Subject: Shortened bit branch in prompt
Date: Wed, 10 Feb 2021 13:05:01 +0100 [thread overview]
Message-ID: <20210210120501.GA3727@gmx.de> (raw)
I have this function to put the name of the current git branch in
the shell prompt if the working directory is inside a git tree:
--
__git_ps1 () {
local b="$(
git symbolic-ref -q HEAD 2> /dev/null ||
{ [[ $? == 1 ]] && printf '*none*'} )"
if [[ -n "$b" ]]
then
printf " (%s)" "${${b##refs/heads/}:0:25}" <---------------
fi
}

Since a customer uses absurdly long branch names, it uses only the
first 25 characters of the name.
I want to change that so
* If the branch name is max. 25 characters, print it umodified.
* If the branch ame is loger, print
<first 17 characters>...<last five characters>
E.g. if the branch name is abcdefghijklmnopqrstuvwxyz0123456789,
the prompt should have
abcdefghijklmnopq...56789
Of course this should be done with zsh functionality only.
Ciao
Dominik ^_^ ^_^
