Use of importlib.metadata breaks import when metadata is stripped #15
Description
Expected Behavior: Importing the module works without bundling Package Metadata in application
Actual Behavior: Stripping Package Metadata breaks imports
Cause:
The pattern of directly using importlib.metadata to set the version assumes that package metadata is included in the location where the package is being used. As a result, this breaks when using slimmed down deployment artifacts, as package metadata is not bundled. I have seen a standard approach to this to be to wrap this self-referential version within a try/except block, e.g.
try:
__version__ = version("annotated-doc")
except Exception:
__version__ = "unknown"
