Peggy
Peggy is a simple parser generator for JavaScript that produces fast parsers with excellent error reporting. You can use it to process complex data or computer languages and build transformers, interpreters, compilers and other tools easily.
Peggy is the successor of PEG.js.
Migrating from PEG.js
Peggy version 1.x.x is API compatible with the most recent PEG.js release. Follow these steps to upgrade:
- Uninstall
pegjs(and@types/pegjsif you're using the DefinitelyTyped type definitions - we now include type definitions as part of peggy itself). - Replace all
require("pegjs")orimport ... from "pegjs"withrequire("peggy")orimport ... from "peggy"as appropriate. - Any scripts that use the
pegjscli should now usepeggyinstead. - That's it!
Features
- Simple and expressive grammar syntax
- Integrates both lexical and syntactical analysis
- Parsers have excellent error reporting out of the box
- Based on parsing expression grammar formalism — more powerful than traditional LL(k) and LR(k) parsers
- Usable from your browser, from the command line, or via JavaScript API
- Source map support
Getting Started
Online version is the easiest way to generate a parser. Just enter your grammar, try parsing few inputs, and download generated parser code.
Documentation
Full documentation is available at peggyjs.org.
