Alisdair McDiarmid	09d8355f43	command: Add experimental concise diff renderer ... When rendering a diff between current state and projected state, we only show resources and outputs which have changes. However, we show a full structural diff for these values, which includes all attributes and blocks for a changed resource or output. The result can be a very long diff, which makes it difficult to verify what the changed fields are. This commit adds an experimental concise diff renderer, which suppresses most unchanged fields, only displaying the most relevant changes and some identifying context. This means: - Always show all identifying attributes, initially defined as `id`, `name`, and `tags`, even if unchanged; - Only show changed, added, or removed primitive values: `string`, `number`, or `bool`; - Only show added or removed elements in unordered collections and structural types: `map`, `set`, and `object`; - Show added or removed elements with any surrounding unchanged elements for sequence types: `list` and `tuple`; - Only show added or removed nested blocks, or blocks with changed attributes. If any attributes, collection elements, or blocks are hidden, a count is kept and displayed at the end of the parent scope. This ensures that it is clear that the diff is only displaying a subset of the resource. The experiment is currently enabled by default, but can be disabled by setting the TF_X_CONCISE_DIFF environment variable to 0.	6 years ago
Mitchell Hashimoto	864c79396d	terraform: default shadow to false ... To avoid chasing down issues like #11635 I'm proposing we disable the shadow graph for end users now that we have merged in all the new graphs. I've kept it around and default-on for tests so that we can use it to test new features as we build them. I think it'll still have value going forward but I don't want to hold us for making it work 100% with all of Terraform at all times. I propose backporting this to 0-8-stable, too.	9 years ago
Mitchell Hashimoto	09242fab09	terraform: remove legacy graph builder	9 years ago
Mitchell Hashimoto	785cc7b78a	terraform: default new graphs on, old graphs behind -Xlegacy-graph ... This turns the new graphs on by default and puts the old graphs behind a flag `-Xlegacy-graph`. This effectively inverts the current 0.7.x behavior with the new graphs. We've incubated most of these for a few weeks now. We've found issues and we've fixed them and we've been using these graphs internally for awhile without any major issue. Its time to default them on and get them part of a beta.	10 years ago
Mitchell Hashimoto	af82be19ea	helper/experiment: a helper for setting, making experiments ... This creates a standard package and interface for defining, querying, setting experiments (`-X` flags). I expect we'll want to continue to introduce various features behind experimental flags. I want to make doing this as easy as possible and I want to make _removing_ experiments as easy as possible as well. The goal with this packge has been to rely on the compiler enforcing our experiment references as much as possible. This means that every experiment is a global variable that must be referenced directly, so when it is removed you'll get compiler errors where the experiment is referenced. This also unifies and makes it easy to grab CLI flags to enable/disable experiments as well as env vars! This way defining an experiment is just a couple lines of code (documented on the package).	10 years ago
