Puppet users - Feb 2013 - Retrieving the name of the module where a define is used

How do I retrieve the name of the module where a define is used ?

Consider the following

file java/manifests/setup.pp

define java::setup (
  $source        = undef,){
    file { $cachedir:
      ensure => ''directory'',
      owner  => ''root'',
      group  => ''root'',
      mode   => ''644''
    }

    file { "${cachedir}/${source}":
      source  => "puppet:///modules/${module_name}/${source}",
      require => File[$cachedir],
    }
# stripped out for readability
}

file mywebapp/manifests/init.pp

# stripped out for readability
  java::setup { ''mywebapp-java'':
    source        => ''jdk-7u7-linux-x64.gz'',
  }
# stripped out for readability

I want the source to be constructed
as  puppet:///modules/mywebapp/jdk-7u7-linux-x64.gz instead of
puppet:///modules/java/jdk-7u7-linux-x64.gz

Try using the variable *caller_module_name* instead

Thanks Nikola. I didn''t know that variable exists. Is there a list of
all available variables somewhere ?

Well you can use calling_module and also all the variables defined in
http://docs.puppetlabs.com/puppet/latest/reference/lang_variables.html#facts-and-built-in-variables

Not sure why calling_module is not there at the moment. There might
be two reasons for this:
* it is more experimental
* it is older and $caller_module_name should be used instead(look at the
link)

Maybe someone can step in and make this more clear to both of us ;)

calling_module isn''t a puppet variable. It''s something special
from the
Puppet backend to Hiera, and I''m not entirely sure how it works or even
whether it currently works. $caller_module_name is a legit puppet variable, 
though.

Hmm I can swear this was discussed here as a recommendation but maybe I
am wrong. Will change my defines to use *caller_module_name*. Thanks for
clarifying this!
