having a bit of a crisis

using platforms to model build environments is broken because of how strategies interact with platforms

bzlmod is conceptually pretty excellent but still has tons of warts and weird limitations that require lots of creative workarounds

We couldn’t find that file to show.

	"""Workarounds for https://github.com/bazelbuild/bazel/issues/19055."""

	# TODO(build, bazel, blzmod): if new APIs are introduced resolving this issue:
	# https://github.com/bazelbuild/bazel/issues/19055, use them in lieu of this
	# function.
	def get_sibling_repo_in_module_extension(rctx, repo_name):
	"""Gets the _canonical_ name for a sibling repo in the module extension.

	## Background

	"""Starlark version of `new_local_repository` for module extensions.

	Currently `native.new_local_repository` cannot be called from Bazel module
	extensions: https://github.com/bazelbuild/bazel/issues/15412

	The plan is to eventually "starlark-ify" this rule:
	- https://docs.google.com/document/d/17RZKMuMjAIgNfFdrsLhqNsMTQDSS-BBA-S-fCSBPV7M/edit
	- https://github.com/bazelbuild/bazel/issues/18285

	In the interim we've got our own Starlark-native `new_local_repository`

	"""Helper functions for repository rules that ensure labels are well-formed.

	Labels constructed and used within repository rules do not have their name (the
	part after `:`) checked against the package structure of the repo they point to;
	they are allowed to refer to source artifacts via paths that do not respect the
	package structure or visibility.

	For example, for a source file that lives at `@foo//bar/baz:some/file/path`, all
	of the following — when passed to repository context functions like `rctx.path`
	or `rctx.read` — will refer to the file, without error:

	Meant to be used together with this Bazel fork:
