types if their checks pass (and ``stringify`` is set).

If ``preserve_errors`` is ``True`` (``False`` is default) then instead
1995
of a marking a fail with a ``False``, it will preserve the actual
1996
exception object. This can contain info about the reason for failure.
1997
For example the ``VdtValueTooSmallError`` indeicates that the value

1999
still be marked as ``False``.

def flatten_errors(cfg, res, levels=None, results=None):
2530
An example function that will turn a nested dictionary of results
2531
(as returned by ``ConfigObj.validate``) into a flat list.
2533
``cfg`` is the ConfigObj instance being checked, ``res`` is the results
2534
dictionary returned by ``validate``.
2536
(This is a recursive function, so you shouldn't use the ``levels`` or
2537
``results`` arguments - they are used by the function.
2539
Returns a list of keys that failed. Each member of the list is a tuple :
2542
([list of sections...], key, result)
2544
If ``validate`` was called with ``preserve_errors=False`` (the default)
2545
then ``result`` will always be ``False``.
2547
*list of sections* is a flattened list of sections that the key was found
2550
If the section was missing then key will be ``None``.
2552
If the value (or section) was missing then ``result`` will be ``False``.
2554
If ``validate`` was called with ``preserve_errors=True`` and a value
2555
was present, but failed the check, then ``result`` will be the exception
2556
object returned. You can use this as a string that describes the failure.
2558
For example *The value "3" is of the wrong type*.

With list values off, ConfigObj can incorrectly unquote values. (This makes
2239
it impossible to use listquote to handle your list values for you - for
2240
nested lists. Not handling quotes at all would be better for this)
2953
Better support for configuration from multiple files, including tracking
2954
*where* the original file came from and writing changes to the correct
2958
Make ``newline`` an option (as well as an attribute) ?
2960
``UTF16`` encoded files, when returned as a list of lines, will have the
2961
BOM at the start of every line. Should this be removed from all but the
2964
Option to set warning type for unicode decode ? (Defaults to strict).
2245
2966
A method to optionally remove uniform indentation from multiline values.
2246
2967
(do as an example of using ``walk`` - along with string-escape)
2969
Should the results dictionary from validate be an ordered dictionary if
2970
`odict <http://www.voidspace.org.uk/python/odict.html>`_ is available ?

Implement a better ``__repr__`` ? (``ConfigObj({})``)

INCOMPATIBLE CHANGES
2249
2978
====================
3110
Removed ``BOM_UTF8`` from ``__all__``.
3112
The ``BOM`` attribute has become a boolean. (Defaults to ``False``.) It is
3113
*only* ``True`` for the ``UTF16`` encoding.
3115
File like objects no longer need a ``seek`` attribute.
3117
ConfigObj no longer keeps a reference to file like objects. Instead the
3118
``write`` method takes a file like object as an optional argument. (Which
3119
will be used in preference of the ``filename`` attribute if htat exists as
3122
Full unicode support added. New options/attributes ``encoding``,
3123
``default_encoding``.
3125
utf16 files decoded to unicode.
3127
If ``BOM`` is ``True``, but no encoding specified, then the utf8 BOM is
3128
written out at the start of the file. (It will normally only be ``True`` if
3129
the utf8 BOM was found when the file was read.)
3131
File paths are *not* converted to absolute paths, relative paths will
3132
remain relative as the ``filename`` attribute.
3134
Fixed bug where ``final_comment`` wasn't returned if ``write`` is returning
3140
Added ``True``, ``False``, and ``enumerate`` if they are not defined.
3141
(``True`` and ``False`` are needed for *early* versions of Python 2.2,
3142
``enumerate`` is needed for all versions ofPython 2.2)
3144
Deprecated ``istrue``, replaced it with ``as_bool``.
3146
Added ``as_int`` and ``as_float``.
3148
utf8 and utf16 BOM handled in an endian agnostic way.
3153
Validation no longer done on the 'DEFAULT' section (only in the root
3154
level). This allows interpolation in configspecs.
3156
Change in validation syntax implemented in validate 0.2.1
3163
Added ``merge``, a recursive update.
3165
Added ``preserve_errors`` to ``validate`` and the ``flatten_errors``
3168
Thanks to Matthew Brett for suggestions and helping me iron out bugs.
3170
Fixed bug where a config file is *all* comment, the comment will now be
3171
``initial_comment`` rather than ``final_comment``.
3176
Fixed bug in ``create_empty``. Thanks to Paul Jimenez for the report.
3181
Fixed bug in ``Section.walk`` when transforming names as well as values.
3183
Added the ``istrue`` method. (Fetches the boolean equivalent of a string
3186
Fixed ``list_values=False`` - they are now only quoted/unquoted if they
3187
are multiline values.
3189
List values are written as ``item, item`` rather than ``item,item``.
2381
3196
Fixed typo in ``write`` method. (Testing for the wrong value when resetting
2382
3197
``interpolation``).
