This seems to be still broken :-( The \intertext{} workaround however is still working, luckily

Hi.
The example with start/stopintertext from 'mathalign.pdf' (My Way, Using \startalign and friends, Aditya Mahajan) gives error with current context (beta): <example file="ex2.tex"> %%% Seems that there is a problem with \start/stopintertext . This command is described in mathalign.pdf %%% (MyWay).
\starttext
Here the start/stopintertext should give text between formulas \startformula \startalign \NC \exp^{\imath t}=\cos t+\imath\sin t\NR \startintertext This is famous Euler formula, below one is known as Moivre formula \stopintertext \NC (\cos x + \imath\sin x)^{m} = \cos mx+\imath\sin mx \NR \stopalign \stopformula
That's it.
\stoptext </example>
! Misplaced \noalign. \startintertext #1\stopintertext ->\noalign {\dointertext {#1}} l.12 \stopintertext ? $ context --version

Is this a bug or I do something wrong?
Bug, and it seems a rather old one. It also fails with 2010.05.24.
has to do with the tex scanner in alignments (doesn't like unexpandable macros)
I cannot debug this right now. A quick workaround is to use \intertext{...} instead. Ok, thanks.
P.S. I thought that all start/stopXXX commands has cousin commands \XXX. Seems that I was wrong.
%D The intertext commands have to be expandable (in aligment lookahead) so %D we cannot use \type {\unexpanded}. \let\stopintertext\relax \def\startintertext#1\stopintertext {\noalign{\dointertext{#1}}} \def\intertext#1% {\noalign{\dointertext{#1}}} ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
