How to Define New Todo Command Which Still Takes Options

Question

I am using the package todonotes in order to handle my TODOs. As written in the manual, one can define a custom TODO command like that:

\newcommand{\feedbackRequired}[1]{\todo[color=red!70]{#1}}

This works in general if one uses it without any options:

\feedbackRequired{Do I have to do that, supervisor?}

But unfortunately, it is not possible to use the new command and give it some extra options like that:

\feedbackRequired[inline]{Do I have to do that, supervisor?}

This will break the output. The tex file will still be compiled, but the TODO note output in the PDF is broken:

How can I solve that problem?

Answer 1

For an optional argument, you must use

\newcommand{\feedbackRequired}[2][]{\todo[color=red!70,#1]{#2}}

The second [] holds the optional argument, in this case it is predefined to be empty, but later on, in your example, it will be inline. Your actual note is contained in the 2nd argument.

\usepackage{todonotes}%
\usepackage{xcolor}%


\newcommand{\feedbackRequired}[2][]{\todo[color=red!70,#1]{#2}}
