Martin Atkins	58b48f4bab	provider/terraform: Use new convention for function names ... When we added these functions we hadn't yet settled on a single convention for how provider-contributed functions ought to be named, and so these followed the convention previously used for Terraform's own built-in functions. We've now decided to use the new provider namespace as an opportunity to partially fix the historical design error of naming functions as all lowercase without any separation between words. This makes the provider functions inconsistent with the built-in functions, but should at least hopefully encourage the provider functions to be consistent with one another, so that the rule for which to use is relatively easy to remember. This also switches the word order because the provider functions convention prefers the verb to come first: encode_tfvars instead of tfvarsencode.	2 years ago
Martin Atkins	573c2db658	provider/terraform: Terraform-specific encoding functions ... Using the new possibility of provider-contributed functions, this introduces three new functions which live in the terraform.io/builtin/terraform provider, rather than being language builtins, due to their Terraform-domain-specific nature. The three new functions are: - tfvarsencode: takes a mapping value and tries to transform it into Terraform CLI's "tfvars" syntax, which is a small subset of HCL that only supports key/value pairs with constant values. - tfvarsdecode: takes a string containing content that could potentially appear in a "tfvars" file and returns an object representing the raw variable values defined inside. - exprencode: takes an arbitrary Terraform value and produces a string that would yield a similar value if parsed as a Terraform expression. All three of these are very specialized, of use only in unusual situations where someone is "gluing together" different Terraform configurations etc when the usual strategies such as data sources are not suitable. There's more information on the motivations for (and limitations of) each function in the included documentation.	2 years ago
