How to split a string based on comma, but not based on comma in double quote

fast solution with comb, take anything but not " nor , or take quoted string

my $str = '1,2,3,"4,5,6",7,8';
.say for $str.comb: / <-[",]>+ | <["]> ~ <["]>  <-["]>+ / ;

as @melpomene suggested, use the Text::CSV module works too.

use Text::CSV;

my $str = '123,456,"78,91",abc,"de,f","ikm"';
for csv(in => csv(in => [$str], sep_char => ",")) -> $arr {
   .say for @$arr;
}

which output:

123
456
78,91
abc
de,f
ikm
