Make sure you follow the issue template. - * It's important that we can consistently reproduce issues. When writing an issue, be sure to follow our [reproduction step guidelines](https://github.com/LLK/scratch-gui/wiki/Writing-good-repro-steps). - * Some issues are marked "Needs Repro". Adding a comment with good reproduction steps to those issues is a great way to help. - * If you don't have an issue in mind already, you can look through the [Bugs & Glitches forum.](https://scratch.mit.edu/discuss/3/) Look for users reporting problems, reproduce the problem yourself, and file new issues following our guidelines. - -* **Fixing bugs** - * You can request to fix a bug in a comment on the issue if you at mention the repo coordinator, who for this repo is @ericrosenbaum. - * If the issue is marked "Help Wanted" you can go ahead and start working on it! - * **We will only accept Pull Requests for bugs that have an issue filed that has a priority label** - * If you're interested in fixing a bug with no issue, file the issue first and wait for it to have a priority added to it. - - * We are not looking for Pull Requests ("PR") for every issue and may deny a PR if it doesn't fit our criteria. - * We are far more likely to accept a PR if it is for an issue marked with Help Wanted. - * We will not accept PRs for issues marked with "Needs Discussion" or "Needs Design." - * Wait until the Repo Coordinator assigns the issue to you before you begin work or submit a PR. - -### Learning Git and Github - -If you want to work on fixing issues, you should be familiar with Git and Github. - -* [Learn Git branching](https://learngitbranching.js.org/) includes an introduction to basic git commands and useful branching features. -* Here's a general introduction to [contributing to an open source project](https://egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github). - -**Important:** we follow the [Github Flow process](https://guides.github.com/introduction/flow/) as our development process. - -### How to Fix Bugs -1.

If such support is needed, it can be added. + * + * Example Usage: + * + * var asyncTestCase = goog.testing.AsyncTestCase.createAndInstall(); + * // Optionally, set a longer-than-normal step timeout. + * asyncTestCase.stepTimeout = 30 * 1000; + * + * function testSetTimeout() { + * var step = 0; + * function stepCallback() { + * step++; + * switch (step) { + * case 1: + * var startTime = goog.now(); + * asyncTestCase.waitForAsync('step 1'); + * window.setTimeout(stepCallback, 100); + * break; + * case 2: + * assertTrue('Timeout fired too soon', + * goog.now() - startTime >= 100); + * asyncTestCase.waitForAsync('step 2'); + * window.setTimeout(stepCallback, 100); + * break; + * case 3: + * assertTrue('Timeout fired too soon', + * goog.now() - startTime >= 200); + * asyncTestCase.continueTesting(); + * break; + * default: + * fail('Unexpected call to stepCallback'); + * } + * } + * stepCallback(); + * } + * + * Known Issues: + * IE7 Exceptions: + * As the failingtest.html will show, it appears as though ie7 does not + * propagate an exception past a function called using the func.call() + * syntax. This causes case 3 of the failing tests (exceptions) to show up + * as timeouts in IE. + * window.onerror: + * This seems to catch errors only in ff2/ff3. It does not work in Safari or + * IE7. The consequence of this is that exceptions that would have been + * caught by window.onerror show up as timeouts. + * + * @author agrieve@google.com (Andrew Grieve) + */ + +goog.setTestOnly('goog.testing.AsyncTestCase');

This is ideal for most tests, but makes it difficult to test + * routines that require real time to complete. The tests and TestCase in this + * file allow for tests that can wait until a condition is true before + * continuing execution. + * + * Each test has the typical three phases of execution: setUp, the test itself, + * and tearDown. During each phase, the test function may add wait conditions, + * which result in new test steps being added for that phase. All steps in a + * given phase must complete before moving on to the next phase. An error in + * any phase will stop that test and report the error to the test runner. + * + * This class should not be used where adequate mocks exist. Time-based routines + * should use the MockClock, which runs much faster and provides equivalent + * results. Continuation tests should be used for testing code that depends on + * browser behaviors that are difficult to mock. For example, testing code that + * relies on Iframe load events, event or layout code that requires a setTimeout + * to become valid, and other browser-dependent native object interactions for + * which mocks are insufficient. + * + * Sample usage: + * + * 
+ * var testCase = new goog.testing.ContinuationTestCase();

+ * In the simplest cases, the behavior that the developer wants to test + * is synchronous, and the test functions exercising the behavior execute + * synchronously. But TestCase can also be used to exercise asynchronous code + * through the use of + * promises. If a test function returns an object that has a + * then method defined on it, the test framework switches to an + * asynchronous execution strategy: the next test function will not begin + * execution until the returned promise is resolved or rejected. Instead of + * writing test assertions at the top level inside a test function, the test + * author chains them on the end of the returned promise. For example: + *

