Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.
This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.
For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.
Our main "parse" methods in this package work with hcl.Traversals, but
we're gradually adding helpers to parse these directly froms strings since
the visual noise of doing the traversal parse first is inconvenient in
situations where addresses are coming from non-config locations where
no source information is available anyway.
The zero value of ProviderConfig is not a valid provider config address,
so we'll generate a special string for that in order to make that clear
in case one sneaks in somewhere. This can happen, for example, in the
core flow of resolving provider inheritance during the ProviderTransformer
if a caller attempts to access the resolved provider before that
transformer has run.
These helpers, similar to other such methods on ModuleInstance, are useful
for programmatically constructing provider config addresses, particularly
in tests where this is more straightforward than parsing from strings.
This helper deals with the address wrangling required to find the address
that a provider configuration might inherit from if no explicit
configuration is given and instead configuration is taken from the
parent module.
This method is not generally useful, and is here mainly just to help the
provider-related graph transformations in the main terraform package.
This "kitchen sink" commit is mainly focused on supporting "targets" as
a new sub-category of addresses, for use-case like the -target CLI option,
but also includes some other functionality to get closer to replacing
terraform.ResourceAddress and fill out some missing parts for representing
various other address types that are currently represented as strings
in the "terraform" package.
This is for parsing the type of provider configuration address we write
into state in order to remember which provider configuration is
responsible for each resource.
This package is intended to contain all the functionality for parsing,
representing, and formatting addresses of objects within Terraform.
It will eventually subsume the responsibilities of both the
InterpolatedVariable and ResourceAddress types in the "terraform" package,
but for the moment is just a set of types for representing these things,
lacking any way to parse or format them. The remaining functionality
will follow in subsequent commits.
