TeX, LaTeX and Friends

12:00 AM

@DavidCarlisle I'm sorry, I can't locate the error. The document I'm pasting into already has ~80 errors or so already. The \the \relax thing is probably not why it can't compile I have now realized because the other references have those warnings as well. There are also plenty of this:
Undefined control sequence.
<argument> \@listctr

The encoding is set like this: \usepackage[utf8]{inputenc}

David Carlisle

@Pickett \@listctr is set in numbered lists like enumerate and bibliographies if they are numbered, to say what counter to use. But with TeX it's only ever worth looking at the first error its error recovery isn't designed to make a sensible document, just to get itself unstuck so everything after the first error is potentially misleading junk and any errors reported in it may be spurious.

@Pickett nah, it's not an encoding issue I suspect

Pickett

@DavidCarlisle The message at the top is "Error in main.tex (line 593): Misplaced \crcr.
\endtabular ->\crcr
\egroup \egroup $\egroup
l.593 Råde L. \and
Westergren B. (2004) \\
I can't figure out why you would want to use a tab mark
or \cr or \span just now. If something like a right brace
up above has ended a previous alignment prematurely,
you're probably due for more error messages, and you
might try typing `S' now just to see what is salvageable.

! Extra }, or forgotten \endgroup.
\endtabular ->\crcr \egroup

But that row is not my reference, and it is specifically my reference that makes it uncompilable.

Also I'm using an online service, ShareLatex, and I don't know if it changes the order of the error messages.

@egreg: campioni! :)

David Carlisle

so on line 593 there is an \end{tabular} that shouldn't be there, (or since I notice \and it may be a bad \author command which uses tabular internally I don't know where you are, but I'm in the UK and it's 1 in the morning so I can't be bothered to worry about it, get @PauloCereda to sort it out, it's a more civilized time in Brazil:-)

Pickett

@DavidCarlisle It's 2:25 here so I'll probably spend some time on it tomorrow instead. But thanks so much for your time.

Pickett

12:55 AM

I solved it now. It was because some other references that were not mine used "\and", when I replaced those it started working.

This is the most horrific graphic I've ever created, and it's going to be larger-than-life. Any suggestions?

obviously, these are split across many, many slides via overlays. It's a max of one box, one arrow, and a description.

@egreg: Re: Spacing in \chapter {title} -- That was what I thought I had said: that there is no difference -- but there is certainly a problem with the last parameter is optional as is the case with xstring.

egreg

7:23 AM

@PeterGrill \StrSubstitute{xstring}{i}{a} [\foo]\show\foo

Peter Grill

@egreg Hmmm... I thought I had read that somewhere, perhaps an earlier version of xstring?

Paulo Cereda

8:18 AM

@DavidCarlisle I woke up 15 minutes ago. It's 05:15 AM now. :)

hugovdberg

9:22 AM

@PauloCereda goodmorning :) it's 11:22 (am) here ;)

tohecz

9:49 AM

@PauloCereda it's 11:50, and my exam starts at 14:00

David Carlisle

@JosephWright plain doesn't set \newlinechar to `J does it?

Joseph Wright

@DavidCarlisle No, but try my demo with pdfTeX or LuaTeX

@DavidCarlisle Something is up somewhere

David Carlisle

@JosephWright oh I tried it with classic tex (which works like xetex)

Joseph Wright

@DavidCarlisle All very odd

David Carlisle

@JosephWright which means the pdf/lua tex behaviour seems wrong, newlinechar=-1 but ^^J works anyway

Joseph Wright

9:56 AM

@DavidCarlisle Might be defined behaviour of the binary: just checking

David Carlisle

@JosephWright oh no it'ls llike us having to use teh asci.tcx file in the test suite to get accented characters output as ^^ it is system dependent which characters print as themselves

Euryris

Easiest way to count sections in an environment? Tocloft right? Or is it worth building one manually? My goal is to determine the last section of my document without the use of a label

Joseph Wright

@DavidCarlisle OK, for LuaTeX I thought I'd seen something:

> Output to the terminal uses ^^ notation for the lower control range (c < 32), with the exception of ^^I, ^^J and ^^M. These are considered ‘safe’ and therefore printed as-is.

