LL(*), with IDE tooling and visual debugger for all parsing phases.
ANTLR combines lexical analysis and parsing, flex+bison, into a single tool. To me, ANTLR4 sets the bar pretty high. I'm not opposed to learning a new tool like parser combinators but I'd need an article that showed the differences between ANTLR4 and PCs, showing how it was much easier in PCs rather than it was just 2017.
I'd add that ANTLR has really good documentation.
ANTLR is a parser generator, isn't it? Do you mean parser combinators where you write generators?
Ugh. Fixed. Thanks.
But I really would want to read the ANTLR4 vs PCs article. I'm very happy with ANTLR4. But tools is tools.
