How to enable git file tab completion with zsh compinit?

问题

I have a problem with the zsh tab completion: After running:

autoload -U compinit
compinit

Git tab completion for files does not work any more. For example if I type git add my_f to complete my_file, nothing happens. The zsh git completion only seems to work for git branches and tags.

Without the compinit stuff, git file completion works, but of course I'm missing out all the fancy branch completion stuff.

So... Is there a way to make git file completion AND git branch completion possible at the same time in zsh? This would really help me a lot.

(I'm adding an answer here mostly to get it off the unanswered list.)

As you can see from the comments, it does work. I believe the whole zsh situation has recently improved significantly, too:

completion: make compatible with zsh

Modify git-completion.bash so that it also works with zsh when using bashcompinit. ...

So, if you happen across this googling, and your completion isn't working, try upgrading your git-completion.bash (link points to the blob from git.git HEAD). Current git version is 1.7.3.2; it should make it into the next one.

Note that, with Git 2.30 (Q1 2021), the instructions for command line completion (in contrib/) for zsh have been updated.

See commit 3ebd945 (02 Jul 2020) by Alexey (ogonkov).

completion: fix zsh installation instructions

Fix wrong script in completion configuration. zsh wants bash completion path here, not path to itself.

Add compinit autoload command, since whole thing didn't work if it is not loaded.

So the command would be:

# The recommended way to install this script is to make a copy of it in
# ~/.zsh/ directory as ~/.zsh/git-completion.zsh and then add the following
# to your ~/.zshrc file:
#
#  fpath=(~/.zsh $fpath)
#  autoload -Uz compinit && compinit

Warning: With Git 2.30 (Q1 2021), Zsh autocompletion (in contrib/) has been patched, as mentioned in here by its author "Felipe Contreras".

completion: bash: remove zsh wrapper

^{Signed-off-by: Felipe Contreras}

It has been deprecated for more than eight years now, it's never up to date, and it's a hassle to maintain.

It's time to move on.

With Git 2.30 (Q1 2021), there is a hotfix for a recent breakage.

completion: bash: fix gitk alias regression

Long time ago when the _git_complete helper was introduced, _gitk was replaced with __gitk_main, and a placeholder for backwards compatibility pointing to __git_wrap_main_gitk was left in place.

When "__git_complete gitk __gitk_main" was called, that created the __git_wrap__gitk_main helper, which is just basically "__git_func_wrap __gitk_main" plus complete options.

Unfortunately the commit b0a4b2d257 ("completion: add support for backwards compatibility", 2012-05-19, Git v1.7.11-rc0 -- merge) missed a previous instance of a call to _gitk in _git_gitk

So, basically we had __git_wrap__git_main -> __git_func_wrap __git_main -> __git_complete_command gitk -> _git_gitk -> _gitk -> __git_wrap__gitk_main -> __git_func_wrap __gitk_main -> __gitk_main.

There was never any need to call __git_func_wrap twice. Since _git_gitk is always called inside the wrapper, it can call __gitk_main directly.

And then, in commit 441ecdab37 ("completion: bash: remove old compat wrappers", 2020-10-27, Git v2.30.0 -- merge listed in batch #4) _gitk was removed, which triggers the following error:
_git_gitk:9: command not found: _gitk  
Let's call the correct function: __gitk_main.
