@Kurt, @DavidCarlisle Meanwhile, good morning and excuse me for last night. Unfortunately, the internet connection at my house is very bad. As you notice there are days that I do not connect both for business reasons but also for reasons of poor connection. At the moment I have a break and I write with the usual haste. I will have to modify the whole code referring also to the wrapfig documentation.
Excuse me, everyone, for the sudden absence due to connection internet reasons.

@Sebastiano That really isn't an excuse. You could spend as long as you need to make a sensible example and then just post it when it is done. You have no need to post a question with a long but unusable block of code and then complain about your internet connection. But is your question just why wrapfig does not leave enough space? that is because you force it to only leave 7 lines by [7] and your image is bigger than taht.

@DavidCarlisle David excuse again. But I have not understood all wrapfig package.

@DavidCarlisle With the haste and anxiety that I have I hope to have edited correctly following your instructions. I have inserted in bold if in LaTeX there are interruptions of row or column. Thank you very much.

@DavidCarlisle I have read your last message. The reason of \vspace{-2cm} is because into my file .tex I have this result (see image).
@DavidCarlisle I wanted see the image below and I have putted \vspace{2cm}. The reason is this. Thank you very much.
@DavidCarlisle Welcome. With so much sincerity, I thank you so much for your patience. I don't know how best to edit my question.
\begin{example}
Come campo scalare possiamo prendere ad esempio la funzione scalare \textbf{potenziale elettrico} $\vf$. Tale funzione sarà del tipo: $\vf(P)=\vf \xyz$.
\end{example}

\begin{wrapfigure}{L}{0.4\textwidth}
\centering
\includegraphics[width=0.4\textwidth]{displacement.pdf}
\caption{Vettore posizione $\textbf{r}$.}
\label{fig:sidecap}
\end{wrapfigure}

La variabile indipendente in $\mathbb{R}^3$ si indica molto spesso con $\textbf{r}=|P-O|$ oppure con  $\overline r$, il vettore che è il {\em raggio vettore} o {\em vettore posizione} dall'origine al punto considerato, \$\overl…

@Sebastiano well if you want to ask about such a problem then your example should be an example of that, currently your example is just wrong because you have back spaced the image over the preceding text. Note however that definitions/theorems etc are lists and wrapfig does not support wrapping lists around the image.

@Sebastiano you should be able to replace \includegraphics[width=0.4\textwidth]{displacement.pdf} which is irrelevant to he question by \includegraphics[width=0.4\textwidth]{example-iamge} or \rule{3cm}{4cm}% or whatever size is needed to show the problem
@Sebastiano the very first item in the list of documented issues in wrapfig.sty is
  - You must not specify a wrapfigure in any type of list environment or
or immediately before or immediately after one.  It is OK to follow
a list if there is a blank line ("\par") in between.

@DavidCarlisle Surely all of you will help me to solve the problem of this figure but I will happen another one to whom I have to solve the problem. Sure I've read it but I don't understand what I have to do is also a reason for my question.

@DavidCarlisle did Frank we broke tabu?

4:37 PM
@UlrikeFischer I blame you.

@DavidCarlisle I'd like to edit my question as best I can, but I don't know how to do it. If I insert a lot of text the situation is simple but when I have theorems or other problems arise that you have seen.
@UlrikeFischer Hi, kind Ulrike

@DavidCarlisle I deny any reponsability with everything involving a tabular ;-).

@Sebastiano as I say, wrapfig doesn't support wrapping definitions. In particular cases you can usually force any requred output but there is no general case (and you haven't provided any usable example)

@UlrikeFischer well if you didn't break it, presumably @DavidCarlisle just introduced some undocumented features.

@UlrikeFischer you accepted being a member of the team, so you naturally have to accept accept the blame until such time that you can con someone else in to being last one in..

4:40 PM
@DavidCarlisle But is there an alternative of wrapfig in these cases?

@Sebastiano not as a generally available package as far as I know. (although cutins and picinpar sometimes work when wrapfig doesn't, but usually it's possible to make wrapfig work but it all depends...

