# class. Further, we need to know when it is likely an instance
# method, as opposed to a class or static method. This can
# become problematic though as there isn't strictly a fool proof
# method of knowing.
#
# The situations we could encounter when wrapping a method are:
#
# 1. The wrapper is being applied as part of a decorator which
# is a part of the class definition. In this case what we are
# given is the raw unbound function, classmethod or staticmethod
# wrapper objects.
#
# The problem here is that we will not know we are being applied
# in the context of the class being set up. This becomes
# important later for the case of an instance method, because in
# that case we just see it as a raw function and can't
# distinguish it from wrapping a normal function outside of
# a class context.
#
# 2. The wrapper is being applied when performing monkey
# patching of the class type afterwards and the method to be
# wrapped was retrieved direct from the __dict__ of the class
# type. This is effectively the same as (1) above.
#
# 3. The wrapper is being applied when performing monkey
# patching of the class type afterwards and the method to be
# wrapped was retrieved from the class type. In this case
# binding will have been performed where the instance against
# which the method is bound will be None at that point.
#
# This case is a problem because we can no longer tell if the
# method was a static method, plus if using Python3, we cannot
# tell if it was an instance method as the concept of an
# unnbound method no longer exists.
#
# 4. The wrapper is being applied when performing monkey
# patching of an instance of a class. In this case binding will
# have been perfomed where the instance was not None.
#
# This case is a problem because we can no longer tell if the
# method was a static method.
#
# Overall, the best we can do is look at the original type of the
# object which was wrapped prior to any binding being done and
# see if it is an instance of classmethod or staticmethod. In
# the case where other decorators are between us and them, if
# they do not propagate the __class__ attribute so that the
# isinstance() checks works, then likely this will do the wrong
# thing where classmethod and staticmethod are used.
#
# Since it is likely to be very rare that anyone even puts
# decorators around classmethod and staticmethod, likelihood of
# that being an issue is very small, so we accept it and suggest
# that those other decorators be fixed. It is also only an issue
# if a decorator wants to actually do things with the arguments.
#
# As to not being able to identify static methods properly, we
# just hope that that isn't something people are going to want
# to wrap, or if they do suggest they do it the correct way by
# ensuring that it is decorated in the class definition itself,
# or patch it in the __dict__ of the class type.
#
# So to get the best outcome we can, whenever we aren't sure what
# it is, we label it as a 'function'. If it was already bound and
# that is rebound later, we assume that it will be an instance
# method and try an cope with the possibility that the 'self'
# argument it being passed as an explicit argument and shuffle
# the arguments around to extract 'self' for use as the instance.

This is an implementation of Vaughan R. Pratt's
"Top Down Operator Precedence" parser.
(http://dl.acm.org/citation.cfm?doid=512927.512931).
These are some additional resources that help explain the
general idea behind a Pratt parser:
* http://effbot.org/zone/simple-top-down-parsing.htm
* http://javascript.crockford.com/tdop/tdop.html
A few notes on the implementation.
* All the nud/led tokens are on the Parser class itself, and are dispatched
using getattr(). This keeps all the parsing logic contained to a single
class.
* We use two passes through the data. One to create a list of token,
then one pass through the tokens to create the AST. While the lexer actually
yields tokens, we convert it to a list so we can easily implement two tokens
of lookahead. A previous implementation used a fixed circular buffer, but it
was significantly slower. Also, the average jmespath expression typically
does not have a large amount of token so this is not an issue. And
interestingly enough, creating a token list first is actually faster than
consuming from the token iterator one token at a time.

