Quote environment with reference at the end right

Question

I want to define a quote environment such that after the quote on the right occurs the author with page number. My solution is yet the redefinition of the quote environment

\usepackage{amsthm} % pushQED, popQED
\newenvironment{aquote}[1]{%
  \pushQED{#1}%
  \begin{quote}
}{%
  \par\nointerlineskip\noindent\hfill(\popQED)%
  \end{quote}%
}

with the following result:

The drawback is the parskip in front of the author, which wastes some space in the first quote, but is right in the second one. If I change my command to:

\newenvironment{aquote}[1]{%
  \pushQED{#1}%
  \begin{quote}
}{%
  \noindent\hfill(\popQED)%
  \end{quote}%
}

I get the following result:

Now the placement of the author's name in the first quote is perfect, but in the second quote I want a parskip in front, like in my first example.

How can I find out, whether the line has enough space to put the author without a parskip behind or if there is not enough space to introduce a parskip to put the author on the next line?

There's a nice \signed macro that serves this purpose on page 106 of the TeXbook; here's a little variation used to build the aquote environment which behaves as expected;

\documentclass{book}

\def\signed #1{{\leavevmode\unskip\nobreak\hfil\penalty50\hskip2em
  \hbox{}\nobreak\hfil(#1)%
  \parfillskip=0pt \finalhyphendemerits=0 \endgraf}}

\newsavebox\mybox
\newenvironment{aquote}[1]
  {\savebox\mybox{#1}\begin{quote}}
  {\signed{\usebox\mybox}\end{quote}}

\begin{document}

\begin{aquote}{Bourbaki}
This is a case where the name fits in nicely with the quote so the name will appear in the same line.
\end{aquote}

\begin{aquote}{Nicolas Bourbaki}
This is a case where the name won't fit in nicely with the quote, and in this case the name will be moved to the next line.
\end{aquote}

\end{document}

Here's the result:

Thank you! Exactly, what I searched for. Also many thanks for the exact reference in the TeXbook. – FredericChopin Mar 18 '11 at 07:31
Why do you need the the \savebox? Is parameter #1 otherwise unavailable in the closing part of the environment? – Christian Lindig Mar 18 '11 at 19:22

@Christian Lindig: yes,you are right, when defining a new environment, you cannot specify parameters directly in the closing part of the definition; the standard trick is to store them in boxes in the opening part and use the boxes in the closing part. – Gonzalo Medina Mar 18 '11 at 19:37

{\savebox\mybox{(\expandafter\scantokens\expandafter{\detokenize{#1}}\unskip)}\begin{quote}\it} allow to use \bibleref inside when : has a 13 catcode. Cf https://framagit.org/maieul/bibleref/issues/13#note_283589 – Maïeul Jul 28 '18 at 12:20

@GonzaloMedina : would it be possible to modify this aquote environment to cancel the white space that comes after it (to use it in a footnote, for example)? Thanks. – Tobard Aug 13 '18 at 10:26
Unfortunately, cannot use the \signed macro inside \paragraph: "\pdfendlink cannot be used in vertical mode" – user612313 Sep 18 '19 at 09:11
Could you please make some explanations to the design of \signed? – Stephen Jun 26 '23 at 07:06

Also for completeness, please refer to the attrib package. You can approximate the effect you want with the following:

\begin{quote}
  We call a disposition the arrangement of that which has parts, in respect 
  either of place or of capacity or of kind; for there must be a certain 
  position, as the word ‘disposition’ shows.

  \attrib{{\em Metaphysics} {\greektext D}.19, 1022b1--3}
\end{quote}

Welcome to TeX.sx! – Peter Jansson Mar 11 '13 at 17:22
This doesn't answer the question, though, because it will always put the attribution on a new line, even if there's room on the existing one. – cfr Jan 09 '16 at 02:01
@cfr If you don't put the blank line between the paragraph and \attrib, the reference will appear in-line. See the examples in the documentation for the LaTeX Frankenstein package. – phantom-99w Apr 09 '17 at 18:32

@phantom-99w Which sort of proves my point. – cfr Apr 09 '17 at 20:54

I just want to add for completeness that the memoir package provides the

\sourceatright[⟨length⟩]{⟨text⟩}

command, which can be used immediately after a quote or quotation environment and does what the question asks.

In my opinion, the simplest variant I found to achieve this

\begin{quote}
  The only way to make the deadline—the only way to go fast—is to keep the code as clean as possible at all times.
  \begin{flushright}
    \tiny{---Robert C. Martin, Clean Code}
  \end{flushright}
\end{quote}

Like the answer above this doesn't answer the question, because it will always put the author on a new line, even if there's room on the existing one. – dexteritas Jan 11 '18 at 09:25
