# Toggling the visibility of personal notes within a paragraph

In a LaTeX document I'm writing, I'm using the Comment package to write personal notes that I can enable and disable at will, as in the next example:

\documentclass[12pt]{article}
\usepackage{color}
\definecolor{note_text}{rgb}{0.7,0,0}
\usepackage{comment}
\specialcomment{note}{\begingroup\color{note_text}}{\endgroup}
% Uncomment the next line for public version without personal notes
%\excludecomment{note}

\begin{document}

This is a serious sentence.

\begin{note}
This is a personal note
\end{note}

\end{document}


Then by toggling between \excludecomment{note} and %\excludecomment{note} in the preamble, I can choose whether the document includes my personal notes or not. So far, so good.

Now comes my question: how can I do something similar with inline text within a paragraph? I would like to do something like the following:

This is a serious \note{(or not??)} sentence.


But of course that doesn't work as "note" has been defined as an environment through the \specialcomment command. So, is there any way I can use the Comment package to do this? Or some other solution?

For example:

\newif\ifmynotes
\mynotestrue

\definecolor{notetext}{rgb}{0.7,0,0}
\def\mynote#1{\ifmynotes\textcolor{notetext}{#1}\else\fi}


With the usage \mynote{This ia a note}. And if you want to hide your notes, you write \mynotesfalse.

• you might want to add an \ignorespaces between \else and \fi. Otherwise, you will have two spaces with \mynotesfalse. – jakun Sep 21 '17 at 10:04
• This rocks, thanks! There's only a minor problem left, which I haven't been able to fix with @jakun's \ignorespaces. What if I have the inline comment in front of a punctutation mark, like This is a serious sentence\note{ (or not??)}.? Ideally, I'd like it to appear as either "This is a serious sentence." or "This is a serious sentence (or not??)." But I'm finding it tricky to get the space before the parenthesis when notes are enabled. – Ángel José Riesgo Sep 21 '17 at 12:39
• @ÁngelJoséRiesgo replace \ignorespaces with \unskip. \ignorespaces eats up following spaces, \unskip eats up preceding spaces. (At first I thought it wouldn't matter which one to use here, but it seems I did not think far enough. Good point.) – jakun Sep 22 '17 at 9:16
• Thanks, @jakun. That's great; it now works perfectly. I can now write 'This is a serious sentence \note{(or not??)}.' and the whitespace after "sentence" vanishes when disabling the notes. – Ángel José Riesgo Sep 22 '17 at 11:52
