Git Get

git-get

#!/bin/bash -x
#
# Clones Git Projects into directory of <projects_dir>/<group>/<repo_name>
#
# Tested with support for Github, Bitbucket & Sourcehut.
#
# By default, clones to $HOME/projects. This can be overriden by setting
# GIT_GET_PROJECTS_DIR to another directory.
#
# Usage:
#
#   git get https://github.com/foo/bar.git
#   git get git@github.com:foo/bar.git
#

PROJECTS_DIR=${GIT_GET_PROJECTS_DIR:-"$HOME/projects"}

# Regex to extract group & project from projects. Tested with these patterns to
# extract group=foo and repo_name=bar.
#
#    https://github.com/foo/bar.git
#    git@github.com:foo/bar.git
#    https://bitbucket.org/mituharu/emacs-mac.git
#    git@git.sr.ht:~foo/bar
