    002 GF3: Lisp-Like Generic Functions For Python 3
    003 =============================================
    004
    005 Overview
    006 ========
    007
    008 `gf` lets you write generic functions
    009 `generic functions <http://en.wikipedia.org/wiki/Generic_function>`_
    010 with multi-methods, that dispatch on all their arguments.
    011
    012 Simple Example
    013 --------------
    014
    015 >>> from gf import generic, method
    016 >>> add = generic()
    017 >>> type(add)
    018 <class 'function'>
    019
    020 Lets define `add` for two integers:
    021
    022 >>> @method()
    023 ... def add(n0: int, n1: int):
    024 ...     return n0 + n1
    025
    026 Lets test it:
    027
    028 >>> add(1, 2)
    029 3
    030
    031 Calling `add` with instances of other types fails:
    032
    033 >>> add("Hello ", "World")
    034 Traceback (most recent call last):
    035 ...
    036 NotImplementedError: Generic '__main__.add' has no implementation for type(s): __builtin__.str, __builtin__.str
    037
    038 Of course `add` can also by defined for two strings:
    039
    040 >>> @method()
    041 ... def add(s0: str, s1: str):
    042 ...     return s0 + s1
    043
    044 Now our hello world example works:
    045
    046 >>> add("Hello ", "World")
    047 'Hello World'
    048
    049 `add` can also be defined for a string and an integer:
    050
    051 >>> @method()
    052 ... def add(s: str, n: int):
    053 ...     return s + str(n)
    054
    055 Thus we can add a string and a number:
    056
    057 >>> add("You ", 2)
    058 'You 2'
    059
    060 Python's Special Methods
    061 ------------------------
    062
    063 `gf.Object` implements (nearly) all of the `special instance
    064 methods of a python object`_ as a generic function.
    065 The package includes a rational number implementation that makes
    066 heavy use of this feature:
    067
    068 .. code:: python
    069
    070     @method()
    071     def __add__(a: object, b: Rational):
    072         """Add an object and a rational number.
    073
    074         `a` is converted to a `Rational` and then both are added."""
    075         return Rational(a) + b
    076
    077     @method(Rational, object)
    078     def __add__(a: Rational, b: object):
    079         """Add a rational number and an object.
    080
    081         `b` is converted to a `Rational` and then both are added."""
    082         return a + Rational(b)
    083
    084 `gf.Object` also has a more Smalltalk means of overwriting
    085 `object.__str__` and `object.__repr__` using a file like object.
    086 Again the rational example is instructive about its usage.
    087
    088 .. code:: python
    089
    090     @method()
    091     def __out__(rational: Rational, writer: Writer):
    092         """Write a nice representation of the rational.
    093
    094         Denominators that equal 1 are not printed."""
    095         writer("%d", rational.numerator)
    096         if rational.denominator != 1:
    097             writer(" / %d", rational.denominator)
    098
    099     @method()
    100     def __spy__(rational: Rational, writer: Writer):
    101         """Write a debug representation of the rational."""
    102         writer("%s(", rational.__class__.__name__)
    103         if rational.numerator != 0:
    104                 writer("%r", rational.numerator)
    105                 if rational.denominator != 1:
    106                     writer(", %r", rational.denominator)
    107         writer(")")

    131 Changes
    132 -------
    133
    134 A short sketch of the changes done in each release.
    135
    136 Release 0.2.4
    137 ~~~~~~~~~~~~~
    138
    139 The following was changed in Release 0.2.4:
    140
    141   * The `push`-method accepts an identation string
    142     for identing writers.
    143   * The methods `push` and `pop` now accept
    144     arbitrary arguments in the general case.
    145   * Successfully tested the whole framework with Python 3.5.
    146
    147
    148 Release 0.2.3
    149 ~~~~~~~~~~~~~
    150
    151 The following was changed in Release 0.2.3:
    152
    153   * Fixed the long description.
    154   * Wrote some documentation about changing the implementation
    155     class of a generic function.
    156
    157
    158 Release 0.2.2
    159 ~~~~~~~~~~~~~
    160
    161 The following was changed in Release 0.2.2:
    162
    163   * Write more documentation.
    164     Especially documented the `merge` and the `isgeneric`
    165     functions.
    166   * Consistency between the long text and on PyPi and the documentation.
    167
    168
    169 Release 0.2.1
    170 ~~~~~~~~~~~~~
    171
    172 Needed to bump the version information, because the homepage
    173 in the package-information was wrong [#]_ and a new upload was needed.
    174
    175
    176 Release 0.2.0
    177 ~~~~~~~~~~~~~
    178
    179 The following was changed in Release 0.2.0:
    180
    181   * Ported the whole module to Python 3.6 and Python 3.7.
