[Puppet Users] facter to return version of an installed package

[Helmut Schneider]

Hi,

before I reinvent the wheel:

Does anyone know a custom fact that returns the version of an installed
package (if it is installed)?

I assume it would be something like

Facter.add(:package_version) do
  setcode do
    osfamily = Facter.value(:osfamily)
    case osfamily
    when /ubuntu|debian/
      Facter::Util::Resolution.exec("dpkg -l '*$my_package*' | grep
^ii")
    when 'freebsd'
      Facter::Util::Resolution.exec("pkg info -ix $my_package*")
    end
  end
end

but I have not found out yet how to pass a variable to facter.

helmut@ubuntu:~$ puppet -V
6.4.2
helmut@ubuntu:~$ facter -v
3.13.2
helmut@ubuntu:~$

Thank you!
