Config::Extensions - hash lookup of which core extensions were built.
use Config::Extensions '%Extensions'; if ($Extensions{PerlIO::via}) { # This perl has PerlIO::via built }
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:
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.
