typelevel website

This is the website of typelevel.scala. It is built on Jekyll and served at typelevel.org.

Getting Started (the short version)

If you just want to add a blog post or fix a typo in the content, here's how to get started.

Creating a blog post

1. Create a new file in the ./collections/_posts directory or copy an existing post. Its name should have the format YYYY-MM-DD-short_title.md.
2. Set the title (short title of the post, appears as the HTML <title>) and author (your GitHub user name) in the front matter. MathJax is available via mathjax: true inside the front matter.
3. If this is your first blog post, please indicate if you want your name and a profile picture to appear on the post. If not, you can remove the author field from the front matter. Add your details in _data/authors.yml.
4. Write your content using Markdown. For code highlighting, use the usual GitHub syntax:

def yourCode: Here

If you haven't written a post before, please add yourself to _data/authors.yml.

That's it, we'll take care of the rest. If you wish, you can also submit just a plain Markdown file and we'll be happy to integrate it.

Previewing your changes

Bundler

To preview your changes, you have to install Bundler first. To download and set up all necessary dependencies, run

$ bundle install
... lots of text ...
Bundle complete! 1 Gemfile dependency, 81 gems now installed.
Bundled gems are installed into `./vendor/bundle`

Then, you can generate the site by running

$ bundle exec jekyll serve -wl --baseurl ''

The generated site will end up in the _site directory.

Nix

A fully configured Jekyll is available as a Nix app. Assumes that you have installed Nix and enabled flakes. You may optionally use the Typelevel Cachix.

$ nix run github:typelevel/typelevel.github.com#jekyll build

Development

CSS

The stylesheets are written in SASS, and can be found in the css and _sass directories. It is being processed/compiled into regular CSS by Jekyll.

├── css/
│   ├── main.scss # Custom CSS, brings all stylesheets together
├── _sass/
│   ├── base/
│   ├── components/
│   ├── utils/

Javascript

Javascript can be found in the js/ folder, which also includes its dependencies.

Templates

All templates/layouts can be found in the _layouts folder, except the blog layout, which is located inside its own subfolder blog/.

Images

Images for styling purposes are located inside img/, photos inside img/media/.

Adding a project

There are three types of projects: organization projects, affiliate projects, and core/featured projects.

To add an organization project, insert a new entry, alphabetically, in the _data/projects.yml file with the following keys:

- title: "Cats"
  description: "A library intended to provide abstractions for functional programming in Scala, leveraging its unique features. Design goals are approachability, modularity, documentation and efficiency."
  github: "https://github.com/typelevel/cats"
  platforms: [js, jvm, native]
  permalink: "https://typelevel.org/cats/" # optional

Right now nothing more than the correct front matter is required.

To add

• an affiliate project, add affiliate: true to the project entry
• a core project, add core: true to the project entry

Adding a page

To add a page,

1. Create a directory in the root of the project, with at least an index.html file in that directory.
2. Update _data/nav.yml to add it to the navigation. (The site navigation is not fully dynamic for simplification.)

Sample front matter for a page:

layout: page
title: "Code of Conduct"

Help, CI is failing on a Dependabot PR

We need to update the gemset as well.

nix run nixpkgs#bundix
git commit -am "Update gemset"
