Move the information about state from the "caveats" to the main
info section, using similar information to sensitive outputs.
Updates the header of the section from similar inspiration.
We can remove the caveat about changing map elements.
Add a little more text about the intended use case for ignore_changes,
as the common case of fixing erroneous provider behavior should not be
the primary motivation for the maintenance of this feature.
This commit adds an `alltrue` function to Terraform configuration. A
reason we might want this function is because it will enable more
powerful custom variable validations. For example:
```hcl
variable "amis" {
type = list(object({
id = string
}))
validation {
condition = (alltrue([
for a in var.amis : length(a.id) > 4 && substr(a.id, 0, 4) == "ami-"
]))
error_message = "The ID of at least one AMI was invalid."
}
}
```
* Adding not about data-sources and depends-on for 0.12 users
* Bold
* A little more markdown
* A little more markdown for data_sources in 0.12
* Some iteration based on good feedback
The version argument is deprecated in Terraform v0.14 in favor of
required_providers and will be removed in a future version of terraform
(expected to be v0.15). The provider configuration documentation already
discourages use of 'version' inside provider configuration blocks, so it
only needed an extra note that it is actively deprecated.
The subtle difference in keywords when creating vs. accessing locals trips
people up, even more than the "variable" vs. "var" distinction. It deserves its
own subheader on the page, plus a nice noisy callout.
I've just wasted an hour to two hours trying to find the problem to finally realize that although I declare a "locals" block, it's referred to as "local". This is pretty weird! So let's be be clear about this.
* Make sidebar nav in language docs more intuitive
* Minor display fixes for registry docs
* Explain providers in the registry in the providers index
* Revise a bunch of language docs around provider reqs
This is mostly an effort to smooth out some of the explanations, make sure
things are presented in a helpful order, make sure terminology lines up, draw
connections between related concepts, make default behavior more apparent, and
the like. It shouldn't include very much new information, but there might be one
or two things that came out of a conversation somewhere.

As part of documenting the new module for_each capabilities we added a
section noting that shared modules using the legacy pattern of declaring
their own provider configurations would not be compatible with them.
However, that also applies to the new module depends_on and several folks
participating in the beta pointed out that the documentation wasn't
discussing that at all.
In order to generalize the advice, I've moved the old content we had
(since v0.11) recommending against provider configurations in shared
modules out into its own section, now being more explicit that it is
a legacy pattern and not recommended, and then folded the content about
for_each and count, now also including depends_on, into that expanded
section.
As is often the case, that had some knock-on effects on the content on
the rest of this page, so there's some general editing and reorganization
here. In particular, I moved the "Multiple Instances of a Module" section
much further up the page because it's content relevant to users of
shared modules, while the later content on this page is more aimed at
authors of shared modules, including the new section about the legacy
pattern.
We previously covered everything about using providers on a single page,
but that was getting unwieldy already and we now have a lot more to
discuss with v0.13 introducing a new source address syntax and some other
concepts.
Here we split the provider-related content into two parts: "Provider
Requirements" covers how to find and declare dependencies on providers,
and then "Provider Configuration" (formerly just "Providers") then focuses
primarily on how to write zero or more provider configurations for a
particular provider.
Because "Provider Requirements" is now presented before "Provider
Configuration" in the navigation, I've also moved some of the introductory
content about providers in general onto the "Requirements" page. The
first paragraph of that content is duplicated onto the "Configuration"
page for discoverability, but we now link to the requirements page to get
the full story.
