node-edit/example/index.js

Launch $EDITOR with a default set of text and allow the user to make changes. Strip out the comments and fire a callback with the new text, or false if the text has not changed.

var edit = require('../edit.js');

edit("# This is an example\n# Comments will be ignored\n# Try adding some more text to this file", function(text) {
  console.log(text);
});
