csquotes: always enclose blockquote in " "

Question

I'm trying to force csquotes to always set a \blockquote in display mode but still enclose the quote in quotation marks, German ones in particular.

How can I achieve that?

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern,blindtext}

\usepackage[babel=true,strict=true,german=quotes,threshold=1]{csquotes}

\begin{document}

\blindtext

\blockquote{\blindtext}

\blindtext

\end{document}

This example produces a quote as an indented paragraph, but without quotation marks.

Answer 1

The csquotes manual suggests to redefine \mkblockquote, see section 8.7 Hooks for Quotations and Citations. One possibility would be

\renewcommand\mkblockquote[4]{\enquote{#1#2#3}#4}

which gives the same effect as in this answer.

The four arguments of \mkblockquote refer to

\mkblockquote{<text>}{<punct>}{<tpunct>}{<cite>}

which are explained in the manual as follows

• #1 The text argument of the command.
• #2 The optional <punct> argument of the command. If there is no <punct> argument, this parameter is empty.
• #3 Trailing <tpunct> punctuation immediately after the command. If there is no such punctuation or if the autopunct feature is disabled, this parameter is empty.
• #4 The optional <cite> argument of the command, wrapped in \mkcitation. If there is no <cite> argument, this parameter is empty. With integrated quotation commands, this parameter is the citation code, wrapped in \mkccitation.

In the example below I use

\renewcommand\mkblockquote[4]{\leavevmode\llap{,,}#1#2#3``#4}

where \llap{,,} places the opening quotation mark left of the text in the quote margin. (The space at the end before the closing quotation mark is an artefact of \blindtext and not related to \mkblockquote.)

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern,blindtext}

\usepackage[babel=true,strict=true,german=quotes,threshold=1]{csquotes}

\renewcommand\mkblockquote[4]{\leavevmode\llap{,,}#1#2#3``#4}

\begin{document}

\blindtext

\blockquote{\blindtext}

\blindtext

\end{document}

Answer 2

Just add \enquote{...} inside the \blockquote command.

MWE:

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
\usepackage{lmodern,blindtext}

\usepackage[babel=true,strict=true,german=quotes,threshold=1]{csquotes}

\begin{document}
\blindtext

\blockquote{\enquote{\blindtext}}   %<=======================

\blindtext
\end{document}

Answer 3

I added threshold=1 and thresholdtype=words to the \usepackage-Command to enforce blockquotes even at short quotations.

The threshold option refers to words or lines (default). In combination with thresholdtype=words the threshold for block-quotes can be set to one word.

For me the following command worked well until now:

\usepackage[autostyle=false, style=english, threshold=1, thresholdtype=words]{csquotes}

The package documentation at page 4 shows the following options:

threshold=〈integer〉

default:3

This option defines the number of lines or words the block quotation facilities useas a threshold when determining whether a quotation should be typeset in inline orin display mode. It corresponds to the\SetBlockThresholdcommand. See §§ 3.5and 8.6 for further details.

thresholdtype=lines

wordsdefault:lines

This option selects the block threshold type. Withthresholdtype=lines, the blockquotation facilities will determine the number of lines required to typeset the quo-tation; withthresholdtype=words, they count the number of words in the quota-tion.3The default threshold setup is 3 lines. If you prefer something like 50 words,setthreshold=50andthresholdtype=words. See § 3.5 for further detail
