A helper tool to set up a unique $GOPATH for each project I work directly on.

go-get-project.sh

#!/usr/bin/env sh

set -e

development_root=~/dev
goimports="golang.org/x/tools/cmd/goimports"
golint="github.com/golang/lint/golint"
gocode="github.com/nsf/gocode"

if [[ "$#" -ne 1 ]]
then
    echo "error: $0 requires the go-gettable project name as an argument"
    exit 1
fi

echo "Setting up GOPATH for project $1"
oldGOPATH="${GOPATH}"
proj_name=$(basename "$1")
GOPATH="${development_root}/${proj_name}"
if [[ -e "${GOPATH}" ]]
then
    echo "error: ${GOPATH} exists"
    exit 1
fi

mkdir "${GOPATH}"
touch "${GOPATH}/.gopath"
ln -s ~"/.emacs.d/gopath-dir-locals.el" "${GOPATH}/.dir-locals.el"

export GOPATH
echo "Installing goimports"
go get "${goimports}"
echo "Installing golint"
go get "${golint}"
echo "Installing gocode"
go get "${gocode}"
echo "Installing $1"
go get "$1"
if [[ "${oldGOPATH}" != "" ]]
then
    export GOPATH="${oldGOPATH}"
else
    unset GOPATH
fi
echo "Done."
