The critical feature of auto complete is discovery, not saving a couple of seconds of typing (its always too slow for that anyways). Even if a plugin exists (which I dont think one does) which has auto complete with in line documentation and method/property details (pretty crucial to discovery), theres not a chance in hell it succeeds in making it presentable in the terminal.

I think VSCode/atom fit in the nice space where you don't want huge, intensive projects, but you do want to do some real programming (aka you'll need this discovery and a good debugger).

>real programming

Ok :)

Language servers could solve this problem and let editors hook into a deeper source of understanding of what they're editing, without building in the functionality themselves.
