TeX, LaTeX and Friends

12:17 AM

@SeanAllred I once proposed a Lisp solution using recursion to a friend, and he gave me that stare people do at crazy people saying they are Jesus. :)

Sean Allred

12:36 AM

@PauloCereda But recursion is the only thing that makes sense in Lisp :)

Anything else is an awful hack. It doesn't make sense and it will run slowly.

My rule for Lisp: if it can't be solved using recursion, you're solving the wrong problem.

Stephan Lehmke

4:43 AM

@SeanAllred Luckily everything can be solved by recursion ;-)

Paulo Cereda

5:14 AM

@StephanLehmke Indeed!

what's a @-free version of \@alph ?

Paulo Cereda

5:55 AM

It's almost 3AM, I guess I should be sleeping by now.

egreg

6:42 AM

@leo Sorry, I was off line; yes, $\sqrt[k]{r}$ is irrational unless both the numerator and the denominator (when the fraction is in reduced form) are $k$-th powers.

Johannes_B

7:33 AM

@leo Package babel got restructured. Look for something like babel-spanish in the package manager

egreg

@MarianoSuárez-Alvarez \alph? It wants a counter's name as argument.

Mariano Suárez-Alvarez

8:02 AM

@egreg but I don't have a counter: just a number

is 2014's updmap supposed to be picking TEXMFLOCAL/web2c/updmap.cfg ?

@JosephWright Thanks. Good thing i saved the contents. It makes me laugh.

egreg

9:10 AM

@MarianoSuárez-Alvarez Then you need \@alph; if you want to use it in a document, add \makeatletter\let\dalph\@alph\makeatother to your preamble and do \dalph{3} in your document.

@JosephWright The change of l3 allowing spaces in file names works for the application to |kpsewhich... Thanks!

Joseph Wright

@egreg Of course :-)

egreg

@JosephWright It doesn't work with xelatex, though; but I believe it's a problem with the pipe in XeTeX.

Joseph Wright

@egreg Hmm, odd: a low-level test works. Will investigate

egreg

9:28 AM

@JosephWright Try the code by Heiko in tex.stackexchange.com/a/179748/4427 With xelatex I get no PDF output unless I add -no-pdf and do the conversion manually.

@MarianoSuárez-Alvarez Yes, it is supposed to. But it's already in TL2013

Joseph Wright

10:03 AM

@egreg Odd: if you \show the macro the content is fine

@egreg Something to do with the loop/eof test: try without that

egreg

@JosephWright And, quite strangely, the more complex L3 code I have gives different results when xelatex is used instead of pdflatex or lualatex: with xelatex the sequence I'm trying to populate results empty, while with pdflatex and lualatex it's populated as expected.

Joseph Wright

@egreg Indeed: if you \tracingoutput=1 here the shipouts are the same for XeLaTeX and pdfLaTeX

@percusse Sorted :-)

percusse

@JosephWright Thank you! I am trying out Linux so that is indeed a very good reference.

Joseph Wright

@percusse I didn't actually do anything, just noting that the upvotes will result in badges :-)

percusse

@JosephWright on behalf of the upvoters then hehe

Paulo Cereda

@percusse I upvoted it. :)

percusse

10:42 AM

@PauloCereda Why am I not surprised? :)

Paulo Cereda

@percusse You shouldn't, you are the captain of the Voting Squad. :)

percusse

@PauloCereda Says the highest voter of the whole SE network

Joseph Wright

@percusse :-) Was just checking that

Paulo Cereda

39999 votes

I am one vote away, let me fix it!

percusse

@JosephWright There must be some exception implemented for him. 40 votes are too few he should at least get 400. That would keep him busy for another 10 minutes.

Paulo Cereda

10:46 AM

@percusse LOL

Joseph Wright

@percusse If you look in general, we do very well for voting (I'm I guess top 20-ish network-wide, for example, and SO had a bit time advantage)

percusse

@PauloCereda Holy..... that means you caused 400K rep points. Almost the top row of the highest rep :)

@JosephWright How do you look at it network wide ? Data query?

Paulo Cereda

Hey, the counter is stuck in 39999!

percusse

@PauloCereda Please don't tell me you broke SE

Paulo Cereda

@percusse I guess I did!

Can't believe those developers used small integers for vote counting.

Guys it's true! The counter is frozen! LOL

percusse

10:53 AM

hahaha

go to MSO then

Paulo Cereda

@percusse: oh it's updated now.

Bah, it would be funnier if I really had crashed it. :)

egreg

@PauloCereda Could you sleep after the big delusion? ;-)

Paulo Cereda

@egreg The game? :) I blame Fred.

egreg

@PauloCereda And Ochoa, of course.

