Martin Atkins	479c6b2466	move "configschema" from "config" to "configs" ... The "config" package is no longer used and will be removed as part of the 0.12 release cleanup. Since configschema is part of the "new world" of configuration modelling, it makes more sense for it to live as a subdirectory of the newer "configs" package.	8 years ago
Martin Atkins	c937c06a03	terraform: ugly huge change to weave in new HCL2-oriented types ... Due to how deeply the configuration types go into Terraform Core, there isn't a great way to switch out to HCL2 gradually. As a consequence, this huge commit gets us from the old state to a _compilable_ new state, but does not yet attempt to fix any tests and has a number of known missing parts and bugs. We will continue to iterate on this in forthcoming commits, heading back towards passing tests and making Terraform fully-functional again. The three main goals here are: - Use the configuration models from the "configs" package instead of the older models in the "config" package, which is now deprecated and preserved only to help us write our migration tool. - Do expression inspection and evaluation using the functionality of the new "lang" package, instead of the Interpolator type and related functionality in the main "terraform" package. - Represent addresses of various objects using types in the addrs package, rather than hand-constructed strings. This is not critical to support the above, but was a big help during the implementation of these other points since it made it much more explicit what kind of address is expected in each context. Since our new packages are built to accommodate some future planned features that are not yet implemented (e.g. the "for_each" argument on resources, "count"/"for_each" on modules), and since there's still a fair amount of functionality still using old-style APIs, there is a moderate amount of shimming here to connect new assumptions with old, hopefully in a way that makes it easier to find and eliminate these shims later. I apologize in advance to the person who inevitably just found this huge commit while spelunking through the commit history.	8 years ago
Martin Atkins	a16ca2ec53	lang: new package for the runtime parts of the config language ... Whereas package "configs" deals with the static structure of the configuration language, this new package "lang" deals with the dynamic aspects such as expression evaluation. So far this mainly consists of populating a hcl.EvalContext that contains the values necessary to evaluate a block or an expression. There is also special handling here for dynamic block generation using the HCL "dynblock" extension, which is exposed in the public interface (rather than hiding it as an implementation detail of EvalBlock) so that the caller can then extract proper source locations for any result values using the expanded body. This also includes the beginnings of a replacement for the function table handling that currently lives in the old "config" package, but most of the functions are not yet ported and so this will expand in subsequent commits.	8 years ago
