Set up your GitHub Actions workflow with a specific version of Go

Add 'go-version' Output (#85)
* Add go-version to action outputs

This provides the semver version of Go that has been installed. This is useful
if only a major or minor version has been provided as the input go-version
value.

* Convert version extraction to a function

Simplify how the version is extracted and add a simple test at the same
time.

setup-go

build-test Validate 'setup-go'

This action sets up a go environment for use in actions by:

  • Optionally downloading and caching a version of Go by version and adding to PATH.
  • Registering problem matchers for error output.

V3

The V3 edition of the action offers:

  • Adds GOBIN to the PATH
  • Proxy support
  • Check latest version
  • Bug fixes (including issues around version matching and semver)

The action will first check the local cache for a version match. If a version is not found locally, it will pull it from the main branch of the go-versions repository. On miss or failure, it will fall back to downloading directly from go dist. To change the default behavior, please use the check-latest input.

Matching by semver spec:

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '^1.13.1' # The Go version to download (if necessary) and use.
  - run: go version
steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '>=1.17.0'
  - run: go version

Matching an unstable pre-release:

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '1.18.0-rc.1' # The Go version to download (if necessary) and use.
  - run: go version
steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '1.16.0-beta.1' # The Go version to download (if necessary) and use.
  - run: go version

Usage

See action.yml

Basic

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '1.16.1' # The Go version to download (if necessary) and use.
  - run: go run hello.go

Check latest version

The check-latest flag defaults to false. Use the default or set check-latest to false if you prefer stability and if you want to ensure a specific Go version is always used.

If check-latest is set to true, the action first checks if the cached version is the latest one. If the locally cached version is not the most up-to-date, a Go version will then be downloaded. Set check-latest to true if you want the most up-to-date Go version to always be used.

Setting check-latest to true has performance implications as downloading Go versions is slower than using cached versions.

steps:
  - uses: actions/checkout@v3
  - uses: actions/setup-go@v3
    with:
      go-version: '1.14'
      check-latest: true
  - run: go run hello.go

Matrix testing

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        go: [ '1.14', '1.13' ]
    name: Go ${{ matrix.go }} sample
    steps:
      - uses: actions/checkout@v3
      - name: Setup go
        uses: actions/setup-go@v3
        with:
          go-version: ${{ matrix.go }}
      - run: go run hello.go

Supported version syntax

The go-version input supports the following syntax:

  • Specific versions: 1.15, 1.16.1, 1.17.0-rc.2, 1.16.0-beta.1
  • SemVer's version range syntax: ^1.13.1, >=1.18.0-rc.1

For more information about semantic versioning, please refer to semver documentation.
