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:
- 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.
