what is it
----------
A Python package to parse and build CSS Cascading Style Sheets. (Not a
renderer though!)
about this release
------------------
0.9.6b3 adds a few features and fixes quite a few bugs.
main changes
------------
+ **FEATURE**: Added parsing support and new profile for details
defined in module Fonts http://www.w3.org/TR/css3-fonts/
+ **FEATURE**: Added ``cssutils.parseStyle(cssText,
encoding='utf-8')`` convienience function
+ **FEATURE** (experimental, request from issue #27): Added
``css.CSSStyleDeclaration.children()`` which is a generator yielding any
known children of a declaration including *all* properties, comments or
CSSUnknownRules.
+ FEATURE: ``CSSStyleDeclaration.insertRule`` also accepts a
``CSSRuleList`` now (same as ``CSSStyleSheet`` which does this for some
time now).
+ FEATURE: Added ``CSSStyleDeclaration.keys()`` method which
analoguous to standard dict returns property names which are set in the
declaration.
- **API CHANGE**: Replaced attribute ``css.Property.parentStyle``
with ``css.Property.parent`` (``parentStyle`` is DEPRECATED now).
+ **BUGFIX**: Improved child and parent node referencing.
+ **BUGFIX**: Parsing of CSSValues with unknown function names with
a specific length of 4 or 7 chars were resulting in a SyntaxErr. Also
parsing of comma separated list of CSS FUNCTION values works now.
+ BUGFIX: Fixed validation problems:
- ``font-family: a b`` (values with spaces in names without
being quoted) are parsed now without emitting an ERROR. These are indeed
valid but discouraged and you should use quotes (more than one space is
compacted to a single space anyway so rather complicated without quotes)
- negative lengths for the ``font-size`` property are now
properly reported as ERRORs
- IMPROVEMENT (minor): cssutils sets the HTTP header ``User-Agent``
now when fetching sheets over HTTP (with e.g. ``cssutils.parseUrl``).
- *FEATURE* (experimental): Added support to at least parse sheets
with Microsoft only property values for ``filter`` which start with
``progid:DXImageTransform.Microsoft.[...](``. To enable these you need
to set::
>>> from cssutils import settings
>>> settings.set('DXImageTransform.Microsoft', True)
>>> cssutils.ser.prefs.useMinified()
>>> text = 'a {filter:
progid:DXImageTransform.Microsoft.BasicImage( rotation = 90 )}'
>>> print cssutils.parseString(text).cssText
a{filter:progid:DXImageTransform.Microsoft.BasicImage(rotation=90)}
>>>
This currently is a **major hack** but if you like to minimize
sheets in the wild which use this kind of CSS cssutils at least can
parse and reserialize them.
