Re: [NTG-context] Emulating AMS stuff in ConTeXt

[Hans Hagen]

At 07:24 PM 12/7/2002 +0100, you wrote:

def\startalign{%
    \startformula
    \let\\\cr
    \grabuntil{stopalign}\doeqalign
}
\def\doeqalign#1{\eqalign{#1\cr}\stopformula}

^^ better make that \crcr in order to catch users \\

\let\stopalign\relax

These allow me to write:

\startalign
  a & = b = \\
    & = c
\stopalign

isn't \startmathalign a better choice?

and everything is fine. Yet I cannot do

\placeformula[hook]
\startalign
  a & = b = \\
    & = c
\stopalign

because of expansion problems. Why? How can I define the stuff?

took me a couple of cd's to uncover this -)

(1) placeformula has to look ahead, and the next command is not seen as something math; so,
(2) i made another lookahead, and then
(3) we ran into those \cr & and # things that may not always show up everywhere, so
(4) i had to rewrite a low level macro that i didn't like rewriting, i.e.
(5) i had to use a variant i'd always thought that could be avoided

so, you spoiled my afternoon -)

btw, if you isolate/collect the ams math that's not yet in m-newmat, i can see if/how i can add it there in a configurable way, so if some things fails, we can look into it later

you can try the version i just uploaded
