tool binary will be
-installed in `$GOPATH/bin`.  This is a statically-linked binary that
-can be copied to wherever you need it without worrying about
-dependencies and library versions.
-
-### Sanitized anchor names
-
-Blackfriday includes an algorithm for creating sanitized anchor names
-corresponding to a given input text. This algorithm is used to create
-anchors for headings when `AutoHeadingIDs` extension is enabled. The
-algorithm has a specification, so that other packages can create
-compatible anchor names and links to those anchors.
-
-The specification is located at https://pkg.go.dev/github.com/russross/blackfriday/v2#hdr-Sanitized_Anchor_Names.
-
-[`SanitizedAnchorName`](https://pkg.go.dev/github.com/russross/blackfriday/v2#SanitizedAnchorName) exposes this functionality, and can be used to
-create compatible links to the anchor names generated by blackfriday.
-This algorithm is also implemented in a small standalone package at
-[`github.com/shurcooL/sanitized_anchor_name`](https://pkg.go.dev/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients
-that want a small package and don't need full functionality of blackfriday.
-
-
-Features
---------
-
-All features of Sundown are supported, including:
-
-*   **Compatibility**. The Markdown v1.0.3 test suite passes with
-    the `--tidy` option.  Without `--tidy`, the differences are
-    mostly in whitespace and entity escaping, where blackfriday is
-    more consistent and cleaner.
-
-*   **Common extensions**, including table support, fenced code
-    blocks, autolinks, strikethroughs, non-strict emphasis, etc.
-
-*   **Safety**. Blackfriday is paranoid when parsing, making it safe
-    to feed untrusted user input without fear of bad things
-    happening. The test suite stress tests this and there are no
-    known inputs that make it crash.  If you find one, please let me
-    know and send me the input that does it.
-
-    NOTE: "safety" in this context means *runtime safety only*. In order to
-    protect yourself against JavaScript injection in untrusted content, see
-    [this example](https://github.com/russross/blackfriday#sanitize-untrusted-content).
-
-*   **Fast processing**. It is fast enough to render on-demand in
-    most web applications without having to cache the output.
-
-*   **Thread safety**. You can run multiple parsers in different
-    goroutines without ill effect. There is no dependence on global
-    shared state.
-
-*   **Minimal dependencies**. Blackfriday only depends on standard
-    library packages in Go. The source code is pretty
-    self-contained, so it is easy to add to any project, including
-    Google App Engine projects.
-
-*   **Standards compliant**. Output successfully validates using the
-    W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
-
-
-Extensions
-----------
-
-In addition to the standard markdown syntax, this package
-implements the following extensions:
-
-*   **Intra-word emphasis supression**. The `_` character is
-    commonly used inside words when discussing code, so having
-    markdown interpret it as an emphasis command is usually the
-    wrong thing. Blackfriday lets you treat all emphasis markers as
-    normal characters when they occur inside a word.
-
-*   **Tables**. Tables can be created by drawing them in the input
-    using a simple syntax:
-
-    ```
-    Name    | Age
-    --------|------
-    Bob     | 27
-    Alice   | 23
-    ```
-
-*   **Fenced code blocks**. In addition to the normal 4-space
-    indentation to mark code blocks, you can explicitly mark them
-    and supply a language (to make syntax highlighting simple). Just
-    mark it like this:
-
-        ```go
-        func getTrue() bool {
-            return true
-        }
-        ```
-
-    You can use 3 or more backticks to mark the beginning of the
-    block, and the same number to mark the end of the block.
-
-    To preserve classes of fenced code blocks while using the bluemonday
-    HTML sanitizer, use the following policy:
-
-    ```go
-    p := bluemonday.UGCPolicy()
-    p.AllowAttrs("class").Matching(regexp.MustCompile("^language-[a-zA-Z0-9]+$")).OnElements("code")
-    html := p.SanitizeBytes(unsafe)
-    ```
-
-*   **Definition lists**. A simple definition list is made of a single-line
-    term followed by a colon and the definition for that term.
-
-        Cat
-        : Fluffy animal everyone likes
-
-        Internet
-        : Vector of transmission for pictures of cats
-
-    Terms must be separated from the previous definition by a blank line.
-
-*   **Footnotes**. A marker in the text that will become a superscript number;
-    a footnote definition that will be placed in a list of footnotes at the
-    end of the document. A footnote looks like this:
-
-        This is a footnote.[^1]
-
-        [^1]: the footnote text.
-
-*   **Autolinking**. Blackfriday can find URLs that have not been
-    explicitly marked as links and turn them into links.
-
-*   **Strikethrough**. Use two tildes (`~~`) to mark text that
-    should be crossed out.
-
-*   **Hard line breaks**. With this extension enabled newlines in the input
-    translate into line breaks in the output. This extension is off by default.
-
-*   **Smart quotes**. Smartypants-style punctuation substitution is
-    supported, turning normal double- and single-quote marks into
-    curly quotes, etc.
-
-*   **LaTeX-style dash parsing** is an additional option, where `--`
-    is translated into `–`, and `---` is translated into
-    `—`. This differs from most smartypants processors, which
-    turn a single hyphen into an ndash and a double hyphen into an
-    mdash.
-
-*   **Smart fractions**, where anything that looks like a fraction
-    is translated into suitable HTML (instead of just a few special
-    cases like most smartypant processors). For example, `4/5`
-    becomes `4⁄5`, which renders as
-    4⁄5.
-
-
-Other renderers
----------------
-
-Blackfriday is structured to allow alternative rendering engines. Here
-are a few of note:
-
-*   [github_flavored_markdown](https://pkg.go.dev/github.com/shurcooL/github_flavored_markdown):
-    provides a GitHub Flavored Markdown renderer with fenced code block
-    highlighting, clickable heading anchor links.
-
-    It's not customizable, and its goal is to produce HTML output
-    equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode),
-    except the rendering is performed locally.
-
-*   [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
-    but for markdown.
-
-*   [LaTeX output](https://gitlab.com/ambrevar/blackfriday-latex):
-    renders output as LaTeX.
-
-*   [bfchroma](https://github.com/Depado/bfchroma/): provides convenience
-    integration with the [Chroma](https://github.com/alecthomas/chroma) code
-    highlighting library. bfchroma is only compatible with v2 of Blackfriday and
-    provides a drop-in renderer ready to use with Blackfriday, as well as
-    options and means for further customization.
-
-*   [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer.
-
-*   [Blackfriday-Slack](https://github.com/karriereat/blackfriday-slack): converts markdown to slack message style
-
-
-TODO
-----
-
-*   More unit testing
-*   Improve Unicode support. It does not understand all Unicode
-    rules (about what constitutes a letter, a punctuation symbol,
-    etc.), so it may fail to detect word boundaries correctly in
-    some instances. It is safe on all UTF-8 input.

