The Sinespace Editor pack includes the tools required to create a scripting auto complete file for use with editors such as Microsoft VS Code & Atom. Below is a demonstration of how to set up with VS Code.
From inside your Unity project select the Sinespace drop down menu and select tools/scripting/generate auto complete file for Atom.
Locate the root folder for your Unity project in my example documents/2017 then click save (you do not need to enter a file name here)
A new file will be added to your project folder called .luaautocompleterc, This file contains the Sinespace Scripting API information. We are now ready to setup our editor of choice.
