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?
