Git Branch Terminal Prompt for zsh (MacOS Catalina)

function parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}

setopt PROMPT_SUBST
export PROMPT='%{%F{245}%}%n %{%F{normal}%}%2~ %{%F{green}%}$(parse_git_branch) %{%F{normal}%}$%{%f%} '

For anyone who comes here looking for the fix this bit of code offers, but wants to play around with colors, but isn't a ZSH-pro like I am (or wasn't before I went on this kick to find out about colors...). I used the colors from the reference link, because I liked them. 😅

export PROMPT='%F{243}%n%f %F{197}%~%f %F{39}$(parse_git_branch)%f %F{normal}$%f '

The ZSH feature of %F{...} thingToBeColored %f is handy, but it was tough to break it down to understand what was going on. It takes a color name, such as normal or green, but it also takes an ANSI color code...number? Not sure what it's called, but

ANSI color code of red is \u001b[31m, but the 31 is what you'd pass into the &F{31}IamCool%f to make IamCool red.

This might be a "no duh" thing for others, but I figured I'd leave a little bit of what I found.

Also, for the sake of demonstrating the history:

You'll run into weird issues of lines wrapping and messing up unexpectedly.

This is a fix for that:

export PROMPT='%{%F{243}%}%n %{%F{197}%}%~ %{%F{39}%}$(parse_git_branch) %{%F{normal}%}$%{%f%} '

Note the use of %{...%} to make sure that formatting characters aren't being counted in the character count of the line. If someone comes across this and finds a better way to do it, please definitely improve this.

I found this stackover flow helpful to start to see what was up: https://stackoverflow.com/questions/689765/how-can-i-change-the-color-of-my-prompt-in-zsh-different-from-normal-text

Thanks @neiloler - This fix was very helpful and the tips re color was a good add-on. It's easy to choose colors of choice for username, directory path, git branch etc in that order
'${COLOR_USR}%n ${COLOR_DIR}%~ ${COLOR_GIT}$(parse_git_branch)${COLOR_DEF} $ '

Thanks for your feedback! @neiloler
