Hi, list.
I wrote a patch to add new function 'capture()'.
When you want to get a list of all commands/functions/mappings with using vim
script, probably, you'll do like follow.
---------------------------------
let funcs = ''
redir => funcs
silent! function
redir END
---------------------------------
I guess, most of vim script programmers want to get the result as expression.
not command, want to get more easily.
If vim have 'capture()' which allow to getting those command line 'function', I
guess this is very useful.
For example, getting :Command list as array.
---------------------------------
:echo map(split(capture("command"), "\n")[1:], 'split(v:val[4:])[0]')
---------------------------------
One more thing. vim doesn't support nest of :redir.
---------------------------------
function! s:foo()
let a = ''
redir => a
silent echo "foo"
redir END
return a
endfunction
function! s:bar()
let a = ''
redir => a
call s:foo()
redir END
return a
endfunction
echo s:bar()
---------------------------------
This 'echo s:bar()' doesn't show anything. But capture() can do it.
---------------------------------
echo capture("s:bar()")
foo
---------------------------------
capture() is working on sandbox. so you can't use this in modeline.
Below is a patch. How about this new feature?
