Based on the two examples here, the inline form of \todo is modified to allow truly inline todos. However, if the \todo is on a line by itself, a Bad space factor (0). error is generated (sometimes, see code below). Is there a way to have the command work in either context?

\tikzstyle{inlinenotestyle} = [
    line width=0.5pt,
    inner sep = 0.8 ex,
    rounded corners=4pt]

        {\begin{tikzpicture}[remember picture,baseline=(current bounding box.base)]%
            \draw node[inlinenotestyle,font=\@todonotes@sizecommand, anchor=base,baseline]{%
                {\noindent \@todonotes@sizecommand \@todonotes@author:\,\@todonotes@text}%
                {\noindent \@todonotes@sizecommand \@todonotes@text}%

This is \todo[inline]{fine}.

The following breaks if the line above is commented out.

\todo[inline]{a test}
  • You can use \leavevmode\todo[inline]{a test} (but it looks like a bug in todonotes placing of @esphack I think. (incidentally you are defining \mytodo but not using it Jan 13, 2018 at 20:56

Yyou are defining \mytodo (copied from the previous answer) but not using it, using \mytodo instead of \todo[inline] would also fix the problem as it avoids the use of \@bsphack.
