Add $GOPATH/bin to $PATH

When installing tools via go get (e.g. golint) they can not be ran without adding $GOPATH/bin to $PATH beforehand.

So for using e.g. golint one would need to write a step:

- run: |
    export PATH=$PATH:$(go env GOPATH)/bin
    go get -u golang.org/x/lint/golint
    golint -set_exit_status ./...

It would be cool, if setup-go could already do the export PATH=$PATH:$(go env GOPATH)/bin part, as this is a common need.

I think you’re overthinking this. The official Go docker images simply hard-code PATH, as you can see here: https://github.com/docker-library/golang/blob/3a6407a6ff134ef6a0364ac061b0808f990ea14e/1.13-rc/alpine3.10/Dockerfile#L59-L60

Why not do the same? If anyone wants to set up a custom GOPATH or GOBIN, they can set up a custom PATH too. I’d prefer PATH to be simple and predictable.

I prefer this solution below. This works on windows, ubuntu, and mac.

    steps:
    - name: setup go
      uses: actions/setup-go@v1
      with:
        go-version: 1.x
    - name: setup env
      run: |
        echo "::set-env name=GOPATH::$(go env GOPATH)"
        echo "::add-path::$(go env GOPATH)/bin"
      shell: bash
    - name: checkout
      uses: actions/checkout@v1
      with:
        fetch-depth: 1
        path: src/github.com/${{ github.repository }}
