what would you use to write a parser in 2021?

• grammars-v4

  29 9,816 9.6 ANTLR

  Grammars written for ANTLR v4; expectation that the grammars are free of actions.

  

Oh come on. Just on github alone, there's over 200 ANTLR4 grammars available many for well known languages created before ANTLR was even invented --- how exactly are those languages constrained?

• parser-demo

  13 18 0.0 Lex

  Good source layout with Flex and Bison

Bison can be configured to avoid every single one of those problems. I use reentrant versions (both with and without push parsing) in my demo project. I admit I didn't bother with named references or cleaning up after errors.
