I found a conflict between bm an etoolbox because later one redefines \@@end. It happens when it patches \enddocument command. Code from etoolbox: \patchcmd\enddocument {\deadcycles} {\let\AfterEndDocument\@firstofone \@afterenddocumenthook \deadcycles} {} {\let\etb@@end\@@end ...

etoolbox

@DavidCarlisle ^^^ Thoughts?

I could I guess add the redefinition of \@@end to \enddocument but if the latter is 'non-standard' that could be risky

David Carlisle

09:16

@JosephWright of course redefining \@@end is bad form really, the point of the @@ convention is that it's the original definition, probably I wouldn't change anything, it would just fomalise the practice rather than just saying etoolbox does it because it always did. It's just bad luck really bm doesn't need \@@end of course any non expandable token would have done:-)

@JosephWright haven't checked but \protected\def\@@end.... in etoolbox might be enough..

Joseph Wright

@DavidCarlisle No, though of that

David Carlisle

@JosephWright shame:-)

Joseph Wright

@DavidCarlisle You've got an f-type expansion going on (more-or-less: \afterassignment)

David Carlisle

@JosephWright oh yes, good stuff in bm really. I enjoyed that one:-)

Joseph Wright

@DavidCarlisle OK, perhaps plan B is to patch \deadcycles: I'm pretty sure all of the possible redefinitions will somewhere retain \deadcycles\z@\@@end

@DavidCarlisle I'll check through TL later on

Q: How do you write Munkre's topology T?

In James Munkres' classic topology textbook, he writes a topology T using a typeface I am unfamiliar with. I tried looking it up using detexify and checking commonly used character sets but the closest I could find was a capital fraktur I.

David Carlisle

@JosephWright that sounds even scarier, you mean if you have a custom trial OR and set \deadcycles locally some etoolbox hook runs?

Johannes_B

There was a question yesterday evening about mathspec and its strange behaviour when amsmath is requested. I think it was by user mhchem. Is it deleted, or am i just to dumb to find it?

A: Package incompatibilites: etoolbox, hyperref, and bm, standalone?

(Martin has posted an answer, but there is a bit more to this!) The problem arises due to an issue with the definition of \@@end. This is where the LaTeX kernel stores the TeX \end primitive (so that \end can be reused for environments). The bm package does various tests for \@@end which rely on ...

Johannes_B

@yo' Does that happen if the OP confirm the dupe directly? As announced a few days back on a meta Q?

yo'

@Johannes_B yes. This needs some work. But I gave up with that one.

Joseph Wright

09:31

@DavidCarlisle Oh

David Carlisle

@JosephWright I was searching for \deadcycles .....

Joseph Wright

@DavidCarlisle :-)

Johannes_B

@yo' This question here about the T? Or what do you mean?

yo'

@Johannes_B no, the new "quick duplicate thingy"

Johannes_B

@yo' The community is a bit confusing, imho.

@Johannes_B moreover, it not at all clear how it got there.

A: New UI encourages askers to confirm or dispute duplicate votes

The implementation of this idea is wonderful. However I have two suggestions. As OP approves the dupe vote, why attribute it to the Community User? It could be attributed to OP and his/her name should be placed in the blue rectangle, the same rectangle in which his/her name appears when (s)he c...

@Shog9 Well, they do have a completely assymetric binding close vote on their questions now. If you paint stripes on a horse, he doesn't become a zebra. He's just a horse with stripes. — yo' Mar 10 at 23:48

Johannes_B

@yo' Complicated discussion.

yo'

@Johannes_B yeah, because Shog9 (needed to say, I like him in general) doesn't see that what they did is really stupid in this case.

David Carlisle

@JosephWright so on github can you @ ping any github user simply with @ or did you add me to the cc explicitly elsewhere?

yo'

09:50

@DavidCarlisle just try it. I think on GitHub all pings get auto-linked (not like here, where you never know).

