+`Pystache <https://github.com/defunkt/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
+
+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'
+
+Install It
+----------
+
+::
+
+ pip install pystache
+ 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; whereas 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 tox
+ 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
+
+**Running Pystache from source with Python 3.** Pystache is written in
+Python 2 and must be converted with
+`2to3 <http://docs.python.org/library/2to3.html>`_ prior to running
+under Python 3. The installation process (and tox) do this conversion
+automatically.
+
+To ``import pystache`` from a source distribution while using Python 3,
+be sure that you are importing from a directory containing a converted
+version (e.g. from your site-packages directory after manually
+installing) and not from the original source directory. Otherwise, you
+will get a syntax error. You can help ensure this by not running the
+Python IDE from the project directory when importing Pystache.
+
+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.
+
+Authors
+-------
+
+::
+
+ >>> context = { 'author': 'Chris Wanstrath', 'maintainer': 'Chris Jerdonek' }
+ >>> print pystache.render("Author: {{author}}\nMaintainer: {{maintainer}}", context)
+ Author: Chris Wanstrath
+ Maintainer: Chris Jerdonek

+
+History
+=======
+
+0.5.3 (TBD)
+-----------
+
+- Added option of raising errors on missing tags/partials:
+ ``Renderer(missing_tags='strict')`` (issue #110).
+- Added a ``parse()`` function that yields a printable, pre-compiled
+ parse tree.

+- Bugfix: exceptions raised from a property are no longer swallowed
+ when getting a key from a context stack (issue #110).
+- Bugfix: lambda section values can now return non-ascii, non-unicode
+ strings (issue #118).
+- More robust handling of byte strings in Python 3.
+
+0.5.2 (2012-05-03)
+------------------
+
+- Added support for dot notation and version 1.1.2 of the spec (issue
+ #99). [rbp]
+- Missing partials now render as empty string per latest version of
+ spec (issue #115).
+- Bugfix: falsey values now coerced to strings using str().
+- Bugfix: lambda return values for sections no longer pushed onto
+ context stack (issue #113).
+- Bugfix: lists of lambdas for sections were not rendered (issue #114).
+
+0.5.1 (2012-04-24)
+------------------
+
+- Added support for Python 3.1 and 3.2.
+- Added tox support to test multiple Python versions.
+- Added test script entry point: pystache-test.
+- Added \_\_version\_\_ package attribute.
+- Test harness now supports both YAML and JSON forms of Mustache spec.
+- Test harness no longer requires nose.
+
+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.
+
