RuSTy Documentation

RuSTy compiles IEC 61131-3 Structured Text into machine code, with LLVM as its back end. The compiler binary is called plc.

This book has two parts. Open the one you need in the sidebar.

• User Documentation: how to install the compiler, how to use it, and how to write Structured Text for it.
• Technical Documentation: how the compiler works inside. The stages of the pipeline, the participants that rewrite the program between the stages, the other outputs, and the internals of each language construct.
