It looks like you want to use the munge hook. Though the docs
<https://docs.puppetlabs.com/guides/custom_types.html> are a bit unclear, I
think it works for property definitions (not just for parameter
definitions). You would put something like this inside your property
definition:
munge do |value|
value.inject({}) do |xlated, kv|
k, v = kv
xlated[k.gsub(/_/, '-')] = v
end
end
Note that that assumes the value is a hash; you may want to use the
validation hook as well to ensure that (or else munge more flexibly).