@DavidCarlisle I get it now. However, according to my humble opinion, I cannot reproduce the same problem. Changing fonts and deleting some packages presents another problem. I will eliminate my question. It doesn't matter and I'm sorry I made you waste a lot of time and anger.
Best regards to everyone.

@Sebastiano why do you always say people are angry?

5:05 PM
@DavidCarlisle Because I'm so sorry when I waste my time and maybe I think I'm harassing them.
@Skillmon Hi and good chat

@Sebastiano but that isn't the same as accusing people of being angry

@DavidCarlisle Real anger comes from tick stealing. :)

@AlanMunn yes or @marmot claiming a more beautiful avatar

@DavidCarlisle The only thing more beautiful than your avatar would be your avatar done in picture mode.

@DavidCarlisle why does longtable do a \let\@auxout\@auxout? That seems like a strange no-op :)

6:25 PM
@DavidCarlisle I did not claim that. Well, thinking about it, it would have made a whole lot of sense to claim it. ;-)

@Skillmon ?

@DavidCarlisle funny. It doesn't in its code, but in the documentation there is a \let\@auxout\@auxout in the implementation part. Since I thought this must be autocreated from the real code with docstrip, it should be in the code, but it isn't apparantly.

@Skillmon oh I think I remember, it used to have its own private "aux" file for latex2.09 classes that didn't have an aux file, but in the 2e version I commented out the initial setup then globally changed whatever the macro used to be called to \@auxout as it always uses the standard aux file in 2e. hence the line you see...
@Skillmon ah yes it used to ne \let\LT@Out\@auxout:
% \begin{macro}{\LT@out}
% In a normal style, "longtable" uses the ".aux" file to record the
% column widths. With "letter.sty", use a separate ".lta" file.
%
% Not needed for new letter class.
%\begin{verbatim}
%\ifx\startlabels\undefined
%  \let\@auxout\@auxout
%\else
%  {\@input{\jobname.lta}}%
%  \newwrite\@auxout
%  \immediate\openout\@auxout=\jobname.lta
%\fi
%\end{verbatim}
% \end{macro}

@DavidCarlisle Well it lands in the documentation without being a comment.
@DavidCarlisle but without line numbers, so I could've guessed.

@Skillmon if you look carefully you can tell ah I see you spotted...

ha, that was quick :)

@DavidCarlisle I value fairness and respect very much. When I'm wrong and when it's right to apologize I do it right away. I don't agree with your point of view. I have so many flaws and I always hope that those on the other side will understand that I am in good faith. I personally thank you and everyone for their collaboration.

@Sebastiano but as I say, that doesn't explain why you repeatedly accuse people of being angry.

@Sebastiano Why should I be angry?
Dec 26 '16 at 23:42, by David Carlisle
@Sebastiano over and over again you say people are getting angry with you, they are not:-)
etc...

9:08 PM
@DavidCarlisle To be honest, I'm not accusing anyone. I've been writing this since I was a child because I don't want to lose the friendship and esteem of the humble people I respect. That's why I write if I make someone angry. Maybe I write something that could affect the sensitivity of others. I feel sorry when I lose a friendship. That's all.

Dear Dr. Paulo Cereda,

It’s our great pleasure to announce you as speaker for the “Annual Summit on Endoscopy and Advances in Otolaryngology” from July 25-26, 2019 in Singapore.

The 2019 Annual Meeting offers many continuing education sessions, including invited symposia, workshops, and meet-the-expert sessions.

[...]
Looks legit. :)

@Sebastiano perhaps in Italian it reads better, but in English it reads as a rebuke to the person you are addressing.

10:19 PM
@PauloCereda I get those with a rate of more than one per week. Let me guess: the conference fee is substantial, and the organizers have email addresses that end with com?

@DavidCarlisle I guarantee you 100% that's not the case. I would not allow myself to reproach anyone for no reason. I use deepl translator with the hope that the translation is very close to Italian.
@marmot Hi, :) superman :)
@PauloCereda Your hat is wonderful. :). ciao.

@Sebastiano well as you have been told several times, saying someone gets angry in a forum like this is a criticism of that person, and if you don't intend to criticise you shouldn't do it.

@DavidCarlisle Just to let you know, the journal that produced this mess does ask a publication few. Perhaps for making the submission more thrilling? ;-)
