PercentLiteral
Defined in:
lib/rubocop/cop/style/percent_literal_delimiters.rb

Overview

This cop enforces the consistent usage of ‘%`-literal delimiters.

Specify the ‘default’ key to set all preferred delimiters at once. You can continue to specify individual preferred delimiters to override the default.

Examples:

# Style/PercentLiteralDelimiters:
#   PreferredDelimiters:
#     default: '[]'
#     '%i':    '()'

# good
%w[alpha beta] + %i(gamma delta)

# bad
%W(alpha #{beta})

# bad
%I(alpha beta)
