declare package from variable

Is it possible to declare a package name in a ".pm" file from a variable?

Ex. - file Jon.pm

Code:
 my $p = "buddy::Jon"; 
package $p; 
... rest of module...

Thanks,

- Jonathan

Hi,

Can't say I've ever tried it, but I would imagine you could. Have you tried it? =)

Andy,

I'm experiementing with the notion of installing a plugin that can work on GForum, GLinks, and GCommunity...

Example, the Tables plugin.

All the includes I can just use an if statement, but it seems difficult to declare the package name...

So I would need something along the following:

Code:
 if ($ENV{SCRIPT_FILENAME} ~= m/community.cgi/) { 
package Plugins::Community::Jon; 
} 
else { 
package Plugins::Jon; 
}

Obviously that won't work, but I'm stipulating that it is possible somehow.

Any ideas?

Thanks,

- Jonathan

Hi,

Mmm - in that case, not sure it would work (cos I believe packages need to be declared prior). However, it can't hurt to try Smile