Create a new attribute on a class.
.. warning::
Does *not* do anything unless the class is also decorated with
`attr.s`!
:param default: A value that is used if an ``attrs``-generated ``__init__``
is used and no value is passed while instantiating or the attribute is
excluded using ``init=False``.
If the value is an instance of `Factory`, its callable will be
used to construct a new value (useful for mutable data types like lists
or dicts).
If a default is not set (or set manually to `attr.NOTHING`), a value
*must* be supplied when instantiating; otherwise a `TypeError`
will be raised.
The default can also be set using decorator notation as shown below.
:type default: Any value
:param callable factory: Syntactic sugar for
``default=attr.Factory(factory)``.
:param validator: `callable` that is called by ``attrs``-generated
``__init__`` methods after the instance has been initialized. They
receive the initialized instance, the `Attribute`, and the
passed value.
The return value is *not* inspected so the validator has to throw an
exception itself.
If a `list` is passed, its items are treated as validators and must
all pass.
Validators can be globally disabled and re-enabled using
`get_run_validators`.
The validator can also be set using decorator notation as shown below.
:type validator: `callable` or a `list` of `callable`\\ s.
:param repr: Include this attribute in the generated ``__repr__``
method. If ``True``, include the attribute; if ``False``, omit it. By
default, the built-in ``repr()`` function is used. To override how the
attribute value is formatted, pass a ``callable`` that takes a single
value and returns a string. Note that the resulting string is used
as-is, i.e. it will be used directly *instead* of calling ``repr()``
(the default).
:type repr: a `bool` or a `callable` to use a custom function.
:param bool eq: If ``True`` (default), include this attribute in the
generated ``__eq__`` and ``__ne__`` methods that check two instances
for equality.
:param bool order: If ``True`` (default), include this attributes in the
generated ``__lt__``, ``__le__``, ``__gt__`` and ``__ge__`` methods.
:param bool cmp: Setting to ``True`` is equivalent to setting ``eq=True,
order=True``. Deprecated in favor of *eq* and *order*.
:param Optional[bool] hash: Include this attribute in the generated
``__hash__`` method. If ``None`` (default), mirror *eq*'s value. This
is the correct behavior according the Python spec. Setting this value
to anything else than ``None`` is *discouraged*.
:param bool init: Include this attribute in the generated ``__init__``
method. It is possible to set this to ``False`` and set a default
value. In that case this attributed is unconditionally initialized
with the specified default value or factory.
:param callable converter: `callable` that is called by
``attrs``-generated ``__init__`` methods to convert attribute's value
to the desired format. It is given the passed-in value, and the
returned value will be used as the new value of the attribute. The
value is converted before being passed to the validator, if any.
:param metadata: An arbitrary mapping, to be used by third-party
components. See `extending_metadata`.
:param type: The type of the attribute. In Python 3.6 or greater, the
preferred method to specify the type is using a variable annotation
(see `PEP 526 <https://www.python.org/dev/peps/pep-0526/>`_).
This argument is provided for backward compatibility.
Regardless of the approach used, the type will be stored on
``Attribute.type``.
Please note that ``attrs`` doesn't do anything with this metadata by
itself. You can use it as part of your own code or for
`static type checking <types>`.
:param kw_only: Make this attribute keyword-only (Python 3+)
in the generated ``__init__`` (if ``init`` is ``False``, this
parameter is ignored).
:param on_setattr: Allows to overwrite the *on_setattr* setting from
`attr.s`. If left `None`, the *on_setattr* value from `attr.s` is used.
Set to `attr.setters.NO_OP` to run **no** `setattr` hooks for this
attribute -- regardless of the setting in `attr.s`.
:type on_setattr: `callable`, or a list of callables, or `None`, or
`attr.setters.NO_OP`

