new uplaod

new uplaod

[Hans Hagen via ntg-context]

Hi,

I uploaded a new lmtx. Again some updated math of which details will be 
revealed later. Apart from some details we added suport for fourier 
notations. There are no high level definitions yet as we have to invent 
names but this is how it works (private unicode slots might change):

\setupbodyfont[pagella]

\starttext

\setupmathdelimited
   [topoffset=.2\exheight]

\definemathdelimited
   [fourier]
   [rule=no,
    left=\zerocount,
    right="FE944]

\definemathdelimited
   [courier]
   [rule=no,
    left=\zerocount,
    right="FE946]

\definemathdelimited
   [xourier]
   [rule=no,
    left=\zerocount,
    right="FE948]

$ \fourier{(z+1)} $

$ \fourier{(z+1)} + \sqrt[2]{1}$

$ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $

$ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + 
\xourier{\left(z+\frac12\right)} $

$ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + 
\xourier{(z+\frac12)} $

$ \widehat{x^2 + 2x + 2} $

\stoptext

This example also shows a new \autofences feature and widehats 
(widetilde and widecheck also work that way) that overcome limitations 
in fonts, so

\def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + 
#1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par}
\CrappyHack\widehat
\CrappyHack\widetilde
\CrappyHack\wideacute
\CrappyHack\widecheck

will work. For thise in finance we now have

$ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 
1} $

these are basically radicals (like sqrt) with two sided symbols.

Hi Hans,

Will \mvert and \mid also be included in the \autofence logic? It would be
quite useful.

i prototyped it but the chairman of the CMS has to check it before we 
decide to enable it

one complication is that

$ \autofences x | \frac{a}{x}$

$ \autofences ( \frac{a}{x} + b | x )$

should also work (lone middles)

we don't have \mvert so i'll add that ... in a next upload you can do 
the attached (kind of experimental as Mikael and I need to review this 
which we will do next week)

Hi Hans,

Thanks a lot for the example. It works great in most cases, however what I
stumbled upon is with the interval notation, in particular the following
cases arise:
- closed interval: easy, since the delimiters are [... ; ... ]
- open interval: not easy, since the delimiters are ]... ; ... [ (or with a
parenthesis as in the US, but there it works)
- semi open interval: not easy, since the delimiters are either [... ; ...
[ or ]... ; ...] (or in the US [...; ...) or (... ; ...])

I guess there is a need for a special definition for these. Maybe they're
already in the works...

By the way, if I define in the preamble \autofences, is there a command to
disable it locally? Would be very helpful to deal with the above situations.

Best regards,
Alex

In case someone else stumbles upon this issue, the following code works.

new uplaod

[Hans Hagen via ntg-context]

Hi,

a new lmtx upload

- crash with bottom floats probably solved: had to do with tricky 
interaction between engine insert handling and callback interference (as 
well as some assumptions in the engine dating that relate to the fact 
that tex was never written to be opened up this way)

- crash due to math initialization: this related to a new mechanism wrt 
math parameters that Mikael and I are playing with .. think of this:

\newmuskip    \mymuskipA
\mugluespecdef\mymuskipB 0mu

\inherited\Umathfracfracspacing\textstyle\mymuskipA
\inherited\Umathradradspacing  \textstyle\mymuskipB

\startTEXpage[offset=3bp]
                   \mymuskipA 10mu
     \mugluespecdef\mymuskipB 10mu
     $\mathfrac{x}\mathfrac{x}$\par
     $\mathrad {x}\mathrad {x}$\par
                   \mymuskipA 20mu
     \mugluespecdef\mymuskipB 20mu
     $\mathfrac{x}\mathfrac{x}$\par
     $\mathrad {x}\mathrad {x}$\par
                   \mymuskipA 30mu
     \mugluespecdef\mymuskipB 30mu
     $\mathfrac{x}\mathfrac{x}$\par
     $\mathrad {x}\mathrad {x}$\par
                   \mymuskipA 30mu plus 10mu minus 10mu
     \mugluespecdef\mymuskipB 30mu plus 10mu minus 10mu
     $\mathfrac{x}\mathfrac{x}$\par
     $\mathrad {x}\mathrad {x}$\par
\stopTEXpage

tex has a few abstractions (thinmuskip etc) than basically postpone a 
setting so that they can be adapted by setting these 'special - internal 
in luametatex speak - mu glue registers' but is is being generalized so 
that we can group math (integer, dimension, glue) parameters by binding 
them to registers and constants ... that way we can do simple and 
efficient switches to different spacing ... just that you know
