If those aren't super helpful we'd love to make them better.
Hmm, I've read:
http://docs.puppetlabs.com/guides/custom_types.html
2 or 3 times when I started, but somehow I missed the links to:
http://docs.puppetlabs.com/guides/complete_resource_example.html
and
http://docs.puppetlabs.com/guides/provider_development.html
Maybe you could add a link to next article at the end of the current one?
Now that I've gone through the second one, I finally get the idea of
param vs property.
Also, I think you should add puppet code snippet in "Complete resource
example", so that the reader can get an idea about how the puppet code
will look like and how the "engine" (type/provider) behind it works and
should be implemented. For someone who starts from scratch it's hard to
understand why all that code if you didn't provide resource example for
the code you want to write.
So, IMHO, that article should look something like this:
"if you want to write a custom type for foo, which has param bar and
property boo, like this:
foo {"myfoo":
ensure => present,
bar => 'something',
boo => 'something_else',
}
you should start by coding type...."
Or at lease, this kind of snippet should be present at the bottom of the
article so people can connect those two things.
Next thing I didn't see is - when to use param and when to use property?
What is current best practice and what do puppet-guys suggest...
And finally - hashes... Maybe another (advanced) article describing
hashes and how to generate hash from current system state, and how to
apply settings from hash to the system (in property methods). I could
help about this one because I've really pushed to get it done with just
reading f5_pool and f5_message providers, and trying/failing
consistently until I figured it out...
