Martin Atkins 096cddb4b7 command/format: Limitation of plans.ResourceInstanceDeleteBecauseNoModule
This is an explicit technical debt note that our plan renderer isn't able
to give a fully-specific hint in this particular case of deletion reason.

This reason code means that at least one of the module instance keys in
the resource's module path doesn't match an instance declared in the
configuration, but the plan data structure doesn't retain enough
information to know which is the first step in the path which refers to
a missing instance, and so we just always return the whole thing.

This would be confusing if we return module.foo[0].module.bar not being
in the configuration as a result of module.foo not using "count"; it would
be better to say "module.foo[0] is not in the configuration" instead.

It would be most ideal to handle all of the different situations that
ResourceInstanceDeleteBecauseWrongRepetition's rendering does, so that we
can go further and explain exactly _why_ that module instance isn't
declared anymore.

We can do neither of those things today because only the Terraform Core
"expander" component knows that information, and we've discarded that
by the time we get to rendering a plan. To fix this one day would require
preserving in the plan information about which module instances are
declared, as a separate sidecar data structure from which resource
instances we're taking actions on, and then using that to identify which
step in addr.Module here first selects an invalid instance.

Alisdair McDiarmid a8b9d086b2 cli: Fix nested single and map diff rendering
Indentation was out by two spaces. This is now consistent with the other
displays of object/map values: four spaces for each nesting level.

Alisdair McDiarmid 2d0349d9a4 cli: Fix diff for nested set unchanged elements
Unchanged elements in nested attributes backed by sets were previously
misrendered as empty objects. This commit removes the additional
brackets and adds a count of unchanged elements.

command/format: improve list nested attribute rendering (#29827)
* command/format: fix list nested attr diff rendering

Previously, diffs only rendered correctly if all changed elements
appeared before all unchanged elements. Once an unchanged element was
found, all remaining elements were skipped. This usually led to the
output being an empty list with a weird amount of space between the
brackets.

* command/format: improve list nested attr rendering

This makes several changes that make diffs for lists clearer and more
consistent:

  * Separate items with brackets instead of only new lines. This better
    matches the input syntax and avoids confusion from the first and
    last brackets implying there is a single item.
  * Render an action symbol for each element of the list
  * Use the correct action symbol for new and deleted items
  * Fix the alignment of opening and closing brackets

I also refactored the structure so it is similar to the set and map
cases to minimize duplication of the new prints.

* Fix re-use of blockBodyDiffResult struct

Martin Atkins 04f9e7148c command/format: Include deletion reasons in plan report
The core runtime is now able to specify a reason for some situations when
Terraform plans to delete a resource instance.

This commit makes that information visible in the human-oriented UI. A
previous commit already made the underlying data informing these new hints
visible as part of the machine-oriented (JSON) plan output.

This also removes the bold formatting from the existing "has moved to"
hints, because subjectively it seemed like the result was emphasizing too
many parts of the output and thus somewhat defeating the benefit of the
emphasis in trying to create additional visual hierarchy for sighted users
running Terraform in a terminal. Now only the first line containing the
main action statement will be in bold, and all of the parenthesized
follow-up notes will be unformatted.

Alisdair McDiarmid d5b5407ccc format: Fix incorrect nesting of Color/Sprintf
Colorizing the result of an interpolated string can result in
incorrect output, if the values used to generate the string happen to
include color codes such as `[red]` or `[bold]`. Instead we should
always colorize the format string before calling functions like
`Sprintf`. This commit fixes all instances in this file.

Alisdair McDiarmid 29999c1d6f command: Render "moved" annotations in plan UI
For resources which are planned to move, render the previous run address
as additional information in the plan UI. For the case of a move-only
resource (which otherwise is unchanged), we also render that as a
planned change, but without any corresponding action symbol.

If all changes in the plan are moves without changes, the plan is no
longer considered "empty". In this case, we skip rendering the action
symbols in the UI.

James Bardin 68ed50616e handle null and unknown values in attr diffs
The code adopted from block diffs was not set to handle null and unknown
values, as those are not allowed for blocks.

We also revert the change to formatting nested object types as single
attributes, because the attribute formatter cannot handle sensitive
values from the schema. This presents some awkward syntax for diffs for
now, but should suffice until the entire formatter can be refactored to
better handle these new nested types.

James Bardin fbfb14142e render empty nested containers as attributes
Don't try to break down containers that are empty to render the diff, so
we can avoid having to check for empty vs null in all cases.

Alisdair McDiarmid ef0181cfbd Add comments explaining how ctySequenceDiff works
The logic behind this code took me a while to understand, so I wrote
down what I understand to be the reasoning behind how it works. The
trickiest part is rendering changing objects as updates. I think the
other pieces are fairly common to LCS sequence diff rendering, so I
didn't explain those in detail.

James Bardin 57aa7c6025 skip drift rendering for deposed resources
Deposed instances have no current state and are only scheduled for
deletion, so there is no reason to try and render drift on these
instances.

Alisdair McDiarmid 5fc3ba37a6 cli: Improve sensitivity change warning output
When an attribute value changes in sensitivity, we previously rendered
this in the diff with a `~` update action and a note about the
consequence of the sensitivity change. Since we also suppress the
attribute value, this made it impossible to know if the underlying value
was changing, too, which has significant consequences on the meaning of
the plan.

This commit adds an equality check of the old/new underlying values. If
these are unchanged, we add a note to the sensitivity warning to clarify
that only sensitivity is changing.

Martin Atkins f40800b3a4 Move states/ to internal/states/
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.
