Martin Atkins	d859bacbdd	configs/configload: InitDirFromModule ... This will provide the functionality of "terraform init -from-module=...", which uses the contents of a given module to populate the working directory. This mechanism is intended for installing e.g. examples from Terraform Registry or elsewhere. It's not fully-general since it can't reasonably install a module from a subdir that refers up to a parent directory, but that isn't an issue for all reasonable uses of this option.	8 years ago
Martin Atkins	74afcb4a7f	configs/configload: some loaders can't install modules ... Originally the hope was to use the afero filesystem abstraction for all loader operations, but since we install modules using go-getter we cannot (without a lot of refactoring) support vfs for installation. The vfs use-case is for reading configuration from plan zip files anyway, and so we have no real reason to support installation into a vfs. For now at least we will just add the possibility that a loader might not be install-capable. At the moment we have no non-install-capable loaders, but we'll add one later once we get to loading configuration from plan files.	8 years ago
Martin Atkins	59939cf320	configs/configload: installation from registry and go-getter ... Unlike the old installer in config/module, this uses new-style installation directories that include the static module path so that paths we show in diagnostics will be more meaningful to the user. As before, we retrieve the entire "package" associated with the given source string, rather than any given subdirectory directly, because the retrieved module may contain ../ references into parent directories which must be resolvable after extraction.	8 years ago
Martin Atkins	7feef98517	configs/configload: installation of local modules ... Enough of the InstallModules method to install local modules (those with relative paths). "Install" is actually a bit of an exaggeration for these since we actually just record them in our manifest after verifying that the source directory exists. This is a change of behavior relative to the old module installer since we no longer create a symlink to the module directory inside the .terraform/modules directory. Instead, we record the module's true location in our manifest so that the loader will find it later. The use of a symlink here predated the manifest file. Now that we have a manifest file the symlinks are redundant. Using the "natural" location of the module leads to more helpful error messages, since we'll refer to the module path as the user expects it, rather than to an internal alias.	8 years ago
