Re: [NTG-context] error in LMTX?

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.

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

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

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#&b#&c#\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 per tab

l.3 \halign{a#&b# &c#\cr 1&2\cr 1\cr}

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.
