DESCRIPTION
This appender acts like Log::Log4perl::Appender::Screen, except that it
colorizes its output, based on the priority of the message sent.
You can configure the colors and attributes used for the different
levels, by specifying them in your configuration:
log4perl.appender.Screen.color.TRACE=cyan
log4perl.appender.Screen.color.DEBUG=bold blue
You can also specify nothing, to indicate that level should not have
coloring applied, which means the text will be whatever the default
color for your terminal is. This is the default for debug messages.
log4perl.appender.Screen.color.DEBUG=
You can use any attribute supported by Term::ANSIColor as a
configuration option.
log4perl.appender.Screen.color.FATAL=\
bold underline blink red on_white
The commonly used colors and attributes are:
attributes
BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK
colors
BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE
background colors
ON_BLACK, ON_RED, ON_GREEN, ON_YELLOW, ON_BLUE, ON_MAGENTA,
ON_CYAN, ON_WHITE
See Term::ANSIColor for a complete list, and information on which are
supported by various common terminal emulators.
The default values for these options are:
Trace
Yellow
Debug
None (whatever the terminal default is)
Info
Green
Warn
Blue
Error
Magenta
Fatal
Red
The constructor "new()" takes an optional parameter "stderr", if set to
a true value, the appender will log to STDERR. If "stderr" is set to a
false value, it will log to STDOUT. The default setting for "stderr" is
1, so messages will be logged to STDERR by default. The constructor
can also take an optional parameter "color", whose value is a hashref
of color configuration options, any levels that are not included in the
hashref will be set to their default values.
