Slack Queue App

A Slack bot to maintain a set of per-channel queues (e.g., for tutoring, help desk, etc.).

About

The bot supports four commands/actions:

Creating or deleting a per-channel queue.
- This operation is restricted to global administrators.
- Channel queues can be created with an optional admin channel that will
  receive notifications about queue state.
- If a queue has an admin channel, only users in that channel may dequeue or
  remove users from the queue.
In a channel, users can enqueue themselves via a slash (/) command. Any text
after the command is stored as metadata.
The queue state can be listed by admins using a list slash command.
- In the UI response, users can be dequeued, removed, or moved up/down the
  queue.
Admins may also dequeue the first user in the queue via another slash command.

If an optional persistence flag is supplied, application state and queue state
is persisted across restarts.
