THIS PLUGIN IS STILL UNDER DEVELOPMENT AND NOT SUTIABLE FOR PRODUCTION SITES

Introduction

The Online Judge 2 plugin for Moodle 2 is designed for courses involving programming. It can automatically grade submitted source code by testing them against customizable test cases (ACM-ICPC/Online Judge style).

It contains:

1. A local plugin call judgelib which provides the essential abilities of online judge. It works like a library.
2. A assignment type plugin call online judge which provides a UI to teachers and students and calls the judgelib to judge submissions.

There are two judge engines:

1. Sandbox compiles and executes programs on the server in a protected environment. Supports C and C++ only.
2. Ideone posts all data to ideone.com which compiles and executes programs remotely. Supports 40+ languaes, such as C/C++, Java, Python, C#, JavaScript, Perl, PHP.

The workflow is:

1. Administrators set global settings in judgelib.
2. Teachers create Online Judge Assignment Activities and setup testcases etc.
3. Students submit code in Online Judge Assignment Activities.
4. A judge daemon judges the submissions in backgroud.
5. Teachers and students get judge results in Online Judge Assignment Activities.
