The Logos programming language is a hobby language intended for extreme simplicity and ease of interoperation with the OS. Currently it supports only the ARM64 architecture, but it is designed to be easily extensible to other architectures.

Everything is 64 bits.

Preprocess (m4, cpp, etc), assemble and link any way you like.

You can link it with any library of your chosing. I usually use the Linux C standard library. For MacOS, a template libc.a is provided in the libc/ directory.

pip install build
python -m build

pip install dist/logos-0.0.1-py3-none-any.whl

python -m logos examples/fib.l -o fib.s
as -o fib.o fib.s
ld -o fib fib.o -lc  # -L libc/macos/arm64 (for MacOS)
./fib

• Implement optimization step
• Testing for generated assembly
• Implement easier way to initialize large arrays with values
• RISC-V backend
• x86_64 backend

Thanks André Bittencourt and Lucie Meznikova for your support and motivation throughout the development of this project. I would never have gotten this far without encouragement :)
