It seems to me LL and LR parser generators are overrated, and hand-written recursive descent is best in practice. I understand why academics teach them, but not why some spend so long on different parsing techniques, nor why hobbyists who just want to compile their toy language are directed to them.
I work in PL, and from my first compiler to today, have always found recursive descent easiest, most effective (less bugs, better error diagnostics, fast enough), and intuitive. Many popular language compilers use recursive descent: I know at least C# (Roslyn) and Rust, but I believe most except Haskell (GHC) and ocaml.
The LR algorithm was simple once I
learned it, and yacc-like LR (and antlr-like LL) parser generators were straightforward once I learned how to resolve conflicts. But recursive descent (at least to me) is simpler and more straightforward.
LR being more expressive than LL has never mattered. A hand-written recursive descent parser is most expressive: it has unlimited lookahead, and can modify
parsed AST nodes (e.g. reordering for precedence, converting if into if-else).
The only solution that comes close is tree-sitter, because it implements GLR, provides helpful conflict messages, and provides basic IDE support (e.g. syntax highlighting) almost for free. But it’s a build dependency, while recursive descent parsers can be written in most languages with zero dependencies and minimal boilerplate.
