experiment with node-red

Attempt to add multi inputs

description:

Function contain a new parameter, nbr of inputs. If this value is bigger than 1 the flow send the msg only if all the inputs msg are filled . Then use the name of the input node to create a new msg like:

msg.load = { functionInput1: xxxx, functionInput2: xxxx, functionInput3: xxxx  }

To "reset" the inputs msg we have a special node called :" synNode..."

url: http://127.0.0.1:1880/

to use it with Nodeclipse (Enide): npm install -g nodeclipse nodeclipse -p

dev mode:

grunt dev you can use full debug (got to install node-debug) node-debug red.js

Node

new fields: activeNodes : object, contains a field for each nodes { idNode1 : value, idNode2 : value , ....}

inputValues: array , contains actual value at the input ( only available when nbrInputs > 0)

used fields: inputWires : Array of Array , not sure why, contains only the inputIdNodes [[idNode ]]

how to access node id:

var arrayLength = this.inputWires.length;
var inputIndex=-1;
for (var i = 0; i < arrayLength; i++) {
    if( this.inputWires[i][0]==msg.idSender ){
      inputIndex = i;
    }
}

full node ( missing activeNodes ):

:{"id":"aee3c5b8.511c38","type":"function","z":"99bba521.664458","_closeCallbacks":[null],"inputWires":[["88b73430.7748c8"]],"wires":[["d6bc2096.2943e"]],"_wireCount":1,"_wire":"d6bc2096.2943e","name":"","func":"var date = new Date(msg.payload);\n// Change the payload to be a formatted Date string\nmsg.payload = date.toString();\n// Return the message so it can be sent on\nreturn msg;","outstandingTimers":[],"outstandingIntervals":[],"script":{},"_events":{}}

If you want to run the latest code from git, here's how to get started:

1. Install grunt, the build tool

    npm install -g grunt-cli
   

2. Clone the code:

    git clone https://github.com/node-red/node-red.git
    cd node-red
   

3. Install the node-red dependencies

    npm install
   

4. Build the code

    grunt build
   

5. Run

    node red.js
