How to get all content between two curly brackets, ignoring those in quotation marks?

Question

I'm currently using the following regex with partial success:

/\{[^{}]+\}/g

But it fails for this situation:

{get('{')} {b}

I just want to ignore the { and } when they are between quotation marks, and get the right result:

get('{')

and

b

You may use this regex to capture inner strings for both cases:

\{((?:[^}']*')*[^}']*)\}

Assuming quotes are balanced and unescaped.

• \{ : Match a {

    • [^}']* : Match 0 or more characters that are not } and not '
    • ' : Match a single quote
  • )* : End non-capture group. Match 0 or more of this group
  • [^}']* :
• ) : End capture group #1
• \} : Match a }
