Package: Logging
Header: Poco/ConsoleChannel.h
Description
A channel that writes to an ostream.
Only the message's text is written, followed by a newline.
Messages can be colored depending on priority. The console device must support ANSI escape codes in order to display colored messages.
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.
Similar to StreamChannel, except that a static mutex is used to protect against multiple console channels concurrently writing to the same stream.
