-Is there any way that I can apply pure raw lfbd/rtbd values to
protrusion with no other protrusion calculation at all in opbd?
you can create your own vectors if you want
My own vectors wouldn’t solve the issue, because the variable would be:
lfbd(Ὧ) = glyph.width(Ω) - glyph.width(Ὧ)
I need to place glyphs accurately, not characters. Character dimensions
wouldn’t help to get hanging diacritics.
well, these dimensions are available so one could use them in
constructing additional lfbd feature specifications (add f eatures
runtime)
-In order to avoid editing all the Greek fonts to get hanging
diacritics: is there any way to replicate the lfbd feature with
"fonts.handlers.otf.addfeature"?
probably with some lua magic one can do a lot but these are typical
things i do when i need them (also because one needs to check the whole
of unicode and cook up categories, this kind of stuff is: do it all
robust and well or don't do it; also one doesn't know how consistent
font designs are)
The variable is so simple that the glyph with diacritical marks should
be placed in the beginning of the line as it had no such marks.
the mechanism is more complex: the linebreak algorithm has to take this
into account (both ends of a potential line) and also look over e.g. par
starts and so
