Re^4: "use"ing from dynamic namespace

I suspected something like that.

I guess my next try would be:

sub config_module {
   $self = shift;
   return ref($self) . '/Config.pm';
}

And just always calling it as a method?

for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";

...almost there :) but you'd still have to get rid of the `"::"` in case of a package name like `"Foo::Module"`. Also, you could write `ref($self) \|\| $self`, in which case you could call `load_config` on both the class or an object instance. #!/usr/bin/perl package Base::Module; sub load_config { my $class = shift; my $module = $class->config_module; print "about to require $module\n"; #require $module; } sub config_module { $self = shift; my $pkg = ref($self) \|\| $self; $pkg =~ s#::#/#g; # optionally remove "/Module" # $pkg =~ s#/[^/]+\z##; return "$pkg/Config.pm"; } package Foo::Module; use base qw(Base::Module); sub new { return bless {}, shift; } package main; Foo::Module->load_config(); Foo::Module->new()->load_config(); __END__ $ ./727519.pl about to require Foo/Module/Config.pm about to require Foo/Module/Config.pm [download] BTW, the sub `config_module` would work the same way when declared in Foo::Module, though - if I'm understanding you correctly - your idea was to put it in the base class...

...almost there :) but you'd still have to get rid of the "::" in case of a package name like "Foo::Module". Also, you could write ref($self) || $self, in which case you could call load_config on both the class or an object instance.

#!/usr/bin/perl

package Base::Module;

sub load_config {
    my $class   = shift;
    my $module  = $class->config_module;
    print "about to require $module\n";
    #require $module;
}

sub config_module {
    $self = shift;
    my $pkg = ref($self) || $self;

    $pkg =~ s#::#/#g;
    # optionally remove "/Module"
    # $pkg =~ s#/[^/]+\z##;

    return "$pkg/Config.pm";
}


package Foo::Module;
use base qw(Base::Module);

sub new {
    return bless {}, shift;
}


package main;

Foo::Module->load_config();
Foo::Module->new()->load_config();

__END__
