(if your modules are written well, all that should be necessary is ... <snip>)

That'll work if the current Ivy interface is via class/object methods. However, if the current interface is via exported functions/symbols, then the above won't automatically be enough: the functions from Xxx::Ivy will likely only be exported up to Ivy, when really it's Ivy's caller who wants those functions.

dominus's ModuleBundle can shine light here, as can Exporter's export_to_level method.

blyman
setenv EXINIT 'set noai ts=2'

Another option is namespace munging:

  package Ivy; # in Ivy.pm
  
  { 
    no strict 'refs';
    *{"Xxx::Ivy::"} = *{"Ivy::"};
  }

That should handle most exporting and inheritance issues by making the two packages equivalent...

thanks for your enlightment

Originaly Ivy.pm was only function based and it was only possible to use one Ivy bus. It has been extended so that this functionnal interface still works, but usually we are now using a class/instance interface style. Usually there is only one instance of Ivy bus. I think the main exception is when we developped some GUI applications plug-in's. In those plug-ins' a new part of the GUI is added as an external module, and this GUI part is communicating through new instances of Ivy.

In my current knowledge of perl and according many responses to my quest, I am sure building a full wrapper is possible. The real point now is whether it is worth such complexity as currently this module is quiet simple to understand. My feelings are it does not deserve such complexity if the Ivy name could become a new root name in the CPAN.

Any way, I will ask the question on the appropriate mailing list on the CPAN.

Then there is always goto ;)
