finally after months and months of just planning and doing boring stuff a piece of code that was really just fun to code and plan for some days:
i just wrote my first "real" parser for a simple DSL. so much fun! i just really can recommend that to everybody.
i've use a parser combinator. the concept of this parser combinator ist to combine simple parsers (like when it starts with a number or a "-" and continues with numbers then its an integer etc) into a big one. i've written it in c# and used "Sprache" first and after some time i switch to "Superpower". a really great lib, but lacks a bit of documentation. anyway, i've your're interested in these things and want learn how your "daily code" gets parsed i would recommend that to you! :)
greetings to all fellow devRanters and happy coding / parsing! :)1 -
I swear to god, getting Chumsky to do my bidding has almost taken longer than writing a parser by hand. I'm not looking for operator precedence, I'm not looking for complicated rules or anything, the main part of my language is literally just S-expressions, with some top level bells and whistles.
I don't even have a working lexer yet because I wanted to use this piece of shit library which usually matches the fewest possible characters to parse significant newlines but the Padded combinator takes as much whitespace at the end as it can find, and a host of other atomics don't actually adhere to the library's lazy principle in their procedural implementation. I've had enough. I'm going to bed, and tomorrow I'm writing tickets.
Actually, I'll probably also write PRs because I actually want the fixes to exist and not just complain about the problems, but I also really want to complain before I get started on that because I spent about two weeks just on this bullshit.3
