    Minimal authorization through OO design and pure Ruby classes

    Pundit (varvet/pundit) is a Ruby gem that provides a simple and effective framework for adding authorization logic to Rails (or other Ruby) applications.

    RSpec Rails brings the RSpec testing framework to Ruby on Rails as a drop-in alternative to its default testing framework, Minitest. In RSpec, tests are not just scripts that verify your application code. They’re also specifications (or specs, for short): detailed explanations of how the application is supposed to behave, expressed in plain English. RSpec follows semantic versioning, which means that “major version” upgrades (e.g., 2.x → 3.x) come with breaking changes. If you’re upgrading...

    Slim is a Ruby template language whose goal is reduce the syntax to the essential parts without becoming cryptic. The initial design of Slim is what you see on the home page. It started as an exercise to see how much could be removed from a standard html template (<, >, closing tags, etc.). As more people took an interest in Slim, the functionality grew and so did the flexibility of the syntax. Slim will strive to maintain simplicity, but not everyone's definition of a readable syntax is the...

    Jekyll Pure Liquid Table of Contents

    Jekyll Pure Liquid Table of Contents

    A GitHub Pages compatible Table of Contents generator

    GitHub Pages can't run custom Jekyll plug-ins so when generating Tables of Contents (TOCs), you're stuck with either a JavaScript solution or using kramdown's {:toc} option. However, by using {:toc}, you are forced to have that code next to your actual markdown and you can't place it in a layout. This means every. single. post. will need to have the snippet. If you choose the JavaScript approach, that's perfectly fine but what if JS is disabled on someone's browser or your page is just...
