Puppet users - Dec 2010 - puppetmasterd --compile: repeatable YAML output?

Hi all,

I''ve recently started using "puppetmasterd --compile" to
validate changes to
my manifests before I push them out onto the puppetmaster, which is a great 
help in spotting syntax errors, missing resources and the like.

However, something I''d really like to be able to do, is to make a
change
which _should_ have no effect on the manifest for a particular node, and 
verify that it _does_ have no effect. This is hard to do at present, because 
the ordering of elements inside the generated YAML is unpredictable - it 
appears to change even between subsequent runs of an identical manifest, and 
certainly between runs where the manifest has changed due to a 
side-effect-free refactoring. This means that text-based diffing of the 
generated YAML doesn''t work.

Is there a way to force a consistent order on the generated YAML? Failing 
that, does anyone have a recommendation for a "YAML diff" tool that
can show
substantive differences between the compiled manifests ?

Cheers,

Chris

  Chris.
  We are doing a big refactor and migration from .25 to 2.6.  I just
started looking into using https://github.com/ripienaar/puppet-catalog-diff
to do some catalog comparisons before I roll out the upgraded puppet/
manifests.
  This sounds pretty close to what your looking for.
  HTH.  Derek.

Perfect - that''s exactly what I needed.  Thanks!
