| # This workflow is used to create PRs to merge changes from the main branch to the next branch. It's mostly a front-end | |
| # to `flub merge branches`, which is where the source code can be found. This also means you can replicate this workflow | |
| # manually by running `flub merge branches` locally and providing a PAT. | |
| # | |
| # When run, the workflow executes `flub merge branches`, which first checks if a main/next merge PR is already open. If | |
| # it is, the workflow exits with no error. | |
| # | |
| # If there is no PR, then the tool will open one by following this logic | |
| # | |
| # - Find the commits that need to be merged into next. | |
| # - Take a batch of commits and iterate over them. | |
| # - Test each commit for mergeability into next. | |
| # - If all commits merge cleanly, open a PR at the last commit in the batch. | |
| # - If a commit cannot be merged cleanly, open a PR at the _previous_ commit. | |
| # - Once that PR is merged, then the next time the workflow runs, it will detect the conflicting commit and open a PR | |
| # with that commit only. | |
| # | |
| # Each time the workflow runs, the tool will determine the commits to merge based entirely on the git repo state. | |
