Hello,
I know people hate perl. But it's been around a while and it has the largest
module collection of any language. Check out this page:
http://search.cpan.org/
Click on some of the categories to get a feel for how their modules are named.
Perl searches for modules in the directories listed in the @INC array. This is
basically what the vocabulary-roots variable is. DrScheme uses a collects
variable. Ruby has RUBYLIB.
If Factor can scale up to something the size of CPAN, we'll be doing good. I
think the only way to handle that is with an @INC like mechanism.
When you browse CPAN, note the lack of any hardcoded hierarchy. Authors are
free to name their modules whatever they want. If you have a module named:
Foo::Quark
You can use it with:
use Foo::Quark;
You can get help on it with:
$ perldoc Foo:Quark
It's downloadable as a file named:
Foo-Quark-0.01.tar.gz
Perl modules have to be installed. With a Factor vocabulary, all you have to
do is copy the vocabulary folder to one of the roots.
Here's a nice example of a CPAN module for CAD drawing:
http://search.cpan.org/~ewilhelm/CAD-Drawing-0.26/
Note how it's comprised of various submodules. The vocabs system supports this
sort of organization. See my x and wm vocabs for examples.
