TeX, LaTeX and Friends

6:01 AM

@AlanMunn oh my! :)

@DavidCarlisle ooh tell me more

6:13 AM

John Hurt passed away. :( He was brilliant as the War Doctor.

8:00 AM

@PauloCereda no

9:13 AM

@AlanMunn No piano has been harmed during the production of this video

@PauloCereda They're planning a new release of LaTeX that would output random text when a thesis is being compiled by a duck fan and SP citizen PhD student.

9:55 AM

@egreg True, but fortunately @PauloCereda is safe as he has no such text.

@DavidCarlisle Maybe he can try: random text is better than no text.

@egreg for a Doctor of Philosophy degree you really need random text in the style of a Philosopher, do you know of any packages that could help with that?

@DavidCarlisle Maybe. ;-)

hmm I say in my last answer I'll ping the maintainer of float and it bounces as unknown address...

Joseph Wright

@DavidCarlisle Well not updated in 16 years so not surprising!

10:04 AM

@JosephWright tracked him down though, I'll ask...

@JosephWright hmm I suppose it is wrong to think of dates starting with "2" as "not that long ago"

Is it usual that running tlmgr update --all would result in "forcibly removed" packages? This keeps happening recently. I am on OS X (MacTeX).

Then on the next run I see skipping forcibly removed package messages.

@Szabolcs happens sometimes but I haven't noticed any recently (but I don't always look at the messages) today's update just updated 19 with no removals, is your texlive mirror reliable?

update to plain today?

OT question for native English speakers. I'm translating some Danish into English. Does this make sense in English: "Personal enquiry at the informationdesk in ..."

11:35 AM

@daleif "informationdesk" sounds very non-English.

@wilx what would you call it (two words?)

wilx

@daleif Yeah.

@wilx done

Joseph Wright

11:54 AM

@Szabolcs Can happen if there's an error, e.g. if you've got a file open and it can't be replaced

12:54 PM

@egreg sideways table, yes but fix in float or rotating?

@daleif information desk, but what is .... as "Personal enquiry at the information desk in" sounds a bit odd, perhaps "Personal enquiries should be made at the information desk in..." if that is the intended meaning

@DavidCarlisle Neither. :-)

@DavidCarlisle Possibly a fix in rotating for disallowing [H]

@egreg well \LaTeXError{don't use H} would be OK as an implementation

@DavidCarlisle I just added an answer where the disappearance is explained. I see no sensible way for solving the problem other than disallowing [H]: changing what float does at \end{<env>} would be quite difficult. And probably useless in this case.

1:16 PM

@DavidCarlisle thanks, we could not find any good formulations that soundes correct to us.

1:26 PM

I just got this:

! Package xkeyval Error: `width' undefined in families `Gin'.

See the xkeyval package documentation for explanation.
Type  H <return>  for immediate help.
 ...

l.96 \setkeys{Gin}{width=.85\textwidth}

Is this possibly a fallout from latest changes?

Never mind. This is my (pandoc template) problem.

2:32 PM

@AlanMunn -- me too! (are you familiar with the hoffnung music festivals? i think you'd enjoy those; they deconstruct in a somewhat different way, but often delightfully warped.)

Alan Munn

@barbarabeeton I'm glad you liked it. No, I don't know the Hoffnung festivals. I just did a search on youtube though. Looks like fun.

Joseph Wright

5:59 PM

@StefanKottwitz Probably, though they also suggest at least some of it is due to hits being missed by WordPress/JetPack (e.g. what look like legit requests)

@StefanKottwitz Do my best: may have to look at paying for some additional stuff in this area

6:31 PM

@CarLaTeX As you know, I'm Windoze impaired: can you confirm the problem at tex.stackexchange.com/questions/351207/…;?

6:50 PM

@egreg I'll check as soon as I arrive at home (I'm on the bus now) but I have Windows 10...

7:34 PM

@egreg I'll confirm, also on Windows 10, if you type x or e you don't see anything, the letter appears after pressing enter...

@egreg ^^^ and my Java version is updated, if this can be of interest...

@DavidCarlisle BTW, I should have done something wrong installing Emacs, because if I type e I get this error:

! Undefined control sequence.
l.6     \egreg

? e
I cannot find emacs in the PATH.
No pages of output.

Hi guys. I would like to write the following:
$$
\begin{aligned}
\rho(X,Y)&=1\quad\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\text{ for some real }\alpha\text{ and }\beta\text{ with }\alpha>0\\
\rho(X,Y)&=-1\quad\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\text{ for some real }\alpha\text{ and }\beta\text{ with }\alpha<0.
\end{aligned}
$$
but I would like to have the conditions both on two lines;
$$
\begin{aligned}
\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\\
\text{ for some real }\alpha\text{ and }\beta\text{ with }\alpha>0

@CarLaTeX I doubt I've typed e to that prompt this century:-)

@DavidCarlisle :) maybe that happens because I switched for MiKTeX to TeXLive after having installed Emacs...

@ShaVuklia don't use $$ in latex:-) well you could put them in a \parbox[t]{5cm}{If and only...}, or I'd use \begin{align*} not $$\begin{aligned} and then split the condition using the split envionment

@CarLaTeX well is emacs in your path (as far as i know it isn't usually added to the path in windows, just a "runemacs" wrapper added to desktop

@CarLaTeX what happens if you type emacs in a cmd window

@DavidCarlisle Thank you, I'm going to try to use the 'split environment' in '\begin{align*}'

9:10 PM

% These variables specify the external program called for the
% interactive `e' option.  %d is replaced by the line number and %s by
% the current filename.  The default is specified at compile-time, and
% we let that stay in place since different platforms like different values.
%TEXEDIT = vi +%d '%s'                    % default for Unix
%TEXEDIT = texworks --position=+%d "%s"   % default for Windows
%MFEDIT = ${TEXEDIT}
%MPEDIT = ${TEXEDIT}

@DavidCarlisle The system tells me that the command is not recognized

@CarLaTeX you can set TEXEDIT to have the full path to emacs in texmf.cnf ^^^

@ShaVuklia if you paste in text with a newline a "fixed font" button appears nect to send, or actually you can just indent by four spaces but you can not type a newline using enter key as it sends

Sorry, but how did you get the code font?

@DavidCarlisle I'll try to mend it...

@CarLaTeX whatever you do, don't do as the comments in texmf.cnf suggest and set TEXEDIT to vi !

nect? next

9:15 PM

@DavidCarlisle :) to be politically correct I'll set it to texworks...

@CarLaTeX I'd never usually want an emacs to open as I always have one open, I used to run emacsserver and have that set to emacsclient, or run tex inside emacs via auctex

@CarLaTeX I just tried e (on windows/cygwin) and it put me in vi :(

@DavidCarlisle Oh no, if Paulo knew that! :)

@DavidCarlisle So this should work
text
I guess

@ShaVuklia yes

Test

Test
Test

But I need to add 4 spaces after the code too

But fixed font doens't do that

It only add 4 spaces at the beginning

That is weird, but at least I know how to write the code

so thank you!

9:22 PM

@ShaVuklia ? you shouldn't need spaces at the end?

Well look; the first line has four spaces at the beginning, the second at both sides:

Test
Test

Oh yea you're right

Something went wrong then before

@ShaVuklia naturally!

:)

One last question though;

I've got this now:

\begin{align*}
\rho(X,Y)&=1
\begin{split}
\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\\
\text{for some real $\alpha$ and $\beta$ with }\alpha>0,
\end{split}\\
\rho(X,Y)&=-1
\begin{split}
\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\\
\text{for some real $\alpha$ and $\beta$ with }\alpha<0.
\end{split}
\end{align*}

but the text isn't aligned properly, if you can see it

Oh wait I think I know how I can solve one part of the problem

\begin{align*}
\rho(X,Y)&=1&
\begin{split}
\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\\
\text{for some real $\alpha$ and $\beta$ with }\alpha>0,
\end{split}\\
\rho(X,Y)&=-1&
\begin{split}
\text{if and only if }\mathbb P(Y=\alpha X+\beta)=1\\
\text{for some real $\alpha$ and $\beta$ with }\alpha<0.
\end{split}
\end{align*}

Could someone only tell me how to get the first line on the right at the same hight as $\rho(X,Y)=1$?

10:03 PM

@ShaVuklia see, it's better to ask on site:-) (but please post full documents)

10:52 PM

@DavidCarlisle oh :(

@egreg oh no

@CarLaTeX: I got a few days at home from the university, I can help you with your arara issue.

@PauloCereda Blame the LaTeX team. ;-)
