NAME

       App::perlimports::ExportInspector - Inspect code for exportable symbols

VERSION

       version 0.000045

SYNOPSIS

           use strict;
           use warnings;

           use App::perlimport::ExportInspector ();

           my $ei = App::perlimport::ExportInspector->new(
               module_name => 'Carp',
           );

           my $exports = $ei->explicit_exports;

DESCRIPTION

       Inspect modules to see what they might export.

MOTIVATION

       Since we're (maybe) importing symbols as part of this process, we've sandboxed it a little
       bit by not doing it in App::perlimports directly.

METHODS

       The following methods are available.

   implicit_exports
       A HashRef with keys representing symbols which a module implicitly exports (i.e.  via "use
       Module::Name;". The values represent the import value which you would need in order to
       explicitly import the symbol. Often these will be the same, but there are exceptions. For
       example, a type library may export "is_ArrayRef", but you import it via "use
       My::Type::Library qw( ArrayRef );".

   explicit_exports
       A HashRef with keys representing symbols which a module explicitly exports (i.e.  via "use
       Module::Name qw( foo bar );". The values represent the import value which you would need
       in order to explicitly import the symbol. Often these will be the same, but there are
       exceptions. For example, a type library may export "is_ArrayRef", but you import it via
       "use My::Type::Library qw( ArrayRef );".

       In cases where we cannot be certain about the explicit exports, you can try to fall back
       to the implicit exports to get an idea of what this module can export.

   evals_ok
       Returns true if either implicit or explicit exports can be built without setting $@.

   implicit_export_names_match_values
       Returns true if the keys and values in "implicit_exports" match.

   explicit_export_names_match_values
       Returns true if the keys and values in "explicit_exports" match.

   success_counter
       Returns an integer representing the number of times we were able to execute eval
       statements for this package which did not pollute $@.

CAVEATS

       This may not work with modules using some creative way of managing symbol exports.
