Trello Card & GitHub PR Integration

This GitHub action integrates GitHub and Trello, automatically updating Trello cards with pull request information to minimize redundant manual work.

The action looks for:

• Trello card URLs from PR description, comments and commit messages,
• Trello card short ID from PR branch name,

and:

• links a PR to a Trello card and vice versa,
• moves a Trello card when PR is opened, moved back to draft or closed,
• adds a label to a Trello card based on the branch name (e.g. feature/foo),
• assigns a PR author and fellow contributors to a Trello card,
• and more...

Linking Trello cards with GitHub PR

1. github-include-pr-comments

Scans PR comments to find Trello card URLs.

NB! Make sure you set pull-requests: write permission for the job. Learn more.

Default: false

4. github-allow-multiple-cards-in-pr-branch-name

Allows to reference multiple card short IDs in the branch name (e.g. feature/38-39-40-foo-bar).

NB! Option github-include-pr-branch-name needs to be true and it is recommended to set trello-board-id to avoid moving wrong cards.

Default: false

5. github-include-new-card-command

Creates a new Trello card from PR details if "/new-trello-card" is written in the PR description. Replaces "/new-trello-card" with the card link.

Throws an error if no Trello card can be found in the PR.

Default: false

    GithubUser1:TrelloUser1
    GithubUser2:TrelloUser2

Default: true

3. trello-switch-members-in-review

Replaces Trello card members with PR reviewers when PR is opened. It reassigns the PR author, contributors and assignees when the card is moved away from trello-list-id-pr-open.

Default: false

4. trello-remove-unrelated-members

Removes card members who are not authors, contributors or assignees of the PR.

Default: true

5. trello-organization-name
