| jgaz | Can't seem to match any non-whitespace that recurs twice in a row, as in `/(\S)\1/` in Perl regex. Tried `/ (\S) ** 2 /` and similar; no luck. Any ideas? | 15:06 | |
| lizmat | m: say " a bc def" ~~ / \S ** 2 / | 15:12 | |
| camelia | ｢bc｣ | ||
| jgaz | lizmat, not quite, think Mississippi being matched, because any two identical letters occur twice. | 15:17 | |
| disbot8 | <shimmerfairy> We've got the <same> rule for checking if a character is the same on either side of the current position. | 15:23 | |
| <shimmerfairy> m: say "Mississippi" ~~ m:g/\S <.same> \S/ | |||
| <Raku eval> (｢ss｣ ｢ss｣ ｢pp｣) | |||
| jgaz | Oooh! That's cool. Thanks. | 15:32 | |
| shimmerfairy, confirmed, that works. | 15:34 | ||
| disbot8 | <shimmerfairy> Glad to hear it. Incidentally, if you really need to match a previously-matched substring, there are ways to do it, with a bit of effort. | 15:40 | |

| disbot8 | <antononcube> @jgaz More in the spirit of your Perl code is this: say "Mississippi" ~~ m:g/ ($<c>=\S $<c>+) /; | 17:33 | |
| <antononcube> m: say "Mississippi" ~~ m:g/ ($<c>=\S $<c>+) / | 17:34 | ||
| <Raku eval> (｢ss｣ 0 => ｢ss｣ c => ｢s｣ ｢ss｣ 0 => ｢ss｣ c => ｢s｣ ｢pp｣ 0 => ｢pp｣ c => ｢p｣) | |||
