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 4622, JEP-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, " to the "Trusted Protocols" section
 * 4) Note: on older versions it's "xmpp= "

= 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] @=" %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 =

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:

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

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