def gen_name path
  extracted_name = path.split(%r{[\s_/]})&.uniq&.delete_if do |s|
    s.empty? || s == 'cs' || s == 'assess' || s == 'track'
  end
  extracted_name = (extracted_name&.length || 0) > 1 ? extracted_name&.join('_') : extracted_name&.pop
  ["@_instrument_#{ extracted_name }_track", extracted_name]
end

.instrument(path) ⇒ Object

Unites the different require methods into one, using only the provided path for the C patches parameters
