Mitchell Hashimoto	37c880c377	Update reflectwalk to fix failing tests As part of working on ResourceConfig.DeepCopy, Equal I updated reflectwalk (to fix some issues in the new functions) but this introduced more issues in other parts of Terraform. This update fixes those.	10 years ago
James Nugent	f49583d25a	core: support native list variables in config This commit adds support for native list variables and outputs, building up on the previous change to state. Interpolation functions now return native lists in preference to StringList. List variables are defined like this: variable "test" { # This can also be inferred type = "list" default = ["Hello", "World"] } output "test_out" { value = "${var.a_list}" } This results in the following state: ``` ... "outputs": { "test_out": [ "hello", "world" ] }, ... ``` And the result of terraform output is as follows: ``` $ terraform output test_out = [ hello world ] ``` Using the output name, an xargs-friendly representation is output: ``` $ terraform output test_out hello world ``` The output command also supports indexing into the list (with appropriate range checking and no wrapping): ``` $ terraform output test_out 1 world ``` Along with maps, list outputs from one module may be passed as variables into another, removing the need for the `join(",", var.list_as_string)` and `split(",", var.list_as_string)` which was previously necessary in Terraform configuration. This commit also updates the tests and implementations of built-in interpolation functions to take and return native lists where appropriate. A backwards compatibility note: previously the concat interpolation function was capable of concatenating either strings or lists. The strings use case was deprectated a long time ago but still remained. Because we cannot return `ast.TypeAny` from an interpolation function, this use case is no longer supported for strings - `concat` is only capable of concatenating lists. This should not be a huge issue - the type checker picks up incorrect parameters, and the native HIL string concatenation - or the `join` function - can be used to replicate the missing behaviour.	10 years ago
James Nugent	e57a399d71	core: Use native HIL maps instead of flatmaps This changes the representation of maps in the interpolator from the dotted flatmap form of a string variable named "var.variablename.key" per map element to use native HIL maps instead. This involves porting some of the interpolation functions in order to keep the tests green, and adding support for map outputs. There is one backwards incompatibility: as a result of an implementation detail of maps, one could access an indexed map variable using the syntax "${var.variablename.key}". This is no longer possible - instead HIL native syntax - "${var.variablename["key"]}" must be used. This was previously documented, (though not heavily used) so it must be noted as a backward compatibility issue for Terraform 0.7.	10 years ago

Paul Hinze	e88aeede9b	core: allow distinguishing between empty lists and strings Had to handle a lot of implicit leaning on a few properties of the old representation: * Old representation allowed plain strings to be treated as lists without problem (i.e. shoved into strings.Split), now strings need to be checked whether they are a list before they are treated as one (i.e. shoved into StringList(s).Slice()). * Tested behavior of 0 and 1 length lists in formatlist() was a side effect of the representation. Needs to be special cased now to maintain the behavior. * Found a pretty old context test failure that was wrong in several different ways. It's covered by TestContext2Apply_multiVar so I removed it.	11 years ago
Paul Hinze	7238b3b4af	core: encapsulate representation of StringList Now the only code that cares about how StringLists are represented lives inside string_list.go ...which gives us the ability to change it! :)	11 years ago
Paul Hinze	10b3abf405	config: introduce StringList to abstract over list hack This is the initial pure "all tests passing without a diff" stage. The plan is to change the internal representation of StringList to include a suffix delimiter, which will allow us to recognize empty and single-element lists.	11 years ago
