A GitHub action to create a pull request for changes to your repository in the actions workspace.

Changes to a repository in the actions workspace persist between actions in a workflow.
This action is designed to be used in conjunction with other actions that modify or add files to your repository.
The changes will be automatically committed to a new branch and a pull request created.

Create Pull Request action will:

1. Check for repository changes in the actions workspace. This includes untracked (new) files as well as modified files.
2. Commit all changes to a new branch. The commit will be made using the name and email of the `HEAD` commit author.
3. Create a pull request to merge the new branch into the currently active branch executing the workflow.

Note: Modifying a repository during workflows is not good practice in general.
However, this action opens up some interesting possibilities when used carefully.
This action is experimental and may not work well for some use cases.

## Usage

```yml
    - name: Create Pull Request
      uses: peter-evans/create-pull-request@v1.2.1
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

#### Environment variables

These variables are all optional. If not set, a default value will be used.

- `PULL_REQUEST_BRANCH` - The branch name. See **Branch naming** below for details.
- `BRANCH_SUFFIX` - Valid values are `short-commit-hash` and `timestamp`. See **Branch naming** below for details.
- `COMMIT_MESSAGE` - The message to use when committing changes.
- `PULL_REQUEST_TITLE` - The title of the pull request.
- `PULL_REQUEST_BODY` - The body of the pull request.

The following parameters are available for debugging and troubleshooting.

- `DEBUG_EVENT` - If present, outputs the event data that triggered the workflow.
- `SKIP_IGNORE` - If present, the `ignore_event` function will be skipped.

#### Branch naming

The variable `PULL_REQUEST_BRANCH` defaults to `create-pull-request/patch`.
Commits will be made to a branch with this name and suffixed with the short SHA1 commit hash.

e.g.
```
create-pull-request/patch-fcdfb59
create-pull-request/patch-394710b
```

Alternatively, branches can be suffixed with a timestamp by setting the environment variable `BRANCH_SUFFIX` to the value `timestamp`. This option may be necessary if multiple pull requests will be created during the execution of a workflow.

e.g.
```
create-pull-request/patch-1569322532
create-pull-request/patch-1569322552
```

#### Ignoring files

If there are files or directories you want to ignore you can simply add them to a `.gitignore` file at the root of your repository. The action will respect this file.

## Example

Here is an example that sets all the main environment variables.

```yml
    - name: Create Pull Request
      uses: peter-evans/create-pull-request@v1.2.1
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        PULL_REQUEST_BRANCH: my-patches
        BRANCH_SUFFIX: short-commit-hash
        COMMIT_MESSAGE: Auto-modify files by my-file-modifier-action
        PULL_REQUEST_TITLE: Changes from my-file-modifier-action
        PULL_REQUEST_BODY: This is an auto-generated PR with changes from my-file-modifier-action
```

This configuration will create pull requests that look like this:
