Catalyst — Accelerates Competitive Coding on Codeforces
By Rudresh, 5 days ago, In English

CodeForces is an awesome platform for competitive programming, when I started practicing on CodeForces, the only thing I felt missing was the inbuild IDE for solving problems.

I thought It'd be a fun project to do, so during this vacation, I developed a VS code extension named Catalyst for that.

Catalyst automatically fetches the problem and displays it, parses test cases, runs and evaluates your code on test cases. You can edit/add/remove test cases as you like, and when you are done, it can submit your code and then track the submission in real-time. All this in Vs code.

If you have any suggestions or issues regarding Catalyst please let me know

Here's a little demo of it — https://raw.githubusercontent.com/RudreshVeerkhare/Catalyst/main/readme/CatalystQuickStart.mp4

    Can you give some details on error...

    Note — You don't need to give public class name same as filename if you are using catalyst

Wow. I have watched the video and this is really cool. Well done. Can this be used in live contests and if so, does it parse entire problem sets? Instead of parsing per problem.

    Thanks... :)
    Yes this can be used in live contests..
    But fetching all problems at once is not possible currently.. Actually I'm working on it...

    Update — I just added the feature to fetch Entire contest in version 0.0.7
    now you can either put Contest URL or Problem URL and Catalyst will automatically fetch all problem if it's a Contest url..
    Please let me know if you fetch any issues while using this feature..
    Thanks..

      I see. This is still great, at least while the other features are in progress. Cheers.

can you use https://github.com/jmerle/competitive-companion for parsing, i have the chrome extension of it, which parses question by just click of a button and saves the task of copy pasting the urls.

also add the support of mirror website codeforces.ml

Also c++ submission within vscode does not show option for g++ 17 9.2.0 64 bit msys 2 which i mostly use.

      So, can you make your own chrome extension, which parses problem statement too? Or can you just tweak the existing open source competitive-companion extension to do this?

    Firstly, Catalyst uses AES-256-CBC for encryption of Login Credentials..
    then these Encrypted Credentials are stored in the system's keychain...
    On macOS the encrypted passwords are managed by the Keychain, on Linux they are managed by the Secret Service API/libsecret, and on Windows they are managed by Credential Vault...
    And keys for encryption are updated every time Credentials are updated..
    Hope this will help..
