fmeum · web-flow · commit 3ebd927df0f4 · 2023-01-18T14:09:20.000-08:00
The runfiles library now canonically lives in rules_python and has been
updated multiple times since its original import from bazel_tools.

-#     from rules_python.python.runfiles import runfiles

-# in user code. This requires either adding a symlink to runfiles or copying

-# Both solutions are made more difficult by the fact that runfiles.py is not
-# directly exported by its package. We could try to get a handle on its File
-# object by unpacking the runfiles target's providers, but this seems hacky
-# and is probably more effort than it's worth. Also, it's not trivial to copy
-# files in a cross-platform (i.e. Windows-friendly) way.
-#
-# So instead, we just vendor in runfiles.py here.
