Probe::Perl - Information about the currently running perl SYNOPSIS
use Probe::Perl; $p = Probe::Perl->new(); # Version of this perl as a floating point number $ver = $p->perl_version(); $ver = Probe::Perl->perl_version(); # Convert a multi-dotted string to a floating point number $ver = $p->perl_version_to_float($ver); $ver = Probe::Perl->perl_version_to_float($ver); # Check if the given perl is the same as the one currently running $bool = $p->perl_is_same($perl_path); $bool = Probe::Perl->perl_is_same($perl_path); # Find a path to the currently-running perl $path = $p->find_perl_interpreter(); $path = Probe::Perl->find_perl_interpreter(); # Get @INC before run-time additions @paths = $p->perl_inc(); @paths = Probe::Perl->perl_inc(); # Get the general type of operating system $type = $p->os_type(); $type = Probe::Perl->os_type(); # Access values $val = $p->config('foo'); $val = Probe::Perl->config('foo'); $p->config('foo' => 'bar'); # Set locally $p->config_revert('foo'); # Revert DESCRIPTION
This module provides methods for obtaining information about the currently running perl interpreter. It originally began life as code in the "Module::Build" project, but has been externalized here for general use. METHODS
new() Creates a new Probe::Perl object and returns it. Most methods in the Probe::Perl packages are available as class methods, so you don't always need to create a new object. But if you want to create a mutable view of the "" data, it's necessary to create an object to store the values in. config( $key [, $value] ) Returns the "" value associated with $key. If $value is also specified, then the value is set to $value for this view of the data. In this case, "config()" must be called as an object method, not a class method. config_revert( $key ) Removes any user-assigned value in this view of the "" data. find_perl_interpreter( ) Returns the absolute path of this perl interpreter. This is actually sort of a tricky thing to discover sometimes - in these cases we use "perl_is_same()" to verify. perl_version( ) Returns the version of this perl interpreter as a perl-styled version number using "perl_version_to_float()". Uses $^V if your perl is recent enough, otherwise uses $]. perl_version_to_float( $version ) Formats $version as a perl-styled version number like 5.008001. perl_is_same( $perl ) Given the name of a perl interpreter, this method determines if it has the same configuration as the one represented by the current perl instance. Usually this means it's exactly the same perl_inc( ) Returns a list of directories in this perl's @INC path, before any entries from "use lib", $ENV{PERL5LIB}, or "-I" switches are added. os_type( [$osname] ) Returns a generic OS type (e.g. "Unix", "Windows", "MacOS") for the given OS name. If no OS name is given it uses the value in $^O, which is the same as $Config{osname}. AUTHOR
