Alisdair McDiarmid	843c50e8ce	lang: Further limit the console-only type function ... This commit introduces a capsule type, `TypeType`, which is used to extricate type information from the console-only `type` function. In combination with the `TypeType` mark, this allows us to restrict the use of this function to top-level display of a value's type. Any other use of `type()` will result in an error diagnostic.	4 years ago
Alisdair McDiarmid	691b98b612	cli: Prevent overuse of console-only type function ... The console-only `type` function allows interrogation of any value's type. An implementation quirk is that we use a cty.Mark to allow the console to display this type information without the usual HCL quoting. For example: > type("boop") string instead of: > type("boop") "string" Because these marks can propagate when used in complex expressions, using the type function as part of a complex expression could result in this "print as raw" mark being attached to a collection. When this happened, it would result in a crash when we tried to iterate over a marked value. The `type` function was never intended to be used in this way, which is why its use is limited to the console command. Its purpose was as a pseudo-builtin, used only at the top level to display the type of a given value. This commit goes some way to preventing the use of the `type` function in complex expressions, by refusing to display any non-string value which was marked by `type`, or contains a sub-value which was so marked.	4 years ago
Martin Atkins	cdd9464f9a	Move lang/ to internal/lang/ ... This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.	5 years ago
