+    """This function creates an iterable context manager that can be used
+    to iterate over something while showing a progress bar.  It will
+    either iterate over the `iterable` or `length` items (that are counted
+    up).  While iteration happens, this function will print a rendered
+    progress bar to the given `file` (defaults to stdout) and will attempt
+    to calculate remaining time and more.  By default, this progress bar
+    will not be rendered if the file is not a terminal.
+
+    The context manager creates the progress bar.  When the context
+    manager is entered the progress bar is already created.  With every
+    iteration over the progress bar, the iterable passed to the bar is
+    advanced and the bar is updated.  When the context manager exits,
+    a newline is printed and the progress bar is finalized on screen.
+
+    Note: The progress bar is currently designed for use cases where the
+    total progress can be expected to take at least several seconds.
+    Because of this, the ProgressBar class object won't display
+    progress that is considered too fast, and progress where the time
+    between steps is less than a second.
+
+    No printing must happen or the progress bar will be unintentionally
+    destroyed.
+
+    Example usage::
+
+        with progressbar(items) as bar:
+            for item in bar:
+                do_something_with(item)
+
+    Alternatively, if no iterable is specified, one can manually update the
+    progress bar through the `update()` method instead of directly
+    iterating over the progress bar.  The update method accepts the number
+    of steps to increment the bar with::
+
+        with progressbar(length=chunks.total_bytes) as bar:
+            for chunk in chunks:
+                process_chunk(chunk)
+                bar.update(chunks.bytes)
+
+    The ``update()`` method also takes an optional value specifying the
+    ``current_item`` at the new position. This is useful when used
+    together with ``item_show_func`` to customize the output for each
+    manual step::
+
+        with click.progressbar(
+            length=total_size,
+            label='Unzipping archive',
+            item_show_func=lambda a: a.filename
+        ) as bar:
+            for archive in zip_file:
+                archive.extract()
+                bar.update(archive.size, archive)
+
+    :param iterable: an iterable to iterate over.  If not provided the length
+                     is required.
+    :param length: the number of items to iterate over.  By default the
+                   progressbar will attempt to ask the iterator about its
+                   length, which might or might not work.  If an iterable is
+                   also provided this parameter can be used to override the
+                   length.  If an iterable is not provided the progress bar
+                   will iterate over a range of that length.
+    :param label: the label to show next to the progress bar.
+    :param show_eta: enables or disables the estimated time display.  This is
+                     automatically disabled if the length cannot be
+                     determined.
+    :param show_percent: enables or disables the percentage display.  The
+                         default is `True` if the iterable has a length or
+                         `False` if not.
+    :param show_pos: enables or disables the absolute position display.  The
+                     default is `False`.
+    :param item_show_func: A function called with the current item which
+        can return a string to show next to the progress bar. If the
+        function returns ``None`` nothing is shown. The current item can
+        be ``None``, such as when entering and exiting the bar.

+                         The parameters in it are ``label`` for the label,

+                  default is autodetection.  This is only needed if ANSI
+                  codes are included anywhere in the progress bar output
+                  which is not the case by default.

+Installation
+------------
+
+Tested on CPython 2.7, 3.7, 3.8, 3.9 and 3.10 and Pypy 2.7 and 3.8.
+
+No requirements other than the standard library.
+
+.. code-block:: bash
+
+    pip install colorama
+    # or
+    conda install -c anaconda colorama
+
+Description
+-----------
+
+ANSI escape character sequences have long been used to produce colored terminal
+text and cursor positioning on Unix and Macs. Colorama makes this work on
+Windows, too, by wrapping ``stdout``, stripping ANSI sequences it finds (which
+would appear as gobbledygook in the output), and converting them into the
+appropriate win32 calls to modify the state of the terminal. On other platforms,
+Colorama does nothing.
+
+This has the upshot of providing a simple cross-platform API for printing
+colored terminal text from Python, and has the happy side-effect that existing
+applications or libraries which use ANSI sequences to produce colored output on
+Linux or Macs can now also work on Windows, simply by calling
+``colorama.just_fix_windows_console()`` (since v0.4.6) or ``colorama.init()``
+(all versions, but may have other side-effects – see below).
+
+An alternative approach is to install ``ansi.sys`` on Windows machines, which
+provides the same behaviour for all applications running in terminals. Colorama
+is intended for situations where that isn't easy (e.g., maybe your app doesn't
+have an installer.)
+
+Demo scripts in the source code repository print some colored text using
+ANSI sequences. Compare their output under Gnome-terminal's built in ANSI
+handling, versus on Windows Command-Prompt using Colorama:

+    :height: 325
+    :alt: Same ANSI sequences on Windows, using Colorama.
+
+These screenshots show that, on Windows, Colorama does not support ANSI 'dim
+text'; it looks the same as 'normal text'.
+
+Usage
+-----
+
+Initialisation
+..............
+
+If the only thing you want from Colorama is to get ANSI escapes to work on
+Windows, then run:
+
+.. code-block:: python
+
+    from colorama import just_fix_windows_console
+    just_fix_windows_console()
+
+If you're on a recent version of Windows 10 or better, and your stdout/stderr
+are pointing to a Windows console, then this will flip the magic configuration
+switch to enable Windows' built-in ANSI support.
+
+If you're on an older version of Windows, and your stdout/stderr are pointing to
+a Windows console, then this will wrap ``sys.stdout`` and/or ``sys.stderr`` in a
+magic file object that intercepts ANSI escape sequences and issues the
+appropriate Win32 calls to emulate them.
+
+In all other circumstances, it does nothing whatsoever. Basically the idea is
+that this makes Windows act like Unix with respect to ANSI escape handling.
+
+It's safe to call this function multiple times. It's safe to call this function
+on non-Windows platforms, but it won't do anything. It's safe to call this
+function when one or both of your stdout/stderr are redirected to a file – it
+won't do anything to those streams.
+
+Alternatively, you can use the older interface with more features (but also more
+potential footguns):
+
+.. code-block:: python
+
+    from colorama import init
+    init()
+
+This does the same thing as ``just_fix_windows_console``, except for the
+following differences:
+
+- It's not safe to call ``init`` multiple times; you can end up with multiple
+  layers of wrapping and broken ANSI support.
+
+- Colorama will apply a heuristic to guess whether stdout/stderr support ANSI,
+  and if it thinks they don't, then it will wrap ``sys.stdout`` and
+  ``sys.stderr`` in a magic file object that strips out ANSI escape sequences
+  before printing them. This happens on all platforms, and can be convenient if
+  you want to write your code to emit ANSI escape sequences unconditionally, and
+  let Colorama decide whether they should actually be output. But note that
+  Colorama's heuristic is not particularly clever.
+
+- ``init`` also accepts explicit keyword args to enable/disable various
+  functionality – see below.
+
+To stop using Colorama before your program exits, simply call ``deinit()``.
+This will restore ``stdout`` and ``stderr`` to their original values, so that
+Colorama is disabled. To resume using Colorama again, call ``reinit()``; it is
+cheaper than calling ``init()`` again (but does the same thing).
+
+Most users should depend on ``colorama >= 0.4.6``, and use
+``just_fix_windows_console``. The old ``init`` interface will be supported
+indefinitely for backwards compatibility, but we don't plan to fix any issues
+with it, also for backwards compatibility.
+
+Colored Output
+..............
+
+Cross-platform printing of colored text can then be done using Colorama's
+constant shorthand for ANSI escape sequences. These are deliberately
+rudimentary, see below.
+
+.. code-block:: python
+
+    from colorama import Fore, Back, Style
+    print(Fore.RED + 'some red text')
+    print(Back.GREEN + 'and with a green background')
+    print(Style.DIM + 'and in dim text')
+    print(Style.RESET_ALL)
+    print('back to normal now')
+
+...or simply by manually printing ANSI sequences from your own code:
+
+.. code-block:: python
+
+    print('\033[31m' + 'some red text')
+    print('\033[39m') # and reset to default color
+
+...or, Colorama can be used in conjunction with existing ANSI libraries
+such as the venerable `Termcolor <https://pypi.org/project/termcolor/>`_
+the fabulous `Blessings <https://pypi.org/project/blessings/>`_,
+or the incredible `_Rich <https://pypi.org/project/rich/>`_.
+
+If you wish Colorama's Fore, Back and Style constants were more capable,
+then consider using one of the above highly capable libraries to generate
+colors, etc, and use Colorama just for its primary purpose: to convert
+those ANSI sequences to also work on Windows:
+
+SIMILARLY, do not send PRs adding the generation of new ANSI types to Colorama.
+We are only interested in converting ANSI codes to win32 API calls, not
+shortcuts like the above to generate ANSI characters.
+
+.. code-block:: python
+
+    from colorama import just_fix_windows_console
+    from termcolor import colored
+
+    # use Colorama to make Termcolor work on Windows too
+    just_fix_windows_console()
+
+    # then use Termcolor for all colored text output
+    print(colored('Hello, World!', 'green', 'on_red'))
+
+Available formatting constants are::
+
+    Fore: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET.
+    Back: BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE, RESET.
+    Style: DIM, NORMAL, BRIGHT, RESET_ALL
+
+``Style.RESET_ALL`` resets foreground, background, and brightness. Colorama will
+perform this reset automatically on program exit.
+
+These are fairly well supported, but not part of the standard::
+
+    Fore: LIGHTBLACK_EX, LIGHTRED_EX, LIGHTGREEN_EX, LIGHTYELLOW_EX, LIGHTBLUE_EX, LIGHTMAGENTA_EX, LIGHTCYAN_EX, LIGHTWHITE_EX
+    Back: LIGHTBLACK_EX, LIGHTRED_EX, LIGHTGREEN_EX, LIGHTYELLOW_EX, LIGHTBLUE_EX, LIGHTMAGENTA_EX, LIGHTCYAN_EX, LIGHTWHITE_EX
+
+Cursor Positioning
+..................
+
+ANSI codes to reposition the cursor are supported. See ``demos/demo06.py`` for
+an example of how to generate them.
+
+Init Keyword Args
+.................
+
+``init()`` accepts some ``**kwargs`` to override default behaviour.
+
+init(autoreset=False):
+    If you find yourself repeatedly sending reset sequences to turn off color
+    changes at the end of every print, then ``init(autoreset=True)`` will
+    automate that:
+
+    .. code-block:: python
+
+        from colorama import init
+        init(autoreset=True)
+        print(Fore.RED + 'some red text')
+        print('automatically back to default color again')
+
+init(strip=None):
+    Pass ``True`` or ``False`` to override whether ANSI codes should be
+    stripped from the output. The default behaviour is to strip if on Windows
+    or if output is redirected (not a tty).
+
+init(convert=None):
+    Pass ``True`` or ``False`` to override whether to convert ANSI codes in the
+    output into win32 calls. The default behaviour is to convert if on Windows
+    and output is to a tty (terminal).
+
+init(wrap=True):
+    On Windows, Colorama works by replacing ``sys.stdout`` and ``sys.stderr``
+    with proxy objects, which override the ``.write()`` method to do their work.
+    If this wrapping causes you problems, then this can be disabled by passing
+    ``init(wrap=False)``. The default behaviour is to wrap if ``autoreset`` or
+    ``strip`` or ``convert`` are True.
+
+    When wrapping is disabled, colored printing on non-Windows platforms will
+    continue to work as normal. To do cross-platform colored output, you can
+    use Colorama's ``AnsiToWin32`` proxy directly:
+
+    .. code-block:: python
+
+        import sys
+        from colorama import init, AnsiToWin32
+        init(wrap=False)
+        stream = AnsiToWin32(sys.stderr).stream
+
+        # Python 2
+        print >>stream, Fore.BLUE + 'blue text on stderr'
+
+        # Python 3
+        print(Fore.BLUE + 'blue text on stderr', file=stream)
+
+Recognised ANSI Sequences
+.........................
+
+ANSI sequences generally take the form::
+
+    ESC [ <param> ; <param> ... <command>
+
+Where ``<param>`` is an integer, and ``<command>`` is a single letter. Zero or
+more params are passed to a ``<command>``. If no params are passed, it is
+generally synonymous with passing a single zero. No spaces exist in the
+sequence; they have been inserted here simply to read more easily.
+
+The only ANSI sequences that Colorama converts into win32 calls are::
+
+    ESC [ 0 m       # reset all (colors and brightness)
+    ESC [ 1 m       # bright
+    ESC [ 2 m       # dim (looks same as normal brightness)
+    ESC [ 22 m      # normal brightness
+
+    # FOREGROUND:
+    ESC [ 30 m      # black
+    ESC [ 31 m      # red
+    ESC [ 32 m      # green
+    ESC [ 33 m      # yellow
+    ESC [ 34 m      # blue
+    ESC [ 35 m      # magenta
+    ESC [ 36 m      # cyan
+    ESC [ 37 m      # white
+    ESC [ 39 m      # reset
+
+    # BACKGROUND
+    ESC [ 40 m      # black
+    ESC [ 41 m      # red
+    ESC [ 42 m      # green
+    ESC [ 43 m      # yellow
+    ESC [ 44 m      # blue
+    ESC [ 45 m      # magenta
+    ESC [ 46 m      # cyan
+    ESC [ 47 m      # white
+    ESC [ 49 m      # reset
+
+    # cursor positioning
+    ESC [ y;x H     # position cursor at x across, y down
+    ESC [ y;x f     # position cursor at x across, y down
+    ESC [ n A       # move cursor n lines up
+    ESC [ n B       # move cursor n lines down
+    ESC [ n C       # move cursor n characters forward
+    ESC [ n D       # move cursor n characters backward
+
+    # clear the screen
+    ESC [ mode J    # clear the screen
+
+    # clear the line
+    ESC [ mode K    # clear the line
+
+Multiple numeric params to the ``'m'`` command can be combined into a single
+sequence::
+
+    ESC [ 36 ; 45 ; 1 m     # bright cyan text on magenta background
+
+All other ANSI sequences of the form ``ESC [ <param> ; <param> ... <command>``
+are silently stripped from the output on Windows.
