Hi,
With context 2024.08.16 the following gives an error:
\starttext
$A \ldot B$
\stoptext
tex error > tex error on line 2 in file ./test.tex: Control
sequence expected instead of undefined
<line 3.2>
$A \ldot
B$
Same error with `\ldotp`.
However
\starttext
\show\ldot
\show\ldotp
\stoptext
gives
\ldot=permanent \Umathchar"02"00"00002E
\ldotp=permanent \Umathchar"06"00"00002E
which appears correct.
So, not sure what is going on. Any ideas?
I have no idea what's the cause for the error but I can narrow it down.
When you replace \ldot with it's mathchar version you can reproduce the
error when there is *no* space at the end, \ldots on the other hand has
no problem without the space.
\starttext
No space at the end of \tex{Umathchar}:
$\Umathchar"19"00"002026\Umathchar"19"00"002026 $ % \ldots
Space at the end of \tex{Umathchar}:
$\Umathchar"19"00"002026 \Umathchar"19"00"002026 $ % \ldots
No space at the end of \tex{Umathchar}:
% $\Umathchar"02"00"00002E\Umathchar"02"00"00002E $ % \ldot
Space at the end of \tex{Umathchar}:
$\Umathchar"02"00"00002E \Umathchar"02"00"00002E $ % \ldot
\stoptext

good analysis ... quick hack to get Aditya going ...
