Chat Tags is a mark-up parser for Special:Chat. It allows users to add formatting to their in-chat messages. Such formatting includes the ability to add colors to their messages, change the font of their messages, alter the font size, alter the font weight, and the background of their messages. This gives users the creative freedom to better express themselves while in chat.

New tags for the script can be requested over on the talkpage.

Installation

Chat Tags can easily be installed by editing the following line into your wiki's MediaWiki:Chat.js page.

importScriptPage('MediaWiki:ChatTags/code.js', 'shining-armor');

Or if your wiki is already using an importArticles statement you can add the following line to your scripts section.

        'u:shining-armor:MediaWiki:ChatTags/code.js',

Additionally, if you would like to enable the image or youtube tag you will need to add the following line ABOVE the script import.

var chatags = { images: true, videos: true };

Usage

To use Chat Tags on your wiki after installation one must only wrap their text in the designated tags that you will find below. Chat Tags functions much like HTML in that it requires a beginning tag that shows where you wish to start formatting and and ending tag to show when to stop formatting. If you do not include both of these tags then your text will be ignored by the script.

Tags must end in the order that they start

For example:


[c="red"]This text will be red.[/c] -> This text will be red.

[c="#FF0000"]This text will also be red.[/c] -> This text will also be red.

[bg="red"]This text will have a red background.[/bg] -> This text will have a red background.

[b]This text will be bold.[/b] -> This text will be bold.

[c="red"][b]This text will be red and bold.[/b][/c] -> This text will be red and bold.

Developers

ChatTags is very much extensible and allows developers to easily add and remove tags as they see fit.

In order to add a tag you must first import ChatTags using the following line.

importScriptPage('MediaWiki:ChatTags/code.js', 'shining-armor');

After doing this you must add an entry to the tags object in order to do this you must pick a name that has not been previously chosen. All default tags are listed above. After selecting the name for your tag you must then decide whether it is stand-alone or a pair.

A stand alone tag only require and opening tag (see: img, yt).

A pair tag requires both an opening and closing tag (see: c, u, bg)

After deciding the structure of your tag you must decide if you want it to accept a parameter or not. After deciding this you want to create your object entry. For example purposes we will be creating a user tag that turns their text color purple.

To add an entry we must do the following below our import.

//... import ...
chatags.tags['user'] = function(s,t) {        // S is the user string, T is the tag
    if (t.charAt(0) === '/') {                // We have been given the ending tag
        s = s.replace('[/user]', '</span>');
    } else {                                  // We have been given the opening tag
        s = s.replace('[user]', '<span style="color:purple">');
    }
    return s;                                 // Return the user string for further parsing
};

Now, let's say that we want to let the user enter their own color, we'd need to do something like the following.

//... import ...
chatags.tags['user'] = function(s,t) {
    if (t.charAt(0) === '/') {
        s = s.replace('[/user]', '</span>');
    } else {
        try {
            t = t.split('="');
            t[1] = t[1].replace('"', '');
            s = s.replace('[user="' + t[1] + '"]', '<span style="color:' + mw.html.escape(t[1]) + ';">');
        } catch(e) { console.log(e) }
    }
    return s;
};

When dealing with user input you must always use mw.html.escape() to escape the input to prevent script injection.
