  • 77db95791a cl-frontend: Improve the line-editing capabilities in REPL mode. - Note: This adds a dependency on Crossterm, to set the terminal into raw mode. This could be eliminated by linking the libraries Crossterm uses directly...

  • f25685560a conlang: Tokenize punctuation (resolves #9) Things left to consider: - token::Type enum is getting fairly large. breaking it up could invoke substantial code bloat - Compound operators might make more sense at the parser level - Compound-assign operators are ripe for syntactic desugaring, but there must be some reason it's done separately in other languages. - Operators like FatArrow may still make sense at the tokenizer level, regardless. - What is a lexer? A miserable pile of parsers! - Operator overloading, or user-defined operators? Hmm... John 2023-09-28 00:11:31 -05:00
