Autocomplete Class methods in textmate?

When I define a class "Bla" with the method "foo" in a file and t开发者_运维问答han create a new file and write in textmate "Bla.f" is there a way to autocomplete the missing "oo"?

I only found the ESC key but it doesn't work for this.

TextMate autocomplete only works with words you have already typed out in the same file. If you really need this functionality, I would check out some other editors. My personal favorite is VIM. In a way, it gives you the best of both worlds. It's very lightweight and has autocomplete across files. This means if you have a class Bla open in one tab, you can do autocomplete with it elsewhere in your application. If you're really looking for true class autocompletion, you'll need a full IDE like NetBeans or RubyMine.
