James Nugent	681d94ae20	core: Allow lists and maps as variable overrides ... Terraform 0.7 introduces lists and maps as first-class values for variables, in addition to string values which were previously available. However, there was previously no way to override the default value of a list or map, and the functionality for overriding specific map keys was broken. Using the environment variable method for setting variable values, there was previously no way to give a variable a value of a list or map. These now support HCL for individual values - specifying: TF_VAR_test='["Hello", "World"]' will set the variable `test` to a two-element list containing "Hello" and "World". Specifying TF_VAR_test_map='{"Hello = "World", "Foo" = "bar"}' will set the variable `test_map` to a two-element map with keys "Hello" and "Foo", and values "World" and "bar" respectively. The same logic is applied to `-var` flags, and the file parsed by `-var-files` ("autoVariables"). Note that care must be taken to not run into shell expansion for `-var-` flags and environment variables. We also merge map keys where appropriate. The override syntax has changed (to be noted in CHANGELOG as a breaking change), so several tests needed their syntax updating from the old `amis.us-east-1 = "newValue"` style to `amis = "{ "us-east-1" = "newValue"}"` style as defined in TF-002. In order to continue supporting the `-var "foo=bar"` type of variable flag (which is not valid HCL), a special case error is checked after HCL parsing fails, and the old code path runs instead.	10 years ago

Paul Hinze	97acccd3ed	core: targeted operations ... Add `-target=resource` flag to core operations, allowing users to target specific resources in their infrastructure. When `-target` is used, the operation will only apply to that resource and its dependencies. The calculated dependencies are different depending on whether we're running a normal operation or a `terraform destroy`. Generally, "dependencies" refers to ancestors: resources falling _before_ the target in the graph, because their changes are required to accurately act on the target. For destroys, "dependencies" are descendents: those resources which fall _after_ the target. These resources depend on our target, which is going to be destroyed, so they should also be destroyed.	11 years ago
