passing string as a condition of a method in ruby

Question

Is there a way to create a condition through string manipulation. here is the code where I attempted to pass a string as a condition into include? method.

"hello eveyone in the house".include?(%w('hello' 'world' 'new\ york'    'place').join(" || ").to_s)

Answer 1

An conditional as argument to include? is not possible, because include? accepts only a string argument.

But you can write something like this:

['hello', 'world', 'new york', 'place'].any? { |word|
  "hello everyone in the house".include?(word)
}

Or you could generate a regexp from your strings:

"hello eveyone in the house".match?(
  /#{['hello', 'world', 'new york', 'place'].join('|')}/
)
