Let me introduce one small program I wrote some time ago, which might be of utility to the members of this community-

Barebones Programming Contest Judge · GitHub

Requirements: It can run on any Unix based system (OSX/Linux etc.)

Initially, it started as a small script to run my C++ program on test data from USACO Contests, INOI, ZCO and IARCS Judges. Old INOI and ZCO problems are not on Codechef and it is thus a pain to check the validity of your solution. Later, I extended it to interpreted languages and added a logging option.

Usage:

It is a command line program with the arguments

judge <interpreter> <program> <testdata directory> (--log)

For compiled languages use the interpreter argument as exec. For example,

judge exec compiled_code test_data

For using something like python,

judge python code.py test_data

Or Java

judge java class_file_name test_data

Hope you find it useful !
