Import your vJudge solutions to actual online judges. Currently supports UVa, CodeForces, SPOJ, and CodeForces GYM.

vjudge-to-oj

Competitive programmers spend hundreds and thousands of hours practicing programming problems and participating contests. Vjudge has been an amazing platform for participating/hosting programming contests and problem-solving.

However, there can be scenarios where you'd like to add vjudge solutions to the actual judge profiles specifically. I personally felt the need of it along with some of my friends and colleagues. It's a tiresome job to submit all the solved problems of vjudge to the actual judges. This here is a small approach to get such works done easily.

Current solution will only work for UVa, CodeForces, LightOj and SPOJ. So far, it's pretty much stable and working just fine. It's roughly written and tested. But hey, it works!!!

With enough response and your contribution I hope to add some more judges here as well. Huge thanks to all who contributed so far to my fun projects.

Let me know if you have any questions/suggestions/feedbacks or simply if you liked it.

Hope you enjoy. <3

Installation Guide:

With poetry(Easier):-

1. Download/clone the repository from github using git:-
   • Run git clone https://github.com/m-s-abeer/vjudge-to-oj.git from your cmd/terminal in your specified directory.
2. Download and install python ^3.10 from here:- https://www.python.org/downloads/
3. Make sure you are using the desired python version by running python --version
4. Download and install python-poetry
   • Linux, MacOS, WSL:- https://python-poetry.org/docs/#installing-with-the-official-installer
   • Windows(powershell):- (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
   • If none of the above worked or to know more:- https://python-poetry.org/docs/#installing-with-the-official-installer
5. Get inside project vjudge-to-oj and then write poetry install on cmd/terminal. This should install all the dependencies/packages.

Without poetry:-

1. Download/clone the repository from github using git:-
   • Run git clone https://github.com/m-s-abeer/vjudge-to-oj.git from your cmd/terminal in your specified directory.
2. Download and install python ^3.10 from here:- https://www.python.org/downloads/
3. Make sure you are using the desired python version by running python --version
4. Get inside project vjudge-to-oj
5. Write python -m venv .venv to create a python environment inside project.
6. Write source ./.venv/activate for Linux, MacOS, WSL. For windows write .\.venv\Scripts\activate to activate the python environment
7. Run pip install --upgrade pip and then pip install -r requirements.txt to install all the dependencies/packages

Set your .env file:-

1. Create a file named .env in the project directory.
2. Copy the contents of .env.example and paste it in .env file.
3. Read the comments in .env file and set the values accordingly.

How it should work:

1. Complete the #installation-guide and run the following command inside project root from cmd/terminal to activate the environment:-
   • Poetry users: poetry shell
   • Linux, MacOS, WSL users: source ./.venv/bin/activate
   • Windows users: .\.venv\Scripts\activate
2. Make sure you have set the values in .env file correctly.
3. Run python main.py from the project root
4. The program will automatically download your Accepted solutions from vjudge and then submit them one by one and store the submitted solutions to another folder(modules>Submitted>UVA>).
5. It'll show you the status report as it runs. It may look messy, but it actually helps you see what's going on.

• No login data is bypassed/redirected to anywhere else. Vjudge login data is stored inside "vjudge-to-oj>modules>cookies" this directory. You can empty that folder if you're concerned or have issues logging in.

N.B: Please don't run it when the corresponding judge is already busy and many submissions are already in queue. It's built only for personal uses. This program is in no way meant to hamper the solving environment of a judging platform.

vjudge-to-oj's Issues

Vjudge sometimes time-outs when requesting for solution export

Vjudge sometimes timeouts when downloading the solutions from .

The program stops unexpectedly when it can't find the downloaded zip.

'PyQt6.QtWebEngineCore' issue

I'm facing this issue
And where should I create the .env file can you be more specific?

Use .env for credential inputs instead of main.py

In the current solution, we're updating main.py directly to insert raw credentials. Not good! It requires you to clean it up before taking the latest pull and the credentials shouldn't be put into an actual source code file.

The next approach is going to be:-

1. There will be an env.example file containing credential format and if the profile will be used actively for the next run.
2. The user will copy the env.example to .env file and insert their credentials there.
3. Running the main function will use .env to determine which profiles to use and collect credentials from .env for submission.

This can also be improved in the future, depending on the demand. Leave a comment if you think we should take a different path.

thought that was the extensionID error.

Vjudge login issue

I ran with & without editing the .env file with VJ usr & pass but still getting this:

The system cannot find the path specified: '\\modules\\solutions\\Gym'

When running main.py, it shown an error FileNotFoundError: [WinError 3] that says "The system cannot find the path in modules\solutions\Gym and there is no folder generated named Gym.
