Question

Is it possible for Emacs to provide a short list of possible function arguments whenever you are about to call a function?

For example, if I type out this:

Foo(

I would like to see something like

Foo(int x)
Foo(std::string x)
Foo(int x, int y, int z = 5)

pop out under my Foo(

Currently I am using Emacs for C++ work, but would like to know about such features for other languages like the Lisps, Python, etc., as well. Also, I am not sure what this kind of feature is called, so I would appreciate it if you could tell me that too.

The term "intellisense" comes to mind, though I believe that's a Microsoftism. http://stackoverflow.com/questions/2582360/emacs-intellisense has some information that might be helpful. — FatalError, Jan 28 '12 at 04:02
actually the feature you are asking for called Eldoc in Emacs. IIRC it supports lisp and python2 not sure about other languages — kindahero, Jan 28 '12 at 06:56
check out [ropemacs](http://stackoverflow.com/questions/2855378/ropemacs-usage-tutorial) for python — Tom, Jan 28 '12 at 08:44

Take a look at GCCSense. It's a tool from the author of auto-complete-mode and it uses gcc to find candidates for code completion as the name suggests. CEDET also provides a smart completion mechanism for C/C++ (and other languages). This article on setting up CEDET might be useful to you as well.