    182   * Exclusively uses `parameter annotations`_ to specify the types to dispatch on.
    183   * Added standard conforming default implementations for methods
    184     like `__add__`. All these methods now raise a proper
    185     `TypeError` instead of raising a `NotImplementedError`.
    186   * Added some means to write generic functions that dispatch types only.
    187     This is the generic function equivalent of a class-method.
    188   * Added some means to dispatch on single objects.
    189     This is the equivalent adding methods to class-instances [#]_.
    190   * The package name for PyPi is now ``gf3``.
    191
    192 .. _parameter annotations: https://docs.python.org/3/reference/compound_stmts.html#grammar-token-parameter
    193
    194
    195 Release 0.1.4
    196 ~~~~~~~~~~~~~
    197
    198 The following was fixed in Release 0.1.4:
    199
    200   * Fixed an issue with variadic methods. Sometimes definitions
    201     of variadic methods added after the method was already called
    202     where not added.
    203   * Specified and implemented a precedence rule for overlapping
    204     variadic methods of generic functions.
    205   * Improved generated documentation for variadic methods.
    206   * Fixed the markup of some notes in the documentation.
    207
    208
    209 Release 0.1.3
    210 ~~~~~~~~~~~~~
    211
    212 The following was changed in Release 0.1.3:
    213
    214   * Added variadic methods, e.g. multi-methods with a
    215     variable number of arguments.
    216   * Improved the long description text a bit
    217     and fixed bug in its markup.
    218   * Fixed invalid references in the long description.
    219
    220
    221 Release 0.1.2
    222 ~~~~~~~~~~~~~
    223
    224 The following was changed in Release 0.1.2:
    225
    226   * Added a generic functions for `gf.Object.__call__`.
    227   * Added a `gf.go.FinalizingMixin`.
    228   * `gf.generic` now also accepts a type.
    229   * Improved the exception information for ambiguous calls.
    230   * Fixed some documentation glitches.
    231
    232
    233 Release 0.1.1
    234 ~~~~~~~~~~~~~
    235
    236 This was the initial release.
    237
    238 .. [#] Silly me discovered about the shutdown of pythonhosted.org
    239        after version 0.2.0 was uploaded.
    240 .. [#] Of course this is not possible with standard python classes
    241        and their instances.

  002 GF3: Lisp-Like Generic Functions For Python 3
  003 =============================================
  004
  005 Overview
  006 ========
  007
  008 `gf` lets you write generic functions
  009 `generic functions <http://en.wikipedia.org/wiki/Generic_function>`_
  010 with multi-methods, that dispatch on all their arguments.
  011
  012 Simple Example
  013 --------------
  014
  015 >>> from gf import generic, method
  016 >>> add = generic()
  017 >>> type(add)
  018 <class 'function'>
  019
  020 Lets define `add` for two integers:
  021
  022 >>> @method()
  023 ... def add(n0: int, n1: int):
  024 ...     return n0 + n1
  025
  026 Lets test it:
  027
  028 >>> add(1, 2)
  029 3
  030
  031 Calling `add` with instances of other types fails:
  032
  033 >>> add("Hello ", "World")
  034 Traceback (most recent call last):
  035 ...
  036 NotImplementedError: Generic '__main__.add' has no implementation for type(s): __builtin__.str, __builtin__.str
  037
  038 Of course `add` can also by defined for two strings:
  039
  040 >>> @method()
  041 ... def add(s0: str, s1: str):
  042 ...     return s0 + s1
  043
  044 Now our hello world example works:
  045
  046 >>> add("Hello ", "World")
  047 'Hello World'
  048
  049 `add` can also be defined for a string and an integer:
  050
  051 >>> @method()
  052 ... def add(s: str, n: int):
  053 ...     return s + str(n)
  054
  055 Thus we can add a string and a number:
  056
  057 >>> add("You ", 2)
  058 'You 2'
  059
  060 Python's Special Methods
  061 ------------------------
  062
  063 `gf.Object` implements (nearly) all of the `special instance
  064 methods of a python object`_ as a generic function.
  065 The package includes a rational number implementation that makes
  066 heavy use of this feature:
  067
  068 .. code:: python
  069
  070     @method()
  071     def __add__(a: object, b: Rational):
  072         """Add an object and a rational number.
  073
  074         `a` is converted to a `Rational` and then both are added."""
  075         return Rational(a) + b
  076
  077     @method(Rational, object)
  078     def __add__(a: Rational, b: object):
  079         """Add a rational number and an object.
  080
  081         `b` is converted to a `Rational` and then both are added."""
