nodebb-plugin-mention fix allowing Redactor to send notifications to mentioned groups

[JJSagan]

Hi Devs,

EDIT: THE BELOW ISSUE WAS RESOLVED -> SEE MY 3rd POST.

I found a weird problem:

Steps to reproduce:

1. Post a new topic and mention a group.
2. Create a callback and wait for action:notification.pushed
3. Print the uids.

The first callback will send a message to all followers.
There used to be a second callback sending the same to the groups. I don't see that anymore.

My code is synced to master as of today's AM.

Any idea?
JJ.

Looks like the issue stems from the Mention plugin.
Mentions.notify returns early since the regex was not successful identifying a match. See below failed code.
@julian and @baris this might be a bug.

Mentions.notify = function(data) {
	var postData = data.post;
	var cleanedContent = Mentions.clean(postData.content, true, true, true);
	var matches = cleanedContent.match(rawRegex);

	if (!matches) {
		return;
	}

Hi @julian and @baris,

Took some time to review the plugin code and twitter's @Mention code. Originally I thought the issue was due to non-unicode regex, but it turns out your search string was perfect.

I should have mentioned that I am using nodebb-plugin-composer-redactor (and yeah, I am dying to replace it with nodebb-plugin-composer-quill once the plugin is completed - its almost showtime: see: https://community.nodebb.org/topic/12856/nodebb-plugin-composer-quill-wysiwyg-alternative-to-redactor).

Well, it turns out that redactor inserts html tags into the post content, and while the mention plugin was 99.9999(+Ɛ)% redactor proof, it was missing a tiny piece of code that gets rid of the tags.

To that end, kindly consider the following very minor changes to the mention plugin:

1. In package.json add the lib:

"striptags": "^3.1.1"

2. In library.js add striptags:

Line 20:

var striptags = require('striptags');

Line: 80:

var cleanedContent = Mentions.clean(striptags(postData.content, [], '\n'), true, true, true);

That's it. Once done, Redactor will work with Mentions and RTL languages will be supported as a bonus.

You may want to close the below issue in github once said changes are committed: https://github.com/julianlam/nodebb-plugin-mentions/issues/60

I got to learn Regex today and went to sleep dreaming of solving the mysteries of the universe with unicode search strings.

Have fun
JJ.
