Ruby: Merging variables in to a string

Question

I\'m looking for a better way to merge variables into a string, in Ruby.

For example if the string is something like:

\"The animal action<

Answer 1

The standard ERB templating system may work for your scenario.

def merge_into_string(animal, second_animal, action)
  template = 'The <%=animal%> <%=action%> the <%=second_animal%>'
  ERB.new(template).result(binding)
end

merge_into_string('tiger', 'deer', 'eats')
=> "The tiger eats the deer"

merge_into_string('bird', 'worm', 'finds')
=> "The bird finds the worm"
