Nine years ago (!!) I offered you my Automatic chrome extension generator and today I stumbled on errors in the extensions tab of chrome:

Manifest version 2 is deprecated, and support will be removed in 2023.
+ See https://developer.chrome.com/blog/mv2-transition/ for more detai
+ls.
[download]

So I tried to simply put "manifest_version": 3, but then it complained about script no more supported and to switch to service_worker so I changed this.. and then onclick to chrome.contextMenus.onClicked.addListener .. and then..

Can some kind soul look the below JS code and help me to fix it?

The goal is simple: create a custom context menu entry acting on selected text to craft a GET to open in a new tab.

#!/usr/bin/perl
use strict;
use warnings;

# supporting manifest v 3
# https://developer.chrome.com/blog/mv2-transition/
# https://developer.chrome.com/docs/extensions/mv3/migrating_to_servic
+e_workers/

# January 2023: The Chrome browser will no longer run Manifest V2 exte
+nsions. 
# Developers may no longer push updates to existing Manifest V2 extens
+ions.

my $version = 2;

my $folder = $ARGV[0];
my $url  = $ARGV[1];

die "$0 Directory_Name URL" unless $ARGV[1];

(my $descr = $folder) =~ s/_+/ /g;
my $longname = 'Perl genarated extension - '.$descr;

mkdir $folder or die "Cannot create $folder: $!";
chdir $folder or die "Cannot enter $folder: $!";
# the manifest
open MANIF, '>', 'manifest.json' or die "Cannot open a file to write i
+n: $!";
my $manifest = '{
   "manifest_version": 3,
   "description": "'.$descr.'",
   "background": {
    "service_worker": "background.js"},
   "name": "'.$longname.'",
   "permissions": [ "contextMenus", "tabs" ],
   "version": "1.0"
}';
print MANIF $manifest;
close MANIF;
# the jscript
open JSCRIPT, '>', 'background.js' or die "Cannot open a file to write
+ in: $!";
my $background ='function customfunc(info)
{
 var searchstring = info.selectionText;
 chrome.tabs.create({url: "'.$url.'" + searchstring})
}

chrome.contextMenus.onClicked.addListener(function(info, tab) {
    if (info.menuItemId == "'.$descr.'") 
});';

print JSCRIPT $background;
close JSCRIPT;

In the case it is useful here the relevant part of diff -ing the two versions

16c26
<    "manifest_version": 2,
---
>    "manifest_version": 3,
19c29
<     "scripts": ["background.js"]},
---
>     "service_worker": "background.js"},

< chrome.contextMenus.create({title: "'.$descr.'", contexts:["selectio
+n"], onclick: customfunc});';
---
