        `Pystache <http://defunkt.github.com/pystache>`__ is a Python
        implementation of `Mustache <http://mustache.github.com/>`__. Mustache
        is a framework-agnostic, logic-free templating system inspired by
        `ctemplate <http://code.google.com/p/google-ctemplate/>`__ and
        `et <http://www.ivan.fomichev.name/2008/05/erlang-template-engine-prototype.html>`__.
        Like ctemplate, Mustache "emphasizes separating logic from presentation:
        it is impossible to embed application logic in this template language."
        
        The `mustache(5) <http://mustache.github.com/mustache.5.html>`__ man
        page provides a good introduction to Mustache's syntax. For a more
        complete (and more current) description of Mustache's behavior, see the
        official `Mustache spec <https://github.com/mustache/spec>`__.
        
        Pystache is `semantically versioned <http://semver.org>`__ and can be
        found on `PyPI <http://pypi.python.org/pypi/pystache>`__. This version
        of Pystache passes all tests in `version
        1.1.2 <https://github.com/mustache/spec/tree/v1.1.2>`__ of the spec.
        
        Requirements
        ------------
        
        Pystache is tested with--
        
        -  Python 2.4 (requires simplejson `version
           2.0.9 <http://pypi.python.org/pypi/simplejson/2.0.9>`__ or earlier)
        -  Python 2.5 (requires
           `simplejson <http://pypi.python.org/pypi/simplejson/>`__)
        -  Python 2.6
        -  Python 2.7
        -  Python 3.1
        -  Python 3.2
        -  Python 3.3
        -  `PyPy <http://pypy.org/>`__
        
        `Distribute <http://packages.python.org/distribute/>`__ (the setuptools
        fork) is recommended over
        `setuptools <http://pypi.python.org/pypi/setuptools>`__, and is required
        in some cases (e.g. for Python 3 support). If you use
        `pip <http://www.pip-installer.org/>`__, you probably already satisfy
        this requirement.
        
        JSON support is needed only for the command-line interface and to run
        the spec tests. We require simplejson for earlier versions of Python
        since Python's `json <http://docs.python.org/library/json.html>`__
        module was added in Python 2.6.
        
        For Python 2.4 we require an earlier version of simplejson since
        simplejson stopped officially supporting Python 2.4 in simplejson
        version 2.1.0. Earlier versions of simplejson can be installed manually,
        as follows:
        
        ::
        
            pip install 'simplejson<2.1.0'
        
        Official support for Python 2.4 will end with Pystache version 0.6.0.
        
        Install It
        ----------
        
        ::
        
            pip install pystache
        
        And test it--
        
        ::
        
            pystache-test
        
        To install and test from source (e.g. from GitHub), see the Develop
        section.
        
        Use It
        ------
        
        ::
        
            >>> import pystache
            >>> print pystache.render('Hi {{person}}!', {'person': 'Mom'})
            Hi Mom!
        
        You can also create dedicated view classes to hold your view logic.
        
        Here's your view class (in .../examples/readme.py):
        
        ::
        
            class SayHello(object):
                def to(self):
                    return "Pizza"
        
        Instantiating like so:
        
        ::
        
            >>> from pystache.tests.examples.readme import SayHello
            >>> hello = SayHello()
        
        Then your template, say\_hello.mustache (by default in the same
        directory as your class definition):
        
        ::
        
            Hello, {{to}}!
        
        Pull it together:
        
        ::
        
            >>> renderer = pystache.Renderer()
            >>> print renderer.render(hello)
            Hello, Pizza!
        
        For greater control over rendering (e.g. to specify a custom template
        directory), use the ``Renderer`` class like above. One can pass
        attributes to the Renderer class constructor or set them on a Renderer
        instance. To customize template loading on a per-view basis, subclass
        ``TemplateSpec``. See the docstrings of the
        `Renderer <https://github.com/defunkt/pystache/blob/master/pystache/renderer.py>`__
        class and
        `TemplateSpec <https://github.com/defunkt/pystache/blob/master/pystache/template_spec.py>`__
        class for more information.
        