r"""
A class decorator that adds `dunder
<https://wiki.python.org/moin/DunderAlias>`_\ -methods according to the
specified attributes using `attr.ib` or the *these* argument.
:param these: A dictionary of name to `attr.ib` mappings. This is
useful to avoid the definition of your attributes within the class body
because you can't (e.g. if you want to add ``__repr__`` methods to
Django models) or don't want to.
If *these* is not ``None``, ``attrs`` will *not* search the class body
for attributes and will *not* remove any attributes from it.
If *these* is an ordered dict (`dict` on Python 3.6+,
`collections.OrderedDict` otherwise), the order is deduced from
the order of the attributes inside *these*. Otherwise the order
of the definition of the attributes is used.
:type these: `dict` of `str` to `attr.ib`
:param str repr_ns: When using nested classes, there's no way in Python 2
to automatically detect that. Therefore it's possible to set the
namespace explicitly for a more meaningful ``repr`` output.
:param bool auto_detect: Instead of setting the *init*, *repr*, *eq*,
*order*, and *hash* arguments explicitly, assume they are set to
``True`` **unless any** of the involved methods for one of the
arguments is implemented in the *current* class (i.e. it is *not*
inherited from some base class).
So for example by implementing ``__eq__`` on a class yourself,
``attrs`` will deduce ``eq=False`` and won't create *neither*
``__eq__`` *nor* ``__ne__`` (but Python classes come with a sensible
``__ne__`` by default, so it *should* be enough to only implement
``__eq__`` in most cases).
.. warning::
If you prevent ``attrs`` from creating the ordering methods for you
(``order=False``, e.g. by implementing ``__le__``), it becomes
*your* responsibility to make sure its ordering is sound. The best
way is to use the `functools.total_ordering` decorator.
Passing ``True`` or ``False`` to *init*, *repr*, *eq*, *order*,
*cmp*, or *hash* overrides whatever *auto_detect* would determine.
*auto_detect* requires Python 3. Setting it ``True`` on Python 2 raises
a `PythonTooOldError`.
:param bool repr: Create a ``__repr__`` method with a human readable
representation of ``attrs`` attributes..
:param bool str: Create a ``__str__`` method that is identical to
``__repr__``. This is usually not necessary except for
`Exception`\ s.
:param Optional[bool] eq: If ``True`` or ``None`` (default), add ``__eq__``
and ``__ne__`` methods that check two instances for equality.
They compare the instances as if they were tuples of their ``attrs``
attributes if and only if the types of both classes are *identical*!
:param Optional[bool] order: If ``True``, add ``__lt__``, ``__le__``,
``__gt__``, and ``__ge__`` methods that behave like *eq* above and
allow instances to be ordered. If ``None`` (default) mirror value of
*eq*.
:param Optional[bool] cmp: Setting to ``True`` is equivalent to setting
``eq=True, order=True``. Deprecated in favor of *eq* and *order*, has
precedence over them for backward-compatibility though. Must not be
mixed with *eq* or *order*.
:param Optional[bool] hash: If ``None`` (default), the ``__hash__`` method
is generated according how *eq* and *frozen* are set.
1. If *both* are True, ``attrs`` will generate a ``__hash__`` for you.
2. If *eq* is True and *frozen* is False, ``__hash__`` will be set to
None, marking it unhashable (which it is).
3. If *eq* is False, ``__hash__`` will be left untouched meaning the
``__hash__`` method of the base class will be used (if base class is
``object``, this means it will fall back to id-based hashing.).
Although not recommended, you can decide for yourself and force
``attrs`` to create one (e.g. if the class is immutable even though you
didn't freeze it programmatically) by passing ``True`` or not. Both of
these cases are rather special and should be used carefully.
See our documentation on `hashing`, Python's documentation on
`object.__hash__`, and the `GitHub issue that led to the default \
behavior <https://github.com/python-attrs/attrs/issues/136>`_ for more
details.
:param bool init: Create a ``__init__`` method that initializes the
``attrs`` attributes. Leading underscores are stripped for the
argument name. If a ``__attrs_post_init__`` method exists on the
class, it will be called after the class is fully initialized.
