five.pt 2.0-rc2

Five bridges and patches to use Chameleon with Zope 2.

Overview

The five.pt package brings the Chameleon template engine to the Zope 2 platform. It’s a drop-in replacement, providing bridges to the most common API.

Support for browser pages, viewlets and viewlet managers is included.

Usage

To enable Chameleon, simply include the ZCML configuration:

<include package="five.pt" />

Tempates may be instantiated directly. Here’s an example of a browser view which uses a view page template:

from Products.Five import BrowserView
from five.pt.pagetemplate import ViewPageTemplateFile

class SimpleView(BrowserView):
    index = ViewPageTemplateFile('simple.pt')

Other template classes are available, see the pagetemplate module.

For general information about Chameleon, see http://chameleon.repoze.org/.

Changelog

2.0-rc2 (2011-05-24)

• Have the base template class implement IPageTemplate from zope.pagetemplate. This interface is relied on for a number of adapter registrations and the missing interface declaration affects packages such as plone.caching. [malthe]

• Set default reload mode to the Zope 2 application server configuration’s debug_mode value. [malthe]

2.0-rc1 (2011-02-28)

• Update to Chameleon 2.0.

  This release includes many changes and is a complete rewrite of the 1.x series.

  Note that Python 2.5+ is now required. [malthe]

• Python-expressions are now subject to access-control security. [malthe]

1.3.3 - 2010-09-30

• Apply patches at import time instead of product initialisation. [wichert]

1.3.2 - 2010-09-29

• Add a same_type method to the default namespace. [wichert]

1.3.1 - 2010-09-23

• Added support for eager loading (environment variable CHAMELEON_EAGER). This flag should be passed only in development mode and will reveal any templates which do not parse. [malthe]

1.3 - 2010-09-08

• Added support for PageTemplate and ZopePageTemplate. [malthe]

1.2 - 2010-08-30

• Fixed acquisition-wrapping issue: we need to wrap with the parent to avoid a pair of template objects (original and patched).

1.1 - 2010-05-15

• Add DateTime to the base context. Fixes problems with certain ZMI pages. [wichert]

1.0 - 2010-05-13

• If template is not an acquirer, wrap it implicitly. [malthe]

• Removed unused ViewletManager ZCML handler. [malthe]

0.10 - 2010-04-20

• Improve five.grok support [fretin]

• Check if templates are acquisition-aware before trying to wrap them. This fixes problems with METAL macros in some ZMI pages. [wichert]

0.9 - 2010-04-14

• Basic support for five.grok templates. [wichert]

0.8 - 2010-01-05

• Fixed some calling convention oddity that would result in the view instance being passed doubly as the template arguments.

0.7 - 2009-05-20

• Default encoding of the base template set to UTF-8. [malthe]

• Update to latest Chameleon. [malthe]

• Patch macros attribute. [malthe]

0.6 - 2009-04-06

• Avoid another case of unconditionally attempting to Acquisition wrap template files. We do have an interface check for this. [hannosch]

0.5 - 2009-02-17

• Added test function to template context. [malthe]

• Fixed edge-case (special case?) where the view of a ViewPageTemplateFile is really only the view for a view. [malthe]

• Added patch for Products.PageTemplates.PageTemplateFile. [malthe]

• Rework the “full namespace provided to path expression” change introduced in 0.3. We no longer call the expensive locals() function but construct a minimal namespace with the context and request ourselves. [hannosch]

• If the __get__ method is called uninstantiated, just return the class itself. [malthe]

five.pt 0.4 (released 2/13/2009)

• Fixed issue where the template parameter to a viewlet manager directive was effectively ignored. [malthe]

• Fixed acquisition-wrapping issue with the (patched) bound template class (could cause infinite loop due to cyclic acquisition chain). [malthe]

• Moved evaluate_path and evaluate_exists over to z3c.pt, adding support for global path() and exists() functions for use in python: expressions to it (LP #317967). [sidnei]

five.pt 0.3 (released 12/17/2008)

• Use bobo traversal if OFS.interfaces.ITraversable interface is provided. [malthe]

• Adjusted the path expression to provide the full namespace to the render function and not just the request. This matches Zope2 behavior. [hannosch]

five.pt 0.2 (released 11/29/2008)

• From Zope 2.12 onwards, do not acquisition-wrap content provider. [malthe]

• Split out CMF-related code to separate package. [malthe]

• Compatibility changes to support Zope 2.10. [malthe]

five.pt 0.1 (released 11/19/2008)

• Initial release.

• Simplified template class inheritance. [malthe]

• Added path and exists functions to skin template namespace. [malthe]

• Added call-support for old-style classes in path expressions. [malthe]

• Added monkey-patches to replace template engine for module-level view page template instances. [malthe]

• Made EContext class more robust. [malthe]

• Register custom file-system page template class for use with CMF form controllers. [malthe]

• Register custom file-system page template class for use with CMF directory views. [malthe]

• Added meta-directives to register browser views, viewlets and viewlet managers using Chameleon templates. [malthe]

• Updated to latest API. [malthe]

• Package structure. [hannosch]
