Create Pull Request
[](https://github.com/peter-evans/create-pull-request/actions?query=workflow%3ACI)
[](https://github.com/marketplace/actions/create-pull-request)
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 steps in a workflow.
This action is designed to be used in conjunction with other steps 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
- tracked (modified) files
- commits made during the workflow that have not been pushed
2. Commit all changes to a new branch, or update an existing pull request branch.
3. Create a pull request to merge the new branch into the base—the branch checked out in the workflow.

## Usage
```yml
- name: Create Pull Request
uses: peter-evans/create-pull-request@v2
```
You can also pin to a [specific release](https://github.com/peter-evans/create-pull-request/releases) version in the format `@v2.x.x`
### Action inputs
All inputs are **optional**. If not set, sensible default values will be used.
**Note**: If you want pull requests created by this action to trigger an `on: push` or `on: pull_request` workflow then you cannot use the default `GITHUB_TOKEN`. See the [documentation here](https://github.com/peter-evans/create-pull-request/blob/master/docs/concepts-guidelines.md#triggering-further-workflow-runs) for workarounds.

| `request-to-parent` | Create the pull request in the parent repository of the checked out fork. See [push pull request branches to a fork](https://github.com/peter-evans/create-pull-request/blob/master/docs/concepts-guidelines.md#push-pull-request-branches-to-a-fork) for details. | `false` |
| `base` | Sets the pull request base branch. | Defaults to the branch checked out in the workflow. |
| `branch-suffix` | The branch suffix type. Valid values are `random`, `timestamp` and `short-commit-hash`. See [Action behaviour](#action-behaviour) for details. | |
### Action outputs
The pull request number is output as both an environment variable and a step output.
Note that in order to read the step output the action step must have an id.
```yml
- name: Create Pull Request
id: cpr
uses: peter-evans/create-pull-request@v2
- name: Check outputs
run: |
echo "Pull Request Number - ${{ env.PULL_REQUEST_NUMBER }}"
echo "Pull Request Number - ${{ steps.cpr.outputs.pull-request-number }}"
```
### Checkout
This action expects repositories to be checked out with `actions/checkout@v2`.
If there is some reason you need to use `actions/checkout@v1` the following step can be added to checkout the branch.
```yml
- uses: actions/checkout@v1
- run: git checkout "${GITHUB_REF:11}"
```
### Action behaviour
The default behaviour of the action is to create a pull request that will be continually updated with new changes until it is merged or closed.
Changes are committed and pushed to a fixed-name branch, the name of which can be configured with the `branch` input.
Any subsequent changes will be committed to the *same* branch and reflected in the open pull request.
How the action behaves:
- If there are changes (i.e. a diff exists with the checked out base branch), the changes will be pushed to a new `branch` and a pull request created.
- If there are no changes (i.e. no diff exists with the checked out base branch), no pull request will be created and the action exits silently.
- If a pull request already exists and there are no further changes (i.e. no diff with the current pull request branch) then the action exits silently.
- If a pull request exists and new changes on the base branch make the pull request unnecessary (i.e. there is no longer a diff between the base and pull request branch), the pull request is automatically closed and the branch deleted.
For further details about how the action works and usage guidelines, see [Concepts, guidelines and advanced usage](docs/concepts-guidelines.md).
#### Alternative strategy - Always create a new pull request branch
For some use cases it *may* be desirable to always create a new unique branch each time there are changes to be committed.
This strategy is not recommended and mainly kept for backwards compatibility.
To use this strategy, set input `branch-suffix` with one of the following options.
- `random` - Commits will be made to a branch suffixed with a random alpha-numeric string. e.g. `create-pull-request/patch-6qj97jr`, `create-pull-request/patch-5jrjhvd`
- `timestamp` - Commits will be made to a branch suffixed by a timestamp. e.g. `create-pull-request/patch-1569322532`, `create-pull-request/patch-1569322552`
- `short-commit-hash` - Commits will be made to a branch suffixed with the short SHA1 commit hash. e.g. `create-pull-request/patch-fcdfb59`, `create-pull-request/patch-394710b`
### 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.
### Committer and author
If neither `committer` or `author` inputs are supplied the action will default to making commits that appear to be made by the GitHub Actions bot user.
The following configuration can be used to have commits authored by the user who triggered the workflow event.
```yml
- name: Create Pull Request
uses: peter-evans/create-pull-request@v2
with:
committer: GitHub
author: ${{ github.actor }} <${{ github.actor }}@users.noreply.github.com>
```
### Controlling commits
As well as relying on the action to handle uncommitted changes, you can additionally make your own commits before the action runs.
```yml
steps:
- uses: actions/checkout@v2
- name: Create commits
run: |
git config user.name 'Peter Evans'
git config user.email 'peter-evans@users.noreply.github.com'
date +%s > report.txt
git commit -am "Modify tracked file during workflow"
date +%s > new-report.txt
git add -A
git commit -m "Add untracked file during workflow"
- name: Uncommitted change
run: date +%s > report.txt
- name: Create Pull Request
uses: peter-evans/create-pull-request@v2
```
### Create a project card
To create a project card for the pull request, pass the `pull-request-number` step output to [create-or-update-project-card](https://github.com/peter-evans/create-or-update-project-card) action.
```yml
- name: Create Pull Request
id: cpr
uses: peter-evans/create-pull-request@v2
- name: Create or Update Project Card
uses: peter-evans/create-or-update-project-card@v1
with:
project-name: My project
column-name: My column
issue-number: ${{ steps.cpr.outputs.pull-request-number }}
```
## Reference Example
The following workflow is a reference example that sets all the main inputs.
See [examples](docs/examples.md) for more realistic use cases.
```yml
name: Create Pull Request
on: push
jobs:
createPullRequest:

steps:
- uses: actions/checkout@v2
- name: Create report file
run: date +%s > report.txt
- name: Create Pull Request
id: cpr
uses: peter-evans/create-pull-request@v2
with:
token: ${{ secrets.GITHUB_TOKEN }}
commit-message: Add report file
committer: GitHub
author: ${{ github.actor }} <${{ github.actor }}@users.noreply.github.com>
title: '[Example] Add report file'
body: |
New report
- Contains *today's* date
- Auto-generated by [create-pull-request][1]

labels: report, automated pr
assignees: peter-evans
reviewers: peter-evans
team-reviewers: owners, maintainers
milestone: 1
draft: false

- name: Check outputs
run: |
echo "Pull Request Number - ${{ env.PULL_REQUEST_NUMBER }}"
echo "Pull Request Number - ${{ steps.cpr.outputs.pull-request-number }}"
