Emacs：当前源缓冲区中的函数列表

Question

SublimeText2 has a command Command+R (on the mac) that shows a list of functions in the current buffer. For example, i'm editing C code, then command+R opens a hovering window with the list of functions in the current source.

Does have emacs have something similar. I know it can be coded, but has it?

I guess one could use clang to output the function definitions and their line numbers, put this in new buffer with links to the original source.

But how?

Answer 1

It's imenu . Use imenu-add-menubar-index and then in the menu is a list of functions. Works for c-mode . Let's see if it works for R mode ...

Answer 2

You can use imenu as mentioned by Sapsi I like to use it with one of the completition libraries, for example with ido: https://gist.github.com/magnars/2360578 or with helm with helm-imenu
