As you could've guessed, considering the language is not even named yet, it's still WIP. You can see examples in examples/ directory, though at the current moment they are closer to just tests, the only "real" example being recursive fibonacci program in examples/recursive_fib.fsh. The language goal is to provide playground in compiler development to me.

• Tests
• Enough features to write complex programs
• More optimizations
• Standard library to not dependent on libc
• FP features
• Replace GAS with my own assembler
• Make my own linker

• PowerPC
• MIPS
• x86_32
• PDP-8 (currently broken)
• ARM
• RISC-V
• ..?

$ cc build.c -o build && ./build run

You'll get the examples built in .build/examples/. It will try to build and test them for all platforms. You'll need compilers and VMs for that.

It was quite hard, you can even see gap on my github activity when I was doing it (August of 2025, not to say it was the only reason why I didn't made any commits, but definetly one of). It took me about 3 attemts to get it to point I'm happy with.
