Vim JSDoc, PHPDoc, JavaDoc, RDoc info

Here is the deal,

If you've used Aptana, Eclipse or even Microsoft Expression Web editor, then you've seen that they feature a Balloon Text or Intellisense popup showing hints/info of built-in and custom objects, methods, etc.

They get the info thru JSDoc, PHPDoc, JavaDoc, RDoc, etc.

I'd like to get these feature in Vim, maybe impleme开发者_如何学JAVAnted as omnicompletion and also since Mac/GVim supports balloon text, as this as well.

This feature actually exists and is defined in each file type's Omni-completion. For example, enabling PHP's omni-completion will show completions in a popup window as well as the method definition in a smaller buffer which opens at the top of the current tab-frame.

Activate it by adding the following to your .vimrc

filetype plugin on
au FileType php set omnifunc=phpcomplete#CompletePHP

And then using C-x C-o for completion. (I find many people like to remap this to C-space to mimic Visual Studio)
