NAME¶

Sub::Identify - Retrieve names of code references

SYNOPSIS¶

    use Sub::Identify ':all';
    my $subname = sub_name( $some_coderef );
    my $p = stash_name( $some_coderef );
    my $fully_qualified_name = sub_fullname( $some_coderef );
    defined $subname
        and print "this coderef points to sub $subname in package $p\n";

DESCRIPTION¶

"Sub::Identify" allows you to retrieve the real name of code references. For this, it uses perl's introspection mechanism, provided by the "B" module. It provides four functions : "sub_name" returns the name of the subroutine (or "__ANON__" if it's an anonymous code reference), "stash_name" returns its package, and "sub_fullname" returns the concatenation of the two. The fourth function, "get_code_info", returns a list of two elements, the package and the subroutine name (in case of you want both and are worried by the speed.) In case of subroutine aliasing, those functions always return the original name.
