Re: [NTG-context] error in LMTX?

[Hans van der Meer]

Found the origin of the curious error message containing my name.
Comes from the inclusion of a file named type-loc.mkiv residing in a directory 
~/TeX/texmf/tex/context/user/ and containing:

\endinput

Op NTG ConTeXt nieuwsgroep, antwoord van Hans Hagen.

How this got included? I have no idea.
But removing it did not make a difference, even after calling mtxrun --generate.

I did some more research and as a result now wonder what is happening.

The error occurred in this piece of code of mine:

\tabskip=1em\halign{%
\alignmark\hfil\aligntab\alignmark\hfil\cr
fontclass\aligntab\fontclass\cr
Regular\aligntab\truefontname{Regular}\cr
}

\aligntab and \alignmark were advertised as LuaTeX equivalents for & and # 
respectively.

Then I took the following example from Victor Eijkhout's book "TeX by Topic", 
page 197, last example.
That surely should work, was the idea.

\starttext
\halign{a###\cr 1&2\cr 1\cr}
\stoptext

However this fails! How can such a basic example in pure TeX fail? I wonder and 
am curious what is happening here.

This is LuaMetaTeX, Version 2.00.0 
tex error   > tex error on line 3 in file 
/Users/hansm/TeX/texmf/tex/context/user/type-loc.mkiv: ! Only one # is allowed

   #\cr 1&2\cr 1\cr}

11 you can add a file type-loc.mkiv someplace in your local tree with
12 
13 % dummy file

There should be exactly one # between &'s, when an
\halign or \valign is being set up. In this case you had
more than one, so I'm ignoring all but the first.

mtx-context | fatal error: return code: 256

and using \alignmark and \aligntab this results in:

\starttext
\halign{a\alignmark\aligntab b\alignmark\aligntab c\alignmark\cr 1\aligntab 
2\cr 1\cr}
\stoptext

And I am most curious how my name could turn up in the error message produced!

I've put in what seems to be necessary to fix
the current column of the current alignment.
Try to go on, since this might almost work.

[NTG-context] error in LMTX?

[Hans van der Meer]

This looks to me as an error in the LMTX distribution:

tex error   > tex error on line 6 in file 
/Users/hansm/TeX/context-lmtx/tex/texmf-context/tex/context/fonts/mkiv/type-imp-dejavu.mkiv:
 ! Missing } inserted

 
}
 
\aligntab 
l.6 fontclass\aligntab
\fontclass\cr

Because running under my old ConTeXtBeta does not aborts with the error.
system  > ConTeXt  ver: 2019.06.01 19:11 MKIV beta  fmt: 2019.6.4  int: 
english/english

I looked into that file but could not see what causes the error.
