DESCRIPTION

38       This appender acts like Log::Log4perl::Appender::Screen, except that it
39       colorizes its output, based on the priority of the message sent.
40
41       You can configure the colors and attributes used for the different
42       levels, by specifying them in your configuration:
43
44           log4perl.appender.Screen.color.TRACE=cyan
45           log4perl.appender.Screen.color.DEBUG=bold blue
46
47       You can also specify nothing, to indicate that level should not have
48       coloring applied, which means the text will be whatever the default
49       color for your terminal is.  This is the default for debug messages.
50
51           log4perl.appender.Screen.color.DEBUG=
52
53       You can use any attribute supported by Term::ANSIColor as a
54       configuration option.
55
56           log4perl.appender.Screen.color.FATAL=\
57               bold underline blink red on_white
58
59       The commonly used colors and attributes are:
60
61       attributes
62           BOLD, DARK, UNDERLINE, UNDERSCORE, BLINK
63
64       colors
65           BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE
66
67       background colors
68           ON_BLACK, ON_RED, ON_GREEN, ON_YELLOW, ON_BLUE, ON_MAGENTA,
69           ON_CYAN, ON_WHITE
70
71       See Term::ANSIColor for a complete list, and information on which are
72       supported by various common terminal emulators.
73
74       The default values for these options are:
75
76       Trace
77           Yellow
78
79       Debug
80           None (whatever the terminal default is)
81
82       Info
83           Green
84
85       Warn
86           Blue
87
88       Error
89           Magenta
90
91       Fatal
92           Red
93
94       The constructor "new()" takes an optional parameter "stderr", if set to
95       a true value, the appender will log to STDERR. If "stderr" is set to a
96       false value, it will log to STDOUT. The default setting for "stderr" is
97       1, so messages will be logged to STDERR by default.  The constructor
98       can also take an optional parameter "color", whose value is a  hashref
99       of color configuration options, any levels that are not included in the
100       hashref will be set to their default values.
101
102   Using ScreenColoredLevels on Windows
103       Note that if you're using this appender on Windows, you need to fetch
104       Win32::Console::ANSI from CPAN and add
105
106           use Win32::Console::ANSI;
107
108       to your script.
