Didn't touch the -webkit-wrap-shape: path() because that will make the patch too big. For path() I can modify the tokenizer to catch the path(....) similar to how uri() works and let the existing SVG path data parser produce the shape. I will keep that in a different patch.

Comment 5 2011-06-06 05:49:40 PDT

The patch is obsolete because it used ENABLE(EXCLUSIONS) but the flag was renamed to ENABLE(CSS_EXCLUSIONS). I've also added https://bugs.webkit.org/show_bug.cgi?id=62114 because I need to add new optional properties in CSSPropertyNames.in that need to be defined only when ENABLE_CSS_EXCLUSIONS flag is used. I might need to update the patch depending on the resolution on that bug. I will update the patch after bug #62114 is closed.

For one thing, this will make transitions/animations difficult to implement. So you should probably have a CSSShapeValue distinct from your RenderStyle shape representation.

Thank you for the review! > This would be better as a pure JS test. See LayoutTests/fast/css/parsing* for examples. Note that there's a script to generate the HTML file from the script-tests/foo.js file: ./Tools/Scripts/make-script-test-wrappers I will use that instead and add an updated patch. > Shape feel slightly too generic for the name of this file. CSShape? ExclusionShape? ExclusionShapes: The shapes are not used only for exclusions. It will also be used to define the interior of a box. CSSShapes: It contains 3 "S" letters inside, little hard to type/read. I think I will use "CSSWrapShapes" because the currently the wrap-shape is the only property using it. I will also update the name of the classes. > It's going to be easy to loose track of this. You should either fix it now, or file a bug and reference the bug in the comment. I will add a bug for that. > Shouldn't a shape change be a layout change? The current spec is being reworked to remove dependencies between exclusions and affected content. There's a proposal to use floats instead. In that case, wrap-shape should actually relayout the parent container. For sure, I will have to revisit this code, but for now I've added that in order to avoid having diff(x, y) == None where wrap-shapes actually differ. > We don't usually have RenderStyle things reference CSSValue things directly. For one thing, this will make transitions/animations difficult to implement. > So you should probably have a CSSShapeValue distinct from your RenderStyle shape representation. I followed the implementation for Rect and Counter in CSSPrimitiveValue, so Shape is not inheriting from CSSValue. It is wrapped in the CSSPrimitiveValue class. Isn't that similar to having CSSShapeValue?

Comment 11 2011-06-21 07:52:45 PDT

Created attachment 97986 [details] Patch - Created pure JS test - Renamed Shape.h/cpp to CSSWrapShapes.h/cpp - Renamed class Shape to CSSWrapShape. Also its friends are renamed to CSSWrapShapeRect, CSSWrapShapeCircle, CSSWrapShapeEllipse and CSSWrapShapePolygon - Uses the pre-processing of the CSSPropertyNames.in and CSSValueKeywords.in. That is added in https://bugs.webkit.org/show_bug.cgi?id=62114 which was reviewed, but is not yet in trunk, so this is why the build-bot should have failed. Because the CSSWrapShapePolygon needs evenodd and nonzero, I moved that enum from Path.h to its own WindRule.h file. Evenodd and nonzero are keywords used by both SVG and Wrap Shapes. Because of that I had to add that #if in SVGCSSValueKeywords.in

Comment 18 2011-07-01 15:46:55 PDT

Created attachment 99531 [details] Patch - fixed variables naming Renamed "a" to "argument" and "i" to "argumentNumber". Also changed if's to switches. It removes the need to write if (!argumentNumber) instead of if (argumentNumber == 0). Also there's is no way to get more arguments then we account for in the switch. That's because it checks for the size of the arguments list. Also added an assert to check that.

I've already added #if ENABLE(CSS_EXCLUSIONS) just after the #define CSSWrapShapes_h > Also, we normally try to do a patch per bug so can you upload the new patch to a new bug? Created new bug and added new patch and updated just the changelog file. Can you please review https://bugs.webkit.org/show_bug.cgi?id=64464 ?
