Get branch or tag information without the `/ref/*` prefix
## Features
* 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](https://wincent.com/wiki/Legal_Git_branch_names)
## Usage
```yaml
on:
push:
branches:
- main
pull_request:
branches:
- main
...
steps:
- name: Get branch name
id: branch-name
uses: tj-actions/branch-names@v5.1
- name: Running on the default branch.
if: steps.branch-name.outputs.is_default == 'true'
run: |
echo "Running on default: ${{ steps.branch-name.outputs.current_branch }}"
# Outputs: "Running on default: main".
- name: Running on a pull request branch.
if: steps.branch-name.outputs.is_default == 'false'
run: |
echo "Running on pr: ${{ steps.branch-name.outputs.current_branch }}"
# Outputs: "Running on pr: feature/test".
```

| OUTPUT | TYPE | DESCRIPTION |
|-----------------|--------|-------------------------------------------------------------------------------------------------------------------------------|
| base\_ref\_branch | string | The target branch of a
pull request e.g main |
| current\_branch | string | Returns the value of the
current branch which is consistent
regardless of event\_type e.g main,
feature/test, v0.0.1. |
| default\_branch | string | |
| 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
|
| tag | string | The tag that triggered the
workflow run. e.g v0.0.1, 0.0.1
|
## Inputs
| INPUT | TYPE | REQUIRED | DEFAULT | DESCRIPTION |

-> 0.0.1 |
