As a hack, I've occasionally done something like:
diff --git a/lib/puppet/application/apply.rb
b/lib/puppet/application/apply.rb
index cc733e1..6ca8f25 100644
--- a/lib/puppet/application/apply.rb
+++ b/lib/puppet/application/apply.rb
@@ -65,7 +65,7 @@ class Puppet::Application::Apply < Puppet::Application
Puppet[:manifest] = command_line.args.shift
end
begin
-
Puppet::Node::Environment.new(Puppet[:environment]).known_resource_types
+ print
ZAML.dump(Puppet::Node::Environment.new(Puppet[:environment]).known_resource_types)
rescue => detail
Puppet.err detail
exit 1
which changes --parseonly to dump the AST forest to stdout instead of just
constructing it and throwing it out. I also typically filter the output
with "grep -v" or some such to skip the stuff I don't care about.
Not sure if that's useful info, but I figured it might be.
