RemovedInSphinx90Warning: string paths passed to Sphinx image registration API #110
Description
Description
With Sphinx >= 8.2.3 and sphinxcontrib-drawio 0.0.17, building documentation emits repeated RemovedInSphinx90Warning during the image copying phase:
copying images... [ 62%] sphinx/environment/adapters/asset.py:19: RemovedInSphinx90Warning: Sphinx 9 will drop support for representing paths as strings. Use "pathlib.Path" or "os.fspath" instead.
while _StrPath(name) in self.env.original_image_uri:
sphinx/environment/adapters/asset.py:20: RemovedInSphinx90Warning: Sphinx 9 will drop support for representing paths as strings. Use "pathlib.Path" or "os.fspath" instead.
name = self.env.original_image_uri[_StrPath(name)]
Environment
- Python 3.12
- Sphinx 8.2.3
- sphinxcontrib-drawio 0.0.17
Expected behavior
No deprecation warnings during build.
Cause
It appears that sphinxcontrib-drawio registers images using string paths rather than pathlib.Path objects, which triggers Sphinx's deprecation warning ahead of the Sphinx 9 breaking change.
