ExtUtils::InferConfig(User Contributed Perl DocumentatExtUtils::InferConfig(3)NAMEExtUtils::InferConfig - Infer Perl Configuration for non-running
interpreters
SYNOPSIS
use ExtUtils::InferConfig;
my $eic = ExtUtils::InferConfig->new(
perl => '/path/to/a/perl'
);
# Get that interpreters %Config as hash ref
my $Config = $eic->get_config;
# Get that interpreters @INC as array ref
my $INC = $eic->get_inc;
DESCRIPTION
This module can determine the configuration and @INC of a perl
interpreter given its path and that it is runnable by the current user.
It runs the interpreter with a one-liner and grabs the %Config hash via
STDOUT capturing. Getting the module load paths, @INC, works the same
way for @INC entries that are plain paths.
METHODS
new
Requires one named parameter: "perl", the path to the perl interpreter
to query for information.
Optional parameter: "debug => 1" enables the debugging mode.
get_config
Returns a copy of the %Config::Config hash of the intepreter which was
specified as a parameter to the constructor.
The first time this method (or the get_inc method below) is called, the
perl binary is run. For subsequent calls of this method, the
information is cached.
get_inc
Returns a copy of the @INC array of the intepreter which was specified
as a parameter to the constructor. Caveat: This skips any references
(subroutines, "ARRAY" refs, objects) in the @INC array because they
cannot be reliably stringified!
The first time this method (or the get_config method avove) is called,
the perl binary is run. For subsequent calls of this method, the
information is cached.
CAVEATS
This module cannot get the non-plain (i.e. non-string) entries of the
@INC array!
SEE ALSO
You can use this module with ExtUtils::Installed to get information
about perl installations that aren't currently running.
