🔍 问题说明

Poorly documented large function

This rule finds large functions that have too few comment lines. Documentation becomes more important as a function becomes more complex, and a lack of documentation makes it harder to maintain.

Recommendation

Add comments to document the purpose of the function. Large, complex functions in particular require detailed documentation, not only because they are harder to understand, but the process of documentation may reveal that the function could be split into smaller, more cohesive functions.

🤖 AI 修复思路

The best fix is to add clear, structured comments inside ModuleHelp_Translation_Convert so the function’s internal flow is documented without altering logic.
Specifically in XEngine_Source/XEngine_ModuleHelp/ModuleHelp_Language/ModuleHelp_Language.cpp, around the function starting at line 42:

• Add a short multi-line comment at function start describing:
  • what conversion it performs,
  • that it writes to ptszTranslationType,
  • and that it updates ModuleHelp_IsErrorOccur / ModuleHelp_dwErrorCode on failure.
• Add inline comments before key phases:
  • input validation,
  • language enum → provider code mapping,
  • unsupported-type handling (if present later in the function).
• Keep all existing branches and return behavior unchanged.

No new methods, imports, or dependencies are needed.
