Martin Atkins	ea81e75a4e	command: utility for rendering tfdiag diagnostics ... This new method showDiagnostics takes any value that would be accepted by tfdiags.Append and renders it to the UI. This is intended to encourage consistent handling of the different kinds of errors and diagnostics that can be produced, and allow richer error objects like the HCL2 diagnostics to be easily unwrapped and shown in their full-fidelity.	9 years ago
Martin Atkins	fe4cfd03b5	command/format: restore "(forces new resource)" caption ... In 3ea1592 the plan rendering was refactored to add an extra indirection of producing a display-oriented plan object first and then rendering from that object. There was a logic error while adapting the existing plan rendering code to use the new display-oriented object: the core InstanceDiff object sets the "Destroy" flag (a boolean) for both DiffDestroy and DiffDestroyCreate, and so this code previously checked r.Destroy to recognize the "destroy-create" case. This was incorrectly adapted to a check for the display action being DiffDestroy, when it should actually have been DiffDestroyCreate. The effect of this bug was to cause the "(forces new resource)" annotations to not be displayed on attributes, though the resource-level information still correctly reflected that a new resource was required. This fix restores the attribute-level annotations.	9 years ago
Martin Atkins	83414beb8f	command: various adjustments to the diff presentation ... The previous diff presentation was rather "wordy", and not very friendly to those who can't see color either because they have color-blindness or because they don't have a color-supporting terminal. This new presentation uses the actual symbols used in the plan output and tries to be more concise. It also uses some framing characters to try to separate the different stages of "terraform plan" to make it easier to visually navigate. The apply command also adopts this new plan presentation, in preparation for "terraform apply" (with interactive plan confirmation) becoming the primary, safe workflow in the next major release. Finally, we standardize on the terminology "perform" and "actions" rather than "execute" and "changes" to reflect the fact that reading is now an action and that isn't actually a _change_.	9 years ago
Martin Atkins	3ea159297c	command/format: improve consistency of plan results ... Previously the rendered plan output was constructed directly from the core plan and then annotated with counts derived from the count hook. At various places we applied little adjustments to deal with the fact that the user-facing diff model is not identical to the internal diff model, including the special handling of data source reads and destroys. Since this logic was just muddled into the rendering code, it behaved inconsistently with the tally of adds, updates and deletes. This change reworks the plan formatter so that it happens in two stages: - First, we produce a specialized Plan object that is tailored for use in the UI. This applies all the relevant logic to transform the physical model into the user model. - Second, we do a straightforward visual rendering of the display-oriented plan object. For the moment this is slightly overkill since there's only one rendering path, but it does give us the benefit of letting the counts be derived from the same data as the full detailed diff, ensuring that they'll stay consistent. Later we may choose to have other UIs for plans, such as a machine-readable output intended to drive a web UI. In that case, we'd want the web UI to consume a serialization of the _display-oriented_ plan so that it doesn't need to re-implement all of these UI special cases. This introduces to core a new diff action type for "refresh". Currently this is used _only_ in the UI layer, to represent data source reads. Later it would be good to use this type for the core diff as well, to improve consistency, but that is left for another day to keep this change focused on the UI.	9 years ago
Martin Atkins	0dc6d97a37	command/format: minor adjustments to plan rendering ... This change makes various minor adjustments to the rendering of plans in the output of "terraform plan": - Resources are identified using the standard resource address syntax, rather than exposing the legacy internal representation used in the module diff resource keys. This fixes #8713. - Subjectively, having square brackets in the addresses made it look more visually "off" when the same name but with different indices were shown together with differing-length "symbols", so the symbols are now all padded and right-aligned to three characters for consistent layout across all operations. - The -/+ action is now more visually distinct, using several different colors to help communicate what it will do and including a more obvious "(new resource required)" marker to help draw attention to this not being just an update diff. This fixes #15350. - The resources are now sorted in a manner that sorts index [10] after index [9], rather than after index [1] as we did before. This makes it easier to scan the list and avoids the common confusion where it seems that there are only 10 items when in fact there are 11-20 items with all the tens hiding further up in the list.	9 years ago
