How to Install

The cql-language package has been published to the Atom package repository, so installation is simple:

  1. If you don't have Atom, download and install it.
  2. Install the cql-language package by follow the instructions for installing packages a. The cql-language package requires both a Java v1.8 runtime and a correct Java Path. If the installation fails to detect either, you will be prompted to download and install Java and/or set a correct Java Path.

Using the CQL support in Atom

After you've installed the cql-language package, open any .cql file in Atom. As long as the file has the .cql extension, syntax highlighting will be automatically applied.

NOTE: Syntax highlighting makes editing and reviewing CQL files easier, but does not validate the technical or syntactic validity of the CQL statements. This package does not flag invalid CQL.
