| msiism | Is there a shorter way to get the index number of the last character in a string than `chars($word) - 1`? | 13:49 | |
| disbot3 | <nahita3882> if strings were iterable, .end would be it but it gives the wrong answer | 14:14 | |
| <nahita3882> so, no most probably | |||
| <nahita3882> method form with .chars saves 1 character :y | |||
| <nahita3882> a longer, bad way is $word.match(/$/).pos.pred | 14:16 | ||
| <nahita3882> lastly, one might need to be careful for empty strings | |||
| msiism | Looking at it again, the `chars($word) - 1` is actually pretty concise. | 14:30 | |
| What I would really like to have is a way to obtain a letter from a certain index, without having to use substr. | 14:31 | ||
| Something like `getchar($string, $index)`. | 14:32 | ||
| I mean character, of course, not letter. Just currently woking only with letters here… | 14:59 | ||
| disbot3 | <librasteve> msiiam: once you embrace unicode as graphemes, then the idea of a character independent of the bytes before and after it no longer holds | 15:01 | |
| <librasteve> dev.to/bbkr/unicode-vs-utf-4g8c <=== this set of posts is a bit of an eye opener | 15:03 | ||

| msiism | To break an unconditional loop, do I simply use return? | 21:37 | |
| Uhh… no, I don't, because return is for returning from routines. | 21:39 | ||
| Seem like there's no break statement in Raku. | |||
| disbot3 | <antononcube> See last; | 21:40 | |
| <antononcube> docs.raku.org/syntax/last | 21:41 | ||
| msiism | Okay, thanks. | 21:43 | |
