RuSTy PLC Compiler 0.2

This is a preview of the current state of RuSTy.

While the project is still in very active development, we believe that it could be used for most scenarios.

Features

• Support for most common features of the IEC61131-3 ST definition
  • Standard (non object oriented languages) language features
  • Standard functions and Datatypes
  • Variable Length Arrays
  • Classes/Methods (Object Oriented) - Still a proof of concept
• Support for Debugging ST code
• Support for multiple target compilation
• Support for build scripts/ project management

What's coming

Upcoming features include CFC/FBD support, full object oriented support, and parallel compilation.
