As of this commit, that layout doesn't exist yet, but I'm isolating the one-line
changes to their own commit to try and keep your eyes from glazing over.
We typically try to avoid making subjective, boasty claims in our
documentation in recent times, but there remained both some older
documentation that we've not recently revised and also some newer examples
that are, in retrospect, also perhaps more "boasty" than they need to be.
We prefer not to use this sort of boasty language because not everyone
using Terraform has the same background and experience, and so what is
"easy" or "intuitive" to one person may not be so to another person, and
that should not suggest that the second person is in any way wrong or
inadequate.
In reviewing some of our use of the word "easy" here I tried as much as
possible to surgically revise the existing content without getting drawn
into a big rewrite, but in some cases the content was either pretty
unsalvageable (due to talking about obsolete features that were removed
long ago) or required some broader changes to make the result hopefully
still get the same facts across. In those cases I've both removed some
content entirely or adjusted larger paragraphs.
This was not an exhaustive review and so I'm sure there's still plenty of
room for similar improvements elsewhere. I also resisted the urge to
update some pages that contain outdated information about currently-active
features.
* website: Update all Learn crosslinks
The URL structure on Learn recently changed, so it's time to update some URLs.

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.
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.
All of the feedback from the experiment described enhancements that can
potentially be added later without breaking changes, so this change simply
removes the experiment gate from the feature as originally implemented
with no changes to its functionality.
Further enhancements may follow in later releases, but the goal of this
change is just to ship the feature exactly as it was under the experiment.
Most of the changes here are cleaning up the experiment opt-ins from our
test cases. The most important parts are in configs/experiments.go and in
experiments/experiment.go .
This guide now lives at:
- https://learn.hashicorp.com/terraform#getting-started
...and terraform.io has been redirecting to there for quite a while. This commit
removes the extra copy so that the text of the two versions doesn't drift, and
updates existing links to point to the new location.
The existing "type" argument allows specifying a type constraint that
allows for some basic validation, but often there are more constraints on
a variable value than just its type.
This new feature (requiring an experiment opt-in for now, while we refine
it) allows specifying arbitrary validation rules for any variable which
can then cause custom error messages to be returned when a caller provides
an inappropriate value.
variable "example" {
validation {
condition = var.example != "nope"
error_message = "Example value must not be \"nope\"."
}
}
The core parts of this are designed to do as little new work as possible
when no validations are specified, and thus the main new checking codepath
here can therefore only run when the experiment is enabled in order to
permit having validations.
* website/formatdate: update example
The given example was showing HOUR:MONTH instead of HOUR:MINUTE
Fixes#22598
* website/import: remove reference to no-longer-working option
Users can no longer supply `-config=""` to tell Terraform not to load
configuration for import.
Fixes#22294
* website/provisioners: `host` is required in connection blocks
Fixes#21877
* website/variables: clarify variable definition precedence
It was not entirely obvious that a variable could not be assigned
multiples times in a single source.
Fixes#21682
* website/backend/local: add `workspace_dir` attribute
Fixes#21391
* website/output: `sensitive` outputs are redacted in output
Fixes#21502
* website/backends: sidebar order tweak
It makes sense for backend 'configuration' to appear before 'init'.
Fixes#13796
* Revert "website/formatdate: update example"
This reverts commit ccd93c86ddd15a21625c0767702ee1cc62e77254.
The Terraform Enterprise brand has now been split into two parts:
- Terraform Cloud is the application that helps teams use Terraform together,
with remote state storage, a shared run environment, etc.
- Terraform Enterprise is the on-premise distribution that lets enterprises run
a private instance of the Terraform Cloud application.
The former TFE docs have been split accordingly.
* docs: update plan command documentation. Fixes#19235
* docs: added a missing reserved variable name. Fixes#19159.
* website: add note that resource names cannot start with a number
* website: add some notes to the 0.12 upgrade guide
This commit is a wide-ranging set of edits to the pages under
/docs/configuration. Among other things, it
- Separates style conventions out into their own page.
- Separates type constraints and conversion info into their own page.
- Conflates similar complex types a little more freely, since the distinction is
only relevant when restricting inputs for a reusable module or resource.
- Clarifies several concepts that confused me during edits.
This adopts a more guide-like writing style, similar to what prior commits
have done to some other subsections of this section.
Since we already have a whole top-level section devoted to modules, there
is no need for full coverage of all of their features here. Instead, this
section focuses on an an initial introduction to what modules are and
the basics of their usage within the Terraform language. We then link
to the main modules section for the full details.
We've historically been somewhat inconsistent in how we refer to the
type of object defined by "variable" blocks in configuration. Parts of
our documentation refer to them as "input variables" or just "variables",
while our implementation refers to them as "user variables".
Since Terraform Registry is now also referring to these as "Inputs", here
we standardize on "Input Variable" as the fully-qualified name for this
concept, with "variable" being a shorthand for this where context is
obvious. Outside of this context, anything that can be referred to in
an interpolation expression is generically known as a "variable", with
Input Variables being just one kind, specified by the "var." prefix.
While this terminology shift is not critical yet, it will become more
important as we start to document the new version of the configuration
language so we can use the generic meaning of "variable" there.
The modules mechanism has changed quite a bit for version 0.11 and so
although simple usage remains broadly compatible there are some
significant changes in the behavior of more complex modules.
Since large parts of this were rewritten anyway, I also took the
opportunity to do some copy-editing to make the prose on this page more
consistent with our usual editorial voice and to wrap the long
lines.