+ * 
+ *   function testPromiseBasedAPI() {
+ *     return promiseBasedAPI().then(function(value) {
+ *       // Will run when the promise resolves, and before the next
+ *       // test function begins execution.
+ *       assertEquals('foo', value.bar);
+ *     });
+ *   }
+ *
+ *

+ * Synchronous and asynchronous tests can be mixed in the same TestCase. + * Test functions that return an object with a then method are + * executed asynchronously, and all other test functions are executed + * synchronously. While this is convenient for test authors (since it doesn't + * require any explicit configuration for asynchronous tests), it can lead to + * confusion if the test author forgets to return the promise from the test + * function. For example: + *

+ * 
+ *   function testPromiseBasedAPI() {
+ *     // This test should never succeed.
+ *     promiseBasedAPI().then(fail, fail);
+ *     // Oops! The promise isn't returned to the framework,
+ *     // so this test actually does succeed.
+ *   }
+ *
+ *

+ * Since the test framework knows nothing about the promise created + * in the test function, it will run the function synchronously, record + * a success, and proceed immediately to the next test function. + *

+ *

+ * Promises returned from test functions can time out. If a returned promise + * is not resolved or rejected within {@link promiseTimeout} milliseconds, + * the test framework rejects the promise without a timeout error message. + * Test cases can configure the value of `promiseTimeout` by setting + * 

+ *   goog.testing.TestCase.getActiveTestCase().promiseTimeout = ...
+ *

      The system continually sends TouchEvent objects to an application as\\n * fingers touch and move across a surface. A touch event provides a snapshot of\\n * all touches during a multi-touch sequence, most importantly the touches that\\n * are new or have changed for a particular target. A multi-touch sequence\\n * begins when a finger first touches the surface. Other fingers may\\n * subsequently touch the surface, and all fingers may move across the surface.\\n * The sequence ends when the last of these fingers is lifted from the surface.\\n * An application receives touch event objects during each phase of any touch.\\n *

      \\n *\\n *

      The different types of TouchEvent objects that can occur are:\\n *

        \\n *
      • touchstart - Sent when a finger for a given event touches the surface.\\n *
      • touchmove - Sent when a given event moves on the surface.\\n *
      • touchend - Sent when a given event lifts from the surface.\\n *
      • touchcancel - Sent when the system cancels tracking for the touch.\\n *
      \\n * TouchEvent objects are combined together to form high-level GestureEvent\\n * objects that are also sent during a multi-touch sequence.

+ * @fileoverview Definitions for all tweak entries.
+ * The class hierarchy is as follows (abstract entries are denoted with a *):
+ * BaseEntry(id, description) *
+ *   -> ButtonAction(buttons in the UI)
+ *   -> BaseSetting(query parameter) *
+ *     -> BooleanGroup(child booleans)
+ *     -> BasePrimitiveSetting(value, defaultValue) *
+ *       -> BooleanSetting
+ *       -> StringSetting
+ *       -> NumericSetting
+ *       -> BooleanInGroupSetting(token)
+ * Most clients should not use these classes directly, but instead use the API
+ * defined in tweak.js. One possible use case for directly using them is to
+ * register tweaks that are not known at compile time.

+/**
+ * @fileoverview Abstract base class for spell checker implementations.
+ *
+ * The spell checker supports two modes - synchronous and asynchronous.
+ *
+ * In synchronous mode subclass calls processText_ which processes all the text
+ * given to it before it returns. If the text string is very long, it could
+ * cause warnings from the browser that considers the script to be
+ * busy-looping.
+ *
+ * Asynchronous mode allows breaking processing large text segments without
+ * encountering stop script warnings by rescheduling remaining parts of the
+ * text processing to another stack.
+ *
+ * In asynchronous mode abstract spell checker keeps track of a number of text
+ * chunks that have been processed after the very beginning, and returns every
+ * so often so that the calling function could reschedule its execution on a
+ * different stack (for example by calling setInterval(0)).

