Jesse Szwedko	0fbd72a355	Add some basic math interpolation functions ... Support the following math functions for interpolation: * ceil * floor * max * min Fixes #7409	10 years ago
James Nugent	47bce79b29	core: Add zipmap interpolation function ... This commit adds a new interpolation function, zipmap, which produces a map given a list of string keys and a list of values of the same length as the list of keys. The name comes from the same operation in Clojure (and likely other functional langauges).	10 years ago
Gustavo	5910e3b8af	Adds ‘tittle’ built-in function. (#9087) ... The tittle function returns a copy of the string with the first characters of all the words capitalized.	10 years ago
James Bardin	39bbbb8da6	Add merge interpolation function ... Add a `merge` interpolation function, which merges any number of maps. Duplicate keys are OK, with the last write winning.	10 years ago
James Bardin	c9e1522103	Use HIL to limit concat to ast.TypeList ... we can remove some type checks in the concat function	10 years ago
James Bardin	c15c0eb0cb	Disallow strings as arguments to concat ... The concat interpolation function now only accepts list arguments. Strings are no longer supported, for concatenation or appending to lists. All arguments must be a list, and single elements can be promoted with the `list` interpolation function.	10 years ago
Paul Hinze	88030764ff	config: Audit all interpolation functions for list/map behavior ... - `distinct()` - error on non-flat lists - `element()` - error on non-flat lists - `join()` - error on non-flat lists - `length()` - support maps - `lookup()` - error on non-flat maps - `values()` - error on non-flat maps	10 years ago
Paul Hinze	1425b34562	config: Add map() interpolation function ... * `map(key, value, ...)` - Returns a map consisting of the key/value pairs specified as arguments. Every odd argument must be a string key, and every even argument must have the same type as the other values specified. Duplicate keys are not allowed. Examples: * `map("hello", "world")` * `map("us-east", list("a", "b", "c"), "us-west", list("b", "c", "d"))`	10 years ago
James Bardin	8dcbc0b0a0	Add concat to accept lists of lists and maps ... This will allow the concat interpolation function to accept lists of lists, and lists of maps as well as strings. We still allow bare strings for backwards compatibility, but remove some of the old comment wording as it could cause confusion of this function with actual string concatenation. Since maps are now supported in the config, this removes the superfluous (and failing) TestInterpolationFuncConcatListOfMaps.	10 years ago
James Bardin	2bd7cfd5fe	Expand list interpolation to lists and maps ... Allow lists and maps within the list interpolation function via variable interpolation. Since this requires setting the variadic type to TypeAny, we check for non-heterogeneous lists in the callback.	10 years ago
James Nugent	58dd41f3b1	core: Add list() interpolation function ... The list() interpolation function provides a way to add support for list literals (of strings) to HIL without having to invent new syntax for it and modify the HIL parser. It presents as a function, thus: - list() -> [] - list("a") -> ["a"] - list("a", "b") -> ["a", "b"] Thanks to @wr0ngway for the idea of this approach, fixes #7460.	10 years ago
James Nugent	8403a465bc	core: Add test and fix for element with empty list ... The incldued test previously caused a panic, it now returns an error message explaining the issue.	10 years ago
James Nugent	4b6a632246	core: Rename uniq -> distinct and add docs	10 years ago
Jan Schumann	df3e017f6c	fix #7106	10 years ago
Paul Hinze	9bc980f569	core: Fix panic on concat() w/ list of nonprimitives ... The `concat()` interpolation function does not yet support types other than strings / lists of strings. Make it an error message instead of a panic when a list of non-primitives is supplied. Fixes the panic in #7030	10 years ago
James Nugent	578ff9569e	core: Add sort() interpolation function	10 years ago
David Adams	b5d1279107	Allow specifying a default value to lookup() ... Fixes #4474, where lookup() calls fail out the entire interpolation when the provided key value is not found in the map. This will allow using coalesce() along with lookup() to greatly improve module flexibility.	10 years ago
David Glasser	594ea105d8	config: support lists and maps in jsonencode ... For now we only support lists and maps whose values are strings, not deeply nested data.	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

José F. Romaniello	c8795b8565	Add signum interpolation function ... This function returns -1 for negative numbers, 0 for 0 and 1 for positive numbers. Useful when you need to set a value for the first resource and a different value for the rest of the resources. Example: `${element(split(",", var.r53_failover_policy), signum(count.index))}`	10 years ago
Matt Moyer	c17a6ceb2a	Add a sha256(...) interpolation function.	10 years ago
Paul Hinze	0739cf2348	provider/template: fix race causing panic in template_file ... The render code path in `template_file` was doing unsynchronized access to a shared mapping of functions in `config.Func`. This caused a race condition that was most often triggered when a `template_file` had a `count` of more than one, and expressed itself as a panic in the plugin followed by a cascade of "unexpected EOF" errors through the plugin system. Here, we simply turn the FuncMap from shared state into a generated value, which avoids the race. We do more re-initialization of the data structure, but the performance implications are minimal, and we can always revisit with a perf pass later now that the race is fixed.	10 years ago

Martin Atkins	ef161e1c1b	Various interpolation functions for CIDR range manipulation. ... These new functions allow Terraform to be used for network address space planning tasks, and make it easier to produce reusable modules that contain or depend on network infrastructure. For example: - cidrsubnet allows an aws_subnet to derive its CIDR prefix from its parent aws_vpc. - cidrhost allows a fixed IP address for a resource to be assigned within an address range defined elsewhere. - cidrnetmask provides the dotted-decimal form of a prefix length that is accepted by some systems such as routing tables and static network interface configuration files. The bulk of the work here is done by an external library I authored called go-cidr. It is MIT licensed and was implemented primarily for the purpose of using it within Terraform. It has its own unit tests and so the unit tests within this change focus on simple success cases and on the correct handling of the various error cases.	11 years ago

Martin Atkins	0b85d35e87	Rename base64enc/dec to encode/decode. ... There isn't any precedent for abbreviating words in the interpolation function names, and it may not be clear to all users what "enc" and "dec" are short for, so instead we'll prefer to spell out the whole words for improved readability.	11 years ago

Paul Hinze	c95f21cec1	config: make formatlist work on lists of length 1 ... removes treat-lists-as-scalar special casing for formatlist /cc @radeksimko fixes #2240	11 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
