+
+(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).

+ - 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
+
+(0.13.14) 2017-02-12:
+ - fix for issue 97, clipped block scalar followed by empty lines and comment

+ - fix for issue 93, insert spurious blank line before single line comment
+ between indented sequence elements (reported by Alex)
+
+(0.13.9) 2017-01-18:

+(0.13.1) 2016-11-22:
+ - optimisations on memory usage when loading YAML from large files (py3 -50%, py2 -85%)
+
+(0.13.0) 2016-11-20:
+ - if ``load()`` or ``load_all()`` is called with only a single argument
+ (stream or string)
+ a UnsafeLoaderWarning will be issued once. If appropriate you can surpress this
+ warning by filtering it. Explicitly supplying the ``Loader=ruamel.yaml.Loader``
+ argument, will also prevent it from being issued. You should however consider
+ using ``safe_load()``, ``safe_load_all()`` if your YAML input does not use tags.
+ - allow adding comments before and after keys (based on
+ `StackOveflow Q&A <http://stackoverflow.com/a/40705671/1307905>`_ by

+
+ '''abc
+
+ klm'''
+
+(0.12.14) 2016-09-21:
+ - preserve round-trip sequences that are mapping keys

+ - Z/-5/+01:00 preserved
+
+(0.12.4) 2016-08-19:
+ - Fix for issue 44: missing preserve_quotes keyword argument (reported
+ by M. Crusoe)
+
+(0.12.3) 2016-08-17:
+ - correct 'in' operation for merged CommentedMaps in round-trip mode
+ (implementation inspired by J.Ngo, but original not working for merges)
+ - iteration over round-trip loaded mappings, that contain merges. Also
+ keys(), items(), values() (Py3/Py2) and iterkeys(), iteritems(),
+ itervalues(), viewkeys(), viewitems(), viewvalues() (Py2)
+ - reuse of anchor name now generates warning, not an error. Round-tripping such
+ anchors works correctly. This inherited PyYAML issue was brought to attention
+ by G. Coddut (and was long standing https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515634)

+ruyaml
+======
+
+``ruyaml`` package is a fork of ``ruamel.yaml`` aimed to made in order to
+secure the future of the library, mainly by having a pool of maintainers.
+
+Notes
+=====
+
+- The current version has the same API as the "ruamel.yaml" package.
+ However, it will install the `ruyaml` python module. Thus, simply
+ replace ``from ruamel import yaml`` with ``import ruyaml as yaml``
+ (or equivalent) and you're all set.
+- python3.6 is the minimal version of python supported
+
+
+:version: 0.90.1
+:updated: 2021-06-10
+:documentation: http://ruyaml.readthedocs.io
+:repository: https://github.com/pycontribs/ruyaml.git
+:pypi: https://pypi.org/project/ruyaml/
+
+*The 0.16.13 release was the last that was tested to be working on Python 2.7.
+The 0.17 series will still be tested on Python 3.5, but the 0.18 will not. The
+0.17 series will also stop support for the old PyYAML functions, so a `YAML()` instance
+will need to be created.*
+
+*The 0.17 series will also see changes in how comments are attached during
+roundtrip. This will result in backwards incompatibilities on the `.ca` data and
+it might even be necessary for documented methods that handle comments.*
+
+*Please adjust your dependencies accordingly if necessary. (`ruamel.yaml<0.17`)*
+
+
+Starting with version 0.15.0 the way YAML files are loaded and dumped
+has been changing, see the API doc for details. Currently existing
+functionality will throw a warning before being changed/removed.
+**For production systems already using a pre 0.16 version, you should
+pin the version being used with ``ruamel.yaml<=0.15``** if you cannot
+fully test upgrading to a newer version. For new usage
+pin to the minor version tested ( ``ruamel.yaml<=0.17``) or even to the
+exact version used.
+
+New functionality is usually only available via the new API, so
+make sure you use it and stop using the `ruamel.yaml.safe_load()`,
+`ruamel.yaml.round_trip_load()` and `ruamel.yaml.load()` functions
+(and their `....dump()` counterparts).
+
+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 the repository) and I'll keep you informed
+when the status of the API is stable enough to make the transition.

+ - allow PyOxidisation (`issue 324 <https://sourceforge.net/p/ruamel-yaml/tickets/324/>`__
+ resp. `issue 171 <https://github.com/indygreg/PyOxidizer/issues/171>`__)
+ - replaced Python 2 compatible enforcement of keyword arguments with '*'
+ - the old top level *functions* ``load``, ``safe_load``, ``round_trip_load``,
+ ``dump``, ``safe_dump``, ``round_trip_dump``, ``scan``, ``parse``,
+ ``compose``, ``emit``, ``serialize`` as well as their ``_all`` variants for
+ multi-document streams, now issue a ``PendingDeprecationning`` (e.g. when run
+ from pytest, but also Python is started with ``-Wd``). Use the methods on
+ ``YAML()``, which have been extended.
+ - fix for issue 376: indentation changes could put literal/folded scalar to start
+ before the ``#`` column of a following comment. Effectively making the comment
+ part of the scalar in the output. (reported by
+ `Bence Nagy <https://sourceforge.net/u/underyx/>`__)

++++++++++++++++++++++++++++
+Departure from previous API
++++++++++++++++++++++++++++
+
+With version 0.15.0 ``ruyaml`` starts to depart from the previous (PyYAML) way
+of loading and dumping. During a transition period the original
+``load()`` and ``dump()`` in its various formats will still be supported,
+but this is not guaranteed to be so with the transition to 1.0.
+
+At the latest with 1.0, but possible earlier transition error and
+warning messages will be issued, so any packages depending on
+ruyaml should pin the version with which they are testing.
+
+
+Up to 0.15.0, the loaders (``load()``, ``safe_load()``,
+``round_trip_load()``, ``load_all``, etc.) took, apart from the input
+stream, a ``version`` argument to allow downgrading to YAML 1.1,
+sometimes needed for
+documents without directive. When round-tripping, there was an option to
+preserve quotes.
+
+Up to 0.15.0, the dumpers (``dump()``, ``safe_dump``,
+``round_trip_dump()``, ``dump_all()``, etc.) had a plethora of
+arguments, some inherited from ``PyYAML``, some added in
+``ruyaml``. The only required argument is the ``data`` to be
+dumped. If the stream argument is not provided to the dumper, then a
+string representation is build up in memory and returned to the
+caller.
+
+Starting with 0.15.0 ``load()`` and ``dump()`` are methods on a
+``YAML`` instance and only take the stream,
+resp. the data and stream argument. All other parameters are set on the instance
+of ``YAML`` before calling ``load()`` or ``dump()``
+
+Before 0.15.0::
+
+ from pathlib import Path
+ import ruyaml
+
+ data = ruyaml.safe_load("abc: 1")
+ out = Path('/tmp/out.yaml')
+ with out.open('w') as fp:
+ ruyaml.safe_dump(data, fp, default_flow_style=False)
+
+after::
+
+ from pathlib import Path
+ from ruyaml import YAML
+
+ yaml = YAML(typ='safe')
+ yaml.default_flow_style = False
+ data = yaml.load("abc: 1")
+ out = Path('/tmp/out.yaml')
+ yaml.dump(data, out)
+
+If you previously used a keyword argument ``explicit_start=True`` you
+now do ``yaml.explicit_start = True`` before calling ``dump()``. The
+``Loader`` and ``Dumper`` keyword arguments are not supported that
+way. You can provide the ``typ`` keyword to ``rt`` (default),
+``safe``, ``unsafe`` or ``base`` (for round-trip load/dump, safe_load/dump,
+load/dump resp. using the BaseLoader / BaseDumper. More fine-control
+is possible by setting the attributes ``.Parser``, ``.Constructor``,
+``.Emitter``, etc., to the class of the type to create for that stage
+(typically a subclass of an existing class implementing that).
+
+The default loader (``typ='rt'``) is a direct derivative of the safe loader, without the
+methods to construct arbitrary Python objects that make the ``unsafe`` loader
+unsafe, but with the changes needed for round-trip preservation of comments,
+etc.. For trusted Python classes a constructor can of course be added to the round-trip
+or safe-loader, but this has to be done explicitly (``add_constructor``).
+
+All data is dumped (not just for round-trip-mode) with ``.allow_unicode
+= True``
+
+You can of course have multiple YAML instances active at the same
+time, with different load and/or dump behaviour.
+
+Initially only the typical operations are supported, but in principle
+all functionality of the old interface will be available via
+``YAML`` instances (if you are using something that isn't let me know).
+
+If a parse or dump fails, and throws and exception, the state of the
+``YAML()`` instance is not guaranteed to be able to handle further
+processing. You should, at that point to recreate the YAML instance before
+proceeding.
+
+
+Loading
++++++++
+
+Duplicate keys
+^^^^^^^^^^^^^^
+
+In JSON mapping keys should be unique, in YAML they must be unique.
+PyYAML never enforced this although the YAML 1.1 specification already
+required this.
+
+In the new API (starting 0.15.1) duplicate keys in mappings are no longer allowed by
+default. To allow duplicate keys in mappings::
+
+ yaml = ruyaml.YAML()
+ yaml.allow_duplicate_keys = True
+ yaml.load(stream)
+
+In the old API this is a warning starting with 0.15.2 and an error in
+0.16.0.
+
+When a duplicate key is found it and its value are discarded, as should be done
+according to the `YAML 1.1 specification <http://yaml.org/spec/1.1/#id932806>`__.
+
+Dumping a multi-documents YAML stream
++++++++++++++++++++++++++++++++++++++
+
+The "normal" ``dump_all`` expected as first element a list of documents, or
+something else the internals of the method can iterate over. To read
+and write a multi-document you would either make a ``list``::
+
+ yaml = YAML()
+ data = list(yaml.load_all(in_path))
+ # do something on data[0], data[1], etc.
+ yaml.dump_all(data, out_path)
+
+
+or create some function/object that would yield the ``data`` values.
+
+What you now can do is create ``YAML()`` as an context manager. This
+works for output (dumping) only, requires you to specify the output
+(file, buffer, ``Path``) at creation time, and doesn't support
+``transform`` (yet).
+
+::
+
+ with YAML(output=sys.stdout) as yaml:
+ yaml.explicit_start = True
+ for data in yaml.load_all(Path(multi_document_filename)):
+ # do something on data
+ yaml.dump(data)
+
+
+Within the context manager, you cannot use the ``dump()`` with a
+second (stream) argument, nor can you use ``dump_all()``. The
+``dump()`` within the context of the ``YAML()`` automatically creates
+multi-document if called more than once.
+
+To combine multiple YAML documents from multiple files:
+
+::
+
+ list_of_filenames = ['x.yaml', 'y.yaml', ]
+ with YAML(output=sys.stdout) as yaml:
+ yaml.explicit_start = True
+ for path in list_of_filename:
+ with open(path) as fp:
+ yaml.dump(yaml.load(fp))
+
+
+The output will be a valid, uniformly indented YAML file. Doing
+``cat {x,y}.yaml`` might result in a single document if there is not
+document start marker at the beginning of ``y.yaml``
+
+
+
+
+Dumping
++++++++
+
+Controls
+^^^^^^^^
+
+On your ``YAML()`` instance you can set attributes e.g with::
+
+ yaml = YAML(typ='safe', pure=True)
+ yaml.allow_unicode = False
+
+available attributes include:
+
+``unicode_supplementary``
+ Defaults to ``True`` if Python's Unicode size is larger than 2 bytes. Set to ``False`` to
+ enforce output of the form ``\U0001f601`` (ignored if ``allow_unicode`` is ``False``)
+
+Transparent usage of new and old API
+++++++++++++++++++++++++++++++++++++
+
+If you have multiple packages depending on ``ruyaml``, or install
+your utility together with other packages not under your control, then
+fixing your ``install_requires`` might not be so easy.
+
+Depending on your usage you might be able to "version" your usage to
+be compatible with both the old and the new. The following are some
+examples all assuming ``import ruyaml`` somewhere at the top
+of your file and some ``istream`` and ``ostream`` apropriately opened
+for reading resp. writing.
+
+
+Loading and dumping using the ``SafeLoader``::
+
+ yml = ruyaml.YAML(typ='safe', pure=True) # 'safe' load and dump
+ data = yml.load(istream)
+ yml.dump(data, ostream)
+
+Loading with the ``CSafeLoader``, dumping with
+``RoundTripLoader``. You need two ``YAML`` instances, but each of them
+can be re-used::
+
+ yml = ruyaml.YAML(typ='safe')
+ data = yml.load(istream)
+ ymlo = ruyaml.YAML() # or yaml.YAML(typ='rt')

+
++++++++++++++++++++++
+Reason for API change
++++++++++++++++++++++
+
+``ruyaml`` inherited the way of doing things from ``PyYAML``. In
+particular when calling the function ``load()`` or ``dump()``
+temporary instances of ``Loader()`` resp. ``Dumper()`` were
+created that were discarded on termination of the function.
+
+This way of doing things leads to several problems:
+
+- it is virtually impossible to return information to the caller apart from the
+ constructed data structure. E.g. if you would get a YAML document
+ version number from a directive, there is no way to let the caller
+ know apart from handing back special data structures. The same
+ problem exists when trying to do on the fly
+ analysis of a document for indentation width.
+
+- these instances were composites of the various load/dump steps and
+ if you wanted to enhance one of the steps, you needed e.g. subclass
+ the emitter and make a new composite (dumper) as well, providing all
+ of the parameters (i.e. copy paste)
+
+ Alternatives, like making a class that returned a ``Dumper`` when
+ called and sets attributes before doing so, is cumbersome for
+ day-to-day use.
+
+- many routines (like ``add_representer()``) have a direct global
+ impact on all of the following calls to ``dump()`` and those are
+ difficult if not impossible to turn back. This forces the need to
+ subclass ``Loaders`` and ``Dumpers``, a long time problem in PyYAML
+ as some attributes were not ``deep_copied`` although a bug-report
+ (and fix) had been available a long time.
+
+- If you want to set an attribute, e.g. to control whether literal
+ block style scalars are allowed to have trailing spaces on a line
+ instead of being dumped as double quoted scalars, you have to change
+ the ``dump()`` family of routines, all of the ``Dumpers()`` as well
+ as the actual functionality change in ``emitter.Emitter()``. The
+ functionality change takes changing 4 (four!) lines in one file, and being able
+ to enable that another 50+ line changes (non-contiguous) in 3 more files resulting
+ in diff that is far over 200 lines long.
+
+- replacing libyaml with something that doesn't both support ``0o52``
+ and ``052`` for the integer ``42`` (instead of ``52`` as per YAML 1.2)
+ is difficult
+
+
+With ``ruyaml>=0.15.0`` the various steps "know" about the
+``YAML`` instance and can pick up setting, as well as report back
+information via that instance. Representers, etc., are added to a
+reusable instance and different YAML instances can co-exists.
+
+This change eases development and helps prevent regressions.

+***********
+Basic Usage
+***********
+
+You load a YAML document using::
+
+ from ruyaml import YAML
+
+ yaml=YAML(typ='safe') # default, if not specfied, is 'rt' (round-trip)
+ yaml.load(doc)
+
+in this ``doc`` can be a file pointer (i.e. an object that has the
+``.read()`` method, a string or a ``pathlib.Path()``. ``typ='safe'``
+accomplishes the same as what ``safe_load()`` did before: loading of a
+document without resolving unknown tags. Provide ``pure=True`` to
+enforce using the pure Python implementation, otherwise the faster C libraries will be used
+when possible/available but these behave slightly different (and sometimes more like a YAML 1.1 loader).
+
+Dumping works in the same way::
+
+ from ruyaml import YAML
+
+ yaml=YAML()
+ yaml.default_flow_style = False
+ yaml.dump({'a': [1, 2]}, s)
+
+in this ``s`` can be a file pointer (i.e. an object that has the
+``.write()`` method, or a ``pathlib.Path()``. If you want to display
+your output, just stream to ``sys.stdout``.
+
+If you need to transform a string representation of the output provide
+a function that takes a string as input and returns one::
+
+ def tr(s):
+ return s.replace('\n', '<\n') # such output is not valid YAML!
+
+ yaml.dump(data, sys.stdout, transform=tr)
+
+More examples
+=============
+
+Using the C based SafeLoader (at this time is inherited from
+libyaml/PyYAML and e.g. loads ``0o52`` as well as ``052`` load as integer ``42``)::
+
+ from ruyaml import YAML
+
+ yaml=YAML(typ="safe")
+ yaml.load("""a:\n b: 2\n c: 3\n""")
+
+Using the Python based SafeLoader (YAML 1.2 support, ``052`` loads as ``52``)::
+
+ from ruyaml import YAML
+
+ yaml=YAML(typ="safe", pure=True)
+ yaml.load("""a:\n b: 2\n c: 3\n""")

+
+All contributions to ``ruyaml`` are welcome.
+Please post an issue or, if possible, a pull request (PR) on github.
+
+Please don't use issues to post support questions.
+
+TODO:: The maintainers of ruyaml don't have an official support channel yet.
+
+Documentation
+=============
+
+The documentation for ``ruyaml`` is written in the `ReStructured Text
+<http://docutils.sourceforge.net/rst.html>`_ format and follows the `Sphinx
+Document Generator <https://www.sphinx-doc.org/>`_'s conventions.
+
+Code
+====
+
+Code changes are welcome as well, but anything beyond a minor change should be
+tested (``tox``/``pytest``), checked for typing conformance (``mypy``) and pass
+pep8 conformance (``flake8``).
+
+In my experience it is best to use two ``virtualenv`` environments, one with the
+latest Python from the 2.7 series, the other with 3.5 or 3.6. In the
+site-packages directory of each virtualenv make a soft link to the ruyaml
+directory of your (cloned and checked out) copy of the repository. Do not under
+any circumstances run ``pip install -e .`` it will
+not work (at least not until these commands are fixed to support packages with
+namespaces).
+
+You can install ``tox``, ``pytest``, ``mypy`` and ``flake8`` in the Python3
+``virtualenv``, or in a ``virtualenv`` of their own. If all of these commands
+pass without warning/error, you can create your pull-request.
+
+Flake
++++++
+
+The `Flake8 <https://flake8.pycqa.org>`_ configuration is part of ``setup.cfg``::
+
+ [flake8]
+ show-source = True
+ max-line-length = 95
+ ignore = F405
+
+The suppress of F405 is necessary to allow ``from xxx import *``.
+
+Please make sure your checked out source passes ``flake8`` without test (it should).
+Then make your changes pass without any warnings/errors.
+
+Tox/pytest
+++++++++++
+
+Whether you add something or fix some bug with your code changes, first add one
+or more tests that fail in the unmodified source when running ``tox``. Once that
+is in place add your code, which should have as a result that your added test(s)
+no longer fail, and neither should any other existing tests.
+
+Typing/mypy
++++++++++++
+
+You should run ``mypy`` from ``ruyaml``'s source directory::
+
+ mypy --strict --follow-imports silent lib/ruyaml/*.py
+
+This command should give no errors or warnings.
+
+
+Vulnerabilities
+===============
+
+If you find a vulnerability in ``ruyaml`` (e.g. that would show the ``safe``
+and ``rt`` loader are not safe due to a bug in the software)), please contact
+the maintainers directly via email.
+
+After the vulnerability is removed, and affected parties notified to allow them
+to update versions, the vulnerability will be published, and your role in
+finding/resolving this properly attributed.

+************
+Contributing
+************
+
+Any contribution to ``ruamel.yaml`` is welcome, be it in the form of an
+email, a question on stackoverflow (I'll get notified of that when you tag it
+with ``ruamel.yaml``), an issue or pull-request (PR) on sourceforge.
+
+Contributing via stackoverflow is, for most, easiest to make. When I answer your
+question there and the answer warrants an extension to the documentation or
+code, I will include it in a documnetation update and/or future (normally the
+next) release of ``ruamel.yaml``.
+
+Please don't post support questions as an issue on sourceforge.
+
+Documentation
+=============
+
+The documentation for ``ruamel.yaml`` is in YAML, more specifically in `ryd
+<https://pypi.python.org/pypi/ryd>`_ ( /rɑɪt/, pronounced like the verb “writeâ€
+). This is reStructuredText mixed with Python, each in separate YAML documents
+within a single file. If you know a bit of YAML, Python and reStructuredText it
+will be clear how that works.
+
+If you want to contribute to the documentation, you can sent me a clear
+description of the needed changes, e.g. as a unified diff. If the changes
+encompass multiple documents in a ``.ryd`` file, it is best to install ``ryd``
+(use a virtualenv!), clone the ``ruamel.yaml`` repository on sourceforge, edit
+documentation, run ``ryd``::
+
+ ryd --pdf '**/*.ryd'
+
+(quoting might not be necessary depending on your shell), and once the PDF(s)
+look acceptable, submit a pull-request.
+
+``ryd`` will check your file for single backquotes (my most common mistake going
+back and forth between reStructuredText and other mark up).
+
+If you contribute example programs, note that ``ryd`` will automatically run you
+program (so it should be correct) and can include the output of the program in
+the resulting ``.rst`` (and PDF) file.
+
+Code
+====
+
+Code changes are welcome as well, but anything beyond a minor change should be
+tested (``tox``/``pytest``), checked for typing conformance (``mypy``) and pass
+pep8 conformance (``flake8``).
+
+In my experience it is best to use two ``virtualenv`` environments, one with the
+latest Python from the 2.7 series, the other with 3.5 or 3.6. In the
+site-packages directory of each virtualenv make a soft link to the ruamel
+directory of your (cloned and checked out) copy of the repository. Do not under
+any circumstances run ``pip install -e .`` it will
+not work (at least not until these commands are fixed to support packages with
+namespaces).
+
+You can install ``tox``, ``pytest``, ``mypy`` and ``flake8`` in the Python3
+``virtualenv``, or in a ``virtualenv`` of their own. If all of these commands
+pass without warning/error, you can create your pull-request.
+
+Flake
++++++
+
+My ``~/.config/flake8`` file::
+
+ [flake8]
+ show-source = True
+ max-line-length = 95
+ ignore = F405
+
+The suppress of F405 is necessary to allow ``from xxx import *``, which I have
+not removed in all places (yet).
+
+First make sure your checked out source passes ``flake8`` without test (it should).
+Then make your changes pass without any warnings/errors.
+
+Tox/pytest
+++++++++++
+
+Whether you add something or fix some bug with your code changes, first add one
+or more tests that fail in the unmodified source when running ``tox``. Once that
+is in place add your code, which should have as a result that your added test(s)
+no longer fail, and neither should any other existing tests.
+
+Typing/mypy
++++++++++++
+
+If you add methods or functions to ``ruamel.yaml``, you will need to add Python
+2.7 compatible typing information in order for ``mypy`` to pass without error.
+
+I run ``mypy`` from the directory where the (link to) ruamel directory is
+using::
+
+ mypy --py2 --strict --follow-imports silent ruamel/yaml/*.py
+
+This should give no errors or warnings
+
+
+Generated files
+===============
+
+I use a minimal environment when developing, void of most artifacts needed for
+packaging, testing etc. These artifact files are *generated*, just before committing to
+sourceforge and pushing to PyPI, with nuances coming from the ``_package_data``
+information in ``__init__.py``. Including changes in these files will
+automatically be reverted, even assuming your PR is accepted as is.
+
+Consider the following files **read-only** (if you think changes need to made these,
+contact me)::
+
+ tox.ini
+ LICENSE
+ _ryd/conf.py
+ -ryd/Makefile
+
+
+Vulnerabilities
+===============
+
+If you find a vulnerability in ``ruamel.yaml`` (e.g. that would show the ``safe``
+and ``rt`` loader are not safe due to a bug in the software)), please contact me
+directly via email, or by leaving a comment on StackOverflow (below any of my
+posts), without going into the details of the vulnerability. After contact is
+estabilished I will work to eliminate the vulnerability in a timely fashion.
+After the vulnerability is removed, and affected parties notified to allow them
+to update versions, the vulnerability will be published, and your role in
+finding/resolving this properly attributed.

+*******
+Details
+*******
+
+
+
+- support for simple lists as mapping keys by transforming these to tuples
+- ``!!omap`` generates ordereddict (C) on Python 2, collections.OrderedDict
+ on Python 3, and ``!!omap`` is generated for these types.
+- Tests whether the C yaml library is installed as well as the header
+ files. That library doesn't generate CommentTokens, so it cannot be used to
+ do round trip editing on comments. It can be used to speed up normal
+ processing (so you don't need to install ``ruyaml`` and ``PyYaml``).
+ See the section *Optional requirements*.
+- Basic support for multiline strings with preserved newlines and
+ chomping ( '``|``', '``|+``', '``|-``' ). As this subclasses the string type
+ the information is lost on reassignment. (This might be changed
+ in the future so that the preservation/folding/chomping is part of the
+ parent container, like comments).
+- anchors names that are hand-crafted (not of the form``idNNN``) are preserved
+- `merges <http://yaml.org/type/merge.html>`_ in dictionaries are preserved
+- adding/replacing comments on block-style sequences and mappings
+ with smart column positioning
+- collection objects (when read in via RoundTripParser) have an ``lc``
+ property that contains line and column info ``lc.line`` and ``lc.col``.
+ Individual positions for mappings and sequences can also be retrieved
+ (``lc.key('a')``, ``lc.value('a')`` resp. ``lc.item(3)``)
+- preservation of whitelines after block scalars. Contributed by Sam Thursfield.
+
+*In the following examples it is assumed you have done something like:*::
+
+ from ruyaml import YAML
+ yaml = YAML()
+
+*if not explicitly specified.*
+
+Indentation of block sequences
+==============================
+
+Although ruyaml doesn't preserve individual indentations of block sequence
+items, it does properly dump::
+
+ x:
+ - b: 1
+ - 2
+
+back to::
+
+ x:
+ - b: 1
+ - 2
+
+if you specify ``yaml.indent(sequence=4)`` (indentation is counted to the
+beginning of the sequence element).
+
+PyYAML (and older versions of ruyaml) gives you non-indented
+scalars (when specifying default_flow_style=False)::
+
+ x:
+ - b: 1
+ - 2
+
+You can use ``mapping=4`` to also have the mappings values indented.
+The dump also observes an additional ``offset=2`` setting that
+can be used to push the dash inwards, *within the space defined by* ``sequence``.
+
+The above example with the often seen ``yaml.indent(mapping=2, sequence=4, offset=2)``
+indentation::
+
+ x:
+ y:
+ - b: 1
+ - 2
+
+The defaults are as if you specified ``yaml.indent(mapping=2, sequence=2, offset=0)``.
+
+If the ``offset`` equals ``sequence``, there is not enough
+room for the dash and the space that has to follow it. In that case the
+element itself would normally be pushed to the next line (and older versions
+of ruyaml did so). But this is
+prevented from happening. However the ``indent`` level is what is used
+for calculating the cumulative indent for deeper levels and specifying
+``sequence=3`` resp. ``offset=2``, might give correct, but counter
+intuitive results.
+
+**It is best to always have** ``sequence >= offset + 2``
+**but this is not enforced**. Depending on your structure, not following
+this advice **might lead to invalid output**.
+
+Inconsistently indented YAML
+++++++++++++++++++++++++++++
+
+If your input is inconsistently indented, such indentation cannot be preserved.
+The first round-trip will make it consistent/normalize it. Here are some
+inconsistently indented YAML examples.
+
+``b`` indented 3, ``c`` indented 4 positions::
+
+ a:
+ b:
+ c: 1
+
+Top level sequence is indented 2 without offset, the other sequence 4 (with offset 2)::
+
+ - key:
+ - foo
+ - bar
+
+
+Positioning ':' in top level mappings, prefixing ':'
+====================================================
+
+If you want your toplevel mappings to look like::
+
+ library version: 1
+ comment : |
+ this is just a first try
+
+then set ``yaml.top_level_colon_align = True``
+(and ``yaml.indent = 4``). ``True`` causes calculation based on the longest key,
+but you can also explicitly set a number.
+
+If you want an extra space between a mapping key and the colon specify
+``yaml.prefix_colon = ' '``::
+
+ - https://myurl/abc.tar.xz : 23445
+ # ^ extra space here
+ - https://myurl/def.tar.xz : 944
+
+If you combine ``prefix_colon`` with ``top_level_colon_align``, the
+top level mapping doesn't get the extra prefix. If you want that
+anyway, specify ``yaml.top_level_colon_align = 12`` where ``12`` has to be an
+integer that is one more than length of the widest key.
+
+
+Document version support
+++++++++++++++++++++++++
+
+In YAML a document version can be explicitly set by using::
+
+ %YAML 1.x
+
+before the document start (at the top or before a
+``---``). For ``ruyaml`` x has to be 1 or 2. If no explicit
+version is set `version 1.2 <http://www.yaml.org/spec/1.2/spec.html>`_
+is assumed (which has been released in 2009).
+
+The 1.2 version does **not** support:
+
+- sexagesimals like ``12:34:56``
+- octals that start with 0 only: like ``012`` for number 10 (``0o12`` **is**
+ supported by YAML 1.2)
+- Unquoted Yes and On as alternatives for True and No and Off for False.
+
+If you cannot change your YAML files and you need them to load as 1.1
+you can load with ``yaml.version = (1, 1)``,
+or the equivalent (version can be a tuple, list or string) ``yaml.version = "1.1"``
+
+*If you cannot change your code, stick with ruyaml==0.10.23 and let
+me know if it would help to be able to set an environment variable.*
+
+This does not affect dump as ruyaml never emitted sexagesimals, nor
+octal numbers, and emitted booleans always as true resp. false
+
+Round trip including comments
++++++++++++++++++++++++++++++
+
+The major motivation for this fork is the round-trip capability for
+comments. The integration of the sources was just an initial step to
+make this easier.
+
+adding/replacing comments
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Starting with version 0.8, you can add/replace comments on block style
+collections (mappings/sequences resuting in Python dict/list). The basic
+for for this is::
+
+ from __future__ import print_function
+
+ import sys
+ import ruyaml
+
+ yaml = ruyaml.YAML() # defaults to round-trip
+
+ inp = """\
+ abc:
+ - a # comment 1
+ xyz:
+ a: 1 # comment 2
+ b: 2
+ c: 3
+ d: 4
+ e: 5
+ f: 6 # comment 3
+ """
+
+ data = yaml.load(inp)
+ data['abc'].append('b')
+ data['abc'].yaml_add_eol_comment('comment 4', 1) # takes column of comment 1
+ data['xyz'].yaml_add_eol_comment('comment 5', 'c') # takes column of comment 2
+ data['xyz'].yaml_add_eol_comment('comment 6', 'e') # takes column of comment 3
+ data['xyz'].yaml_add_eol_comment('comment 7', 'd', column=20)
+
+ yaml.dump(data, sys.stdout)
+
+Resulting in::
+
+ abc:
+ - a # comment 1
+ - b # comment 4
+ xyz:
+ a: 1 # comment 2
+ b: 2
+ c: 3 # comment 5
+ d: 4 # comment 7
+ e: 5 # comment 6
+ f: 6 # comment 3
+
+If the comment doesn't start with '#', this will be added. The key is
+the element index for list, the actual key for dictionaries. As can be seen
+from the example, the column to choose for a comment is derived
+from the previous, next or preceding comment column (picking the first one
+found).
+
+Config file formats
++++++++++++++++++++
+
+There are only a few configuration file formats that are easily
+readable and editable: JSON, INI/ConfigParser, YAML (XML is to cluttered
+to be called easily readable).
+
+Unfortunately `JSON <http://www.json.org/>`_ doesn't support comments,
+and although there are some solutions with pre-processed filtering of
+comments, there are no libraries that support round trip updating of
+such commented files.
+
+INI files support comments, and the excellent `ConfigObj
+<http://www.voidspace.org.uk/python/configobj.html>`_ library by Foord
+and Larosa even supports round trip editing with comment preservation,
+nesting of sections and limited lists (within a value). Retrieval of
+particular value format is explicit (and extensible).
+
+YAML has basic mapping and sequence structures as well as support for
+ordered mappings and sets. It supports scalars various types
+including dates and datetimes (missing in JSON).
+YAML has comments, but these are normally thrown away.
+
+Block structured YAML is a clean and very human readable
+format. By extending the Python YAML parser to support round trip
+preservation of comments, it makes YAML a very good choice for
+configuration files that are human readable and editable while at
+the same time interpretable and modifiable by a program.
+
+Extending
++++++++++
+
+There are normally six files involved when extending the roundtrip
+capabilities: the reader, parser, composer and constructor to go from YAML to
+Python and the resolver, representer, serializer and emitter to go the other
+way.
+
+Extending involves keeping extra data around for the next process step,
+eventuallly resulting in a different Python object (subclass or alternative),
+that should behave like the original, but on the way from Python to YAML
+generates the original (or at least something much closer).
+
+Smartening
+++++++++++
+
+When you use round-tripping, then the complex data you get are
+already subclasses of the built-in types. So you can patch
+in extra methods or override existing ones. Some methods are already
+included and you can do::
+
+ yaml_str = """\
+ a:
+ - b:
+ c: 42
+ - d:
+ f: 196
+ e:
+ g: 3.14
+ """
+
+
+ data = yaml.load(yaml_str)
+
+ assert data.mlget(['a', 1, 'd', 'f'], list_ok=True) == 196

