Catalyst — Accelerates Competitive Coding on Codeforces

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.

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

• 16 months ago, # ^ | You are Welcome sandipan_2224.. :) Please let me know in case of any issues..

• 16 months ago, # ^ | Thanks sid_rasa :)

• 16 months ago, # ^ | ← Rev. 3 →   0 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

  • 16 months ago, # ^ | Ok, now I can compile and submit. Thanks for clarifying.

• 16 months ago, # ^ | It's specially designed for codeforces only..

• 16 months ago, # ^ | Yes.. It's a nice idea.. I'll add this feature... Thanks..

  • 16 months ago, # ^ | The pleasure is all mine.

• 16 months ago, # ^ | ← Rev. 3 →   0 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 face any issues while using this feature.. Thanks..

  • 16 months ago, # ^ | I see. This is still great, at least while the other features are in progress. Cheers.

  • 15 months ago, # ^ | I just added Catalyst to my VS-Code and wanted to congratulate you for this splendid work. Really a lot of thanks for working on this. Also, I have a query regarding contest fetching. When I am giving the contest URL it is just fetching the first question. How can I slide to the next question or any other question?? Thanks in advance

    • 15 months ago, # ^ | Thanks you very much... I'm really happy that you liked it... And regarding contest fetching... It'll fetch all problems, and will open the first one.. You can switch problems easily through file explorer menu in the vscode.. Just select source code file named with problem.. Catalyst will automatically open that problem statement for you on the right side...

      • 15 months ago, # ^ | Thanks for the help.

• 16 months ago, # ^ | I'm really sorry that you don't like it.. :(

• 16 months ago, # ^ | I could've used competitive-companion for parsing but I wanted problem text data also... And thanks for this suggestions.. I'll try to add support to mirror site also... and I just added the option g++ 17 9.2.0 64 bit msys 2 for submition...

  • 16 months ago, # ^ | 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?

    • 16 months ago, # ^ | As of now I don't know how to make crome extension.. But I'll surely try this...

• 16 months ago, # ^ | Yes..you can change handle by using command "Update Login Details"... to execute the command press Ctrl+Shift+P and enter Update Login Details..

  • 9 months ago, # ^ | ← Rev. 2 →   0 Great Work!!

    • 9 months ago, # ^ | Thanks.. :)

• 16 months ago, # ^ | Thanks.. :)

• 16 months ago, # ^ | ← Rev. 2 →   0 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..

• 15 months ago, # ^ | It's doesn't login everytime... It stores cookies... And when cookies expires.. It login again....

• 15 months ago, # ^ | You can load all problems from contest by giving contest URL instead of problem URL...

  • 15 months ago, # ^ | ← Rev. 3 →   0 But even when I give contest URL only one tab with problem A opens up.

    • 15 months ago, # ^ | Oh. For that... You can simply open multiple problem from left side file view... Or you could drag them to editor... That will open multiple files... And then you can switch between them easily... Hope it helps..

• 15 months ago, # ^ | You can add your template by assigning default template from settings...

• 15 months ago, # ^ | ← Rev. 2 →   0 Nvm, thanks for the extension.

• 14 months ago, # ^ | ← Rev. 2 →   0 Not till now... But I'll add option in settings for that... UPDATE — Added an option in settings to hide editorial button in version 1.2.1..

  • 14 months ago, # ^ | Thank you so much for helping! Amazing Extension.

• 13 months ago, # ^ | ← Rev. 2 →   +3 There's a feature to set base template for problem statement.. You can access it through extension settings..

  • 13 months ago, # ^ | Got it. Thank you for helping.

• 13 months ago, # ^ | ← Rev. 2 →   0 Yes...you could add args for compilation.. From extension settings...

  • 13 months ago, # ^ | Cool, works. Thank you.

• 13 months ago, # ^ | Yes it shows no problem page error

• 13 months ago, # ^ | Sorry for this... It seems that Codeforces have made an small change... I'll fix this soon... And thanks for reporting this issue..

• 13 months ago, # ^ | ← Rev. 2 →   0 Today I tried debugging the Catalyst... And it was working already... I think Codeforces have reverted the change of RCPC cookie... Let me know if it's working for you or not...

  • 13 months ago, # ^ | It works for me now! Thanks for trying.

• 13 months ago, # ^ | There's a command in command pallet... Update login details..

• 12 months ago, # ^ | Thanks..:)

• 11 months ago, # ^ | ← Rev. 2 →   0 Sorry for this.... This is a bug due to contest questions are being added to new folder... Currently my exams are going on... I'll fix it ASAP after that... Quickfix for this problem is that.... Bring your sourcecode out of the contest folder and it'll work... Hope it helps..

  • 11 months ago, # ^ | ya ya thats what i meant. Np you give your exams. BEST OF LUCK. :)

    • 11 months ago, # ^ | I checked it... Problem was that... Initially contest problem source codes were stored in root of workspace... But it was getting quite messy given that there might be other problem source codes which would make it difficult to identify contest problems from individuals... To solve this issue, I added a feature to group all contest problems in a folder in the workspace root... I have modified some internal data elements of problem cache file in this process... So solution to that is simply update Catalyst to latest version and reload that contest... and don't worry, reloading contest won't override your solutions for those contest questions... Let me know if it solved the problem or not... :)

      • 11 months ago, # ^ | Thanks Man. :) It worked. U r a Genius.

• 10 months ago, # ^ | Thanks for the suggestion.. But it's specifically designed for CodeForces only... Making it for other platforms will require whole new implementation... This is something which I've put in future scope..

• 10 months ago, # ^ | That's a really good idea.. But thing is that VScode is made using electron which make it possible to show html content.. But I'm not sure about Sublime text.. I haven't found anything similar in Sublime text yet...

• 9 months ago, # ^ | It should operative.. I'll look into it... Thanks for reporting...

  • 7 months ago, # ^ | Certificate has expired why is it showing this message

    • 7 months ago, # ^ | ← Rev. 2 →   0 Thanks For reporting.. Seems like there has been some changes in requirement... I'll update it ASAP. UPDATE - I've fixed it now.. Let me know if you face any problem.. :)

      • 7 months ago, # ^ | It is fixed now. Thank you very much this is extension is very helpful and amazing

• 7 months ago, # ^ | ← Rev. 2 →   0 I'll try to fix it soon... But it might take little time.. Really sorry for inconvenience... UPDATE - It's fixed now.. Let me know if you face any issue...

• 7 months ago, # ^ | It's fixed now... thanks for reporting.. :)

• 3 months ago, # ^ | you can change handle by using command "Update Login Details"... to execute the command press Ctrl+Shift+P and enter "Update Login Details"..

  • 3 months ago, # ^ | Thanks for your suggestions>0<!

• 5 weeks ago, # ^ | I already found the answer. If you have KDE installed you have to install the gnome-keyring dependency

• 7 hours ago, # ^ | And I cannot get the editorial.
