Latest commit broke plugin

[lukasmalkmus]

Hi, your latest commit broke z for me.
fish 2.6.0
bash 4.4.12
z 1.9
I installed z (this plugin) with omf.

Running z in fish returns:

bash: line 2: _z: command not found
cd: The directory 'bash: line 1: /Users/lukasmalkmus/.local/share/omf/pkg/z/functions/../z/z.sh: No such file or directory' does not exist

Runningcd returns:

bash: line 2: _z: command not found
cd: The directory 'bash: line 1: /Users/lukasmalkmus/.local/share/omf/pkg/z/functions/../z/z.sh: No such file or directory' does not exist

What version of OMF do you have? (omf --version)?

Latest commit refactored the plugin to bundle z with the plugin. It uses git submodules, so I'm thinking that the submodule did not get cloned for some reason. Older versions of OMF would not have done that step also.

Oh My Fish version 5

I just tried a fresh install in an empty environment and it worked for me. So there must be some condition causing this problem.

The following should fix the problem, but I'm not 100% sure what would have caused it:

omf cd z
git submodule init
git submodule update

[lukasmalkmus]

Oh, I fucked up. I had z installed via brew. So removing z (brew) and then reinstalling your plugin worked fine.
Might be worth a note in the README!

Actually, I don't think it was your fault. I just reproduced it somehow in OS X without having z installed already.

It's like its trying to use z on cd before its even finished installing it. I'm not sure what is causing the plugin to load before it is done installing though.

I have the same problem on Debian Jessie with last version of omf and fish installed.
When I did your workaround, it worked despite the output I got just before after installing the plugin :

 ~ >  omf install z
