XMPP URIs

An XMPP URI is a Uniform Resource Identifier that makes a Jabber ID "clickable" in web browsers and such. Unfortunately, support for XMPP URIs is not (yet!) common in popular software applications, so you need to set it up manually. This page describes how...

Formal Definition

For those interested in a formal definition of XMPP URIs, read RFC 5122, XEP-0147 and the querytypes registry.

Web browsers

Firefox

To XMPP URIs clickable in the Firefox web browser, do this:

1. Type "about:config" in the url bar
2. Right-click and select New->String
3. Enter "network.protocol-handler.app.xmpp" as the preference name
4. Enter the application to run

Opera

To make XMPP URIs clickable in the Opera web browser, do this:

1. Open your opera6.ini file
2. find (or except add) "Trusted Protocols" section
3. add "xmpp=0,0,<application to run>" to the "Trusted Protocols" section
4. Note: on older versions it's "xmpp=<application to run>"

Konqueror

In KDE4 create a file in $HOME/.kde4/share/kde4/services/xmpp.protocol

[Protocol]
exec=psi --uri "%u"
protocol=xmpp
input=none
output=none
helper=true
listing=false
reading=false
writing=false
makedir=false
deleting=false
Icon=""

In KDE3 is similar, but the file will be $HOME/.kde/share/services/xmpp.protocol and you might have to replace the exec line with exec=psi --uri `echo "%u" |sed s/%40/@/ `

Operating systems

Linux

To follow.

Mac OS X

Install the XMPP-IRI helper application linked to from here.

Adium registered itself as a handler for XMPP URIs, "Just Works" with Camino.

Windows

Paste the following in Notepad and save to a file with an ".reg" extension. Then double-click on it and answer yes to the prompt to import the settings into your registry. Be sure to enter the path to your XMPP-URI capable Jabber client. See the Registering an Application to a URL Protocol article in MSDN for more details.

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\xmpp]
@="URL:XMPP Protocol"
"EditFlags"=dword:00000002
"URL Protocol"=""
[HKEY_CLASSES_ROOT\xmpp\shell]
[HKEY_CLASSES_ROOT\xmpp\shell\open]
[HKEY_CLASSES_ROOT\xmpp\shell\open\command]
@="<application to execute> %l"

Jabber Clients

List clients supporting XMPP URIs here.

jabber.el

jabber.el supports XMPP URIs from version 0.7.1. How to set it up is described in the documentation.

Gajim

Using Firefox, set the string for network.protocol-handler.app.xmpp to 'gajim-remote handle_uri' in about:config. For Opera add 'xmpp=0,0,gajim-remote handle_uri' under [Trusted Protocols] (I had to add Trusted Protocols at the bottom) in opera6.ini.

Coccinella

Coccinella supports many of them but not all, see coccinella/components/ParseURI.tcl And the Mac desktop bindings may be flaky.

Miranda IM

Miranda IM supports handling of XMMP URIs since version 0.7.1.2 of jabber plugin. Implementation requires File Association Manager plugin which can be found at http://addons.miranda-im/.

MediaWiki

Last version

Part 1

In mediawiki-1.15.1\includes\DefaultSettings.php

There is:

/**
 * The external URL protocols
 */
$wgUrlProtocols = array(
	'http://',
	'https://',
	'ftp://',
	'irc://',
	'gopher://',
	'telnet://', // Well if we're going to support the above.. -ævar
	'nntp://', // @bug 3808 RFC 1738
	'worldwind://',
	'mailto:',
	'news:',
	'svn://',
);

You must add:

'xmpp:',

Result:

/**
 * The external URL protocols
 */
$wgUrlProtocols = array(
	'http://',
	'https://',
	'ftp://',
	'irc://',
	'gopher://',
	'telnet://', // Well if we're going to support the above.. -ævar
	'nntp://', // @bug 3808 RFC 1738
	'worldwind://',
	'mailto:',
	'xmpp:',
	'news:',
	'svn://',
);

Part 2

In mediawiki-1.15.1\maintenance\fuzz-tester.php

There is:

            // implicit link creation on URIs.
            "http://",
            "https://",
            "ftp://",
            "irc://",
            "news:",
            'gopher://',
            'telnet://',
            'nntp://',
            'worldwind://',
            'mailto:',

            // images.

You must add:

'xmpp:',

Result:

            // implicit link creation on URIs.
            "http://",
            "https://",
            "ftp://",
            "irc://",
            "news:",
            'gopher://',
            'telnet://',
            'nntp://',
            'worldwind://',
            'mailto:',
            'xmpp:',

            // images.

Part 3

In all skins (\mediawiki-1.15.1\skins\***\main.css)

There is:

#bodyContent a[href ^="mailto:"],
.link-mailto {
    background: url("mail_icon.gif") center right no-repeat;
    padding-right: 18px;
}

You must add:

#bodyContent a[href ^="xmpp:"],
.link-xmpp {
    background: url(xmpp_icon.png) center right no-repeat;
    padding-right: 10px;
}

Result:

#bodyContent a[href ^="mailto:"],
.link-mailto {
    background: url("mail_icon.gif") center right no-repeat;
    padding-right: 18px;
}
#bodyContent a[href ^="xmpp:"],
.link-xmpp {
    background: url(xmpp_icon.png) center right no-repeat;
    padding-right: 10px;
}

And in the same folder as the CSS file, download and place this icon file.

older

If you run a MediaWiki you may also want it to support xmpp: URIs, which it doesn't by default. Thankfully the fix is easy. In your LocalSettings.php file, add the line:

$wgUrlProtocols[] = "xmpp:";

That's all you technically need to do. It can also make things prettier though if you add the Jabber icon next to all such links. To do this, locate the .css file for the skin you are using (e.g. skins/monobook/main.css) and append the following code:

#bodyContent a[href ^="xmpp:"],
.link-xmpp {
        background: url(xmpp_icon.png) center right no-repeat;
        padding-right: 10px;
}

And in the same folder as the CSS file, download and place this icon file.
