Rebase

A GitHub action to rebase pull requests in a repository.

Usage

The default behaviour of the action with no configured inputs is to check the current repository for rebaseable pull requests and rebase them. Pull requests from forks are rebaseable only if they allow edits from maintainers.

      - uses: peter-evans/rebase@v3

Periodically rebase all pull requests

The simplest way to use this action is to schedule it to run periodically.

name: Rebase
on:
  schedule:
    - cron:  '0 0 * * *'
jobs:
  rebase:
    runs-on: ubuntu-latest
    steps:
      - uses: peter-evans/rebase@v3

Rebase all pull requests on push to the base branch

name: Rebase
on:
  push:
    branches: [main]
jobs:
  rebase:
    runs-on: ubuntu-latest
    steps:
      - uses: peter-evans/rebase@v3
        with:
          base: main

Exclude pull requests with specific labels

      - uses: peter-evans/rebase@v3
        with:
          exclude-labels: |
            no-rebase
            dependencies

Exclude pull request forks with head filter

      - uses: peter-evans/rebase@v3
        with:
          head: 'my-org:*'

Action inputs

Name	Description	Default
token	GITHUB_TOKEN or a repo scoped PAT. The workflow scope may also be required if rebasing pull requests containing changes to workflows under .github/workflows.	GITHUB_TOKEN
repository	The target GitHub repository containing the pull request.	github.repository (Current repository)
head	Filter pull requests by head user or head organization and branch name in the format user:ref-name or organization:ref-name. Use the * wildcard match any ref. e.g. my-org:new-script-format or octocat:*.
base	Filter pull requests by base branch name. Example: gh-pages.
include-labels	A comma or newline separated list of pull request labels to include. Allows any labels if unspecified.
exclude-labels	A comma or newline separated list of pull request labels to exclude.
exclude-drafts	Exclude draft pull requests.	false
rebase-options	A comma or newline separated list of options to pass to the git rebase command. For example, -Xtheirs.

Rebase slash command

Use the following two workflows and a repo scoped PAT to add a /rebase slash command to pull request comments. The slash-command-dispatch action makes sure that the command is only executable by users with write access to the repository.

name: Slash Command Dispatch
on:
  issue_comment:
    types: [created]
jobs:
  slashCommandDispatch:
    runs-on: ubuntu-latest
    steps:
      - name: Slash Command Dispatch
        uses: peter-evans/slash-command-dispatch@v3
        with:
          token: ${{ secrets.PAT }}
          commands: rebase
          permission: write
          issue-type: pull-request

name: rebase-command
on:
  repository_dispatch:
    types: [rebase-command]
jobs:
  rebase:
    runs-on: ubuntu-latest
    steps:
      - uses: peter-evans/rebase@v3
        id: rebase
        with:
          head: ${{ github.event.client_payload.pull_request.head.label }}
      - name: Add reaction
        if: steps.rebase.outputs.rebased-count == 1
        uses: peter-evans/create-or-update-comment@v1
        with:
          token: ${{ secrets.PAT }}
          repository: ${{ github.event.client_payload.github.payload.repository.full_name }}
          comment-id: ${{ github.event.client_payload.github.payload.comment.id }}
          reaction-type: hooray

Target other repositories

You can rebase requests in another repository by using a repo scoped PAT instead of GITHUB_TOKEN. The user associated with the PAT must have write access to the repository.

This example targets multiple repositories.

name: Rebase
on:
  schedule:
    - cron:  '0 0 * * *'
jobs:
  rebase:
    strategy:
      matrix:
        repo: ['my-org/repo1', 'my-org/repo2', 'my-org/repo3']
    runs-on: ubuntu-latest
    steps:
      - uses: peter-evans/rebase@v3
        with:
          token: ${{ secrets.PAT }}
          repository: ${{ matrix.repo }}
