Question
How can I \renewcommand{\todo}
to give single spacing in the todonotes of an otherwise double spaced document?
What I have tried
The documentation (p. 11, section 1.8.6) suggests that something like this should work (with todonotes.sty in the proper directory), but it doesn't:
\documentclass[12pt]{article}
\usepackage{setspace}
\doublespacing
\usepackage[backgroundcolor=white,textsize=tiny]{todonotes}
\newcommand{\smalltodo}[2][]
{\todo
{\begin{spacing}{0.5}#2\end{spacing}}}
\begin{document}
\smalltodo[inline]{testing todonotes here with single spacing}
\end{document}
giving the following error:
Runaway argument?
{\todo {\begin {spacing}{0.5}##2\end {spacing}} \ETC.
! File ended while scanning use of \@xargdef.
But I can't figure out the error.
Once I get this to work, can I just replace \newcommand{\smalltodo}
with \renewcommand{\todo}
?
Best Answer
While I don't know why it doesn't compile for you, here is an answer to your second question:
No, you can't just use
\renewcommend
as that would create an infinite loop; every call to\todo
would have another call to\todo
inside it. However,\todo
is actually just an alias for\@todo
(apparently the author thought that people might want to redefine it), so you can simply do the following:
