10:20 AM

@PauloCereda They are already too many, why should they be awaiting more people?

David Carlisle

12:47 PM

@HarishKumar clearly you should stay indoors, too hot to go out at those temperatures.

Harish Kumar

1:04 PM

@DavidCarlisle Hot for people from England!

michal.h21

Hi all, interesting blogpost:

boolesrings.org/krautzberger/2014/11/28/…

egreg

@michal.h21 Does the author know about TeX4ht?

michal.h21

@HarishKumar it should be -3°C on Sunday morning in Prague :)

@egreg probably yes, but I am sure he didn't post any bug reports or other messages about any problems :(

tohecz

@michal.h21 you're in Prague?

michal.h21

@tohecz yes

tohecz

1:19 PM

@michal.h21 aha!

michal.h21

@tohecz I thought you know that :)

egreg

@michal.h21 Quite unusual. :P

tohecz

@michal.h21 well, yes ... somehow, but we've never spoke to each other here AFAIR :)

David Carlisle

@michal.h21 that's funny I just came off a skype call with Peter, and there he is mentioned in chat:-)

michal.h21

@egreg it was around here 10°C last weeks, so it was unusual hot for us

@tohecz I think we spoke about tex4ht once :)

tohecz

1:24 PM

@michal.h21 ah yeah, true

well, there's a guy here in Paris that wants to have a reasonable quality production-ready solution for putting articles online using HTML + MathML, having LaTeX as the source, so it was probably related to this project.

michal.h21

@DavidCarlisle :) I think I will leave a reply on his blog later¨

@tohecz yeah, probably. I think you are from Záběhlice, or some area around?

tohecz

@michal.h21 well, I'm from Jižák :)

michal.h21

@tohecz ah, I am from Lužiny, paneláky rocks! :)

tohecz

@michal.h21 12th floor rocks, I can watch planes landing on RWY 30 :)

michal.h21

@tohecz :) pretty much the same, Ruzyně is behind small hill

tohecz

1:37 PM

@michal.h21 well, for me, there's a fill just before the runway so I don' see the touchdown, but I see the planes like 5s before it: mapy.cz/s/et7K

Harish Kumar

@michal.h21 Eh! I started shivering by that very thought.

michal.h21

@HarishKumar yeah, maybe I will have to find my winter jacket :)

@HarishKumar I suppose that you don't want to live in this beautiful village in Bohemian Forest:

Horská Kvilda

Horská Kvilda (German: Innergefild) is a village and municipality (obec) in Klatovy District in the Plzeň Region of the Czech Republic. The municipality covers an area of 29.91 square kilometres (11.55 sq mi), and has a population of 68. Horská Kvilda lies approximately 43 kilometres (27 mi) south-east of Klatovy, 78 km (48 mi) south of Plzeň, and 130 km (81 mi) south-west of Prague. == Geography and Climate == Municipality Innergefild - Horská Kvilda lies on central plateau of Böhmerwald (Šumava) mountains at elevation of some 1045-1090 metres ASL (3430 - 3575 feet). This valley is often filled...

David Carlisle

2:50 PM

@egreg @michal.h21 yes he also knows a lot about mathjax (he's the project manager) but mostly what he knows about is the "interesting" files that authors send to publishers that defy all attempts to convert to anything. If you have documents that redefine \relax then most translators get a bit stressed (not to mention latex itself:-)

percusse

Interesting read trmm.net/Utah2014

David Carlisle

@percusse I'm sure that @PauloCereda will be happy to see that despite all the changes one constant is emacs

@percusse ignoring the point of the article that it's "stagnation" rather than constant excellence:-)

Gonzalo Medina

3:08 PM

Can someone please process the document in tex.stackexchange.com/a/214448/3954 and attach the resulting image to my answer?

Joseph Wright

@DavidCarlisle Problem is you can do much the same in Word except people expect that

Christian Hupfer

Good maen...

@GonzaloMedina: Why? :D

Joseph Wright

@DavidCarlisle To me rather misses the fact the most scientists can happily manage to mess up lots of different formats: all this semantic stuff is produced by people who do it as their job, not by end 'users'

Gonzalo Medina

@ChristianHupfer Because I am unable to do it myself from the machine I am using right now :)

Christian Hupfer

@GonzaloMedina: In a minute it will be there ;-)

Gonzalo Medina

3:11 PM

@ChristianHupfer Thanks.

