Hello @troian

isn't it already implemented in go1.21's go.mod as toolchain option?

i don't think so, because we still have to use the action with the versions prior 1.21 and toolchain option is different in the mean it can call out for different go versions used for build/test/lint tasks. But thank you for pointing out this new feature - it should be incorporated into the action. It would be good to create the feature request .

@dsame is this still planned? It's been nearly a year since the last update.

For everyone like me who found this PR while trying to get actions/setup-go working with .tool-versions, here's the solution we've settled on:

steps:
  - uses: actions/checkout@v4
  - id: go-version
    run: echo "go-version=$(cat .tool-versions | grep golang | cut -d ' ' -f 2)" >> "$GITHUB_OUTPUT"
  - uses: actions/setup-go@v5
    with:
      go-version: ${{ steps.go-version.outputs.go-version }}
