ofDirList - July 18th 2007 - by Theodore Watson

Installation:
1 Copy ofDirList.h and ofDirList.cpp to your ofAddons folder.
2 Add #include "ofDirList.h" to ofAddons.h
3 Add ofDirList.h and ofDirList.cpp to IDE

Changes:
1 Now takes string type as argument
2 Fixed wildcard * for allowing all extensions
3 Extensions are now case insensitive
4 reset() function to clear extension list

Example Usage:

////////////////////////////////////////////////
ofDirList DIR;

//Allow only certain files
//by specifying extension
//Extensions are not case sensitive
//so 'mov' allows both 'mov' and 'MOV'
//To include all files either don't
//call allowExt or specify the wildcard
// '*'

DIR.allowExt("mov");
DIR.allowExt("jpg");

//if you wish to keep the console quiet
DIR.setVerbose(false);

//now lets list the directory
//listDir returns number of files found
//with the specified extension
int numFiles = DIR.listDir("images/");

//you can now iterate through the files as you like
for(int i = 0; i < numFiles; i++){
  printf("name is %s - path is %s \n", DIR.getName(i), DIR.getPath(i) );
}

//if you want to reuse ofDirList for different files
//call reset(); to clear the allowed extensions