-// Package blackfriday is a markdown processor.
-//
-// It translates plain text with simple formatting rules into an AST, which can
-// then be further processed to HTML (provided by Blackfriday itself) or other
-// formats (provided by the community).
-//
-// The simplest way to invoke Blackfriday is to call the Run function. It will
-// take a text input and produce a text output in HTML (or other format).
-//
-// A slightly more sophisticated way to use Blackfriday is to create a Markdown
-// processor and to call Parse, which returns a syntax tree for the input
-// document. You can leverage Blackfriday's parsing for content extraction from
-// markdown documents. You can assign a custom renderer and set various options
-// to the Markdown processor.
-//
-// If you're interested in calling Blackfriday from command line, see
-// https://github.com/russross/blackfriday-tool.
-//
-// Sanitized Anchor Names
-//
-// Blackfriday includes an algorithm for creating sanitized anchor names
-// corresponding to a given input text. This algorithm is used to create
-// anchors for headings when AutoHeadingIDs extension is enabled. The
-// algorithm is specified below, so that other packages can create
-// compatible anchor names and links to those anchors.
-//
-// The algorithm iterates over the input text, interpreted as UTF-8,
-// one Unicode code point (rune) at a time. All runes that are letters (category L)
-// or numbers (category N) are considered valid characters. They are mapped to
-// lower case, and included in the output. All other runes are considered
-// invalid characters. Invalid characters that precede the first valid character,
-// as well as invalid character that follow the last valid character
-// are dropped completely. All other sequences of invalid characters
-// between two valid characters are replaced with a single dash character '-'.
-//
-// SanitizedAnchorName exposes this functionality, and can be used to
-// create compatible links to the anchor names generated by blackfriday.
-// This algorithm is also implemented in a small standalone package at
-// github.com/shurcooL/sanitized_anchor_name. It can be useful for clients
-// that want a small package and don't need full functionality of blackfriday.
-package blackfriday
-
-// NOTE: Keep Sanitized Anchor Name algorithm in sync with package
-//       github.com/shurcooL/sanitized_anchor_name.
-//       Otherwise, users of sanitized_anchor_name will get anchor names
-//       that are incompatible with those generated by blackfriday.

