Description: Overview
        ========
        
        Chameleon is an HTML/XML template engine for `Python
        <http://www.python.org>`_. It uses the *page templates* language.
        
        You can use it in any Python web application with just about any
        version of Python (2.5 and up, including 3.x and `pypy
        <http://pypy.org>`_).

        Changes
        =======
        
        2.1 (2011-07-25)
        ----------------
        
        Features:
        
        - Expression interpolation (using the ``${...}`` operator and
          previously also ``$identifier``) now requires braces everywhere
          except inside the ``string:`` expression type.
        
          This change is motivated by a number of legacy templates in which
          the interpolation format without braces ``$identifier`` appears as
          text.
        
        2.0.2 (2011-07-25)
        ------------------
        
        Bugfixes:
        
        - Don't use dynamic variable scope for lambda-scoped variables (#27).
        
        - Avoid duplication of exception class and message in traceback.
        
        - Fixed issue where a ``metal:fill-slot`` would be ignored if a macro
          was set to be used on the same element (#16).
        
        2.0.1 (2011-07-23)
        ------------------
        
        Bugfixes:
        
        - Fixed issue where global variable definition from macro slots would
          fail (they would instead be local). This also affects error
          reporting from inside slots because this would be recorded
          internally as a global.
        
        - Fixed issue with template cache digest (used for filenames); modules
          are now invalidated whenever any changes are made to the
          distribution set available (packages on ``sys.path``).
        
        - Fixed exception handler to better let exceptions propagate through
          the renderer.
        
        - The disk-based module compiler now mangles template source filenames
          such that the output Python module is valid and at root level (dots
          and hyphens are replaced by an underscore). This fixes issue #17.
        
        - Fixed translations (i18n) on Python 2.5.
        
        2.0 (2011-07-14)
        ----------------
        
        - Point release.
        
        2.0-rc14 (2011-07-13)
        ---------------------
        
        Bugfixes:
        
        - The tab character (``\t``) is now parsed correctly when used inside
          tags.
        
        Features:
        
        - The ``RepeatDict`` class now works as a proxy behind a seperate
          dictionary instance.
        
        - Added template constructor option ``keep_body`` which is a flag
          (also available as a class attribute) that controls whether to save
          the template body input in the ``body`` attribute.
        
          This is disabled by default, unless debug-mode is enabled.
        
        - The page template loader class now accepts an optional ``formats``
          argument which can be used to select an alternative template class.
        
        2.0-rc13 (2011-07-07)
        ---------------------
        
        Bugfixes:
        
        - The backslash character (followed by optional whitespace and a line
          break) was not correctly interpreted as a continuation for Python
          expressions.
        
        Features:
        
        - The Python expression implementation is now more flexible for
          external subclassing via a new ``parse`` method.
        
        2.0-rc12 (2011-07-04)
        ---------------------
        
        Bugfixes:
        
        - Initial keyword arguments passed to a template now no longer "leak"
          into the template variable space after a macro call.
        
        - An unexpected end tag is now an unrecoverable error.
        
        Features:
        
        - Improve exception output.
        
        2.0-rc11 (2011-05-26)
        ---------------------
        
        Bugfixes:
        
        - Fixed issue where variable names that begin with an underscore were
          seemingly allowed, but their use resulted in a compiler error.
        
        Features:
        
        - Template variable names are now allowed to be prefixed with a single
          underscore, but not two or more (reserved for internal use).
        
          Examples of valid names::
        
            item
            ITEM
            _item
            camelCase
            underscore_delimited
            help
        
        - Added support for Genshi's comment "drop" syntax::
        
            <!--! This comment will be dropped -->
        
          Note the additional exclamation (!) character.
        
          This fixes addresses issue #10.
        
        2.0-rc10 (2011-05-24)
        ---------------------
        
        Bugfixes:
        
        - The ``tal:attributes`` statement now correctly operates
          case-insensitive. The attribute name given in the statement will
          replace an existing attribute with the same name, without respect to
          case.
        
        Features:
        
        - Added ``meta:interpolation`` statement to control expression
          interpolation setting.
        
          Strings that disable the setting: ``"off"`` and ``"false"``.
          Strings that enable the setting: ``"on"`` and ``"true"``.
        
        - Expression interpolation now works inside XML comments.
        
        2.0-rc9 (2011-05-05)
        --------------------
        
        Features:
        
        - Better debugging support for string decode and conversion. If a
          naive join fails, each element in the output will now be attempted
          coerced to unicode to try and trigger the failure near to the bad
          string.
        
        2.0-rc8 (2011-04-11)
        --------------------
        
        Bugfixes:
        
        - If a macro defines two slots with the same name, a caller will now
          fill both with a single usage.
        
