- Ruby does not preserve expansion opportunities from enclosing context
- https://bugs.webkit.org/show_bug.cgi?id=139618
-
- Reviewed by David Hyatt.
-
- There is currently no sharing of expansion opportunity information between
- ruby bases and the text surrounding the ruby. This patch adds a bit on
- RenderText, m_contentIsKnownToFollow, which affects how expansion
- opportunities are handled at paint-time, as well as a bit on RenderRubyBase,
- m_isAfterExpansion, which affects how expansions are calculated when laying
- out a line. This patch also adds a field to RenderRubyBase which represents
- the base's starting position within a ruby. This field is necessary because
- an expansion from a line might occur at the very beginning of a ruby base,
- so we have to remember some state from expansion time to RenderRubyBase
- layout time.
-
- Added more tests to fast/ruby/ruby-justification.html.
-
- * rendering/InlineBox.h:
- (WebCore::InlineBox::setExpansionWithoutGrowing):
- (WebCore::InlineBox::expansion):
- * rendering/InlineFlowBox.cpp:
- (WebCore::InlineFlowBox::removeChild): Keep the bit on InlineTextBox up to
- date.
- (WebCore::InlineFlowBox::placeBoxRangeInInlineDirection): Set expansion
- information in InlineFlowBoxes so the total expansion for a whole line
- is held in the RootInlineBox's expansion.
- * rendering/InlineTextBox.h:
- (WebCore::InlineTextBox::expansionBehavior):
- * rendering/RenderBlockFlow.h:
- * rendering/RenderBlockLineLayout.cpp:
- (WebCore::RenderBlockFlow::updateRubyForJustifiedText):
- updateRubyForJustifiedText() had a bunch of problems with it. First of all,
- it didn't actually set the InlineBoxes as dirty, so the second layout pass
- sometimes wouldn't perform any updates. Secondarily, it didn't take
- overhangs into account. Thirdly, it didn't mark the ruby base and text as
- needing layout so that subsequent layouts would actually traverse into them.
- (WebCore::RenderBlockFlow::computeExpansionForJustifiedText):
- (WebCore::RenderBlockFlow::computeInlineDirectionPositionsForSegment):
- This nested if triangle is super nasty, but I'm not sure of a better way to
- write it.
- (WebCore::updateRubyForJustifiedText): Deleted.
- (WebCore::computeExpansionForJustifiedText): Deleted.
- * rendering/RenderRubyBase.cpp:
- (WebCore::RenderRubyBase::RenderRubyBase):
- (WebCore::RenderRubyBase::adjustInlineDirectionLineBounds):
- * rendering/RenderRubyBase.h:
- * rendering/RenderRubyRun.cpp:
