Original GitHub issue: https://github.com/nektos/act/issues/970

System information

- Operating System: macOS
- Architecture: x64 (64-bit)
- Apple M1: no
- Docker version: 20.10.12
- Docker image used in `act`: < can be omitted if it's included in log >
- `act` version: 0.2.25

Expected behaviour

There is a github env called GITHUB_REF_NAME

Actual behaviour

env.GITHUB_REF_NAME is not set

check https://github.com/nektos/act/blob/master/pkg/runner/run_context.go, it seems that the supported env in act is not the same to the recent documentation: https://docs.github.com/en/actions/learn-github-actions/environment-variables#default-environment-variables

Workflow and/or repository

Get ${{ env.GITHUB_REF_NAME }} in steps

Steps to reproduce

Get ${{ env.GITHUB_REF_NAME }} in steps

`act` output

+1 — Would be nice to have echo ${GITHUB_REF_NAME} behave similar to echo ${GITHUB_REF}

Thanks for this great tool by the way 🙏

@ChristopherHX I'd be happy to open a PR for this.

Is it pretty much adding an additional line here?
github.com/nektos/act@3f2469bf53/pkg/runner/run_context.go (L626)

  env["GITHUB_REF"] = github.Ref
+ env["GITHUB_REF_NAME"] = github.RefName

@ChristopherHX commented on GitHub (Apr 26, 2022):

This also needs to be added there
github.com/nektos/act@3f2469bf53/pkg/model/github_context.go (L20)
Populated here based on github.ref without refs/heads/ or refs/tags/.
github.com/nektos/act@3f2469bf53/pkg/runner/run_context.go (L552)
I would add it together with github.ref_type

I already do this in my act replacement backed by the official actions/runner:
github.com/ChristopherHX/runner.server@565a185a74/src/Runner.Server/Controllers/MessageController.cs (L939-L940)
