\beginsection On the future of \TeX
Working on Malayalam-\TeX, I met with more and more limitations of
\TeX, which needed ad-hoc solutions, that will not win an elegance
price. It made me dream of a future \TeX-like system, that would
incorporate all scripts in a more elegant way. Several people have
made suggestions on the future of \TeX, but most of them, again,
focussed on the Western languages. I think a transistion to the
emerging 16-bit Unicode (ISO 10646) standard will be the most natural
next step.
\TeX\ was orignally designed for two `scripts', English and
Mathematics, and it does a very good job of typesetting both of them,
but one gets in problems when one tries to typeset another script with
it, for example Malayalam, or one of the various other scripts in use
for writing the spoken languages of the world, or to name the most
difficult of all, typesetting music. A future-\TeX\ should be build up
in some modular manner, so that other scripts can be added more
easily.
Apart from being a typesetting system, \TeX\ is a fullfledged
programming language, but a horrible ackward one. As Frank Mittelbach,
suggested, it would be nice to replace it with a more conventional
one, although his suggestion to use lisp fills me with new horrors. I
think a more modern functional language like miranda would be a much
candidate. A functional language with some very basic functions needed
for typesetting would be a good kernel in my eyes. All logic needed
for typesetting a script could then be coded in the language itself,
instead of being hardwired into the system.
Adding a new script would then be as easy as designing a font for the
script (A difficult enough task in itself) and writing the logic for
composing the script from a character-stream, which then could be
loaded into the system.
An anochronism that has annoyed me more and more when I started making
several variants and sizes of my font is the use of bitmaps, with took
up more and more space on my harddisk.
I would propose to join the powers of \TeX\ and \MF into one program,
that use the speak the same language, so that one can have direct
access to character-programs, to create the letter in the size and
style wanted at the a certain moment.
