about this release
------------------
0.9.8a1 is an early alpha release. Please note the *major* changes in
the css value API.
main changes
------------
+ **API CHANGE (major)**
replace CSSValue with PropertyValue, Value and other classes.
NEW CLASSES:
:class:`cssutils.css.PropertyValue`
replaces CSSValue and CSSValueList
- is iterable (iterates over all single Value objects which
in soruce CSS might be separated by "," "/" or " "
- a comma separated list of IDENT values is no longer
handled as a single String (e.g. ``Arial, sans-serif``)
:class:`cssutils.css.Value`
replaces CSSPrimitiveValue with separate ``value`` and
``type`` info (value is typed, so e.g. string for e.g. STRING, IDENT or
URI values, int or float) and is base class for more specific values like:
:class:`cssutils.css.URIValue`
replaces CSSPrimitiveValue, additional attribute ``uri``
:class:`cssutils.css.DimensionValue`
replaces CSSPrimitiveValue, additional attribute ``dimension``
:class:`cssutils.css.ColorValue`
replaces CSSPrimitiveValue, additional attribute ``red``,
``green``, ``blue`` and ``alpha``
**TODO: Not yet complete, only rgb, rgba, hsl, hsla and has
values use this object and color and alpha information no done yet!**
:class:`cssutils.css.CSSFunction`
replaces CSSPrimitiveValue function, not complete yet
also renamed ``ExpressionValue`` to
:class:`cssutils.css.MSValue` with new API
- IMPROVEMENT/CHANGE: Validation of color values is tighter now. Values
like ``hsl(1, 2, 3)`` do not validate as it must be ``hsl(1, 2%, 3%)``.
This mostly effects HSL/A and RGB/A notation.
- **IMPROVEMENT**: New Value parsing and API accelerate parsing of style
declarations which take about 20-30% less time now. Of course this
depends on the complexity of your styles.
+ BUGFIX: fixes issue #41, #42, #45, #46
PropertyValue.value returns value without any comments now, else
use PropertyValue.cssText
- FEATURE: ``cssutils.replaceUrls()`` accepts as first argument a
`cssutils.css.CSSStyleSheet` but now also a
:class:`cssutils.css.CSSStyle
