I have text input like this

input:

function1( param1,param2, function2 (param1,function3(param1)),fun())

I want to parse out data like this:

fun()

function3(param1)

function2(param1,function3(param1))

function1( param1,param2, function2 (param1,function3(param1)),fun())

basically i need to find each individual function with parameters.

i tried using Regex \w+\s?$.*$ but it is giving me only this

function1( param1,param2, function2 (param1,function3(param1)),fun()).

Regex is not the best when dealing with multiple levels of nesting like this. You might want to simply look at writing a parser or finding an existing one that handles this for you. https://stackoverflow.com/questions/133601/can-regular-expressions-be-used-to-match-nested-patterns – juharr Aug 01 '19 at 14:42
Recursively unwrap functions and parse them. `const unWrap = s => s.replace(/\w+?$\s*/, '').replace(/$\s*$/, '')` – Xaqron Aug 01 '19 at 15:23
Thanks, I think unwrapping is the only way to extract all the functions from the string. – Techie Aug 02 '19 at 08:49
