How to get git-completion.bash to work on Mac OS X?

Question

I have followed http://blog.bitfluent.com/post/27983389/git-utilities-you-cant-live-without to add git-completion.bash to my /opt/local/etc/bash_completion.d/git-completion

and I put PS1='\h:\W$(__git_ps1 "(%s)") \u\$ ' in my .bashrc_profile

But now I am getting this -bash: __git_ps1: command not found everything I do a cd.

Can you please tell me what am I missing?

Solution 1

I installed git using MacPorts on my new Snow Leopard installation. After MacPorts is installed from the .dmg image, these would be the commands in Terminal.app:

sudo port selfupdate
sudo port install git-core +bash_completion

If you also want support for pulling from SVN repositories and docs, use this instead of the second line:

sudo port install git-core +bash_completion +doc +svn

Then add the following to your ~/.profile or ~/.bash_profile:

# MacPorts Bash shell command completion
if [ -f /opt/local/etc/bash_completion ]; then
    . /opt/local/etc/bash_completion
fi

or for MacPorts since version 2.1.2 on Mountain Lion:

# MacPorts Bash shell command completion
if [ -f /opt/local/etc/profile.d/bash_completion.sh ]; then
  . /opt/local/etc/profile.d/bash_completion.sh
fi

or for MacPorts with newer versions of git:

if [ -f /opt/local/share/git-core/git-prompt.sh ]; then
    . /opt/local/share/git-core/git-prompt.sh
fi

Note: bash 4.1 or higher is required by bash_completion.sh. If completion doesn't work try echo $BASH_VERSION to see if that's the issue. If so, enter MacPorts bash by typing bash and try git completion again.

Solution 2

If you installed git using homebrew than you might adjust the MacPorts advice a little and add this to your .bash_profile and .bashrc

if [ -f `brew --prefix`/etc/bash_completion.d/git-completion.bash ]; then
. `brew --prefix`/etc/bash_completion.d/git-completion.bash
fi

The best way to check if you have git correctly installed using homebrew ist to execute

brew info git

and check the output for the install directory of the git bash completion

Latest version of Git (1.7.12) also requires the following to enable the prompt.

if [ -f `brew --prefix`/etc/bash_completion.d/git-prompt.sh ]; then
    . `brew --prefix`/etc/bash_completion.d/git-prompt.sh
fi

Solution 3

All you need to do is place the git-completion.bash file in your user home bin directory and place the following in you .profile or .bash_profile file:

export PATH="$HOME/bin:$PATH"
source ~/bin/git-completion.bash
PS1='[\u@\h \w$(__git_ps1 " (%s)")]\$ '

What this does is make sure that your local bin is in the PATH and the source command gets things going. Then of course the PS1 change puts the currently checked out branch in the prompt.

So, no MacPort install to then install a the "completion" version of GIT (especially irritating if you already have it installed).

Solution 4

While the current answer is correct for older MacPorts there is a new issue with the most current MacPorts resulting in the same error.

The current bash-completion package (2.0 r1) requires at least a bash 4.1 to function properly. As a usual OS X Terminal uses /bin/bash it only gets a 3.x. You have to change you terminal settings to use /opt/local/bin/bash -l as described in the MacPorts documentation here: http://trac.macports.org/wiki/howto/bash-completion

Solution 5

You need to source the command completion functions. Add to your .bashrc_profile before the PS1:

. /opt/local/etc/bash_completion.d/git-completion

More precisely, git-completion.bash just needs to be somewhere in your $PATH. I decided to put mine in /usr/local/bin/ so that I didn't have to modify my existing $PATH.

I just copy pasted, and I still get the error the OP has. =\. How do you tell what's been included? I don't thenk bash_completion is sourced

[vitch]

This is the most correct answer as I only started having the problem after updating macports. The only downside to using the macports bash from terminal is that it now warns me about terminating running processes when I try to close my terminal window - have you run into this?

note with newer versions of git/macport/bash-completion the prompt is in a different file. See: trac.macports.org/ticket/36334 if [ -f /opt/local/share/git-core/git-prompt.sh ]; then . /opt/local/share/git-core/git-prompt.sh fi

Thanks a lot. It should be brew install bash-completion git-extras though (dash instead of underscore).

Because /opt/local/etc/profile.d/bash_completion.sh needs $BASH_VERSION 4.1 or better, I had to do the following on a Mac OS X 10.8.3 with MacPorts 2.1.3: Switch the Mac OS X login shell from its default /bin/bash (3.2.48(1)-release) to MacPorts /opt/local/bin/bash (4.2.42(2)-release) like its described here: stackoverflow.com/a/791244/287984. Basically if [ `grep /opt/local/bin/bash /etc/shells` ]; then echo /opt/local/bin/bash | chsh -s /opt/local/bin/bash; else echo /opt/local/bin/bash | sudo tee -a /etc/shells; chsh -s /opt/local/bin/bash; fi

[bgs]

Worked great for me. Had to replace /bin/bash in Terminal.app with /opt/local/bin/bash from macports + all the .bash_profile changes suggested here.

git-completion.bash can be found here: raw.github.com/git/git/master/contrib/completion/…

To move to bash 4.1 or later you can follow the instructions here: apple.stackexchange.com/questions/70132/…

This was the only answer that actually worked for me. Other answers were producing strange errors when you type an incomplete command like git br<TAB>

[cglacet]

Wow, I didn't even knew this came along with git when installed with homebrew. They should automatically append this to ~/.bash_profile, I wonder who wouldn't want this.
