        **MacroPy** is an implementation of `Syntactic Macros
        <http://tinyurl.com/cmlls8v>`_ in the `Python Programming Language
        <http://python.org/>`_. MacroPy provides a mechanism for user-defined
        functions (macros) to perform transformations on the `abstract syntax
        tree <http://en.wikipedia.org/wiki/Abstract_syntax_tree>`_ (AST) of a
        Python program at *import time*. This is an easy way to enhance the
        semantics of a Python program in ways which are otherwise impossible,
        for example providing an extremely concise way of declaring classes.
        
        Python like you've never seen before
        ====================================
        
        MacroPy allows you to create constructs which are impossible to have
        in normal python code, such as:
        
        Tracing
        -------
        
        .. code:: python
        
            with trace:
                sum([x + 5 for x in range(3)])
        
            # sum([x + 5 for x in range(3)])
            # range(3) -> [0, 1, 2]
            # x + 5 -> 5
            # x + 5 -> 6
            # x + 5 -> 7
            # [x + 5 for x in range(3)] -> [5, 6, 7]
            # sum([x + 5 for x in range(3)]) -> 18
        
        Quick Lambdas
        -------------
        
        .. code:: python
        
            print(list(map(f[_[0]], ['omg', 'wtf', 'bbq'])))
            # ['o', 'w', 'b']
        
            print(list(reduce(f[_ + _], ['omg', 'wtf', 'bbq'])))
            # 'omgwtfbbq
        
        Case Classes
        ------------
        
        .. code:: python
        
            @case
            class Point(x, y): pass
        
            p = Point(1, 2)
        
            print str(p)    #Point(1, 2)
            print p.x       #1
            print p.y       #2
            print Point(1, 2) == Point(1, 2) # True
        
        and more! See the docs at
        `<http://macropy3.readthedocs.io/en/latest/>`_.
        
        Requirements
        ============
        
        MacroPy3 is tested to run on `CPython 3.4
        <http://en.wikipedia.org/wiki/CPython>`_ or newer and `PyPy
        <http://pypy.org/>`_ 3.5. I has no current support for `Jython
        <http://www.jython.org/>`_. MacroPy3 is also available on `PyPI
        <https://pypi.python.org/pypi/macropy3>`_.
        
        Installation
        ============
        
        Just execute a:
        
        .. code:: console
        
           $ pip install macropy3
        
        if you want to use macros that require external libraries in order to
        work, you can automatically install those dependencies by installing
        one of the ``pinq`` or ``pyxl`` extras like this:
        
        .. code:: console
        
           $ pip install macropy3[pinq,pyxl]
        
        
        then have a look at the docs at `<http://macropy3.readthedocs.io/en/latest/>`_.
        
        How to contribute
        =================
        
        We're open to contributions, so send us your
        ideas/questions/issues/pull-requests and we'll do our best to
        accommodate you! You can ask questions on the `Google Group
        <https://groups.google.com/forum/#!forum/macropy>`_  and on the

        =======
        
        MacroPy was initially created as a final project for the `MIT
        <http://web.mit.edu/>`_ class `6.945: Adventures in Advanced Symbolic
        Programming <http://groups.csail.mit.edu/mac/users/gjs/6.945/>`_,
        taught by `Gerald Jay Sussman
        <http://groups.csail.mit.edu/mac/users/gjs/>`_ and `Pavel Panchekha
        <http://pavpanchekha.com/>`_. Inspiration was taken from project such
        as `Scala Macros <http://scalamacros.org/>`_, `Karnickel
        <https://pypi.python.org/pypi/karnickel>`_ and `Pyxl
        <https://github.com/dropbox/pyxl>`_.

        Changelog
        =========
        
        1.1.0 (unreleased)
        ------------------
        
        1.1.0b2 (2018-05-12)
        --------------------
        
        - Fix readme.
        
        1.1.0b1 (2018-05-12)
        --------------------
        
        - Fix and re-enable the ``SaveExporter()`` class.
        
        - Fix some issues with pattern matching module requiring non obvious
          imports from user's side.
        
        - Fix pattern matching macro need to import ``_matching`` symbol
        
        - Add an ``OptionalMatcher`` to pattern matching macro to support
          exclusive or conditions.
        
        - Refactor documentation using sphinx.
        
        - Refactor the macro expansion core code. Now the macro expansion
          order is from inside-out. This allows to use macros inside other
          macro's body.
        
        - Added support for Python 3.4.
        
        - Added ``SELECT * FROM country`` emulation in `pinq` macro.
        
        - Update the examples.
        
        - Update tco and pyxl macros.
        
        - Prevent the import hooks from raising errors.
        
        
        1.0.4.dev2 (2017-09-08)
        -----------------------
        
        - Add MANIFEST.in;
        
        1.0.4.dev1 (2017-09-08)
        -----------------------
        
        - Updated the import machinery and macro detection to be compatible
          with Python 3.5+.
        
        - Removed support for Python 2, supporting it would require a way to
          manage differences at the ast level, but i don't use Python2 anymore.
        
        - Added support for Python 3.5+ in the form of new call arguments form
          and new ``AsyncFunctionDef``.
        
        - Basic scope analysis now available in the form of the ``@Scoped``
          decorator, to be used in conjunction with ``@Walker``.
        
        1.0.3
        -----
        
        - Error messages are now raised at run-time rather than at import
          time, with other improvements (double stack traces, catchability).
        
        - ``@enum`` macro now has much better error messages
        
        - Improved error messages for mis-use of stub functions outside their
          related macro (e.g. the ``u``, ``name``, ``ast`` stubs for the ``q``/``hq``
          macros)
        
        - Improved error messages for invalid case class signatures
        
        - Hygienic Quasiquotes now allow lexical capture of module objects
        
        1.0.2
        -----
        
        - Removed unit test from PyPI distribution
        
        1.0.1
        -----
        - Fixed a bug in ``ast_ctx_fixer``
        - ``gen_sym()`` is now ``gen_sym(name="sym")``, allowing you to override the base name
        - Implemented ``macropy.case_classes.enum`` macro
        - Implemented ``macropy.quick_lambda.lazy`` and ``macropy.quick_lambda.interned`` macros
