Pretzel
A site generation tool (and then some) for .NET platforms
A simple, pluggable site generation tool for .NET developers and Windows users (with Mono support planned I think).

By using taste, Pretzel reprocesses your changes and spits out HTML on the fly. While Ruby is great, sometimes you care more about creating your website than installing Ruby, Ruby Dev Kit, Jekyll, and the other half-dozen requirements. Pretzel is a single exe. -

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. This cleans up your theme code so, for example, your PHP file can focus on being the data/logic, while your Twig file can focus 100% on the HTML and display. 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. -

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::Gzip
Generate gzipped assets and files for your Jekyll site at build time
Generate gzipped assets and files for your Jekyll site at build time. Performance in web applications is important. You know that, which is why you have created a static site using Jekyll. But you want a bit more performance. You're serving your assets and files gzipped, but you're making your webserver do it? Why not just generate those gzip files at build time? And with the maximum compression too? Jekyll::Gzip does just that. Add the gem to your Jekyll application and when you build your site it will generate gzip files for all text based files (HTML, CSS, JavaScript, etc). Zlib's gzipping capabilities don't quite squeeze all the compression out of our files that we could want. If you want a slower but better compression algorithm, check out Jekyll::Zopfli. Zopfli is about the best compression we can get out of the gzip format, but there's more! Brotli is a relatively new compression format that is now supported by many browsers and can produce even smaller files. -

Jekyll::Typogrify
A Jekyll plugin that improves the typography of your Liquid templates
Improves typography on your Jekyll site using typogruby, titlecase, and some other useful functions. Converts an ampersand (ex. &) converts a & surrounded by optional whitespace or a non-breaking space to the HTML entity and surrounds it in a span with a styled class. 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. Replaces space(s) before the last word (or tag before the last word) before an optional closing element (a, em, span, strong) before a closing tag (p, h[1-6], li, dt, dd) or the end of the string. -

Minify
Go minifiers for web formats
Minify is a minifier package written in Go. It provides HTML5, CSS3, JS, JSON, SVG and XML minifiers and an interface to implement any other minifier. Minification is the process of removing bytes from a file (such as whitespace) without changing its output and therefore shrinking its size and speeding up transmission over the internet and possibly parsing. The implemented minifiers are designed for high performance. The core functionality associates mime-types with minification functions, allowing embedded resources (like CSS or JS within HTML files) to be minified as well. Users can add new implementations that are triggered based on a mime-type (or pattern) or redirect to an external command (like ClosureCompiler, UglifyCSS,). Minifiers or bindings to minifiers exist in almost all programming languages. Some implementations are merely using several regular expressions to trim whitespace and comments. -

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.