David Carlisle

@yo' you mean make an issue on one of my packages and randomly ping some gh user then mail and ask if they got it?

yo'

what is your name there? I can try it :D

Joseph Wright

@DavidCarlisle Just have to put @<username> in a comment

yo'

@DavidCarlisle or you can try it, my nickname is tohecz :)

Joseph Wright

@DavidCarlisle You only get auto-complete if the user has already been involved in the repo, so I had to type in your username by hand

David Carlisle

09:53

@JosephWright Oh OK thanks

yo'

@JosephWright needed to say, much more intuitive than SE :)

Joseph Wright

@yo' Well the logic here is that SE is not really meant for extended discussion, whereas that's quite reasonable on GitHub

yo'

@JosephWright yeah, but for instance the fact that you can ping a user that edited your post, but his name is not auto-completed? Completely ridiculous

David Carlisle

@JosephWright I think bm could do \outer\def\bm@end{\noexpand\noexpand\@@end} but I'd need to check that is safe in all possible expansion paths

Q: biblatex-ieee ignores protection for capital letters in title

since the last update (v1.1k) of the biblatex-ieee package the protection of capital letters for the whole title doesn't work anymore. I am using misc as entrytype and I want to keep the whole title as it is by using {{Title...}}. @MISC{bibkey, author = {D. Duck}, title = {{Skriptum ...

Another one for me, but isn't this an out-and-out bug report?

yo'

10:30

@JosephWright it is I think.

@DavidCarlisle \outer ?!

egreg

@yo' It's so that an error is issued rather than swallowing the entire document from the point of invalid input on.

Joseph Wright

@DavidCarlisle OK, etoolbox bug fixed, next for biblatex-ieee :-)

daleif

10:55

anyone know if pdfplots can be instructed to drop or ignore datapoints? A student came by with a plot from matlab2tikz that would not compile. Turned out it had generated 150000 lines of data and tikz conf (LaTeX ran out of memory). I asked him to try and redo his matlab programme so that it output less points. But now I'm wondering if there is something build in for this kind of thing (haven't been through the manual yet)

David Carlisle

@yo' Only time I have ever used it (my only other involvement with outer was removing it from the latex definitions of \newif etc:-)

@JosephWright aren't you glad you took over maintenance:-)

Joseph Wright

@DavidCarlisle Oh yes

@daleif See each nth point perhaps

@DavidCarlisle I also have github.com/josephwright/etoolbox/issues/2 to deal with, but my feeling here is WONTFIX

yo'

@JosephWright I'm not sure what he's after?

Joseph Wright

@yo' To know if something is blank after one expansion, I think, but etoolbox doesn't really do 'no, one, two, ... expansions'

yo'

@JosephWright yeah, that would be my opinion as well.

Joseph Wright

11:05

@yo' I have to watch that I stick to what PL was aiming for when he wrote the package

David Carlisle

@JosephWright yes too weird to control number of expansions, especially for testing with ifvoid

Joseph Wright

@DavidCarlisle Quite

Alan Munn

@daleif There's an each nth point={} key that can act as a filter on x values when plotting. I don't know if it would be helpful for this case.

Joseph Wright

@AlanMunn Same here: I use if for visual reasons but the data still have to be read

Alan Munn

@JosephWright Yes, I agree. @daleif your initial suggestion to the student is probably the better one. Matlab can certainly reduce its output more easily.

@JosephWright Sorry I now see you already said exactly that.

daleif

11:12

@AlanMunn Exactly, I hardly ever use pdfplots, how can I set each nth point globally?

Joseph Wright

@daleif \pgfplostsset{ ... } in the preamble

@daleif Like any other setting :-)

Paulo Cereda

So I had my tea yesterday, it was very good! :)

daleif

hmm, even with \pgfplotsset{
each nth point={1000},
}
I still run out of memory at the same place

@PauloCereda yesterday?

Joseph Wright

@daleif Like I said, I use it for output but you've still got to read the data

Paulo Cereda

@daleif I bought me a box of Twinings, never tried it before. :)

daleif

11:15

@JosephWright right, so the main problem here is the massive amount of points added

Paulo Cereda

@daleif Hold on. :) @percusse: sir sir we need help! :)

daleif

@PauloCereda ahh, I've switched to special imports instead. Quite hard to get Puerh in normal shops.

Alan Munn

@daleif Yes, Puerh is a pretty special tea.

yo'

@AlanMunn but so good!

daleif

@AlanMunn but worth it. as well as high quality white and green tea

Alan Munn

Q: Immutable functions in latex3?

Anyways, I stick to Ahmad tea when I'm at home, and we use that one with the scouts too (you need to find it in a good discount though, because we need ~ 200 tea bags for the camp

Paulo Cereda

@daleif Cool! How much does it cost?

Joseph Wright

Could someone translate this into English :-)

Alan Munn

But now poor @PauloCereda having just discovered Twinings is going to get caught up in the tea arms race.

yo'

11:21

@JosephWright It's either too early in the morning or my brain is too little lambda.

Paulo Cereda

I googled this Pu-Erh tea and the prices I got (in BRL) were pretty scary.

