I need to be able to include a line in a template, based on presence and value of a variable, something like this: # file.erb blah blah blah <% if role == "fast" -%> this line is here now <% end -%> I only want the line to be included if $role exists and is equal to fast. If $role doesn''t exist, or doesn''t equal "fast", it shouldn''t include the line: Jul 24 19:59:40 lonengbld01 puppetmasterd[3095]: Failed to parse template repo/R edHat-4/extras.repo: Could not find value for ''role'' at /etc/puppet/modules/repo /manifests/init.pp:121 on node blah What would be the correct syntax?

I don''t want to have to edit every node definition in order to get that line in just a couple of nodes. Maybe change the class so it concats another template/file onto the end of it if $role is set, although I''m not quite sure how to do that yet without experimentation. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Thats what a default value is for. Take this as an example: define your_definition($role=default) { file { "/path/to/your/file": ensure => present, content => template("your_template") } } Now, if you call it with your_definition { "resource_name": } $role will have the value "default" in your template if you call it with your_definition { "resource_name": role => "fast", } your $role will have the value fast Not what you want, since you would have to flick a switch on your node definition, but I tend to deal these issues like this: class yourmodulename { $role = "default" your_definition { "resource_name": role => "$role", } } define yourmodulename::your_definition($role=default) { file { "/path/to/file/to/controll": ensure => present, content => template("yourmodulename/templatename") } } Then you can subclass this and override the $role=default So the subclass in the module would look like: class yourmodulename::yoursubclass inherits yourmodulename { $role = "fast" Your_definition[''resource_name''] { role => "$role" } } In that case every place you include the subclass the template is fed with "fast" as the value for $role. Im sure you can find other ways to deal with it all well.

Just a note...
defined?(foo) doesn''t work.
You have to use:
has_variable?("foo")
Found that out the hard way :-/.