:param bool slots: Create a `slotted class <slotted classes>` that's more
memory-efficient.
:param bool frozen: Make instances immutable after initialization. If
someone attempts to modify a frozen instance,
`attr.exceptions.FrozenInstanceError` is raised.
Please note:
1. This is achieved by installing a custom ``__setattr__`` method
on your class, so you can't implement your own.
2. True immutability is impossible in Python.
3. This *does* have a minor a runtime performance `impact
<how-frozen>` when initializing new instances. In other words:
``__init__`` is slightly slower with ``frozen=True``.
4. If a class is frozen, you cannot modify ``self`` in
``__attrs_post_init__`` or a self-written ``__init__``. You can
circumvent that limitation by using
``object.__setattr__(self, "attribute_name", value)``.
5. Subclasses of a frozen class are frozen too.
:param bool weakref_slot: Make instances weak-referenceable. This has no
effect unless ``slots`` is also enabled.
:param bool auto_attribs: If ``True``, collect `PEP 526`_-annotated
attributes (Python 3.6 and later only) from the class body.
In this case, you **must** annotate every field. If ``attrs``
encounters a field that is set to an `attr.ib` but lacks a type
annotation, an `attr.exceptions.UnannotatedAttributeError` is
raised. Use ``field_name: typing.Any = attr.ib(...)`` if you don't
want to set a type.
If you assign a value to those attributes (e.g. ``x: int = 42``), that
value becomes the default value like if it were passed using
``attr.ib(default=42)``. Passing an instance of `Factory` also
works as expected.
Attributes annotated as `typing.ClassVar`, and attributes that are
neither annotated nor set to an `attr.ib` are **ignored**.
.. _`PEP 526`: https://www.python.org/dev/peps/pep-0526/
:param bool kw_only: Make all attributes keyword-only (Python 3+)
in the generated ``__init__`` (if ``init`` is ``False``, this
parameter is ignored).
:param bool cache_hash: Ensure that the object's hash code is computed
only once and stored on the object. If this is set to ``True``,
hashing must be either explicitly or implicitly enabled for this
class. If the hash code is cached, avoid any reassignments of
fields involved in hash code computation or mutations of the objects
those fields point to after object creation. If such changes occur,
the behavior of the object's hash code is undefined.
:param bool auto_exc: If the class subclasses `BaseException`
(which implicitly includes any subclass of any exception), the
following happens to behave like a well-behaved Python exceptions
class:
- the values for *eq*, *order*, and *hash* are ignored and the
instances compare and hash by the instance's ids (N.B. ``attrs`` will
*not* remove existing implementations of ``__hash__`` or the equality
methods. It just won't add own ones.),
- all attributes that are either passed into ``__init__`` or have a
default value are additionally available as a tuple in the ``args``
attribute,
- the value of *str* is ignored leaving ``__str__`` to base classes.
:param bool collect_by_mro: Setting this to `True` fixes the way ``attrs``
collects attributes from base classes. The default behavior is
incorrect in certain cases of multiple inheritance. It should be on by
default but is kept off for backward-compatability.
See issue `#428 <https://github.com/python-attrs/attrs/issues/428>`_ for
more details.
:param Optional[bool] getstate_setstate:
.. note::
This is usually only interesting for slotted classes and you should
probably just set *auto_detect* to `True`.
If `True`, ``__getstate__`` and
``__setstate__`` are generated and attached to the class. This is
necessary for slotted classes to be pickleable. If left `None`, it's
`True` by default for slotted classes and ``False`` for dict classes.
If *auto_detect* is `True`, and *getstate_setstate* is left `None`,
and **either** ``__getstate__`` or ``__setstate__`` is detected directly
on the class (i.e. not inherited), it is set to `False` (this is usually
what you want).
:param on_setattr: A callable that is run whenever the user attempts to set
an attribute (either by assignment like ``i.x = 42`` or by using
`setattr` like ``setattr(i, "x", 42)``). It receives the same argument
as validators: the instance, the attribute that is being modified, and
the new value.
If no exception is raised, the attribute is set to the return value of