Joseph Wright

@yo' I think it means 'How do I arrange \l_tmpb_seq to contain the result of applying some function to each element of \l_tmpa_seq?', but I'm not certain

daleif

@PauloCereda At lot of it is quite expensive. But when it is good quality tea, you can reuse the leaves several times, which brings down the price per cup significantly.

yo'

@PauloCereda the prices are scary in any currency.

Paulo Cereda

@daleif aah so the prices were correct then. :)

@yo' Oh no! :)

yo'

11:23

@daleif I love white teas for that, the 4-5th cup is the best, but the 7-8th can still be ok. I leave the first cup in the leaves only for ~25 seconds (Yes, I use stopwatch for the first couple cups! It's 25, 30, 35, 40 for the tea I drink)

daleif

@PauloCereda If you go for the compressed cakes that are both rare and have been aged for a long time, they are very expensive. Presumably used as currency at some point. I usually by them as small one portion cakes (or what evere they are called) or as loose leafs.

@yo' I usually go for a few minutes. But you are quite right.

Heard a story about when tea arrived in the UK at the royal courts. The royalty would drink the first infusion and then send the leaves away. Then the staff of course reused them and even brought them home. It is well known that the first infusion is not the best.

@yo' yellow tea is also quite interesting, but rather rare.

Paulo Cereda

@daleif cool! I need to learn more about tea!

daleif

@PauloCereda When the shop I by from still had a physical shop, I took a course. We learned about the six different types of tea. Very interesting.

@JosephWright Definitely a Python user from SO :) If you don't ask questions in this manner it gets closed and dismissed. As far as I understand s/he is asking how to construct dictionaries as in Python A = {'a':1,'b':2,...}. Then when you invoke A['a'] it would return 1. Basically a look up table.

In the first part of the question as far as I understand s/he has two arrays one for the key names (seq_b)and one for the values seq_aand he wants to assign sequence a to sequence b by processing the array a first from a function say adding 1 to every value

@daleif If you click on the small broken arrow on the left side of the comments it will take you to the previous linked comment. It was about filtering points in pgfplots.

@JosephWright Who are the other ones?

Joseph Wright

@percusse See madoko.net

@percusse Written by a chap called Daan Leijen

daleif

@percusse yes but points after what? I do not have access to the MatLab file. I just got a copy of the output from matlab2tikz

percusse

@daleif After filtering. If you have a million points every 1000ths will leave you with 1000.

@JosephWright Sounds Dutch

Joseph Wright

@percusse Yes

daleif

@percusse but as @JosephWright stated it still have to read all the lines of the file, so it still dies for some reason running out of memory. The entire file only have 150k lines.

Joseph Wright

12:48

@daleif Did you try LuaTeX?

daleif

@JosephWright no, but that seems to be able to process it. I never use any of the lua stuff

Joseph Wright

@daleif No, but as LuaTeX does dynamic memory allocation it can help for these cases

percusse

@daleif Whoa! Then just do the filtering in Matlab on the file. I used to that a lot. But then I switched to LuaTeX for everything anyways. There is no difference on the front end for pgfplots or other common packages.

Just a different button to compile

You can modify a script like this (first result out of my search)

mathworks.com/matlabcentral/answers/…

daleif

@percusse well there still seem to be a lot of differences given the number of questions on here. Which is one of the reason I usually don't use the lua stuff.

percusse

@daleif I think you tend to think that with LuaTeX you would be using a lot of Lua code but that is not the case. It's just another engine. It is true that you get strange nuances compared to PDFTeX but most of the times you won't even feel it except there is some overhead in the compilation speed.

But you get a lot of goodies like dynamic memory allocation and moar registers so on

daleif

12:55

@percusse hmm, interesting, it does compile with lualatex, but the resulting PDF does not at all look like the figures the student showed be from MatLab. I think some of the axis ranges are f'ed up. But well that is his problem.

Joseph Wright

@egreg I love those plain question from people who clearly don't really understand TeX!

percusse

@daleif :-) Exercise for the reader

egreg

@JosephWright Yes, very nice exercise in bad programming.

Joseph Wright

@daleif That's likely a pgfplots setting thing

@egreg Did you spot \global\newcount\containsnum%? What is it with \new... that makes people want to prefix them?

daleif

@percusse I will still stick to pdflatex, because it is well known, and I don't have to deal with strange interactions because someone forgot that this engine behaves that way...

@JosephWright Yes, that's very nice too! :)

guys is there a recommended way of referring online sources in bibliography without bibtex?