Christian Hupfer

@GonzaloMedina: Done y de nada ;-)

David Carlisle

@JosephWright yes I do think that publishers think that latex encourages bad input files because they get bad input files in latex. as you say if everyone switched to some other format they would get bad newMl documents instead. It's all the users fault

Joseph Wright

@DavidCarlisle Remember I work in an area where Word is more-or-less required, and I see all sorts of oddities. (I was reading a paper yesterday where they meant 'beta' but had used Ezsett, which was perhaps understandable 20 years ago but not today.)

tohecz

@DavidCarlisle LaTeX encourages bad input files from people never having received any LaTeX training.

Joseph Wright

@tohecz Partly

tohecz

3:20 PM

@JosephWright well: HTML encourages bad input files from people never having received any HTML training. The problem is that in HTML, it is much easier to ~~correct the input file~~ guess what the intention was.

Christian Hupfer

@tohecz: Which is strange, because by TeX.SX and other communities/online courses etc. it's so easy to write with LaTeX nowadays. When I remember the times roughly 20 years ago... DVI documents, README.TXT etc. it was not easy to learn LaTeX then

Joseph Wright

@tohecz Probably

tohecz

@ChristianHupfer you've had people having only changed \documentstyle to \documentclass during the last 20 years, and not doing any other change in coding during the period.

Joseph Wright

@tohecz My point is though that expected end users to write 'correct' code is a pipe-dream: if it works for them, they are unlikely to care if it archives correctly, etc.

tohecz

@JosephWright agreed. It's a mistake of Firefox that the (corrupted) HTML file which worked in IE3 doesn't work in FF31

Christian Hupfer

3:23 PM

@tohecz: Well, it might occur more frequently in university, by fossils of TeX/LaTeX :D

David Carlisle

@ChristianHupfer but modern latex is a nighmare for publishers if they just want it as an author input to ebooks or whatever. Simple markup of \section they can handle but if you have half a million lines of tex macros plotting functions and rendering them with tikz then processing that with anything other that tex gets harder and harder (I know there are svg back ends for tikz and it's not impossible, it's just not as easy as it was)

tohecz

@ChristianHupfer average scientific article author is in his 40s, which means that he's learned LaTeX more than 15 years ago.

David Carlisle

@tohecz youngsters. what do they know.

Joseph Wright

@DavidCarlisle Pictures though should always be send to the publisher as separate files, though, so that should avoid such things, no?

tohecz

@DavidCarlisle and again, you've got good TikZ code and bad TikZ code.

@JosephWright that's what I enforce, but then I receive this (gimme a minute):

Christian Hupfer

3:25 PM

@DavidCarlisle: I agree with that -- although I am no expert in TikZ, I admire it, but I see the difficulty to maintain such documents for journals... it's better to externalize graphics then.

David Carlisle

@JosephWright when does an equation become a commutative diagram become a tikz picture. The distinctions are blurred and wherever you draw the line, authors push at the boundaries.

tohecz

Joseph Wright

@DavidCarlisle Remember it's clear-cut for me: if I'd have to paste as a graphic into Word, it's a graphic

David Carlisle

@tohecz real input from real author?

tohecz

@DavidCarlisle after I've improved it a bit, yeah. This is the final code. (In other words, I gave up)

Christian Hupfer

3:27 PM

@tohecz: Even 15 years ago, the internet was still something like a kindergarten :D It was there, but not that evolved and if I dig out my first LaTeX documents, I would be ashamed -- I cannot show them to anyone (regarding the style of LaTeX, not regarding the output)

David Carlisle

@tohecz but I'm sure you could generate high quality html from that....

tohecz

David Carlisle

@tohecz what happened to self-adjoint in the lefthand box?

tohecz

@DavidCarlisle ah I haven't even noticed that one. I dunno. I blame this line :D

\text{\rm  \bf is \ not\  self\!-\!adjoint,\ }{{\hat{h}}}

David Carlisle

argggggggggggggggggg lf\!-\!adjoi is what happened

@tohecz I saw :(

tohecz

3:32 PM

you know, this one was the case where I said to myself: everyone who ever meets that beast will know that I'm not responsible for that. So I gave up.

