falafel-helpers

falafel-helpers
===============

Wraps your falafel callback function, adding handy helpers:

``js
var falafelHelpers = require('falafel-helpers');

var src = falafel(fs.readFileSync('test.js', 'utf8'), helpers.wrap(function (node) {
if (/Expression$/.test(node.type)) {
node.wrap('debug(', ')');
} else if (node.type === 'BlockStatement') {
node.before('console.log("entering block");');
node.after('console.log("exiting block");', true); // second argument makes it use a try-finally to always execute the inserted code
}
});
`

Also works with falafel-map:

`js
var falafelHelpers = require('falafel-helpers');

var src = falafel(fs.readFileSync('test.js', 'utf8'), helpers.wrap(function (node) {
if (/Expression$/.test(node.type)) {
node.wrap('debug(', ')');
}
}, { falafelMap: true }));
