History

Futago-za Ryuu 95abd42c95 Ensure VERSION is consistent The PEG.js version is exported and also written into the generated parser. In both these instances the version is a separate string, which means every time the version is bumped, it has to be changed in 3 places. This commit makes it slightly less of a maintenance burden.		6 years ago

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
