grab the output of command complete (C-D)

[Renato Fabbri]

I am almost sure I was able to do this...

Example:

:colo <C-D>

shows the available colorschemes.

If I want to have them in a variable,

redir @a

colo ^D
redir END

does not work, in any variation of colo ^D I tried

(exe 'colo ^D', exe 'colo <C-D>', etc).

Help?

Newer Vims (7.4.2011 or newer):
:echo getcompletion('', 'color')
=> ['blue', 'darkblue', 'default', 'delek', 'desert', ...]


Older Vims:
:echo ComplList('colo ')

func! ComplList(str)
" {str} partial command-line
let expansion = GetComplAll(a:str)
if a:str =~ '\s'
return split(strpart(expansion, matchend(a:str, '^.*\s')))
else
return split(expansion)
endif
endfunc

func! GetComplAll(str)
" {str} partial command-line
let d = {}
exec "sil norm! :". a:str. "\<C-A>\<C-\>e(extend(d,{'cmdl':getcmdline()}).cmdl)\n"
return get(d, 'cmdl', '')
endfunc
