Configuration via sider.yml

Here are some example settings for Rails Best Practices in sider.yml, under rails_best_practices:

linter:
  rails_best_practices:
    gems:
      - "slim"
    vendor: false
    spec: true
    test: true
    features: true
    exclude: examples
    config: .rails_best_practices.yml

Options

Name	Type	Description
root_dir	string	Directory in which the analyzer runs.
gems	array<string, object>	Definition of gems to be installed.
vendor	boolean	Add --vendor flag. Default: true
spec	boolean	Add --spec flag. Default: false
test	boolean	Add --test flag. Default: false
features	boolean	Add --features flag. Default: false
exclude	string	Patterns passed as --exclude option.
only	string	Patterns passed as --only option.

Analyzing view templates

Rails Best Practices supports some template engines. Sider finds the following gems in Gemfile.lock and installs them automatically for backward compatibility:

• slim
• haml
• sass
• sassc

These gems will not be installed when the gems option is specified. We encourage you to explicitly specify gems in the gems option in sider.yml as follows:

linter:
  rails_best_practices:
    gems:
      - "slim"
      - "sassc"
