Martin Atkins	248cf7f13a	main: A slightly more compact presentation of the main help text ... This just reduces the amount of space between different elements on in the main help output from four columns to two. The main motivation here was to give some of the longer command descriptions a little more horizontal breathing room, but subjectively I also find the tighter column gutters easier to scan. Others may disagree, of course.	6 years ago
Martin Atkins	9665901e8e	main: Emphasize only the primary workflow commands in our help ... A long time ago we introduced this separation between "common commands" and "all other commands", but over the intervening years we've not really done a good job of classifying new commands we've added and so by default most of them ended up being classified as "common". In the interests of making this output more useful for those getting started, this switches the two categories so that "Main commands" is now the curated list, and "all other commands" is the bucket for everything else. The intent here is that the "main commands" are the ones users are likely to try as part of their initial learning of Terraform, while the other commands are for less common situations where the user is more likely to learn about a specific command in some other context, like a tutorial about a special situation. The "main commands" are also now ordered by the sequence users will typically run them in, rather than alphabetical order. That's a subjective readability tradeoff, but I think as long as the list stays relatively short (which it should) it's still relatively easy to scan and find a particular command in the shortlist.	6 years ago
Martin Atkins	f44265e59e	main: Hide several commands from our help ... These are commands that either no longer do anything aside from emitting an error message or are just backward-compatibility aliases for other commands. This generalizes our previous situation where we were specifically hiding "internal-plugin", and does so in a way that fixes the long-standing cosmetic bug that the column width in the help output was chosen based on the hidden command "internal-plugin", which is unfortunately also the longest command in our command set.	6 years ago
Martin Atkins	efe78b2910	main: new global option -chdir ... This new option is intended to address the previous inconsistencies where some older subcommands supported partially changing the target directory (where Terraform would use the new directory inconsistently) where newer commands did not support that override at all. Instead, now Terraform will accept a -chdir command at the start of the command line (before the subcommand) and will interpret it as a request to direct all actions that would normally be taken in the current working directory into the target directory instead. This is similar to options offered by some other similar tools, such as the -C option in "make". The new option is only accepted at the start of the command line (before the subcommand) as a way to reflect that it is a global command (not specific to a particular subcommand) and that it takes effect _before_ executing the subcommand. This also means it'll be forced to appear before any other command-specific arguments that take file paths, which hopefully communicates that those other arguments are interpreted relative to the overridden path. As a measure of pragmatism for existing uses, the path.cwd object in the Terraform language will continue to return the _original_ working directory (ignoring -chdir), in case that is important in some exceptional workflows. The path.root object gives the root module directory, which will always match the overriden working directory unless the user simultaneously uses one of the legacy directory override arguments, which is not a pattern we intend to support in the long run. As a first step down the deprecation path, this commit adjusts the documentation to de-emphasize the inconsistent old command line arguments, including specific guidance on what to use instead for the main three workflow commands, but all of those options remain supported in the same way as they were before. In a later commit we'll make those arguments produce a visible deprecation warning in Terraform's output, and then in an even later commit we'll remove them entirely so that -chdir is the single supported way to run Terraform from a directory other than the one containing the root module configuration.	6 years ago
Chris Marchesi	04d00cec9f	help: Make version and help flags consistent ... These flags are presented as POSIX/GNU-style long-form flags (double-dash), whereas the rest of our CLI flags as seen in sub-commands are presented as single-dash options. While both work in both cases (on part of the flag package allowing double dashes as well), we converge around the single-dash form, so the basic help text here should be consistent.	8 years ago
Martin Atkins	fef5727904	Remind future maintainers to update the docs when changing CLI usage ... We have a copy of the output from running just "terraform" in a page on the website. It doesn't necessarily need to be kept 100% up to date, since users can always run the command to get the result from the horses mouth, but it's nice to keep it somewhat up-to-date to reduce use confusion.	10 years ago

Mitchell Hashimoto	d1b46e99bd	Add `terraform state list` command ... This introduces the terraform state list command to list the resources within a state. This is the first of many state management commands to come into 0.7. This is the first command of many to come that is considered a "plumbing" command within Terraform (see "plumbing vs porcelain": http://git.661346.n2.nabble.com/what-are-plumbing-and-porcelain-td2190639.html). As such, this PR also introduces a bunch of groundwork to support plumbing commands. The main changes: - Main command output is changed to split "common" and "uncommon" commands. - mitchellh/cli is updated to support nested subcommands, since terraform state list is a nested subcommand. - terraform.StateFilter is introduced as a way in core to filter/search the state files. This is very basic currently but I expect to make it more advanced as time goes on. - terraform state list command is introduced to list resources in a state. This can take a series of arguments to filter this down. Known issues, or things that aren't done in this PR on purpose: - Unit tests for terraform state list are on the way. Unit tests for the core changes are all there.	10 years ago
