LaTeX newcommand with verbatim or listings : problem with `#` (hash key)

I'm trying to define a macro with newcommand using verbatim or listings environment. It seems that the hash key in #1 (standing for the argument) is escaped, due to verbatim and listings.

I'm new to macros, so I tried something simple : it works with begin{center} ... end{center}.

documentclass[a4paper,oneside,11pt]{report}

newcommand{script}[1]{

  begin{center}

    #1

  end{center}

}

begin{document}

  script{blabla}

  blibli

end{document}

When I replace center with verbatim, I get this error :

File ended while scanning use of @xverbatim.

or lstlisting :

Text dropped after begin of listing

I didn't find anything on stackoverflow nor https://tex.stackexchange.com : what would you advise to use those environments in macros (newcommand or maybe newenvironment) ?

Thanks in advance

What is the aim here? Verbatim content cannot be passed as an argument to other macros.

I'd like 1) to paste scripts and code without having to escape characters 2) make a minipage or sthg else, maybe a box, to distinguish between code and normal text in the page.

By "scripts of code" are you referring to the actual code? I would suggest writing your own environment based on listings.

I'm making a tutorial in which I use PHP, bash, Sparql. But I'd like to paste any text with special chars. What do you mean with > writing your own environment based on listings. ? Is there a simple manner to do so (haven't found yet)?

Verbatim content is tricky. You have to ask yourself what the intent is. If it's printing code, then king of the hill would be listings. I'd suggest that and define your own environment for large chunks of code-specific output.

Here's an example:

enter image description here

documentclass{article}



usepackage{listings}



lstnewenvironment{code}[1]

  {lstset{#1}}% Add/update settings locally

  {}



lstset{% Global options

  frame = single,

  basicstyle = ttfamilysmall,

  language = PHP

}



begin{document}



My first PHP ``Hello World'' page:



begin{code}

<html>

 <head>

  <title>PHP Test</title>

 </head>

 <body>

 <?php echo '<p>Hello World</p>'; ?> 

 </body>

</html>

end{code}



When you write lstinline!<title>PHP Test</test>!, it sets the textit{title} of the page.



end{document}

Thank you very much Werner, you convinced me to learn more about listings. Didn't know of lstinline. Could you just explain the syntax of {lstset{#1}} : does it mean I can add an option as argument?

– vvffl

@vvffl: Yes. I defined code as an environment that can take an optional argument. So you can call (say) begin{code}[language = bash]...end{code} to switch the language. It would probably be ideal for you to define a style depending on the language (styles include colour and other formatting specifications).

Thanks, it's exactly what I thought (I have somewhere in my tex files an old paper where I used custom syntax color for xml, so I'm going to 'grep' that first). So macros aren't that difficult, but the syntax still looks weird for me.

@vvffl: This is a common requirement, but it's not well-supported. See Viewer-independent copyable spaces at the beginning of a line? The fact that the output (in the resulting PDF) does not include the spaces, they aren't selectable for copy-and-paste. As such, indentation is not preserved. The intent of (La)TeX is to produce beautiful documents and therefore might not fully support the "reverse" where that content is copied/pasted elsewhere.

Found a workaround for verbatim with verb command, and using tilde as delimiter (if I want to use tilde inside the script I have to use textasciitilde):

documentclass{article}



newcommand{scr}[1]{

            }

        }

    end{minipage}  

}   



begin{document}        

    scr{Some script code here...

This does not work. Within a verbatim setting (either within the verbatim environment or verb) macros like textasciitilde are not expanded to their meaning since is changed to represent a character. As such, your output should contain textasciitilde, not ~.

            }

        }

    end{minipage}  

}   



begin{document}        

    scr{Some script code here... 



    here a tilde : textasciitilde

    }

end{document}

But nothing for listings...

EDIT :
I've just noticed that this workaround doesn't keep the "automatic" character escaping, so it's not what I was looking for. I'd like to be able to paste code without escaping special chars.

This does not work. Within a verbatim setting (either within the verbatim environment or verb) macros like textasciitilde are not expanded to their meaning since is changed to represent a character. As such, your output should contain textasciitilde, not ~.

Thanks for your reply. Actually it does work on my install... Don't know how nor why!
