Work is being done in mozjs-24 branch.

One major issue is that most major distros don't ship this version in their repos afaik.

• Get it building
• Fix crashes
• Build mozjs-24 on Windows w/ VS2013

As a derivative (also affects plugins) of hexchat, this project has to be GPLv2-compatible. (the MPL isn't)
SpiderMonkey, as part of Firefox, is afaik under multiple licenses MPL/GPL/LGPL, therefore a license change shouldn't be problematic.
GPLv2+ would be nice
good project ;)

I have the following code to display incoming Twitch whispers:

function whisperIn_cb(words) {
    // words example: [':[email protected]', 'WHISPER', 'danpcg', ':test', 'message']
    // should print "pcgdan > danpcg: test message"
    var nick = words[0].replace(/^:(.+)!.+$/, '$1');
    var msg = words.slice(3);
    msg[0] = msg[0].slice(1); // remove leading ":" (':test')

    print(nick + ' > ' + words[2] + ': ' + msg.join(' '));

    return EAT_ALL;
}

hook_server('WHISPER', whisperIn_cb);

It works fine unless the whispered message has more than 27 words. If the message has 28 words or more, the length of the array words is over 30, which probably causes the crash. The code in whisperIn_cb() is not important, as HexChat still crashes if the function is empty.

I have noticed, that if you pass an array that has over 30 elements to a hook_command callback function (e.g. a long outgoing whisper message), the array gets truncated to the length of 30. Is it possible to have arrays that are longer than 30 words? If not, can they at least be truncated for hook_server callback functions, to prevent the crash?

P.S. I have written the same function using the Python interface and it works without any issues (tested with a 100-word whisper).

Perhaps you could add support for making HTTP requests in JS with libcurl?

I would like to execute a command in a certain context from another context. For example if I type !test in context A, I want something to happen in context B. From what I have read, this is possible in the Python Interface, but I can't get it to work with JavaScript. The context is always undefined. Am I doing something wrong or does the JavaScript Interface not support context objects (the feature list states "Full coverage of hexchat api", so I'm not sure if context is a part of the API)?

This is a snippet of the code I tried.

function twitchWhisper(nick, msg) {
  var channels = get_list('channels');
  var server, channel, cnc;
  for(var c in channels) {
    if(channels[c].network == 'Twitch group chat' && channels[c].type == 2) {
      cnc = channels[c].context; // is undefined
      server = channels[c].server;
      channel = channels[c].channel;
      break;
    }
  }
  cnc = find_context(server, channel); // returns undefined
  cnc.command('PRIVMSG #jtv :/w ' + nick + ' ' + msg); // results in an error
}
