Optimize Path Handling to Improve Code Compatibility and Maintainability

[lcolok]

优化路径处理逻辑，提升代码兼容性和可维护性

问题背景

在使用 ComfyUI-to-Python-Extension 导出工作流为 Python 代码时发现，导出的代码无法正确执行。原因是原有代码通过 __main__ 计算 extensions 路径，这种方式依赖于执行文件的位置。当导出的 Python 文件在其他位置运行时，就会计算出错误的路径。

改动内容

• 使用 ComfyUI 官方的 folder_paths 模块替代自定义路径计算
• 移除对 __main__ 的依赖，改用 folder_paths.base_path 获取根路径
• 优化目录创建逻辑，使用 os.makedirs 提供更可靠的目录创建

改进优势

• 立即解决：修复 ComfyUI-to-Python-Extension 导出代码的执行问题
• 长期可维护：依赖 ComfyUI 官方模块，随 ComfyUI 升级自动维护
• 更好兼容性：支持未来可能出现的更多复杂运行环境
• 代码质量：遵循 ComfyUI 最佳实践，提高代码可维护性

测试验证

• 基础功能和导出代码执行测试通过
• 向后兼容，无需用户调整

简单但前瞻性的改动，既解决当前问题，又为未来扩展打好基础。

Optimize Path Handling to Improve Code Compatibility and Maintainability

Background

Issue discovered when using ComfyUI-to-Python-Extension to export workflows as Python code. The original code calculates extensions path via __main__, which depends on execution file location. This causes path resolution errors when exported Python files are run from different locations.

Changes

• Replace custom path calculation with ComfyUI's official folder_paths module
• Remove __main__ dependency, use folder_paths.base_path for root path resolution
• Optimize directory creation with os.makedirs for more reliable handling

Benefits

• Immediate Fix: Resolve execution issues with ComfyUI-to-Python-Extension exported code
• Long-term Maintainability: Rely on ComfyUI's official module that updates with ComfyUI versions
• Better Compatibility: Support for future complex runtime environments
• Code Quality: Follow ComfyUI best practices for better maintainability

Testing

• Basic functionality and exported code execution verified
• Backward compatible, no user adjustments needed

A simple yet forward-looking change that not only solves current issues but also lays groundwork for future extensibility.
