Course website

This site serves courses that reside in a git repo consisting of mostly Markdown-formatted text files and any other source files that should be served to the students. The code is targeted towards Rails 6.1.

How to install

Clone the application:

git clone git@github.com:uva/course-site.git
bundle install
rails db:schema:load

You can now claim the site by authenticating, and then load the initial content by specifiying a git repository URL that can be cloned.

Alternatively, you can clone the course contents yourself, into the public/course directory:

cd public
git clone <course-url> course

On the source format

Have a look at https://github.com/minprog/platforms for information on how to organize your course repository. At the very least, you need a course.yml and a info directory containing subpages for the homepage.
Numbering the course folders will make sure that they are imported and displayed in order. Any folders besides info that are not numbered will not be imported.
Small non-markdown files, like images or downloads, will be hosted directly in the public directory and can be referenced using relative links.
Changing the name of a folder will change the URL of that folder on the website. This will break links from other sites to your course site.
Changing names and positions of folders and Markdown files should not be a problem for form caching and file submissions already done.

Formatting your pages

All pages are to be formatted with Markdown and the Kramdown extensions.
You can use AsciiMath or LaTeX if enclosed within pairs of dollar signs ($$sin(x)$$, or $sin(x)$ for inlined math). Check the AsciiMath syntax.
Add a table of contents to a page using:
```
  * Table of Contents
  {:toc}
```
This single bullet item is then replaced with a full table of contents of level 1 and 2 headings.

Admin configuration options

Setting a CAS_BASE_URL is needed for authentication using CAS (the only option). In development, a "fake" login screen is used which accepts any username.
Setting a MAILER_ADDRESS and MAILER_DOMAIN will allow mails to be sent to users.
