Try "\n" instead.


Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.

    '\n' will also work:
    #!/usr/bin/perl my $string = "Bla\nBlo\nBloe"; print join("|", split('\n', $string));
    This works, and the reason becomes clear when you run it through B::Deparse:
    $ perl -MO=Deparse split.pl my $string = "Bla\nBlo\nBloe"; print join('|', split(/\n/, $string, 0)); split.pl syntax OK

      You live and learn :) What a stupid special exception!

        It's not really a special exception, the first argument to split() is a regular expression, irrespective of what the delimiters are, the only special case there being the difference between / / and ' '.

        /J\

        Some playing around shows it's not an exception:
        #!/usr/bin/perl my $string = "Bla\nBlo\nBloe"; print join("|", split('something', $string));
        This code is parsed as
        ~$ perl -MO=Deparse split.pl my $string = "Bla\nBlo\nBloe"; print join('|', split(/something/, $string, 0)); split.pl syntax OK
        The same goes for double quotes. split() expects a regex, but apparently will settle for things in quotes and interpret the string as a regex. Indeed, you live and learn :-)
