rubocop-disable_syntax

rubocop-disable_syntax is a RuboCop plugin that allows to disable some unfavorite ruby syntax such as unless, safe navigation etc.

• ruby 3.2+
• rubocop 1.72+

Add this line to your application's Gemfile:

gem 'rubocop-disable_syntax', group: :development, require: false

And then run:

$ bundle install

You need to tell RuboCop to load the rubocop-disable_syntax extension.

Put this into your .rubocop.yml.

plugins:
  - rubocop-disable_syntax

Note: The plugin system is supported in RuboCop 1.72+. In earlier versions, use require instead of plugins.

All the ruby syntax features are enabled by default and so this gem acts as a no-op. You need to manually configure which ruby features you want to disable:

Style/DisableSyntax:
  DisableSyntax:
    - unless
    - ternary
    - safe_navigation
    - endless_methods
    - arguments_forwarding
    - numbered_parameters
    - pattern_matching
    - shorthand_hash_syntax
    - and_or_not
    - until
    - percent_literals

• unless - no unless keyword
• ternary - no ternary operator (condition ? foo : bar)
• safe_navigation - no safe navigation operator (&.)
• endless_methods - no endless methods (def foo = 1)
• arguments_forwarding - no arguments forwarding (foo(...), foo(*), foo(**), foo(&))
• numbered_parameters - no numbered parameters (foo.each { puts _1 })
• pattern_matching - no pattern matching
• shorthand_hash_syntax - no shorthand hash syntax ({ x:, y: })
• and_or_not - no and/or/not keywords (should use &&/||/! instead)
• until - no until keyword
• percent_literals - no any % style literals (%w[foo bar], %i[foo bar], %q("str"), %r{/regex/})
