RuboCop: Line is too long ← How to Ignore?

Question

I just added RuboCop to a rails project and installed the Sublime package to see RuboCop suggestions in the editor. I\'m trying to figure out how to change the maximum line leng

Answer 1

Creating a .rubocop.yml file (keep an eye on the initial . in the filename) in the root of your project, you'll have a bunch of options (check comments for what's your Rubocop version used as the way to handle LineLength has changed):

Metrics/LineLength: # for Rubocop < 0.78.0
Layout/LineLength: # for Rubocop >= 0.78.0
  # This will disable the rule completely, regardless what other options you put
  Enabled: false
  # Change the default 80 chars limit value
  Max: 120
  # If you want the rule only apply to a specific folder/file
  Include:
    - 'app/**/*'
  # If you want the rule not to apply to a specific folder/file
  Exclude:
    - 'db/schema.rb'
