rosterbot

"I have to ban you from writing slack bots" - @rokane

• A slack app for rostering

Use

• Roster a message every day at 23:00 UTC

/roster add "0 23 * * *" "message" @user1, @user2, @user3 
// 23:00 UTC: message @user1
// 23:00 Tomorrow: message @user2
// 23:00 The day after tomorrow: message @user2

• Remove rosters for current channel

/roster remove

Caveats

• Doesn't support full cron syntax:

* * * * * is supported
0 /10 * * is not supported

• All time must be specified in UTC time, not local time

About

• Hosted on google cloud functions
• Firestore to store data (webhooks and subscriptions)
• Uses google cloud scheduling to execute every minute (* * * * *) in order to filter out firestore subscriptions for that time
