Competitive Programming Helper Extension for VS Code
By d-agrawal, history, 3 years ago, In English

Hello All!

A competitive programming extension for VS Code!

I have created an extension for Visual Studio Code that makes testing, creating, and downloading testcases very easy. It is similar to CPPFastOlympicCoding for Sublime. Search within VS Code Extensions or download from link below. Works on Windows, Mac, Linux. You need to have G++ ( GCC ) installed.

Extension Name : Competitive Programming Helper

Store Link : https://marketplace.visualstudio.com/items?itemName=DivyanshuAgrawal.competitive-programming-helper

Features

  • Add multiple testcases.

  • Download from Codeforces automatically.

  • Auto compile and run, shows compilation errors, run-time errors ( stack overflow, seg-faults etc).

  • GUI, no manual file editing.

UI

Please try it out and give feedback. Please report issues/ send feature requests here : https://github.com/agrawal-d/competitive-programming-helper

Thanks!

I started few months ago similar tool, you can check it here:

I love the way you display testcases in your tool. Unfortunately I don't have too much time to hack on mine this days, but it would be great if I could incorporate this to my tool, are you ok with that? I see you don't have any LICENSE, so I encourage you to add one.

    Your extension is pretty cool! My university examinations are coming soon, so maybe later? And thanks for reminding, I'll add the LICENSE.

Can I suggest some ideas ? (These may slowdown the test so can you do a Advance Mode for advance setting allowed ?)

1) Add some more verdicts instead of Success and Failed
2) Advance Settings for Each Testcase
3) Advance Settings for All Testcases
4) Advance Settings for codes

Hope your project become success and well-known <3

    The firefox extension have never worked for me. It seems like the port just isn't updated when set. As I couldn't find the local settings file to edit it by myself, I ended up never using it... Copy-pasting a test into a local file is just a matter of seconds after all, even if I'd rather have it done automatically :)

Hi, is there a quick howto, simple starter guide? I installed the extension, but there is literaly no button or anything where I can click. How can I download problems/testcases from codeforces?

I am not an expert with VSC. Where to start?

This is an amazing extension. I was wondering if it's possible to open the file with a custom code template while parsing

Does this work on WSL? When running the test cases, it seems the extension is not picking up the output from my program.

      So if the sample input has an alternate answer , it will not work ? I thought codeforces api could help maybe to check output with their custom checker

I am using this extension for quite a while now and I must say, its really useful, Thank you so much. However, I have been facing an issue from the start. When, I am done with my code and click the green button on the input file to show me the answer, for the first time, it runs for about 10 secs before displaying timed out and SIGTERM error. However, once I close vscode and start again, it runs successfully and shows the desired output. Is there any fix?

    Just save your file before running the code for the first time . Press Ctrl + s and then press the green button

        Ctrl+Alt+B

        You can modify this from VS Code.

        Preferences->Keyboard Shortcutes-> Scroll down to "Run Testcases"

        Then you can set it by yours.

Hey, first thanks for this great tool. But I still don't understand how to debug while using this effectively. I mean I generally don't use a debugger. I just use cout statements. So to do this in VS Code I have to do it in the terminal . But the problem is the file name is generally so big. So what should I do?

It's an amazing tool, I have been using it for months now, but today somehow, the CPH judge got attached to the VS-code sidebar, instead of the usual view on the right side, Can you please tell me how to fix it?

Can we set the default code template as well, since currently we are just able to create a file with the name of of the problem and extracting the test cases. But the code area is blank. Can we have some default code as well?? Thanks

    Image to extension settings

    In the mentioned image look for the cursor position where you can add the path of your template.cpp or any other file whose contents you want to display as default when CPH create the files! Hope it helps!

      EDIT — PROBLEM FIXED, READ THE REPLY COMMENT TO THIS COMMENT

      It says no settings found for the extension, and whenever I am creating a new file, it asks for the file language and if I dont press in time, or by mistake press somewhere else, error pops up saying aborted creation of new file. Can you please help?

        TO ANYONE WHO DOES NOT SEE THE EXTENSION SETTINGS AND HAVING PROBLEM OF "ABORTED CREATION OF NEW FILE"

        FOLLOW THE STEPS:

        1. GO TO : C:\Users\USERNAME\vscode\extensions\divyanshuagrawal.competitive-programming-helper-5.8.5

        2. OPEN package.json FILE

        3. LOCATE "cph.general.defaultLanguage"

        4. CHANGE default VALUE TO LANGUAGE OF YOUR CHOICE

SIGTERM int the first test case :

I have been using this tool for sometime now and this is helpful and thank for that , but after every run this gives sigterm for the first test case (even if the answer is correct and can run under 2ms); it gives the time as 2543 ms or something close and when I run the test cases again it is giving test case passed as the output
