Fateful is a CLI tool foring with my custom CPU, F8ful.
It contains an emulator and an assembler.
Fateful can be installed through cargo via cargo install --git https://github.com/commonkestrel/fateful.
The assembler can be used with the fateful asm or fateful assemble command to assembler f8ful assembly into f8ful machine code.
The input and output are both optional, and default to stdin and stdout respectively.
There are sixteen instructions in f8ful assembly.
Peripherals are a way to extend the emulator, simulating a memory-mapped peripheral. This is through the use of dynamic library loading, so you can create a peripheral in any language that supports the C ABI.
There is a Rust crate (fateful_peripheral)
to make creating peripherals easy.
