[Zope] Re: Java re-invents DTML :-)

[Kevin Carlson]

Come on folks.  There's nothing wrong with supporting two templating 
languages.  Quite honestly, dtml is much easier to learn for most and 
has it's place in application development -- just as ZPT does.

One simple reason that dtml should be supported (in addition to the fact 
that it works well) is for the support of existing Zope applications.  
If Zope was to suddenly stop supporting dtml, it would cause many, many 
people a lot of work if they wanted to get features available in a new 
version of Zope.  The argument could be made that they "need" to migrate 
to zpt in the opinion of some, but that is not good business for Zope.

I don't know why there are a zealous few out there that want to 
eliminate dtml from Zope.  If you don't like it, don't use it.  This is 
technology folks, not religion. Oh yeah, my bad -- for some, technology 
is religion. ;-) 

With the proper discipline, dtml or zpt along with python can help 
achieve good separation between logic and content.  I've seen this same 
argument over the last 20 years whether the language was C, C++, Java, 
Prolog, Basic, Cobol, Pascal, etc.  Trust me, crappy coding knows no 
language barrier.

DTML and ZPT both have a place in Zope.  Deciding which one to use 
should be left up to the individual.