-// Link references

-//    [1]: http://www.google.com/ "Google"
-//    [2]: http://www.github.com/ "Github"
-//
-// Anywhere in the document, the reference can be linked by referring to its
-// label, i.e., 1 and 2 in this example, as in:
-//
-//    This library is hosted on [Github][2], a git hosting site.
-//
-// Actual footnotes as specified in Pandoc and supported by some other Markdown
-// libraries such as php-markdown are also taken care of. They look like this:
-//
-//    This sentence needs a bit of further explanation.[^note]
-//
-//    [^note]: This is the explanation.
-//
-// Footnotes should be placed at the end of the document in an ordered list.
-// Finally, there are inline footnotes such as:
-//
-//    Inline footnotes^[Also supported.] provide a quick inline explanation,
-//    but are rendered at the bottom of the document.
-//
-
-// reference holds all information necessary for a reference-style links or
-// footnotes.
-//
-// Consider this markdown with reference-style links:
-//
-//     [link][ref]
-//
-//     [ref]: /url/ "tooltip title"

-// It will be ultimately converted to this HTML:

-//     p.refs["ref"] = &reference{
-//         link: "/url/",
-//         title: "tooltip title",
-//     }
-//
-// Alternatively, reference can contain information about a footnote. Consider
-// this markdown:
-//
-//     Text needing a footnote.[^a]
-//
-//     [^a]: This is the note
-//

Subject: [PATCH 081/283] Clarify comment for the goroutines sample (#366)

* Clarify comment for the goroutines sample.

The current comment may be interpreted to say that the output must be
interleaved, when in fact it doesn't have to be (it depends on the order
the goroutines are run). Make the comment more permissive to avoid the
confusion.

Fixes #365

* Fix phrasing in comment

Subject: [PATCH 101/283] Minor fixes (#396)

* Add missing word

* Rename `boolPtr` to `forkPtr`

This is in order to be consistent with the other flags `wordPtr` &
`numbPtr` which are based on the name of the flag and not the type of
the flag.

    A container embeds a base. An embedding looks

    We can access the base’s fields directly on co,

    Since container embeds base, the methods of
+base also become methods of a container. Here
+we invoke a method that was embedded from base
+directly on co.

    Unit testing is an important part of writing
+principled Go programs. The testing package
+provides the tools we need to write unit tests
+and the go test command runs tests.
    
+
+              		
+            
+          
+          
    
+            
    For the sake of demonstration, this code is in package
+main, but it could be any package. Testing code
+typically lives in the same package as the code it tests.
    
+
+              		
+            
+          
    +package main
+
    
+          
    
+            
+          
+            
+          
    import (
+    "fmt"
+    "testing"
+)
+
    
+          
    
+            
    We’ll be testing this simple implementation of an
+integer minimum. Typically, the code we’re testing
+would be in a source file named something like
+intutils.go, and the test file for it would then
+be named intutils_test.go.
    
+
+              		
+            
+          
    +func IntMin(a, b int) int {
+    if a < b {
+        return a
+    }
+    return b
+}
+
    
+          
    
+            
    A test is created by writing a function with a name
+beginning with Test.
    
+
+              		
+            
+          
    +func TestIntMinBasic(t *testing.T) {
+    ans := IntMin(2, -2)
+    if ans != -2 {
+
    
+          
    
+            
    t.Error* will report test failures but continue
+executing the test. t.Fatal* will report test
+failures and stop the test immediately.
    
+
+              		
+            
+          
    +        t.Errorf("IntMin(2, -2) = %d; want -2", ans)
+    }
+}
+
    
+          
    
+            
    Writing tests can be repetitive, so it’s idiomatic to
+use a table-driven style, where test inputs and
+expected outputs are listed in a table and a single loop
+walks over them and performs the test logic.
    
+
+              		
+            
+          
    +func TestIntMinTableDriven(t *testing.T) {
+    var tests = []struct {
+        a, b int
+        want int
+    }{
+        {0, 1, 0},
+        {1, 0, 0},
+        {2, -2, -2},
+        {0, -1, -1},
+        {-1, 0, -1},
+    }
+
    
+          
    
+            
    t.Run enables running “subtests”, one for each
+table entry. These are shown separately
+when executing go test -v.
    
+
+              		
+            
+          
        for _, tt := range tests {
+
    
+          
    
+            
+          
+            
+          
            testname := fmt.Sprintf("%d,%d", tt.a, tt.b)
+        t.Run(testname, func(t *testing.T) {
+            ans := IntMin(tt.a, tt.b)
+            if ans != tt.want {
+                t.Errorf("got %d, want %d", ans, tt.want)
+            }
+        })
+    }
+}
+
    
+          
    
+            
    Benchmark tests typically go in _test.go files and are
+named beginning with Benchmark. The testing runner
+executes each benchmark function several times, increasing
+b.N on each run until it collects a precise measurement.
    
