I'm trying to achieve something simple, usually called "function hints". For example, scintilla-based editors have it:

enter image description here

You type a name, and just get the prototype. There are a few problems with that in vim:

  • You have to rebuild the ctags to keep it up to date
  • You can't type C-X C-O after the (, you'll just get "Pattern not found"
  • You can't type C-X C-O in normal mode, the cursor will just jump around
  • You get the annoying preview window at the top

I've tried a few plugins; most of them mess things up even more [^1].Can anyone recommend a simple way to get just that ? A simple rectangle containing the function prototype and nothing more.

[^1] It's really mind-numbing how idiotic some of these plugins are. One plugin (I won't mention it) actually contained in the .vim file a list of functions from libc.
