Ruby – Multiple string replacements with gsub

For making multiple substitutions  in a string in one call of gsub, you could do something like this

matchers = {'some_term1' => 'string_to_replace_with1', 'other_term2' => 'string_to_replace_with2'}
string = 'some_term1_other_term2'
string.gsub(/some_term1|other_term2/) { |match| matchers[match] }
