Local Development

Prerequisites

To develop the site locally, you will need to get the following dependencies:

• Ruby
• Bundler (gem install bundler)

For Bundler, depending on your system, you may need to also install the Ruby development headers (e.g. ruby-dev). On Ubuntu/Debian, for example, this would be accomplished by doing sudo apt-get install ruby-dev.

Setup

1. Clone the respository on your local machine, e.g.,

   git clone https://github.com/Submitty/submitty.github.io.git
   

   • NOTE: We recommend placing the code in a directory/folder on your machine without spaces, because some developers have experienced errors with bundler when the full path contained spaces.

2. Use Bundler to install the dependencies. This can be accomplished by running:

   bundle install

   • NOTE: During the install, it may hang up when installing the dependency nokogiri. Don't worry: continue waiting. If it still is stalling here, press enter and it should continue.

   • NOTE: If an error is thrown during the installation process you may need to downgrade from 3.0 to use Ruby-2.7 and make sure this is indeed the version that the Bundler is using and not another one in a different directory.

Running the Site

• To view the site locally, and the results of any changes you make, you will want to use the jekyll commands through Bundler, namely the serve sub-command, as shown below:

  bundle exec jekyll serve

• NOTE: If you have an error running on the default port (4000), you can specify an alternate port, e.g.

  bundle exec jekyll serve --port 4001

• If you wish to build the site locally instead of running it, you can do:

  bundle exec jekyll build

  which will leave the results in a _site directory.

Running the link checker

GitHub Actions checks each pull request for broken links using the htmlproofer package. If you wish to run htmlproofer locally, cd into the submitty.github.io repository and run the command:

bundle exec htmlproofer ./_site --assume-extension --empty-alt-ignore --disable_external

Editing Content

The site's content is defined with markdown files under the docs/ folder, where then it's separated by a couple of high-level sections (student, instructor, sysadmin, developer). For any new page, a new entry must be added to the navigation manually (see below). The rendered markdown uses a variant of Github Flavored Markdown. For every page, it should have a front-matter block at the top of the file that has minimally:

---
title: Page Title
---

where this is used as the main header title on the page, as well as for the title of the page in the browser. You should then not include a # Page Title in the file, rather just start your content immediately after the front-matter block.

Navigation

Editing the links on the navigation is done by editing navtreedata.js. The structure of the file is that each level is a list of objects, where the object can have the following parts:

• name (required)
• link
• children

Where if link is omitted, then name will be used where it will be lowercased and spaced replaced with _. Children is then a list of objects of the above structure. Currently, the site only supports three levels of nesting (sub-sub-children).

Search

• Add excluded_in_search: true to any documentation page's front matter to exclude that page in the search results.
