--- Comment #3 from V Stuart Foote <[email protected]> ---
Again, point is we must continue to produce valid ODF 1.2+ Formulas and working
with OpenType Math tables alone has no UI or input syntax to work with--it
needs inline interpreting of MathML or LaTeX.
Doing HarfBuzz API calls for inline support of OpenType smartfont features and
MathML syntax for rendering formulas in text does not keep us ODF compliant if
we abandon the Math formula editor. LaTex syntax markup is an equally viable
approach (available now with TexMaths extension that requires an external LaTex
instance but embeds formula as PNG or SVG and remains ODF compliant).
So the Math Formula editor would have to be refactored to support OpenType Math
table markup and presumably retain legacy StarMath/Math markup for ODF
compatibility. While doing all that we would take care of (probably required)
the rest of the OpenType smartfont feature support that folks have been asking
for.
And I would hope while doing so we'd implement UI support for inline LaTex
syntax as well, even if using HarfBuzz and not shaping with TeX.
Point being you really can't do anything with HarfBuzz APIs providing OpenType
Math formulas without committing to the LO sm Math Formula editor being
scrapped and starting over. This enhancement is valid, but I don't think anyone
is volunteering to take on the refactoring needed.
