newpeg

Parser generator for JavaScript.

• Based on PEG.js syntax.
• Slow.
• Small footprint of generated parser.

Planned

There's a set of tasks which would be nice to try in Web.

• CodeMirror-based three-way editor for grammars that shows location of parser errors and allows to debug parsers.
• Iterative parsers for colorers and live code editors showing translated output.
• Streamable parsers for large files.
• Yet another typed JavaScript.

None of the parser generators I've seen allows it from the box, and none has good enough source code documentation to base the work on it.
