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...?
This command ...

-procName procName
The name of the procedure to create.

-conversionPattern pattern
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, colorConsole.

-appenderArgs appenderArgs
Additional arguments to apply to the appender. The argument of the option
is a list of options and their arguments.

For example

logger::utils::applyAppender -serviceCmd $log -appender console -appenderArgs {-conversionPattern {\[%M\] \[%p\] - %m}}

The usual Tcl quoting rules apply.

-levels levelList
The list of levels to apply this appender to. If not 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 ::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"