David Carlisle

@JosephWright which isn't a good choice really as it makes \newlinechar a bit pointless

Joseph Wright

@DavidCarlisle Can't see it in the pdfTeX docs, but you see the same with e.g. etex (which is of course pdfTeX), so I guess this is a deliberate but undocumented 'feature'

@DavidCarlisle Funny how we keep stumbling across these things while doing LaTeX3 work!

David Carlisle

10:00 AM

Note the ^^^^ you are refereed to a ticket with a bug from Bruno:-)

Joseph Wright

@DavidCarlisle Yes, saw that

@DavidCarlisle I'd been trying to remember how to trigger that last one

@DavidCarlisle XeTeX and LuaTeX also differ in handling exactly three ^ in a row, but at least that's deliberate!

David Carlisle

@JosephWright I suppose we should fork the thing in github fix them and ask them to pull the changes back how's your web/pascal/C++ foo?

Joseph Wright

@DavidCarlisle Erm, very limited

@DavidCarlisle Did you follow the trouble I had last time we asked for a XeTeX patch?

David Carlisle

@JosephWright excellent, you are hereby nominated as the local expert.

@JosephWright I vaguely remember some mail headers go by, I think that was in a period when I was auto-archiving latex mail:-)

Joseph Wright

11:29 AM

@DavidCarlisle Drat

@DavidCarlisle Could well be: I think responses at the time were from Will, Frank and Morten

egreg

11:39 AM

@GonzaloMedina Would you contribute to this CW?

A: Is algorithm2e available in Spanish?

Spanish is not supported out of the box, I'm afraid. Here's what you should redefine; I leave the translation into Portuguese as found in the package, so Spanish people can adjust it (I marked this as Community Wiki). \makeatletter %%% this is from the \DeclareOptions part \renewcommand{\listal...

LaRiFaRi

11:56 AM

@PauloCereda Thanks for tex.stackexchange.com/a/175163 Works great. Such a relief...

That was really the only thing I would dare to decry for the use with arara. Knowing, that it was TCs or Windows fault, of course.

Great tool. Have fun, finishing the next version. Will be testing it...

Paulo Cereda

@LaRiFaRi: wow, it did work? Great to know, I might include a note in the manual.

:)

LaRiFaRi

@PauloCereda wait a second, I will try a few more cases.

Paulo Cereda

I will be back soon. Time to get another bus, I just arrived in São Paulo. :)

LaRiFaRi

Why do I always think of vacations when I here such a sentence?

São Paulo, o que é uma inveja

@PauloCereda ready testing. Works like a charm. You can write your note. Thanks.

Henri Menke

???

@egreg According to your profile it's 279k.

David Carlisle

12:10 PM

@HenriMenke I think it shows teh network total here not just tex.sx main site

Torbjørn T.

@HenriMenke Chat rep is sum of rep on all SE sites.

LaRiFaRi

maybe the counter got bored

Henri Menke

@TorbjørnT. @DavidCarlisle Then why doesn't it display 11.5k for me, but 11.4k?

Torbjørn T.

@HenriMenke It does display 11.5k for you ...

hugovdberg

@HenriMenke those counters are only updated every 24 hours or so, so it might lag behind a bit every once in a while

@TorbjørnT. does show 11.4 to me too

Henri Menke

12:12 PM

hugovdberg

@TorbjørnT. oh, refresh of the whole page fixes it :P

Henri Menke

@TorbjørnT. Weird.

@TorbjørnT. You're right. Refreshing fixes it.

egreg

12:31 PM

@HenriMenke In chat the sum of reps in the various SE sites is shown; well, already said. ;-)

Gonzalo Medina

If someone could please help me uploading an image of the output in this answer: tex.stackexchange.com/a/175384/3954 I'd be thankful.

Torbjørn T.

@GonzaloMedina Done.

David Carlisle

1:21 PM

@egreg no bugs in longtable, as you know:-) tex.stackexchange.com/questions/175377/…

LaRiFaRi

@HeikoOberdiek Wanna have a look on this? tex.stackexchange.com/q/175385

Heiko Oberdiek

1:38 PM

@LaRiFaRi Done.

Joseph Wright

@HeikoOberdiek Any more issues likely for expl3 at present?

David Carlisle

@HeikoOberdiek I didn't know you were around, beat you by 10 seconds I think:-)

Heiko Oberdiek

@JosephWright No at present.

Joseph Wright

@HeikoOberdiek OK, in that case I'll build for CTAN, then I can start on the next things to add :-)

@DavidCarlisle Been looking at the XeTeX code: tricky to track down what is going on with ^^ notation!

