Hi all,
If I use iffirstargument, the optional (first argument) is always seen as false.
If I use doifsomething, it works, but the “else” part is never executed when it
should.
MWE:
\starttext
% \def\MyRow{\dosingleempty\doMyRow}
% \def\doMyRow[#1]#2#3#4#5{%
% \bTR \bTD #2 \eTD %
% \iffirstargument
% \bTD Replaced! \eTD %
% \else
% \bTD #3 \eTD %
% \fi
% \bTD #4 \eTD \bTD #5 \eTD \eTR
% }
\def\MyRow{\dosingleempty\doMyRow}
\def\doMyRow[#1]#2#3#4#5{%
\bTR \bTD #2 \eTD %
\doifsomething{#1}
{\bTD Replaced! \eTD }%
{\bTD #3 \eTD }%
\bTD #4 \eTD \bTD #5 \eTD \eTR
}
\bTABLE
\bTABLEbody
\MyRow{A}{B}{C}{D}
\MyRow[optional]{A}{B}{C}{D}
\eTABLEbody
\eTABLE
\stoptext
Regards
Jon
