Using \doifelse to change the itemization symbol in specific cases

Using \doifelse to change the itemization symbol in specific cases

[Kevin Kenan]

I’m trying to create a conditional that changes the symbol used for certain item numbers. Here’s my code that doesn’t work.

\define[1]\StepsCommand{\doifelse{#1}{2}{k}{#1}\ignorespaces}
\defineitemgroup[Steps]
\setupitemgroup[Steps][each][n,packed]
\setupitemgroup[Steps][each][left=\StepsCommand]

\starttext
\startSteps
\item A
\item B % the item number should be replaced with 'k'
\item C 
\stopSteps
\stoptext

The second item “B” should have the letter ‘k’ instead of the number “2.” Is this possible?

Thanks,
-kk

You can set custom symbols for individual items with \txt but this won't 
increment the item counter. To continue the counter and replace some 
symbol you have to create your own number conversion.

\defineconversion [kevin] [1,k,3,4,5,6,7,8,9]

\starttext

\startitemize[n]
\item A
\txt{k} B
\item C
\stopitemize

\blank[2*line]

\startitemize[kevin]
\item A
\item B
\item C
\stopitemize

\stoptext

Ah…thanks for the pointer to \definecoversion. Looks promising.

I had also tried:

\defineitemgroup[Steps]
\setupitemgroup[Steps][each][n,packed]

\starttext
\startSteps
\item A
\sym{k} B\incrementnumber[itemgroup:Steps]
\item C 
\stopSteps
\stoptext

Which is similar to your \txt solution and increments the counter.

Thanks again for the help.

\starttext

\startitemize[n]
\item A
\txt{k} B
\noitem
\item C
\stopitemize

\stoptext
