Honestly, I don't know. At least not w/o reading findNextLineBreak. It's
not a part of the code I've had to look into in great detail yet.
You can ask on #webkit, but it's better if you just read the source
yourself:

Ok Eric but Can you also tell me in brief how it decides to go to the next
line? Does the function uses glyph metrics to for example calculate the
width of each character and the decides how many will reach the limit? Or
there so kind of approximation? Also if it do use glyph metrics can you
guide to the variable to pointer to where it gets its needed info?
I'm going through the function but I'm at beginning of the road.

Line breaking is done in findNextLineBreak in RenderBlockLineLayout.
There is a talk on Youtube from me which touches on some of this.
The RenderTexts get broken into lines, then the bidi algorithm is run and
then line boxes are created. The text contents of the line boxes are passed
individually to the paint functions at paint time.

Hi
I'm working on text rendering of WebKit. I tried to find my path through it
and I was a bit successful but I'm wondering in a gtk build when there is a
large paragraph of text to be shown on screen where does the length of each
line decided? I know that to show text a drawText function in the Font.cpp
is called but the issue is it gets a string for each line, my question is
for a large paragraph where does the code cuts the text in lines and decides
the length and prepare it for drawText function?
Thanks
