class RuboCop::Cop::Style::RedundantRegexpConstructor
Checks for the instantiation of regexp using redundant ‘Regexp.new` or `Regexp.compile`. Autocorrect replaces to regexp literal which is the simplest and fastest.
@example
# bad Regexp.new(/regexp/) Regexp.compile(/regexp/) # good /regexp/ Regexp.new('regexp') Regexp.compile('regexp')
