File::Spec::Native(3pm) User Contributed Perl Documentation File::Spec::Native(3pm)
NAME
File::Spec::Native - Use native OS implementation of File::Spec from a subclass
VERSION
version 1.003
SYNOPSIS
# This serves little purpose on its own but can be useful in some situations
# For example:
use Path::Class 0.24;
# convert foreign file type into native type
# without having to know what the current OS is
foreign_file(Win32 => $win32_path)->as_foreign("Native");
# or to build a file-spec dynamically (possibly taking the type from input):
my $type = get_requested_file_spec(); # can return "Native"
foreign_file($type => $file_path);
# having $type be "Native" is an alternative to having to do:
my $file = $type ? foreign_file($type, $file_path) : file($file_path);
DESCRIPTION
This module is a stupid hack to make the default File::Spec behavior available from a subclass. This can be useful when using another
module that expects a subclass of File::Spec but you want to use the current, native OS format (automatically detected by File::Spec).
For example: "as_foreign" in Path::Class (as of version 0.24) allows you to translate a Path::Class object from one OS format to another.
However, there is no way to specify that you want to translate the path into the current, native OS format without guessing at what that
format is (which may include peeking into @File::Spec::ISA).
This module @ISA File::Spec.