+**********************
+Dumping Python classes
+**********************
+
+Only ``yaml = YAML(typ='unsafe')`` loads and dumps Python objects out-of-the-box. And
+since it loads **any** Python object, this can be unsafe.
+
+If you have instances of some class(es) that you want to dump or load, it is
+easy to allow the YAML instance to do that explicitly. You can either register the
+class with the ``YAML`` instance or decorate the class.
+
+Registering is done with ``YAML.register_class()``::
+
+ import sys
+ import ruyaml
+
+
+ class User:
+ def __init__(self, name, age):
+ self.name = name
+ self.age = age
+
+
+ yaml = ruyaml.YAML()
+ yaml.register_class(User)
+ yaml.dump([User('Anthon', 18)], sys.stdout)
+
+which gives as output::
+
+ - !User
+ name: Anthon
+ age: 18
+
+The tag ``!User`` originates from the name of the class.
+
+You can specify a different tag by adding the attribute ``yaml_tag``, and
+explicitly specify dump and/or load *classmethods* which have to be called
+``from_yaml`` resp. ``from_yaml``::
+
+ import sys
+ import ruyaml
+
+
+ class User:
+ yaml_tag = u'!user'
+
+ def __init__(self, name, age):
+ self.name = name
+ self.age = age
+
+ @classmethod
+ def to_yaml(cls, representer, node):
+ return representer.represent_scalar(cls.yaml_tag,
+ u'{.name}-{.age}'.format(node, node))
+
+ @classmethod
+ def from_yaml(cls, constructor, node):
+ return cls(*node.value.split('-'))
+
+
+ yaml = ruyaml.YAML()
+ yaml.register_class(User)
+ yaml.dump([User('Anthon', 18)], sys.stdout)
+
+which gives as output::
+
+ - !user Anthon-18
+
+
+When using the decorator, which takes the ``YAML()`` instance as a parameter,
+the ``yaml = YAML()`` line needs to be moved up in the file::
+
+ import sys
+ from ruyaml import YAML, yaml_object
+
+ yaml = YAML()
+

+ @yaml_object(yaml)
+ class User:

+ def from_yaml(cls, constructor, node):
+ return cls(*node.value.split('-'))
+
+
+ yaml.dump([User('Anthon', 18)], sys.stdout)

+
+YAML handcrafted anchors and references as well as key merging
+are preserved. The merged keys can transparently be accessed
+using ``[]`` and ``.get()``::
+
+ from ruyaml import YAML
+

+
+ yaml = YAML()
+ data = yaml.load(inp)
+ assert data[7]['y'] == 2
+
+
+The ``CommentedMap``, which is the ``dict`` like construct one gets when round-trip loading,
+supports insertion of a key into a particular position, while optionally adding a comment::
+
+ import sys
+ from ruyaml import YAML
+
+ yaml_str = """\

+
+ yaml = YAML()
+ data = yaml.load(yaml_str)

