Class: RuboCop::Cop::Lint::PercentSymbolArray
- Includes:
- PercentLiteral
- Defined in:
- lib/rubocop/cop/lint/percent_symbol_array.rb
Overview
This cop checks for colons and commas in %i, e.g. ‘%i(:foo, :bar)`
It is more likely that the additional characters are unintended (for example, mistranslating an array of literals to percent string notation) rather than meant to be part of the resulting symbols.
