A C# COMPILER FOR BARE METAL

RubyC — C#-Style Language, Compiled Straight to Native Bare Metal

RubyC is an independent C# compiler built from first principles. Write familiar C#-style code — classes, interfaces, namespaces — and compile it directly to native machine code: standalone, statically linked bare-metal binaries with no .NET runtime, no VM, and no garbage collector.

• Native AOT compilation to Linux x86-64 executables and shared libraries
• JIT execution with rubyc run
• Handwritten frontend, defined IR, pluggable target backends
• Implemented in Rust; hello-world binary of 4,688 bytes

Example: rubyc build hello.rc --target linux_x86_64 -o hello produces a standalone native executable. Explore the source at github.com/rubyc-project.
