although I haven't participated explicitly to abiword's development so
far, I was in touch with Martin Sevior for adding math support
(rendering/editing) within abiword. The idea was to create a bonobo
component around my gtkmathview widget for mathml
(http://helm.cs.unibo.it/mml-widget) which could be embedded in abiword
documents (and hopefully elsewhere). The basic prerequisite to start
investigating this was having the widget understand "editing", which is
what I've been working on in the last few months. I can say I'm pretty
close to releasing the first version with editing support within weeks.
When I say "editing" I mean that the widget is able to react efficiently
to changes in the underlying (DOM) document, so that as you change the
document (in an unspecified way, from the widget's point of view), the
rendering is updated automatically. Plain rendering has been working
nicely, even on large MathML documents (up to a few megs of XML markup),
for a couple of years by now.
As for the palette-driven math editors that we all know (and that seem
to proliferate, see also the mathml editor in mozilla), I'm not very
keen on them, although there can be no alternative in some
circumstances. BUT, I'm also working on an editor based on the following
idea: you type in TeX/LaTeX markup, the markup is converted on-the-fly
into MathML and the MathML is displayed by gtkmathview. With a suitable
architecture the whole process is not as heavy as it may sound, and the
first results I've got are impressive (according to people who assisted
a demo). This editor too is going to be available in the next future.
Basically it follows what TeXmacs already does, but it differs in that
it accepts _exactly_ the TeX syntax and it is modular and extensible
(MathML is generated via XSLT stylesheets).
Even though I have no control over what other people are doing, there
are a couple of guys who are looking right now at a Windows port for
gtkmathview and also at the creation of a bonobo component around it. I
believe these are two important prerequisites for considering abiword +
gtkmathview pluggability.
