Is there a way to see find out if a module is installed for use?

[Peter Foley]

Hi List,

Is there a puppet command to find out what modules are available for use or at least a module to return a boolean value if you pass it a module name you wish to use?

I am looking to do something like:

if is_module_available(stdlib) {

  # Use stdlib capability

}

else {

  # Use my own version

}

Thanks,

Peter

I've used something like this:

Facter.add(:zabbix_version) do

  setcode do

    output = %x{/bin/rpm -qa --queryformat "%{VERSION}" zabbix-agent}

  end

end

But rpm queries can be expensive.

Hi Len,

Thanks for the reply, sorry I should have been a bit clearer I
actually meant puppet modules.

Ie I want to be able to establish if a puppet module is installed in
the one of the modulepath locations

root@core modules/puppet# puppet config print modulepath
/etc/puppet/modules:/usr/share/puppet/modules

I guess I could go down a similar path and write a fact to query the
module directories and then query against this. Any other
suggestions?

Thanks,

Peter
