|
|
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.

|
- name: Create Pull Request
|
|
uses: peter-evans/create-pull-request@v3
|

```
|

|
|
|
|
### Action inputs
|
|
|
|
All inputs are **optional**. If not set, sensible defaults 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.
|
|
|

|
|
| `path` | Relative path under `GITHUB_WORKSPACE` to the repository. | `GITHUB_WORKSPACE` |
|
|
| `commit-message` | The message to use when committing changes. | `[create-pull-request] automated change` |

|
|
| `push-to-fork` | A fork of the checked out parent repository to which the pull request branch will be pushed. e.g. `owner/repo-fork`. The pull request will be created to merge the fork's branch into the parent's base. 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. | |

|
### Action outputs
|
|
|
|
The pull request number is output as 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@v3
|
|
- name: Check outputs
|
|
run: |
|
|
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 action creates 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).
|
|
|
|
### 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@v3
|
|
```
|
|
|
|
### 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.
|
|
|
|
### 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@v3
|
|
|
|
- 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 }}
|
|
```
|
|
|
|
