VSCode中如何将extraPath内的模块添加至预加载模块优化补全速度？

Absolutely! Moving that bulky PyMEL completion module from extraPath to the preLoaded modules option is an excellent fix for your slow autocomplete issue—here’s the breakdown:

Why this works #

• The extraPath option tells your editor to scan and load the module every time autocomplete is triggered. For a large module like this, that means repeated disk reads and parsing, which adds significant lag.
• preLoaded modules, on the other hand, are loaded once when your editor starts up and kept in memory. After that, autocomplete pulls directly from the in-memory module data, eliminating the repeated overhead of reloading the large file.

Quick setup notes #

1. Double-check the path you’re using matches exactly what you had in extraPath:

   /Applications/Autodesk/maya2018/devkit/other/pymel/extras/completion/py
   

2. Depending on your editor (e.g., VS Code with Python extension, Sublime Text with LSP), make sure the preLoaded option accepts either full paths or module names. If it requires a module name:
   • Add the path to your Python sys.path first (you can do this via your editor’s Python settings)
   • Then specify the module name corresponding to that directory (look for the __init__.py file inside to confirm the module name)

Extra tip #

If you still notice minor delays after preloading, you can check if the module has submodules you don’t need for autocomplete—you might be able to preload only the specific submodules relevant to your workflow, trimming down the memory footprint even further.
