Need some hints to fix my standalon installation

Need some hints to fix my standalon installation

[Christoph Hintermüller via ntg-context]

[-- Attachment #1: Type: text/plain, Size: 854 bytes --]

Hi
Have updated my standalone installation from one of the 2020 releases
to the latest one running

./first-setup.sh --context=latest --modules=all

Now i see the strange behavior that fraction in second equation is not
typeset instead typesetting math aborts after typesetting the upper
part of the fraction. A short example showing this is attached (pdf,
tex, and log)

Therefore i have the following questions
 - would it help to sacrifice the updated standalone installation and
   do a fresh install
 - What else i would have to check and probably fix to make the math 
   working as expected
 - any thing else to change

Hi Christoph,

sorry for the obvious suggestion «post facto»: never update ConTeXt
without a backup first.

I don’t think it would work, since it only works with LuaMetaTeX.

I got the same results (in Windows [because I cannot make it work in
Linux]) with LuaTeX 1.15 (the one that comes with ConTeXt LMTX).

My suggestion would be a fresh install (in a different directory, no
need to remove anything) of ConTeXt LMTX.

Math is being improved in ConTeXt these days. It might be a bug.

I wonder whether Mikael or Hans could review your issue.

Just in case it might help,

Pablo

The strange thing with fractions seems to be due to the parameter
FractionNumeratorDisplayStyleShiftUp in lm.lfg. If you always set it
to 600, it seems to work also for luatex. (This will be fixed.)

Another thing: Instead of using \over, I suggest that you use \frac
(less surprises). Something like:

\starttext
\startformula
        a=b + 1
\stopformula

\startformula
        a = \frac{ b + \mu }{ c }
\stopformula

\startformula
        a = \frac{\frac{ b + \mu }{ c } + e}{ d + i }
\stopformula
\stoptext

Thank you very much for the hints. \frac didn't help either even after
moving broken installation aside and doing a fresh install with
 
sh ./first-setup.sh --modules=all --context=latest


Results still similar see attached.

We had to adapt the lfg file for lm (other fonts are ok) so i'll make an 
update.

If you're in a hurry, in lm.lfg:

         parameters = {
             FractionNumeratorDisplayStyleShiftUp = 600, -- used to be a 
function
             NoLimitSupFactor                     =   0,
             NoLimitSubFactor                     = 900,
          -- AccentBaseHeight                     =   0,
             AccentBaseDepth                      =  50,
         },

can be adapted.

Hans

Hi Christoph,

to check when there is a new release I use:

curl -I https://lmtx.pragma-ade.com/install-lmtx/texmf-context.zip 2>&1
| grep -i Last-Modified

Just in case it might help you,

Pablo

Hi,

I have an rsync cron job running each hour that alerts me if there is a new upload. If nobody objects, I could direct the cron notification email to the list?
