MIT License
Hosted MIT License with details controlled through this repo
The MIT License repository is a simple GitHub project that hosts the full text of the MIT License and provides a stable reference for developers who want to include permissive licensing details in their work. The MIT License itself is one of the most widely used open-source licenses because it allows reuse, modification, distribution, and even proprietary use, as long as copyright notices and license texts are preserved. This repository offers an easy way to copy the license text, understand its legal language, and see example usage in a context that is separate from any specific software project. It can also be useful for automated tooling and templates where a standard license file is needed across multiple repositories or as part of a code generation process. While not a software library or application, the repository serves an important role in open-source governance by centralizing a commonly adopted license with clear formatting. -

Magic Python
Cutting edge Python syntax highlighter for Sublime Text
This is a package with preferences and syntax highlighter for cutting edge Python 3, although Python 2 is well supported, too. The syntax is compatible with Sublime Text, Atom and Visual Studio Code. It is meant to be a drop-in replacement for the default Python package. Attention VSCode users, MagicPython is used as the default Python highlighter in Visual Studio Code. Don't install it unless you want or need the cutting-edge version of it. You will likely see no difference because you're already using MagicPython. MagicPython correctly highlights all Python 3 syntax features, including type annotations, f-strings and regular expressions. It is built from scratch for robustness with an extensive test suite. Type hints in comments require support by the color scheme. The main motivation behind this package was the difficulty of using modern Python with other common syntax highlighters. -

Masonry
A cascading grid layout plugin
Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. tem sizes can be set with percentages for responsive layouts. With the masonry layout mode, set percentage-width columnWidth with element sizing. Set percentPosition: true so item positions are likewise set with percentages to reduce adjustment transitions on window resize. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com. Or, initialize Masonry after all images have been loaded. -

A jQuery plugin that switches between multiple header designs as you scroll, so you always have a header that looks great with the content below it. Create your fixed nav (or header) as you typically would. Create your fixed nav (or header) as you typically would. You can use whatever markup suits you, just make sure the header works well with position:fixed. After that, take any sections of your page that need a different nav and add data-midnight="your-class" to it, where .your-class is the class you are going to use to style that header. If you don't use the property or just leave it blank, the .default class will be used for that section. You can style it in your CSS using the class .midnightHeader.your-class. Use whatever CSS or markup you like for each one. They will be switched automatically when necessary. To make everything work, just load midnight (and jQuery) and initialize it. We take care of the rest. -

MkDocs Jekyll Theme
The Material theme from MkDocs provided as a Jekyll template
This is a starter template for a MkDocs Jekyll theme. GitHub pages uses Jekyll natively, so when I make documentation, I typically look for Jekyll templates. Why? Using Jekyll means that I can use markdown, and allow for users to easily contribute, and build automatically just by way of pushing to a master branch (or general GitHub pages). I’ve liked MkDocs in the past, but it required me to use a special renderer. I also felt limited in my ability to customize it. The same is true for MkDocs material. It’s absolutely gorgeous, but was not suited for my GitHub pages and customization needs. For this reason, I’ve spent some time creating a custom Jekyll template that is (almost) as beautiful and includes all the features that I might want. -