omniverse-code/kit/exts/omni.kit.pip_archive/pip_prebundle/setuptools/build_meta.py | """A PEP 517 interface to setuptools
Previously, when a user or a command line tool (let's call it a "frontend")
needed to make a request of setuptools to take a certain action, for
example, generating a list of installation requirements, the frontend would
would call "setup.py egg_info" or "setup.py bdist_wheel" on the command line.
PEP 517 defines a different method of interfacing with setuptools. Rather
than calling "setup.py" directly, the frontend should:
1. Set the current directory to the directory with a setup.py file
2. Import this module into a safe python interpreter (one in which
setuptools can potentially set global variables or crash hard).
3. Call one of the functions defined in PEP 517.
What each function does is defined in PEP 517. However, here is a "casual"
definition of the functions (this definition should not be relied on for
bug reports or API stability):
- `build_wheel`: build a wheel in the folder and return the basename
- `get_requires_for_build_wheel`: get the `setup_requires` to build
- `prepare_metadata_for_build_wheel`: get the `install_requires`
- `build_sdist`: build an sdist in the folder and return the basename
- `get_requires_for_build_sdist`: get the `setup_requires` to build
Again, this is not a formal definition! Just a "taste" of the module.

``importlib.machinery.EXTENSION_SUFFIXES``).
In the case ``.pyx`` files are passed as ``sources and`` ``Cython`` is **not**
installed in the build environment, ``setuptools`` may also try to look for the
equivalent ``.cpp`` or ``.c`` files.
:arg str name:
the full name of the extension, including any packages -- ie.
*not* a filename or pathname, but Python dotted name
:arg list[str] sources:
list of source filenames, relative to the distribution root
(where the setup script lives), in Unix form (slash-separated)
for portability. Source files may be C, C++, SWIG (.i),
platform-specific resource files, or whatever else is recognized
by the "build_ext" command as source for a Python extension.
:keyword list[str] include_dirs:
list of directories to search for C/C++ header files (in Unix
form for portability)
:keyword list[tuple[str, str|None]] define_macros:
list of macros to define; each macro is defined using a 2-tuple:
the first item corresponding to the name of the macro and the second
item either a string with its value or None to
define it without a particular value (equivalent of "#define

list of directories to search for C/C++ libraries at link time

list of library names (not filenames or paths) to link against
:keyword list[str] runtime_library_dirs:
list of directories to search for C/C++ libraries at run time
(for shared extensions, this is when the extension is loaded).
Setting this will cause an exception during build on Windows
platforms.
:keyword list[str] extra_objects:
list of extra files to link with (eg. object files not implied
by 'sources', static library that must be explicitly specified,
binary resource files, etc.)
:keyword list[str] extra_compile_args:
any extra platform- and compiler-specific information to use
when compiling the source files in 'sources'. For platforms and
compilers where "command line" makes sense, this is typically a
list of command-line arguments, but for other platforms it could
be anything.
:keyword list[str] extra_link_args:
any extra platform- and compiler-specific information to use
when linking object files together to create the extension (or
to create a new static Python interpreter). Similar
interpretation as for 'extra_compile_args'.
:keyword list[str] export_symbols:
list of symbols to be exported from a shared extension. Not
used on all platforms, and not generally necessary for Python
extensions, which typically export exactly one symbol: "init" +
extension_name.
:keyword list[str] swig_opts:
any extra options to pass to SWIG if a source file has the .i
extension.
:keyword list[str] depends:
list of files that the extension depends on
:keyword str language:
extension language (i.e. "c", "c++", "objc"). Will be detected
from the source extensions if not provided.

specifies that a build failure in the extension should not abort the

"""
Setuptools internal actions are organized using a *command design pattern*.
This means that each action (or group of closely related actions) executed during
the build should be implemented as a ``Command`` subclass.
These commands are abstractions and do not necessarily correspond to a command that
can (or should) be executed via a terminal, in a CLI fashion (although historically
they would).
When creating a new command from scratch, custom defined classes **SHOULD** inherit
from ``setuptools.Command`` and implement a few mandatory methods.
Between these mandatory methods, are listed:
.. method:: initialize_options(self)
Set or (reset) all options/attributes/caches used by the command
to their default values. Note that these values may be overwritten during
the build.
.. method:: finalize_options(self)
Set final values for all options/attributes used by the command.
Most of the time, each option/attribute/cache should only be set if it does not
have any value yet (e.g. ``if self.attr is None: self.attr = val``).
.. method:: run(self)
Execute the actions intended by the command.
(Side effects **SHOULD** only take place when ``run`` is executed,
for example, creating new files or writing to the terminal output).
A useful analogy for command classes is to think of them as subroutines with local
variables called "options". The options are "declared" in ``initialize_options()``
and "defined" (given their final values, aka "finalized") in ``finalize_options()``,
both of which must be defined by every command class. The "body" of the subroutine,
(where it does all the work) is the ``run()`` method.
Between ``initialize_options()`` and ``finalize_options()``, ``setuptools`` may set
the values for options/attributes based on user's input (or circumstance),
which means that the implementation should be careful to not overwrite values in
``finalize_options`` unless necessary.
Please note that other commands (or other parts of setuptools) may also overwrite
the values of the command's options/attributes multiple times during the build
process.
Therefore it is important to consistently implement ``initialize_options()`` and
``finalize_options()``. For example, all derived attributes (or attributes that
depend on the value of other attributes) **SHOULD** be recomputed in
``finalize_options``.
When overwriting existing commands, custom defined classes **MUST** abide by the
same APIs implemented by the original class. They also **SHOULD** inherit from the
original class.

