Duplicate capture group name

[jesus2099]

Unfortunately, Kiwi browser is still stuck on Chromium version 124, which does not handle proper alternative same name capture groups:

Uncaught SyntaxError: 
Invalid regular expression: 
/^(?:.+?[„“«‘] ?(?<release>.+) ?[“”»’] \S+ (?<artists>.+?)|(?<artists>.+?)のリリース(?:グループ)?「(?<release>.+)」) - MusicBrainz$/: 
Duplicate capture group name

OK, as it works in current Firefox for Android 129, I will just use Firefox for MASS MERGE, as long as Kiwi stays in version 124.

I reopen as I have just got 2 new NG reports (but 1 new OK report, as well):

• Windows 10 Vivaldi 6.8 (Chrome 126) Violentmonkey: OK
• Android 9 Kiwi (Chromium) 124 Violentmonkey: No sidebar button
• Android 9 Firefox 129 Violentmonkey: OK
• Firefox 129 Tampermonkey (Antiguastrea): Fetching recordings…
• Firefox 128 Greasemonkey (biocv): No sidebar button

So, all that just to have a cleaner code:

var sregex_title = "(?:.+?[„“«‘] ?(?<release>.+) ?[“”»’] \\S+ (?<artists>.+?)|(?<artists>.+?)のリリース(?:グループ)?「(?<release>.+)」) - MusicBrainz";
var match = document.title.match(new RegExp("^" + sregex_title + "$"));
var release_artists = match.groups.artists;
var release_title = match.groups.release;

But here is the support status of this thing:

• Firefox 129+
  • August 2024
  • caniuse.com does not know, but I successfully tested Firefox for Android OK too
  • Debian Firefox ESR is still on 115
• Chromium/Chrome 125+ (for Vivaldi, Kiwi Browser and Edge)
  • May 2024
  • Kiwi Browser is still on 124
• Safari 17+
  • September 2023
  • I don't know anything about it, maybe it's not available on old Macintosh OS

It's too cutting edge, too modern. Not widely supported. I think I will have to revert to old school but boring thing like:

var sregex_title = "(?:.+?[„“«‘] ?(.+) ?[“”»’] \\S+ (.+?)|(.+?)のリリース(?:グループ)?「(.+)」) - MusicBrainz";
var match = document.title.match(new RegExp("^" + sregex_title + "$"));
var release_artists = match[2] || match[3];
var release_title = match[1] || match[4];

OK I've worked around the limitation, so that we can still use older browser versions.
