drew (Oct 19 2024 at 17:37):i also don't see a way to find the size of a string
drew (Oct 19 2024 at 17:39):looks like countUtf8Bytes
Dan G Knutson (Oct 19 2024 at 20:07):You probably want this:
https://github.com/roc-lang/unicode
https://roc-lang.github.io/unicode/CodePoint/#utf8Len
String length is weirder than it looks, and the byte count will be different than the character count for non-english languages. If you're only working with ascii then you get to mostly not think about it.
Edit: I just saw your other thread; for AOC byte length is probably fine (and maybe I'm telling you things you know :sweat_smile:)
Brendan Hansknecht (Oct 19 2024 at 21:32):For advent of code, I advice not using strings as the input
Brendan Hansknecht (Oct 19 2024 at 21:32):Just commit to List U8. It is the most correct and what Roc really pushes you to work with
Luke Boswell (Oct 19 2024 at 21:33):For Advent Of Code, you can checkout Hannes' ASCII package https://github.com/Hasnep/roc-ascii
Luke Boswell (Oct 19 2024 at 21:34):Lot's of nice helpers there :heart:
