Suppose I have a macro like this:

\define[1]\thisismylist{

This list has n items.

\startitemize    #1 \stopitemize

}

And in the document it might have this:

\thisismylist{ \item cat \item dog \item tree }

How can I make n display three, as there are three items?

"This list has 3 items:

1. cat 2. dog 3. tree

I will use this as a means to check if the description before a list needs a plural or not:

Read the prompts below:

- Do you think cats should be banned from university dormitories? - Should public schools provide free breakfast?

And that way, if there is only one prompt, it changes the instructions to be:

Read the prompt below:

- Do you think cats should be banned from university dormitories?

When you pass your itemize entries as comma separated list you can use the \getcommalistsize command to count the list entries. Afterwards use \doloopoverlist to create an itemize entry for each text in the comma separated list. %%%% begin example \starttexdefinition protected thisiymylist [#1] \getcommalistsize[#1] \doifelse{\commalistsize}{1} {Read the prompt below:\par} {Read the prompts below:\par} \startitemize \doloopoverlist{#1}{\startitem\recursestring\stopitem} \stopitemize \stoptexdefinition \starttext \thisiymylist [Do you think cats should be banned from university dormitories?, Should public schools provide free breakfast?] \thisiymylist [Do you think cats should be banned from university dormitories?] \stoptext %%%% end example Wolfgang

If your actual items are more complex than those in your example and Wolfgang’s suggestion of iterating over a comma separated list won’t work then ... The following code stores the length of each list in a dataset. The `delay` option ensures the values retrieved are those from the completed run of the document, and a unique id is assigned to each list so subsequent lists don’t overwrite the length calculations for earlier ones. \definecounter [MyItemsCounter] \definecounter [MyItemsUniqueID] [way=bytext] \setcounter [MyItemsUniqueID] [1] \definedataset [MyItems] [delay=yes] \defineitemgroup [MyItems] \setupitemgroup [MyItems] [ before={\setcounter[MyItemsCounter][1]}, inbetween={\incrementcounter[MyItemsCounter]}, after={\setdataset[MyItems][\rawcountervalue[MyItemsUniqueID]][count=\rawcountervalue[MyItemsCounter]]% \incrementcounter[MyItemsUniqueID]}, ] \define\listLen{\datasetvariable{MyItems}{\rawcountervalue[MyItemsUniqueID]}{count}} \define\itemOrItems{\doifelse{\datasetvariable{MyItems}{\rawcountervalue[MyItemsUniqueID]}{count}}{1}{item}{items}} \starttext This list has \listLen\ \itemOrItems. \startMyItems \item cat \item dog \item tree \stopMyItems \blank This list has \listLen\ \itemOrItems. \startMyItems \item cow \stopMyItems \stoptext Regards, — Bruce Horrocks Hampshire, UK
