Refactoring 2 Regexps

Question

I want to split the string

smartcode = '{{question.answer}}'

to obtain just eventually

'answer'

I know this works

smartcode.split(/\{{(.*?)\}}/).last.split(/\.(?=[\w])/).last

but it's not the better way i guess...

Answer 1

I suggest:

smartcode = '{{question.answer}}'
smartcode.match(/\.(\w+)/)[1]
#=> "answer"

Or when you want to ensure that the specific structure with the surrounding brackets and two words separated by a dot:

smartcode.match(/{{\w+\.(\w+)}}/)[1]
#=> "answer"
