I need split the string, split character is "," but must skip content in "("...")".
const paramString = "gyro (param1, param2), proximity, Ultra Wideband (UWB) support, compass";
const paramArr = paramString.match(/[^(\)\,]+(\(.+?\))?/g).map( item => item.trim() );
In my result is paramArr[2] bad.
[ "gyro (param1, param2)", "proximity", "Ultra Wideband (UWB)", "support", "compass" ]
I need result:
[ "gyro (param1, param2)", "proximity", "Ultra Wideband (UWB) support", "compass" ]
Please advise how update my RegEx.
You should use negative lookahead. You are basically selecting all commas (with spaces after them to trim them) that are not followed by a ) if there is no ( before it:
const paramString = "gyro (param1, param2), proximity, Ultra Wideband (UWB) support, compass";
const paramArr = paramString.split(/,\s*(?![^(]*\))/);
console.log(paramArr);NOTE: it won't work for nested parentheses. It will fail in the following scenario:
const paramString = "gyro (param1, (param2)), proximity, Ultra Wideband (UWB) support, compass";
Try below mentioned regx , this will break your string in expected tokens only.
/[\w\ ]+(\([^)]*\))?(\ \w+)?/gi
The regx breaks your string in following tokens .
gyro (param1, param2)
proximity
Ultra Wideband (UWB) support
compass
Please follow the link for live demo of the regx :

(updated, regx to work only with non nested )
