Arthur Burkart	6ed47c7241	lang/funcs: Add "alltrue" function (#25656) ... This commit adds an `alltrue` function to Terraform configuration. A reason we might want this function is because it will enable more powerful custom variable validations. For example: ```hcl variable "amis" { type = list(object({ id = string })) validation { condition = (alltrue([ for a in var.amis : length(a.id) > 4 && substr(a.id, 0, 4) == "ami-" ])) error_message = "The ID of at least one AMI was invalid." } } ```	6 years ago
Alisdair McDiarmid	c7568ccceb	lang: Add test for jsonencode entity escaping ... The encoding/json package escapes some HTML-specific characters to prevent JSON from being misinterpreted when in the context of an HTML document. Terraform 0.11 used this behaviour, and to preserve backwards compatibility we are continuing to do so moving forward. This commit adds an explicit test to document that this is intentional, not a bug.	6 years ago

Noah Mercado	d4d8812afa	Feature: Sum Function (#24666) ... The sum function takes a list or set of numbers and returns the sum of those numbers.	6 years ago
James Goodhouse	25bfe7337b	lang: add setsubtract function (#23424) ... * add setdifference and setsubtract functions and docs * remove setdifference as it is not implemented correct in underlying lib * Update setintersection.html.md * Update setproduct.html.md * Update setunion.html.md	6 years ago
Martin Atkins	02576988c1	lang: "try" and "can" functions ... These are intended to make it easier to work with arbitrary data structures whose shape might not be known statically, such as the result of jsondecode(...) or yamldecode(...) of data from a separate system. For example, in an object value which has attributes that may or may not be set we can concisely provide a fallback value to use when the attribute isn't set: try(local.example.foo, "fallback-foo") Using a "try to evaluate" model rather than explicit testing fits better with the usual programming model of the Terraform language where values are normally automatically converted to the necessary type where possible: the given expression is subject to all of the same normal type conversions, which avoids inadvertently creating a more restrictive evaluation model as might happen if this were handled using checks like a hypothetical isobject(...) function, etc.	6 years ago

Martin Atkins	39e609d5fd	vendor: switch to HCL 2.0 in the HCL repository ... Previously we were using the experimental HCL 2 repository, but now we'll shift over to the v2 import path within the main HCL repository as part of actually releasing HCL 2.0 as stable. This is a mechanical search/replace to the new import paths. It also switches to the v2.0.0 release of HCL, which includes some new code that Terraform didn't previously have but should not change any behavior that matters for Terraform's purposes. For the moment the experimental HCL2 repository is still an indirect dependency via terraform-config-inspect, so it remains in our go.sum and vendor directories for the moment. Because terraform-config-inspect uses a much smaller subset of the HCL2 functionality, this does still manage to prune the vendor directory a little. A subsequent release of terraform-config-inspect should allow us to completely remove that old repository in a future commit.	7 years ago
Martin Atkins	f84ab99b7d	lang/funcs: cidrsubnets function ... This is a companion to cidrsubnet that allows bulk-allocation of multiple subnet addresses at once, with automatic numbering. Unlike cidrsubnet, cidrsubnets allows each of the allocations to have a different prefix length, and will pack the networks consecutively into the given address space. cidrsubnets can potentially create more complicated addressing schemes than cidrsubnet alone can, because it's able to take into account the full set of requested prefix lengths rather than just one at a time.	7 years ago

Brian Flad	af7f6ef441	lang/funcs: Update fileset() function to include path as separate first argument, automatically trim the path argument from results, and ensure results are always canonical with forward slash path separators ... Reference: https://github.com/hashicorp/terraform/pull/22523#pullrequestreview-279694703 These changes center around better function usability and consistency with other functions. The function has not yet been released, so these breaking changes can be applied safely.	7 years ago
Brian Flad	d48d9ed766	lang/funcs: Add fileset function ... Reference: https://github.com/hashicorp/terraform/issues/16697 Enumerates a set of regular file names from a given glob pattern. Implemented via the Go stdlib `path/filepath.Glob()` functionality. Notably, stdlib does not support `**` or `{}` extended patterns. See also: https://github.com/golang/go/issues/11862 To support the extended glob patterns, it will require adding a dependency on a third party library or adding our own matching code.	7 years ago
Martin Atkins	135afaeb9c	lang: "regex" and "regexall" functions ... These existing upstream cty functions allow matching strings against regular expression patterns, which can be useful if you need to consume a non-standard string format that Terraform doesn't (and can't) have a built-in function for.	7 years ago
Andreas Sommer	042aead714	lang/funcs: add "abspath" function (#21409)	7 years ago
Lars Eric Scheidler	aa07806bfc	lang/funcs: New "uuidv5" function ... This generates name-based uuids, rather than pseudorandom uuids as with the "uuid" function.	7 years ago
Martin Atkins	382e1ca821	lang: yamldecode and yamlencode functions ... These follow the same principle as jsondecode and jsonencode, but use YAML instead of JSON. YAML has a much more complex information model than JSON, so we can only support a subset of it during decoding, but hopefully the subset supported here is a useful one. Because there are many different ways to _generate_ YAML, the yamlencode function is forced to make some decisions, and those decisions are likely to affect compatibility with other real-world YAML parsers. Although the format here is intended to be generic and compatible, we may find that there are problems with it that'll we'll want to adjust for in a future release, so yamlencode is therefore marked as experimental for now until the underlying library is ready to commit to ongoing byte-for-byte compatibility in serialization. The main use-case here is met by yamldecode, which will allow reading in files written in YAML format by humans for use in Terraform modules, in situations where a higher-level input format than direct Terraform language declarations is helpful.	7 years ago
Martin Atkins	f9a73d48db	lang: "range" function ... This is similar to the function of the same name in Python, generating a sequence of numbers as a list that can then be used in other sequence-oriented operations. The primary use-case for it is to turn a count expressed as a number into a list of that length, which can then be iterated over or passed to a collection function to produce that number of something else, as shown in the example at the end of its documentation page.	7 years ago
Kristin Laemmert	30a924e162	lang/funcs: `matchkeys` - unify type for keys and searchset ... Added higher-level test for matchkeys to exercise mixing types in searchset. This had to be in the functions tests so the HCL auto conversion from tuple to list would occur.	7 years ago
Kristin Laemmert	b1d0b1383f	lang/funcs: remove sethaselement function and documentation (#21164) ... `contains` and `sethaselement` are effectively the same function, and `contains` works with `sets` thanks to automatic HCL conversion.	7 years ago
James Bardin	19bddee11b	more precise types handling in coalescelist ... coalescelist should accept lists and tuples, and return a dynamic types when the arguments are not homogeneous.	7 years ago
James Bardin	d186d3a490	update slice test	7 years ago
Kristin Laemmert	8520f4e4a5	* lang/funcs/flatten: accept sets and tuples, return tuples ... * lang/funcs: flatten should handle sets and tuples * flatten now returns a tuple	7 years ago
Kristin Laemmert	394cf7f25e	lang/funcs: add acc tests for functions (#21112) ... * lang/funcs: testing of functions through the lang package API The function-specific unit tests do not cover the HCL conversion that happens when the functions are called in a terraform configuration. For e.g., HCL converts sets to lists before passing it to the function. This means that we could not test passing a set in the function _unit_ tests. This adds a higher-level acceptance test, plus a check that every (pure) function has a test. * website/docs: update function documentation	7 years ago