+
+              		
+            
+          
    +func BenchmarkIntMin(b *testing.B) {
+
    
+          
    
+            
    Typically the benchmark runs a function we’re
+benchmarking in a loop b.N times.
    
+
+              		
+            
+          
    +    for i := 0; i < b.N; i++ {
+        IntMin(1, 2)
+    }

+### FAQ
+
+#### I'm getting output in a different order from the example. Is the example wrong?
+
+Some of the examples demonstrate concurrent code which has a non-deterministic
+execution order. It depends on how the Go runtime schedules its goroutines and
+may vary by operating system, CPU architecture, or even Go version.
+
+It doesn't mean anything is wrong with the example. Typically the code in these
+examples will be insensitive to the actual order of the output; if the code is
+sensitive to the order - that's probably a bug - so feel free to report it.

Subject: [PATCH 114/283] Update `Epoch` example to add UnixMilli from Time
 package (#409)

Standard library time package has support for UnixMilli - https://pkg.go.dev/time#Time.UnixMilli
Updated the example to use the method on Time instead of calculating.

 ### FAQ
 
+#### What version of Go is required to run these examples?
+
+Given Go's strong [backwards compatibility guarantees](https://go.dev/doc/go1compat),
+we expect the vast majority of examples to work on the latest released version of Go
+as well as many older releases going back years.
+
+That said, some examples show off new features added in the latest release; therefore,
+it's recommended to try running examples with the latest officially released Go version
+(see Go's [release history](https://go.dev/doc/devel/release) for details).
+
 #### I'm getting output in a different order from the example. Is the example wrong?
 
 Some of the examples demonstrate concurrent code which has a non-deterministic

    A Go string is a read-only slice of bytes. The language
+and the standard library treat strings specially - as
+containers of text encoded in UTF-8.
+In other languages, strings are made of “characters”.
+In Go, the concept of a character is called a rune - it’s
+an integer that represents a Unicode code point.
+This Go blog post is a good
+introduction to the topic.
    
+
+              		
+            
+          
+          
    
+            
+          
+            
+          
    package main
+
    
+          
    
+            
+          
+            
+          
    import (
+    "fmt"
+    "unicode/utf8"
+)
+
    
+          
    
+            
+          
+            
+          
    func main() {
+
    
+          
    
+            
    s is a string assigned a literal value
+representing the world “hello” in the Thai
+language. Go string literals are UTF-8
+encoded text.
    
+
+              		
+            
+          
    +    const s = "สวัสดี"
+
    
+          
    
+            
    Since strings are equivalent to []byte, this
+will produce the length of the raw bytes stored within.
    
+
+              		
+            
+          
    +    fmt.Println("Len:", len(s))
+
    
+          
    
+            
    Indexing into a string produces the raw byte values at
+each index. This loop generates the hex values of all
+the bytes that constitute the code points in s.
    
+
+              		
+            
+          
    +    for i := 0; i < len(s); i++ {
+        fmt.Printf("%x ", s[i])
+    }
+    fmt.Println()
+
    
+          
    
+            
    To count how many runes are in a string, we can use
+the utf8 package. Note that the run-time of
+RuneCountInString dependes on the size of the string,
+because it has to decode each UTF-8 rune sequentially.
+Some Thai characters are represented by multiple UTF-8
+code points, so the result of this count may be surprising.
    
+
+              		
+            
+          
    +    fmt.Println("Rune count:", utf8.RuneCountInString(s))
+
    
+          
    
+            
    A range loop handles strings specially and decodes
+each rune along with its offset in the string.
    
+
+              		
+            
+          
    +    for idx, runeValue := range s {
+        fmt.Printf("%#U starts at %d\n", runeValue, idx)
+    }
+
    
+          
    
+            
    We can achieve the same iteration by using the
+utf8.DecodeRuneInString function explicitly.
    
+
+              		
+            
+          
    +    fmt.Println("\nUsing DecodeRuneInString")
+    for i, w := 0, 0; i < len(s); i += w {
+        runeValue, width := utf8.DecodeRuneInString(s[i:])
+        fmt.Printf("%#U starts at %d\n", runeValue, i)
+        w = width
+
    
+          
    
+            
    This demonstrates passing a rune value to a function.
    
+
+              		
+            
+          
    +        examineRune(runeValue)
+    }
+}
+
    
+          
    
+            
+          
+            
+          
    func examineRune(r rune) {
+
    
+          
    
+            
    Values enclosed in single quotes are rune literals. We
+can compare a rune value to a rune literal directly.
    
