I would like to present to you an open-source competitive programming (primarily codeforces) discord bot written in python by meooow, algmyr, Narut, Rahul, pajenegod, aryaman, DeliciousFlatChest, Chilli, c1729, cfalas and mblazev. Source code is avaliable on github. If you would like to try the bot without having to set it up yourself, enter this server: discord.gg/2CJ6qvY. The bot is still work in progress, but it is already 4 months old so it can already do quite a few cool things. Here is a showcase of a subset of its features:
- It can plot rating distribution of either active or all codeforces users, in either normal or log scale, who have competed at least n times. For example,
;plot cfdistrib normal active 5gives:
- It can also place a provided list of users on a plot of the percentile distribution of codeforces. For example,
;plot centile mblazev laggy heon +zoom
- If you're curious how the entire percentile distribution looks like
;plot centile
- It can plot codeforces rating graphs for multiple users. For example,
;plot rating mblazev heon tomx +zoom
- It can plot a histogram of problems solved by a user, color-coded by submission type. For example,
;plot solved stefdasca
- Of course, it works for multiple users as well. For example
;plot solved stefdasca pikmike
- It can even plot codeforces rating overlaid on a scatter plot of problems solved along with a running average of ratings of problems solved in practice! For example
;plot scatter pikmike
- And of course, it can also plot the rating distribution of server members.
;plot distrib
3 other plotting commands are still WIP so I will not showcase them yet. Some non-graph features include:
It also has a set of commands which we refer to as "gitgud". They are ;gitgud, ;gotgud, ;nogud, ;gudgitters and ;upsolve. They incentivize solving problems around user's rating by giving points (depending on relative difficulty) and maintaining a scoreboard. In this example, a 1900 rated user requested a 100 rating higher problem (worth 12 points):
To report a solved problem, you run ;gotgud.
To skip a problem (after at least 3 hours), you run ;nogud.
Apart from random problems, you can also gain points for ;upsolve-ing problems you failed in a contest. For example:
To display the scoreboard, run ;gudgitters
It has even more features (many of which are WIP), but I've omitted them for sake of brevity. We are also planning new features and we welcome new contributors; we'd be happy to help you find your way around the codebase. It's moderately big (3.2k lines of code, not counting comments and whitespaces) but stringent code review ensures the code remains non-terrible.
If you've come this far, just enter discord.gg/2CJ6qvY and try it out! Make sure to read ;help for more details.
Nice
... We can see what you typed before editing......
great bot :D
Wow the bot looks amazing! Can't wait to try it out :)
I joined the server and the people there are really friendly. The bot's features are also very useful too.
It's sad that horse has to be like that.
Yeah, that horse is acting like a piece of crap. Other people there are friendly.
Horse being the savage he is is one of the first reasons we still did not die. He is doing a great work.
Yeah no doubt abt that! He is really good at what he does clearly but he's being arrogant and I think he knows that. Well, people there have told him that and he's taken that into account. Anyway, this bot is fun and really useful!
Indeed, where would we be without Horse's divine providence? /s
Good Stuff
Have you considered implementing something similar to CF Predictor or perhaps even borrowing some of the public CF Predictor API to enhance the bot?
I would be very interested in working on what could be the greatest CF crossover to date. :)
The bot does rating prediction. Read the whole post :P
Sorry, I should have been more specific! I meant that it would be nice to see what your rating change would have been during a virtual participation as well, in addition to the live participations currently supported.
Oh you can pitch that idea to #suggestions and it will be put on list. Though there are currently 32 issues and 6 pull requests outstanding so you might have to wait a while.
Bot is amazing, great work :D
the best thing to happen to codeforces since the invention of codeforces
i think you have forgotten to put kkbb in the credits list, mblazev
I wish I could've contributed to this amazing bot!
rip link isnt working
upd: working now
justicefornumb
For you I am Mr master
justiceforbaumanec
It's because you are on ban list. I'm sorry.
why
Codeforces handle for @handle not found in databaseshows for green even i set my handle cp community discord ?? is it a bug ? UPD : got that.Thanks for crediting my two commits
Well remember if you didn't write that I would have done a polyfit() in
;chillilmaoorz polyfit = big brain
Good bot!
I'm pretty sure this bot will help CP become more fun as a sport.
why discord link is not working?
It's working unless you're banned.
the link is not working :(
This bot's just amazing and I seriously want to have it in one of my servers, but I can't cuz I have some weird issue with my PATH and Python and Poetry can't work.... So when would the bot be on https://top.gg ?
Same .. poetry pycairo issues
The pycairo stuff requires you to install some libraries. Recently we updated the README to better describe the setup and dependencies needed. So if you use some recent ubuntu version it should be fairly easy to get it going.
Be aware that we pretty much assume you're on a linux machine, I don't think we have tested how feasible it is to get it running on windows since we added the cairo dependencies. It should be possible, but might be hard.
This is just brilliant. How come I get to know only 9 months later?:(
It is even more brilliant than you think. In those 9 months we added so many more features that the ones mentioned in this archaic blog barely scratch the surface.
How does the problem recommender work i.e. on what basis do you recommend problems to a user?
I'm too lazy to explain the details but for most part it's just random. There are plans to make it smarter using ML but it's not easy.
What a nice thingy.
Because of the new formula causing some problems to become unreasonable for their labeled rating right now, could you allow for skips in
;gitgudMaybe a phone app one day? Or a chrome extension? Cuz if TLE will never be on top.gg that would be sad to have all this functionality limited to one Discord server...
It is not limited to one discord server. It is open source and many servers use it.
Yes but it's not intuitive to add it. Not everybody can, if you're not Linux or you don't use Discord, you won't be able to use it.
Well duh its a discord bot.
Yeah, that's what I mean : It's only a Discord bot. With all the functionality it have, I think it could be something bigger than just a Discord bot, like a phone app.
(Sorry for eventuals english mistakes)
"Porting" this to a mobile platform would essentially mean rewriting the entire thing. The effort required is enormous and the benefit is minimal.
Does the bot automatically update my rating if the rating changes?
If by that you mean role updates then yes.
so the moderator needs to give roleupdate command. And then everyone's rating will get updated.? p.s. sorry for the vague question
You dont need manual intervention for role updates. It happens as soon as mike updates roles on codeforces. Although you can also manually run a command to update roles. You can do
;help roleupdateon your private server to know how to setup auto role updates. Make sure you have Admin/Moderator roleWhen plotting histogram of problems solved by multiple users, 2 consecutive difficulties get merged, e.g. here pikmike's 2400 and 2500 solved have been merged (separately: here).
Is it possible to avoid this merging?
hello, sorry the bot it's simply amazing, but i need some help with the installation on a mac, if someone can help me I will really appreciates that, sorry for the problems and thanks in advance
Is anyone able to deploy this on heroku?
I'm trying but there are some issues with poetry as heroku doesn't have poetry buildpack by default
Hello mblazev
when i try to run this command :
export BOT_TOKEN="XXXXXXXXXXXXXXXXXXXXXXXX.XXXXXX.XXXXXXXXXXXXXXXXXXXXXXXXXXX" poetry run python -m tle
I get this error : — bash: export: `-m': not a valid identifier
Please help me fix this.
Those are supposed to be two different commands... Just copy paste from the README...
Thanks for that. I tried what you suggested. However, it still says, "no module named TLE" what to do?
P.S. Thanks a lot for your help.
Follow the instructions described in the README.

