zope.tal 6.0

Zope Template Application Language (TAL)

zope.tal

The Zope3 Template Attribute Languate (TAL) specifies the custom namespace and attributes which are used by the Zope Page Templates renderer to inject dynamic markup into a page. It also includes the Macro Expansion for TAL (METAL) macro language used in page assembly.

The dynamic values themselves are specified using a companion language, TALES (see the zope.tales package for more).

The reference documentation for the TAL language is available at https://pagetemplates.readthedocs.io/en/latest/tal.html

Detailed documentation for this implementation and its API is available at https://zopetal.readthedocs.io/

3.5.0 (2008-06-06)

• Remove artificial addition of a trailing newline if the output doesn’t end in one; this allows the template source to be the full specification of what should be included. (See https://bugs.launchpad.net/launchpad/+bug/218706.)

3.4.1 (2007-11-16)

• Remove unnecessary dummyengine dependency on zope.i18n to simplify distribution. The dummyengine.DummyTranslationDomain class no longer implements zope.i18n.interfaces.ITranslationDomain as a result. Installing zope.tal with easy_install or buildout no longer pulls in many unrelated distributions.
