@@ -463,3 +463,28 @@ OpenTofu will still extract the entire package to local disk, but will read
the module from the subdirectory. As a result, it is safe for a module in
a sub-directory of a package to use [a local path](#local-paths) to another
module as long as it is in the _same_ package.
## Support for Variable and Local Interpolation
As projects grow in complexity and requirements, it is prudent to consider using locals and variables in the module source and version fields.
Many organizations utilize the mono-repo pattern for modules:
```hcl
locals {
modules_repo = "github.com/myorg/tofu-modules/"
modules_version = "?ref=v1.20.4"
}
module "storage" {
source = "${local.modules_repo}/storage${local.modules_version}"
}
module "compute" {
source = "${local.modules_repo}/compute${local.modules_version}"
}
```
It is quite easy to then update the version for a patch release, or to switch to a fork of the repository.
:::note
The source and version fields may not contain any references to data in the state or provider defined functions. All value must be able to be resolved during `tofu init` before the state is available.

@@ -62,8 +62,7 @@ Module calls use the following kinds of arguments:
All modules **require** a `source` argument, which is a meta-argument defined by
OpenTofu. Its value is either the path to a local directory containing the
module's configuration files, or a remote module source that OpenTofu should
download and use. This value must be a literal string with no template
sequences; arbitrary expressions are not allowed. For more information on
download and use. For more information on
possible values for this argument, see [Module Sources](../../language/modules/sources.mdx).
The same source address can be specified in multiple `module` blocks to create
