+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.

+
+0.15.85 (2019-01-08):
+  - 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):

+
+0.15.82 (2018-12-28):

+
+0.15.80 (2018-11-26):
+  - fix issue emitting BEL character when round-tripping invalid folded input
+    (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):
+  - fix setup issue for 3.8 (reported by `Sidney Kuyateh 
+    <https://bitbucket.org/autinerd/>`__)
+
+0.15.77 (2018-11-09):
+  - setting `yaml.sort_base_mapping_type_on_output = False`, will prevent
+    explicit sorting by keys in the base representer of mappings. Roundtrip
+    already did not do this. Usage only makes real sense for Python 3.6+
+    (feature request by `Sebastian Gerber <https://bitbucket.org/spacemanspiff2007/>`__).
+  - implement Python version check in YAML metadata in ``_test/test_z_data.py``
+

+
+0.15.75 (2018-10-27):
+  - fix issue with single '?' scalar (reported by `Terrance 
+    <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):
+  - fix irregular output on pre-comment in sequence within sequence (reported
+    by `Thorsten Kampe <https://bitbucket.org/thorstenkampe/>`__)
+  - allow non-compact (i.e. next line) dumping sequence/mapping within sequence.
+
+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. 
+    ``_test/test_z_data.py`` processes these.
+  - fix regression where handcrafted CommentedMaps could not be initiated (reported by 
+    `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>`__)
+
+0.15.69 (2018-09-20):
+  - fix issue with dump_all gobbling end-of-document comments on parsing
+    (reported by `Pierre B. <https://bitbucket.org/octplane/>`__)

+  - fix issue with parsabel, but incorrect output with nested flow-style sequences
+    (reported by `Dougal Seeley <https://bitbucket.org/dseeley/>`__)

+    (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):
+  - fix broken 3.6 manylinux1, the result of an unclean ``build`` (reported by 
+    `Roman Sichnyi <https://bitbucket.org/rsichnyi-gl/>`__)
+
+
+0.15.46 (2018-07-29):
+  - fixed DeprecationWarning for importing from ``collections`` on 3.7
+    (issue 210, reported by `Reinoud Elhorst
+    <https://bitbucket.org/reinhrst/>`__). It was `difficult to find
+    why tox/pytest did not report
+    <https://stackoverflow.com/q/51573204/1307905>`__ and as time
+    consuming to actually `fix
+    <https://stackoverflow.com/a/51573205/1307905>`__ the tests.
+
+0.15.45 (2018-07-26):
+  - After adding failing test for ``YAML.load_all(Path())``, remove StopIteration 
+    (PR provided by `Zachary Buhman <https://bitbucket.org/buhman/>`__,
+    also reported by `Steven Hiscocks <https://bitbucket.org/sdhiscocks/>`__.
+
+0.15.44 (2018-07-14):
+  - Correct loading plain scalars consisting of numerals only and
+    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
+    <https://bitbucket.org/minrk/>`__, that prompted this chance.
+
+0.15.43 (2018-07-12):
+  - merge PR33: Python2.7 on Windows is narrow, but has no
+    ``sysconfig.get_config_var('Py_UNICODE_SIZE')``. (merge provided by

+  - fix regression showing only on narrow Python 2.7 (py27mu) builds
+    (with help from
+    `Marcel Bargull <https://bitbucket.org/mbargull/>`__ and
+    `Colm O'Connor <https://bitbucket.org/colmoconnorgithub/>`__).
+  - run pre-commit ``tox`` on Python 2.7 wide and narrow, as well as
+    3.4/3.5/3.6/3.7/pypy
+
+0.15.41 (2018-06-27):
+  - add detection of C-compile failure (investigation prompted by
+    `StackOverlow <https://stackoverflow.com/a/51057399/1307905>`__ by
+    `Emmanuel Blot <https://stackoverflow.com/users/8233409/emmanuel-blot>`__),
+    which was removed while no longer dependent on ``libyaml``, C-extensions
+    compilation still needs a compiler though.
+
+0.15.40 (2018-06-18):
+  - added links to landing places as suggested in issue 190 by
+    `KostisA <https://bitbucket.org/ankostis/>`__

+  - fix issue 187, incompatibility of C extension with 3.7 (reported by
+    Daniel Blanchard)
+
+0.15.35 (2017-12-03):
+  - allow ``None`` as stream when specifying ``transform`` parameters to
+    ``YAML.dump()``.
+    This is useful if the transforming function doesn't return a meaningful value
+    (inspired by `StackOverflow <https://stackoverflow.com/q/47614862/1307905>`__ by
+    `rsaw <https://stackoverflow.com/users/406281/rsaw>`__).

+  - fix for issue 157: CDumper not dumping floats (reported by Jan Smitka)
+
+0.15.33 (2017-08-31):
+  - support for "undefined" round-tripping tagged scalar objects (in addition to
+    tagged mapping object). Inspired by a use case presented by Matthew Patton
+    on `StackOverflow <https://stackoverflow.com/a/45967047/1307905>`__.
+  - fix issue 148: replace cryptic error message when using !!timestamp with an
+    incorrectly formatted or non- scalar. Reported by FichteFoll.
+
+0.15.32 (2017-08-21):
+  - allow setting ``yaml.default_flow_style = None`` (default: ``False``) for
+    for ``typ='rt'``.
+  - fix for issue 149: multiplications on ``ScalarFloat`` now return ``float``
+    (reported by jan.brezina@tul.cz)
+
+0.15.31 (2017-08-15):
+  - fix Comment dumping
+
+0.15.30 (2017-08-14):

+0.15.28 (2017-08-13):
+  - fix issue #61: merge of merge cannot be __repr__-ed (reported by Tal Liron)
+
+0.15.27 (2017-08-13):

+    (reported by nowox)
+  - fix lists within lists which would make comments disappear
+
+0.15.26 (2017-08-10):
+  - fix for disappearing comment after empty flow sequence (reported by
+    oit-tzhimmash)

+  - added ScalarFloat which supports roundtripping of 23.1, 23.100,
+    42.00E+56, 0.0, -0.0 etc. while keeping the format. Underscores in mantissas
+    are not preserved/supported (yet, is anybody using that?).
+  - (finally) fixed longstanding issue 23 (reported by `Antony Sottile
+    <https://bitbucket.org/asottile/>`__), now handling comment between block
+    mapping key and value correctly
+  - warn on YAML 1.1 float input that is incorrect (triggered by invalid YAML

+  - fix for load_all in combination with zero indent block style literal
+    (``pure=True`` only!)
+
+0.15.18 (2017-07-04):
+  - missing ``pure`` attribute on ``YAML`` useful for implementing `!include` tag
+    constructor for `including YAML files in a YAML file
+    <https://stackoverflow.com/a/44913652/1307905>`__
+  - some documentation improvements
+  - trigger of doc build on new revision
+
+0.15.17 (2017-07-03):

+  - fix for issue 133, in setup.py: change ModuleNotFoundError to
+    ImportError (reported and fix by
+    `Asley Drake  <https://github.com/aldraco>`__)
+
+0.15.13 (2017-06-24):
+  - suppress duplicate key warning on mappings with merge keys (reported by
+    Cameron Sweeney)
+
+0.15.12 (2017-06-24):

+    Cameron Sweeney)
+
+0.15.11 (2017-06-24):
+  - fix for issue 130, regression in nested merge keys (reported by
+    `David Fee <https://bitbucket.org/dfee/>`__)
+
+0.15.10 (2017-06-23):
+  - top level PreservedScalarString not indented if not explicitly asked to
+  - remove Makefile (not very useful anyway)
+  - some mypy additions
+
+0.15.9 (2017-06-16):
+  - fix for issue 127: tagged scalars were always quoted and seperated
+    by a newline when in a block sequence (reported and largely fixed by
+    `Tommy Wang <https://bitbucket.org/twang817/>`__)

+0.15.8 (2017-06-15):
+  - allow plug-in install via ``install ruamel.yaml[jinja2]``

+0.15.7 (2017-06-14):
+  - add plug-in mechanism for load/dump pre resp. post-processing
+
+0.15.6 (2017-06-10):
+  - a set() with duplicate elements now throws error in rt loading
+  - support for toplevel column zero literal/folded scalar in explicit documents
+
+0.15.5 (2017-06-08):
+  - 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
+
+0.15.0 (2017-06-04):
+  - 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
+    Constantine Evans <cevans@evanslabs.org>)
+
+0.14.11 (2017-05-01):
+  - fix for issue 103 allowing implicit documents after document end marker line (``...``)
+    in YAML 1.2
+
+0.14.10 (2017-04-26):
+  - fix problem with emitting using cyaml
+
+0.14.9 (2017-04-22):
+  - remove dependency on ``typing`` while still supporting ``mypy``
+    (http://stackoverflow.com/a/43516781/1307905)
+  - fix unclarity in doc that stated 2.6 is supported (reported by feetdust)
+
+0.14.8 (2017-04-19):
+  - fix Text not available on 3.5.0 and 3.5.1, now proactively setting version guards
+    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
