  • Perl, foreach order

    - by Mike
    Does Perl's foreach loop operator require that the list items be presented in order? For example my @a=(1,2,3); foreach my $item (@a) { print $item; } will always print 1 2 3? I suspect so, but I can't find it documented.

  • Parsing command line options in Perl

    - by Jay Gridley
    Hi guys, I am parsing command line options in Perl using Getopt::Long. I am forced to use prefix - (one dash) for short commands (-s) and -- (double dash) for long commands (ex. --input=file), but problem is, that there is one special option (-r=) so it is long option for its requirement for argument, but it has to have one dash (-) prefix not double dash (--) like other long options. Is possible to setup Getopt::Long to accept these?
