Well, when running EmmyLua with xmake.lua files it gives lots of errors, until you pause the language server. So, EmmyLua should be able to find globals that are defined for xmake and indices in tables like for package and such. This would also make development a lot easier because xmake's own plugin for vscode has very minimal auto-completion and insights.

This doesn't seem to require xmake to do anything.xmake has its own API, you can only use the xmake-vscode plugin. The native lua plugin has no effect on xmake.
