CC Virtual Machine

CC Virtual Machine

This repository contains the sourcecode for the CC Virtual Machine (CCVM). CCVM is a bytecode interpreter (similar to JVM for java) created by Luc de Wit meant to be used as a runtime for non-serious programming languages.

Road-Map

In the future there are plans for extending the functionality of the CCVM and usages of the CC Virtual Machine.

• Get Hello World running on CCVM
• Get fibonacci running on CCVM
• Render a mandelbrot on CCVM
• Creating an assembly language ontop of CCVM (CCA)
• Creating a stack based language ontop of CCA
• Creating a lisp like language ontop of CCA
• Creating a procedural BASIC-like language ontop of CCA
• Creating a C-like language ontop of CCA
• Online CCVM/CCA interpreter using web assembly
