SharIF Judge

SharIF Judge is a free and open source online judge for C, C++, Java and Python programming courses. SharIF Judge is a fork of the original Sharif Judge beautifully created by @mjnaderi. This forked version contain many improvements, mostly due to the needs by our faculty at @ifunpar.

The web interface is written in PHP (CodeIgniter framework) and the main backend is written in BASH.

Python in SharIF Judge is not sandboxed yet. Just a low level of security is provided for python. If you want to use SharIF Judge for python, USE IT AT YOUR OWN RISK or provide sandboxing yourself.

Branches, Tags and Releases

The numbering may be confusing, I apologize. However, here are some explanations:

• Branches, sorted from newest to oldest:
  • Version-1 this is the main branch, since mjnaderi is using this naming for the main branch.
  • Version-1.5, this is an older branch, containing action replay and (supposedly) PHP 8.3 compatibility
  • Version-1.1, this is an even older branch, compatible up to PHP 7.4, but pretty stable
  • docs, documentation branch, similar to mjnaderi's one but maybe with some adjustments
  • Other branches are undocumented
• Tags and releases, sorted from newest to oldest
  • v1.5.x-ifunpar release of Version-1.5 branch
  • v1.4.x-ifunpar release of pre-Version-1.1 branch. Named 1.4 because mjnaderi used that. We will no longer use mjnaderi's one.

For running SharIF Judge, a Linux server with following requirements is needed:

• Webserver running PHP version 5.3 or later with mysqli extension