+ * - Mac     x {FF3, Safari3}     x Kotoeri (Japanese)
+ * - Linux   x {FF3}              x UIM + Anthy (Japanese)
+ *
+ * TODO(user): We cannot handle {Mac, Linux} x FF3 correctly.
+ * TODO(user): We need to support Windows x Google IME.
+ *
+ * This class was tested with hiragana input. The event sequence when inputting
+ * 'ai' with IME on (which commits two characters) is as follows:
+ *
+ * Notation: [key down code, key press, key up code]
+ *           key code or +: event fired
+ *           -: event not fired
+ *
+ * - Win/FF3: [WIN_IME, +, A], [-, -, ENTER]
+ *            Note: No events are fired for 'i'.
+ *
+ * - Win/IE7: [WIN_IME, -, A], [WIN_IME, -, I], [WIN_IME, -, ENTER]
+ *
+ * - Win/Chrome: Same as Win/IE7
+ *
+ * - Mac/FF3: [A, -, A], [I, -, I], [ENTER, -, ENTER]
+ *
+ * - Mac/Safari3: Same as Win/IE7
+ *
+ * - Linux/FF3: No events are generated.
+ *
+ * With IME off,
+ *
+ * - ALL: [A, +, A], [I, +, I], [ENTER, +, ENTER]
+ *        Note: Key code of key press event varies across configuration.
+ *
+ * With Microsoft Pinyin IME 3.0 (Simplified Chinese),
+ *
+ * - Win/IE7: Same as Win/IE7 with MS IME 2002 (Japanese)
+ *
+ *   The issue with this IME is that the key sequence that ends preedit is not
+ *   a single ENTER key up.
+ *   - ENTER key up following either ENTER or SPACE ends preedit.
+ *   - SPACE key up following even number of LEFT, RIGHT, or SPACE (any
+ *     combination) ends preedit.
+ *   TODO(user): We only support SPACE-then-ENTER sequence.
+ *   TODO(mpd): With the change to autocomplete during IME, this might not be an
+ *   issue. Remove this comment once tested.
+ *
+ * With Microsoft Korean IME 2002,
+ *
+ * - Win/IE7: Same as Win/IE7 with MS IME 2002 (Japanese), but there is no
+ *   sequence that ends the preedit.
+ *
+ * The following is the algorithm we use to detect IME preedit:
+ *
+ * - WIN_IME key down starts predit.
+ * - (1) ENTER key up or (2) CTRL-M key up ends preedit.
+ * - Any key press not immediately following WIN_IME key down signifies that
+ *   preedit has ended.
+ *
+ * If you need to change this algorithm, please note the OS, browser, language,
+ * and behavior above so that we can avoid regressions. Contact mpd or yuzo
+ * if you have questions or concerns.

+/**
+ * @fileoverview Tree-like drilldown components for HTML tables.
+ *
+ * This component supports expanding and collapsing groups of rows in
+ * HTML tables.  The behavior is like typical Tree widgets, but tables
+ * need special support to enable the tree behaviors.
+ *
+ * Any row or rows in an HTML table can be DrilldownRows.  The root
+ * DrilldownRow nodes are always visible in the table, but the rest show
+ * or hide as input events expand and collapse their ancestors.
+ *
+ * Programming them:  Top-level DrilldownRows are made by decorating
+ * a TR element.  Children are made with addChild or addChildAt, and
+ * are entered into the document by the render() method.
+ *
+ * A DrilldownRow can have any number of children.  If it has no children
+ * it can be loaded, not loaded, or with a load in progress.
+ * Top-level DrilldownRows are always displayed (though setting
+ * style.display on a containing DOM node could make one be not
+ * visible to the user).  A DrilldownRow can be expanded, or not.  A
+ * DrilldownRow displays if all of its ancestors are expanded.
+ *
+ * Set up event handlers and style each row for the application in an
+ * enterDocument method.
+ *
+ * Children normally render into the document lazily, at the first
+ * moment when all ancestors are expanded.
+ *
+ * @see ../demos/drilldownrow.html
+ */
+
+// TODO(user): Build support for dynamically loading DrilldownRows,
+// probably using automplete as an example to follow.
+
+// TODO(user): Make DrilldownRows accessible through the keyboard.
+
+// The render method is redefined in this class because when addChildAt renders
+// the new child it assumes that the child's DOM node will be a child
+// of the parent component's DOM node, but all DOM nodes of DrilldownRows
+// in the same tree of DrilldownRows are siblings to each other.
+//
+// Arguments (or lack of arguments) to the render methods in Component
+// all determine the place of the new DOM node in the DOM tree, but
+// the place of a new DrilldownRow in the DOM needs to be determined by
+// its position in the tree of DrilldownRows.

+ * Creates a new, empty emoji picker. An emoji picker is a grid of emoji, each

+ * picker fires a goog.ui.Component.EventType.ACTION event with the id. The

+ * is, once an emoji is selected, the emoji picker does not remember which emoji
+ * was selected.
