ContestWatcher on Telegram
By yancouto, history, 8 years ago, In English

Hey!

Me and a couple of friends (victorsenam, gabrielrc) developed a telegram bot to list upcoming contests. The bot lists the main contests from Codeforces, Topcoder, Codechef, CSAcademy and AtCoder!

Checkout the bot here!

You can use /upcoming to list upcoming contests, and the bot will also remind you 1 day and 1 hour before each contest (this can be enabled and disabled using /start and /stop)

NEW!

Now you can add you Codeforces handles and get notifications for rating changes in CF rounds. Use /help_handles to get info on how to add handles.

The code is available on GitHub. Send us your pull requests!

Any comments and bug-reports are appreciated :)

    ClistBot can't be added in groups :( But we can add ContestWatcherBot to groups too :D

Your bot is my favorite :) (I've tried like 3 or 4). Atcoder integration would be cool :)

Great work! :)

    This is just my opinion, but what I like the most about this bot is that it watches over sites that hold contests with similar format. HackerRank is great but it has a lot of different kind of contests. If they start adding all kind of sites to their bot they'll end with something like ClistBot, which, again, is great but doesn't fit you if you're only interested in this kind of contest(codeforces, topcoder, ...).

    Again, this is just my opinion :)

      But similarly, CodeChef has many types of contests, too.

      It would be ok since you can select the online judges you wish to be updated about. If you didn't care for hackerrank you could disable it.

    Yes, this happens when rounds are extended. The system testing warnings will work normally, though.

      Have you ever considered adding a functionality that would allow me to tell the bot my CF handle and then the bot could send the rating changes individually?

I feel that it would be good to append the CSAcademy name in front of their contests rather than just showing round number #xx. That got me confused.

Right now it isn't showing codeforces rounds div 1 and div 2 423(based on VK cup finals) in upcoming contests list. It would be great if you fix this bug(and some others like this)

    It is still not showing on /upcoming.

    I tried /enable csacademy but bot respond "You are not ignoring this judge." which means the setting are not the issue.
