=== Syntax ===

Different approaches lead to different design decisions. Often it is the principal reason that new template systems get invented:

 * ElementBasedSyntax
 * CommentBasedSyntax
 * AttributeBasedSyntax

=== Examples ===

Some presentation systems fall neatly into the categories above. Others are less easy to classify but have a closer association to one category than the others.

 * Castalian
 * [[Cheetah]]
 * PSP (from [[Webware]])
 * [[Spyce]]

==== StructureAnnotation ====

 * ClearSilver
 * DOMTemplate (from TwistedMatrix)
 * DTML (Document Template Markup Language - see [[Zope]])
 * [[http://www.twistedmatrix.com/documents/howto/woven|Woven]] (from TwistedMatrix)
 * wt (see JonsPythonModules)
 * ZPT (Zope Page Templates - see [[Zope]])

==== Hybrids ====

 * CHTL and CGTL (from CherryPy) - PythonInWebPage and StructureAnnotation
 * PyMeld - StructureAnnotation and [[Programmatic]]
 * [[STML]] (from SkunkWeb) - PythonInWebPage, StructureAnnotation, and [[Programmatic]] being all equally apt (or equally inadequate)

==== Programmatic ====

 * PTL (from [[Quixote]])

Do you need to use full-fledged python, embedded bits of definitions but no
functions -- there is a range of options depending on your problem.
Sometimes there's no python in "the output page" -- as in raw documents put thru a filter. Or there may be limited amounts of embedded python -- as in YAPTU
and other filters. Or python may be the matrix language, with text embedded within it. Your handler code can be anything from a substituter (using, say,
regular expressions to catch things to be altered) to a mini python engine.
See [[http://pythonjournal.cognizor.com|'Python Journal 3(1)']] a feature article
that draws together several of the options above into a series on the pure-text to pure-python "dimension". See what your options are.