Christian Hupfer

@tohecz: Ritz method of variation of Hamiltonian? Looks like perturbation theory

tohecz

@ChristianHupfer I don't know. I could link you the article, but my professionalism says to me that I shouldn't do it here and now.

Christian Hupfer

@tohecz: Oh my, I am not into that topic for ten years now... I just teach simple math: Polynomials, roots, factorization, derivatives, integrals... boring stuff

tohecz

@ChristianHupfer lol ok

If TikZ/XeLaTeX user has a spare minute: latex-community.org/forum/…

Christian Hupfer

@Johannes_B: Hello!

Johannes_B

Hello @christian

@ChristianHupfer Janitor and moderator. I look at unanswered questions, place unclear (or ...) in a plain text file for the next A the Unanswered, ask commentors to write answers. Asking still active members for clarification. Some commentors wrote answers and we could mke the list a bit shorter.

Christian Hupfer

@Johannes_B: I know, I read your Meta question yesterday...

Johannes_B

@ChristianHupfer Almost forgot this :-) No action so far.

Christian Hupfer

@Johannes_B: I upvoted, but I have not found a clear answer for it...

Johannes_B

4:03 PM

@ChristianHupfer I would suggest retagging, simple as that. And maybe renaming the tag {books} to {reference-books} (or something like that) as was suggested in the linked meta question.

Christian Hupfer

@Johannes_B: Retagging the questions or renaming the tag?

Johannes_B

@ChristianHupfer both

Christian Hupfer

@Johannes_B: Retagging is easy, but only mods can rename a tag, right?

Johannes_B

@ChristianHupfer I don't know. Maybe. I'll gladly do the retagging.

David Carlisle

@Johannes_B doesn't seem that surprising, how on earth can tikz know the size of the pstricks ?

Johannes_B

4:07 PM

@DavidCarlisle I guess i have less tikz foo then you. It was @StefanKottwitz suggestion.

Christian Hupfer

\foreach question uses [books]` rename to [reference-books] ...

For our tikz - obsessed users here :D

Johannes_B

@ChristianHupfer But some should be retagged to {book-design} and some to something completely different.

@DavidCarlisle The node will be as big as the content, which is a pspicture. At least i think so.

David Carlisle

@Johannes_B yes but I think it'll need some hint. I've never used externalize (or tikz really) but I have some mental model of what it's doing, and in that model at least it wouldn't know were pstricks is drawing, pstricks happens after latex has finished in teh dvi-postscript stage..

Christian Hupfer

@Johannes_B: Ok, then let's manually rename them... you go ahead and I will supervise you :-P

David Carlisle

@Johannes_B or rather: that node will be as big as tikz hopes the content will be when the dvi driver invoked by xetex after latex has finished draws some lines specified by the content.

Christian Hupfer

4:11 PM

I just got the refiner badge --- I am overwhelmed :D

Johannes_B

@DavidCarlisle So, simplest solution is to compile all in standalone ...

David Carlisle

@Johannes_B possibly. I've never used that either:-)

Johannes_B

@DavidCarlisle Ok, thanks for your advice.

Christian Hupfer

@DavidCarlisle: approx. 300 more rep than egreg this week, how? ;-)

Thomas E. Sturm has uploaded a new version of tcolorbox ... available tomorrow, I believe ;-)

David Carlisle

@ChristianHupfer knowing more about TeX I assume.

@ChristianHupfer we could ask @egreg

egreg

4:25 PM

@ChristianHupfer Unearned bounty and hyperactivity. ;-)

Christian Hupfer

@egreg: For sure ;-)

David Carlisle

@ChristianHupfer oy

Christian Hupfer

@DavidCarlisle: It was pure irony, sorry ... or say a false friend... If a German says "Sicher -- for sure!" ... it's meant ironically

David Carlisle

@ChristianHupfer but @egreg meant it:-)

Christian Hupfer

@DavidCarlisle: Yes, for sure he meant it :D

egreg

4:29 PM

@ChristianHupfer @DavidCarlisle's bounties are always unearned.

Johannes_B

@DavidCarlisle Seems the OP doesn't want to share information. chat.stackexchange.com/rooms/19014/…

@ChristianHupfer Can you name a single reference, where something like this is done? golatex.de/viewtopic,p,66361.html#66361

David Carlisle

@egreg pernacchia

Johannes_B

@ChristianHupfer How did you handle the introduction of new variables and stuff like that?

Christian Hupfer

@Johannes_B: Calm down, give me some seconds to switch to golatex :D

@Johannes_B: In my point of view, there should not be (much) text in an equation, rather an equation number and some explanatory text referring to that equation (line). If really necessary, an \intertext could help, but very scarcely applied

Q: tool to suggest index references

Is there a tool that will read through the existing index entries and then search through the document for additional locations where index words/phrases are used?

indexing

Johannes_B

@ChristianHupfer Introducing (explaining) the variables in the text?

I should ask @egreg. He teaches math at university level. :-)

Christian Hupfer

4:37 PM

@Johannes_B: Yes, I teach math for pupils only... you"re so mean :(((((((((((

egreg

@Johannes_B I find the practice of describing the variables in equations an insult to the reader.

Johannes_B

@ChristianHupfer ooh, sorry. The thing i wonder is, where do they get the idea?

Christian Hupfer

@Johannes_B: for the first time @egreg and I have the same opinion :D

Johannes_B

@egreg Thanks, exactly opinion. That is the reason i starred this message.

@ChristianHupfer I think everybody with a decent common sense should come to this conclusion after five minutes.

Christian Hupfer

@Johannes_B: Yes, where's the problem now? I said, I would explain them in a text (most likely following) the equation in the next paragraph

Johannes_B

4:42 PM

@ChristianHupfer There is no problem. Other people are doing it different and i want to know why. I thought you might have an idea where they get stuff like that.

Christian Hupfer

@Johannes_B: I did not teach this :D

egreg

@ChristianHupfer The typical E=mc^2 followed by "E=energy", "m=mass", "c=speed of light" means that we don't trust readers to understand what they're reading. Besides, what "energy" and "mass" is the author talking about? Saying just "energy" is completely meaningless.

@ChristianHupfer Or that we want they just read the formulas, because the accompanying text is rubbish filler.

Christian Hupfer

@egreg: We operate on two different levels of education/audience of some work sheet/paper/journal... on my (low-level) education needs, I have to introduce concepts/terms in a descriptive style, since my pupils/student never heard a specific term before

Johannes_B

@ChristianHupfer But you can introduce the mass m and three minutes later specify to be m_a (mass of a). That should do no harm?

Christian Hupfer

@Johannes_B: On school-level-education?

Johannes_B

4:56 PM

@ChristianHupfer Which age?

Christian Hupfer

@Johannes_B From 16 to 19 years ... Berufliches Gymnasium

Johannes_B

@ChristianHupfer How do you teach momentum and

    \begin{align} p &= p_1 + p_2 \\ &= m_1 v_1 + m_2 v_2\,. \end{align}

@ChristianHupfer This is the specification i am talking about.

Christian Hupfer

@Johannes_B: It's difficult. More than two indexed quantities is like a huge mountain most pupils can climb to reach the summit. You have to do many steps for this. And if you use a vector, everything is lost :D

Johannes_B

@ChristianHupfer Really? I went to school in Sachsen-Anhalt. That was basic stuff.

@ChristianHupfer when are vectors introduced? 8th grade?

Christian Hupfer

@Johannes_B: Our pupils come from Realschule... they will get their Abitur in three years on our BG, in most cases, they've never heard of a vector before, because they have NWA ... most times taught by a teacher with knowledge in Biology or Chemistry, but not on Physics, so they lack Physics knowledge...and as a Physics teacher you have to start from the beginning, most times

Johannes_B

5:05 PM

@ChristianHupfer That is not on the Lehrplan in Realschulen?

@ChristianHupfer I am a bit shocked.

@ChristianHupfer So, yours is a special case.

Christian Hupfer

@Johannes_B: It's a problem which has manifested for, say, 15 years now...., in Baden-Württemberg

Johannes_B

@ChristianHupfer There was no separation anymore between basic (grund) and advanced (Leistungs) course in SA. Lessons were at advanced niveua (for sure) tests were basic.

Christian Hupfer

@Johannes_B: Grund- und Leistungskurse were better, in my point of view.

Johannes_B

@christian chemistry LK. A problem that took the whole class half an hour could be done by the 5 people with an interest in chemistry in 3 minutes. And we were idle the rest of the time.

Das kann doch wohl nicht sein. Da könnt ich mich schoone widder offregen.

