Hematite

Hematite is a work-in-progress Jekyll theme distributed as the "hematite" Ruby gem, built specifically for course websites and featuring a dark calendar view in its screenshot. It installs like any Jekyll gem theme and renders your site content through its own layouts, includes, Sass files, and assets.

What is Hematite?

Hematite is a Jekyll theme packaged as a Ruby gem, intended for course websites. It takes standard Jekyll site content — pages, posts, and data files — and outputs a static site using the theme's layouts and styles. The theme is maintained by personalizedrefrigerator, is released under the MIT License, and is marked as a work-in-progress with minimal documentation currently available.

Key Features

• Gem-based install — Add gem "hematite" to your Jekyll site's Gemfile, set theme: hematite in _config.yml, and run bundle to activate the theme.
• Course website focus — The theme is explicitly intended for course websites; its screenshot shows a dark variant with a calendar view.
• Standard Jekyll structure — Uses the conventional _layouts, _includes, _sass, and assets directories; only Git-tracked files in those directories are bundled into the released gem.
• Localization-ready strings — User-facing text lives in assets/string_data so the theme can be localized later.
• MIT License — The theme is open source and freely usable, with the license available at https://opensource.org/licenses/MIT.
• Local development workflow — Run bundle install and bundle exec jekyll serve to preview changes at http://localhost:4000.

Who is it for?

• Course instructors — Publish a static course website with a calendar for schedules and deadlines.
• Jekyll users — Developers who prefer the Ruby gem theme workflow and want a base to customize with their own layouts and assets.
• Educators using GitHub Pages — Host a course site on GitHub Pages using a gem-based Jekyll theme without managing a full custom theme from scratch.

What can you do with Hematite?

• Assemble a course site — Add pages, documents, and data to a Jekyll project and let Hematite's layouts render them consistently.
• Display a calendar view — The dark variant screenshot indicates a calendar-oriented design that can be used to show class dates and assignment due dates.
• Prepare for translation — Edit the string data files under assets/string_data to adapt visible text for different languages.

How does Hematite work?

After adding the gem to your Gemfile and setting theme: hematite, run bundle to install it. Your Jekyll site then uses Hematite's layouts and assets automatically. During development, bundle exec jekyll serve regenerates the site on changes, and you can view the result at http://localhost:4000.
