fast-forward-action

Adds a fast-forward label to PRs and fast-forwards them on /fast-forward comment.

Use case

Github Web UI does not allow fast-forwarding of PRs:

https://stackoverflow.com/questions/60597400/how-to-do-a-fast-forward-merge-on-github

This disallows a linear commit history with a delayed stable branch.

Inputs

Input	Description
GITHUB_TOKEN	Automatically provided token, that can be used to authenticate on behalf of the GitHub action, with permissions limited to the repository that contains your workflow
SSH_PRIVATE_KEY	Deploy key for push. Must be set in the repository settings. This is used by the action to push the fast-forwarded branch/commit/PR.

Workflow YML

The Action must be run on triggers to keep the labels up-to-date and run the fast-forward on command.

name: Fast-Forward

  issue_comment:
