module test;

import std.stdio, std.file, std.exception;

void main()
{
     string filename = "test.txt";
     enforce(filename.exists, "Umm..that file does not exist!");

     auto file = File(filename, "r");
     char[] charBuf;

     while (!file.eof())
     {
         charBuf = file.rawRead(new char[1]);

         if(!file.eof())
             process(cast(char)(charBuf[0]));
     }

     return;
}

void process(char someChar)
{
     import std.ascii : isPrintable;

     if( isPrintable(someChar) )
         writeln("found a printable character: ", someChar);
     else
         writeln("found a non printable character");