        You can also pre-parse a template:
        
        ::
        
            >>> parsed = pystache.parse(u"Hey {{#who}}{{.}}!{{/who}}")
            >>> print parsed
            [u'Hey ', _SectionNode(key=u'who', index_begin=12, index_end=18, parsed=[_EscapeNode(key=u'.'), u'!'])]
        
        And then:
        
        ::
        
            >>> print renderer.render(parsed, {'who': 'Pops'})
            Hey Pops!
            >>> print renderer.render(parsed, {'who': 'you'})
            Hey you!
        
        Python 3
        --------
        
        Pystache has supported Python 3 since version 0.5.1. Pystache behaves
        slightly differently between Python 2 and 3, as follows:
        
        -  In Python 2, the default html-escape function ``cgi.escape()`` does
           not escape single quotes. In Python 3, the default escape function
           ``html.escape()`` does escape single quotes.
        -  In both Python 2 and 3, the string and file encodings default to
           ``sys.getdefaultencoding()``. However, this function can return
           different values under Python 2 and 3, even when run from the same
           system. Check your own system for the behavior on your system, or do
           not rely on the defaults by passing in the encodings explicitly (e.g.
           to the ``Renderer`` class).
        
        Unicode
        -------
        
        This section describes how Pystache handles unicode, strings, and
        encodings.
        
        Internally, Pystache uses `only unicode
        strings <http://docs.python.org/howto/unicode.html#tips-for-writing-unicode-aware-programs>`__
        (``str`` in Python 3 and ``unicode`` in Python 2). For input, Pystache
        accepts both unicode strings and byte strings (``bytes`` in Python 3 and
        ``str`` in Python 2). For output, Pystache's template rendering methods
        return only unicode.
        
        Pystache's ``Renderer`` class supports a number of attributes to control
        how Pystache converts byte strings to unicode on input. These include
        the ``file_encoding``, ``string_encoding``, and ``decode_errors``
        attributes.
        
        The ``file_encoding`` attribute is the encoding the renderer uses to
        convert to unicode any files read from the file system. Similarly,
        ``string_encoding`` is the encoding the renderer uses to convert any
        other byte strings encountered during the rendering process into unicode
        (e.g. context values that are encoded byte strings).
        
        The ``decode_errors`` attribute is what the renderer passes as the
        ``errors`` argument to Python's built-in unicode-decoding function
        (``str()`` in Python 3 and ``unicode()`` in Python 2). The valid values
        for this argument are ``strict``, ``ignore``, and ``replace``.
        
        Each of these attributes can be set via the ``Renderer`` class's
        constructor using a keyword argument of the same name. See the Renderer
        class's docstrings for further details. In addition, the
        ``file_encoding`` attribute can be controlled on a per-view basis by
        subclassing the ``TemplateSpec`` class. When not specified explicitly,
        these attributes default to values set in Pystache's ``defaults``
        module.
        
        Develop
        -------
        
        To test from a source distribution (without installing)--
        
        ::
        
            python test_pystache.py
        
        To test Pystache with multiple versions of Python (with a single
        command!), you can use `tox <http://pypi.python.org/pypi/tox>`__:
        
        ::
        
            pip install 'virtualenv<1.8'  # Version 1.8 dropped support for Python 2.4.
            pip install 'tox<1.4'  # Version 1.4 dropped support for Python 2.4.
            tox
        
        If you do not have all Python versions listed in ``tox.ini``--
        
        ::
        
            tox -e py26,py32  # for example
        
        The source distribution tests also include doctests and tests from the
        Mustache spec. To include tests from the Mustache spec in your test
        runs:
        
        ::
        
            git submodule init
            git submodule update
        
        The test harness parses the spec's (more human-readable) yaml files if
        `PyYAML <http://pypi.python.org/pypi/PyYAML>`__ is present. Otherwise,
        it parses the json files. To install PyYAML--
        
        ::
        
            pip install pyyaml
        
        To run a subset of the tests, you can use
        `nose <http://somethingaboutorange.com/mrl/projects/nose/0.11.1/testing.html>`__:
        
        ::
        
            pip install nose
            nosetests --tests pystache/tests/test_context.py:GetValueTests.test_dictionary__key_present
        
        Using Python 3 with Pystache from source
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        Pystache is written in Python 2 and must be converted to Python 3 prior
        to using it with Python 3. The installation process (and tox) do this
        automatically.
        
