Hi,

I'm trying to extract one or multiple usernames from a given search term:

cartoons -user:donald,mickey,goofy

However, with the regex I came up with I only get two submatches:

/\-user\:(\w+)(?:\,(\w+))*/i
submatches: 1: donald 2: goofy

I've been twiddling with this for two hours now, but still don't know what I'm doing wrong. How do I have to change the expression to get all usernames as submatches?
Thanks in advance.

As far as I know, there's no way to do it like that. You could use this, even if it's a bit of a workaround. You may have to tweak it however, depending on how the file is organised.

var arr = str.replace(/.*\-user\:(\w+)((\,\w+)*).*/i,"$1$2").split(",");

Yeah. After further googling I stumbled upon the term "atomic groups", which seems to be what I'm used to from other languages but isn't supported in js :~( So I solved my problem with String.split as you suggested. Thanks for your help!
