perldoc perlvar
namely the $^O variable that holds your OS name e.g:
C:\>perl -e "print $^O"
MSWin32
also while use statements do happen at compile time, meaning you cannot
conditionally include stuff, you can always use require instead.
perldoc -f use
Quote:
It is exactly equivalent to
BEGIN { require Module; import Module LIST; }
End quote.
You can also check out do and import in perlfunc.
Another tip, see how it is done in modules, e.g. from:
C:\Perl\lib\File\Spec.pm
my %module = (MacOS => 'Mac',
MSWin32 => 'Win32',
os2 => 'OS2',
VMS => 'VMS',
epoc => 'Epoc',
NetWare => 'Win32', # Yes, File::Spec::Win32 works on NetWare.
symbian => 'Win32', # Yes, File::Spec::Win32 works on symbian.
dos => 'OS2', # Yes, File::Spec::OS2 works on DJGPP.
cygwin => 'Cygwin');
my $module = $module{$^O} || 'Unix';
require "File/Spec/$module.pm";
@ISA = ("File::Spec::$module");
etc...
Hope this helps.
BTW: this is the first time I'm viewing the File::Spec source. reading
bits of interesting code is a great way to learn.