+ yaml.dump(data, sys.stdout)
+
+gives::
+
+ first_name: Art
+ last name: Vandelay # new key
+ occupation: Architect # This is an occupation comment
+ about: Art Vandelay is a fictional character that George invents...
+
+Please note that the comment is aligned with that of its neighbour (if available).
+
+The above was inspired by a `question <http://stackoverflow.com/a/36970608/1307905>`_
+posted by *demux* on StackOverflow.
+
+----
+
+By default ``ruyaml`` indents with two positions in block style, for
+both mappings and sequences. For sequences the indent is counted to the
+beginning of the scalar, with the dash taking the first position of the
+indented "space".
+
+You can change this default indentation by e.g. using ``yaml.indent()``::
+
+ import sys
+ from ruyaml import YAML
+
+ d = dict(a=dict(b=2),c=[3, 4])
+ yaml = YAML()
+ yaml.dump(d, sys.stdout)
+ print('0123456789')
+ yaml = YAML()
+ yaml.indent(mapping=4, sequence=6, offset=3)
+ yaml.dump(d, sys.stdout)
+ print('0123456789')
+
+
+giving::
+
+ a:
+ b: 2
+ c:
+ - 3
+ - 4
+ 0123456789
+ a:
+ b: 2
+ c:
+ - 3
+ - 4
+ 0123456789
+
+
+If a block sequence or block mapping is the element of a sequence, the
+are, by default, displayed `compact
+<http://yaml.org/spec/1.2/spec.html#id2797686>`__ notation. This means
+that the dash of the "parent" sequence is on the same line as the
+first element resp. first key/value pair of the child collection.
+
+If you want either or both of these (sequence within sequence, mapping
+within sequence) to begin on the next line use ``yaml.compact()``::
+
+ import sys
+ from ruyaml import YAML
+
+ d = [dict(b=2), [3, 4]]
+ yaml = YAML()
+ yaml.dump(d, sys.stdout)
+ print('='*15)
+ yaml = YAML()

+ - - 3
+ - 4
+ ===============

+three documents::

+
+Output of ``dump()`` as a string
+++++++++++++++++++++++++++++++++
+
+The single most abused "feature" of the old API is not providing the (second)
+stream parameter to one of the ``dump()`` variants, in order to get a monolithic string
+representation of the stream back.
+
+Apart from being memory inefficient and slow, quite often people using this did not
+realise that ``print(round_trip_dump(dict(a=1, b=2)))`` gets you an extra,
+empty, line after ``b: 2``.
+
+The real question is why this functionality, which is seldom really
+necessary, is available in the old API (and in PyYAML) in the first place. One
+explanation you get by looking at what someone would need to do to make this
+available if it weren't there already. Apart from subclassing the ``Serializer``
+and providing a new ``dump`` method, which would ten or so lines, another
+**hundred** lines, essentially the whole ``dumper.py`` file, would need to be
+copied and to make use of this serializer.
+
+The fact is that one should normally be doing ``round_trip_dump(dict(a=1, b=2)),
+sys.stdout)`` and do away with 90% of the cases for returning the string, and
+that all post-processing YAML, before writing to stream, can be handled by using
+the ``transform=`` parameter of dump, being able to handle most of the rest. But
+it is also much easier in the new API to provide that YAML output as a string if
+you really need to have it (or think you do)::
+
+ import sys
+ from ruyaml import YAML
+ from io import StringIO
+
+ class MyYAML(YAML):
+ def dump(self, data, stream=None, **kw):
+ inefficient = False
+ if stream is None:
+ inefficient = True
+ stream = StringIO()
+ YAML.dump(self, data, stream, **kw)
+ if inefficient:
+ return stream.getvalue()
+
+ yaml = MyYAML() # or typ='safe'/'unsafe' etc
+
+with about one tenth of the lines needed for the old interface, you can once more do::
+
+ print(yaml.dump(dict(a=1, b=2)))
+
+instead of::
+
+ yaml.dump((dict(a=1, b=2)), sys.stdout)
+ print() # or sys.stdout.write('\n')

+**********
+Installing
+**********
+
+Make sure you have a recent version of ``pip`` and ``setuptools``
+installed. The later needs environment marker support
+(``setuptools>=20.6.8``) and that is e.g. bundled with Python 3.4.6 but
+not with 3.4.4. It is probably best to do::
+
+ pip install -U pip setuptools wheel
+
+in your environment (``virtualenv``, (Docker) container, etc) before
+installing ``ruyaml``.
+
+``ruyaml`` itself should be installed from PyPI_ using::
+
+ pip install ruyaml
+
+If you want to process jinja2/YAML templates (which are not valid YAML
+with the default jinja2 markers), do ``pip install
+ruyaml[jinja2]`` (you might need to quote the last argument
+because of the ``[]``)
+
+
+There also is a commandline utility ``yaml`` available after installing::
+
+ pip install ruyaml.cmd
+
+that allows for round-trip testing/re-indenting and conversion of YAML
+files (JSON,INI,HTML tables)
+
+Optional requirements
++++++++++++++++++++++
+
+If you have the the header files for your Python executables installed
+then you can use the (non-roundtrip), but faster, C loader and emitter.
+
+On Debian systems you should use::
+
+ sudo apt-get install python3-dev
+
+you can leave out ``python3-dev`` if you don't use python3
+
+For CentOS (7) based systems you should do::
+
+ sudo yum install python-devel

+********
+Overview
+********
+
+``ruyaml`` is a YAML 1.2 loader/dumper package for Python. It is a
+derivative of Kirill Simonov's `PyYAML 3.11
+<https://bitbucket.org/xi/pyyaml>`_.
+
+``ruyaml`` supports `YAML 1.2`_ and has round-trip loaders and dumpers.
+
+- comments
+- block style and key ordering are kept, so you can diff the round-tripped
+ source
+- flow style sequences ( 'a: b, c, d') (based on request and test by
+ Anthony Sottile)
+- anchor names that are hand-crafted (i.e. not of the form``idNNN``)
+- `merges <http://yaml.org/type/merge.html>`_ in dictionaries are preserved
+
+This preservation is normally not broken unless you severely alter
+the structure of a component (delete a key in a dict, remove list entries).
+Reassigning values or replacing list items, etc., is fine.
+
+For the specific 1.2 differences see :ref:`yaml-1-2-support`
+
+Although individual indentation of lines is not preserved, you can specify
+separate indentation levels for mappings and sequences (counting for sequences
+does **not** include the dash for a sequence element) and specific offset of
+block sequence dashes within that indentation.
+
+
+Although ``ruyaml`` still allows most of the PyYAML way of doing
+things, adding features required a different API then the transient
+nature of PyYAML's ``Loader`` and ``Dumper``. Starting with
+``ruyaml`` version 0.15.0 this new API gets introduced. Old ways
+that get in the way will be removed, after first generating warnings
+on use, then generating an error. In general a warning in version 0.N.x will become an
+error in 0.N+1.0
+
+
+Many of the bugs filed against PyYAML, but that were never
+acted upon, have been fixed in ``ruyaml``

