This contains an Atom package for working with Atom IDE and the Apex Language Server.
Be sure to follow the instructions at https://ide.atom.io/. In particular, ensure that you have installed the atom-ide-ui package, e.g, using apm install atom-ide-ui.
For reference, here are the list of plug-ins I have in my Atom installation:

This is a personal project to validate the Apex Language Server with the Atom IDE and is not an officially supported product by Salesforce.
The grammar for the Apex programming language is taken from MavensMate-Atom.
