René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"bug: Inventory config 'base_url' no longer works","articleBody":"### Description of the bug\nWhen specifying an inventory with a `base_url` that is different from the `url`, the `base_url` is ignored after the `0.28.0` rework. The rendered cross-reference URL uses the `url` value, not the `base_url` value.\n\nThe issue is that the new `Inventory` dataclass in https://github.com/mkdocstrings/python/blob/main/src/mkdocstrings_handlers/python/_internal/config.py#L963-L992 has a `base` attribute, which is also returned in the `_config` property as `base`, and not `base_url`. However, the `load_inventory` method still expects a `base_url` keyword, but now gets `base=...` which is put into `**kwargs` and ignored.\n\n### Environment information\n```bash\npython -m mkdocstrings_handlers.python._internal.debug  # | xclip -selection clipboard\n```\n\n- __System__: Linux-6.11.0-21-generic-x86_64-with-glibc2.39\n- __Python__: cpython 3.12.3 (/home/stefan/salling/ml-utils-pipeline-new/.venv/bin/python)\n- __Environment variables__:\n- __Installed packages__:\n  - `mkdocstrings-python` v1.16.8\n\n### Additional context\nI'll be happy to make a PR fixing this, but I could use some help in figuring out how to add test(s) 🙂 \n","author":{"url":"https://github.com/connesy","@type":"Person","name":"connesy"},"datePublished":"2025-04-03T11:08:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/268/python/issues/268"}
