Re: Question on s///eg

Here's some not so thouroughly tested code:

my @channels = (1, 1, 0, 1, 1, 1, 0);
my $str = join "", @channels;
my @range;
push @range, join "-", ($-[0], $+[0]-1) while $str =~ m/(1+)/g;
print join ",", @range;
[download]

prints 0-1,3-5

Update: I must add that this may not work for perl versions older than 5.6.0.
