TeX, LaTeX and Friends

9:17 AM

has anyone heard from (or know another contact address for) Uwe Kern (xcolor@ukern.de) since about 2007?

@UlrikeFischer does he ever go to dante meetings? ^^

9:47 AM

@DavidCarlisle I never saw him (but I wasn't there very often). I also mailed him about some xcolor bug but never got an answer. The denic registration shows an address so one could try a real letter.

9:57 AM

@cfr Thanks for the insight about Arch, I might install it in a test machine for fun. :) I am overclocking my iMac at the moment, so I will be able to have lots of virtual machines. :)

@UlrikeFischer or I could add some code to color.cfg that patches xcolor on luatex.....

@DavidCarlisle The next colour package in line is zcolor? :)

10:12 AM

@PauloCereda I think the henryfordcolor.sty would be the best

@DavidCarlisle ooh

@PauloCereda "Any customer can have a car painted any colour that he wants so long as it is black."

@DavidCarlisle LOL

@DavidCarlisle Hm. Then you could probably also add patch for this xcolor bug groups.google.com/forum/#!topic/comp.text.tex/yFX7MccBvXY which can also be seen in this example:

\documentclass[]{article}
\usepackage{tikz}
\begin{document}

 abc
 \color{red} abc
 \normalcolor abc %
 \tikz\draw[->] (0,0) -- (1,0);
 abc
\end{document}

@UlrikeFischer sigh that's probably my fault. I regretted later making color pass things round using the driver specific \special strings rather than a unified format as used for input. It saved a bit of runtime but complicates pretty much everything else

@UlrikeFischer of course it's even more dubious to patch that in color.cfg, color.cfg is all about defaulting the back end driver option so adding code to define a luatex back end and selecting it is almost reasonable, but patching internal package commands a lot less so.

10:24 AM

@DavidCarlisle Should I try to contact him by letter and offer him that the latex team takes over in case he no longer wants to maintain the package? (More work for you if he accepts ... )

@UlrikeFischer well I just asked (by email to tex@) if he hasn't time could he let us update it now just for luatex (rather than take over) but if you could do something that would be good, thanks

10:47 AM

@DavidCarlisle I wrote a letter and will post it in the afternoon.

@UlrikeFischer thanks

11:50 AM

@DavidCarlisle No serial duck upvoting for @UlrikeFischer, it seems

@egreg SUCCESS!

:)

@egreg s/No/Well concealed/

12:18 PM

@barbarabeeton here is one for you: tex.stackexchange.com/q/308157/3929

@egreg sigh. I miss all the 9 at the start of the number. It will take me ages to get them back. Perhaps I should make a feature request to show the number in another base. base22 looks ok: 98H1.

@UlrikeFischer Another possibility is a downvote spree. :)

This sounds much @David-like. :)

@PauloCereda best to get the free mug first, then arrange the downvotes

@DavidCarlisle ooh there's a freebie?!

I cannot quite figure out what amsbook is doing wrong in its headers, even if textcase is loaded \uppercasenonmath{\chaptername} still comes out wrong

12:38 PM

@UlrikeFischer Yes, it will take some time also for me to get at having so nice 999 at the start.

@daleif @barbarabeeton amsbook does \uppercase\@xp{\chaptername}\enspace\thechapter} \uppercase isn't going to work here: needs to be \MakeUppercase (or textcase version to avoid math)

12:58 PM

@UlrikeFischer no need for that letter!

@DavidCarlisle 'Interesting' code

@JosephWright we could blame Frank (although it doesn't look his style:-)

@DavidCarlisle :-)

Copyright 1995, 199, 2004, 2009, 2015 American Mathematical Society.

Hmm, that's an old copyright

@JosephWright Heard from Uwe Kern, so hopefully that's one less package that we need to adopt

@DavidCarlisle Phew

1:00 PM

@JosephWright the second one is @egreg's contribution

@DavidCarlisle :-)

What have the Romans ever done for us

2

@DavidCarlisle Probably we'll need to write a proper LuaTeX driver for hyperref (mechanically at first). Did you notice some of HO's other packages also have driver code?

