The Code Climate Credo engine can show you refactoring opportunities in your code, complex and duplicated code fragments, warn you about common mistakes, show inconsistencies in your naming scheme and help you enforce a desired coding style.

Enable the Plugin

engines:
  credo:
    enabled: true
    strict: true
    all: true
    only: "warning"
    ignore: "readability"
    included: 
     - "some_path/"
     - "some_other_path/"
    excluded:
     - "some_path/"
     - "some_other_path/"

• strict - if you want to enforce a style guide and need a more traditional linting experience
• all - if you want to use all checkers
• only - run only a subset of checks
• ignore - ignore selected checks
• included - include any paths you wish to analyze
• excluded - exclude any paths you don't want to analyze
