Config::Extensions(3perl) Perl Programmers Reference Guide Config::Extensions(3perl)NAME
Config::Extensions - hash lookup of which core extensions were built.
SYNOPSIS
use Config::Extensions '%Extensions';
if ($Extensions{PerlIO::via}) {
# This perl has PerlIO::via built
}
DESCRIPTION
The Config::Extensions module provides a hash %Extensions containing all the core extensions that were enabled for this perl. The hash is
keyed by extension name, with each entry having one of 3 possible values:
dynamic
The extension is dynamically linked
nonxs
The extension is pure perl, so doesn't need linking to the perl executable
static
The extension is statically linked to the perl binary
As all values evaluate to true, a simple "if" test is good enough to determine whether an extension is present.
All the data uses to generate the %Extensions hash is already present in the "Config" module, but not in such a convenient format to
quickly reference.

Class::Trait::Config - Trait configuration information storage package.
SYNOPSIS
This package is used internally by Class::Trait to store Trait configuration information. It is also used by Class::Trait::Reflection to
gather information about a Trait.
DESCRIPTION
This class is a intentionally very C-struct-like. It is meant to help encapsulate the Trait configuration information in a clean easy to
access way.
This class is effectively sealed. It is not meant to be extended, only to be used.
METHODS
new Creates a new empty Class::Trait::Config object, with fields initialized to empty containers.
name
An accessor to the "name" string field of the Class::Trait::Config object.
sub_traits
An accessor to the "sub_traits" array reference field of the Class::Trait::Config object.
requirements
An accessor to the "requirements" hash reference field of the Class::Trait::Config object. Note, the requirements field is a hash
reference to speed requirement lookup, the values of the hash are simply booleans.
methods
An accessor to the "methods" hash reference field of the Class::Trait::Config object.
overloads
An accessor to the "overloads" hash reference field of the Class::Trait::Config object.
conflicts
An accessor to the "conflicts" hash reference field of the Class::Trait::Config object. Note, the conflicts field is a hash reference
to speed conflict lookup, the values of the hash are simply booleans.
clone
Provides deep copy functionality for the Class::Trait::Config object. This will be sure to copy all sub-elements of the object, but not
to attempt to copy and subroutine references found.
