This is another part of the existing ephemeral_values experiment, taking
a value of any type that might have ephemeral values in it and returning
a value of the same type which has any ephemeral value replaced with a
null value.
The primary purpose of this is to allow a module to conveniently return an
object that would normally contain nested ephemeral values -- such as an
instance of a managed resource type that has a write-only attribute --
through an output value that isn't declared as ephemeral. This would then
expose all of the non-ephemeral parts of the object but withhold the
ephemeral parts. In the case of write-only attributes, it exposes the
normal attributes while withholding the write-only ones.
The name of this function could potentially change before stabilization,
because it's quite long and clunky. I did originally consider
"nonephemeral" to match with the existing "nonsensitive", but that didn't
feel right because "nonsensitive" removes the sensitive mark while
preserving the underlying value while this function removes the mark and
the real value at the same time. (It would not be appropriate to have a
function that just removes the ephemeral mark while preserving the value,
because correct handling of ephemerality is important for correctness
while sensitivity is primarily a UI concern so we don't need to be quite
so picky about it.)
* Add metadata functions command skeleton
* Export functions as JSON via cli command
* Add metadata command
* Add tests to jsonfunction package
* WIP: Add metadata functions test
* Change return_type & type in JSON to json.RawMessage
This enables easier deserialisation of types when parsing the JSON.
* Skip is_nullable when false
* Update cli docs with metadata command
* Use tfdiags to report function marshal errors
* Ignore map, list and type functions
* Test Marshal function with diags
* Test metadata functions command output
* Simplify type marshaling by using cty.Type
* Add static function signatures for can and try
* Update internal/command/jsonfunction/function_test.go