@JosephWright Can you please have a look at the answers column of tex.stackexchange.com/users/45805/faouzi-bellalouna?

David Carlisle

5:20 PM

@tohecz "people" in this context means a person at a given time presumably since we don't have that many users on tex.sx do we?

@Johannes_B: I definitely helped 52k people.... /irony off

Johannes_B

@tohecz It is rather »my posts got clicked 12k times«, did i understand this correctly? Haven't finished reading yet, so many distractions.

tohecz

@Johannes_B well, yes

Johannes_B

@tohecz Alsways glad to help the google bots. Nice guys. Doing a lot of work to help others.

Christian Hupfer

@tohecz: Is there a query to detect how many links one has shared? :D

tohecz

@ChristianHupfer I dunno

Christian Hupfer

5:33 PM

@tohecz: Feel encouraged to do so... :-P

tohecz

Just a disclaimer: the query I use is not official! I doesn't treat closures, deletions, ...

Johannes_B

On Math.SE (where I have access to 10K tools), 41.5% of anonymous feedback is negative: those visitors explicitly said the content was not helpful, but are counted as "helped" anyway. Raff

@Johannes_B and that's only one shit about the shit.

Johannes_B

@tohecz I see the arguments and i agree. This is smurf.

tohecz

anyways, gotta go, bye

Christian Hupfer

5:40 PM

@tohecz: Bye

@Johannes_B: Why is Math.SE so different?

Johannes_B

@tohecz bye.

@ChristianHupfer All SE sites are different to our community.

Christian Hupfer

@Johannes_B: Regarding the behaviour of the members?

Johannes_B

@ChristianHupfer I haveseen posts on cooking.se that simply said -> it wasn't helpful. I don't know why people have the urge to express there unhappiness.

@ChristianHupfer TeX/LaTeX is a clear field, everything is documented and since it is a macro language, you can do something new and add the explanation (documentation) to the answer.

Christian Hupfer

@Johannes_B: Math is a clear field (by far clearer than Physics! :D),so I just can't imagine that there're so many trolls there on Math.SE....

Johannes_B

@tohecz 116 items on the {books} list, i clicked all of them. Janitorial work is not helping 116 times.

Christian Hupfer

5:50 PM

@Johannes_B: Cooking.SE is a good point... I have to prepare the meal

Johannes_B

@ChristianHupfer Whats on the menu?

Christian Hupfer

@Johannes_B: Something very 'simple' ... Spaghetti Bolognese...

Johannes_B

@ChristianHupfer Mjam. Lasst es euch schmecken.

egreg

6:39 PM

@ChristianHupfer The sauce is “alla bolognese”. Spaghetti are surely not typical pasta from Bologna. Just for the sake of precision.

Johannes_B

6:50 PM

@egreg There will never be any patching mechanism for xparse-defined macros in the future?

David Carlisle

@Johannes_B why? xparse allows you to specify an interface for an underlying function. If you want a new interface just declare a new one. if you want different underlying functionality, patch the underlying command

Johannes_B

@DavidCarlisle Sounds reasonable.

Q: Syntax highlighting for LaTeX3?

Two years ago, @YiannisLazarides asked if Color coding of LaTeX3 code could be added to the syntax highlighter of TeX.SE. With posts using LaTeX3 code becoming be more and more frequent I would like to propose to re-open the request for some way to indicate LaTeX3 code and make it more readable...

feature-request syntax-highlighting latex3

David Carlisle

7:47 PM

@Werner it's easy enough to do just change the regex for latex so _ and : are treated like a-z but when I looked back then it seemed like a lot of bureaucracy to push it to google and then back to sx

Iplodman

@DavidCarlisle My antisocial media ;P

(An older version.)

David Carlisle

code.google.com/p/google-code-prettify/source/browse/trunk/src/…

@Werner a copy of that with [a-zA-Z_:] on line 35 would go a long way to doing the right thing.

Werner

@DavidCarlisle I'm unfamiliar with the requirements/implementation, but would that also change the way _ and : are implemented elsewhere - outside of control sequences?

The reason I'm asking is because people mix LaTeX 2e and LaTeX3 as we're in a perpetual transition between the two...

