• Ameba::Rule::Lint::RequireParentheses
• Ameba::Rule::Base
• Reference
• Object

Overview

A rule that disallows method calls with at least one argument, where no parentheses are used around the argument list, and a logical operator (&& or ||) is used within the argument list.

For example, this is considered invalid:

if foo.includes? "bar" || foo.includes? "baz"
  # ...
end

And need to be written as:

if foo.includes?("bar") || foo.includes?("baz")
  # ...
end
