Hi all, for some weeks I need to tex formulas again and tried the way I used to do it:
\placeformula $$ f(t)={1\over2\pi}\int_0^\infty e^{i(\omega t-kx)} dx $$
It didn't work anymore?!? It doesn't place a number nor does it do the spacing properly. It does work the "context" way using
\placeformula \startformula f(t)={1\over2\pi}\int_0^\infty e^{i(\omega t-kx)} dx \stopformula
This is a bug in doplaceformula. I do not know how to avoid it, but the next code illustrates what is happening. \def\dotest{ \def\nextnext{$}% \ifx\next\nextnext Inside dispplaceformula\ldots % This always fails \else Inside dodoplaceformula\ldots \fi} \def\test{\futurelet\next\dotest} \test$$A = B$$ This prints "Inside dodoplaceformula" even though the next character is \$. So, the \next=\nextnext branch never matches. I do not know why this happens, but a more robust check is needed in doplaceformula. Aditya
