StackLogger

This Java project improves the usefulness of System.out and System.err print methods by logging the run-time stack.

Requirements

• Java 8 or newer
• IntelliJ IDEA 2019.1 or newer (optional)

How to Install

To use this class, simply import it (if necessary) and put these two lines in your main method:

StackLogger infoLogger = new StackLogger(System.out, "information.txt", "out");
System.setOut(infoLogger);
StackLogger errorLogger = new StackLogger(System.err, "errors.txt", "err");
System.setErr(errorLogger);

If you do not wish to log to a file, simply pass null as the second parameter, like so:

StackLogger infoLogger = new StackLogger(System.out, null, "out");
System.setOut(infoLogger);
StackLogger errorLogger = new StackLogger(System.err, null, "err");
System.setErr(errorLogger);

When done using the logger (like when exiting your application), you can simply call the close method:

infoLogger.close();
errorLogger.close();

You can also run the included Main class for an example of the Stack Logger.
