Using lumo as a foundation for Language Server Protocol

[abhi18av]

Hi @anmonteiro ,

I'd like to suggest that since with lumo we already have an awesome independent story for ClojureScript with the ability to use any NodeJS package, perhaps lumo can be used as a base for a Language Server Protocol .

This will enable the futher development of the Clojure(Script) repls in modern Electron based text editors, VsCode and Atom.

I read your blog post about future of Lumo and I thought that this is a great goal for Lumo, to enable further adoption of ClojureScript and reaching out to less imposing code editors.

Provided that it's easy to interface with code in npm packages, the vscode-languageserver package would make this easy to do (more info on GitHub). I've started looking into how to use it from ClojureScript/Lumo but it's been a while since I've used Clojure so I'm having to refresh my memory a bit :)

I think it should be possible to launch the Lumo REPL inside of VS Code's Integrated Terminal and host a language server inside of it for fully interactive development. I do something similar in the PowerShell extension.

@daviwil Well Lumo is nothing but a custom ClojureScript init script on top of Node, so NPM dependencies are supported by default. In this comment I explain how to include NPM dependencies in Lumo. Spoiler: npm install left-pad and (js/require "left-pad") in Lumo.

@anmonteiro: Would it make sense to include the examples on how to include/require npm packages in the README, or in the docs somewhere else?