Heiko Oberdiek

@JosephWright Do not wait for me unless you want to wait forever until I have reviewed the last byte of the code. ;-)

Joseph Wright

1:44 PM

@HeikoOberdiek :-)

@HeikoOberdiek Was mainly the generic interface business: bugs in other parts of the code can get fixed whenever they come up [the release schedule is 'when Joseph feels like it' :-)]

David Carlisle

@JosephWright q on site with xparse and xetex and input encodings

Joseph Wright

@DavidCarlisle Yes, saw that

Heiko Oberdiek

@DavidCarlisle 10 seconds faster does not mean correcter: pdfTeX does not use pdfmark operators, for example. Also the pdfmark operators are passing their stuff more or less unmodified to the PDF layer.

David Carlisle

@HeikoOberdiek yes I know I looked at the dvips backend as that writes pdfmarks (which I could look up) rather than pdftex primitives which in general you have to know how to map to pdf:-)

@JosephWright do you use the texlive sources or the xetex subversion or khaled's github copy or...

Heiko Oberdiek

@JosephWright Spotted an oddity in \expl_pdfstrcmp: The category code of space is not ignore, then the strings for l3kernel.strcmp do have additional spaces at the begin and end. This is an unnecessary runtime penalty. Fix: "\luatex_luaescapestring:D {#1}" and "\luatex_luaescapestring:D {#2}"

Joseph Wright

1:55 PM

@DavidCarlisle I've been looking at Khaled's GitHub, but that doesn't make much different to the content!

@HeikoOberdiek Ah yes: I know Lua ignores spaces but I guess not inside arguments :-)

Heiko Oberdiek

@JosephWright Spaces matter inside quoted strings.

Joseph Wright

@HeikoOberdiek Yes, I can see that!

LaRiFaRi

@HeikoOberdiek Thanks.

Heiko Oberdiek

2:12 PM

@JosephWright l3kernel.strcmp: A = A or {}; B = B or {} is wrong. A and B are supposed to be strings. If A is a string and B is nil or false, then B becomes an empty table. The comparison A < B compares a string with a table. Lua does not like this (-> error).

Joseph Wright

@HeikoOberdiek I thought good Lua practice was always to do <var> = <var> or {}

Heiko Oberdiek

@JosephWright @JosephWright At least you need the correct type, e.g.: A = A or "".

Joseph Wright

@HeikoOberdiek OK, that makes sense: will change

Heiko Oberdiek

@JosephWright I would drop the "initialization". If called by \expl_pdfstrcmp, the arguments are always strings and nothing to do. Otherwise if you want to have parameter validation, then you need to check the argument type, that the parameters are strings.

Joseph Wright

@HeikoOberdiek Like I said, my reading of the Lua book, etc. is that you are supposed to do this routinely

as arguments are not 'required' in Lua in the way they are in TeX

@HeikoOberdiek Anyhow, this doesn't prevent a release in the sense it's not likely to go wrong at present

Heiko Oberdiek

2:23 PM

@JosephWright Then keep the nil checks: A = A or "" and B = B or "".

Joseph Wright

@HeikoOberdiek I'll think about this some more: there are other issues here I'm not 100% about (e.g. should it be \expl_pdfstrcmp, \kernel_pdfstrcmp, ..., what is the 'correct' Lua namespace to be using, ...)

@HeikoOberdiek Currently I've gone for that: as I say, needs some thought

Euryris

2:59 PM

[Fancyhdr] Does anybody here know of a command that prints elements from fancyhdr at a timing of my choice ?

David Carlisle

@Euryris you're asking a lot of heading questions but not really giving any indication of what you are trying to do, controlling page headings is asynchronous, tex may have processed into the next page or pages before the output routine is invoked to split up the vertical list constructed into each page, so macros you set on page 5 can affect the head on page 1.