Paulo Cereda

@Phonon As long as you load the package which provides it, you will be fine, probably. :)

I always forget it. :P

@daleif A mix of markup?

daleif

@PauloCereda Something like that. Problem is that many of them does not parse say <div class="special"> xxx </div>, they leave xxx alone. Or only allow one level of HTML which is bad if for example you have a complicated table with lots of links in it (which are for the most part duplicates, which is why I'd like to write these pages in markdown instead)

barbara beeton

@egreg -- is the course for credit or not? have you any suggestions for faculty elsewhere regarding how to persuade the administration to allow such a course to be presented? (there seems to be a lot of resistance to such a course in very many places.)

Alan Munn

@barbarabeeton I can understand why.

egreg

@barbarabeeton Yes, it gives two credits (students need 60 per year). In the Italian system, some of the credits are reserved for “student's choice” and free courses like mine can be validated by the faculty.

barbara beeton

@AlanMunn -- reasons?

Joseph Wright

17:55

@egreg We've just moved to a new system ('NAM'): every course must be at least 20 credits (out of 120 for the year) :-(

egreg

@barbarabeeton They have to sign their presence and send the assigned homework. Only after this I certify they fully attended the course and they receive their credits.

Alan Munn

@barbarabeeton Well I guess in the same way I would be opposed to courses in how to use a stats package (as opposed to, e.g. a stats course that has such a component as part of the course.)

Joseph Wright

@egreg Undergrad or postgrad?

egreg

@JosephWright Undergrad

Paulo Cereda

I convinced my dad to use Computer Modern in Word, at least his documents have a better look. :)

Joseph Wright

17:56

@AlanMunn Makes sense, although we have some such things for postgrad students (they have to do 10 days per year of stuff as part of a PhD, so often a half-day training)

Alan Munn

@barbarabeeton But I'm aware that this is not really a reason...

@JosephWright Yes, I can see such a sort of 'professionalization' training component (as some call it) could include things like this.

barbara beeton

@AlanMunn -- well, philosophically, "techniques" are not "academic content", and i can understand that. but effective faculty do stress "methods" as part of their instruction. the first person i worked for at ams had been a student of emil artin, and he apparently stressed presentation methods in his graduate courses, so that his students would be effective teachers when they emerged with their degrees.

Joseph Wright

@barbarabeeton In a subject like mine, 'techniques' are pretty important :-)

Alan Munn

@barbarabeeton Just out of curiosity I searched for SPSS and MatLab in our course catalogue course descriptions. They turn up only in content based courses, rather than things like "Introduction to SPSS/MatLab" etc.

barbara beeton

with respect to tex (and possibly other tools), in the u.s. there seems to be a bias against presenting any instruction as part of formal course content. and certainly not separate credit courses.

Joseph Wright

18:03

@AlanMunn You don't have research-facing courses for these (for PhDs/postdocs/staff)?

@AlanMunn Not-for-credit ones, I mean

Alan Munn

@JosephWright There definitely are such courses, but they are not part of the regular curriculum, but offered independently.

Joseph Wright

@AlanMunn Ah, that's what I'd expect

@AlanMunn I think here BIO do something on SPSS as part of labs

barbara beeton

@AlanMunn -- that confirms my suspicions. the only parallel i can think of is the "english composition" requirement one faces as a freshman.

when i was a grad student, the only "instruction" one got regarding theses or dissertations was a written set of rules. of course, then the tools were typewriters and pen + india ink for diagrams.

Alan Munn

@JosephWright Yes, they are of varying quality...

yo'

18:49

@egreg sounds similar to our system. Our LaTeX course is 7 lectures 100 minutes each and 6 practical classes 100 minutes each. For 2 credits. Should be actually 3 ETSC (or how's the European thingy called), but it's only 2 because the guy sitting in the bureau is ... him.

egreg

@yo' No “practical classes”. For the usual bureaucratic reasons, the laboratories use Debian stable, so they have a very old TeX distribution. Asking them to install the “vanilla” TeX Live is hopeless.

yo'

@egreg can't you ... make students SSH to your computer? or ... let them link the distribution in any given location from your SFTP?

Faheem Mitha

@egreg backporting newer versions of the Debian TeX Live packages to stable is not hard.

egreg

@yo' Would you? ;-)

Faheem Mitha

And the TeX Live version in stable isn't all that old. In wheezy it is 2012.

yo'

18:56

@egreg well, if it were the major burden for not having a practice class, I would :)

egreg

@FaheemMitha Which is what I call not old, but terribly outdated.

yo'

but we've got only about 20-30 students on the course every year, half of whom are willing to install the newest TL on their notebook they bring.

