This can be revived if anything happens, but for now, it's dead.

Great, thanks for keeping us updated.

Just to bring you up to date: As it seems, filters have been anything 
but abandoned. Only a certain method of specifying filters has been 
dropped (the PHPdocs were a bit confusing about that).



I am currently trying to convince the DH guys to provide a factory 
method for filters.

Once that is released, I should be able to provide a patch for filter 
support in no-time.

Stalling while Date_Holidays figures this out.

If it's realy depricated then it's useless to support. Havn't seen 
this, only that there are additional filters to get only the official 
holidays. Right now at least the german driver is useless for office. 
Only holidays without work are needed, so nobody makes appointments by 
mistake. No need for Girl's Day, BeerDay, WordLaughingDay and so on. 
They confuse and mess up the calendar.



As already noted, some holidays are different by state in germany. So 
having filters looks like a good solution - how should they be 
replaced? Creating a new driver, so there are at least 16 for germany?



Guess we have to figure out how the Date_Holiday project intends to 
solve this and if filters are realy droped. I hope you get an answer 
from Carsten.

Hello,



I am the one who wrote the initial patch to enable kronolith drawing 
out holidays from Date_Holidays. When I wrote that patch I was under 
the impression that filters were an abandoned concept, which was the 
reason my patch didn't feature support for filters.



I just had a look at this and found that all entry points for 
specifying filters were marked as 'deprecated'. Yet there seems to 
have been some activity regarding filters during the last two weeks. 
I'll try to contact Carsten Lucke, who is the head developer of this 
package, about this to get a final word on this feature.



Anyway, assuming filters have not been discontinued, it is still going 
to take a while for this to work, as invoking filters is a bit more 
complicated than working with drivers alone. E.g. there is no factory 
method for them and the composite filter demands filter objects, so I 
cannot just feed it some filter's names from the preference system.

Add support for different Date_Holidays_Filter_*



PEAR DATE_Holidays supports whitelist filter for holidays, right now 
there are filters for official holidays, like 
Date_Holidays_Filter_Germany_Official, 
Date_Holidays_Filter_Netherlands_Official but also for the different 
holidays in the german states like 
Date_Holidays_Filter_Germany_NorthRhineWestphalia, 
Date_Holidays_Filter_Germany_Bavaria but also others.
