astw
walk the ast
This module is a faster version of
falafel
that only does ast walking and .parent
tracking, not source transforms.
example
var astw = require('astw');
var deparse = require('escodegen').generate;
var walk = astw('4 + beep(5 * 2)');
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
.
Optionally:
opts.ecmaVersion

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.