Faheem Mitha

@egreg Terribly seems a bit of a strong word. Wasn't TeX frozen in 1986?

egreg

@FaheemMitha Yes, but packages aren't frozen; and several new features have appeared in pdfTeX, XeTeX and LuaTeX since mid 2012.

yo'

@egreg also AFAIK there're recent changes in beamer and biblatex (we know whom thanks to @Joseph) and in L3 as well.

(sorry, that bad joke is probably a follow-up of going shopping with my parents today :-) )

@PauloCereda The motorbike is more attractive.

yo'

@egreg motorbike from SP to Darmstadt? o.O

egreg

@yo' Why not?

Paulo Cereda

@yo' an aquatic one. :)

yo'

@PauloCereda ach so

barbara beeton

@PauloCereda -- very long snorkel.

egreg

Using Computer Modern for math with Libertine as main text font can take you before the Spanish Inquisition and you could be sentenced to the comfy chair. Be advised. — egreg 18 secs ago

@barbarabeeton I could hold my breath. :)

barbara beeton

@PauloCereda -- not for that long, i don't think. if you could, you'd be a fantastic pearl diver.

Paulo Cereda

@barbarabeeton :)

@barbarabeeton I could be a fantastic Perl programmer. :)

yo'

@barbarabeeton I like the idea of @Paulo snorkeling from -4000m just so that he can get to TUG

@PauloCereda I almost fell off my chair

Is there any list of common situations in which "perhaps missing item" is not a missing item?

David Carlisle

21:57

@yo' almost always?

So I gave up and mailed Frank about that here float question:-)

Stefan Kottwitz

@yo' Sure

yo'

@DavidCarlisle well, it happens only with a parbox in an fbox, AFAI see....

David Carlisle

@yo' ?

you mean this one? Something's wrong--perhaps a missing \item ?

Stefan Kottwitz

@yo' Try this: \begin{itemize} not a missing item \end{itemize}

David Carlisle

@StefanKottwitz but that is a missing \item

A: Using \item within \newcommand

Something's wrong--perhaps a missing \item Is a notorious error message in LaTeX, it is almost never caused by a missing \item. It is actually generated if you use \addvspace in horizontal mode. As you have not given any context all we can say is that whatever you passed in as argument #2 or #...

Stefan Kottwitz

22:02

@DavidCarlisle yo' did not mention it with backslash :-)

but the message for \begin{itemize} a missing \item \end{itemize} sounds like a nice match

egreg

22:21

@StefanKottwitz Still I prefer this error:

! LaTeX Error: Missing \begin{document}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...

l.10 \begin{document}

?

David Carlisle

@egreg or..

! LaTeX Error: \begin{enumerate} on input line 10 ended by \end{enumerate}.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...

l.12 \end{enumerate}

Stefan Kottwitz

Another complete minimal example: H <return>

@UlrikeFischer: Hi Ulrike! Thanks for the great chess package! I'm preparing a keynote for a conference and had to include a match in one of my slides. :)

egreg

@PauloCereda A problem for a user of Math.SE: show that the function (on the natural numbers) $f(x)=\lceil\log_2(x+1)\rceil$ is surjective but not injective. There are 10 kinds of people: those who know the binary system and those who don't.

yo'

@DavidCarlisle actually, missing \par was the reason in my case (sorry, I was away for a while)

btw, is there any list of this error message paradoxa? (tell me, do you use the Latin pluralization suffix or do you stick with the English one for this word?)

David Carlisle

@yo' you could ask a question and @egreg and I could amuse our selves generating silly error messages:-) (while Frank sorts out that output routine question)

yo'

@DavidCarlisle lol

David Carlisle

@yo' paradoxes

yo'

@DavidCarlisle ok, thanks. (too late)

it's funny how people use for instance "indices" for the math notation but "indexes" for the lists at the end of some books

Paulo Cereda

23:25

@egreg ooh :)

David Carlisle

@yo' that's english for you;-)

yo'

@DavidCarlisle what?

David Carlisle

@yo' random syntactic constructs misused from random stolen laguage forms

yo'

@DavidCarlisle ah yeah

David Carlisle

23:53

google has such faith in my powers of organisation, just got an email:

yo'

@DavidCarlisle I think I don't understand the mail :D

Paulo Cereda

@DavidCarlisle Great, now Total eclipse of the heart is playing inside my head! Arrrrgghhhh!

yo'

@PauloCereda go heartless and you won't have these problems :D

David Carlisle

I'm worried I think I forgot to invite the sun and moon to that event, I hope they turn up anyway.
