import com.chilkatsoft.chilkat2.Log;

public class ChilkatExample {

    public static void main(String[] args) {
        Log log = new Log();

        // Initialize the log object with an initial context tag:
        log.clear("myLog");

        // Add some information..
        log.logInfo("Hello, I'm here...");

        // Open a sub-context
        log.enterContext("abc");

        // New information is now logged within the "abc" context.
        log.logInfo("This is inside the abc context");
        log.logError("File not found.");

        // Perhaps open a new context...
        log.enterContext("fileInfo");
        log.logData("filename", "something.txt");
        log.logData("path", "/somedir/xyz");
        log.leaveContext();

        // Close the "abc" context.
        log.leaveContext();

        // Examine the content of the log:
        System.out.println(log.getLastErrorText());

        // This is the output:

        // myLog:
        //   Hello, I'm here...
        //   abc:
        //     This is inside the abc context
        //     File not found.
        //     fileInfo:
        //       filename: something.txt
        //       path: /somedir/xyz
        //     --fileInfo
        //   --abc
        // --myLog
