Custom Lexer #15

Closed maxsnew closed 1 year ago

maxsnew commented 1 year ago

From trying out the current parser, I think some of the error messages would be seriously improved by a better lexer. This would also allow us to integrate (line) comment syntax (#14) easily.

As for how to do it, https://lib.rs/crates/logos looks like a fairly straightforward library, and http://lalrpop.github.io/lalrpop/lexer_tutorial/002_writing_custom_lexer.html is a tutorial on how to integrate the lexer with LALRPOP