+
+              		
+            
+          
    +    if r == 't' {
+        fmt.Println("found tee")
+    } else if r == 'ส' {
+        fmt.Println("found so sua")
+    }

    Starting with version 1.18, Go has added support for
+generics, also known as type parameters.
    
+
+              		
+            
+          
+          
    
+            
+          
+            
+          
    package main
+
    
+          
    
+            
+          
+            
+          
    import "fmt"
+
    
+          
    
+            
    As an example of a generic function, MapKeys takes
+a map of any type and returns a slice of its keys.
+This function has two type parameters - K and V;
+K has the comparable constraint, meaning that
+we can compare values of this type with the == and
+!= operators. This is required for map keys in Go.
+V has the any constraint, meaning that it’s not
+restricted in any way (any is an alias for interface{}).
    
+
+              		
+            
+          
    +func MapKeys[K comparable, V any](m map[K]V) []K {
+    r := make([]K, 0, len(m))
+    for k := range m {
+        r = append(r, k)
+    }
+    return r
+}
+
    
+          
    
+            
    As an example of a generic type, List is a
+singly-linked list with values of any type.
    
+
+              		
+            
+          
    +type List[T any] struct {
+    head, tail *element[T]
+}
+
    
+          
    
+            
+          
+            
+          
    type element[T any] struct {
+    next *element[T]
+    val  T
+}
+
    
+          
    
+            
    We can define methods on generic types just like we
+do on regular types, but we have to keep the type
+parameters in place. The type is List[T], not List.
    
+
+              		
+            
+          
    +func (lst *List[T]) Push(v T) {
+    if lst.tail == nil {
+        lst.head = &element[T]{val: v}
+        lst.tail = lst.head
+    } else {
+        lst.tail.next = &element[T]{val: v}
+        lst.tail = lst.tail.next
+    }
+}
+
    
+          
    
+            
+          
+            
+          
    func (lst *List[T]) GetAll() []T {
+    var elems []T
+    for e := lst.head; e != nil; e = e.next {
+        elems = append(elems, e.val)
+    }
+    return elems
+}
+
    
+          
    
+            
+          
+            
+          
    func main() {
+    var m = map[int]string{1: "2", 2: "4", 4: "8"}
+
    
+          
    
+            
    When invoking generic functions, we can often rely
+on type inference. Note that we don’t have to
+specify the types for K and V when
+calling MapKeys - the compiler infers them
+automatically.
    
+
+              		
+            
+          
    +    fmt.Println("keys m:", MapKeys(m))
+
    
+          
    
+            
    … though we could also specify them explicitly.
    
+
+              		
+            
+          
    +    _ = MapKeys[int, string](m)
+
    
+          
    
+            
+          
+            
+          
        lst := List[int]{}
+    lst.Push(10)
+    lst.Push(13)
+    lst.Push(23)
+    fmt.Println("list:", lst.GetAll())
+}
+
    
+          
    
+      
+

    We often need our programs to perform operations on
-collections of data, like selecting all items that
-satisfy a given predicate or mapping all items to a new
-collection with a custom function.

    In some languages it’s idiomatic to use generic
-data structures and algorithms. Go does not support
-generics; in Go it’s common to provide collection
-functions if and when they are specifically needed for
-your program and data types.

    Here are some example collection functions for slices
-of strings. You can use these examples to build your
-own functions. Note that in some cases it may be
-clearest to just inline the collection-manipulating
-code directly, instead of creating and calling a
-helper function.

    //go:embed is a compiler directive that allows programs to include arbitrary
+files/folders in the binary. Read more about go directive
+here.
    
+
+              		
+            
+          
    +package main
+
    
+          
    
+            
    If no exported identifiers is directly used from embed package,
+you can add an underscore _ before the package name. In this example, we simply
+import it as we need to use the embed.FS type from the package.
    
+
+              		
+            
+          
    +import (
+    //_ "embed"
+    "embed"
+)
+
    
+          
    
+            
    Since one file is defined after the directive, the compiler will only include
+this single file, followed by variable single_file_string to access as string type.
    
+
+              		
+            
+          
    +//go:embed example_folder/single_file.txt
+var single_file_string string
+
    
+          
    
+            
    Here is a similar example but include single file as []byte.
    
+
+              		
+            
+          
    +//go:embed example_folder/single_file.txt
+var single_file_byte []byte
+
    
+          
    
+            
    We can also embed multiple files or even folders with wildcard.
    
+
+              		
+            
+          
    +//go:embed example_folder/single_file.txt
+//go:embed example_folder/*.hash
+var folder_FS embed.FS
+
    
+          
    
+            
+          
+            
+          
    func main() {
+
    
+          
    
+            
    Print out content of example_single_file.txt as string.
    