  082         return a + Rational(b)
  083
  084 `gf.Object` also has a more Smalltalk means of overwriting
  085 `object.__str__` and `object.__repr__` using a file like object.
  086 Again the rational example is instructive about its usage.
  087
  088 .. code:: python
  089
  090     @method()
  091     def __out__(rational: Rational, writer: Writer):
  092         """Write a nice representation of the rational.
  093
  094         Denominators that equal 1 are not printed."""
  095         writer("%d", rational.numerator)
  096         if rational.denominator != 1:
  097             writer(" / %d", rational.denominator)
  098
  099     @method()
  100     def __spy__(rational: Rational, writer: Writer):
  101         """Write a debug representation of the rational."""
  102         writer("%s(", rational.__class__.__name__)
  103         if rational.numerator != 0:
  104                 writer("%r", rational.numerator)
  105                 if rational.denominator != 1:
  106                     writer(", %r", rational.denominator)
  107         writer(")")

  136 Release 0.2.4
  137 ~~~~~~~~~~~~~
  138
  139 The following was changed in Release 0.2.4:
  140
  141   * The `push`-method accepts an identation string
  142     for identing writers.
  143   * The methods `push` and `pop` now accept
  144     arbitrary arguments in the general case.
  145   * Successfully tested the whole framework with Python 3.5.
  146
  147
  148 Release 0.2.3
  149 ~~~~~~~~~~~~~
  150
  151 The following was changed in Release 0.2.3:
  152
  153   * Fixed the long description.
  154   * Wrote some documentation about changing the implementation
  155     class of a generic function.
  156
  157
  158 Release 0.2.2
  159 ~~~~~~~~~~~~~
  160
  161 The following was changed in Release 0.2.2:
  162
  163   * Write more documentation.
  164     Especially documented the `merge` and the `isgeneric`
  165     functions.
  166   * Consistency between the long text and on PyPi and the documentation.
  167
  168
  169 Release 0.2.1
  170 ~~~~~~~~~~~~~
  171
  172 Needed to bump the version information, because the homepage
  173 in the package-information was wrong [#]_ and a new upload was needed.
  174
  175
  176 Release 0.2.0
  177 ~~~~~~~~~~~~~
  178
  179 The following was changed in Release 0.2.0:
  180
  181   * Ported the whole module to Python 3.6 and Python 3.7.
  182   * Exclusively uses `parameter annotations`_ to specify the types to dispatch on.
  183   * Added standard conforming default implementations for methods
  184     like `__add__`. All these methods now raise a proper
  185     `TypeError` instead of raising a `NotImplementedError`.
  186   * Added some means to write generic functions that dispatch types only.
  187     This is the generic function equivalent of a class-method.
  188   * Added some means to dispatch on single objects.
  189     This is the equivalent adding methods to class-instances [#]_.
  190   * The package name for PyPi is now ``gf3``.
  191
  192 .. _parameter annotations: https://docs.python.org/3/reference/compound_stmts.html#grammar-token-parameter
  193
  194
  195 Release 0.1.4
  196 ~~~~~~~~~~~~~
  197
  198 The following was fixed in Release 0.1.4:
  199
  200   * Fixed an issue with variadic methods. Sometimes definitions
  201     of variadic methods added after the method was already called
  202     where not added.
  203   * Specified and implemented a precedence rule for overlapping
  204     variadic methods of generic functions.
  205   * Improved generated documentation for variadic methods.
  206   * Fixed the markup of some notes in the documentation.
  207
  208
  209 Release 0.1.3
  210 ~~~~~~~~~~~~~
  211
  212 The following was changed in Release 0.1.3:
  213
  214   * Added variadic methods, e.g. multi-methods with a
  215     variable number of arguments.
  216   * Improved the long description text a bit
  217     and fixed bug in its markup.
  218   * Fixed invalid references in the long description.
  219
  220
  221 Release 0.1.2
  222 ~~~~~~~~~~~~~
  223
  224 The following was changed in Release 0.1.2:
  225
  226   * Added a generic functions for `gf.Object.__call__`.
  227   * Added a `gf.go.FinalizingMixin`.
  228   * `gf.generic` now also accepts a type.
  229   * Improved the exception information for ambiguous calls.
  230   * Fixed some documentation glitches.
  231
  232
  233 Release 0.1.1
  234 ~~~~~~~~~~~~~
  235
  236 This was the initial release.
  237
  238 .. [#] Silly me discovered about the shutdown of pythonhosted.org
  239        after version 0.2.0 was uploaded.
  240 .. [#] Of course this is not possible with standard python classes
  241        and their instances.
