## Open GitKraken using the current repo directory.
## This code is for fish shell. The same thing can be done in bash
## by creating an alias with the command below.

## `1>/dev/null` directs logs from the terminal
## `&` allows use of the same terminal instance to do other things

## Note: If you're not using OSX, the path is definitely different.

function kraken
  set dir $argv[1] (pwd) # use a directory if you pass it in, otherwise cwd
  /Applications/GitKraken.app/Contents/MacOS/GitKraken -p $dir 1>/dev/null &
end

## Now you can simply run `kraken` from your git repo directory.
## Optionally specify the directory of your git repo as the first parameter.

I'm using Ubuntu 16.10 and I have Git Kraken 2.5.0 installed, so I don't need to create a new function because if I execute gitkraken into terminal the app will run.

would you please, help me to customize it for zsh
i tried

gitkraken() {
	set dir $1 (pwd)
	/Applications/GitKraken.app/Contents/MacOS/GitKraken -p $dir 1>/dev/null &
}

but it tell me
gitkraken:1: number expected

for zsh, i added this to .zshrc

gitkraken() {
	if [ "$1" != "" ]
    then
		/Applications/GitKraken.app/Contents/MacOS/GitKraken -p $1 1>/dev/null &
	else
		/Applications/GitKraken.app/Contents/MacOS/GitKraken -p . 1>/dev/null &
	fi
}

and it worked

the problem with this one is that after closing gitkraken
zsh is using 100% CPU

i don't now where is the problem

I wrote a version in go go get github.com/mrexodia/kraken

What the difference between this gist and https://gist.github.com/dersam/0ec781e8fe552521945671870344147b ?

@skywinder this is a forked version for fish shell. That one is for z shell.