about which packages to include or to make the discovery parameters more specific.

leaving auxiliary code in the repository top-level, such as maintenance-related

"""Distribution with support for tests and package data
This is an enhanced version of 'distutils.dist.Distribution' that
effectively adds the following new optional keyword arguments to 'setup()':
'install_requires' -- a string or sequence of strings specifying project
versions that the distribution requires when installed, in the format
used by 'pkg_resources.require()'. They will be installed
automatically when the package is installed. If you wish to use
packages that are not available in PyPI, or want to give your users an
alternate download location, you can add a 'find_links' option to the
'[easy_install]' section of your project's 'setup.cfg' file, and then
setuptools will scan the listed web pages for links that satisfy the
requirements.
'extras_require' -- a dictionary mapping names of optional "extras" to the
additional requirement(s) that using those extras incurs. For example,
this::
extras_require = dict(reST = ["docutils>=0.3", "reSTedit"])
indicates that the distribution can optionally provide an extra
capability called "reST", but it can only be used if docutils and
reSTedit are installed. If the user installs your package using
EasyInstall and requests one of your extras, the corresponding
additional requirements will be installed if needed.
'test_suite' -- the name of a test suite to run for the 'test' command.
If the user runs 'python setup.py test', the package will be installed,
and the named test suite will be run. The format is the same as
would be used on a 'unittest.py' command line. That is, it is the
dotted name of an object to import and call to generate a test suite.
'package_data' -- a dictionary mapping package names to lists of filenames
or globs to use to find data files contained in the named packages.
If the dictionary has filenames or globs listed under '""' (the empty
string), those names will be searched for in every package, in addition
to any names for the specific package. Data files found using these
names/globs will be installed along with the package, in the same
location as the package. Note that globs are allowed to reference
the contents of non-package subdirectories, as long as you use '/' as
a path separator. (Globs are automatically converted to
platform-specific paths at runtime.)
In addition to these new keywords, this class also has several new methods
for manipulating the distribution's contents. For example, the 'include()'
and 'exclude()' methods can be thought of as in-place add and subtract
commands that add or remove packages, modules, extensions, and so on from
the distribution.

packages, modules, and extensions are also excluded.
Currently, this method only supports exclusion from attributes that are
lists or tuples. If you need to add support for excluding from other
attributes in this or a subclass, you can add an '_exclude_X' method,
where 'X' is the name of the attribute. The method will be called with
the value passed to 'exclude()'. So, 'dist.exclude(foo={"bar":"baz"})'
will try to call 'dist._exclude_foo({"bar":"baz"})', which can then
handle whatever special exclusion logic is needed.

