Change email subject

[Jacob Moen]

I know that one can mess around with the email templates, but I see no way to change the subject of the email.
Like:

[sitename #topic_id] topic_name

I need to include the topic id in the subject because I need to parse the subject ( postfix forward pointing to a Yii console controller, if you must know) - do I need to mess around in the source code?

Edit:
I am implementing reply by email, btw.
And since I am a PHP developer, I am using the api and dirty tricks

I also do know that I can grab the topic id from the URL - that thought came to me just now - but it is easier to just regex the subject.

Emailer fires:

Plugins.fireHook('filter:email.modify', data, next);

Listen to that hook, modify subject in data, voila.

Ok, I will perhaps try and look into that

I just did a stupidly simple (stupid?) plugin but it does not seem to do much

(function(module) {
    "use strict";

    var autoreplyit = {};

    autoreplyit.filter = function(data) {
        data.subject = data.subject + ' #' + data.pid;
    };

    module.exports = autoreplyit;
}(module));

{
    "id": "nodebb-plugin-autoreplyit",
    "name": "NodeBB Autoreply email subject changer",
    "description": "NodeBB Plugin that changes the email subject field to include the topic id.",
    "url": "https://github.com/jacmoe/nodebb-plugin-autoreplyit",
    "library": "./library.js",
    "hooks": [
        { "hook": "filter:email.modify", "method": "filter" }
    ]
}

Check to see that autoreplyit.filter is executed (maybe a console.log?)

Your filter will need a callback:

autoreplyit.filter = function(data, callback) {
  data.subject = data.subject + ' #' + data.pid;
  callback(null, data);
};

It works

(function(module) {
    "use strict";

    var autoreplyit = {};

    autoreplyit.filter = function(data, callback) {
        var re = /http:\/\/nodebbjacmoe-jacmoe\.rhcloud\.com\/topic\/(\d+)/;
        var str = data.plaintext;
        var found = str.match(re);
        data.subject = data.subject + ' #' + found[1];
        callback(null, data);
    };

    module.exports = autoreplyit;
}(module));

Totally hard-coded, of course

Edit:
I am fully aware that it is only a matter of time before a kind soul points out to me that I can easily get the site url from a dark corner of the API - but, hey: it works.
Now the receiving PHP script can grab the topic id and make sure that it is sent to the right place.

Thanks a lot @julian

@Jacob-Moen Hey, if it works, it works!

Now you've written a NodeBB plugin

[Jacob Moen]

I threw in an if(found) just in case - but I am always amazed by how little code is required.
That seem to happen a lot with Node.js and a well written software entitled NodeBB