@JosephWright yes yes

Romanes eunt domus

@DavidCarlisle OK, I might look at some of this

@DavidCarlisle Need to also do l3build for testing all of TL!

1:03 PM

@JosephWright not sure I have much more time in next day or so, so I'd be tempted to push out what's there to ctan (as @UlrikeFischer hinted a miktex update is imminent) and then clean up the rest via normal updates, but I'm happy to let you have a pass over it first if you wish

@DavidCarlisle I meant in the course of things: for the present a CTAN update fixing the immediate issue is the best plan

@JosephWright OK I'll do an update tomorrow unless something turns up.

-- i've made a simpler file using amsart (which also applies automatic uppercasing). the complaint i get for that is
! Package inputenc Error: Keyboard character used is undefined
(inputenc) in inputencoding `utf8'.

@barbarabeeton well that's different, you can't uppercase it if it's not defined!

@DavidCarlisle -- i'm looking into the uppercasing, but most of the uppercased elements use \uppercasenonmath and that should be doing the right thing, i think.

1:10 PM

@barbarabeeton but \chapter escaped and uses \uppercase directly?

@DavidCarlisle Job for \tl_upper_case:n ;-)

@JosephWright does that work for Vietnamese in pdftex with \uhorn and friends?:-) can't remember where you ended up with that....

@DavidCarlisle Not at the moment: I went for 'T1 accents with pdfTeX, everyone else really should be using a Unicode engine'

@DavidCarlisle Still needs more users, of course

@barbarabeeton @barbarabeeton smaller mwe:

\documentclass{amsbook}
\usepackage[utf8]{vietnam}
\begin{document}
A
\uppercasenonmath{\chaptername}

B
\uppercase{\chaptername}

C
\MakeUppercase{\chaptername}
\end{document}

@JosephWright you'd get more users if it worked with pdftex:-) meanwhile pointlessly waiting for election results (although the conservatives not getting all three seats is less likely that Leicester winning the league)

1:16 PM

@DavidCarlisle -- and for me, that comes out correctly all uppercase. the character that disappears (in running heads -- had to extend the example) is áº. (hmmm. that seems to have been modified when i cut and pasted. i'm using emacs with mule utf-8 encoding.)

@DavidCarlisle It does work with pdfTeX, just not for every possible language covered by the LICR

@DavidCarlisle No council elections in my ward, just police/crime commissioner

@JosephWright they redrew all the ward boundaries round here so all seats are up for grabs again

@DavidCarlisle :-)

@daleif -- okay -- \uppercasenonmath simply disappears; \uppercase fails to uppercase the hooked u and o; \MakeUppercase does the right thing. before suggesting anything, will have to test to see what happens with math of various sorts. thanks.

@barbarabeeton if you want math to survive you need MakeTextUppercase from textcase (amsbook already looks for that and changes some definitions if it is there)

1:23 PM

@DavidCarlisle But strangely that only fixes \uppercase, \uppercasenonmath{\chaptername} is still empty

Hmm, I do not seem to know how \uppercasenomath is suppose to work

@daleif yes I can't see how it changes \uppercase one, since \show\uppercase says it's the primitive, will look later

@DavidCarlisle -- i've discovered another problem in my cutting-and-pasting. the mule-utf-8 emacs file encoding seems to not work properly; but the "ordinary" utf-8 apparently does. more to investigate ... trying again with corrected files.

2:00 PM

@DavidCarlisle OK. I put it into the bin.

@UlrikeFischer thanks for the offer though

@DavidCarlisle my pleasure. Perhaps you could ask Uwe Kern to allow to set options like "table" and load colors after the package -- this would reduce the option clash danger.

Hello, I am rusty on my LaTeX (haven't needed to use it in awhile). I know there was a package that would upload code by calling the script python.py or matlab.m. What package is that again?

2:22 PM

@dustin ??? what do you mean by upload here? if you just want to typeset code sections listings or minted are usual choices if you want syntax highlighting or verbatim if not

@DavidCarlisle I think I was able to do something like \include{name.py} and the script would be in LaTeX without copying an pasting. Been working in industry and not academia so I have forgotten so much.

@JosephWright, @DavidCarlisle, @egreg: ^^ success!

@PauloCereda :-)

@JosephWright Now, to Parallels! :)

@dustin yes as I say listings, minted or verbatim will all do that (with different command names of course)

2:46 PM

@JosephWright: now tell me how much RAM you have (expecting 64GB). :)

@PauloCereda 16 Gb: motherboard limit

@JosephWright Yay, I am in the club!

:)

@PauloCereda a biologically interesting statement

@DavidCarlisle Look at @Joseph's avatar. :)

Where does shell escape go in TeXworks when using latexmk?

$pdflatex=q/pdflatex $synctexoption --shell-escape %O %S/

This doesn't work.

2:54 PM

@dustin where exactly are you typing this?

@daleif this is in processing tools

@PauloCereda still a duck here

@dustin Each option has to be separate

@DavidCarlisle Yep, we are in the duck club. :)

@dustin so, in the texworks conf?

2:55 PM

@JosephWright I tried it on a separate line but that didn't work either.

Be back in a second need to log off and back on.

@David: Unless, of course, you tell me that Joseph is not a real duck. :)

@PauloCereda oh that's what you meant:-) I meant that you might want to check the UK english idiom "in the club" ;-) dictionary.cambridge.org/dictionary/english/in-the-club

@dustin remember most latex options can be passed directly onto latexmk

@DavidCarlisle HOLY COW

2:58 PM

@DavidCarlisle As far as I remember, the date is wrong: I contributed just after 201 AD

@JosephWright how did you upload the image

@dustin there is a big red upload button to the right of the text box where you enter comments:-)

@PauloCereda how did you upload that image?

3:00 PM

@JosephWright where does shell escape go in this instance?

@DavidCarlisle With a meta-upload button. :)

@PauloCereda phew, type hierarchy saves us from infinite recursion.

@DavidCarlisle Exactly! :) Or we could find a fixed point operator. :)

@dustin remove the $pdflatex line, and add $synctexoption and --shell-escape on separate lines. That ought to be enough

@daleif I want to add it without destroying the latexmk setup

3:04 PM

@PauloCereda I worked with Peter Aczel on non well founded set theory for a couple of years in a previous life

@dustin latexmk just passes -shell-escape on to pdflatex

@dustin do you want to make --shell-escape the default pdflatex behaviour?

@DavidCarlisle I do.

@dustin very brave!

@DavidCarlisle ooh :)

$ arara file

:)

3:08 PM

@dustin this seems to work fint in my test

$synctexoption

--shell-escape

$fullpathname

% arara: pdflatexmk
...

@David: don't you like using a tool for calling another tool which calls the engine? :) ^^

@PauloCereda well, would you run a document copied from the internet that looked like xii.tex if you had shell-escape on by default?

@daleif are you using latexmk with it?

@PauloCereda that's called emacs

@DavidCarlisle yes. :)

@DavidCarlisle boo

3:12 PM

@PauloCereda ducks are very trusting (that's why they are easy to catch....)

@DavidCarlisle awww <3

@DavidCarlisle: ^^

breeden

is there a way I can have my credit card automatically input for my tex prompts?

@breeden I will add this as a feature request. :)

breeden

Thank you :)

Can \input be used in \begin{minted}\end{minted}?

3:25 PM

@dustin \inputminted{csharp}{hello.cs}

@PauloCereda thanks.

@PauloCereda what is the first {csharp} referring to?

I cannot access ctan docs on my work network.

@dustin for sintax highlight. :) This line says it's a C# code being inserted.

@PauloCereda I keep getting missing endcsname inserted

! Missing \endcsname inserted.
<to be read again>
\let
l.157 \inputminted
{python}{geocode_mp_test.py}
?

@dustin I have no idea what's going on, sorry. :(

@PauloCereda me either, thanks.

3:50 PM

@dustin that sounds familar....

