DESCRIPTION¶
This package adds template based
appenders.

- %d
- Current date in yyyy/MM/dd hh:mm:ss

- %p
- Priority of logging event
- %P
- Pid of current process
- ::logger::utils::createLogProc -procName
procName ? options...?

- See ::logger::utils::createFormatCmd for the
substitutions 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,

::logger::tree::testLog
% logger::utils::applyAppender -appender console -serviceCmd $log
% ${log}::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
::logger::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"
