Supported processors

Read the docs for more information.

Processor	Language(s)*	Required Docker image
Bash	Shell	bash
Clang	C (c) C++ (cpp)	clangbuiltlinux/ubuntu
GCC	C (c) C++ (cpp) Go (go)	gcc
Go	Go	golang
Mono	Visual Basic (vb) C# (csharp)	mono
Node	Node.js	node
OpenJDK	Java	openjdk
PHP	PHP	php
PyPy	Python	pypy
Python	Python	python
Ruby	Ruby	ruby
Swift	Swift	swift

* The language argumnets of the processors which support multiple languages should be provided, or the source will be judged in the default language (usually C++ or C#, emboldened in the table).
