Starting a series on lexing and LALR-1 parser generators using leex and yecc. The series is really focused on the “by example” part since it took me a long time to get started with these tools.
The first example is lexing and parsing advent of code 2024 day 3. Hope you enjoy!
Sounds amazing! 
Focusing on “by example” is a fantastic way to make lexing and LALR-1 parsing approachable. Using Advent of Code Day 3 as a practical case is a brilliant idea - looking forward to learning from your insights! 
Part 2 is now available Leex and yecc by example: part 2 | Chiroptical’s Blog
I discuss the lexer and parser for advent of code day 4 and a simplification I was able to do to day 3.
