Calling a global from a global???

Hi there

I have searched on google and through the forums for this one.
Is it possible to call one global from another eg.

Code:

global1 sub { return "hehe"; } 

global2 sub {return global1;}

When I try this, the template I use <%global2%> in, complains that global1 doesn't exist... Frown

Thanks.

Hi,

Only way I know of how to do it (appart from putting into the Custom.pm file and calling with Custom::func_name()), is to do like so:

Code:
sub { 

  my $val = other_sub_inside();  

   sub other_sub_inside { 
      # do something here 
   } 

}

Hope that helps.

Cheers

You can load the globals file, ie:

Code:
sub { 
    local $@; 
    my $globals = do "/path/to/globals.txt" or return "Unable to load globals: $!"; 
    my $out = eval "$globals->{your_other_global}"; 
    return $out->() if (! $@ && ref($out) eq 'CODE') ; 
    return "Compilation of global failed: $@"; 
}

The globals file may already be stored in memory so you may not need to load it - there might be a global variable holding it somewhere. I've not checked.
