I use URI:
#!/usr/bin/perl
use strict;
use warnings;
use URI;
my $base_uri = URI->new( '/home/httpd/project/' );
while (my $path = <DATA>) {
chomp($path);
my $absolute = URI->new_abs( $path, $base_uri );
printf "%s + %s: %s\n", $base_uri->canonical, $path, $absolute->cano
+nical;
}
__DATA__
../another/
subdir/
../../../etc/very/dangerous
../project/
update: it seems that I didn't understand the question, sorry.
update2: However, it seems that
URI::file does understand OS differences and does what you want:
use URI::file;
my $base_uri = URI::file->new( URI::file->cwd );
while (my $path = <DATA>) {
chomp($path);
my $absolute = URI::file->new_abs( $path, $base_uri );
printf "%s + %s: %s\n", $base_uri->canonical, $path, $absolute->file
+;
}
