nighthawk

smol compiler, using Python, QBE (compiler backend), and Lark (parser generator)

why

idk, i was bored and then i made this...

but how do i run it??

nix-shell # use nix like a chad

python src/main.py < tests/expressions.lark > out.ssa # Outputs QBE IR
qbe out.ssa > out.s # Turn QBE IR into assembly
gcc out.s -o out # Turn assembly into binary

./out # woah magic

but what if i don't want to use nix?

install nix and refer to but how do i run it??.

but seriously, how do i do run it without nix???

don't.

okay but actually...

• Install Python 3.10 (or later)
• Install QBE (or compile from scratch)

pip install lark

# Run the commands from the other thing, minus the `nix-shell`
