i found your website searching for a solution for the exact same problem like udo. is it possible to get in contact with him? i would like to know, if he implemented such thing using a regexp parser or if he found an other solution.

hope you’ll find some time for releasing / open-sourcing your parser, tim :)

Looking at what you want to do with it, I’m not sure you need a full parser. I think your requirement could be achieved with a simpler method. Perhaps just running a single RegExp over the whole thing. The following pattern should match the gettext call assuming a double-quoted string literal is the first argument. have a go!

<?php
$input = '// example js source
somediv.innerHTML = gettext("Please login first");
anotherdiv.innerHTML = gettext ( "And another", junk );';

preg_match_all('/gettext\s*\(\s*"((?:\\\\.|[^\r\n"\\\\])*)"/', $input, $matches );
var_dump( $matches[1] );

I would probably need only a subset of the functions of your compiler. In fact I only need to know which functions in a .js file are being called and which (constant) parameters are passed to them.

Something like:

somediv.innerHTML = gettext(”Please login first”);

The text “Please login first” is what I need.

Any chance to get your source? I can’t seem to find any other JS parser in PHP…
