Surrounds two or more consecutive capital letters, perhaps with interspersed digits and periods in a span with a styled class. Typogruby cap module doesn't support having hyphens so there is a custom module. Converts special characters (excluding HTML tags) to HTML entities. Encloses initial single or double quotes, or their entities (optionally preceded by a block element and perhaps an inline element) with a span that can be styled. Applies smartpants to a given piece of text.

Gantry Framework
Next Generation Template / Theme Framework
Develop CMS themes quickly and efficiently while providing flexibility and ease of use for end-users. Gantry was born when the RocketTheme development team wanted to consolidate our extensive set of custom Grav, Joomla and WordPress theme functionality into a simple, easy-to-use framework. Yes, that’s right! Gantry 5 has a powerful and easy-to-use Layout Manager that ensures controlling the layout is a highly visual experience. When we started the Gantry 5 project, we wanted to think past the concept of Gantry as a framework. We wanted to create something so versatile and powerful, that it could stand on its own as a platform, virtually independent of a CMS in concept and implementation. Utilizing a dual MIT & GPL license, Gantry is free to use pretty much anywhere! Designed from the ground-up with performance and efficiency in mind. Configure and structure your menu hierarchy with our new Menu editor. -

Jekyll Readme Index
A Jekyll plugin to render a project's README as the site's index
A Jekyll plugin to render a project's README as the site's index. Let's say you have a GitHub repository with a README.md file, that you'd like to use as the index (main page) for a GitHub Pages site. You could rename the file to index.md, but then it wouldn't render on GitHub.com. You could add YAML front matter with permalink: / to the README, but why force a human to do what Jekyll can automate? If you have a readme file, and your site doesn't otherwise have an index file, this plugin instructs Jekyll to use the readme as the site's index. That's it, no more, no less. -

Jekyll Optional Front Matter
A Jekyll plugin to make front matter optional for Markdown files
A Jekyll plugin to make front matter optional for Markdown files. Out of the box, Jekyll requires that any markdown file have YAML front matter (key/value pairs separated by two sets of three dashes) in order to be processed and converted to HTML. While that behavior may be helpful for large, complex sites, sometimes it's easier to simply add a plain markdown file and have it render without fanfare. This plugin does just that. Any Markdown file in your site's source will be treated as a Page and rendered as HTML, even if it doesn't have YAML front matter. -

Timber themes
Create WordPress themes with OOP code and the Twig template engine
Timber helps you create fully-customized WordPress themes faster with more sustainable code. With Timber, you write your HTML using the Twig Template Engine separate from your PHP files.

Once Timber is installed and activated in your plugins directory, it gives any WordPress theme the ability to take advantage of the power of Twig and other Timber features. The GitHub version of Timber requires Composer and is setup for inclusion within a theme or plugin. If you'd prefer one-click installation for your site, you should use the WordPress.org version. Timber is great for any WordPress developer who cares about writing good, maintainable code. It helps teams of designers and developers working together. -