+
+              		
+            
+          
    +    print(single_file_string)
+
    
+          
    
+            
    Now handle []byte.
    
+
+              		
+            
+          
    +    print(string(single_file_byte))
+
    
+          
    
+            
    Retrieve file(s) matching *.hash pattern by reading from variable folder_FS first,
+then print out.
    
+
+              		
+

Subject: [PATCH 159/283] Adjust for gofmt changes in 1.19

In 1.19, gofmt slightly changes how comments are formatted; a blank `//` is
inserted before `//go:embed` directives.

To accommodate for that in generate.go, treat empty comment lines as
part of docs segments.

    The Go standard library comes with excellent support
-for HTTP clients and servers in the net/http
-package. In this example we’ll use it to issue simple
-HTTP requests.

    Issue an HTTP GET request to a server. http.Get is a
-convenient shortcut around creating an http.Client
-object and calling its Get method; it uses the
-http.DefaultClient object which has useful default
-settings.

    Writing a basic HTTP server is easy using the
+net/http package.
    
+
+              		
+            
+          
    +package main
+
    
+          
    
+            
+          
+            
+          
    import (
+    "fmt"
+    "net/http"
+)
+
    
+          
    
+            
    A fundamental concept in net/http servers is
+handlers. A handler is an object implementing the
+http.Handler interface. A common way to write
+a handler is by using the http.HandlerFunc adapter
+on functions with the appropriate signature.
    
+
+              		
+            
+          
    +func hello(w http.ResponseWriter, req *http.Request) {
+
    
+          
    
+            
    Functions serving as handlers take a
+http.ResponseWriter and a http.Request as
+arguments. The response writer is used to fill in the
+HTTP response. Here our simple response is just
+“hello\n”.
    
+
+              		
+            
+          
    +    fmt.Fprintf(w, "hello\n")
+}
+
    
+          
    
+            
+          
+            
+          
    func headers(w http.ResponseWriter, req *http.Request) {
+
    
+          
    
+            
    This handler does something a little more
+sophisticated by reading all the HTTP request
+headers and echoing them into the response body.
    
+
+              		
+            
+          
    +    for name, headers := range req.Header {
+        for _, h := range headers {
+            fmt.Fprintf(w, "%v: %v\n", name, h)
+        }
+    }
+}
+
    
+          
    
+            
+          
+            
+          
    func main() {
+
    
+          
    
+            
    We register our handlers on server routes using the
+http.HandleFunc convenience function. It sets up
+the default router in the net/http package and
+takes a function as an argument.
    
+
+              		
+            
+          
    +    http.HandleFunc("/hello", hello)
+    http.HandleFunc("/headers", headers)
+
    
+          
    
+            
    Finally, we call the ListenAndServe with the port
+and a handler. nil tells it to use the default
+router we’ve just set up.
    
+
+              		
+            
+          
    +    http.ListenAndServe(":8090", nil)
+}
+
    
+          
    
+      
+      
+        
+        
+          
+          
+        
+        
+

+          
+        
+        
+      
    
+            
    Run the server in the background.
    
+
+              		
+            
+          
    +$ go run http-servers.go &
    
+          
    
+            
    Access the /hello route.
    
+
+

Subject: [PATCH 166/283] Minor addition to if-else text on declarations (#450)

* Minor addition to if-else text on declarations

Extremely minor addition to if-else text on declarations preceding conditionals, by explicitly clarifying that variables declared are only available in branches succeeding the declaration, not all the branches in the if-else ladder (i.e. preceding branches will not have it in their scope)

This edit might be redundant since variables in Golang can only be used after declaration, but to a complete novice the original wording of "...any variables declared in this statement are available in *all* branches..." might be a little misleading and appear to say that the variable is in-scope for the preceding branches as well (as this seems to be a very Golang-specific semantic that other high-level languages like C/C++, Java, Scala, Kotlin etc don't support; and so it will be a brand new paradigm for developers coming from such languages).

Thanks!

* Increment: Include changes in source .go file for #450

    The Go standard library provides straightforward
+tools for outputting logs from Go programs, with
+the log package for
+free-form output and the
+log/slog package for
+structured output.
    
+
+              		
+            
+          
    package main
    
+          
    
+            
+          
+            
+          
    import (
+    "bytes"
+    "fmt"
+    "log"
+    "os"
    
+          
    
+            
+          
+            
+          
        "log/slog"
+)
    
+          
    
+            
+          
+            
+          
    func main() {
    
+          
    
+            
    Simply invoking functions like Println from the
+log package uses the standard logger, which
+is already pre-configured for reasonable logging
+output to os.Stderr. Additional methods like
+Fatal* or Panic* will exit the program after
+logging.
    
