associated with it. It really needs it because of the behavior of Cdk. Cdk
was written using curses; and one of the behaviors set when using Cdk is
that </R>noecho<!R> is turned on. This means that whenever a character is printed
to the screen using </R>print<!R> or </R>printf<!R> they won't show up. This means another
method of diagnostics must be provided.
</U>Cdk::Diag Module:<!U>
The Cdk::Diag module currently only has one method: Log. It writes to the
log file if diagnostics has been turned on. If diagnostics has been turned
on, the performance of the Cdk Perl script will take a severe performance
hit, depending on how many diagnostics are turned on.
</U>Turning on the Diagnostics:<!U>
To turn the diagnostics on, there is an environment variable called
</R>CDKDIAG<!R> which needs to be set. This currently only really supports one
value: </B>ALL<!B>. There is work being done right now so diagnostics can be turned
on by method name, class name, required values only, default values only,
methods called....
</U>Diagnostic File:<!U>
The default diagnostic filename is </R>cdkdiag.log<!R> but can be changed by
setting the environment variable </R>CDKLOGFILE<!R>.
