Class: Rubocop::Cop::Style::FavorSprintf
- Defined in:
- lib/rubocop/cop/style/favor_sprintf.rb
Overview
This cop checks for uses of String#%.
It cannot be implemented in a reliable manner for all cases, so only two scenarios are considered - if the first argument is a string literal and if the second argument is an array literal.
