astw

walk the ast

NB: This is a fork of substack's astw module modified to allow passing of esprima parse options. All credit for the module goes to substack.

example

var astw = require('astw-opts');
var deparse = require('escodegen').generate;
var walk = astw('4 + beep(5 * 2)', { loc: true,  });

walk(function (node) {
    var src = deparse(node);
    console.log(node.type + ' :: ' + JSON.stringify(src));
});

methods

var astw = require('astw')

var walk = astw(src[, opts])

Return a walk() function from the source string or ast object src with optional parse config options for esprima.

walk(cb)

Walk the nodes in the ast with cb(node) where node is each element in the ast from esprima but with an additional .parent reference to the parent node.

install

With npm do:

npm install astw-opts
