Toggle links globally using macro

Question

I'm writing a CV for my wife using moderncv. We're not sure whether her supervisor wants links in the document, so every time a link might be required, I write the text twice:

PhD student at the Weizmann Institute of Science
% PhD student at the \textcolor{cyan}{\href{http://www.weizmann.ac.il/}{Weizmann Institute of Science}}}

If the tutor decides that we should use links, I will comment out the unlinke text:

% PhD student at the Weizmann Institute of Science
PhD student at the \textcolor{cyan}{\href{http://www.weizmann.ac.il/}{Weizmann Institute of Science}}}

I don't like duplicating code, so I was looking for a way to define a Tex macro for my link style. Perhaps something like:

PhD student at the {\myhref{http://www.weizmann.ac.il/}{Weizmann Institute of Science}}

Where \myhref is defined once at the top, where I can toggle the links on and off, and set the link colors if they exist.

Is there a way to define a global, custom macro in tex?

Answer 1

This is all I can say without an MWE. Maybe it works for you.

\documentclass{article}
\usepackage{hyperref, etoolbox}

\newtoggle{supervisor}
%\toggletrue{supervisor}

\newcommand{\myhref}[2]{%
  \iftoggle{supervisor}%
    {\href{#1}{#2}}%
    {#2}%
}

\begin{document}
PhD student at the \myhref{http://www.weizmann.ac.il/}{Weizmann Institute of Science}
\end{document}

As for the link color, I suggest you use the options provided by hyperref (colorlinks, urlcolor etc.)

Answer 2

This should work.

%% With link
\newcommand{\myhref}[2]{%
  \textcolor{cyan}{\href{#1}{#2}}}

%% Without link
% \newcommand{\myhref}[2]{#2}
