-ruamel.yaml
-===========
-
-``ruamel.yaml`` is a YAML 1.2 loader/dumper package for Python.
-
-:version:       0.16.0
-:updated:       2019-07-25
-:documentation: http://yaml.readthedocs.io
-:repository:    https://bitbucket.org/ruamel/yaml
-:pypi:          https://pypi.org/project/ruamel.yaml/
-
-
-Starting with version 0.15.0 the way YAML files are loaded and dumped
-is changing. See the API doc for details.  Currently existing
-functionality will throw a warning before being changed/removed.
-**For production systems you should pin the version being used with
-``ruamel.yaml<=0.15``**. There might be bug fixes in the 0.14 series,
-but new functionality is likely only to be available via the new API.
-
-If your package uses ``ruamel.yaml`` and is not listed on PyPI, drop
-me an email, preferably with some information on how you use the
-package (or a link to bitbucket/github) and I'll keep you informed
-when the status of the API is stable enough to make the transition.

-  - the types used by ``SafeConstructor`` for mappings and sequences can
-    now by set by assigning to ``XXXConstructor.yaml_base_dict_type``
-    (and ``..._list_type``), preventing the need to copy two methods
-    with 50+ lines that had ``var = {}`` hardcoded.  (Implemented to
-    help solve an feature request by `Anthony Sottile
-    <https://bitbucket.org/asottile/>`__ in an easier way)
-
-0.15.84 (2019-01-07):

-    (reported by Isaac on `StackOverflow <https://stackoverflow.com/a/53471217/1307905>`__)
-
-0.15.79 (2018-11-21):
-  - fix issue with anchors nested deeper than alias (reported by gaFF on
-    `StackOverflow <https://stackoverflow.com/a/53397781/1307905>`__)
-
-0.15.78 (2018-11-15):

-    <https://bitbucket.org/autinerd/>`__)
-
-0.15.77 (2018-11-09):
-  - setting `yaml.sort_base_mapping_type_on_output = False`, will prevent

-    <https://bitbucket.org/OllieTerrance/>`__)
-  - fix issue with duplicate merge keys (prompted by `answering 
-    <https://stackoverflow.com/a/52852106/1307905>`__ a 
-    `StackOverflow question <https://stackoverflow.com/q/52851168/1307905>`__
-    by `math <https://stackoverflow.com/users/1355634/math>`__)
-
-0.15.74 (2018-10-17):
-  - fix dropping of comment on rt before sequence item that is sequence item
-    (reported by `Thorsten Kampe <https://bitbucket.org/thorstenkampe/>`__)
-
-0.15.73 (2018-10-16):

-
-0.15.72 (2018-10-06):
-  - fix regression on explicit 1.1 loading with the C based scanner/parser
-    (reported by `Tomas Vavra <https://bitbucket.org/xtomik/>`__)
-
-0.15.71 (2018-09-26):
-  - some of the tests now live in YAML files in the 
-    `yaml.data <https://bitbucket.org/ruamel/yaml.data>`__ repository.

-    `Dan Helfman <https://bitbucket.org/dhelfman/>`__)
-  - fix regression with non-root literal scalars that needed indent indicator
-    (reported by `Clark Breyman <https://bitbucket.org/clarkbreyman/>`__)
-  - tag:yaml.org,2002:python/object/apply now also uses __qualname__ on PY3
-    (reported by `Douglas RAILLARD <https://bitbucket.org/DouglasRaillard/>`__)
-  - issue with self-referring object creation
-    (reported and fix by `Douglas RAILLARD <https://bitbucket.org/DouglasRaillard/>`__)
-
-0.15.70 (2018-09-21):
-  - reverted CommentedMap and CommentedSeq to subclass ordereddict resp. list,
-    reimplemented merge maps so that both ``dict(**commented_map_instance)`` and JSON
-    dumping works. This also allows checking with ``isinstance()`` on ``dict`` resp. ``list``.
-    (Proposed by `Stuart Berg <https://bitbucket.org/stuarteberg/>`__, with feedback
-    from `blhsing <https://stackoverflow.com/users/6890912/blhsing>`__ on
-    `StackOverflow <https://stackoverflow.com/q/52314186/1307905>`__)

-    (reported by `Douglas RAILLARD <https://bitbucket.org/DouglasRaillard/>`__)
-
-0.15.67 (2018-09-19):
-  - fix issue with extra space inserted with non-root literal strings 
-    (Issue reported and PR with fix provided by 
-    `Naomi Seyfer <https://bitbucket.org/sixolet/>`__.)
-
-0.15.66 (2018-09-07):
-  - fix issue with fold indicating characters inserted in safe_load-ed folded strings
-    (reported by `Maximilian Hils <https://bitbucket.org/mhils/>`__).
-
-0.15.65 (2018-09-07):
-  - fix issue #232 revert to throw ParserError for unexcpected ``]``
-    and ``}`` instead of IndexError. (Issue reported and PR with fix
-    provided by `Naomi Seyfer <https://bitbucket.org/sixolet/>`__.)
-  - added ``key`` and ``reverse`` parameter (suggested by Jannik Klemm via email)
-  - indent root level literal scalars that have directive or document end markers
-    at the beginning of a line
-
-0.15.64 (2018-08-30):
-  - support round-trip of tagged sequences: ``!Arg [a, {b: 1}]``
-  - single entry mappings in flow sequences now written by default without braces,
-    set ``yaml.brace_single_entry_mapping_in_flow_sequence=True`` to force
-    getting ``[a, {b: 1}, {c: {d: 2}}]`` instead of the default ``[a, b: 1, c: {d: 2}]``
-  - fix issue when roundtripping floats starting with a dot such as ``.5``
-    (reported by `Harrison Gregg <https://bitbucket.org/HarrisonGregg/>`__)
-
-0.15.63 (2018-08-29):
-  - small fix only necessary for Windows users that don't use wheels.
-
-0.15.62 (2018-08-29):
-  - C based reader/scanner & emitter now allow setting of 1.2 as YAML version.
-    ** The loading/dumping is still YAML 1.1 code**, so use the common subset of
-    YAML 1.2 and 1.1 (reported by `Ge Yang <https://bitbucket.org/yangge/>`__)
-
-0.15.61 (2018-08-23):
-  - support for round-tripping folded style scalars (initially requested 
-    by `Johnathan Viduchinsky <https://bitbucket.org/johnathanvidu/>`__)
-  - update of C code
-  - speed up of scanning (~30% depending on the input)
-
-0.15.60 (2018-08-18):
-  - again allow single entry map in flow sequence context (reported by 
-    `Lee Goolsbee <https://bitbucket.org/lgoolsbee/>`__)
-  - cleanup for mypy 
-  - spurious print in library (reported by 
-    `Lele Gaifax <https://bitbucket.org/lele/>`__), now automatically checked 
-
-0.15.59 (2018-08-17):
-  - issue with C based loader and leading zeros (reported by 
-    `Tom Hamilton Stubber <https://bitbucket.org/TomHamiltonStubber/>`__)
-
-0.15.58 (2018-08-17):
-  - simple mappings can now be used as keys when round-tripping::
-
-      {a: 1, b: 2}: hello world
-
-    although using the obvious operations (del, popitem) on the key will
-    fail, you can mutilate it by going through its attributes. If you load the
-    above YAML in `d`, then changing the value is cumbersome:
-
-        d = {CommentedKeyMap([('a', 1), ('b', 2)]): "goodbye"}
-
-    and changing the key even more so:
-
-        d[CommentedKeyMap([('b', 1), ('a', 2)])] = d.pop(
-                     CommentedKeyMap([('a', 1), ('b', 2)]))
-
-    (you can use a `dict` instead of a list of tuples (or ordereddict), but that might result
-    in a different order, of the keys of the key, in the output)
-  - check integers to dump with 1.2 patterns instead of 1.1 (reported by 
-    `Lele Gaifax <https://bitbucket.org/lele/>`__)
-
-
-0.15.57 (2018-08-15):
-  - Fix that CommentedSeq could no longer be used in adding or do a sort
-    (reported by `Christopher Wright <https://bitbucket.org/CJ-Wright4242/>`__)
-
-0.15.56 (2018-08-15):
-  - fix issue with ``python -O`` optimizing away code (reported, and detailed cause
-    pinpointed, by `Alex Grönholm <https://bitbucket.org/agronholm/>`__)
-
-0.15.55 (2018-08-14):
-  - unmade ``CommentedSeq`` a subclass of ``list``. It is now
-    indirectly a subclass of the standard
-    ``collections.abc.MutableSequence`` (without .abc if you are
-    still on Python2.7). If you do ``isinstance(yaml.load('[1, 2]'),
-    list)``) anywhere in your code replace ``list`` with
-    ``MutableSequence``.  Directly, ``CommentedSeq`` is a subclass of
-    the abstract baseclass ``ruamel.yaml.compat.MutableScliceableSequence``,
-    with the result that *(extended) slicing is supported on 
-    ``CommentedSeq``*.
-    (reported by `Stuart Berg <https://bitbucket.org/stuarteberg/>`__)
-  - duplicate keys (or their values) with non-ascii now correctly
-    report in Python2, instead of raising a Unicode error.
-    (Reported by `Jonathan Pyle <https://bitbucket.org/jonathan_pyle/>`__)
-
-0.15.54 (2018-08-13):
-  - fix issue where a comment could pop-up twice in the output (reported by 
-    `Mike Kazantsev <https://bitbucket.org/mk_fg/>`__ and by 
-    `Nate Peterson <https://bitbucket.org/ndpete21/>`__)
-  - fix issue where JSON object (mapping) without spaces was not parsed
-    properly (reported by `Marc Schmidt <https://bitbucket.org/marcj/>`__)
-  - fix issue where comments after empty flow-style mappings were not emitted
-    (reported by `Qinfench Chen <https://bitbucket.org/flyin5ish/>`__)
-
-0.15.53 (2018-08-12):
-  - fix issue with flow style mapping with comments gobbled newline (reported
-    by `Christopher Lambert <https://bitbucket.org/XN137/>`__)
-  - fix issue where single '+' under YAML 1.2 was interpreted as
-    integer, erroring out (reported by `Jethro Yu
-    <https://bitbucket.org/jcppkkk/>`__)
-
-0.15.52 (2018-08-09):
-  - added `.copy()` mapping representation for round-tripping
-    (``CommentedMap``) to fix incomplete copies of merged mappings
-    (reported by `Will Richards
-    <https://bitbucket.org/will_richards/>`__) 
-  - Also unmade that class a subclass of ordereddict to solve incorrect behaviour
-    for ``{**merged-mapping}`` and ``dict(**merged-mapping)`` (reported independently by
-    `Tim Olsson <https://bitbucket.org/tgolsson/>`__ and 
-    `Filip Matzner <https://bitbucket.org/FloopCZ/>`__)
-
-0.15.51 (2018-08-08):
-  - Fix method name dumps (were not dotted) and loads (reported by `Douglas Raillard 
-    <https://bitbucket.org/DouglasRaillard/>`__)
-  - Fix spurious trailing white-space caused when the comment start
-    column was no longer reached and there was no actual EOL comment
-    (e.g. following empty line) and doing substitutions, or when
-    quotes around scalars got dropped.  (reported by `Thomas Guillet
-    <https://bitbucket.org/guillett/>`__)
-
-0.15.50 (2018-08-05):
-  - Allow ``YAML()`` as a context manager for output, thereby making it much easier
-    to generate multi-documents in a stream. 
-  - Fix issue with incorrect type information for `load()` and `dump()` (reported 
-    by `Jimbo Jim <https://bitbucket.org/jimbo1qaz/>`__)
-
-0.15.49 (2018-08-05):
-  - fix preservation of leading newlines in root level literal style scalar,
-    and preserve comment after literal style indicator (``|  # some comment``)
-    Both needed for round-tripping multi-doc streams in 
-    `ryd <https://pypi.org/project/ryd/>`__.
-
-0.15.48 (2018-08-03):
-  - housekeeping: ``oitnb`` for formatting, mypy 0.620 upgrade and conformity
-
-0.15.47 (2018-07-31):

-    why tox/pytest did not report
-    <https://stackoverflow.com/q/51573204/1307905>`__ and as time

-    starting with `0`, when not explicitly specifying YAML version
-    1.1. This also fixes the issue about dumping string `'019'` as
-    plain scalars as reported by `Min RK

-  - repeat `load()` on a single `YAML()` instance would fail.
-
-0.15.4 (2017-06-08):
-  - `transform` parameter on dump that expects a function taking a
-    string and returning a string. This allows transformation of the output
-    before it is written to stream. This forces creation of the complete output in memory!
-  - some updates to the docs
-
-0.15.3 (2017-06-07):
-  - No longer try to compile C extensions on Windows. Compilation can be forced by setting
-    the environment variable `RUAMEL_FORCE_EXT_BUILD` to some value
-    before starting the `pip install`.
-
-0.15.2 (2017-06-07):
-  - update to conform to mypy 0.511: mypy --strict
-
-0.15.1 (2017-06-07):
-  - `duplicate keys  <http://yaml.readthedocs.io/en/latest/api.html#duplicate-keys>`__
-    in mappings generate an error (in the old API this change generates a warning until 0.16)
-  - dependecy on ruamel.ordereddict for 2.7 now via extras_require

-  - it is now allowed to pass in a ``pathlib.Path`` as "stream" parameter to all
-    load/dump functions
-  - passing in a non-supported object (e.g. a string) as "stream" will result in a
-    much more meaningful YAMLStreamError.
-  - assigning a normal string value to an existing CommentedMap key or CommentedSeq
-    element will result in a value cast to the previous value's type if possible.
-  - added ``YAML`` class for new API
-
-0.14.12 (2017-05-14):
-  - fix for issue 119, deepcopy not returning subclasses (reported and PR by

-    on all files (reported by `João Paulo Magalhães <https://bitbucket.org/jpmag/>`__)
-
-0.14.7 (2017-04-18):
-  - round trip of integers (decimal, octal, hex, binary) now preserve
-    leading zero(s) padding and underscores. Underscores are presumed
-    to be at regular distances (i.e. ``0o12_345_67`` dumps back as
-    ``0o1_23_45_67`` as the space from the last digit to the
-    underscore before that is the determining factor).
-
-0.14.6 (2017-04-14):
-  - binary, octal and hex integers are now preserved by default. This
-    was a known deficiency. Working on this was prompted by the issue report (112)
-    from devnoname120, as well as the additional experience with `.replace()`
-    on `scalarstring` classes.
-  - fix issues 114: cannot install on Buildozer (reported by mixmastamyk).
-    Setting env. var ``RUAMEL_NO_PIP_INSTALL_CHECK`` will suppress ``pip``-check.
-
-0.14.5 (2017-04-04):
-  - fix issue 109: None not dumping correctly at top level (reported by Andrea Censi)
-  - fix issue 110: .replace on Preserved/DoubleQuoted/SingleQuoted ScalarString
-    would give back "normal" string (reported by sandres23)
-
-0.14.4 (2017-03-31):
-  - fix readme
-
-0.14.3 (2017-03-31):
-  - fix for 0o52 not being a string in YAML 1.1 (reported on
-    `StackOverflow Q&A 43138503 <http://stackoverflow.com/a/43138503/1307905>`__ by
-    `Frank D <http://stackoverflow.com/users/7796630/frank-d>`__)
-
-0.14.2 (2017-03-23):
-  - fix for old default pip on Ubuntu 14.04 (reported by Sébastien Maccagnoni-Munch)
-
-0.14.1 (2017-03-22):
-  - fix Text not available on 3.5.0 and 3.5.1 (reported by Charles Bouchard-Légaré)
-
-0.14.0 (2017-03-21):
-  - updates for mypy --strict
-  - preparation for moving away from inheritance in Loader and Dumper, calls from e.g.
-    the Representer to the Serializer.serialize() are now done via the attribute
-    .serializer.serialize(). Usage of .serialize() outside of Serializer will be
-    deprecated soon
-  - some extra tests on main.py functions
