Parser for Rust source code
Parser for Rust source code
Parser for Rust source code is a major Rust crate for parsing Rust source code (token streams) into a syntax tree (AST) that procedural macros can inspect or transform. The primary target is macro authors: you can parse TokenStreams into syn::File, syn::Item, syn::Expr, syn::Type, etc. It offers rich data structures, fine-grained parsing, span tracking (for error reporting), traversal and mutation APIs (visit, fold, visit_mut), printing back to tokens, and strong feature-gating so you only compile what you need. ... -

goquery
A little like that j-thing, only in Go
goquery brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/HTML package and the CSS Selector library Cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), and detach()) have been left off. Also, because the net/HTML parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. ... -

JavaParser
Java 1-17 Parser and Abstract Syntax Tree for Java
...If you are not familiar with them we suggest taking a look at the maven quickstart projects. Since Version 3.5.10, the JavaParser project includes the JavaSymbolSolver. While JavaParser generates an Abstract Syntax Tree, JavaSymbolSolver analyzes that AST and is able to find the relation between an element and its declaration (e.g. for a variable name it could be a parameter of a method, providing information about its type, position in the AST, etc). When choosing open source technologies it is important to know your choice will be rewarded by continuous support. ... -

PHP Parser
A PHP parser written in PHP
...A parser is useful for static analysis, manipulation of code and basically any other application dealing with code programmatically. A parser constructs an Abstract Syntax Tree (AST) of the code and thus allows dealing with it in an abstract and robust way. As the parser is based on the tokens returned by token_get_all (which is only able to lex the PHP version it runs on), additionally a wrapper for emulating tokens from newer versions is provided. This allows to parse PHP 7.4 source code running on PHP 7.0, for example. ... -

PostCSS
A tool for transforming CSS with JavaScript
PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. ... -
