How to tell Rubocop to ignore a specific directory or file

问题

My project is extending open-source classes from a third-party gem that we don't want to hold to the same coding standards as our own code. Refactoring the gem code isn't a viable option. We just want Rubocop to ignore the copied code.

How can I instruct Rubocop to completely ignore a file or directory?

回答1:

As per orde's comment with the link to the manual I found .rubocop.yml and added the following:

AllCops:
  Exclude:
    - 'path/to/excluded/file.rb'

where the path is relative to .rubocop.yml

回答2:

From rubocop/default.yml:

AllCops:
  Exclude:
    - 'node_modules/**/*'
    - 'vendor/**/*'

For your convenience, here is the .rubocop.yml I frequently used.

See formal explanation of .rubocop.yml here.

AllCops:
  Exclude:
    - Berksfile
    - recipes/basic.rb
    - attributes/*.rb

# Customize rules
Metrics/LineLength:
  Max: 95

MethodLength:
  Max: 35

Metrics/AbcSize:
   Enabled: false

BlockLength:
  Max: 70

I constantly bump by rubocop errors and warning. Thus I've published this post.
