Algohub Judge Engine is a modern online judge engine, which supports most of programming languages.

Supported OS: Ubuntu 16.04, CentOS 6.7

./install.sh

mvn clean package

java -jar target/judge-engine-1.0-SNAPSHOT.jar src/test/resources/problems/2-sum/2-sum.json PYTHON src/test/resources/problems/2-sum/solution.py

The judge engine uses compilers and interpreters under the hood, so you need to install compilers and interpreters in advance.

Currently Algohub Judge Engine uses JDK 8, GCC 5, Python3 and Ruby 2.

The following commands should be available in $PATH:

• java
• javac
• g++
• python3
• ruby

Algohub Judge Engine relies on the rapidjson library to support C++ language. So we need to make the rapidjson system wide.

git clone git@github.com:miloyip/rapidjson.git
sudo cp -r rapidjson/include/rapidjson/ /usr/local/include/

First, download the languages support files,

git clone https://github.com/algohub/judge-engine-languages-support.git
cd judge-engine-languages-support/

Algohub Judge Engine has some pre-defined C++ header files which are needed during compilation.

sudo cp -r judge-engine-cpp-support/include/algohub/ /usr/local/include/

The judge engine has a pre-defined python module named algohub, which is need during runtime.

Copy the Python algohub module into one of Python's default module paths, i.e., sys.path

python3 -c "import sys;print(sys.path);"
cd judge-engine-languages-support/
sudo cp -r judge-engine-python-support/algohub/ /usr/local/lib/python3.5/dist-packages/

The judge engine also has a pre-defined ruby module named algohub, which is need during runtime.

Copy the Ruby algohub module into one of Ruby's default module search path(run ruby -e 'puts $:' to get all paths)

cd judge-engine-languages-support/
sudo cp ruby/algohub.rb /usr/local/lib/site_ruby/2.3.0/

Special thanks to @rednaxelafx, who is a compiler expert and gave me a lot of vital technical suggestions, this project would not have been possible without his help.
