Ok – so it seems the the underlying base classes of my provider are expecting
the parameters and their validations from the exec type instead of my new type
– makes sense. I was able to test that theory out by adding the parameters
(and in many cases copying the parameters from the exec type) being validated
to my new type, but that’s not exactly what I was hoping for. I did get to the
point where it’s writing out the temp ps1 file and executing, but now I have
some challenges on the return output.
I was trying to avoid direct execution of calling cmd.exe with powershell and
re-inventing the wheel because it’s been done so well with the powershell
provider, and it avoids some of the escape hell with double quotes if trying to
pass them on the command line.
I’m likely going about this the wrong way (e.g. going overboard) but if anyone
wants to provide guidance from the realm of sanity, please feel free.

Subject: [Puppet Users] Help with provider inheritance of Josh Cooper's Exec
PowerShell Provider
I'm as newbie as they come to both Ruby and custom provider development, so
apologies if I'm missing the obvious up front. :)
I want to write a custom type/provider to manage IIS Settings. I realize that
there are at least 3 IIS modules in the forge already (and we are using one of
them) but I am attempting to write my own because 1) I want to learn how to
write custom providers and not just defined types in Puppet DSL and 2) The
existing IIS modules don't hit all the granular configurations I need to manage
so I have a bunch of execs I need to reign in.
That said, the first type/provider I'm playing with is to simply enable and
disable Logging in IIS at the server and site level. I am trying to inherit
from Josh Cooper's Powershell provider because it executes PowerShell, does it
well:)
I sometimes see the temp powershell file being written to temp then disappear,
but it seems I've hit a wall on the exists? method right out of the gate. When
I do a puppet run, I get the error:
Error: /Stage[main]/Test_tools/Iis_logging[TestLogging]: Could not evaluate:
Invalid parameter cwd(:cwd)
Any insight would be appreciated. Relevant code below.
Running with --trace shows (partial stack trace):

Provider I've Defined (just showing the exists? method - that's the first
hurdle)
(I've defined (copied) command(:powershell) in this provider because of the
lack of inheritance of the commands method, but I get the same error with or
w/out it)
(run method is already redefined in Josh's provider, which is inherited from
the exec provider - didn't think I need to do antying else)
