Use helper functions for git completion in my own completions

Use helper functions for git completion in my own completions

[Ansgar Burchardt]

Hi,

is it possible to use the helper functions defined in "_git" for the git
command in my own completion functions?

I am taking my first steps with writing completions for the
git-import-dsc, git-import-orig commands in Debian, but am not surehow I
can make sure helper functions such as __git_branch_names are available
when I user "git-import-dsc" (they are available when I use "git
import-dsc").

Regards,
Ansgar

May be _dispatch could do it ?

It seems to work if you modify $words in _git-import-dsc, call _git
and rely on it calling you back. As follows:

#compdef git-import-dsc
if [[ $words[1] = git-* ]]; then
  words=( ${=words[1]/-/ } ${words[2,-1]} )
  _git "$@"
  return
fi

The rest of your function can then follow on here and everything in _git
should be defined.

Yes, though with the recent(-ish) rewrite (and in general), I'm not sure 
there's really a stable API.

E.g. if __git_pattern_escape isn't needed by _git anymore, I suspect it 
would simply disappear.  As would __git_commits2, or whatnot.

If you create the _git-{command-name} function (e.g. _git-import-dsc), 
it will be used by _git (at least by the version of _git I'm currently 
using).  By virtue of being used from within _git, all of the helper 
functions will exist, because they're defined when _git is autoloaded.

Yes.  The helpers are still in need of a clean-up.  I have a rather
sizable todo-list still, but preciously little time.
