AnsiColorTerminalAppender appends log events to the standard output stream or the error output stream using a layout specified by the user. It also allows the color of a specific level of message to be set.

Note
This appender expects the terminal to understand the VT100 control set in order to interpret the color codes. If the terminal or console does not understand the control codes the behavior is not defined.

By default, all output is written to the console's standard output stream. The Target property can be set to direct the output to the error stream.

NOTE: This appender writes each message to the System.Console.Out or System.Console.Error that is set at the time the event is appended. Therefore it is possible to programmatically redirect the output of this appender (for example NUnit does this to capture program output). While this is the desired behavior of this appender it may have security implications in your application.

When configuring the ANSI colored terminal appender, a mapping should be specified to map a logging level to a color. For example:

<mapping><level value="ERROR" /><foreColor value="White" /><backColor value="Red" /><attributes value="Bright,Underscore" /></mapping><mapping><level value="DEBUG" /><backColor value="Green" /></mapping>

<mapping><level value="ERROR" /><foreColor value="White" /><backColor value="Red" /><attributes value="Bright,Underscore" /></mapping><mapping><level value="DEBUG" /><backColor value="Green" /></mapping>

The Level is the standard log4net logging level and ForeColor and BackColor can be any of the following values:

• Blue
  
• Green
  
• Red
  
• White
  
• Yellow
  
• Purple
  
• Cyan
  

The attributes can be any combination of the following:

• Bright
  foreground is brighter
• Dim
  foreground is dimmer
• Underscore
  message is underlined
• Blink
  foreground is blinking (does not work on all terminals)
• Reverse
  foreground and background are reversed
• Hidden
  output is hidden
• Strikethrough
  message has a line through it
