list all functions defined in a file

Question

When editing a python file in vim;

What is a good way to get all functions or classes listed plus the opportunity to jump to the lines where they are defined?

Answer 1

A little "manual" but:

:g/def\ .*

will show you the lines and, in normal mode, you can press <line number>gg to jump to that line.

Building on jan's self found answer below:

A user command GJ (for GrepJump!)

command! -nargs=1 GJ vimgrep <q-args> % | copen

Answer 2

TagList or Tagbar plugin. You will need to have ctags, or exuberant ctags installed.

Excerpt from my .vimrc:

Bundle "majutsushi/tagbar"
  nmap <script> <silent> <unique> <F4> :TagbarToggle<CR>

Answer 3

Got it. If you use the :vim command, your search is redirected to the quickfixlist. Thus,

:vim /def\ ./ %
:copen

i.e. "do a vim[grep] in the current file" and "open the quickfix window" to jump to the matches will do the task.

Answer 4

Assuming you use ctags or some variant the default :tag foo<Tab> or :tag <Tab> command could be enough but you may get tags from other files:

:ilist def .* is another solution. At the prompt, type :<Number><CR>:

But I love CtrlP's :CtrlPBufTag:
