57 |  |  |  |  |
58 |  |  |  |  | Sub::Identify - Retrieve names of code references
59 |  |  |  |  |
60 |  |  |  |  | =head1 SYNOPSIS
61 |  |  |  |  |
62 |  |  |  |  | use Sub::Identify ':all';
63 |  |  |  |  | my $subname = sub_name( $some_coderef );
64 |  |  |  |  | my $p = stash_name( $some_coderef );
65 |  |  |  |  | my $fully_qualified_name = sub_fullname( $some_coderef );
66 |  |  |  |  | defined $subname
67 |  |  |  |  | and print "this coderef points to sub $subname in package $p\n";
68 |  |  |  |  |
69 |  |  |  |  | =head1 DESCRIPTION
70 |  |  |  |  |
71 |  |  |  |  | C<Sub::Identify> allows you to retrieve the real name of code references. For
72 |  |  |  |  | this, it uses perl's introspection mechanism, provided by the C<B> module.
73 |  |  |  |  |
74 |  |  |  |  | It provides four functions : C<sub_name> returns the name of the
75 |  |  |  |  | subroutine (or C<__ANON__> if it's an anonymous code reference),
76 |  |  |  |  | C<stash_name> returns its package, and C<sub_fullname> returns the
77 |  |  |  |  | concatenation of the two.
78 |  |  |  |  |
79 |  |  |  |  | The fourth function, C<get_code_info>, returns a list of two elements,
80 |  |  |  |  | the package and the subroutine name (in case of you want both and are worried
81 |  |  |  |  | by the speed.)
82 |  |  |  |  |
83 |  |  |  |  | In case of subroutine aliasing, those functions always return the
84 |  |  |  |  | original name.
