| Tirifto | I wonder: is there some way I can match several strings/elements at most once in whatever order in a regular expression? | 00:45 | |
| Basically something like this: /«[ a || ab || ac || abc || acb || b || ba || bc || bac || bca || c || ca || cb || cab || cba ]»/, but written more like this: /«[ a || b || c ]¤»/, where ¤ means ‘match this once or more, but without any of the alterations repeating’. | 00:51 | ||
| alternations* I guess I could insert pieces of code to keep track of this, but this feels like something a more elegant solution might exist for. `o` | 00:52 | ||
| (I also suppose I could just generate combinations for <a b c> in this example, but I’m more generally curious if regexes have any combination-like manipulations or the like.) | 01:02 | ||

| deoac | How would I create a regex which is an alteration of the elements of a list? E.g. create `/'foo'|'bar'|'baz'/` from `<foo bar baz>` | 21:23 | |
| librasteve | m: my @l = <foo bar baz>; my $r = /<@l>/; say 'foo' ~~ $r; | 22:11 | |
| Raku eval | ｢foo｣ | ||
| deoac | Thanks, I clearly was overthinking it. | 23:06 | |