+
+              		
+            
+          
        log.Println("standard logger")
    
+          
    
+            
    Loggers can be configured with flags to set
+their output format. By default, the standard
+logger has the log.Ldate and log.Ltime flags
+set, and these are collected in log.LstdFlags.
+We can change its flags to emit time with
+microsecond accuracy, for example.
    
+
+              		
+            
+          
        log.SetFlags(log.LstdFlags | log.Lmicroseconds)
+    log.Println("with micro")
    
+          
    
+            
    It also supports emitting the file name and
+line from which the log function is called.
    
+
+              		
+            
+          
        log.SetFlags(log.LstdFlags | log.Lshortfile)
+    log.Println("with file/line")
    
+          
    
+            
    It may be useful to create a custom logger and
+pass it around. When creating a new logger, we
+can set a prefix to distinguish its output
+from other loggers.
    
+
+              		
+            
+          
        mylog := log.New(os.Stdout, "my:", log.LstdFlags)
+    mylog.Println("from mylog")
    
+          
    
+            
    We can set the prefix
+on existing loggers (including the standard one)
+with the SetPrefix method.
    
+
+              		
+            
+          
        mylog.SetPrefix("ohmy:")
+    mylog.Println("from mylog")
    
+          
    
+            
    Loggers can have custom output targets;
+any io.Writer works.
    
+
+              		
+            
+          
        var buf bytes.Buffer
+    buflog := log.New(&buf, "buf:", log.LstdFlags)
    
+          
    
+            
    This call writes the log output into buf.
    
+
+              		
+            
+          
        buflog.Println("hello")
    
+          
    
+            
    This will actually show it on standard output.
    
+
+              		
+            
+          
        fmt.Print("from buflog:", buf.String())
    
+          
    
+            
    The slog package provides
+structured log output. For example, logging
+in JSON format is straightforward.
    
+
+

Subject: [PATCH 198/283] Update Atomic Counters example to use atomic.Uint64
 (#490)

* Update Atomic Counters example to use atomic.Uint64

This commit updates the Atomic Counters example to follow atomic's
recommendation of using atomic.Uint64 instead of uint64 (same for other
types) and then calling methods on it, instead of calling
atomic.AddUint64().

It also updates the comments and empty lines a bit to look better on the
website.

* Run tools/build again

* Fix comments

Subject: [PATCH 218/283] Darkmode style refactoring and tweaking

Refactoring:
* Refactor CSS to make clear what varies with light/dark mode and what doesn't.
* Consistently use 2 spaces for indenting in CSS file.
* Remove unused Chroma CSS classes to make styling easier to understand.
* Add some comments about how Chroma CSS classes map to Go code.
* Organize Chroma CSS classes so that like-styled classes are contiguous.
* Display "operators" like regular code - doesn't make sense to style ":="
  specially but not "=" e.g.

Style tweaks:
* Adjust dark mode styling to be less blue, more subdued.

Subject: [PATCH 222/283] Add wrapping errors (#517)

Fixes #334

* Add wrapping errors.

Before there was one page about error handling.

Now there are three.

A simple page (the first part of the existing page).

Then a new page about wrapping errors.

And the third page is the second half of the existing page (custom errors).

* ... addressed pr feedback.

* ./tools/build was run.

    errors.Is is a function in Go that checks if a given error

+allowing you to identify specific error types or sentinel errors in

+By using several if-statements we can handle
+different sentinel errors.

    Wrapping errors is a technique that allows you to add additional context
-to an error while preserving the original error.
-This approach is beneficial for debugging and understanding
-the chain of events that led to an error, especially in
-complex applications with multiple layers of function calls.

Subject: [PATCH 232/283] Stop breaking browser navigation shortcuts. (#527)

On Linux Chrome I use ALT + Arrows to go back in the browser, but instead
it paginates between examples.

Fixed it by checking for special key modifiers and do nothing (to the let the browser handle it).
I think the user always intends a system shortcut if they use a modifier key.

    Enumerated types (enums) are a special case of
+sum types.
+An enum is a type that has a fixed number of possible
+values, each with a distinct name. Go doesn’t have an
+enum type as a distinct language feature, but enums
+are simple to implement using existing language idioms.

    Our enum type ServerState has an underlying int type.
    
+
+              		
+            
+          
    type ServerState int
    
+          
    
+            
    The possible values for ServerState are defined as
+constants. The special keyword iota
+generates successive constant values automatically; in this
+case 0, 1, 2 and so on.
    
