postcss - Transforming styles with JS plugins
PostCSS is a tool for transforming styles with JS plugins. These plugins can lint your CSS, support variables and mixins, transpile future CSS syntax, inline images, and more.PostCSS is used by industry leaders including Wikipedia, Twitter, Alibaba, and JetBrains. The Autoprefixer PostCSS plugin is one of the most popular CSS processors.

In less poetic terms, Recast exposes two essential interfaces, one for parsing JavaScript code (require("recast").parse) and the other for reprinting modified syntax trees (require("recast").print). See ast-types (especially the def/core.js) module for a thorough overview of the ast api.

If you want to use from the browser go to the releases page on GitHub and download the version you want (minified or not). We only officially support node >= 0.10 as the libraries we use for building and testing don't work on older versions of node. That said since this module is so simple and doesn't use any parts of the node API if you use the pre-built version and find a bug let us know and we'll try and fix it.

This is a PHP 5.2 to PHP 7.2 parser written in PHP. Its purpose is to simplify static code analysis and manipulation. Documentation for version 4.x (stable; for running on PHP >= 7.0; for parsing PHP 5.2 to PHP 7.2).

Esprima (esprima.org, BSD license) is a high performance, standard-compliant ECMAScript parser written in ECMAScript (also popularly known as JavaScript). Esprima is created and maintained by Ariya Hidayat, with the help of many contributors. Esprima can be used to perform lexical analysis (tokenization) or syntactic analysis (parsing) of a JavaScript program.

⚡️ Walt is an alternative syntax for WebAssembly text format. It's an experiment for using JavaScript syntax to write to as 'close to the metal' as possible. It's JavaScript with rules. .walt files compile directly to WebAssembly binary format. 🚀 Try it out in the Walt Explorer.

Why? While I've been working on Under-the-hood-ReactJS I spent enormous amount of time on creating schemes. Each change in code or flowchart affects all entire scheme instantly, forcing you to move and align 'broken pieces'. Just repeated manual work... Imagine a library which takes any JS code and generate SVG flowchart from it, works on client and server. Allows you easily adjust styles scheme for your context or demonstrate your code logic from different abstractions levels. Highlighting, destructing whole blocks, custom modifiers for your needs etc.

gitbase, is a SQL database interface to Git repositories. It can be used to perform SQL queries about the Git history and about the Universal AST of the code itself. gitbase is being built to work on top of any number of git repositories.

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary. Prettier can be run in your editor on-save, in a pre-commit hook, or in CI environments to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!

Check out a small demo here and see the component in action highlighting the generated test code here. There are other syntax highlighters for React out there so why use this one? The biggest reason is that all the others rely on triggering calls in componentDidMount and componentDidUpdate to highlight the code block and then insert it in the render function using dangerouslySetInnerHTML or just manually altering the DOM with native javascript. This utilizes a syntax tree to dynamically build the virtual dom which allows for updating only the changing DOM instead of completely overwriting it on any change, and because of this it is also using more idiomatic React and allows the use of pure function components brought into React as of 0.14.

Once upon a time, an unsuspecting Mozilla engineer created an API in Firefox that exposed the SpiderMonkey engine's JavaScript parser as a JavaScript API. Said engineer documented the format it produced, and this format caught on as a lingua franca for tools that manipulate JavaScript source code. Meanwhile JavaScript is evolving, notably with the upcoming release of ES2015. This site will serve as a community standard for people involved in building and using these tools to help evolve this format to keep up with the evolution of the JavaScript language.

Espree started out as a fork of Esprima v1.2.2, the last stable published released of Esprima before work on ECMAScript 6 began. Espree is now built on top of Acorn, which has a modular architecture that allows extension of core functionality. The goal of Espree is to produce output that is similar to Esprima with a similar API so that it can be used in place of Esprima. The primary goal is to produce the exact same AST structure and tokens as Esprima, and that takes precedence over anything else. (The AST structure being the ESTree API with JSX extensions.) Separate from that, Espree may deviate from what Esprima outputs in terms of where and how comments are attached, as well as what additional information is available on AST nodes. That is to say, Espree may add more things to the AST nodes than Esprima does but the overall AST structure produced will be the same.
