NAMEConfig::Extensions - hash lookup of which core extensions were built. SYNOPSISuse Config::Extensions '%Extensions'; if ($Extensions{PerlIO::via}) { # This perl has PerlIO::via built } DESCRIPTIONThe 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. AUTHORNicholas Clark <nick@ccl4.org>
