How to do \newcommand{\filepath}[1]{\verb!#1!}?

Question

I want to define a command \filepath so that I can use \filepath{foo_bar.cpp} and it is printed in monospaced font.

Also, why does this not work? I get strange errors:

\newcommand{\filepath}[1]{\verb!#1!}

How? It should not print the content but the filename. Like I'm trying to do in the title of the question. — Albert, Jun 06 '13 at 18:42

@MarcoDaniel: The answer here is better than in the other question. For example, there is always a possible character where it would fail but I don't want that. — Albert, Jun 06 '13 at 18:57
@MarcoDaniel: Which one? I just checked url.sty and it seems they have found a (complicated) way to read the argument verbatim (search "reading the argument verbatim"). — Albert, Jun 06 '13 at 19:01

I think you are re-inventing the wheel. The package url provides a command \path.

\documentclass[obeyspaces]{article}
\usepackage{hyperref}
%\usepackage{url}
\begin{document}

\url{aa/bb_cc/dd.foo}

\path{aa/bb_cc/dd.foo}

\path{C:\Program Files\Mozilla Firefox}
\end{document}

enter image description here

The option obeyspaces is passed to url package (which is loaded by hyperref) so that spaces in the path are respected (see the third line in image).

That does not work in a title. But I'm using now \newcommand{\filepath}[1]{\protect\path{#1}} which does. Thanks! – Albert Jun 07 '13 at 09:26
@Albert Fragile commands need to be \protected in moving arguments. Or you may use the optional arguments for titles: \section[short title]{{File \path{foo.cpp}} – Jun 07 '13 at 13:33

perhaps the best way is to use

\usepackage{url}
\DeclareUrlCommand\filepath{}

enter image description here

\documentclass{article}

\usepackage{hyperref}

%\usepackage{url}
\DeclareUrlCommand\filepath{}

\begin{document}

\url{aa/bb_cc/dd.foo}

\filepath{aa/bb_cc/dd.foo}

\end{document}

Note \url becomes clickable but not \filepath in the hyperref version.

I already have hyperref included and I use \url for URLs. It's almost like I want it to be for \filepath, except that it is clickable. – Albert Jun 06 '13 at 18:45
@David: This time your miracle failed ;-) – Marco Daniel Jun 06 '13 at 18:48
@Albert Ok so you just want the original url.sty version without the hyper support, I will just check the incantation required... – David Carlisle Jun 06 '13 at 18:51
I just tested and it seems that the version from \DeclareUrlCommand is not clickable but other \urls are, so it's already like I want it. Whereby I would not have expected it to not be clickable. – Albert Jun 06 '13 at 18:52
@Albert it works fro me, see update – David Carlisle Jun 06 '13 at 18:54
It doesn't work if it is inside of a title. Like in \section{File \filepath{foo.cpp}}. – Albert Jun 06 '13 at 19:04
@Albert \protect\filepath – David Carlisle Jun 06 '13 at 19:26
@DavidCarlisle There is \path command provided by url Can you please add it to your answer so that I will delete mine :-) – Jun 06 '13 at 22:59
@HarishKumar nah, I'll vote for yours instead (for the obeyspaces bit, mostly) – David Carlisle Jun 06 '13 at 23:03
