Battle notifications

Battle Notifier

Bump for BN bot :D

New improvements and features

New useful features for Battle Notifier:

• Edit settings via web.
• Add queue notifications.
• Migrate user configs to database, instead of current storage under bn/ folder with .json files.
• Bonus: how to notify pipes?

Edit settings via web

Now that there is Discord login, we could make battle notification configurations much more usable via elma.online instead of using Discord complex commands :) Plus it would add a lot more visibility to this feature.

We can keep Discord commands too, specially !bn help and !bn on/off, and redirect to the elma.online to set your configuration.

Add queue notifications

Barryp asked to have 5 minutes heads up for his battles, but I dunno how viable this is. My idea is to have queue notifications, we already have queue events logged at Discord. Would need to define what is an useful message. This is a queue log example:

:elmapple: Queue: 26 mins apple by Chris

This alone might not very useful. It would be nice to include the whole queue plus an estimation of how long it will take to start. The estimation would be always approximated because battles can be aborted/stopped, and for example One Life battles can certainly last less than queued (although users know this already).

There could be update notifications too, for when the queue changes. For example, if I'm subscribed to Chris, I get notified when:

• Chris queues a battle.
• Chris aborts his battle from the queue
• Another battle ends or is aborted/stopped and Chris' battle moves up 1 place.
• And of course if Chris' battle starts.

Could also add a setting to turn off queue notifications, but keeping start notifications on and vice versa.

Bonus: how to notify pipes?

A few ideas of how this could be done:

Group of level name patterns

Add level name patterns to #group-name, example with commands:
!bn add #pipe APipe JoPi Pipo Popi

Remove a specific level name pattern from the group:
!bn remove #pipe APipe

Then subscribe the group:
Normal #pipe by Pab

This would work for pipes and other things.
Concerns: Let anyone edit #pipe or the first on to make this group owns it?

Recognize pipes algorithmically

Recognize if it's a pipe via code :D
