This works nicely. Thanks.
I'll also go back to the mathalign document and try to update it for the
current LMTX to catch other regressions which might have happened.

[NTG-context] blank pages bug [pagecolumns]
Hi there,
I noticed a bug when using pagecolumns. If there is a title on the right column,
a blank page gets added at the end of the document. For example
\starttext
\startpagecolumns[n=2]
\title{lorem}
\title{ipsum}
\stoppagecolumns
\stoptext
gives an additional blank page. If you remove the second title (ipsum) then not.
Best regards,
Johann

[NTG-context] About \includeMPgraphic and local presets
Hi, list!
I've read elsewhere \MPrawvar allows a preset to be applied outside
\start...\stopuseMPgraphic.
\startuseMPgraphic{hi}
draw fullcircle scaled \MPrawvar{hi}{u};
\stopuseMPgraphic
\setupMPvariables[hi][u=1cm]
\startMPcode
\includeMPgraphic{hi}
\stopMPcode
However, \includeMPgraphic{...} only accepts one argument. I've come up
with a somewhat ugly solution to pass a different value:
\begingroup %\start
\setupMPvariables[hi][u=2cm]
\startMPcode
\includeMPgraphic{hi}
\stopMPcode
\endgroup %\stop
%Outside \MPrawvar{hi}{u} will be 1cm
What should I do to keep redefinitions local or pass settings only for
certain instances of \IncludeMPgraphic{...}? Is there a better solution?
Thank you in advance.
Best regards and best wishes for this New Year!
Jairo

Re: [NTG-context] xrightarrow specific size issue
Hi Aditya,
I know the syntax, my problem is about the options for the length of the arrow.
For example
\xrightarrow[big]{abc}
gives a longer arrow than
\xrightarrow{abc}
According to different manuals also specific lengths should be possible. But
they don't work. I think it's a bug. (because the example from a documentation
doesn't work)
Best regards,
Johann

Re: [NTG-context] prevent error page
On 12/31/2020 8:31 PM, Johann Birnick wrote: Hi there, in my setup I constantly have a pdf viewer open showing the output of context. When I recompile the viewer updates. Now if there is an error, the document fails to compile, of course. Previously the pdf file just remainded untouched, nice. But now with LMTX, the pdf will be overwritten with a pdf just saying "error". This makes my pdf viewer crash! I can't work like this. So how to prevent this "error" page and just let context remain the pdf untouched if there is an error? Actually the remaining file is not untouched when there is an error halfway, so maybe your viewer didn't do anything when the xref etc was missing and fonts were unresolved ... all depends on the viewer i guess (after a pdf update the viewer has to reread the xref at least and then all objects it has cached). Long ago I played with a temp file and renaming but that also was not stable (at least not here).
