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.
