  • How are macros dealt with for incremental compilation?

    Indeed this is the problem I'm having with my proc macro crates lexgen and parsegen. In the case of lexgen, the proc macro is actually quite fast for realistic inputs, but the compiler spends a lot of time checking and generated code with cargo check (which I suspect rust-analyzer also uses). In the case of parsegen the proc macro does some analyses and takes some time. In both cases I have to split my proc macro code (not the proc macros, the code that uses the proc macros) to separate crates so that they won't be recompiler/re-analyzed as I work on the code.
  • If you're not using a lexer generator for your compiler, why?

    I'm working on my own lexer and parser generators, and I'm trying to understand why some projects don't use lexer and parser generators and use hand-written lexers and parsers.
