[AOLSERVER] AOLserver templating options

2009-10-26 Thread Hossein Sharifi
Hey all,

What's the current state of templating systems in AOLserver?   I've found
two:

 1) ATS:  Is it well-maintained, and can it be easily used outside of an
OpenACS installation?
 2) http://junom.com/document/twt/view/www/  - it seems to be actively
maintained given the fact that there are files in that directory created
last month, but is it easy to install? And has it been tested in a
production environment?
 3) Are there any others?

Thanks,
Hossein

ADP Master Pages is worth checking out:

It was originally developed to be used with a standalone CMS built by  
ars digita people in the bay area, and later adapted to work with aD's  
ACS (which evolved into OpenACS).


Breaking it out to run standalone again shouldn't be that difficult.
There are hook into our localization (message catalog) stuff but that  
could be ignored/ripped out.


The ATS supports master templates that appear to be much like the ADP  
Master Pages mentioned by Jeff (so i guess the similar MS technology  
referenced by that site), and has done so since oh 1998, 1999.
Actually it's a hierarchy of master templates with the top of the  
hierarchy being the master for the entire site.

I'm the maintainer. The current home for this is the tnt project:

http://www.junom.com/gitweb/gitweb.perl?p=tnt.git

It is still the view package, but requires, at least, the tnt
package for logging.

If you need help installing, please take advantage and ask here or via
direct email. Any helpful hits will be shared as better documentation.

The templating system is called tic-tac-toe,  somewhat shorter than
A templating toolkit for tcl. Although the files you saw have been
updated recently, the actual code hasn't changed. It is relatively
stable and the extension mechanism is well defined, so only actual
bugs demand attention.

But the templating system is somewhat conservative. You have to add
resources in order to access anything outside of a particular
template (the setup tcl file adds the resources).  The whole point was
a safe system where templates of unknown intent could safely be used.
So, by default, template cannot execute unsafe commands, but resources
can execute arbitrary code.

The Tic-Tac-Toe example (
http://junom.com/document/twt/view/www/tic-tac-toe.tcl ) is
non-trivial  and demonstrates many of the features. The tnt toolkit
has hundreds of examples of template files and a few examples of how
to organize a website wide templating system.

The readme file explains the language basics:
http://junom.com/document/twt/view/www/README

The template compiler is written in flex/bison so it it fast, but it
also validates syntax. When an error occurs, you get a temporary file
which ends close to the error. It is usually easy to find and fix
syntax errors. The compiled template is just tcl code, once
compiled, the compiled version remains valid until the original
template file gets a newer timestamp. (You can use touch to force a
recompile).

  3) Are there any others?

Good question.
