Existing CS Parsers

Jump to bottom
Andre Lewis edited this page Sep 10, 2016 · 12 revisions

Coffeescript has been through many iterations and forks, many to add functionality to the original language and sometimes to fix ambiguities and outstanding issues.

In addition the original parser has become convoluted and is harder to add more features to. As a result there are a lot of variants of the original parser at many levels of completeness and support for recent changes in the ES2015+ ecosystem.

This page is the beginning of a eventually comprehensive list of parsers. The goal is to understand where future efforts should focus and to assess the amount of work necessary to bring CS6 to parity with the core features of ES6+.

Parsers:

  • jashkenas/coffeescript (github) - The Original
  • icedcoffee (website) - Async/Await oriented
  • coffeescript redux (CS2) (github) - An attempt to rewrite from scratch
  • coco (github) - Based on the original parser
  • Others? Please add variations here.

and for completeness:

  • Decaffeinate (github) - Convert Coffeescript into Javascript
