Alisdair McDiarmid	356cee7b89	typeexpr: Add test coverage for optional modifier	4 years ago
Alisdair McDiarmid	bf9f733ca2	typeexpr: Import tests from hashicorp/hcl ... This package is a fork of the HCL ext/typeexpr package, but we dropped the tests when bringing it across. This commit imports those tests verbatim.	4 years ago
James Bardin	1f359bab03	internal/typeexpr: staticcheck ... diagnostics were appended to diags shadowing the intended value.	5 years ago
Martin Atkins	0bbbb9c64b	configs: Experimental support for optional object type attributes ... This builds on an experimental feature in the underlying cty library which allows marking specific attribtues of an object type constraint as optional, which in turn modifies how the cty conversion package handles missing attributes in a source value: it will silently substitute a null value of the appropriate type rather than returning an error. In order to implement the experiment this commit temporarily forks the HCL typeexpr extension package into a local internal/typeexpr package, where I've extended the type constraint syntax to allow annotating object type attributes as being optional using the HCL function call syntax. If the experiment is successful -- both at the Terraform layer and in the underlying cty library -- we'll likely send these modifications to upstream HCL so that other HCL-based languages can potentially benefit from this new capability. Because it's experimental, the optional attribute modifier is allowed only with an explicit opt-in to the module_variable_optional_attrs experiment.	6 years ago
