I would write that as
my @images = ( [], [] );
{
my( @imgstr ) = split /\|/, $str, 2;
@{ $images[0] } = $imgstr[0] =~ m/(\w+\.jpg)/gi;
@{ $images[1] } = $imgstr[1] =~ m/(\w+\.jpg)/gi;
}
because
- using parens with built-in functions is ugly , extra typing
-
split takes regex as 1st argument, and you're only expecting it to return 2 parts at most
- avoid slice syntax when you're not taking a slice ($images[0])
- avoid pretend arrays, use real arrays (@imgstr)
- limit scope of temporary variables
Actually I would write
my @images;
{
my @imgstr = split /\|/, $str, 2;
push @images, [ $_ =~ m/(\w+\.jpg)/gi ] for @imgstr;
}
or actually
my @images = map { [ $_ =~ m/(\w+\.jpg)/gi ] } split /\|/, $str;
Yes, the last one is how I would normally write something like that, its funny how digesting someone else s code plays tricks on you :)
