Follow up on an idea in #31: use the Racket lexer to lex double-quoted strings in a grammar, thereby giving them all the semantics of Racket strings, and preventing any corner cases. This solution can’t be extended to single-quoted strings, however, because even with readtable tomfoolery to recognize a single quote as an opening delimiter for a string, the string still needs to be closed with a double quote. (I don’t know why this should be so, but it is the documented behavior.) Therefore single-quoted strings still are subject to the homegrown lexing solution and the flaws therein. Still, I don’t see that single-quoted strings have ever been a documented feature of brag (or its predecessor ragg). Perhaps they could be dropped altogether. For now, this solution is satisfying, because double-quoted strings are the dominant notation, and this PR will make them as good as they can be. |
