Puppet users - Sep 2010 - Can I access data structure internal to providers

Hi

I would like to be able to access the hash "info2hash" in
lib/puppet/provider/package/sun.rb which is a list of all Solaris packages
on a Sun server

Is it possible to query this so that I don''t have to run "pkginfo
-l"
myself, and probably create a fact for each package with its version number?
My Ruby is basic, so I''m not quite sure how to read providers.

What I am trying to do is have my own Solaris package provider that is
versionable without having to resort to supporting Blastwave/Sunfreeware
like external scripts. The last comment for the "update" definition
doesn''t
make me comfortable "This will probably often fail"

Thanks

John

It sounds like you want to subclass the provider yourself so you get
that hash/method for free.

Does this mean editing/changing sun.rb or creating my own mysun.rb and
somehow inherit sun.rb and all its goodies?

Do you have any pointers where I can up to speed with this sort of thing?

Thanks

I mean the latter, inheritance.

I would probably have a look at the apt* providers and how they
inherit from the dpkg provider?
