Readme

ast-parents Flattr this!experimental #
Walks a JavaScript AST, such as one supplied via esprima, and adds a parent property to each node.
Makes it much easier to navigate the AST, and the parent properties added here are non-enumerable so you can still serialize the tree to JSON without JSON.stringify throwing an error.

Usage ##

ast-parents
require('ast-parents')(ast)
Where ast is an AST object. For example:
var esprima = require('esprima')
var fs = require('fs')

var src = fs.readFileSync(__filename, 'utf8')
var ast = esprima.parse(src)

parents(ast)

ast.body[0].parent === ast.body
