Vim Ctrl+g = see current function name

Question

You know how we can get information about the current file with Ctrl+g. I would like to extend that to show the current function name the cursor is currently in. Assume C language.

Any Vim pros out there to help me out?

Answer 1

You must really have large functions.

I see two ways to do that:

1. by folding with the cursor on a blank line, it will fold the entire current function, letting you see its name. za to fold, look at the name, za to unfold.

2. by using either TagList or TagBar, invoking either of these plugins will create a split window with an outline of your file and the cursor positioned on the current function's name and the name highlighted. If your cursor is on a member's name it will show the member instead so you may have to move your cursor over a keyword like int or on some whitespace.
