[NTG-context] nesting commands with optional arguments
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
This is what I get:
! Use of \doOne doesn't match its definition.

Re: [NTG-context] nesting commands with optional arguments
Of course, should have tried that … thanks!
btw. since when is this working? (I tried it with a pretty old minimal
from 2011-08, where I got this error)