David Carlisle

@Werner probably not (but untested of course) it's just the keyword match

@Werner yes if you want combined then you want ` [a-zA-Z_:@] ` but it would have to be a separate language not an in place update or \sum_n would do the wrong thing

Werner

@DavidCarlisle So there's probably no combined LaTeX 2e + 3 syntax highlighting possible... in general.

David Carlisle

8:01 PM

@Werner I don't think so \sum_x is 3 tokens in latex2e and 1 token in l3, and with a regex you can't do the context sensitive grammar needed to spot you are in an l3 region

Werner

@DavidCarlisle Yes. I wonder whether that potentially answer the meta question. Somewhat. That yes, one can write that language... but there would be conflicting benefits.

David Carlisle

@Werner so if a latex3 language got in to google prettify you'd have to put a magic <!-- lang:latex3 .> comment (or whatever the syntax is) on tex.sx to force a code block to use l3 highlighting

Werner

@DavidCarlisle 

David Carlisle

@Werner yes that

8:47 PM

@Johannes_B It's surely possible to define one.

Manuel

9:18 PM

I asked before, but here I'm again. Wouldn't it be possible to redefine \ (primitive space) so that in contexts where we want to write to the terminal we can do some \string\command\ with a following space rather than some \string\other\space text. Is it possible to “test” for the last penalty or something like that and expand to \space in certain contexts or \ in case we are on normal text?

egreg

@Manuel No, unless one detaches \typeout from the standard \write.

David Carlisle

@Manuel no testing needed, just add \let\ \space locally in a patched definition of \typeout etc.

\g@addto@macro\set@display@protect{\et\ \space} makes \ a space whenever \protect is set up to write to files. It might possibly not break something;-) @Manuel

egreg

@DavidCarlisle Possibly. ;-)

@egreg sorry, my mistake

@David: @Werner's Portuguese is better than yours. :)

Werner

@PauloCereda Google Translate FTW!

Hope everyone has been having a tranquil Stoic Week 2014.

Back from a piano practice!

cfr

@tohecz Did you play Stoically?

tohecz

@cfr if "stoically" means "as loud as the piano managed" then yes :P

cfr

10:35 PM

@tohecz Probably: you didn't get distressed that the piano wouldn't play louder...

So you didn't rail against the order of the universe and respected the divine harmony of... of whatever.

tohecz

@cfr divine harmony of Claude Bolling you mean? :)

cfr

@tohecz Sure. I'm sure Epictetus would agree?

tohecz

@cfr sure, whoever he is

cfr

@tohecz Ancient Greek guy.

btw, I think that this one is worth 5 minutes of time:

egreg

10:42 PM

@tohecz Not more that 42 seconds.

tohecz

@egreg whatever you think

egreg

@tohecz Don't you know Epictetus? Or Seneca, a famous Roman stoic?

tohecz

@egreg It's been a long time since I've had school lessons on antic philosophy. I of course do know stoicism.

egreg

@tohecz Seneca was Nero's teacher; they had some small problems with each other afterwards. ;-)

tohecz

@egreg lol

10:50 PM

@tohecz @egreg's time is too precious? Definitely 300. Although I would probably appreciate it more if I weren't playing it extremely quietly through laptop speakers with the cat crying for access to the teepee. Epictetus for you.

tohecz

@cfr he just likes things 3 ottavas up so he plays them 8x faster :)

@cfr thanks for the link

cfr

@egreg Socrates, Seneca, Hypatia... They always say too much thinking is bad for you...

egreg

@cfr I used cfr-lm in an answer a few minutes ago. No thinking: left that to you.

cfr

@egreg The OSF one? I saw that.

The thing with Hypatia was especially nasty...

I don't even understand how you lynch somebody with shells - why shells?

@PauloCereda favouritism from Google. I should complain. @Werner

Werner

@DavidCarlisle Well, if you'd spend more time working on the Interwebz and less time answer (bounty) questions here, I think your translations would improve.

David Carlisle

@Werner I suppose I should think what I'm going to say at uktug tromorrow

Werner

@DavidCarlisle You don't have a topic yet?

David Carlisle

@PauloCereda maybe we should both give our UKTUG presentations in Portuguese

@Werner I have a vague idea of a topic I could do

Werner

@DavidCarlisle Please record this and post it online where we can all see the outcome...

@DavidCarlisle I assume this will be a secret until 2pm tomorrow then.
