Code Review

This pull request refactors the documentation generation script to add source code blocks for methods, not just top-level classes and functions. The changes are well-structured, breaking down the logic into smaller helper functions and using a two-pass approach to inject the source code into the generated Markdown. This is a great improvement. My feedback focuses on improving error handling by replacing broad except Exception clauses with more specific exception types, which will make the code more robust and easier to debug.

[gemini-code-assist]

Catching a broad Exception can hide unrelated errors. It's better to be specific. In this case, obj might be missing attributes, so AttributeError would be more appropriate.

Suggested change

	except Exception:
	return md
	return None, None, None
	except AttributeError:
	return None, None, None

[gemini-code-assist]

Using a broad except Exception can mask unexpected issues. For file I/O, it's better to catch specific exceptions like IOError or FileNotFoundError.

Suggested change

	except Exception:
	return None, None, None
	except (IOError, FileNotFoundError):
	return None, None, None

[gemini-code-assist]

To avoid hiding potential bugs, it's best to catch specific exceptions instead of a general Exception. Here, AttributeError would be more suitable if a member object is missing expected attributes like kind, lineno, or endlineno.

Suggested change

	except Exception:
	continue
	except AttributeError:
	continue