Euryris

@DavidCarlisle I'm trying the best I can to avoid spamming the main page... I have a lot of different approaches to the same problem and none of them seem to work in the end... What I want to do is somewhat well-documented in the "Automating links to next and previous section in fancyhdr"-thread... The issue is that the appendices environment doesn't allow me to take commands past the \end{environment} barrier

LaRiFaRi

Where do I report bad symbols from Asana Math to? See here: tex.stackexchange.com/a/175432 The white tortoise brackets look different and I don't know, if it is something to report to unicode-math or to Asana Math (for the second, I have no contact). Thanks

Euryris

@DavidCarlisle My request will require a section hack no matter what, but that hack won't "save" the last section name from my appendices to display it correctly on the last page and I would argue that the regular section commands from the kernel won't be discarded either

will be discarded as well*

Joseph Wright

3:15 PM

@LaRiFaRi Font issue, so needs to be reported to whoever looks after Asana Math

David Carlisle

@Euryris but as I asked in a comment earlier how come you have appendices as an environment (which class are you using)

LaRiFaRi

@JosephWright Thanks

Anyone in contact to Apostolos Syropoulos

Joseph Wright

@LaRiFaRi Perhaps e-mail CTAN and ask them to forward a message (they'll almost certainly hold an e-mail address, but can't give it out)

Euryris

@DavidCarlisle Referring to documentclass? In that case: article... I'm using appendices as an environment because I want to make a textbook with extensive background info, it's actually mostly background info that is non-mandatory to meet the goals for this subject

LaRiFaRi

@JosephWright Good idea. Will do this. Thanks again

Euryris

3:22 PM

@DavidCarlisle Admittedly going through all this hassle is also non-mandatory, but I'd also like to understand how these packages behave because I use them frequently and this is one hiatus I've yet failed to address

David Carlisle

@Euryris but making it an environment has no advantages and several disadvantages (and it's not the intended or documented use in article which is \appendix)

Euryris

@DavidCarlisle I didn't look at the problem that way yet. I'll try and construct something like that.

And environments do have advantages for users that do not require very specific functionality in their documents.

David Carlisle

@Euryris not if the use is a syntax error (unreported). You can't just take a random tex command and use it as an environment. It works in some cases but not here.

Joseph Wright

3:38 PM

@DavidCarlisle We should finish LaTeX3!

David Carlisle

@Euryris Your example is the page breaking analogue of the common error for linebreaking when people go {\large some text} the problem being that \large goes out of scope at the } so the paragraph is set with normal baselines. In your case you have an incorrect environment group making the page breaking settings go out of scope before the end of document, but it is same issue really.

@JosephWright OK, after the snooker.

Joseph Wright

@DavidCarlisle :-)

Euryris

@DavidCarlisle Your way of saying it was more elaborate and well-put but that was what I was getting at.

David Carlisle

4:16 PM

@JosephWright your expl3 announcement reminds me I havent announced 2e, Robin said to wait for ctan announce but I think I'll send something to latex-l anyway, it's had a day to reach mirrors

Paulo Cereda

4:39 PM

@LaRiFaRi Thank you very much for testing. :) I'll try to provide a better Windows experience in the next release. :)

David Carlisle

@PauloCereda did you bring Psmith? (I'm sure @egreg would be interested)

Paulo Cereda

@DavidCarlisle I'm so sorry, he's not here. :(

David Carlisle

@PauloCereda typical:)

egreg

@DavidCarlisle Well, it's egreg 275 versus David 290, nothing to be worried about. :P

Dennis

I have a question if anyone knows the answer. What are the advantages of using the memoir class with the article option over the standard article class? I gotta run, so please ping me if you have an answer.

egreg

4:49 PM

@Dennis memoir has many more features than article.

Dennis

@egreg But features that aren't reduplicated with various packages? I know, for instance, it has its own mechanism for headers that is supposed to be better than fancyheader for some purposes, is it just a lot of stuff like that which causes people to prefer memoir?

David Carlisle

@Dennis even if the functionality comes from including existing packages there are (or can be) advantages in having the class maintainer check which packages work together, and what order they need to be loaded, and offering an interface that "just works" of course the disadvantage of a bigger system is that in order to do that it has its own conventions and rules, which you need to follow, so another manual to read

LaRiFaRi

5:52 PM

@PauloCereda No, I thank you. You are doing the work here. Don't spend to much time on windows :-)

Paulo Cereda

6:53 PM

@egreg: how's the battle score? I'm on class. :)

David Carlisle

7:14 PM

@PauloCereda level:-)

@PauloCereda I could have just got ahead but @Werner said that it was a duplicate of my own answer so I deleted (he just doesn't want me to catch him up:-)

tohecz

9:28 PM

Mark Selby is snooker world champion 2014!

