Class: RuboCop::Cop::Style::SymbolArray
- Includes:
- ArraySyntax, ConfigurableEnforcedStyle
- Defined in:
- lib/rubocop/cop/style/symbol_array.rb
Overview
This cop can check for array literals made up of symbols that are not using the %i() syntax.
Alternatively, it checks for symbol arrays using the %i() syntax on projects which do not want to use that syntax, perhaps because they support a version of Ruby lower than 2.0.
