Skylib module containing utilities for Bazel modules and module extensions.
Wraps a WORKSPACE dependency macro into a module extension.
Example:
def rules_foo_deps(optional_arg = True): some_repo_rule(name = "foobar") http_archive(name = "bazqux") rules_foo_deps_ext = modules.as_extension(rules_foo_deps)
PARAMETERS
Name | Description | Default Value |
---|---|---|
macro | A WORKSPACE dependency macro, i.e., a function with no required parameters that instantiates one or more repository rules. | none |
doc | A description of the module extension that can be extracted by documentation generating tools. | None |
RETURNS
A module extension that generates the repositories instantiated by the given macro and also uses use_all_repos
to indicate that all of those repositories should be imported via use_repo
.
Return from a module extension that should have all its repositories imported via use_repo
.
Example:
def _ext_impl(module_ctx): some_repo_rule(name = "foobar") http_archive(name = "bazqux") return modules.use_all_repos(module_ctx) ext = module_extension(_ext_impl)
PARAMETERS
Name | Description | Default Value |
---|---|---|
module_ctx | The module_ctx object passed to the module extension's implementation function. | none |
RETURNS
An extension_metadata
object that, when returned from a module extension implementation function, specifies that all repositories generated by this extension should be imported via use_repo
. If the current version of Bazel doesn't support extension_metadata
, returns None
instead, which can safely be returned from a module extension implementation function in all versions of Bazel.
