[TYPO3-ect] Debugging with lib/div

[Stefan Geith]

Hi libdiv's !

Is there a concept about debugging or a debugObj with lib/div ?

Because it's not only usefull for development but also for the users of 
my plugins, I implemented configurable debugmessages to my plugins: e.g.
   plugin.tx_myplugin.dodebug.tmpl = 1
enables output of debugmessages for template related actions.
   plugin.tx_myplugin.dodebug.getitems = category
enables output of debugmessages for relations on field category.


Is there something available or planned for lib/div ?

I think it would be usefull to have a debugger() in tx_lib_object, like 
already controller(), configurations() and parameters()
-and/or-
a _createDebugger() in tx_lib_controller->main()


There could be a debugger Interface and a default class DebuggerVoid() 
that doesn't do any output at all, but can be replaced (via TS) by a 
real (= more sophisticated) Debugger.

I personally would like to have these functions:
   $debugger->debug($var) ... always debug $var
   $debugger->debugIfEnabled('xyz',$var)
        ... only debug if dodebug.xyz is set in TS
   $debugger->debugIfFieldIsSet('xyz',$fieldname,$var)
        ... only debug if content of dodebug.xyz==$fieldname;
        This is usefull e.g. to debug db-relations on a specific field
   $debugger->shortBacktrace($count=5,$minimize=0)
        ... that gives a condensed view of debug_backtrace
Additionally:
   $debugger->forceDebug($val) ... where $val could come from
        the flexform of the plugin:
        $val<0 => never do any debug-output
        $val=0 => debug-output depending on TS .dodebug...
        $val>0 => output every debug-message available

What do You think about this ?
