Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. General enough to parse any programming language. Fast enough to parse on every keystroke in a text editor. Robust enough to provide useful results even in the presence of syntax errors.

ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees. It’s widely used in academia and industry to build all sorts of languages, tools, and frameworks. Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for...

Optimize JS is an experimental JavaScript transformation tool created to reduce initial parsing and execution time in older browser engines. It parses JavaScript into a syntax tree and identifies functions that are immediately invoked or likely to execute eagerly. Those functions are wrapped in parentheses so engines such as older V8 versions can avoid unnecessary lazy preparsing. The tool can operate from the command line or through a JavaScript API and can optionally generate source maps. ...
