Use " quote in a German document

Question

I have a German document with snippets of code where I need the " symbol as it is. Normally, if I insert an empty space after it, I get it printed, but this does not always work:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[ngerman]{babel}

\begin{document}

\texttt{inventar <- read\_excel(" inventar.xlsx")}

\end{document}

Generates:

---

For the record:

\texttt{inventar <- read\_excel(``inventar.xlsx'')}.

Typesets the following (two single quote chars):

---

Is there a pragmatic way I can print these quotes reliably?

Answer 1

ngerman makes " active to type Umlauts (and ß). If you don't have a lot of code (in which case I would recommend a dedicated package) use a simple \verb. Alternatively, if for some reason (e.g. the string appears in the argument of some other macro) you can add an empty group after " or use the macro \textquotedbl; for the latter you need the T1 font encoding but if you are writing in German that should be used anyway.

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}

\begin{document}

Possible:
\texttt{inventar <- read\_excel("{}inventar.xlsx")}

Also possible:
\texttt{inventar <- read\_excel(\textquotedbl inventar.xlsx\textquotedbl)}

Much, much easier:
\verb+inventar <- read_excel("inventar.xlsx")+

\end{document}
