in reply to How to Split on specific occurrence of a comma

Hi

instead of limiting split , I'd rather swallow all splitted cells into a long @array and then loop over that @array with splice to chunk out whatever length you want.

here a little demo in the debugger, looping over the alphabet in chunks of 10

DB<208> @array = a..z DB<209> while ( my @b = splice @array, 0, 10 ) { say "@b" } a b c d e f g h i j k l m n o p q r s t u v w x y z DB<210>

HTH! :)

    I think this approach should work. thanks!

      Your welcome! :)

      on a side note

      This

        $line =~ s/^[^=]*\=//;

      is IMHO better written as

        my ($var,$list) = split /=/, $line, 2; °

      It's not only much easier to read and self-documenting, you'll also have a chance to check if $var eq "Teams"

      And if $var is of no interest you can also write

        my ( undef, $list ) = split /=/, $line;

      debugger demo

      DB<211> $line = "Teams=PATRIOTS,BILLS,DOLPHINS,JETS,COWBOYS,GIANTS,E +AGLES,REDSKINS,BENGALS,OILERS,STEELERS,BROWNS,SEAHAWKS,RAMS,49ERS,RAI +DERS" DB<212> x ($var,$list) = split /=/, $line 0 'Teams' 1 'PATRIOTS,BILLS,DOLPHINS,JETS,COWBOYS,GIANTS,EAGLES,REDSKINS,BENGAL +S,OILERS,STEELERS,BROWNS,SEAHAWKS,RAMS,49ERS,RAIDERS'

      °) the 2 in case you are worried that the character "=" appears in your list elements