@dustin hm I was thinking of this but that's non letters in the language name, not the file name github.com/gpoore/minted/issues/111

@dustin really the error is like that with a line break after inputminted? that means tex died before it even read the arguments of the command

@DavidCarlisle I found a post answer by egreg and just re-entered the name and it worked.

@dustin I was, as I said, worked fine, filled in in a window like the one Joseph showed. Just added a new processing command and filled in hose options

@dustin I suppose he's posted so many answers, it's not that surprising that one turns out to be useful:-)

@DavidCarlisle even a blind squirrel gets a nut

@JosephWright @StefanKottwitz @clemens This is almost helpful. Do spammers get smarter?

@dustin Don't feed the trolls. ;-)

@egreg Just ducks. :) I appreciate cookies and Pringles. :)

@PauloCereda Or Cookie Monsters!

@PauloCereda Do you know Flat Beat by Mr. Oizo? You might like the music video.

6:00 PM

"Control sequence \latin already defined." That seems like a bad thing

Now to disable packages one by one till I find the conflict

Is there an easy way to tell what package is causeing the conflict?

@DavidCarlisle you are the expert on such things, right?

@Canageek -- if you're lucky, the conflict was reported while you're reading in a package. then you only have to look at the packages loaded earlier. best to check what's been read in by what's in the log -- lots of packages load others ... and the log reports them all, as well as where they were loaded from.

@barbarabeeton Happens right after I load siunitx, and the line number is my \begin{document}

| The current meaning is:
| \long macro:#1->#1

6:18 PM

@Canageek -- well, that's a bit of bad luck. are you, by any chance, a chemist? \latin is found in chemmacros.sty and chemstyle.sty. (also in liturg.sty, but i think that's unlikely.) grep is a good friend.

@barbarabeeton Yep, had just figured that out.

@barbarabeeton CHemmacros is fighting with achemso. Dammit. Guess I have to redo my whole document using mhchem?

@Canageek -- not a chemist. can only commiserate, not help.

@barbarabeeton Is there a way to tell those two packages to play nicely by any chance?

Well, first I'm going to update TeXLive, I'm multiple versions out of date on chemacros. About a year

Might be able to disable that part, if I'm not using it.

oh. oh damn. I'm on TeXLive 2014 it seems

@Canageek -- if you can figure out how the different instances of \latin are defined, you can decide which one is likely to be necessary, then load that package last, and before you do, \let\latin\relax. (if you're lucky, they'll be defined the same, so letting the first one \relax would be entirely harmless.) good luck.

7:30 PM

@clemens Hey. 1) Chemacros won't work with achemso and 2) Comments on your blog are broken. When I hit submit I get a download .php file popup.

Durrrr. Then I googled it and find that that question has not only already been asked, but I UPVOTED IT.

@Canageek I usually just stick \show\latin after each \usepackage in the preamble

@DavidCarlisle ....had I know I could do that, I would have.

8:14 PM

Question: At what point does Chemacros define chemprime?

Is that at begining of document by any chance?

\documentclass{article}

\show\chemprime

\usepackage{chemmacros}

\show\chemprime

\begin{document}

\show\chemprime


\end{document}

@Canageek undefined, undefined, defined, so yes

@DavidCarlisle Dammit. That makes it impossible to set up a glossary using \chemprime

@Canageek why?

@DavidCarlisle You define the glossary terms before the start of the document, so you can use abbeviations. I think I'll just stop using that, it was a pain anyway.

@Canageek you can always adjust the timing but here the macro is so simple, it's just \ensuremath {{}^{\prime }} you could just define it in advance if you need it

8:20 PM

@DavidCarlisle Then wouldn't chemamcros scream when it can't define it? Or would I undefine it right after I use it?

@Canageek yes but surely you can use an undefined command in your definition as long as its defined by time you use it can't you?

@DavidCarlisle It was giving errors. I wanted to redo that bit anyway, it wasn't giving the results I wanted.

@DavidCarlisle I had to redo where I was defining terms anyway, so whatever.

@Canageek if a package screams at me I usually go in with a knife and silence it:-)

8:45 PM

@DavidCarlisle Or thereupon declare it is a feature.
