This is \Var{var_name}, a variable.

What about:

Thank you, Khaled, for the response. This solution works as is. But it has a problem as soon as you want to put double quotes around the variable name. Simply replacing the single quotes with double quotes in your solution doesn't produce open- and close-quotes pairs: ================== \def\Var#1#2{"\type{#1}% \directlua{ if "#2" == "," then tex.sprint('#2"') else tex.sprint('"#2') end}} ================== In order to do that, you need (I think) to use the \quotation{} command: ================== \def\Var#1#2{\quotation{\type{#1}% \directlua{ if "#2" == "," then tex.sprint("#2}") else tex.sprint("}#2") end}} ================== resulting in: ================== ! Too many }'s. l.7 end}} ================== I also tried \bgroup...\egroup: ================== \def\Var#1#2{\quotation\bgroup\type{#1}% \directlua{ if "#2" == "," then tex.sprint("#2\egroup ") else tex.sprint("\egroup #2") end}} ================== giving: ================== ! Missing } inserted. <inserted text> } <to be read again> \normalend l.18 \stoptext ================== Thanks again! Tad