+***********************
+Differences with PyYAML
+***********************
+
+.. parsed-literal::
+
+ *If I have seen further, it is by standing on the shoulders of giants*.
+ Isaac Newton (1676)
+
+
+
+``ruyaml`` is a derivative of Kirill Simonov's `PyYAML 3.11
+<https://bitbucket.org/xi/pyyaml>`_ and would not exist without that
+excellent base to start from.
+
+The following a summary of the major differences with PyYAML 3.11
+
+.. _yaml-1-2-support:
+
+Defaulting to YAML 1.2 support
+++++++++++++++++++++++++++++++
+
+PyYAML supports the `YAML 1.1`_ standard, ``ruyaml`` supports
+`YAML 1.2`_ as released in 2009.
+
+- YAML 1.2 dropped support for several features unquoted ``Yes``,
+ ``No``, ``On``, ``Off``
+- YAML 1.2 no longer accepts strings that start with a ``0`` and solely
+ consist of number characters as octal, you need to specify such strings with
+ ``0o[0-7]+`` (zero + lower-case o for octal + one or more octal characters).
+- YAML 1.2 no longer supports `sexagesimals
+ <https://en.wikipedia.org/wiki/Sexagesimal>`_, so the string scalar
+ ``12:34:56`` doesn't need quoting.
+- ``\/`` escape for JSON compatibility
+- correct parsing of floating point scalars with exponentials
+
+unless the YAML document is loaded with an explicit ``version==1.1`` or
+the document starts with::
+
+ % YAML 1.1
+
+, ``ruyaml`` will load the document as version 1.2.
+
+
+Python Compatibility
+++++++++++++++++++++
+
+``ruyaml`` requires Python 3.6 or later.
+
+Fixes
++++++
+
+- ``ruyaml`` follows the ``indent`` keyword argument on scalars
+ when dumping.
+- ``ruyaml`` allows ``:`` in plain scalars, as long as these are not
+ followed by a space (as per the specification)
+
+
+Testing
++++++++
+
+``ruyaml`` is tested using `tox`_ and `py.test`_. In addition to
+new tests, the original PyYAML
+test framework is called from within ``tox`` runs.
+
+Before versions are pushed to PyPI, ``tox`` is invoked, and has to pass, on all
+supported Python versions, on PyPI as well as flake8/pep8
+
+API
++++
+
+Starting with 0.15 the API for using ``ruyaml`` has diverged allowing
+easier addition of new features.

+*************
+Upstrem Merge
+*************
+
+The process to merge ``ruamel.yaml``'s Mercurial repository to ours is
+non-trivial due to non-unique Mergurial-to-git imports and squash merges.
+
+Preparation
+===========
+
+We create a git import of the Upstream repository. Then we add a
+pseudo-merge node to it which represents our version of the code
+at the point where the last merge happened. The commit we want is most
+likely named "Upstream 0.xx.yy".
+
+So, first we get a git copy of an HG clone of the ``ruamel.yaml``
+repository::
+
+ # install Mercurial (depends on your distribution)
+
+ cd /your/src
+ mkdir -p ruyaml/git
+ cd ruyaml/git; git init
+ cd ../
+ hg clone http://hg.code.sf.net/p/ruamel-yaml/code hg
+
+Next we prepare our repository for merging. We need a ``hg-fast-export``
+script::
+
+ cd ..
+ git clone git@github.com:frej/fast-export.git
+
+We use that script to setup our git copy::
+
+ cd ../git
+ ../fast-export/hg-fast-export.sh -r ../hg --ignore-unnamed-heads
+
+Now let's create a third repository for the actual work::
+
+ cd ../
+ git clone git@github.com:pycontribs/ruyaml.git repo
+ cd repo
+ git remote add ../git ruamel
+ git fetch ruamel
+
+Create a branch for merging::
+
+ git checkout -b merge main
+
+This concludes setting things up.
+
+Incremental merge
+=================
+
+First, let's pull the remote changes (if any)::
+
+ cd /your/src/ruyaml/hg
+ hg pull
+ cd ../git
+ ../fast-export/hg-fast-export.sh -r ../hg --ignore-unnamed-heads
+ cd ../repo
+ git fetch --all
+ git checkout merge
+
+Next, we need a pseudo-merge that declares "we have merged all of Upstream
+up to *THAT* into *THIS*", where *THIS* is the latest Merge commit in our
+repository (typically named "Upstream 0.xx.yy") and *THAT* is the
+corresponding commit in the Ruamel tree (it should be tagged 0.xx.yy)::
+
+ git log --date-order --all --oneline
+ git reset --hard THIS
+ git merge -s ours THAT
+
+Now we'll "merge" the current Upstream sources::
+
+ git merge --squash ruamel/main
+
+This will create a heap of conflicts, but no commit yet.
+
+.. note::
+
+ The reason we do a squash-merge here is that otherwise git will
+ un-helpfully upload the complete history of ``ruamel.yaml`` to GitHub.
+ It's already there, of course, but due to the diverging git hashes that
+ doesn't help.
+
+The next step, obviously, is to fix the conflicts. (There will be a bunch.)
+If git complains about a deleted ``__init__.py``, the solution is to ``git
+rm -f __init__.py``.
+
+Then, commit your changes::
+
+ git commit -a -m "Merge Upstream 0.xx.yz"
+ git push -f origin merge
+
+Now check github. If everything is OK, congratulations, otherwise fix and
+push (no need to repeat the ``-f``).
