Martin Atkins	f302747077	website: Additional explanation for cidrsubnet function ... Some users are not accustomed to thinking of IP addresses in a bitwise fashion, so the hope here is to give enough of an introduction to that way of thinking for the reader to understand what the "newbits" and "netnum" arguments represent.	7 years ago
Nick Fagerlund	428a2c05e7	website: Expand output values docs (#20790) ... For 0.11 I just specified the naming rules; for 0.12, I added some info about referencing values and tightened up the layout of the optional arguments. This commit also syncs up descriptions of `depends_on`.	7 years ago

Martin Atkins	096b1bb87b	lang/funcs: Port the "reverse" function from the old functions set ... This has the same functionality as the "reverse" function that was implemented in the "config" package, but adapted to the new language type system.	7 years ago

Nick Fagerlund	34e90ff3c1	website: Fix broken links to modules/usage and modules/create ... As part of this, I'm copying the entire text of the 0.12 docs/configuration/modules.html page into docs/configuration-0-11/modules.html — some of the 0.11 pages needed to be able to link to the moved content, I didn't want to jump versions jarringly, and a close reading didn't reveal anything in there that's inaccurate for 0.11.	7 years ago

Martin Atkins	36bb9b462c	website: "for" expression examples to use canonical formatting ... The "terraform fmt" command produces a different canonical form than we were showing in our examples here. Our examples should always reflect the conventions applied by "terraform fmt" to avoid confusion. (This particular decision is a pragmatic one because the formatter design needs to use the same rules for the colon in the ? : conditional operator as for the colon in "for" expressions.)	7 years ago
Martin Atkins	0a9959cbe4	website: References to Resource Attributes ... Since references to attributes of resources are by far the most common reference type, and the mapping of resource type config to the attributes is not always obvious, here we give some real examples of patterns for accessing different configuration constructs within resource blocks along with the resource type's exported attributes. Since we don't have any real examples of labelled nested blocks yet (the current SDK doesn't support them) I've included a hypothetical example for now just to establish the patterns around them in preparation for beginning to introduce them as we roll out this feature in the SDK.	7 years ago
Martin Atkins	9336c7fba3	website: Revamped module-authoring docs for Terraform v0.12 ... As well as some general consolidation and reorganizing, this also includes some updated advice for making the best use of new Terraform v0.12 features to create infrastructure building-blocks. In particular, the "Module Usage" documentation is now consolidated into the configuration section in order to bring all of our general language documentation together, and the top-level "Modules" section is now primarily focused on module _authors_ as an audience, covering topics such as publishing modules and designing them for reuse.	7 years ago
Kristin Laemmert	21f6e3dffd	Mildwonkey/012 docs updated (#20542) ... * docs: update plan command documentation. Fixes #19235 * docs: added a missing reserved variable name. Fixes #19159. * website: add note that resource names cannot start with a number * website: add some notes to the 0.12 upgrade guide	7 years ago

