Re: [NTG-context] Check the character after a macro

Hi, You have several commands in ConTeXt doing what you are seeking to do: please look at the examples below: %%% begin do-if-inset.tex \starttext \type{\doifinset{A}{A,B,C}{should go}:} \doifinset{A}{A,B,C}{should go} \type{\doifinset{D}{A,B,C}{should go}:} \doifinset{D}{A,B,C}{should participate} \type{\doifnotinset{}{A,B,C}{not in the set}:} \doifnotinset{}{A,B,C}{not in the set} \type{\doifnotinset{D}{A,B,C}{not in the set}:} \doifnotinset{D}{A,B,C}{not in the set} \doifinsetelse{D}{A,B,C}{it is in the set}{it is not in the set} \define\test{B} \type{\doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the set}} \doifinsetelse{\test}{A,B,C}{\test\ is in the set}{\test\ is not in the set} \stoptext %%% end do-if-inset.tex Best regards: OK

Hello,

Is it possible to check (in a macro definition) if the character following the macro is included in a set of characters?

Something that could work like this:

\def\MyMacro#1{% \ifNextCharIn{abcd} \dothis% \else \dothat% \fi% }
