Martin Atkins	67d8a5137b	rpcapi+stacks: Stacks runtime can see whether experiments are allowed ... We allow experiments only in alpha builds, and so we propagate the flag for whether that's allowed in from "package main". We previously had that plumbed in only as far as the rpcapi startup. This plumbs the flag all the way into package stackeval so that we can in turn propagate it to Terraform's module config loader, which is ultimately the one responsible for ensuring that language experiments can be enabled only when the flag is set. Therefore it will now be possible to opt in to language experiments in modules that are used in stack components.	2 years ago

Martin Atkins	9a943af56d	stackruntime: Arbitrary expression evaluation ... Here we introduce a new evaluation phase for the stacks runtime called "inspect", which aims to provide a read-only view of a configuration and an associated state snapshot. The main idea of this is to use it as a more convenient vehicle for unit testing despite it not really being viable to decompose the main evaluation logic into smaller parts: the language features are all directly interdependent on one another, but we can at least minimize our interactions with the Terraform modules runtime when we're testing anything other than actually planning and applying components. However, this also gives an opportunity to expose evaluation of arbitrary expressions in a similar manner as "terraform console", which is for now just another debugging aid but will probably someday appear as a Stacks-flavored version of the "terraform console" command.	2 years ago