Paulo Cereda

@egreg Indeed!

Stephan Lehmke

10:58 AM

@PauloCereda What's up with the player's names anyway?

Paulo Cereda

@StephanLehmke What happened? :)

A: Poisson disc sampling implemented in luatex

As promised, here is my implementation. It is composed of two files: poisson.lua contains the implementation in lua of the algorithm described here. The "main" function is generate_poisson() which returns a Lua array of points, being each point a pair (x,y). In addition, the function poisson_po...

@PauloCereda Fred, Jo, Oscar, Willian - are these real names or do they want to stay anonymous :-)

Paulo Cereda

@StephanLehmke Surprisingly, those are really their names (except Jô, his name is João). It's very common to refer to players in here by their first names, not their last names. :)

egreg

@PauloCereda Or by a nickname, like Pelé or Zico

Paulo Cereda

@egreg Ah yes, indeed. :)

egreg

11:12 AM

@PauloCereda But Falcão was known by his last name

Paulo Cereda

@egreg A couple of them. :) You know the real name of Júnior? :)

egreg

@PauloCereda Leovigildo, IIRC

Paulo Cereda

@egreg Wow! That's correct!

egreg

@PauloCereda Oh, I see it should be Leovegildo.

@PauloCereda Great player, even if he played for Torino.

Paulo Cereda

@egreg Cool. :)

@egreg: of course my favourite player is Ademir da Guia. :)

@egreg youtube.com/watch?v=byFKSqyaNtY

egreg

11:31 AM

@PauloCereda It's unfair: there are two Zicos on the pitch. ;-)

Paulo Cereda

@egreg LOL

egreg

@PauloCereda A bit overweight, at least.

@PauloCereda Let's say that Estrelas' defense wasn't really tough.

Paulo Cereda

@egreg :)

1:04 PM

@percusse, @JosephWright, @PauloCereda: thanks!

My second gold badge for that answer :D

egreg

@Silex Hey! I did upvote, too! And when it was below 100. ;-) After all, you're citing my paper on TUGboat. :)

Silex

@egreg and all other upvoters: thanks a lot ;)

egreg

@JosephWright Here's a test for the nonworking pipe in xelatex:

\documentclass{article}
\usepackage{xparse}

\ExplSyntaxOn
\ior_new:N \g_pipe_test_stream

\ior_open:Nn \g_pipe_test_stream { |kpsewhich ~ -all ~ texmf.cnf }
\ior_str_map_inline:Nn \g_pipe_test_stream
 { \tl_show:n { #1 } }

\stop

With pdflatex and lualatex I get

<recently read> }

l.9  { \tl_show:n { #1 } }

?
> /usr/local/texlive/2014/texmf-dist/web2c/texmf.cnf.

With xelatex nothing at all

@JosephWright I tried on a GNU/Linux box and it works. Tried on another Mac OS X box, failed.

Joseph Wright

@egreg OK, so a Mac-specific issue?

egreg

@JosephWright It seems so.

Joseph Wright

@egreg 'Not my fault' then ;-)

David Carlisle

3:09 PM

@egreg gets an honourable mention in my latest answer

egreg

@DavidCarlisle Just seen. ;-)

Mariano Suárez-Alvarez

@egreg Yup, that's what I am doing :-) I find it slightlyweird that there is no user command for that.

David Carlisle

@MarianoSuárez-Alvarez question is, how come you have a number that you want to print as a letter? the model was I think that either it's dynamically calculated so in a counter, or if it's a literal 2 you don't really need \@alph you can just use b (I know the model of latex doesn't always match user behaviour but still:-)

Mariano Suárez-Alvarez

I have a \thmitem command which gets a number and formats it in the form (a), which I use in my text to refer to parts of theorems (which I have numbered in that way) I know I should be defining all these commands in a style file, so I am not complaining much! (setting labels and using \ref's would probably beat all other options, but that usually takes more typing for things that get often used exactly one time)

David Carlisle

@MarianoSuárez-Alvarez well that unquestionably should be a counter accessed with \ref that prints \theyourcounter using \@alph, so not a use case for making \@alph a user callable command:-)

Paulo Cereda

3:33 PM

Ack?

egreg

@PauloCereda David has removed a % at the end of a line. A coup de maître. :)

