[NTG-context] Wrapping \type{}
In my BNF module I use " as an active character that begins and ends
terminals in the grammar:
: ; , "\|", .
Now, the above doesn't quite work as written, as \ is still active (and
so is, in fact | as we're really inside a \starttabulate.
What I would like for the "" pair to do is work as a wrapper for
\type{}, so that everything in-between is passed on to \type{}.
Is there a way of getting them to do that?
This is my current definition:
\gdef"%
{\ifBNFoutsidestring%
\global\BNFoutsidestringfalse%
\begingroup%
\BNFunsetcatcodes%
\catcode`\"\@@active%
\@@bnfterminalstart%
\else%
\@@bnfterminalstop%
\endgroup%
\global\BNFoutsidestringtrue%
\fi}
I figured something like
\long\gdef"#1"%
{\type{#1}}
might work, but it didn't. It chokes on "." where . is also an
activated character for terminating a production in the grammar.
Any suggestions on how to go about this? I mean, the obvious solution
is simply to write
: ; , "\type{\|}", .
instead, but I would like to keep the input as clean as possible.

Re: Re[2]: [NTG-context] Known nath bugs?
Hi, Yes, this is generally true. All modules should get loaded before \starttext. Well, I had loaded it before \starttext in both cases. But when I loaded it in the first line of my file, it didn't adjust the delimiters; after moving the \usemodule[nath] line directly above the \starttext line, it worked like a charm. Maybe I produced some garbage inbetween. :-) However, the units module still isn't working when nath is loaded. Is it supposed to? [...] Anyway, it looks like the fix is easy: the problem is that dimension commands are not protected (unexpandable). [...] Thank you very much, I'll try that. If it doesn't work, I can still get along without units, though it would have been nice to have that too. BTW, is there some kind of manual on aligning nath equations? I tried to align multiline equations using \startalign, but that only worked (in display mode) as long as no delimiters were used; \[ \startalign a &= (b \\ b &= c) \stopalign \] always produced an error message saying that I had left out an "}". I probably made some mistake, so a tutorial on aligning equations with nath would be great. The nathguide.pdf mentions eqnarray, but I guess that's not available in ConTeXt, or is it?

Well, I had never tested them together, and given the very
extensive changes nath enacts, I'm not surprised it doesn't
work.
Anyway, it looks like the fix is easy: the problem is that
dimension commands are not protected (unexpandable).
In m-units.tex, look for the lines
\def\dimensionprefix#1%
{\gdef\thedimensionprefix{#1}}
\def\dimensionaddfix#1%
{\unskip
%\mathematics{\umathematicstypeface#1}%
\ustartmathmode\umathematicstypeface#1\ustopmathmode
\nobreak
\hskip\dimensionaddfixsignal}
\def\dimensionnopfix#1%
{\dontbreakdimension
\ifdim\scratchdimen=\dimensionpowersignal\relax
\ustartmathmode
\else
\ustartmathmode
\udimensionhalfspace
\nobreak
\fi
\umathematicstypeface#1%
\ustopmathmode
\nobreak
\hskip\dimensionsignal}
\def\dimensionmidfix#1%
{\dontbreakdimension
\ifdim\scratchdimen=\dimensionpowersignal\relax
\ustartmathmode
\udimensionbackspace
\nobreak
\else
\ustartmathmode
\fi
\umathematicstypeface#1%
\ustopmathmode
\nobreak
\hskip\dimensionmidfixsignal}
\def\dimensionpower#1%
{\gdef\thedimensionpower{#1}}
and change each
\def\dimension...
into
\unexpanded\def\dimension
This should solve the problem.
I'm not 100% sure this is the best solution, though. An
alternative could be to keep those definition as they are and
instead make unexpandable the actual commands (\Micro etc).
Hans, what do you think?

No. It seems it's called --purge on my machine, but it seems to do what
you're suggesting :-). Perhaps this is a better solution actually.

in enco-def.tex this is
\definecharacter textbraceleft{\mathematics{\{}}
which means wrapping {\tt ...} around it doesn't give a teletyped brace
but a nice mathematics one.
> \type-{-
This doesn't seem to work well inside a table:
! Missing { inserted.
{
&
\normalTABLEquote ->\unskip \!ttRightGlue &
\omit \tablepos &
\NC ...rentTABLEcolumn \plusone \normalTABLEquote
\fi
l.754 \NC
\type{|} \NC $\}$ \NC \type{~} \NC {\tt DEL} \NC\AR
?
where my .tex source reads:
\NC 120 \NC \type{x} \NC \type{y} \NC \type{z} \NC \type-{-
\NC \type{|} \NC $\}$ \NC \type{~} \NC {\tt DEL} \NC\AR
> \stoptext
It would be great if one could get the second version (\type-{-) working
inside a table, as this is the prettier solution.
Currently I just did my own
\definecharacter textbraceleft 123
(which some of the other enco-*.tex files did) for this and wrapped that
inside a {\tt ...}:
{\tt \textbraceleft}
Anyway, thanks for the suggestions,
nikolai
P.S.
Here's a small testfile:
\starttext
\starttable[|c|]
\NC \type-{- \NC\AR
\stoptable
\stoptext

Yes, I began with that, but the problem is that a lot of files will
still go in the same directory as myfile, such as metapost files a .tmp
and the .tui file. I guess it's not that bad, but I like keeping things
as clean as possible. Perhaps I'm being a bit unreasonable though,
cause having the directory structure that I do complicates some stuff
(such as includes),
