five.pt 2.2.2

Five bridges and patches to use Chameleon with Zope.

Overview

This package brings the Chameleon template engine to the Zope application server.

It works using monkey-patching onto the existing API (specifically, the TALInterpreter and PageTemplate classes). In simple terms, what the patching does is to replace the TAL interpreter class and make sure that the so-called "cooking" routine uses the Chameleon parser and compiler instead of the zope.* reference implementation.

Usage

To enable Chameleon, configure the package using ZCML:

<include package="five.pt" />

For more information on Chameleon, see http://www.pagetemplates.org/.

Changelog

2.2.2 (2014-04.15)

  • Fix test. [davisagli]

2.2.1 (2012-01-08)

Features:

  • Whitespace between attributes is now reduced to a single whitespace character.

Bugfixes:

  • The path traverser now correctly renders callables, applying the template namespace as keyword arguments. Previously, only the request name would be passed.
  • The content provider expression now correctly applies TAL namespace data.
  • Avoid duplicate HTML decoding. This fixes an issue which was introduced because newer Chameleon releases decode all expression inputs by default.

2.2.0 (2011-10-10)

  • Update implementation to use component-based template engine configuration, plugging directly into the Zope Toolkit framework.
  • Declare RepeatItem as public object with allowed subobjects [leorochael]
  • Bump minimum versions of dependencies z3c.pt and sourcecodegen to fix lp#853731 and lp#848200. [leorochael]
  • Fixed encoding issue with restricted Python expression. The Python 2.4 AST parser does not accept unicode input and the expression string must be explicitly encoded to a byte string. [malthe]

2.1.5 (2011-08-11)

  • Reuse template instance on cook. [malthe]
  • Use the template source string available in the _text attribute instead of reading the file (again). [leorochael, malthe]
  • Use secure moduler importer for both Zope 2 and 3 templates. This fixes issue #34. [malthe]

2.1.4 (2011-07-28)

  • Upgrade to newest Zope integration package.

2.1.3 (2011-07-23)

  • Fixed issue with traversal and dictionary optimization (the optimization has been removed). [malthe]
  • Fixed compatibility issue with the UnauthorizedBinding class and traversal. [malthe]

2.1.2 (2011-07-21)

  • Wire in restricted python builtins as imports. Previously these were added to the dynamic context. [malthe]
  • Use the Python expression from the z3c.pt package for the trusted page template engine. This difference between this and the standard Python expression from Chameleon is that the pipe character ("|") has the meaning of fallback in Chameleon, but not in the reference ZPT implementation (where it's only available for path expressions). [malthe]

2.1.1 (2011-07-15)

  • Added builtins from RestrictedPython to context for Zope 2 templates.

    This fixes name error issues on templates that use one or more utility function builtins normally available to Python expressions in restricted mode. [malthe]

2.1 (2011-07-14)

  • Point release.
  • Use trusted path expression for trusted expression engine. [malthe]
  • Fixed template context issues where a request would be required by the path expression compiler but not provided (typically when in a situation where the user is unauthorized to view content). [malthe]

2.1-rc1 (2011-07-14)

  • Major architectural change.

    The package no longer contains own template classes; instead, patches are made to switch from the reference TAL interpreter to the Chameleon TAL compiler. [malthe]

2.0-rc3 (2011-07-07)

  • Refactor custom Python expression implementation to use the parse method. This builds directly on the base implementation and its behavior. [malthe]

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]
