# Install Go

I prefer install using tarball under home ~/app over using installer or brew.

First go to https://golang.org/dl/ and find the latest version

cd ~/Downloads
wget https://dl.google.com/go/go1.11.4.darwin-amd64.tar.gz
tar -zxf go1.11.4.darwin-amd64.tar.gz
mkdir ~/app
mv go ~/app

Second set your workspace, I just use ~/workspace

mkdir -p ~/workspace/bin
mkdir -p ~/workspace/src

Cofig PATH and GOPATH, add the following to your ~/.env.sh so the go command and go install can work

export GOROOT=$HOME/app/go
export GOPATH=$HOME/workspace
export PATH=$GOROOT/bin:$PATH
export PATH=$GOPATH/bin:$PATH

# Install dependency management

Since go1.11.2 go mod is official, however some projects are still using dep or even glide

Glide is no longer maintained, the latest and last release is 0.13.2. If you have problem accessing private repo using glide where password prompt pops up in parallel when using zsh, you can open a bash.

# install glide to you GOPATH use binary release
curl -sSL https://github.com/Masterminds/glide/releases/download/v0.13.2/glide-v0.13.2-darwin-amd64.tar.gz | tar -vxz -C /tmp --strip=1
# move it to $GOPATH/bin
mv /tmp/glide $GOPATH/bin/glide && glide -v

Dep haven't release for a while but there were some fixes on import logic, so just install it from source.

go get -u -v github.com/golang/dep/cmd/dep

Mod is built in, you need to enable it will GO111MODULE=on when you run it under GOPATH, if will be opt-in by default in future versions

go help mod

# Install lint tools

go get -u -v golang.org/x/tools/cmd/goimports
