• some plugins: ie UltiSnips

Problem

when typing a :call command, where I'd like to invoke some routine of a plugin directely, cmdline completion (with TAB key, by default) stops after the # .

ie: I want to complete :call UltiSnips#ListSnippets()
where many other UltiSnips routines are available.

• When typing :call ult and press TAB , I get:
  :call UltiSnips# with a listing of all possible matches.

  1. When I press TAB further, it toggles through all matches correctely

  2. BUT if I try to contiue typing the function name like :call UltiSnips#List and hit TAB , it wont complete the funtion's name, but ANY completion, that is starting with List (what I typed after the # ; ListTemplateSuffixes( in my case)

Answer 1

This has been fixed by recent Vim patch 7.4.516: issue 253: completing function name with a # does not work .

So, you just need to update your Vim (by compiling it yourself; or just wait until your distribution provides such upgrade).
