Thought this was going to be an inspiration to me to continue with my pet project of writing my own little programming language. But it starts off on day 8 with him already having written a basic compiler, with no explanation of how he did any of the basics. Still interesting, just not what I thought it was.

Same here. I have been trying the same project as you... and get stuck on the grammar, every.single.time.

Are you done with that part yet?

The C grammar is printed in BNF in the back of K&R and available in machine-readable form in the standards.
