Show function name in status line

by

To show current function name in C programs add following in your vimrc:

fun! ShowFuncName()
  let lnum = line(".")
  let col = col(".")
  echohl ModeMsg
  echo getline(search("^[^ \t#/]\\{2}.*[^:]\s*$", 'bW'))
  echohl None
  call search("\\%" . lnum . "l" . "\\%" . col . "c")
endfun
map f :call ShowFuncName() <CR>

Or if you need the “f” key, just map the function to whatever you like.
