ToddAndMargo Is there a way to ask .contains if there is any instance of swept letters.  I am wanting to know if ANY of the following are found "a..z".  So if "c" is in the string, .contains says true 02:30
Dr.Doom {.sort,{sort .[0],[R-] $_ } ... *.cache.grep({[eq] $_})} 03:08
i want to genrate this sequence untill the elements as all the same same elements 03:09

ToddAndMargo Is there a way to do it with .contains? 03:32
03:36 camelia joined
Dr.Doom don't no just picked up the language few days ago 03:40
(3 7) (3 4) (1 3) (1 2) (1 1) (0 1) 03:41
for example it must stop at (1,1)
ToddAndMargo I think the best way is going to be with regex.  I copied my exampled to vpaste:    vpaste.net/ebRuT 03:43
Dr Doom, you a human or a robot responder? 03:53
Dr.Doom sub f($a,$b){ gather{ unless $a eq $b{ take ($a,$b); ($a,$b) = ($b,$a - $b); } } } 03:55
this is what I want to achive
human, what kind of question was that?
ToddAndMargo I have had to suffer with so many (annoying) AI robot responder today, that I really really curious (discord bot shounds like an AI) 03:57

Dr.Doom (39 => True 38 => True 6 => True 26 => True 10 => True 33 => True 21 => True 46 => True 4 => True 49 => True 25 => True 9 => True 14 => True 15 => True 35 => True 22 => True 34 => True) why does converting a set to list results in this 08:57
say ((1..100).grep(*.is-prime) ==> {$_.grep(* + 2 ⊆ $_)}()) 09:45
how to get this to work
m: ((1..100).grep(.is-prime) ==> {$_.grep( + 2 ⊆ $_)}()).say
Raku eval Exit code: 1 The iterator of this Seq is already in use/consumed by another Seq (you might solve this by adding .cache on usages of the Seq, or by assigning the Seq into an array) in block <unit> at main.raku line 1
nemokosch What will it do when "working"? Just to be on the same page 09:46
Dr.Doom need to get all the twin primes between 1..100
nemokosch Something with twin primes
Okay
Dr.Doom m: my @a = Array(1..100); say (@a.grep(.is-prime) ==> {$_.grep( + 2 ⊆ $_)}()).say 09:49
Raku eval Exit code: 1 The iterator of this Seq is already in use/consumed by another Seq (you might solve this by adding .cache on usages of the Seq, or by assigning the Seq into an array) in block <unit> at main.raku line 1
nemokosch The Seq comes from grep 09:50
So the immediate fix would be to chain .cache on the prime sequence 09:51
Dr.Doom thanks 09:52
nemokosch Do you know rotor, by the way?
m: (1..100).grep(*.is-prime).rotor(2 => -1).say 09:53
Raku eval ((2 3) (3 5) (5 7) (7 11) (11 13) (13 17) (17 19) (19 23) (23 29) (29 31) (31 37) (37 41) (41 43) (43 47) (47 53) (53 59) (59 61) (61 67) (67 71) (71 73) (73 79) (79 83) (83 89) (89 97))
nemokosch Take two values, then skip over -1 ie roll back 1 09:54

Dr.Doom wow 11:22
that's awesome 11:23
nemokosch and then you could do stuff lik 11:32

casually leaving it open for an hour 12:17
concentration issues be like... anyway
m: (1..100).grep(*.is-prime).rotor(2 => -1).grep({ [-] $_ == 2}).say
Raku eval ((2 3) (3 5) (5 7) (7 11) (11 13) (13 17) (17 19) (19 23) (23 29) (29 31) (31 37) (37 41) (41 43) (43 47) (47 53) (53 59) (59 61) (61 67) (67 71) (71 73) (73 79) (79 83) (83 89) (89 97))
nemokosch not quite
the betrayal 12:18
I will probably type it out, the precedence is funny 12:19
m: (1..100).grep(*.is-prime).rotor(2 => -1).grep({ .[1] - .[0] == 2 }).say
Raku eval ((3 5) (5 7) (11 13) (17 19) (29 31) (41 43) (59 61) (71 73))
nemokosch dang
