Futago-za Ryuu fbc8ea2bdf Add an ignore file
The gulp file is usuaully used to glob the JavaScript files and run ESLint on them, but editor based instances of ESLint (e.g. VSCode extension) don't read the gulp file, so can't tell which files to ignore unless specified in the official .eslintignore file.

PEG.js 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.

PEG.js is still very much work in progress. There are no compatibility guarantees until version 1.0


  • 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
