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. ejabberd is recommended, but any server should work.

Building cadence requires the following tools:

• GNU Make.
• Python 3.5+. If your system's python command points to an outdated version, be sure to use make PYTHON=python3 to explicitly call the new interpreter.
• The Node Package Manager, npm. All other NPM dependencies are installed automatically.

Building

Configuration

First, create your configuration file from the template in install.dist.yml.

configure.py

The configure.py script will create this file automatically, but editing it manually allows additional configuration.

  -h, --help            show this help message and exit
  -s, --secure          Generate HTTPS or Secure WebSocket URLs
  --domain DOMAIN       XMPP domain to log in on.
  --muc MUC             The MUC conference server to connect to. [conference.DOMAIN]
  --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.
  --profile PROFILE     The installation profile to create or update [install.yml].

• 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.

If the installation profile already exists, it will be updated.

Manual configuration

After running configure.py (or copying install.dist.yml to install.yml) you can customize the configuration further.

The config key is merged into the default configuration that is defined in config/default.yml. All values there may be overridden here.

The install key contains several directives for the setup scripts:

• target and cdn.target designate directories where the files will be installed. These are optional; the build directory is already a functional installation.

• styles and packs define the stylesheets and emoticon packs. This list is automatically generated from the contents of assets/css/alt and emoticon-packs.

Make

After configuring, simply execute the Makefile.

$ make && make install

To build from a custom profile:

$ make profile=<profile.yml> && make install

The profile otherwise defaults to the most recent one used, or install.yml.
