MkDocs renderer implementation.
|
|
|
|
This module defines the ``MkDocsRenderer`` class, which generates Markdown
|
|
documentation sources compatible with MkDocs Material and the mkdocstrings
|
|
plugin.
|
|
|
|
The renderer ensures a consistent documentation structure by:
|
|
|
|
- Creating a root ``index.md`` if one does not exist
|
|
- Generating package index pages automatically
|
|
- Linking child modules within parent package pages
|
|
- Optionally generating ``README.md`` from the root package docstring
