Perl::OSType

NAME

Perl::OSType - Map Perl operating system names to generic types

VERSION

version 1.002

SYNOPSIS

  1.   use Perl::OSType ':all';
  3.   $current_type = os_type();
  4.   $other_type = os_type('dragonfly'); # gives 'Unix'

DESCRIPTION

Modules that provide OS-specific behaviors often need to know if the current operating system matches a more generic type of operating systems. For example, 'linux' is a type of 'Unix' operating system and so is 'freebsd'.

This module provides a mapping between an operating system name as given by $^O and a more generic type. The initial version is based on the OS type mappings provided in Module::Build and ExtUtils::CBuilder. (Thus, Microsoft operating systems are given the type 'Windows' rather than 'Win32'.)

USAGE

No functions are exported by default. The export tag ":all" will export all functions listed below.

os_type()

  1.   $os_type = os_type();
  2.   $os_type = os_type('MSWin32');

Returns a single, generic OS type for a given operating system name. With no arguments, returns the OS type for the current value of $^O . If the operating system is not recognized, the function will return the empty string.

is_os_type()

  1.   $is_windows = is_os_type('Windows');
  2.   $is_unix    = is_os_type('Unix', 'dragonfly');

Given an OS type and OS name, returns true or false if the OS name is of the given type. As with os_type , it will use the current operating system as a default if no OS name is provided.
