I have git and git-flow installed via Homebrew. I am on a Mac.

I have zsh 5.0.2 (x86_64-apple-darwin12.4.0)

git completions are working. git-flow completions are not.

I cannot get git flow completions to work.

I've tried two ways to install the functions.

Method 1

I installed git-flow using Homebrew, which added the functions to this directory /usr/local/share/zsh/site-functions

That path is in my $fpath

> echo $fpath
/usr/local/share/zsh/site-functions /usr/local/Cellar/zsh/5.0.2/share/zsh/functions

Method 2

I downloaded the git-flow completion functions from https://github.com/zsh-users/zsh-completions and put the file in ~/.zsh/completions.

I then added the directory to my ~/.zshrc

fpath=(~/.zsh/completions $fpath)

> echo $fpath
/Users/jord/.zsh/completions /usr/local/share/zsh/site-functions /usr/local/Cellar/zsh/5.0.2/share/zsh/functions

Neither of these methods works.

What am I doing wrong?

UPDATE

The output of git-flow [CTRL+X] [h] is:

> git flow
tags in context :completion::complete:git::
    all-files  (_files _default _git (eval))

UPDATE 2

It's working!

I put the _git functions from the URL provided by @mpy in ~/.zsh/completions/ and added ~/.zsh/completions to my $fpath in ~/.zshrc.

fpath=(
  ~/.zsh/completions
  $fpath
)

I then downloaded git-flow-completion.zsh from https://github.com/bobthecow/git-flow-completion and put it into ~/.zsh/completions and sourced that file from my .zshrc.

git and git flow completions are now working, but I have no idea why?!

Both methods should be fine. As it is working here and just to make sure: Did you start a new zsh instance after putting the file into $fpath? And, can you please post the output of git-flow [CTRL+X] [h]? –  mpy Jul 24 '13 at 22:27
    
I've updated my post with the output. I assume this means it can't find the git-flow completions, only the git completions? –  jordelver Jul 25 '13 at 8:50

I wrote an answer, although I don't have a solution. But perhaps one of my ideas for troubleshooting will help -- and I couldn't fit everything into a comment ';)' –  mpy Jul 25 '13 at 11:35

The file $fpath/_git-flow provides completion for git-flow (with dash), see its first line:

#compdef git-flow

So, using git-flow [CTRL+X] [h] I get

$ git-flow [CTRL+X] [h]
tags in context :completion::complete:git-flow::
    argument-1  (_arguments _git-flow)
tags in context :completion::complete:git-flow:argument-1:
    commands  (_describe _git-flow)

showing that zsh detects that the prompt is now at the first argument to git-flow.

The completion function for git is very powerful (and to be honest, I cannot ,,read'' it through), so also git flow (w/o dash) provides the git-flow completion, but the context is different:

$ git flow [CTRL+X] [h]
tags in context :completion::complete:git::
    argument-rest  (_arguments _git)
tags in context :completion::complete:git-flow::
    argument-1  (_arguments _git-flow _call_function _git)
tags in context :completion::complete:git-flow:argument-1:
    commands  (_describe _git-flow _call_function _git)

If using a non existent git module, I end up with

$ git foo [CTRL+X] [h]
tags in context :completion::complete:git::
    argument-rest  (_arguments _git)
tags in context :completion::complete:git-foo::
    directories    (_files _git) 
    globbed-files  (_files _git) 
    all-files      (_files _git)

which looks closest to your result.

Therefore my suggestions would be:

  • check your _git-flow completions file isn't corrupted and has the right line endings (EOL)
  • trigger completion for git-flow with e.g. git-flow [CTRL+X] [h] and have a look at the output of which _git-flow:

    • if the completion function cannot be read this results in

      $ which _git-flow
      _git-flow () {
              # undefined
              builtin autoload -XUz
      }
      
    • if read correctly you get the function printed:

      $ which _git-flow
      _git-flow () {
          local curcontext="$curcontext" state line
          typeset -A opt_args
          _arguments -C ':command:->command' '*::options:->options'
          ...
      
  • try to compile the _git-flow function file with zcompile _git-flow to see if there will be an error. (Then the resulting file _git-flow.zwc should be read upon autoloading.)

  • examine ~/.zcompdump if the _git-flow completion is listed.

Thanks for the useful answer. If I compile the function file with zcompile the completions show up, but only for git-flow not git flow. Why is it necessary to compile the functions? And how can I get it working for git flow? –  jordelver Jul 25 '13 at 12:53

@jordelver: Frankly, I don't know, why it's working when compiled. That shouldn't matter. Do you have the up-to-date version of the _git completion? If there is a older version of _git somewhere in your $fpath things might get screwed up. Try to compile _git as well?! –  mpy Jul 25 '13 at 14:39
    
If I have two versions of the functions which take precedence? I have a _git file in /usr/local/share/zsh/site-functions AND in /usr/local/Cellar/zsh/5.0.2/share/zsh/functions. Once is the default zsh install, one is installed by the git Homebrew package :| And, they are different, one seems to be zsh script only and the other uses the bash completions :/ –  jordelver Jul 25 '13 at 15:12

@jordelver: I don't know what happens with two identical named files, but it sounds like a source of irritations. Try to move both files out of $fpath and put only the official _git function from sourceforge.net/p/zsh/code/ci/master/tree/Completion/Unix/… into $fpath. –  mpy Jul 25 '13 at 15:21
    
Ok, it's working! But I don't have any idea why ;) See my update at the top. I don't understand why I have source files when there seems to be an _ convention, but anyway, it's working. Thank you very much for your help :) –  jordelver Jul 25 '13 at 16:59
