This package provides a language client for C and C++, via the CCLS or CQuery language servers.
This package can be used out-of-the-box with Atom IDE, and perhaps with any plugin that supports atom-languageclient.
You will also need to generate a suitable set of compile commands.
If you have completed both of these steps, simply select your preferred provider in the package settings, and voila, it should work.
If the package fails to work (check the debug console), please verify that either the
cquery binaries are present in your PATH and run correctly. If you still can't get it to work, open an issue in the project's repository.