        To convert the code to Python 3 manually (while using Python 3)--
        
        ::
        
            python setup.py build
        
        This writes the converted code to a subdirectory called ``build``. By
        design, Python 3 builds
        `cannot <https://bitbucket.org/tarek/distribute/issue/292/allow-use_2to3-with-python-2>`__
        be created from Python 2.
        
        To convert the code without using setup.py, you can use
        `2to3 <http://docs.python.org/library/2to3.html>`__ as follows (two
        steps)--
        
        ::
        
            2to3 --write --nobackups --no-diffs --doctests_only pystache
            2to3 --write --nobackups --no-diffs pystache
        
        This converts the code (and doctests) in place.
        
        To ``import pystache`` from a source distribution while using Python 3,
        be sure that you are importing from a directory containing a converted
        version of the code (e.g. from the ``build`` directory after
        converting), and not from the original (unconverted) source directory.
        Otherwise, you will get a syntax error. You can help prevent this by not
        running the Python IDE from the project directory when importing
        Pystache while using Python 3.
        
        Mailing List
        ------------
        
        There is a `mailing list <http://librelist.com/browser/pystache/>`__.
        Note that there is a bit of a delay between posting a message and seeing
        it appear in the mailing list archive.

        History
        =======
        
        **Note:** Official support for Python 2.4 will end with Pystache version

        0.5.0 (2012-04-03)
        ------------------
        
        This version represents a major rewrite and refactoring of the code base
        that also adds features and fixes many bugs. All functionality and
        nearly all unit tests have been preserved. However, some backwards
        incompatible changes to the API have been made.
        
        Below is a selection of some of the changes (not exhaustive).
        
        Highlights:
        
        -  Pystache now passes all tests in version 1.0.3 of the `Mustache
           spec <https://github.com/mustache/spec>`__. [pvande]
        -  Removed View class: it is no longer necessary to subclass from View
           or from any other class to create a view.
        -  Replaced Template with Renderer class: template rendering behavior
           can be modified via the Renderer constructor or by setting attributes
           on a Renderer instance.
        -  Added TemplateSpec class: template rendering can be specified on a
           per-view basis by subclassing from TemplateSpec.
        -  Introduced separation of concerns and removed circular dependencies
           (e.g. between Template and View classes, cf. `issue
           #13 <https://github.com/defunkt/pystache/issues/13>`__).
        -  Unicode now used consistently throughout the rendering process.
        -  Expanded test coverage: nosetests now runs doctests and ~105 test
           cases from the Mustache spec (increasing the number of tests from 56
           to ~315).
        -  Added a rudimentary benchmarking script to gauge performance while
           refactoring.
        -  Extensive documentation added (e.g. docstrings).
        
        Other changes:
        
        -  Added a command-line interface. [vrde]
        -  The main rendering class now accepts a custom partial loader (e.g. a
           dictionary) and a custom escape function.
        -  Non-ascii characters in str strings are now supported while
           rendering.
        -  Added string encoding, file encoding, and errors options for decoding
           to unicode.
        -  Removed the output encoding option.
        -  Removed the use of markupsafe.
        
        Bug fixes:
        
        -  Context values no longer processed as template strings.
           [jakearchibald]
        -  Whitespace surrounding sections is no longer altered, per the spec.
           [heliodor]
        -  Zeroes now render correctly when using PyPy. [alex]
        -  Multline comments now permitted. [fczuardi]
        -  Extensionless template files are now supported.
        -  Passing ``**kwargs`` to ``Template()`` no longer modifies the
           context.
        -  Passing ``**kwargs`` to ``Template()`` with no context no longer
           raises an exception.
