Each time the regex that i'm using to strip console.log|error|etc calls from my source breaks a build, I try and find out how people do this 'properly'. I have yet to find anything other than a regex out there, so this time instead of patching my inevitably flawed expression I wrote something based on a JavaScript lexer (
https://bitbucket.org/ned/jslex). It's no great work of computer science but I think some people will find it useful so I thought i'd make it my first open source project.
