Re: Platform independant directory separator

Use the canonpath function in the File::Spec::Functions module. It's part of the Perl's core distribution.

use File::Spec::Functions qw/ canonpath /;

# it's a good idea to use relative path for portability

my $platform_independent_path =
       canonpath "../data/somepath/somedata.txt";

my $directory_separator =
       canonpath "/";

`my $platform_independent_path = canonpath "../data/somepath/somedata.txt"; my $directory_separator = canonpath "/";` [download] Erm. No. All canonpath does is clear up a directory in to a canonical for for a specific platform - it's not platform independent in any way. For example running your code on a Mac OS 9 box would set `$directory_separator` to "/" when it would more accurately be ":".
