ROMA - Route OSC Messages Asynchronously

All the roads lead to Rome.

WORK IN PROGRESS!!!

Introduction.

Roma is basically an osc router. It takes an osc path as source and distributes it over different targets. ...

Installation

$ npm install roma

Usage

var Roma = require('./lib/roma');
var roma = new Roma(devices,routes);

Device data format:

[{device1},{device2},{...}]

device1: {
    id:'live-device1',
    mirrors:['mirrorDeviceId1'], //optional. Must be an array of strings even if is only one mirror. When used redirects all incoming messages 
    fromPort: 9001, //optional
    toPort: 9000, //optional
    host: 'localhost'
}

Route data format:

Simple routing:

    {
     source:"/path/to/route",
     targets:[{ 
      deviceId: 'live-device1', // this device  must be in the device list.
          path: '/live/play/clip' //new path
          ,routeArgs:true 
          ,typetag: 'ii'  // type of the new params.must be in the same order as params
          ,params: [2,8] 
          }
          ]

    }

Param Reorder:

    {
     source:"/path/to/route",
     targets:[{ 
      deviceId: 'live-device1', // this device  must be in the device list.
          path: '/live/play/clip' //new path
          ,routeArgs:true 
          ,typetag: 'ii'  // type of the new params.must be in the same order as params
          ,params: [2,"#arg0"]  // new params, #argX string correspond to the original X param
          }
          ]

    }

Param process:

{
    source:"/source/path",
    targets:[{ 
      deviceId: 'dummy-device1'  // this device  must be in the device list.
          ,path: '/new/path' //new path
          ,typetag: 'ii' // type of the new params.must be in the same order as params
          ,params: [1,{  //param processor needs an object.
            input:0 // index of source param
            ,func:'add' //function to apply. "add","multiply" or "convert". 
            ,funcParams:{value:-1} //"add" and "multiply" 
            ,funcParams:{sourceMax:10,targetMax:300} //"convert"
            ,typetag:'i'
          }]
          ,routeArgs:true
        }]

}

Trigger by param

{
source:"/path/to/route",

targets:[{ 
       deviceId: 'target-id'
      ,trigger: true //Enables trigger
      ,triggerIndex: 0 //Index of the param
      ,triggerValue: 1 //Trigger value
      ,path: '/new/path'
      ,typetag: ''
      ,params: []
    }]

}
