'tcsh' Git prompt to show current branch

gistfile1.tcsh

# in ~/bin/gitprompt.csh:

setenv GIT_BRANCH_CMD "sh -c 'git branch --no-color 2> /dev/null' | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1) /'"
set prompt="%m:%~ `$GIT_BRANCH_CMD`%B%#%b "

# and then in ~/.cshrc:

alias precmd "source ~/bin/gitprompt.csh"

LOVE this!

I modify it like this, with lots of colors and a simplified sed:
setenv GIT_BRANCH_CMD "sh -c 'git rev-parse --abbrev-ref HEAD 2> /dev/null' | sed -e 's/(.*)/(\1) /'"
set prompt="%{\033[34m%}%n@%B%m%b %B%{\033[31m%}%~%b %{\033[36m%}$GIT_BRANCH_CMD%{\033[39m%}%h ) "

Good working solution, Thanks for it!

Just two remarks:

• created file needs to have proper rights (chmod 755), otherwise it will not work
• for colors I find easier to use aliases. see https://www.cs.umd.edu/~srhuang/teaching/code_snippets/prompt_color.tcsh.html

so this is my version so far:

echo "colors"
set red="%{\033[1;31m%}"
set green="%{\033[0;32m%}"
set yellow="%{\033[1;33m%}"
set blue="%{\033[1;34m%}"
set magenta="%{\033[1;35m%}"
set cyan="%{\033[1;36m%}"
set white="%{\033[0;37m%}"
set end="%{\033[0m%}" # This is needed at the end...

setenv GIT_BRANCH_CMD "sh -c 'git branch --no-color 2> /dev/null' | sed -e '/^[^*]/d' -e 's/* (.*)/(\1) /'"
set prompt="${green}%n@%m:${yellow}%~${cyan} $GIT_BRANCH_CMD%B\n${white}%#%b${end}"

echo "cleaning"
unset red green yellow blue magenta cyan yellow white end

Its much cleaner if you use git branch --show-current, no need for the parsing, this will also work with multiple git worktrees.

Be aware that git branch --show-current only works for git version 2.22 or later. This may be useful to know in some slow-moving corporate environments.
