cadence

cadence is a JavaScript-based web client for XMPP Multi-User Chat powered by strophe.js.

Requirements

• An XMPP server with Multi-User Chat and either BOSH or WebSocket support is required to run cadence.
• Python 2.7+ (or 3+) and GNU Make are required in the build process.
• Optional JS and CSS compression uses the YUI Compressor utility. Install it using your distribution's package manager or download it here: https://github.com/yui/yuicompressor/releases

Building

Configuration

First, run the configure script. The script can be executed from any location outside the source directory ("out-of-source") or directly inside ("in source").

These arguments are supported:

  -h, --help            show this help message and exit
  -s, --secure          Generate HTTPS or Secure WebSocket URLs
  --domain DOMAIN       XMPP domain to log in on.
  --url URL             BOSH or WebSocket URL to connect to [PROTOCOL://HOST:PORT/PATH]
  --protocol            The protocol to connect through [http, https, ws, wss].
  --host                The host to connect to, if it differs from the XMPP domain [DOMAIN]
  --port                The port to connect to [5280, 5281].
  --path                The socket path on the server to connect to [/http-bind or /websocket].
  --session-auth AUTH   The URL to use for session authentication.
  --muc MUC             The MUC conference server to connect to. [conference.DOMAIN]
  --chatbot CHATBOT     The displayed name of the virtual ChatBot. ["Info"]
  --title TITLE         The page title. ["cadence"]
  --style STYLE         The default style. ["Stygium"]
  --cdn-url CDN_URL     Base URL for resources. (Optional)
  --prefix PREFIX       Directory to install cadence to ["."]
  --cdn-prefix CDN_PREFIX
                        Directory to install resources to [PREFIX]
  --mode debug|aggregate|minify
                        Whether to optimize JS/CSS files ["minify"]

• Only --domain is strictly required. --muc and --url are required if they differ from the default values.

• --session-auth is required if you would like to hook into an existing site's login system via ejabberd-auth-php. It is the public URL of the rpc.php script in that software's session authentication plugin.

• --chatbot and --title merely affect the client branding.

• The --prefix is required to cleanly deploy the application to a directory. (An in-source build is a functional installation, but an out-of-source build must be installed before use, because static resources are not copied to the build location.)

• The --cdn-prefix and cdn-url options are used to deploy the application's resources to a CDN. If this is given, all but the index.html file are deployed there. (You can also use the CDN for index.html file with --prefix, but this will make the application harder to find, and will break session-authentication due to cross-site security policies.

The --mode determines whether to aggregate and minify the scripts and stylesheets. For development, "debug" is recommended.

Make

Then simply execute the Makefile.

$ make && make install

Customizing the Settings

It is not recommended to edit js/core/config.js (if this file even exists, and has not been aggregated and minified), because it will be overwritten if the software is rebuilt from source.

Instead, the installer places a file named config.custom.js into the install directory along with your index.html file. Add any configuration changes to this file by assigning or deleting keys in the global config object.