Martin Atkins	954d38e870	lang: New file-hashing functions ... In prior versions, we recommended using hash functions in conjunction with the file function as an idiom for detecting changes to upstream blobs without fetching and comparing the whole blob. That approach relied on us being able to return raw binary data from file(...). Since Terraform strings pass through intermediate representations that are not binary-safe (e.g. the JSON state), there was a risk of string corruption in prior versions which we have avoided for 0.12 by requiring that file(...) be used only with UTF-8 text files. The specific case of returning a string and immediately passing it into another function was not actually subject to that corruption risk, since the HIL interpreter would just pass the string through verbatim, but this is still now forbidden as a result of the stricter handling of file(...). To avoid breaking these use-cases, here we introduce variants of the hash functions a with "file" prefix that take a filename for a disk file to hash rather than hashing the given string directly. The configuration upgrade tool also now includes a rule to detect the documented idiom and rewrite it into a single function call for one of these new functions. This does cause a bit of function sprawl, but that seems preferable to introducing more complex rules for when file(...) can and cannot read binary files, making the behavior of these various functions easier to understand in isolation.	7 years ago
Martin Atkins	2f8f7d6f4d	lang/funcs: Type conversion functions ... It's not normally necessary to make explicit type conversions in Terraform because the language implicitly converts as necessary, but explicit conversions are useful in a few specialized cases: - When defining output values for a reusable module, it may be desirable to force a "cleaner" output type than would naturally arise from a computation, such as forcing a string containing digits into a number. - Our 0.12upgrade mechanism will use some of these to replace use of the undocumented, hidden type conversion functions in HIL, and force particular type interpretations in some tricky cases. - We've found that type conversion functions can be useful as _temporary_ workarounds for bugs in Terraform and in providers where implicit type conversion isn't working correctly or a type constraint isn't specified precisely enough for the automatic conversion behavior. These all follow the same convention of being named "to" followed by a short type name. Since we've had a long-standing convention of running all the words together in lowercase in function names, we stick to that here even though some of these names are quite strange, because these should be rarely-used functions anyway.	7 years ago
Martin Atkins	da51e72cbb	lang/functions: set functions from cty ... The sethaselement, setintersection, and setunion functions are defined in the cty stdlib. Making them available in Terraform will make it easier to work with sets, and complement the currently-Terraform-specific setproduct function. In the long run setproduct should probably move into the cty stdlib too, but since it was submitted as a Terraform function originally we'll leave it here now for simplicity's sake and reorganize later.	7 years ago
Martin Atkins	edb5f82de1	lang/funcs: Convert the "setproduct" function to the new approach ... In our new world it produces either a set of a tuple type or a list of a tuple type, depending on the given argument types. The resulting collection's element tuple type is decided by the element types of the given collections, allowing type information to propagate even if unknown values are present.	7 years ago
Martin Atkins	d0e6a4c69a	lang: Add "formatdate" function ... We missed this one on a previous pass of bringing in most of the cty stdlib functions. This will resolve #17625 by allowing conversion from Terraform's conventional RFC 3339 timestamps into various other formats.	7 years ago
Martin Atkins	c753df6a93	lang/funcs: templatefile function ... This function is similar to the template_file data source offered by the template provider, but having it built in to the language makes it more convenient to use, allowing templates to be rendered from files anywhere an inline template would normally be allowed: user_data = templatefile("${path.module}/userdata.tmpl", { hostname = format("petserver%02d", count.index) }) Unlike the template_file data source, this function allows values of any type in its variables map, passing them through verbatim to the template. Its tighter integration with Terraform also allows it to return better error messages with source location information from the template itself. The template_file data source was originally created to work around the fact that HIL didn't have any support for map values at the time, and even once map support was added it wasn't very usable. With HCL2 expressions, there's little reason left to use a data source to render a template; the only remaining reason left to use template_file is to render a template that is constructed dynamically during the Terraform run, which is a very rare need.	7 years ago

Nick Fagerlund	d2abdc23ac	website: Structural edit of configuration language docs ... This commit is a wide-ranging set of edits to the pages under /docs/configuration. Among other things, it - Separates style conventions out into their own page. - Separates type constraints and conversion info into their own page. - Conflates similar complex types a little more freely, since the distinction is only relevant when restricting inputs for a reusable module or resource. - Clarifies several concepts that confused me during edits.	7 years ago
Nick Fagerlund	7d5db9522f	website: Fix plugin path on Windows (#19423) ... ...and one other reference to the application data directory. Context: https://docs.microsoft.com/en-us/windows/desktop/shell/knownfolderid#folderid_roamingappdata In newer Windows versions, the folder accessible as `%APPDATA%` (and via various APIs) is actually at something like "documents and settings\user\application data\roaming", while earlier versions omit the "\roaming" part of the path. This means you can confuse people by referring to the "application data" directory by its human name, because "roaming" is the real application data directory, but it looks like a subdirectory of "application data". Thus, it's less confusing to just use the `%APPDATA%` variable, with the added benefit that you can copy and paste the path and it'll just work in most places.	8 years ago

Martin Atkins	60ad24229f	website: Link from Configuration index to Resource page ... Since the index page is long, by the time the reader reaches the end of it the relevant portion if the navigation is unlikely to be visible. To compensate for this, we'll link to the first sub-section and thus give the user an opportunity to notice the navigation structure for the rest of the pages.	8 years ago
Martin Atkins	6549f24d88	website: Remove the "interpolation" docs page ... This has now been superseded by the expressions.html.md file in the same directory. As part of deploying this, the former URL for this page must be redirected to the expressions page to retain a target for any existing links on third-party sites.	8 years ago

Martin Atkins	a6749f9efc	website: Expand documentation of Override Files ... This kinda-weird feature was previously quite severely under-documented in terms of exactly what effect it has. This new documentation for it first attempts to frame it as something that should be rarely used, and then explains in more detail exactly how it behaves for different top-level block types within the configuration.	8 years ago
Martin Atkins	b3239e8f1f	website: Update the "Terraform Settings" page for new style ... As part of revamping the "Configuration" portion of the website for the v0.12 release, here we update the Terraform Settings page to use a similar "guide-like" writing style as the other updated pages in this section.	8 years ago
