Getting the source branch on a pull_request event and the pushed branch on a push event

[elongl]

I want a way to get the branch name (not <NUM>/pull, or <NUM>/merge, etc.) of the source branch on a PR and the pushed branch when pushing.

Initially I thought that github.ref_name would give me that but instead it returned 270/merge and not the PR's branch name.
I then started using github.head_ref, but it only applies to PRs and not to pushed branches.

What's an expression that would evaluate to github.head_ref on PR and to the pushed branch on a push event?

Thanks.

github.event.pull_request.head.ref ?

Hi,
maybe
github.base_ref - The base_ref or target branch of the pull request in a workflow run. This property is only available when the event that triggers a workflow run is either pull_request or pull_request_target

You can check github context to see what else is available https://docs.github.com/en/actions/learn-github-actions/contexts#github-context.

I ended up using BRANCH_NAME: ${{ github.head_ref || github.ref_name }} but I'm not sure if this is the best way, works for now.

This does not work and is an empty value on PR merge.

is there any fix for this? push request would be a lot more useful with github.head_ref variable :)

i need it too, i want scrap branch name to set labels in pull request template

[syedammadiqbal]

To get source branch Name : ${{github.ref_name}}
For Target branch Name : ${{github.event.pull_request.base.ref}}

I have tired to retrieve Branch name from the merge commit message on a push event and it's working for me.

# Get the Branch Name
MERGE_COMMIT_MESSAGE=$(git log --format=%B -n 1 "${GITHUB_SHA}")
BRANCH_NAME=$(echo "$MERGE_COMMIT_MESSAGE" | grep -oP '(?<=from ).*' | awk -F/ '{print $NF}')
echo "Branch Name: $BRANCH_NAME"
