Package org.apache.tools.ant.listener

## Class AnsiColorLogger

- java.lang.Object
- - org.apache.tools.ant.DefaultLogger
  - - org.apache.tools.ant.listener.AnsiColorLogger

- All Implemented Interfaces:
    `java.util.EventListener`, `BuildListener`, `BuildLogger`

      public class AnsiColorLogger
      extends DefaultLogger

  Uses ANSI Color Code Sequences to colorize messages sent to the console.

  If used with the -logfile option, the output file will contain all the necessary escape codes to display the text in colorized mode when displayed in the console using applications like cat, more, etc.

  This is designed to work on terminals that support ANSI color codes. It works on XTerm, ETerm, Mindterm, etc. It also works on Win9x (with ANSI.SYS loaded.)

  NOTE: It doesn't work on WinNT's COMMAND.COM even with ANSI.SYS loaded.

  The default colors used for differentiating the message levels can be changed by editing the /org/apache/tools/ant/listener/defaults.properties file. This file contains 5 key/value pairs:

       AnsiColorLogger.ERROR_COLOR=2;31
       AnsiColorLogger.WARNING_COLOR=2;35
       AnsiColorLogger.INFO_COLOR=2;36
       AnsiColorLogger.VERBOSE_COLOR=2;32
       AnsiColorLogger.DEBUG_COLOR=2;34

  Another option is to pass a system variable named ant.logger.defaults, with value set to the path of the file that contains user defined Ansi Color Codes, to the java command using -D option.

  To change these colors use the following chart:
