Unusual use of x string repetition operator
Hi, I've played wit x and xx repetition operators and found interesting result using rakudo star: join(|, (1,2) x 10) 1 21 21 21 21 21 21 21 21 21 2 Is this ok? If true please explain this to me :) Because I expected 12121212121212121212 or 12|12|12|12|12|12|12|12|12|12 PS. perl6 --version This is perl6 version 2014.01 built on parrot 5.9.0 revision 0 -- Regards Kamil Kułaga
Re: Unusual use of x string repetition operator
x puts (1,2) array in scalar context, that's why you have 1 2 string repeated 10 times. try xx operator, it works in array context $ perl6 -e 'say join(|, (1,2) xx 10)' 1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2|1|2 bbkr On 10 Feb 2014, at 14:19, Kamil Kułaga teodoz...@gmail.com wrote: Hi, I've played wit x and xx repetition operators and found interesting result using rakudo star: join(|, (1,2) x 10) 1 21 21 21 21 21 21 21 21 21 2 Is this ok?

Hi, Array stringification to 1 2 mislead me that something more complicated comes around.

Re: Unusual use of x string repetition operator
Hi, what about this?
FROGGS r: say ((1,2).join xx 10).join('|')
camelia rakudo-parrot 46234b, rakudo-jvm 46234b, rakudo-moar 46234b:

Re: Unusual use of x string repetition operator
Hi,
The best, because it uses object oriented join. I forgot about it.