+
+Any other form of ANSI sequence, such as single-character codes or alternative
+initial characters, are not recognised or stripped. It would be cool to add
+them though. Let me know if it would be useful for you, via the Issues on
+GitHub.
+
+Status & Known Problems
+-----------------------
+
+I've personally only tested it on Windows XP (CMD, Console2), Ubuntu
+(gnome-terminal, xterm), and OS X.
+
+Some valid ANSI sequences aren't recognised.
+
+If you're hacking on the code, see `README-hacking.md`_. ESPECIALLY, see the
+explanation there of why we do not want PRs that allow Colorama to generate new
+types of ANSI codes.
+
+See outstanding issues and wish-list:
+https://github.com/tartley/colorama/issues
+
+If anything doesn't work for you, or doesn't do what you expected or hoped for,
+I'd love to hear about it on that issues list, would be delighted by patches,
+and would be happy to grant commit access to anyone who submits a working patch
+or two.

+dill: serialize all of Python
+-----------------------------
+
+About Dill
+==========
+
+``dill`` extends Python's ``pickle`` module for serializing and de-serializing
+Python objects to the majority of the built-in Python types. Serialization
+is the process of converting an object to a byte stream, and the inverse
+of which is converting a byte stream back to a Python object hierarchy.
+
+``dill`` provides the user the same interface as the ``pickle`` module, and
+also includes some additional features. In addition to pickling Python
+objects, ``dill`` provides the ability to save the state of an interpreter
+session in a single command.  Hence, it would be feasible to save an
+interpreter session, close the interpreter, ship the pickled file to
+another computer, open a new interpreter, unpickle the session and
+thus continue from the 'saved' state of the original interpreter
+session.
+
+``dill`` can be used to store Python objects to a file, but the primary
+usage is to send Python objects across the network as a byte stream.
+``dill`` is quite flexible, and allows arbitrary user defined classes
+and functions to be serialized.  Thus ``dill`` is not intended to be
+secure against erroneously or maliciously constructed data. It is
+left to the user to decide whether the data they unpickle is from
+a trustworthy source.
+
+``dill`` is part of ``pathos``, a Python framework for heterogeneous computing.
+``dill`` is in active development, so any user feedback, bug reports, comments,
+or suggestions are highly appreciated.  A list of issues is located at
+https://github.com/uqfoundation/dill/issues, with a legacy list maintained at
+https://uqfoundation.github.io/project/pathos/query.
+
+
+Major Features
+==============
+
+``dill`` can pickle the following standard types:
+
+    - none, type, bool, int, float, complex, bytes, str,
+    - tuple, list, dict, file, buffer, builtin,
+    - Python classes, namedtuples, dataclasses, metaclasses,
+    - instances of classes,
+    - set, frozenset, array, functions, exceptions
+
+``dill`` can also pickle more 'exotic' standard types:
+
+    - functions with yields, nested functions, lambdas,
+    - cell, method, unboundmethod, module, code, methodwrapper,
+    - methoddescriptor, getsetdescriptor, memberdescriptor, wrapperdescriptor,
+    - dictproxy, slice, notimplemented, ellipsis, quit
+
+``dill`` cannot yet pickle these standard types:
+
+    - frame, generator, traceback
+
+``dill`` also provides the capability to:
+
+    - save and load Python interpreter sessions
+    - save and extract the source code from functions and classes
+    - interactively diagnose pickling errors
+
+
+Current Release
+===============
+
+The latest released version of ``dill`` is available from:
+
+    https://pypi.org/project/dill
+
+``dill`` is distributed under a 3-clause BSD license.

