debug.js

require.registerExtension('.js', function(js){
  return js.replace(/^ *\/\/debug: */gm, '');
});

some-file.js

if (options.debug) require('./debug');

while (iAmParsingStuff) {
  //debug: console.log('state -> %s', this.state)
}

sweeeeeeet

Haha, nice. This could be a feature supported by node.

yeah that would be cool, just require('debug') to enable. Highly doubt anything like it would ever get in haha, but its a nice alternative to having actual conditionals scattered throughout your lib slowing it down

Did you happen to test how much slower? Just curious.

nah, it only has an effect when required so it doesnt really matter, and it would only affect the initial boot

oh, you meant the extra function calls? it depends. writing a streaming parser an extra function call or two could add up quite a bit if you parse 50kb, that could be 50k calls that you dont want :)