+
+              		
+            
+          
    const (
+    StateIdle = iota
+    StateConnected
+    StateError
+    StateRetrying
+)
    
+          
    
+            
    By implementing the fmt.Stringer
+interface, values of StateType can be printed out or converted
+to strings.
    
+
+
    This can get cumbersome if there are many possible values. In such
+cases the stringer tool
+can be used in conjunction with go:generate to automate the
+process. See this post
+for a longer explanation.
    
+
+              		
+            
+          
    var stateName = map[ServerState]string{
+    StateIdle:      "idle",
+    StateConnected: "connected",
+    StateError:     "error",
+    StateRetrying:  "retrying",
+}
    
+          
    
+            
+          
+            
+          
    func (ss ServerState) String() string {
+    return stateName[ss]
+}
    
+          
    
+            
    If we have a value of type int, we cannot pass it to transition - the
+compiler will complain about type mismatch. This provides some degree of
+compile-time type safety for enums.
    
+
+              		
+            
+          
    func main() {
+    ns := transition(StateIdle)
+    fmt.Println(ns)
    
+          
    
+            
+          
+            
+          
        ns2 := transition(ns)
+    fmt.Println(ns2)
+}
    
+          
    
+            
    transition emulates a state transition for a
+server; it takes the existing state and returns
+a new state.
    
+
+              		
+            
+          
    func transition(s ServerState) ServerState {
+    switch s {
+    case StateIdle:
+        return StateConnected
+    case StateConnected, StateRetrying:
    
+          
    
+            
    Suppose we check some predicates here to
+determine the next state…
    
+
+              		
+            
+          
            return StateIdle
+    case StateError:
+        return StateError
+    default:
+        panic(fmt.Errorf("unwknown state: %s", s))
+    }

-This function has two type parameters - K and V;
-K has the comparable constraint, meaning that
-we can compare values of this type with the == and
-!= operators. This is required for map keys in Go.
-V has the any constraint, meaning that it’s not

        Starting with version 1.23, Go has added support for
+iterators,
+which lets us range over custom types.
        
+
+                  		
+            
+          
+          
        
+            
+          
+            
+          
        package main
        
+          
        
+            
+          
+            
+          
        import (
+    "fmt"
+    "iter"
+    "slices"
+)
        
+          
        
+            
        Let’s look at the List type from the
+previous example again. In that example
+we had an AllElements method that returned a slice
+of all elements in the list. With Go iterators, we
+can do it better - as shown below.
        
+
+                  		
+            
+          
        type List[T any] struct {
+    head, tail *element[T]
+}
        
+          
        
+            
+          
+            
+          
        type element[T any] struct {
+    next *element[T]
+    val  T
+}
        
+          
        
+            
+          
+            
+          
        func (lst *List[T]) Push(v T) {
+    if lst.tail == nil {
+        lst.head = &element[T]{val: v}
+        lst.tail = lst.head
+    } else {
+        lst.tail.next = &element[T]{val: v}
+        lst.tail = lst.tail.next
+    }
+}
        
+          
        
+            
        All returns an iterator, which in Go is a function
+with a special signature.
        
+
+                  		
+            
+          
        func (lst *List[T]) All() iter.Seq[T] {
+    return func(yield func(T) bool) {
        
+          
        
+            
        The iterator function takes another function as
+a parameter, called yield by convention (but
+the name can be arbitrary). It will call yield for
+every element we want to iterate over, and note yield’s
+return value for a potential early termination.
        
+
+                  		
+            
+          
                for e := lst.head; e != nil; e = e.next {
+            if !yield(e.val) {
+                return
+            }
+        }
+    }
+}
        
+          
        
+            
+          
+            
+          
        func main() {
+    lst := List[int]{}
+    lst.Push(10)
+    lst.Push(13)
+    lst.Push(23)
        
+          
        
+            
        Since List.All returns an interator, it can be used
+in a regular range loop!
        
+
+                  		
+            
+          
            for e := range lst.All() {
+        fmt.Println(e)
+    }
        
+          
        
+            
        Packages like slices have
+a number of useful functions to work with iterators.
+For example, Collect takes any iterator and collects
+all its values into a slice.
        
+
+                  		
+            
+          
            all := slices.Collect(lst.All())
+    fmt.Println("all:", all)
+}
        
+          
        
+      
+      
+        
+        
+          
+          
+        
+        
+      
        
+            
+          
+            
+          
        10
+13
+23
+all: [10 13 23]
        
+          
        
+      
+      
+      
        
+        Next example: Errors.
