issue when the encapsulation ‘startitem stopitem’ command is in another self-defined command
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. 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% {\begingroup % \ifarguments 0\or :1\or +2\or =3\or !4\fi \def\currentchitem{#chitem}% \edef\p_correctmark{*}\edef\p_paramark{#mark}% \calc_maxwidth{#choice}% \ifx\p_paramark\p_correctmark \markedchoice{#choice}% \else \normalchoice{#choice}% \fi\endgroup} \def\stopnamedchitem{} \definechitem[chitem] \protect \startitemize[n,horizontal,two]% % The process of calculating the number of formattable columns % has been removed and the results of the calculations are used directly. \startchitem xxx\stopchitem \startchitem[*]correct choice\stopchitem \startchitem xxx\stopchitem \startchitem xxx\stopchitem \stopitemize \stoptext %%%%% thanks for any help, autumnus

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
hi, Wolfgang Sorry, but after I tested it, it did output all the lists and their ordinal numbers. However, if I used the horizontal parameter, it didn't go the way I expected. The expected output item 1 sym @ item 3 item 4 But the actual output is: sym @ item 1 item 3 item 4 But if I remove the horizontal argument, the list is laid out in the normal order: item 1 sym @ item 3 item 4 What should I do with it? thanks, autumnus

hi, Wolfgang
Sorry, but after I tested it, it did output all the lists and their ordinal numbers. However, if I used the horizontal parameter, it didn't go the way I expected.
The expected output item 1 sym @ item 3 item 4
But the actual output is: sym @ item 1 item 3 item 4
But if I remove the horizontal argument, the list is laid out in the normal order: item 1 sym @ item 3 item 4
What should I do with it?
When you use the "horizontal" or "random" option Context collects all item entries enclosed in a \startitem / \stopitem pair and flushes the collection at the end of the itemize environment. All normal entries which don't use them item-pair are placed as is before the collected entries. While there is a \startspecialitem / \stopspecialitem pair with a \sym option, the entries aren't collected at the moment. Wolfgang
