gh-clone

GitHub clone repo util

Very simple bash function that let you quickly clone git your repositories stored on GitHub.

Ah, and it is also my first bash literate programming experiment. Do not edit fun.sh, run instead make fun to generate source from this file.

See also bb-clone twin project, which do the same but on Bitbucket.

Annotated source

gh-clone expects one parameter, otherwise prints its usage

if [ -z "$1" ]
then
	cat <<-EOF
	# GitHub clone repo util
	##
	# Installation instructions, source and license available here:
	# https://github.com/fibo/gh-clone#gh-clone
	##
	USAGE: gh-clone [user/]repo
	EOF
	return 0
fi

Repos will be cloned under folder $GITHUB_DIR which defaults to ~/github.com.

GITHUB_DIR=${GITHUB_DIR:-~/github.com}

MY_GITHUB_USER is prompted once, if not already configured.

MY_GITHUB_USER=$(git config --global github.user)
if [ -z "$MY_GITHUB_USER" ]
then
	read -p "Enter your github.user: " MY_GITHUB_USER
	git config --global github.user $MY_GITHUB_USER
fi

Parse parameter which can be given in the form $GITHUB_USER/$REPO_NAME or just $REPO_NAME.

GITHUB_USER=$(echo $1 | cut -d / -f1)
REPO_NAME=$(echo $1 | cut -d / -f2)

In the latter case $GITHUB_USER defaults to $MY_GITHUB_USER.

if [ "$REPO_NAME" == "$GITHUB_USER" ]
then
	GITHUB_USER=$MY_GITHUB_USER
fi

Clone repo under $GITHUB_DIR/$GITHUB_USER/$REPO_NAME and cd into it. Use git clone --recursive to initialize and updated submodules.

TARGET_DIR=$GITHUB_DIR/$GITHUB_USER
mkdir -p $TARGET_DIR
cd $TARGET_DIR
REPO_URL=git@github.com:$GITHUB_USER/${REPO_NAME}.git
git clone --recursive $REPO_URL && cd $REPO_NAME

Bonus feature: run yarn install or npm install if it looks like a Node project.

if [ -e package.json ]
then
  if [ -e yarn.lock ]
  then
    YARN=$(which yarn 2> /dev/null)
    if [ ! -z "$YARN" ]
    then
      $YARN install
    fi
  else
    NPM=$(which npm 2> /dev/null)
    if [ ! -z "$NPM" ]
    then
      $NPM install
    fi
  fi
fi

… and run bower install if there is a bower.json anb bower is found in your PATH.

Clean up
