Pull Request Review Reminder (Purrr)

Note

This project is currently under construction.

Purrr integrates GitHub and Slack seamlessly, to streamline code reviews and cut down the turnaround time to merge pull requests.

• Real-time, relevant, informative, 2-way updates
• Easier collaboration and faster execution
• Free and open-source

No more:

• Delays due to missed requests, comments, and state changes
• Notification fatigue due to updates that don't concern you
• Questions like "Who's turn is it" or "What should I do now"

All that and more is implemented with a few hundred lines of Python. AutoKitteh takes care of all the system infrastructure and reliability needs.

Slack Usage

Event-based, 2-way synchronization:

• Slack channels are created and archived automatically for each PR
• Stakeholders are added and removed automatically in Slack and GitHub
• Reviews, comments, conversation threads, and emoji reactions are updated in both directions

User matching between GitHub and Slack is based on email addresses and case-insensitive full names.

Available Slack slash commands:

• /purrr help
• /purrr opt-in
• /purrr opt-out
• /purrr list
• /purrr status [PR]
• /purrr approve [PR]

Data Storage

Purrr uses a simple Google Sheet for:

1. Mapping between GitHub PRs and Slack channels
2. Mapping between GitHub comments/reviews and Slack message threads
3. Caching user IDs (optimization to reduce API calls)
4. User opt-out database

Use-cases 1 and 2 use a TTL of 30 days (configurable in the autokitteh.yaml manifest file). Use-case 3 uses a TTL of one day since the last cache hit. Use-case 4 is permanent (until the user opts back in).
