Last active June 23, 2022 03:42
bash: simplified custom function __git_ps1 to display current branch or tag name in git repo
#!/usr/bin/env bash
#
# If one is missing the original *__git_ps1* function from @git/git package, this wrapper can be utilized as
# temporary solution. Just like the original, it prints current branch name like *main*, *dev* etc. or tags
# like *v1.4.0*, or nothing, if current directory is outside of any git tree
#
# @see https://github.com/git/git/blob/master/contrib/completion/git-prompt.sh

# Significantly updated 06/18/2022
