# Here we check your GitLab project settings and provide recommendations on which
# settings you should change, or how to decide what to choose.
# You need to have a variable called GL_TOKEN set, which contains a Project
# Access Token with read_api or api access.

# If you want problems to be automatically resolved, set the variable GITLAB_RECOMMENDED_AUTO_FIX to "true"

    RECOMMENDED_SETTINGS: |
      merge_requests_enabled:
        recommended: true
        hint: Enable merge requests.
      merge_method:
        recommended: merge
        hint:
          To ensure a full history of what happened with your code, never use fast
          forward. Set 'Merge method' to 'Merge commit'
      only_allow_merge_if_pipeline_succeeds:
        recommended: true
        hint:
          Only allow merging when the pipeline succeeds, to ensure no broken code can
          be merged.
      only_allow_merge_if_all_discussions_are_resolved:
        recommended: true
        hint:
          Ensure all discussions are resolved before merging. Tedious perhaps, but
          reduces mistakes.
      allow_merge_on_skipped_pipeline:
        recommended: false
        hint: Do not allow merging on skipped pipelines.
      remove_source_branch_after_merge:
        recommended: true
        hint:
          To keep your repo clean, remove source branches when merge requests are
          merged.
      autoclose_referenced_issues:
        recommended: true
        hint: Set auto close referenced issues.
