Hello everyone

first post here.

Im currently working on a project for my master degree at University of Aveiro (Portugal) and I could use some help since its my first time coding processing.

My app should get the RSS feed from twitter and print a line, whenever a new tweet is sent.
At the moment everything is working fine but im checking my own tweets, and only the ones that come from my user. I can get a XML file using cURL with all the tweets from my friends (wich is exactly what i need).

Code:

Get updates from users you follow in XML, authenticated: curl -u username:password hxxp://twitter.com/statuses/friends_timeline.xml 

My question is, how can Processing interact with cURL so I can authenticate and get that same result.
as long as it works its ok, doesnt really need to be cURL. I need to authenticate before i get that friends_timeline.xml

After authenticating, i can get teh friends_timeline.rss and apply it on my existing processing code.





heres my processing code so far (its speaking to arduino):
Code:

import simpleML.*;
import processing.serial.*;
XMLRequest xmlRequest;
int time;
String lasttweet;
int i;
String[] check;
String[] titulo;

Serial port;

void setup() {
  println("starting....");
  frameRate(1); 
  //xmlRequest = new XMLRequest(this,"hxxp://twitter.com/statuses/friends_timeline.rss");
  xmlRequest = new XMLRequest(this,"hxxp://twitter.com/statuses/user_timeline/23058764.rss");
  int time = 0;
  lasttweet=" ";
  port = new Serial(this, Serial.list()[1], 9600);
}

void draw() {
  background(0);
  time++;
  if (time>=4){
    xmlRequest.makeRequest();
    time=0;
  }
}

void netEvent(XMLRequest ml) {
  println("\n\nRequesting Info...\n");
  titulo = ml.getElementArray("title");
    check = match(titulo[1], lasttweet);
    if (check != null){
	println("New Tweet");
    port.write('H');
    }
    else{
	println("No Activity \n"); 
    port.write('L');
    }
    println("Tweet Anterior: " + lasttweet + "\nTweet Novo: " + titulo[1]);
    lasttweet = titulo[1];
}

 

i need a specific detail about processing and curl.
How can i make processing execute a curl command?

or

how can i authenticate to twitter using processing.

you can run external commands in java using Process / Runtime / exec.

Processing has open() to wrap this neatly. But using cURL for something Java can do natively is a bit messy (and not portable).

And I already answered, I don't see the point of duplicating the numerous threads talking about Twitter in this forum. They should get him started.

The new integrated search is a bit tricky now... You have to select (all posts) in the This post was made in the last... field, and check the Display only one result per thread checkbox otherwise we see mostly this thread...
With these settings, I see more than half a dozen of related threads, including a number using Twitter4J, some related with Arduino, etc.

Thanks Phillho you were right about the search  

Ill update this soon when i get my hands on the job.
Thank u
