Chime’s Go support uses gopls, which relies on a functioning go install, including a go executable in your PATH. Chime will respect any Go-specific environment variables you’ve configured as well.
You can use go env to better understand how Chime interacts with your go install.
Chime’s Ruby support is built around solargraph and rubocop. Configuring and setting up solargraph is a little involved, and very dependent on your Ruby/project environment. For the best experience, you will need to do some manual configuration.
Solargraph behavior can be customized with a yaml configuration file. This file can be either a .solargraph.yml file at the root of your project, or globally with ~/.config/solargraph/config.yml. With neither of these files are present, Chime will use a default setup. That default will disable rubocop diagnostics unless your project contains a .rubocop.yml configuration file.
