tbrowder hi, i'm using $string.split(/some regex/, :k) on a long string. that works. 13:34
m: my @s = "1abc2abc3abc".split(/\d/, :k); say $_.Str for @s; 13:36
camelia
0
abc
0
abc
0
abc
13:39 jpn joined
tbrowder hm, i meant to use :v but i see @s puts out two strings for each match. docs don't really explain that, nor does it have a good example of such. 13:39
my use case is extracting text from pdfs. 13:40
and the best way to iterate over the "pairs" is? 13:41
Voldenet iirc .split(//, :v) returns Seq 13:44
and it looks iterable 13:45
13:45 jpn left 13:48 Manifest is now known as Manifest0 13:50 haxxelotto left, haxxelotto joined 13:51 jpn joined 13:57 jpn left
Voldenet m: for "1abc2def3ghi".split(/\d/, :v).batch(2) -> $pair { $pair.say }; 14:04
camelia ( ï½¢1ï½£)
(abc ï½¢2ï½£)
(def ï½¢3ï½£)
(ghi)
Voldenet consider this
or
14:04 haxxelotto left
Voldenet m: for "1abc2def3ghi".split(/\d/, :v :skip-empty).batch(2) -> $pair { $pair.say }; 14:04
camelia (ï½¢1ï½£ abc)
(ï½¢2ï½£ def)
(ï½¢3ï½£ ghi)
14:05 haxxelotto joined
Voldenet nevermind, that :skip-empty is a bad idea because it makes iterations unpredictable 14:10
14:15 jpn joined 14:41 xinming left 14:42 Sgeo joined 14:43 xinming joined 14:45 haxxelotto left 15:07 haxxelotto joined, tadzik left, tadzik joined
tbrowder you need to add .Str to the match to get a usable string 15:08
and i want to join the match.Str and its result into a new string 15:11
a space-separated string
lizmat m: say "1abc2def3ghi".split(/\d/, :v).join(" ") 15:12
camelia 1 abc 2 def 3 ghi
tbrowder $pair.Str.say maybe
lizmat: i need "1 abc", "2 abc", ... a list 15:13
lizmat and what if the string begins with "foo", like "foo1abc2def" ? 15:14
Voldenet I'm starting to believe that using grammars is a better solution 15:15
antononcube @Voldenet Better than using LLMs? 15:19
lizmat m: .say for "1abc2def3ghi".split(/\d/, :v).skip.map(-> $a, $b { "$a $b" }) 15:20
camelia 1 abc
2 def
3 ghi
Voldenet m: for "1abc2def3ghi".match(/$<k>=(\d)$<v>=(<-:N>+)/, :g) -> $pair { $pair.say };
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
lizmat tbrowder: ^^ in case there's no string before the first numeric
Voldenet uh oh 15:21
m: for "1abc2def3ghi".match(/$<k>=(\d)$<v>=(<-:N>+)/, :g) { .say }; 15:22
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
Voldenet odd, it works for me
m: for "1abc2def3ghi".match(:g, /$<k>=(\d)$<v>=(<-:N>+)/) { .say };
camelia Too many positionals passed; expected 1 argument but got 2
in block <unit> at <tmp> line 1
Voldenet either way, the above should work, contrary to what bot says 15:24
lizmat doesn't work for me eitherv :-(
Voldenet m: for "1abc2def3ghi" ~~ m:g/$<k>=(\d)$<v>=(<-:N>+)/ { .say }; 15:25
camelia Too many positionals passed; expected 1 argument but got 2

lizmat Voldenet: which version of Rakudo are you using ?
Voldenet not a specific version, maybe that's my problem 15:27
lizmat if it's pre 2023.12, then that could be the reason
Voldenet 6.0d, seems ancient
lizmat 5606fb657c
linkable6 (2023-12-15) github.com/rakudo/rakudo/commit/5606fb657c Make Match.print more aware of its surroundings
lizmat afk&
Voldenet m: for "1abc2def3ghi" ~~ m:g/$<k>=(<:Nd>+)$<v>=(<-:Nd>+)/ { say .<k>, .<v> }; 15:28
camelia ｢1｣｢abc｣
｢2｣｢def｣
｢3｣｢ghi｣
Voldenet yeah, that was it