+
+
+Installation
+============
+
+``dill`` can be installed with ``pip``::
+
+    $ pip install dill
+
+To optionally include the ``objgraph`` diagnostic tool in the install::
+
+    $ pip install dill[graph]
+
+To optionally include the ``gprof2dot`` diagnostic tool in the install::
+
+    $ pip install dill[profile]
+
+For windows users, to optionally install session history tools::
+
+    $ pip install dill[readline]
+
+
+Requirements
+============
+
+``dill`` requires:
+
+    - ``python`` (or ``pypy``), **>=3.8**
+    - ``setuptools``, **>=42**
+
+Optional requirements:
+
+    - ``objgraph``, **>=1.7.2**
+    - ``gprof2dot``, **>=2022.7.29**
+    - ``pyreadline``, **>=1.7.1** (on windows)
+
+
+Basic Usage
+===========
+
+``dill`` is a drop-in replacement for ``pickle``. Existing code can be
+updated to allow complete pickling using::
+
+    >>> import dill as pickle
+
+or::
+
+    >>> from dill import dumps, loads
+
+``dumps`` converts the object to a unique byte string, and ``loads`` performs
+the inverse operation::
+
+    >>> squared = lambda x: x**2
+    >>> loads(dumps(squared))(3)
+    9
+
+There are a number of options to control serialization which are provided
+as keyword arguments to several ``dill`` functions:
+
+* with *protocol*, the pickle protocol level can be set. This uses the
+  same value as the ``pickle`` module, *DEFAULT_PROTOCOL*.
+* with *byref=True*, ``dill`` to behave a lot more like pickle with
+  certain objects (like modules) pickled by reference as opposed to
+  attempting to pickle the object itself.
+* with *recurse=True*, objects referred to in the global dictionary are
+  recursively traced and pickled, instead of the default behavior of
+  attempting to store the entire global dictionary.
+* with *fmode*, the contents of the file can be pickled along with the file
+  handle, which is useful if the object is being sent over the wire to a
+  remote system which does not have the original file on disk. Options are
+  *HANDLE_FMODE* for just the handle, *CONTENTS_FMODE* for the file content
+  and *FILE_FMODE* for content and handle.
+* with *ignore=False*, objects reconstructed with types defined in the
+  top-level script environment use the existing type in the environment
+  rather than a possibly different reconstructed type.
+
+The default serialization can also be set globally in *dill.settings*.
+Thus, we can modify how ``dill`` handles references to the global dictionary
+locally or globally::
+
+    >>> import dill.settings
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    False
+    >>> dill.settings['recurse'] = True
+    >>> dumps(absolute) == dumps(absolute, recurse=True)
+    True
+
+``dill`` also includes source code inspection, as an alternate to pickling::
+
+    >>> import dill.source
+    >>> print(dill.source.getsource(squared))
+    squared = lambda x:x**2
+
+To aid in debugging pickling issues, use *dill.detect* which provides
+tools like pickle tracing::
+
+    >>> import dill.detect
+    >>> with dill.detect.trace():
+    >>>     dumps(squared)
+    ┬ F1: <function <lambda> at 0x7fe074f8c280>
+    ├┬ F2: <function _create_function at 0x7fe074c49c10>
+    │└ # F2 [34 B]
+    ├┬ Co: <code object <lambda> at 0x7fe07501eb30, file "<stdin>", line 1>
+    │├┬ F2: <function _create_code at 0x7fe074c49ca0>
+    ││└ # F2 [19 B]
+    │└ # Co [87 B]
+    ├┬ D1: <dict object at 0x7fe0750d4680>
+    │└ # D1 [22 B]
+    ├┬ D2: <dict object at 0x7fe074c5a1c0>
+    │└ # D2 [2 B]
+    ├┬ D2: <dict object at 0x7fe074f903c0>
+    │├┬ D2: <dict object at 0x7fe074f8ebc0>
+    ││└ # D2 [2 B]
+    │└ # D2 [23 B]
+    └ # F1 [180 B]
+
+With trace, we see how ``dill`` stored the lambda (``F1``) by first storing
+``_create_function``, the underlying code object (``Co``) and ``_create_code``
+(which is used to handle code objects), then we handle the reference to
+the global dict (``D2``) plus other dictionaries (``D1`` and ``D2``) that
+save the lambda object's state. A ``#`` marks when the object is actually stored.
+
+
+More Information
+================
+
+Probably the best way to get started is to look at the documentation at
+http://dill.rtfd.io. Also see ``dill.tests`` for a set of scripts that
+demonstrate how ``dill`` can serialize different Python objects. You can
+run the test suite with ``python -m dill.tests``. The contents of any
+pickle file can be examined with ``undill``.  As ``dill`` conforms to
+the ``pickle`` interface, the examples and documentation found at
+http://docs.python.org/library/pickle.html also apply to ``dill``
+if one will ``import dill as pickle``. The source code is also generally
+well documented, so further questions may be resolved by inspecting the
+code itself. Please feel free to submit a ticket on github, or ask a
+question on stackoverflow (**@Mike McKerns**).
+If you would like to share how you use ``dill`` in your work, please send
+an email (to **mmckerns at uqfoundation dot org**).
