Highlighting function calls in textmate

It feels like I'm missing something really simple here. I've been using Coda for a while now and I'm now playing around with Textmate. I'm unable to find a way to syntax highlight function calls in Textmate. I've poked around the documentation but ca开发者_JAVA技巧n't believe I'd have to dig deep into Textmate and mess around with regex to make this work.

Function calls are inheriting the foreground color. This is javascript but I get the same in PHP.

In Textmate, syntax coloring is entirely controlled by the language definition in the "bundle" of the relevant language. Both the PHP (HTML) and Javascript bundles give function definitions special treatment, but neither highlights function calls.

So yes, if you want to change this, you'll need to use the Bundle Editor and learn to edit the regex-based language definition (marked with an L icon in the bundle).
