I wrote https://codewords.recurse.com/issues/seven/dragon-taming-with-tailbiter-a-bytecode-compiler https://codewords.recurse.com/issues/seven/dragon-taming-wit... about a tutorial-level compiler written in itself. Of course, a recommendation from someone who's learned from it instead of from the author would give a better signal. I also recommended the same Wirth book as lboasso, and a couple other books, down at the bottom of the page.