        - If a valid of ``None`` is provided as the translation function
          argument, we now fall back to the class default.
        
        2.0-rc7 (2011-03-29)
        --------------------
        
        Bugfixes:
        
        - Fixed issue with Python 2.5 compatibility AST. This affected at
          least PyPy 1.4.
        
        Features:
        
        - The ``auto_reload`` setting now defaults to the class value; the
          base template class gives a default value of
          ``chameleon.config.AUTO_RELOAD``. This change allows a subclass to
          provide a custom default value (such as an application-specific
          debug mode setting).
        
        
        2.0-rc6 (2011-03-19)
        --------------------
        
        Features:
        
        - Added support for ``target_language`` keyword argument to render
          method. If provided, the argument will be curried onto the
          translation function.
        
        Bugfixes:
        
        - The HTML entities 'lt', 'gt' and 'quot' appearing inside content
          subtition expressions are now translated into their native character
          values. This fixes an issue where you could not dynamically create
          elements using the ``structure`` (which is possible in ZPT). The
          need to create such structure stems from the lack of an expression
          interpolation operator in ZPT.
        
        - Fixed duplicate file pointer issue with test suite (affected Windows
          platforms only). This fixes issue #9.
          [oliora]
        
        - Use already open file using ``os.fdopen`` when trying to write out
          the module source. This fixes LP #731803.
        
        
        2.0-rc5 (2011-03-07)
        --------------------
        
        Bugfixes:
        
        - Fixed a number of issues concerning the escaping of attribute
          values:
        
          1) Static attribute values are now included as they appear in the
             source.
        
             This means that invalid attribute values such as ``"true &&
             false"`` are now left alone. It's not the job of the template
             engine to correct such markup, at least not in the default mode
             of operation.
        
          2) The string expression compiler no longer unescapes
             values. Instead, this is left to each expression
             compiler. Currently only the Python expression compiler unescapes
             its input.
        
          3) The dynamic escape code sequence now correctly only replaces
             ampersands that are part of an HTML escape format.
        
        Imports:
        
        - The page template classes and the loader class can now be imported
          directly from the ``chameleon`` module.
        
        Features:
        
        - If a custom template loader is not provided, relative paths are now
          resolved using ``os.abspath`` (i.e. to the current working
          directory).
        
        - Absolute paths are normalized using ``os.path.normpath`` and
          ``os.path.expanduser``. This ensures that all paths are kept in
          their "canonical" form.
        
        
        2.0-rc4 (2011-03-03)
        --------------------
        
        Bugfixes:
        
        - Fixed an issue where the output of an end-to-end string expression
          would raise an exception if the expression evaluated to ``None`` (it
          should simply output nothing).
        
        - The ``convert`` function (which is configurable on the template
          class level) now defaults to the ``translate`` function (at
          run-time).
        
          This fixes an issue where message objects were not translated (and
          thus converted to a string) using the a provided ``translate``
          function.
        
        - Fixed string interpolation issue where an expression immediately
          succeeded by a right curly bracket would not parse.
        
          This fixes issue #5.
        
        - Fixed error where ``tal:condition`` would be evaluated after
          ``tal:repeat``.
        
        Features:
        
        - Python expression is now a TALES expression. That means that the
          pipe operator can be used to chain two or more expressions in a
          try-except sequence.
        
          This behavior was ported from the 1.x series. Note that while it's
          still possible to use the pipe character ("|") in an expression, it
          must now be escaped.
        
        - The template cache can now be shared by multiple processes.
        
        
        2.0-rc3 (2011-03-02)
        --------------------
        
        Bugfixes:
        
        - Fixed ``atexit`` handler.
        
          This fixes issue #3.
        
        - If a cache directory is specified, it will now be used even when not
          in debug mode.
        
        - Allow "comment" attribute in the TAL namespace.
        
          This fixes an issue in the sense that the reference engine allows
          any attribute within the TAL namespace. However, only "comment" is
          in common use.
        
        - The template constructor now accepts a flag ``debug`` which puts the
          template *instance* into debug-mode regardless of the global
          setting.
        
          This fixes issue #1.
        
        Features:
        
        - Added exception handler for exceptions raised while evaluating an
          expression.
        
          This handler raises (or attempts to) a new exception of the type
          ``RenderError``, with an additional base class of the original
          exception class. The string value of the exception is a formatted
          error message which includes the expression that caused the
          exception.
        
          If we are unable to create the exception class, the original
          exception is re-raised.
        
        2.0-rc2 (2011-02-28)
        --------------------
        
        - Fixed upload issue.
        
        2.0-rc1 (2011-02-28)
        --------------------
        
        - Initial public release. See documentation for what's new in this
          series.
