Can you create a compatible flex .y file?

[tu6ge]

Hi , I am learning flex and bison , and I is learned rust language. and I like rust become it is safte language. I look at src/test/calc.y file many times, it has some rust sentence, so I uncertain it can work with flex. Can you give me some help ?

There's nothing specific to Rust or Yacc/Bison in calc.y, so better read guides/docs about them. I'm not the best candidate to teach you how it works.

I have 0 experience with Flex but from what I know it emits tokens in some predefined format, and so your Parser::yylex method can modify them as needed.
