class WindowsColorConsoleChannel

File Information

Library: Foundation
Package: Logging
Header: Poco/WindowsConsoleChannel.h

Description

A channel that writes to the Windows console.

Only the message's text is written, followed by a newline.

Log messages are assumed to be UTF-8 encoded, and are converted to UTF-16 prior to writing them to the console. This is the main difference to the ConsoleChannel class, which cannot handle UTF-8 encoded messages on Windows.

Messages can be colored depending on priority.

To enable message coloring, set the "enableColors" property to true (default). Furthermore, colors can be configured by setting the following properties (default values are given in parenthesis):

  • traceColor (gray)
  • debugColor (gray)
  • informationColor (default)
  • noticeColor (default)
  • warningColor (yellow)
  • errorColor (lightRed)
  • criticalColor (lightRed)
  • fatalColor (lightRed)

The following color values are supported:

  • default
  • black
  • red
  • green
  • brown
  • blue
  • magenta
  • cyan
  • gray
  • darkgray
  • lightRed
  • lightGreen
  • yellow
  • lightBlue
  • lightMagenta
  • lightCyan
  • white

Chain this channel to a FormattingChannel with an appropriate Formatter to control what is contained in the text.

Only available on Windows platforms.
