Dear list, I have a question concerning nesting commands with optional arguments.
I'm trying to put a command with an optional argument inside the optional argument of another one … For sure this is just a simple expansion problem but I have no clue how to handle this …
Thanks for any hints! Daniel
Please consider the following minimal example:
\def\one{\dosingleempty\doOne}
\def\doOne[#1]{% in 1st: \doifsomethingelse{#1}{#1}{no arg}\par% }
\def\two{\dosingleempty\doTwo}
\def\doTwo[#1]{% in 2nd: \doifsomethingelse{#1}{#1}{no arg}\par% }
\def\three#1{in 3rd: #1\par}
\starttext \one\two \blank \one[\three{myArg}] \blank \one[\two[Argument]] \stoptext
\one[{\two[Argument]}]
