clone and symlink go open source project

goclone

#/!bin/bash
repository=github.com

if [ -z "$GOPATH" ] ; then
  echo '$GOPATH not set.'
  exit 1
fi

cd $GOPATH

if [ $# -lt 1 ] ; then
  echo "Usage: goclone group/project [repository]"
  exit 1
fi

if [ ! -z "$2" ] ; then
  repository=$2
fi

group=`echo $1 | cut -f1 -d"/"`
project=`echo $1 | cut -f2 -d"/"`

if [ -z "$project" ] || [ -z  "$group" ] ; then
  echo "Usage: goclone group/project [repository]"
  exit 1
fi

repo=$1
target=$GOPATH/src/$repository/$group

if [ ! -d $target ] ; then
  mkdir -p $target

  echo "Created folder "$target
fi

cd $target

git clone git@$repository:$repo.git

if [ $? -ne 0 ] ; then
  echo "Could not clone repository"
  exit 1
fi

symlink=$project

cd $GOPATH
ln -s $target/$project _$symlink

this small snippet checks out any go project to the correct destination in your gopath and creates a symlink to fast access it.

It should be placed within your $PATH environment variable.

goclone go-mgo/mgo will then create a symlink $GOPATH/_mgo which points to $GOPATH/src/github.com/go-mgo/mgo

This is particulary useful on own projects.

you might find adding something like:

# First path
GOPATH=$(echo $GOPATH | cut -d":" -f1)

or

# Last path
GOPATH=$(echo $GOPATH | rev | cut -d":" -f1 | rev)

helpful. I ended up using last path so that by default go get would dump into my pkgenv but goclone would dump into my go workspace.

you can use motemen/ghq.
