CoffeeScript Family (& Friends)

Family (share genes with CoffeeScript)
  • Coco A CoffeeScript dialect that aims to be more radical and practical, also acts as a test bed for features that get imported in CoffeeScript.
    • LiveScript is a fork of Coco that is much more compatible with CoffeeScript, more functional, and with more features.
  • IcedCoffeeScript A CoffeeScript dialect that adds support for await and defer keywords which simplify async control flow.
  • Parsec CoffeeScript CS based on parser combinators. The project's aim is to add static metaprogramming (i.e. macros + syntax extensibility) to Coffee Script (CS), similar to how Metalua adds such features to Lua. The resulting compiler, once merged with the official compiler, should be usable as a drop-in replacement for it.
  • Contracts.coffee A dialect of CoffeeScript that adds built-in support for contracts.
  • Uberscript, a CoffeeScript fork that adds type annotations which are compiled to Google closure compiler type annotation comments.
  • ToffeeScript A dialect of CoffeeScript that support Asynchronous Syntax and Regexp operator =~
  • Caffeine A dialect of CoffeeScript that support packages and classes import, useful for browser applications
  • heap.coffee A dialect of CoffeeScript that offers a C-like type system with manual memory management
  • EmberScript Ember.js-infused CoffeeScript.

  • LispyScript A JavaScript with Lispy syntax and Macros. ○
  • wisp A homoiconic JavaScript dialect with Clojure syntax, S-expressions and macros. Aims to be rich subset of Clojure(Script) that seamlessly interops with both Clojure(Script) and JavaScript. ○
  • Hot Cocoa Lisp A Lisp-like language that compiles to JavaScript. ○
  • Sibilant JavaScript with a lisp. ○
  • ki Clojure-like syntax, mori's immutable data structures in a few sweet.js macros. Can be intermixed with JavaScript. ○
  • jisp A JS-native and axiomatic Lisp that focuses on the core ideas of code-as-data, S-expressions, and macros, introducing as few new concepts as possible. ○
