Re: Re: Traversing variables in a namespace

Using eval is overkill in this case. It is more efficient and probably more straightforward to disable strict 'refs' and use symbolic reference to extract a variable's value from the symbol table:

for $name (keys %::) 
{ 
  no strict 'refs';
  $val = $$name;
}

If you remember that %main:: is a hash of globs, then a simple derefence works, doesn't worry strict and allows you to get all types of vars. But you may only want scalars, and not a scalar version of almost everything. `for (keys %main::) { $val = ${ *{ $main::{$_} }{SCALAR} }; }` [download]	[reply] [d/l]

Sure, but take care when you have constants declared. You can't extract them using dereferecing. See Re: Get your system configuration from a man page.. Jeroen "We are not alone"(FZ)	[reply]
