Hi, Adam, I have recently worked on several issues about line breaking. Glad to hear your plans. Actually I'm a bit tired of waiting for responses about the issues (and about some other 'old' layout bugs). Your involvement would greatly help resolve them.
What I have done on these issues are as follows. Hope these information will be useful for you. 1) https://bugs.webkit.org/show_bug.cgi?id=37698: I wrote a test to generate line breaking matrix for each browser. However, the test can't reflect some stateful behaviors of some browsers. The patch extends the original ASCII line breaking rule dealing with line-breaking only after '?' and hyphen to a full line breaking matrix to allow line breaking after ')', '}' and ']'. The patch has been landed. 2) https://bugs.webkit.org/show_bug.cgi?id=20677: I created a simple patch that disallows line-breaking between a digit and a hyphen. Waiting for review and/or responses. 3) https://bugs.webkit.org/show_bug.cgi?id=37543 I think fixing 2) and 3) might need a refactory to the line breaking code. The break_lines.cpp looks weird because of its non-standard filename and because it inserts a pure C functional layer into OO code. It causes difficulties to implement a stateful line-breaking algorithm. For ICU implementation, break_lines.cpp also causes many unnecessary ubrk_setText() calls. My thought is to move the logic in break_lines.cpp down into the implementations of TextBreakIterator, so that the interface could be stateful. Please let me know if I could be any help.
