I'm relatively new to puppet but I used hiera_hash to lookup what I would
consider a "hash" in yaml.
The data I tested with is rather complex in nature but it basically boils
down to a hash of hashes with sub hashes / arrays.
Ex: (my hieradata yaml file, pardon the lack of creativity in the names)
stuff:
FirstNamedStuff:
foo: bar
foo2:
- bara
- barb
foo3:
anotherthing: hi
yetanotherthing: hi2
Puppet (v4.3.2) is returning it as a struct (ex: Struct[{FirstNamedStuff
=> Struct[] }] ) when I was expecting it to be returned as a hash. I'm
using functions written in puppet (not be confused with puppet functions
written in ruby which if you google is what you'll get mostly) with type
information for my parameter. I pass in this value gotten from
hiera_hash("stuff") to my custom function but it fails because it expected
a hash and instead received a struct.
Ex:
function module::get_foo(Hash[String, Struct[{
foo => String,
foo2 => Array[String]
foo3 => Hash[String, String]
}] $myvar)
{
}
I think what's happening is hiera is *always* being treated as a struct for
any hash. I assumed they were interchangeable but it doesn't look like
they are.
There are some cases where I want to enforce a hash, there are other cases
where I want to enforce a struct. Ex:
FirstNameStuff for instance might be user defined, it could be anything.
But foo, foo2, foo3 are all properties that I expect and so a struct makes
sense. foo3's properties might be userdefined so a hash makes sense.
So the question is, can I somehow get this functionality from hieradata and
a custom function? Maybe this is just a bug with 4.3.2? Or is my only
hope to strip off the type information?
