# This workflow is run for commits in PRs (from branches in forks), commits
# (from branches in main repo, usually main branch) and tags. Unfortunately,
# there are only two properties in the github context that can be used here:
# - workflow_run.event is "pull_request" for PRs and "push" otherwise
# - workflow_run.head_branch contains the branch or tag name
# We can not reliably identify a tag from that, so we simply match the
# head_branch against the naming pattern of our tags ("cvc5-*"). To prevent PRs
# with a matching branch name to be recognized as tags, we proceed as follows:
# - handle PRs (event == "pull_request")
# - handle tags (head_branch == "cvc5-*")
# - rest are regular commits
