Oh, it looks like my X86-16 boot sector C compiler that I made recently [1]. Writing boot sector games has a nostalgic magic to it, when programming was actually fun and showed off your skills. It's a shame that the AI era has terribly devalued these projects.

I may be the author.. enjoy! It was an absolute blast making this!

Compare that to the C compiler in 100,000 lines written by Claude in two weeks for $20,000 (I think was posted on HN just yesterday)

The way hashing is used for tokens and for making a pseudo symbol table is such an elegant idea.

Beautiful, but make sure to quickly add 2023 to the title.

Lacking support for structs, I think this is too minimalistic to be called "a C compiler".

> I wrote a fairly straight-forward and minimalist lexer and it took >150 lines of C code
was it supposed to be "<150"?

Why is it called a C Compiler if it's a subset of C?

Nice. Very K&R-ish. Not a bad thing.
