Configuring commit merging for pull requests

You can enforce, allow, or disable merging with a merge commit for all pull request merges on GitHub.com in your repository.

You can configure pull request merge options on GitHub.com to meet your workflow needs and preferences for managing Git history. For more information, see "Configuring pull request merges."

  1. On GitHub.com, navigate to the main page of the repository.

  2. リポジトリ名の下の [ 設定] をクリックします。 リポジトリの設定ボタン

  3. Under "Pull Requests", select Allow merge commits. This allows contributors to merge a pull request with a full history of commits. Screenshot of Pull Request settings with allow merge commits checkbox emphasized

  4. Optionally, under Allow merge commits, use the dropdown to choose the format of the commit message presented to contributors when merging. The default message includes the pull request number and title. For example, Merge pull request #123 from patch-1. You can also choose to use just the pull request title, or the pull request title and description. Screenshot of emphasized default commit message dropdown

If you select more than one merge method, collaborators can choose which type of merge commit to use when they merge a pull request. コミットの線形履歴を必要とする保護されたブランチ ルールがリポジトリにある場合、スカッシュ マージ、リベース マージ、あるいはその両方を許可しなければなりません。 詳細については、「保護されたブランチについて」を参照してください。
