About RuSTy

RuSTy is a structured text (ST) compiler written in Rust and based on the LLVM compiler backend. We use the logos crate library to perform lexical analysis before the custom parser runs. RuSTy puts out static or shared objects as well as LLVM IR or bitcode by the flip of a command line flag. We are aiming towards an open-source industry-grade ST compiler supporting at least the features in 2nd edition IEC 61131 standard.

Getting started

Start by installing Rust and git on your machine. Then, clone this repository and run cargo build to compile the code. Check out the documentation for further reference.
