decaffeinate-parser 

This project uses the official CoffeeScript
parser to parse CoffeeScript source
code, then maps the AST generated by the parser to one more suitable for the
decaffeinate project based on
the AST generated by
CoffeeScriptRedux.

This project might be useful to anyone who wants to work with a CoffeeScript
AST and prefers the AST generated by CoffeeScriptRedux, but wants to avoid the
source compatibility issues introduced by using that project. Note that it is
not 100% compatible with CoffeeScriptRedux:

* Single-line functions, if statements, etc. have blocks for bodies.
* String interpolation nodes are modeled after TemplateLiteral from ES6 rather
than being a series of nested ConcatOp nodes.
* Triple-quoted strings have the node type Herestring rather than String.
* Virtual nodes (such as the LogicalNotOp generated by an unless) are
marked as such with a virtual: true property.
* do is handled with the DoOp node type.
* for-in loops do not have an implicit step property.
* Ranges of programs with indented blocks are correct.
* super is supported in classes.
* extends is usable as a binary operator and in class declarations.
* // (floor division) is supported.

Install

Usage

This example gets the names of the parameters in the add function:

`js
import { parse } from 'decaffeinate-parser';
const program = parse('add = (a, b) -> a + b');
const assignment = program.body.statements[0];
const fn = assignment.expression;
console.log(fn.parameters.map(param => param.data)); // [ 'a', 'b' ]
