Java Colored Debug Printer (JCDP) offers you an easy syntax to print messages with a colored font or background on a terminal. It also provides custom levels of debug logging.

Example

The screenshots above were produced by running this example code:

// =============================
// Example of a terminal Printer
// =============================

Printer p = new Printer.Builder(Types.TERM).build();
p.println(p);
p.println("This is a normal message.");
p.errorPrintln("This is an error message.");
p.debugPrintln("This debug message is always printed.");
p = new Printer.Builder(Types.TERM).level(1).timestamping(false).build();
p.println(p);
p.debugPrintln("This is printed because its level is <= 1", 1);
p.debugPrintln("This isn't printed because its level is > 1", 2);
p.setLevel(2);
p.debugPrintln("Now this is printed because its level is <= 2", 2);

// =======================================================
// Example of a Colored terminal Printer (WINDOWS or UNIX)
// =======================================================

ColoredPrinter cp = new ColoredPrinter.Builder(1, false)
                        .foreground(FColor.WHITE).background(BColor.BLUE)   //setting format
                        .build();

//printing according to that format
cp.println(cp);
cp.setAttribute(Attribute.REVERSE);
cp.println("This is a normal message (with format reversed).");

//resetting the terminal to its default colors
cp.clear();
cp.print(cp.getDateFormatted(), Attribute.NONE, FColor.CYAN, BColor.BLACK);
cp.debugPrintln(" This debug message is always printed.");
cp.clear();
cp.print("This example used JCDP 1.25   ");

//temporarily overriding that format
cp.print("\tMADE ", Attribute.BOLD, FColor.YELLOW, BColor.GREEN);
cp.print("IN PORTUGAL\t\n", Attribute.BOLD, FColor.YELLOW, BColor.RED);
cp.println("I hope you find it useful ;)");

cp.clear(); //don't forget to clear the terminal's format before exiting
