Alisdair McDiarmid	6375c6ce6b	Merge pull request #27787 from hashicorp/alisdair/command-views-state-locker ... clistate: Update clistate.Locker for command views	5 years ago
Alisdair McDiarmid	0aa227e0e3	cli: Fix misapplied terminal colors on run logs ... Due to calling the Colorize function with the full string instead of the format string, plan/apply logs which include resource instance keys or IDs which happen to match color formatting would be rendered incorrectly. This commit fixes this by only colorizing the known-safe format string. We also add full test coverage for the UI hook, although only one of the hooks is tested for this color bugfix due to verbosity of the test. We also add the bold coloring to the provisioner output prefix, which seems to have been an oversight.	5 years ago
Alisdair McDiarmid	1ae3d30383	Merge pull request #27760 from hashicorp/alisdair/command-views-ui-hook ... cli: Migrate Terraform UI hook to command views	5 years ago
Alisdair McDiarmid	96cf29111d	views: Expand test coverage for views.Output ... Now that the view code is separated, we can increase test coverage in unit tests. This commit moves some tests from the command package which were testing only view code, and adds more new test cases.	5 years ago
Alisdair McDiarmid	2d1976bbda	clistate: Update clistate.Locker for command views ... The clistate package includes a Locker interface which provides a simple way for the local backend to lock and unlock state, while providing feedback to the user if there is a delay while waiting for the lock. Prior to this commit, the backend was responsible for initializing the Locker, passing through direct access to the cli.Ui instance. This structure prevented commands from implementing different implementations of the state locker UI. In this commit, we: - Move the responsibility of creating the appropriate Locker to the source of the Operation; - Add the ability to set the context for a Locker via a WithContext method; - Replace the Locker's cli.Ui and Colorize members with a StateLocker view; - Implement views.StateLocker for human-readable UI; - Update the Locker interface to return detailed diagnostics instead of errors, reducing its direct interactions with UI; - Add a Timeout() method on Locker to allow the remote backend to continue to misuse the -lock-timeout flag to cancel pending runs. When an Operation is created, the StateLocker field must now be populated with an implementation of Locker. For situations where locking is disabled, this can be a no-op locker. This change has no significant effect on the operation of Terraform, with the exception of slightly different formatting of errors when state locking or unlocking fails.	5 years ago
Alisdair McDiarmid	a7b7cd29fc	cli: Migrate Terraform UI hook to command views ... Move the code which renders Terraform hook callbacks as UI into the views package, backed by a views.View instead of a cli.Ui. Update test setup accordingly. To allow commands to control this hook, we add a hooks member on the backend Operation struct. This supersedes the hooks in the Terraform context, which is not directly controlled by the command logic. This commit should not change how Terraform works, and is refactoring in preparation for more changes which move UI code out of the backend.	5 years ago

Alisdair McDiarmid	57879bfb71	cli: Add global view arguments parser ... Rather than modifying and relying on the existing Meta.process argument extractor, we can more clearly handle global CLI flags using a separate parser step. This allows us to explicitly configure the view in the command.	5 years ago
Alisdair McDiarmid	c5a6aa31d3	cli: Add initial command views abstraction ... Terraform supports multiple output formats for several sub-commands. The default format is user-readable text, but many sub-commands support a `-json` flag to output a machine-readable format for the result. The output command also supports a `-raw` flag for a simpler, scripting- focused machine readable format. This commit adds a "views" abstraction, intended to help ensure consistency between the various output formats. This extracts the render specific code from the command package, and moves it into a views package. Each command is expected to create an interface for its view, and one or more implementations of that interface. By doing so, we separate the concerns of generating the sub-command result from rendering the result in the specified output format. This should make it easier to ensure that all output formats will be updated together when changes occur in the result-generating phase. There are some other consequences of this restructuring: - Views now directly access the terminal streams, rather than the now-redundant cli.Ui instance; - With the reorganization of commands, parsing CLI arguments is now the responsibility of a separate "arguments" package. For now, views are added only for the output sub-command, as an example. Because this command uses code which is shared with the apply and refresh commands, those are also partially updated.	5 years ago
