Github action to retrieve branch or tag names with support for all events.
Get a branch or tag name without the /ref/* prefix.
- Retrieve the current branch name without any prefix. (e.g.
'refs/heads/main'->'main') - Retrieve the current tag with an option to strip the prefix (e.g.
v0.0.1->v->0.0.1) - Detect actions triggered by non default branches
- Detect actions triggered by the default branch
- Supports all valid git branch names

| default_branch | string | The default branch name e.g main OR master |
| head_ref_branch | string | The source branch of a pull request e.g feature/test |
| is_default | string | Returns "true" if the current branch is the default else "false". |
| is_tag | string | Returns "true" if the current branch is a tag else "false". |
| ref_branch | string | The branch that triggered the workflow run. e.g 1/merge, main |
