Competitive Programming Helper Extension for VS Code
By d-agrawal, history, 9 months 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.

It does not work well if you have a vim extension like VSCodeVim.

The <esc> key doesn't work when you try to change insert to normal mode if I enable your extension. :/

Thanks for such a great tool.

Unfortunately Im still not able to run it in Windows10: the button "Run Testcases" does nothing after pressing it.

I want to use g++ compiler from WSL to avoid install MinGW. Is there a way to configure this as the default option?

    Thanks for using it!

    Hmm, I currently don't support changing compiler itself, so you won't be able to use g++ from WSL! :-(

    A bad solution would be to create a global alias for g++ that points to 'wsl g++' but it's not convenient!

    What's the problem with using MinGW or CYGWIN? It takes only a few minutes to install g++ :-)

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

Do you know how we can change it, so it compiles with c++11 or c++14. I am getting a compilation error if I use the syntax for (int i : arr).

    Yes, you can add any flags you want from Settings. A GIF shows this in the github link above.

    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

        As of now, it doesn't. For example, you could try this problem A. Common Prefixes. An AC soln gives "Failed" when using the tool because mine doesn't match with the testcase o/p. So d-agrawal, if possible, please try adding this feature. Will make the extension even better. Apart from that, it's really cool. Thanks!

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

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?
