DESCRIPTION
This package adds template based appenders.
::logger::utils::createFormatCmd formatString
This command translates formatString into an expandable command
string. The following strings are the known substitutions (from
log4perl) allowed to occur in the formatString:
%c Category of the logging event
%C Fully qualified name of logging event
%d Current date in yyyy/MM/dd hh:mm:ss
%H Hostname
%m Message to be logged
%M Method where logging event was issued
%p Priority of logging event
%P Pid of current process
::logger::utils::createLogProc -procName procName ?options...?

See ::logger::utils::createFormatCmd for the substitu-
tions allowed in the pattern.
-category category
The category (service).
-priority priority
The priority (level).
-outputChannel channel
channel to output on (default stdout)
::logger::utils::applyAppender -appender appenderType ?options...?
This command will create an appender for the specified logger
services. If no service is specified then the appender will be
added as the default appender for the specified levels. If no
levels are specified, then all levels are assumed.
-service loggerservices
-serviceCmd loggerserviceCmds
Name of the logger instance to modify. -serviceCmd takes
as input the return of logger::init.
-appender appenderType
Type of the appender to use. One of console, colorCon-
sole.

the pattern. If this option is not provided the default

is used.
-levels levelList

specified all levels are assumed.
Example of usage:
% set log [logger::init testLog]
::logger::tree::testLog
% logger::utils::applyAppender -appender console -serviceCmd $log
% ${log}::error "this is an error"
[2005/08/22 10:14:13] [testLog] [global] [error] this is an error
::logger::utils::autoApplyAppender command command-string log op
args...
This command is designed to be added via trace leave to calls of
logger::init. It will look at preconfigured state (via ::log-
ger::utils::applyAppender) to autocreate appenders for newly
created logger instances. It will return its argument log.
Example of usage:
logger::utils::applyAppender -appender console
set log [logger::init applyAppender-3]
${log}::error "this is an error"
