| drudgesentinel | I was trying to split a raku regex up earlier- is this a sane approach? my $date-regex = rx/ $<year> = /d ** 4 '-' $<month> = /d ** 2 '-' $<day> = /d ** 2 / | 23:37 | |
| I gave up on using this approach, but was hoping to use named captures to print lines in more readable format | 23:38 | ||
| an example string: 2023-06-22T19:12:16+00:00 | |||
| so if i wanted to grab the year, month, day out of this via a regex capture (and in my particular case this date format can be assumed) | 23:39 | ||
| the thing would compile, but I couldn't figure out how to pull out the individual matches from a .match | |||
| roguerakudev | Shouldn't those /d's be \d's? | 23:41 | |
| nemokosch | Do you have a JS background? In JS, you can indeed look up keys of a hash as if it was an attribute of an object but you cannot do that in most languages | 23:46 | |
| drudgesentinel | Yes, sorry. Was hastily typing pseudocode | ||
| Yes also, though I'm not a 'real' programmer most of my experience is in node | 23:47 | ||
| roguerakudev | Oh, I see what you mean now | ||
| nemokosch | For the better or worse, I think this really sticks from JS, this mentality that hashes and records/objects are the same thing from different angles | 23:48 | |
| In Raku, you can do a hash lookup using {} or <> so quite nicely <year> called on the match object would work presumably | 23:49 | ||
| roguerakudev | Yes, that's what I was trying to find | 23:50 | |
| nemokosch | I'd double check the syntax and precedence of named captures just to be sure | ||
| roguerakudev | you can treat the resulting match like a hash | ||
| so $<submatch> is going to default to looking at $/ (most recent match), but if you didn't match in a way that sets $/, you need to look up on whatever you assigned into with something like $match-obj<submatch> | 23:51 | ||