Make sure to cool up your system 24/7 :`)
Can't we use it for another server?
You will have to host your own instance. Code is open source. Thats the only way out.
I have hosted it on my system, and it's working fine! (as long as my Laptop is running) But I wanted to ask, is there any other way to host the bot (maybe in some online server or something) so that when I close my laptop, it still works? it's kind of impossible for me to leave my laptop turned on 24/7!
did you solve it?
I am getting this error please help me fix this!

ERROR:root:Token required
Looks like you probably skipped the step where you put your bot token in the environment file. I would start over and follow every step carefully if I were you. I recently followed the docs exactly and didn't have an issue.
export BOT_TOKEN="Nzk2MzYxNDY4NDEyMTY2MTQ1.X_WzaQ.1x1COGsxVk5vb8wSGyFGMh9Rb08"
export LOGGING_COG_CHANNEL_ID="790954918612697091"
export ALLOW_DUEL_SELF_REGISTER="false"
I have set it like this.
Anyways thank you!!
Please share your credit card no and CVV no along with this BOT_TOKEN. Thanks.
I am also getting the same problem
ERROR:root:Token requiredMy bot token, channel id , everything is correct. Still I am getting this error. What should I do????
Hello aryanc403, what could i do with this?
When I do ./run.sh then it works but after some time it stops working and goes offline. How to solve this ?
Such an amazing bot ;_;
how can i register in duel list??
ask to a mod
How do we update the ratings of handle so it will synced to user's latest rating?
;roleupdate now
;roleupdate now
for 1 time only, and
;roleupdate auto on
for auto roleupdates
Thanks!

Do it work now ?
Thank you for creating this!
