hi,
I'm creating a command that can format multiple choice questions on my own. I've done most of it at the moment. But I want more, so I'm trying to create more versions of this command that is already nearing completion. So I'm using the following command to create a command with more possibilities.
I've noticed that ‘startitem stopitem’ isn't working.
You can't put the items in a group. \starttext before \startitemize[n,horizontal,two] \begingroup\startitem aaa\stopitem\endgroup \begingroup\startitem bbb\stopitem\endgroup \stopitemize after \stoptext
Their location and serial number are anomalous.
%%%% Removed some unnecessary commands to show what the problem was. % macros=mkvi \starttext \unprotect \installnamespace {chitem} \installcommandhandler \????chitem {chitem} \????chitem
\appendtoks \setuevalue{\e!start\currentchitem}{\startnamedchitem [\currentchitem]}% \setuevalue{\e!stop \currentchitem}{\stopnamedchitem}% \to \everydefinechitem
\tolerant\protected\def\markedchoice#1{{\sym{@} \red sym : #1}} \tolerant\protected\def\normalchoice#1{\startitem normal : #1\stopitem} \tolerant\protected\def\\calc_maxwidth#1{} %The longest option text is calculated by comparison to % determine the number of columns that can be typeset
\tolerant\protected\def\startnamedchitem[#chitem]#*[#mark]#*[#option]#*#choice\stopnamedchitem%
You can't use \stopnamedchitem as delimiter for the environment, what TeX has to see is the new \stopchitem command. One method to achieve this is \grabuntil with a processing function. \tolerant\protected\def\startnamedchitem[#1]#*[#2]#*[#3]% {\begingroup \edef\currentchitem{#1}% \edef\m_mark{#2}% \grabuntil{\e!stop\currentchitem}\process_chitem} \def\process_chitem#1% {\ifx\m_mark\wildcardsymbol \aftergroup\markedchoice \else \aftergroup\normalchoice \fi \endgroup{#1}} Wolfgang
