your question isn't clear really what do you mean by "can only use \Sigma^{-1} ? that is the expected syntax, what syntax could you not use? ^{-1} syntax works in mathjax, whether the base is a letter like \Sigma or an explicit matrix. Unless you mean on this tex.stackexchange site in which case we don't use mathjax here. — David Carlisle 1 min ago

I am astonished every time by reactions like My question is simple, i don't need to post a minimal example.

9:59 AM

@egreg oy you were too late;-)

@Johannes_B Where this?

@DavidCarlisle :-)

@DavidCarlisle But I have no overfull. :P

@JosephWright No special place right now, it just came into my mind. :-)

@DavidCarlisle How's your voice going?

@egreg shameless badge hunting if you ask me:-)

@egreg comes and goes, the latter mostly

@JosephWright are you around today to do a final final build?

10:13 AM

@DavidCarlisle Yes: just want to know what the announcement status is

@DavidCarlisle Wet day: had hoped to go out for a ride, that is not going to happen :-(

@DavidCarlisle Have you decided about TUG2015?

@JosephWright No, I was trying to sort put a few things at work, but I've been off work most of last week and head too scrambled to think that far ahead:-) I'll probably go though

@DavidCarlisle Hope you make it :-)

@David: feeling better today?

@PauloCereda I'll survive:-)

@DavidCarlisle Guess who got the tick for the \XeTeXglyphs question? :P

@PauloCereda Just to make @DavidCarlisle feel better ^^^^^^^^

@egreg: So Éder scored for Italy? :)

10:41 AM

@PauloCereda Yes.

@ManuelKuehner Ask @davidCarlisle what he is using. ;-)

@DavidCarlisle ^^^^^^^

Manuel Kuehner

@DavidCarlisle I would be very happy and proud if you could share your hottest packages :). tex.stackexchange.com/questions/232007

@DavidCarlisle Hitting the gym now. Maybe see you later.

1:06 PM

@DavidCarlisle I just laughed about line 25 in nopageno.sty: % Another 4 token package...

1:21 PM

@Johannes_B :-)

@JosephWright How did that question not get closed? (tex.stackexchange.com/q/232007/2693)

All: Am building LaTeX2e release for CTAN

:-)

2:51 PM

Drafting release statement

3:15 PM

OK, draft written, one typo spotted the release so once build ctan is done I'll be ready to go

@JosephWright YEAH :-)

Back from the mass. :)

hi all, I would like to ask how can I move my cursor outside math environment in Texstudio. E.g. $ gafafas{my cursor be here} $ to $ gafafas ${my cursor be here}

@DuPhan I take it 'arrow keys' and/or 'click' are not suitable answers?

yes, I want to have a quicker way @JosephWright

3:23 PM

Can Superman beat Goku?

@DuPhan I'm not sure about key bindings, but you might navigate a lil' faster with ctrl + arrow.

oh, that is a good idea

i may change that combined key to Tab for example

@DuPhan Ducks are trustful. :)

thank you!

@DuPhan My pleasure, glad to be of service. :)

:)

3:27 PM

@Joseph is also a duck, so we have some sort of faction going on. :)

@Johannes is a penguin. :)

@PauloCereda Penguins don't use arrow keys.

@Johannes_B ooh

@DuPhan I use w or e or even W or E to move around. Or 5w :-)

maybe you use another editor right? e.g. vim, gedit,... but I am not familiar with them ^^

@PauloCereda Gotta get me something like this cafepress.com/mf/96832576/…

@DuPhan Penguins love vim.

3:45 PM

@Johannes_B :)

4:50 PM

@DavidCarlisle You have mail

@JosephWright thanks

@DavidCarlisle Feeling better? :)

barbara beeton

5:06 PM

@AlanMunn -- i shall have to make a note that if (when?) we actually meet, we should engage in a discussion about this. (i also, when answering the phone and someone asks to speak to barbara, automatically reply "this is she". it's probably a function of age and the fact that my mother was a school teacher.)

@AlanMunn -- i also prefer fowler to strunk & white.

5:18 PM

@FrankMittelbach See mail

Frank Mittelbach

@JosephWright just back home ... not yet seen anything :-)

6:01 PM

Yay cake!

Cake is gone. :(

6:26 PM

@barbarabeeton This is she and He is taller than I are two other cases in which the prescriptive rule doesn't really make any linguistic sense, I'm afraid.

@AlanMunn YAPM: knowyourmeme.com/memes/no-this-is-patrick :)

6:52 PM

@PauloCereda YAPM indeed.

7:04 PM

@AlanMunn Italian uses the indirect pronoun for both cases. Also French would. What about German?

@AlanMunn :)

@egreg A very long word I suppose. :)

@egreg By indirect, you mean the non-nominative form?

7:23 PM

@AlanMunn Yes

7:37 PM

@egreg In German you say Ich bin's (Ich bin es). I think in the comparative you also get the nominative case: Er ist größer als ich

@AlanMunn So English grammarians are right. ;-) At least in the second case.

@egreg For German. :)

@AlanMunn You're denying the origins of your language. :)

@egreg I blame the Normans. :)

@AlanMunn Call Robin Hood!

7:59 PM

@egreg Will I do? (being of the county of Nottingham)

8:11 PM

@AlanMunn ooh Johannes Passion!

@DavidCarlisle ooh Nottingham!

/singing the Men in Tights theme song

Curious problem. I renamed a LaTeX file, and the renamed file refuses to compile with the error:

! LaTeX Error: There's no line here to end.

I know this sounds improbable. Any debugging tips?

@FaheemMitha Remove auxiliary files, temp stuff, clean cache, etc. The usual.

@PauloCereda yes, I'm trying to remove anything with the name of the file. What does "clean cache" mean?

@FaheemMitha Things that are computed beforehand. Clean them. :)

@PauloCereda Before running the LaTeX file?

Not sure there is any such thing...

I've got a file called auto/smyt36.el. What does this do?

8:30 PM

@FaheemMitha Who knows, looks like emacs stuff.

@FaheemMitha Are you absolutely certain the file wasn't changed just before you renamed it? That would be my bet.

yo'

> I need draw in latex

@yo' Is this another work in your English Verbs without Inflection period?

yo'

@AlanMunn it's the title of a recent Q on the site

@AlanMunn Or Tom is interested in a new outfit. :)

yo'

8:40 PM

@PauloCereda you naughty you

@yo' <3

@yo' Not any more. :)

@AlanMunn I've repeated the copy several times. :-)

I'm going to try again now.

@FaheemMitha What do you mean? Every time you copy, the new copy doesn't run, but the original still runs?

@AlanMunn I've got a file smyt36.tex. This compiles fine.

If I do a cp smyt36.tex smyt37.tex, then smyt37.tex doesn't compile. It exits with an error.

I know it sounds ridiculous.

Nope, still getting that error.

8:52 PM

@FaheemMitha Even when you delete its .aux etc. files?

I've deleted everything in sight that could be related to either file, as far as I can tell.

@AlanMunn yes.

@FaheemMitha I.e., the original file's aux files.

@AlanMunn yes. I did a rm *smyt36*. Then I ran grep -R smyt36 and deleted any files that mentioned `smyt36.

@FaheemMitha And it then compiles without error?

@AlanMunn smyt36.tex still compiles without error, yes.

8:55 PM

@FaheemMitha Ok. I'm stumped.

@AlanMunn me too.

@FaheemMitha What line number in the file does the log show?

@AlanMunn you want the line number or the line itself?

@FaheemMitha Well the number itself isn't much help to me, but when you look at that part of the file is there anything going on there?

@FaheemMitha: compilation in command line?

9:00 PM

@AlanMunn Doesn't look like it. I'll paste it - one sec.

yes, I'm compiling using `pdflatex -shell-escape smyt37.tex`.

@PauloCereda ^^

@FaheemMitha The error is usually produced by a wrongly placed \\ command

@egreg yes, so I gathered by googling it. But can you think of any reason why it would give this error in a file that differs from another only in name?

@FaheemMitha Of course no.

@egreg ok

@FaheemMitha But the line (/usr/share/texlive/texmf-dist/fonts/tfm/adobe/ncntrsbk/pncb8t.tfm) looks very suspicious.

9:05 PM

Check encoding, zombie processes, file locking, diff, path... (sorry, on mobile)

@egreg Why?

@FaheemMitha That means you're inputting a tfm file, which should never happen.

@egreg oh

@FaheemMitha TeX loads tfm files in the background, without logging them.

@egreg oh

Ok, the rename isn't the issue. I copied it to /tmp without renaming, and got the same error.

So it is some file it is picking up in that directory.

Sigh. Debugging is a pain.

9:14 PM

@FaheemMitha Is the file a military secret?

A: Embedding Mercurial version control information in a TeX document

@egreg nope.

If you are asking whether I can strip it down and provide a MWE, probably.

Assuming I can't figure it out myself, of course.

I pine for the days of AI, when you can just tell a computer what to do.

Dammit, why couldn't I be living in the 24th century, when a robot will TeX things for you?

Ok, I think I've figured out the problem. The file is not under version control.

Yes, that was it.

I guess I should make my little macro thingy more intelligent.

The culprit is this:

4

The following one-liner, if placed in a LaTeX file, gives the Mercurial changeset identification hash. Substitute rev for node to get the local revision number. \input{"| hg log -v -l 1 \jobname.tex --template '{node}'"} For this to work, running LaTeX with the -shell-escape option is required...

If hg doesn't return anything, TeX seems to get upset. Don't know why, of course.

I think it is this box:

\setkomavar{firsthead}{%
\parbox{\linewidth}{\centering
\textbf{\jobname.tex} \input{"| hg log -v -l 1 \jobname.tex --template '{node} {date|isodate}'"}\\
\hspace{\textwidth}
\usekomavar{fromname}\\
\usekomavar{fromaddress}\\
\usekomavar*{phoneseparator}\usekomavar{phoneseparator}\usekomavar{fromphone}\\
\usekomavar*{emailseparator}\usekomavar{emailseparator}\usekomavar{fromemail}
}%
}

Without the hg input, this line is blank

\textbf{\jobname.tex} \input{"| hg log -v -l 1 \jobname.tex --template '{node} {date|isodate}'"}

And then I guess there is just a \\ on a line by itself. And then TeX gets upset.

Let me test that.

No, that doesn't make sense, because \textbf{\jobname.tex} is still there.

So, there is an eclectic group of people here, including some people from the UK.

Did anyone here know Tom Troscianko?

So, what would this return, if hg itself returns nothing?

\input{"| hg log -v -l 1 \jobname.tex --template '{node}  {date|isodate}'"}

9:56 PM

@AlanMunn Also an extra e.

@FaheemMitha True, but Apostrophes and e's doesn't sound so good. :)