class RangeMap(dict):
"""
A dictionary-like object that uses the keys as bounds for a range.
Inclusion of the value for that range is determined by the
key_match_comparator, which defaults to less-than-or-equal.
A value is returned for a key if it is the first key that matches in
the sorted list of keys.
One may supply keyword parameters to be passed to the sort function used
to sort keys (i.e. key, reverse) as sort_params.
Let's create a map that maps 1-3 -> 'a', 4-6 -> 'b'
>>> r = RangeMap({3: 'a', 6: 'b'}) # boy, that was easy
>>> r[1], r[2], r[3], r[4], r[5], r[6]
('a', 'a', 'a', 'b', 'b', 'b')
Even float values should work so long as the comparison operator
supports it.
>>> r[4.5]
'b'
But you'll notice that the way rangemap is defined, it must be open-ended
on one side.
>>> r[0]
'a'
>>> r[-1]
'a'
One can close the open-end of the RangeMap by using undefined_value
>>> r = RangeMap({0: RangeMap.undefined_value, 3: 'a', 6: 'b'})
>>> r[0]
Traceback (most recent call last):
...
KeyError: 0
One can get the first or last elements in the range by using RangeMap.Item
>>> last_item = RangeMap.Item(-1)
>>> r[last_item]
'b'
.last_item is a shortcut for Item(-1)
>>> r[RangeMap.last_item]
'b'
Sometimes it's useful to find the bounds for a RangeMap
>>> r.bounds()
(0, 6)
RangeMap supports .get(key, default)
>>> r.get(0, 'not found')
'not found'
>>> r.get(7, 'not found')
'not found'
One often wishes to define the ranges by their left-most values,
which requires use of sort params and a key_match_comparator.
>>> r = RangeMap({1: 'a', 4: 'b'},
... sort_params=dict(reverse=True),
... key_match_comparator=operator.ge)
>>> r[1], r[2], r[3], r[4], r[5], r[6]
('a', 'a', 'a', 'b', 'b', 'b')
That wasn't nearly as easy as before, so an alternate constructor
is provided:
>>> r = RangeMap.left({1: 'a', 4: 'b', 7: RangeMap.undefined_value})
>>> r[1], r[2], r[3], r[4], r[5], r[6]
('a', 'a', 'a', 'b', 'b', 'b')

class Extension:
"""Just a collection of attributes that describes an extension
module and everything needed to build it (hopefully in a portable
way, but there are hooks that let you be as unportable as you need).
Instance attributes:
name : string
the full name of the extension, including any packages -- ie.
*not* a filename or pathname, but Python dotted name
sources : [string]
list of source filenames, relative to the distribution root
(where the setup script lives), in Unix form (slash-separated)
for portability. Source files may be C, C++, SWIG (.i),
platform-specific resource files, or whatever else is recognized
by the "build_ext" command as source for a Python extension.
include_dirs : [string]
list of directories to search for C/C++ header files (in Unix
form for portability)
define_macros : [(name : string, value : string|None)]
list of macros to define; each macro is defined using a 2-tuple,
where 'value' is either the string to define it to or None to
define it without a particular value (equivalent of "#define
FOO" in source or -DFOO on Unix C compiler command line)
undef_macros : [string]
list of macros to undefine explicitly
library_dirs : [string]
list of directories to search for C/C++ libraries at link time
libraries : [string]
list of library names (not filenames or paths) to link against
runtime_library_dirs : [string]
list of directories to search for C/C++ libraries at run time
(for shared extensions, this is when the extension is loaded)
extra_objects : [string]
list of extra files to link with (eg. object files not implied
by 'sources', static library that must be explicitly specified,
binary resource files, etc.)
extra_compile_args : [string]
any extra platform- and compiler-specific information to use
when compiling the source files in 'sources'. For platforms and
compilers where "command line" makes sense, this is typically a
list of command-line arguments, but for other platforms it could
be anything.
extra_link_args : [string]
any extra platform- and compiler-specific information to use
when linking object files together to create the extension (or
to create a new static Python interpreter). Similar
interpretation as for 'extra_compile_args'.
export_symbols : [string]
list of symbols to be exported from a shared extension. Not
used on all platforms, and not generally necessary for Python
extensions, which typically export exactly one symbol: "init" +
extension_name.
swig_opts : [string]
any extra options to pass to SWIG if a source file has the .i
extension.
depends : [string]
list of files that the extension depends on
language : string
extension language (i.e. "c", "c++", "objc"). Will be detected
from the source extensions if not provided.
optional : boolean
specifies that a build failure in the extension should not abort the
build process, but simply not install the failing extension.

The Distribution instance might be an instance of a class supplied via

All other arguments to 'setup' (except for 'cmdclass') are used to set

will be turned into a command class, which is in turn instantiated; any
class found in 'cmdclass' is used in place of the default, which is
(for command 'foo_bar') class 'foo_bar' in module

'distutils.fancy_getopt'. Any command-line options between the current

When the entire command-line has been successfully parsed, calls the
