RuboCop: Line is too long ← How to Ignore?
In your code, you can disable a bunch of lines like this:
# rubocop:disable LineLength
puts "This line is lonnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnng"
# rubocop:enable LineLength
Or add this to your .rubocop.yml
file to increase the max length:
Metrics/LineLength:
Max: 100
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'
With latest changes at rubocop gem version 0.78.0 at 18-12-2019, from now on LineLength cop move from Metrics department to Layout department. So basically if any one need to disable long lines with using version number higher than 0.78.0 should do it like this.
# rubocop:disable Layout/LineLength
"I'm a really long line"
# rubocop:enable Layout/LineLength
Also .rubocop.yml
configuration is changed to this.
Layout/LineLength:
Max: 100
