Dear Hans and Mikael،
Thank you very much for the new upload and the new stuff for tyepsetting maths. I have been playing around with the features presented in the example file sent by Mikael, and I must say, among other things you have implemented, the constructs \bearkhere and \skiphere, and friends, are absolutely great, brilliant and so simple! I wonder why such a simple and elegant solution was not around before…
they were to some extend (in split=text mode) but never advocated but we added some to it as well as made it work with diferent alignments (most noticeably slanted) and number placement (overflow)
As a plain TeX traditionalist I am a little bit sad to let the \over construct be ditched, but my sadness did not last too long.
just think of the side effects: {a}\over{y} + z y and z are combined so one need to add { } {{a}\over{y}} thenm infleuncing styles becomes trickier too; the lot becomes an ord (ok, not in lmtx, where it becomes a fraction atom) and when you compare {{a}\over{y}} \frac{a}{b} you even save two keystrokes -) it's also not easy to control spacing etc because one cannot redefine over; actually fractions uses \U[..over|above|..] which takes two arguments (forward scanning)
It seems that the \choose construct has been ditched but I did not guess what has replaced it (I guess the reason is the same for ditching \over, since the construct used to be ${n \choose k}$ and this is not what one wants to have in a macro).
some of these were just old school simple things but we have better alternatives; and if not: just specify what you need and we will come up with something (configurable) (of course one can just define the old schoose) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
