RE: PerlModule options?
Hi again Stas Perrin, So, its a no-can-do then. I'll keep putting the use in every module to import the symbols in the proper namespace. Alternatively I guess I could probably use the functions with fully qualfied name Apache::ReadConfig::myFunction(), however this would add extra typing and this is exactly what I was trying to escape from. Thanks everyone for your time and kind answers. Cheers, Lian Sebe, M.Sc.

You can preload registry scripts using Apache::RegistryLoader, but this doesn't remove the need for an explicit import. __ Stas BekmanJAm_pH -- Just Another mod_perl Hacker http://stason.org/ mod_perl Guide --- http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com

If you do it there, the symbols you want will only get imported into the Apache::ReadConfig namespace. You will not be able to call them in other scripts without importing them there too. - Perrin

RE: PerlModule options?
Hi Perrin, I see your point. However I'm speaking about one simple templating module exporting 2 functions that are used to generate HTML in every other module on the server. So it'll be pollution but bearable ;-) Thank you, Lian Sebe, M.Sc.
