ZSH Prompt to show git branch
February 15th, 2008 | 1 comment
After using git for a little bit I started tinkering with ZSH, to get the current branch in my prompt.
What I ended up with is this:
Turns out it's pretty easy - somewhere in your .zshrc you need to put the following:
1 2 3 4 5 6 7 8 9 10 11 |
# get the name of the branch we are on
git_prompt_info() {
ref=$(git-symbolic-ref HEAD 2> /dev/null) || return
echo "(${ref#refs/heads/})"
}
autoload -U colors
colors
setopt prompt_subst
PROMPT='%{$fg_bold[green]%}%n@%m %{$fg[blue]%}%c %{$fg_bold[red]%}$(git_prompt_info)%{$fg[blue]%} %% %{$reset_color%}' |
The git_prompt_info function just asks git what branch we are in (and returns if we're not in a git repo), and then strips out regs/heads from the output. The colors bit is just so you can use colors like "green" instead of this awesomeness. prompt_subst is needed to tell zsh we want the git_prompt_info substituted with it's results, otherwise it will just show it as a string.
Thats pretty much it!
I initially had a right hand prompt for the branch, which while looks nicer, makes it less likely to be seen... My original prompt looked like this:
1 2 |
PROMPT='%{$fg_bold[green]%}%m %{$fg[blue]%}%c %% %{$reset_color%}'
RPROMPT='%{$fg_bold[yellow]%}$(git_prompt_info)%{$reset_color%}' |
Nice one!
I think I'll implement this later this day.
I still have to move all projects to git though.
