Roadmap

Roadmap

The current goal is to get to 1.0.0 as fast as possible. This mostly means polishing, cleaning up the code, rewriting the documentation, and improving performance. The matter is complicated by the fact that the JavaScript ecosystem is moving fast, resulting in a need to modernize PEG.js code and infrastructure in few areas (e.g. ES6, linting, build system, tests).

0.10.0 (“Polish”)

Goal: Polish things to the 1.0.0 level (modulo performance and documentation).

• AMD support (#362)
• Error reporting improvements
  • Report duplicate rules as errors (#318)
  • Report duplicate labels as errors (#270)
  • Improve error messages (#371)
  • Fix nonsensical syntactic predicate messages (#194)
  • Rethink quoting in user-facing messages (#127)
• Make &... and !... not return any value (#66)
• Small CLI improvements (#370)
