This is likely the side effect of new implementation of glues in LMTX, 
where you can switch the order (\hskip 3pt minus 1pt plus 2pt) and do 
some other tricks. And there are more differences to /The TeXbook /as we 
know it, see luametatex.pdf.
indeed, but the disappearence is somewhat strange .. sode effect of utf 
(second byte is zero) .. fixed in next upload

Hi Hans,

I've found a very interesting bug in lmtx. The following MWE gives the 
expected result in mkiv; in lmtx, one character is missing. Perhaps 
you can figure out what's happening...

[NTG-context] Bug in lmtx bibliography (numerals in entry?)

My bibliography files compiles fine in mkiv, but hangs in lmtx
Here is the error message:

If you say, e.g., '\def\a1{...}', then you must always put '1' after
'\a',
since control sequence names are made up of letters only. The macro here
has not
been followed by the required stuff, so I'm ignoring it.

I am using a custom biblio style, but the command \btxshowentryinline is
not directly called inside.
My ConTeXt version
mtx-context | ConTeXt Process Management 1.04
mtx-context |
mtx-context | main context file:
/usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context | current version: 2020.11.19 11:28
mtx-context | main context file:
/usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkxl
mtx-context | current version: 2020.11.19 11:28



AFAIU, it  means my entry shouldn’t have numbers, right? If so, this may
be a bug, since entry biblio files often have a number inside

Best regards,

Damien Thiriet

Unrelated to tables.

You can reduce xtable and natural table based examples very often to a 
simple \framed because both tables types inherit many features from it.

[NTG-context] Bug in lmtx or wrong setup?

[Jan U. Hasecke]

Hi all,

I encountered a very strange problem.

I want to have section headlines expanding the whole textarea, but the
following copy text of the section shall be typeset in columns.

I have this setup and it works fine.

\setuphead
  [section]
  [
   insidesection=\startcolumns,
   aftersection=\stopcolumns,
  ]


Except for one big problem. ConTeXt (current lmtx from 2020.05.18 16:50)
sometimes has problems to make a page break. And I get the weird result
shown on the attached screenshot.

After the page break the text of the section does not continue. Instead
a number is shown. In the log file I can't find something suspicious.

When I compile the source with current context (2020.01.30 14:13) I get
something like an infinite loop. ConTeXt hangs and has to be killed with
kill pid, Ctrl-C in terminal does not work

So, in my opinion my layout or setup causes a bad situation, where
ConTeXt does not know where to make a page break. While context hangs
and warns me, lmtx runs smoothly but places a number in the text, which
is bad as I might overlook it.

I tried to make mwe but I cannot reproduce the error.

Any ideas to improve my setup? Is this a bug or the intended behaviour?