David Carlisle

@tohecz I wondered if you were watching:-)

tohecz

@DavidCarlisle Of course. And I saw Neil getting beaten in SF as well

@David which is correct, please?

I hope we'll manage to make progress in June.
I hope we'll manage to make some progress in June.

David Carlisle

Both are correct but have different emphasis, but I'm struggling to find words to say how they differ:-)

tohecz

@DavidCarlisle well, I feel it as "make progress" = "advance"

and "make some progress" = "finally do something about it"

David Carlisle

@tohecz yes I was trying to think if one of them implied that currently you are stuck, but the meanings are so similar it's hard to say, you could also say "make more progress in June" which is more explicit that progress is currently slow

tohecz

9:38 PM

@DavidCarlisle e-mail already sent with "some progress" :)

David Carlisle

@tohecz :-)

Installing [0741/2834, time/total: 48:24/02:48:19]: dvdcoll [211k]

tohecz

I'm writing to my supervisor, he's an Austrian guy and he prefers to be fair in words, no need for extra politeness (= use "more progress")

@DavidCarlisle I'm gonna do that on Wednesday on my boss' new computer

David Carlisle

@tohecz I picked a mirror in .cz hope that was the right choice.

tohecz

@DavidCarlisle it's on our university servers :)

it's feld.cvut.cz?

David Carlisle

@tohecz cstug.cz wherever that is really

tohecz

9:42 PM

ah ok there're to Czech CTAN mirrors

I'd really a bit more on cvut.cz than cstug, but it's not that much different since both are on PASNET (Prague Scientific Network)

David Carlisle

@tohecz I don't think the pretest is on the usual ctan mirrors (no UK mirror was listed)

tohecz

@DavidCarlisle pretest?

David Carlisle

@tohecz tl2014

tohecz

@DavidCarlisle ah ok

quite possible

I think I have tl2013

David Carlisle

@tohecz so do I, that's why I'm updating:-)

tohecz

9:45 PM

oui, c'est ça (sorry, that was for my tl2013 message, it took some time to find out how to write French on this computer)

Hey @Paulo ! How're you?

David Carlisle

@tohecz It's taken me years and haven't managed yet:-)

egreg

@PauloCereda Even at 305

tohecz

@DavidCarlisle all the accents are on my Czech keyboard. But they were accessible via AltGr+Ctrl on my previous computer, while it's via AltGr+Shift now.

David Carlisle

@tohecz I have no idea how to get accents on this keyboard:-) (I just use emacs input methods or more likely write in English and get google translate to add the twidles)

tohecz

@DavidCarlisle ah yeah

btw, I passed an exam today!

David Carlisle

9:49 PM

@tohecz congrats

egreg

10:07 PM

@tohecz Yahee!

tohecz

@egreg it was one of the funniest exams I have ever passed

@egreg I stated an equivalence because I was convinced it's an equivalence. The guy asked me to prove the implication that was not in the book, not telling me it wasn't in the book. After 30 minutes he told me: "You know, I gotta confess the proof not in the book, I quite hoped we'll manage to prove it here."

egreg

@tohecz :)

David Carlisle

@egreg know anything about microtype/vtex ? I thought they were still going but website last updated in 2005...

egreg

@DavidCarlisle Never tried.

David Carlisle

10:22 PM

@egreg nor me I never tried it (but I think I was given a CD at a tug meeting once:-) but they had an interesting set of fonts..

egreg

10:41 PM

@DavidCarlisle Yes, but only bitmap in the free version.

David Carlisle

11:06 PM

@egreg ah

egreg

@DavidCarlisle You had to buy the full version. The possibility of directly interpreting/embedding PostScript was very interesting. But it seems they disappeared.

Paulo Cereda

11:25 PM

@tohecz: hi Tom, sorry for the late reply. I'm on my smartphone and the signal is very weak in this particular area. Hopefully I will arrive home in 45 minutes. A very busy day in São Paulo.

@tohecz: oh and congrats for passing the exam! Yay!

tohecz

@PauloCereda Thanks!

@PauloCereda Now tell me where's the score sheet from the scout party at my home 4 weeks ago, and you'll be the man of the ~~year~~ night :D

Paulo Cereda

@tohecz: inside the refrigerator? :)

tohecz

@PauloCereda :-O I confess I didn't check that :p

Paulo Cereda

LOL
