get multiple occurance of a value after a specific word with regex

having a string similar to the following I would like to get the value (test1, test2) after the string -option (or wathever):

command --option test1 other stuff  --option test2  other stuff

I tried with as following

const regex = /--option ([^\w\s]) /g
regex.exec(string)

the problem is that I get just the first occurance and if there is more than 1 space it doesn't get the value

You can use

/--option\s*(.*?)(?=\s*--option|$)/gi

See the regex demo. Details:

  • --option - a literal string
  • \s* - 0 or more whitespaces
  • (.*?) - Group 1: any zero or more chars other than line break chars, as few as possible
  • (?=\s*--option|$) - immediately followed with 0+ whitespaces and --option or end of string.

See JavaScript demo:

const str = 'command --option test1 other stuff  --option test2  other stuff';
const reg = /--option\s*(.*?)(?=\s*--option|$)/gi;
const results = [...str.matchAll(reg)];
console.log( Array.from(results, x => x[1]) );
