lgr

Lgr is yet another Java Logging Framework

Why another Java Logging Framework?

Because, quite frankly, most logging frameworks are over-engineered and hard to use. Logging should be a "no-brainer" and not yet another tool that requires a couple of hours/days to set up.

Installation

1. Copy Lgr.java into your project.

Usage

import at.int32.lgr;

Lgr.i("Hello World!");
Lgr.w("This is a warning: %s", "Don't try this at home.");

try {
  throw new IllegalArgumentException("error");
} catch (Exception e) {
  Lgr.e(e, "This is a custom error message: %s", "Quite the failure.");
}

which will produce the following result:

2018-01-12 13:02:51:056 [INFO]	Hello World!
2018-01-12 13:02:51:110 [WARN]	This is a warning: Don't try this at home.
2018-01-12 13:02:51:113 [ERROR]	This is a custom error message: Quite the failure. java.lang.IllegalArgumentException: error
	at at.int32.lgr.App.main(App.java:9)

Loggers

By default Lgr will print to System.out using the integrated Lgr.ConsoleLgrclass.

Following loggers are already contained within Lgr:

• Lgr.ConsoleLgr
• Lgr.FileLgr

To write your own custom Lgr simply implemented the Lgr.ILgr interface.

To use a different, multiple, or even custom Loggers simply do the following:

Lgr.set(new ConsoleLgr(), new FileLgr("output.log"), new MyCustomLgr());

Format

To change the desired output format use the static Lgr.FORMAT field. By default it's formated like this:

//Example: 2018-01-12 13:02:51:056 [INFO]	Hello World!
%1$tY-%1$tm-%1$td %1$tH:%1$tM:%1$tS:%1$tL [%2$s]\t%3$s

Example: 2018-01-12 13:02:51:056 [INFO] Hello World!

• %1 = Date (java.util.Date)
• %2 = Level (Lgr.Level)
• %3 = Message (System.String)
