Parse & display text from .txt
Mar 19^th, 2009, 1:47am

Hi,

I am trying to parse and display text from a .txt file. I have just begun. When I run the program it returns, "Cannot find a class or type named "GetResp"." I cannot figure out where the bug is. I am new to processing and programming so it is most likely a simple fix. Also, does anyone know of any examples that demonstrate how to parse and display text from a .txt file? Thanks.

The current code:

PFont font;
String[] data;
GetResp resp;

void setup() {
size(500,500);
background(0, 70, 120);
resp = new GetResp();
font = loadFont("Serif-24.vlw");
String[] data = loadStrings("c_p_c.txt");
}
}

void draw() {
resp.getRespo;
}

class GetResp {
int start;
int end;
String respondents;

GetResp() {
for(int i = 0; i > data.length; i++) {
int start = data[i].indexOf("'") + 4;
int end = data[i].indexOf("'", start);
}
}

void getRespo {
for(int i = 0; i > data.length; i++) {
String respondents = data[i].substring(start, end);
}
}
}

I noticed a useless '}' at the end of setup, and you have to add '()' after 'getRespo' in draw ('resp.getRespo()')and in the function declaration.

I can't run it because i have no text file but this is running :
Code:


PFont font;
String[] data;
GetResp resp;

void setup()
{
  size(500,500);
  background(0, 70, 120);
  resp = new GetResp();
  font = loadFont("Serif-24.vlw");
  String[] data = loadStrings("c_p_c.txt");
}

void draw()
{  
  resp.getRespo();
}

class GetResp
{
  int start;
  int end;
  String respondents;

  GetResp()
  {
    for(int i = 0; i > data.length; i++)
    {
	int start = data[i].indexOf("'") + 4;
	int end = data[i].indexOf("'", start);
    }
  }

  void getRespo()
  {
    for(int i = 0; i > data.length; i++)
    {
	String respondents = data[i].substring(start, end);
    }
  }
}

and if you're going to parse a text file, maybe you want to look at the split() function : http://processing.org/reference/split_.html
