When my friends and I were practicing for competitive programming contests we used Arugo quite a bit, and it was a lot of fun. After some time it stopped being hosted (I rehosted it here and it seems to work though). So I decided to write a Discord bot with similar functionality: my hope is that it makes it more convenient and fun to practice with others. Credit (and thanks!) to phattd15/polarity-ac for the original idea!
The following commands are available to you:
-
=challenge [problem (i.e. 1000A)] [length in minutes (40/60/80)] [participants other than you (i.e. @eggag32 @eggag33)]
Starts a challenge.
-
=rating [optional username (i.e. @eggag32)]
Shows your (or other user's) rating graph.
-
=history [optional username (i.e. @eggag32)] [optional page number, 1 by default]
Shows a page of your (or someone else's) challenge history.
-
=leaderboard [optional page number, 1 by default]
Shows a page of the server leaderboard.
-
=register [handle]
Links your CF account.
-
=unlink
Unlinks your CF account and erases all progress.
-
=suggest [rating] [users to suggest for other than you (i.e. @eggag32 @eggag33)]]
Gives some problems at a given rating that none of the users have done.
-
=help
Prints the help message.
To invite the instance I am hosting, use this link.
If you want to host it yourself, you need to make sure you install everything from requirements.txt, add a token.txt file that contains your Discord bot token, add a proxies.json file with the proxies (or change proxy.py to not use them), and run main.py.
