Judge0 API integration for running/judging code with different languages

setInput('judge0') ->setExpectedOutput('the value you entered is : judge0') ->setTimeLimit(1) // seconds ->setMemoryLimitInMegabytes(256) ->submit(); ">

use Mouadbnl\Judge0\Models\Submission;

$submission = Submission::create([
        'language_id' => 54, // C++ (GCC 9.2.0)
        'source_code' =>'
        #include
   
        #include
   
        using namespace std;

        int main(){
            string s;
            cin >> s;
            cout << "the value you entered is : " << s;
            return 0;
        }
        '
    ])
    ->setInput('judge0')
    ->setExpectedOutput('the value you entered is : judge0')
    ->setTimeLimit(1) // seconds
    ->setMemoryLimitInMegabytes(256)
    ->submit();

Installation

You can install the package via composer:

composer require mouadbnl/laravel-judge0

You can publish and run the migrations with:

php artisan vendor:publish --provider="Mouadbnl\Judge0\Judge0ServiceProvider" --tag="judge0-migrations"
php artisan migrate

You can publish the config file with:

php artisan vendor:publish --provider="Mouadbnl\Judge0\Judge0ServiceProvider" --tag="judge0-config"

Usage

First add Submitter trait to the User Model.

use Mouadbnl\Judge0\Traits\Submitter;
class User extends Authenticatable
{
    use Submitter;
    /** **/
}

This create a polymorphique relationship between the User model and the Submission model provided by this package. You can let the User make a submission using the follwing code:

setInput('judge0') ->setExpectedOutput('the value you entered is : judge0') ->setTimeLimit(1) // seconds ->setMemoryLimitInMegabytes(256) ->submit(); ">

$user = User::firstOrFail();
$user->submissions()->create([
        'language_id' => 54, // C++ (GCC 9.2.0)
        'source_code' =>'
        #include
   
        #include
   
        using namespace std;

        int main(){
            string s;
            cin >> s;
            cout << "the value you entered is : " << s;
            return 0;
        }
        '
    ])
    ->setInput('judge0')
    ->setExpectedOutput('the value you entered is : judge0')
    ->setTimeLimit(1) // seconds
    ->setMemoryLimitInMegabytes(256)
    ->submit();