Joseph Wright

@egreg I'd still have a % :-) (with a space, of course)

leo

@Johannes_B yes, I had to install that, thanks

David Carlisle

3:51 PM

@JosephWright harder to squeeze in a reference to @egreg if you use that form. Personally I'd use \@ne

leo

@egreg no problem :-) I thought it would help here, but it seems it won't

Joseph Wright

@DavidCarlisle Fair enough

Paulo Cereda

@egreg :)

egreg

@leo About your question: any nonzero positive rational number $q$ can be expressed in a unique way as $q=\prod_{p\in P}p^{a(p)}$ where $a(p)$ is an integer (positive, negative or zero) and $a(p)=0$ for all but a finite number of primes $p\in P$ ($P$ is the set of natural primes). Now prove that $q$ is the $k$-th power of a rational number if and only if $k$ divides $a(p)$ for all $p\in P$.

leo

@egreg thank you

egreg

4:04 PM

@leo It's basically the same as for integers.

leo

@egreg yes

rationals have a prime decomposition just like integers by allowing integer exponents

and btw it allow us to prove that $(\mathbb{Q}^\ast,\cdot)$ and $(\mathbb{Z}, +)$ are isomorphic groups

egreg

@leo Not really: the multiplicative group of positive rationals is a free abelian group of countable rank.

leo

@egreg let me see

yes, I no longer can edit

@egreg I mean positive rationals and polynomials with integer coefficients. Indeed otherwise is not true

egreg

@leo OK

s__C

Hi

I'm always struggling with tikz and matrix. But this time it should be an easy one. Let's assume I have some nodes defined and that I want to connect them with arrows. I'd need \draw[->] (m-x-y) -- (m-v-w); A large number of times. Would it be possible to use only one `\draw[->] and then multiple nodes?

leo

4:22 PM

@s__C hi

@s__C what about \draw (m-x-y) [->] -- (m-v-w) [->] -- (m-v-w);?

David Carlisle

@egreg in honour of your reference wipet stole the tick in that % question:-)

egreg

@DavidCarlisle What an injustice. You should have added the reference to the TeXbook.

Torbjørn T.

4:40 PM

@leo Doesn't work, when using \draw like that you get a single path, with a single arrow.

@s__C You can use a for loop, or perhaps edge, e.g.

\draw [->]
   (m-1-1) edge (m-2-3)
   (m-1-1) edge (m-1-2);

s__C

let me try

edge is fine if it is a continuous chain

well it's a first step

Torbjørn T.

@s__C No it doesn't. If I understand you correctly.

s__C

yeah you're right. but you have to repeat the coordinate if you don't want the arrow to cross the node.

leo

@TorbjørnT. I see

@egreg And one player of Palmeiras. :)

Alan Munn

@egreg I have no sympathy. :)

Commentator: "Spain looking like a sad parody of their former selves."

Stephan Lehmke

@egreg This is a group of death if there ever was one.

egreg

@StephanLehmke Spain wasn't expected to be so weak.

@AlanMunn We'd say “vecchie glorie”. :)

Alan Munn

@egreg It certainly seems that way.

Paulo Cereda

7:54 PM

@egreg My thoughts exactly. And also king Juan's fault. :P

"Oh in Spain we have the best league in the world." But this league is not made with Spanish players.

egreg

@PauloCereda That's the same for all European leagues.

Paulo Cereda

@egreg How's the limit for foreign players in a team?

I think Brazil limits to 5 foreign players.

egreg

@PauloCereda There's no limit for EU players; I guess in Italy not more than 3 non EU players, but many have become EU citizens.

Paulo Cereda

@egreg Oh my.

egreg

@PauloCereda For instance, Inter has exactly three Italian players: one is the second goalkeeper and one played in 11 games in the last championship.

Paulo Cereda

8:04 PM

@egreg Ouch!

David Carlisle

@egreg oh I wasn't watching, money for me?

Paulo Cereda

@egreg: Palmeiras has 4: Valdívia (Chile), Eguren (Uruguay), Victorino (Uruguay) and Mendieta (Paraguay).

@DavidCarlisle Dude, you are so gonna get that money jar. :)

David Carlisle

@PauloCereda now let me see, what was that tip I got from a local expert on South American football, ah yes..

Jun 7 at 10:39, by Paulo Cereda

@DavidCarlisle I can understand about Uruguay, but Chile?!

Paulo Cereda

@DavidCarlisle Oh no! :)

egreg

@PauloCereda Slovenia: 1; Brazil: 4; Argentina: 9; Serbia: 1; Colombia: 1; Congo (Dem. Rep.): 1; Croatia: 1; Algeria: 1; Portugal: 1; Japan: 1; Kenya: 1. The Italians are actually 4, the one I forgot played in 4 games.

@barznjy What answer are you referring to?

David Carlisle

@Jens perhaps not in Germany but the Italian and Brazilian members of this chatroom think of nothing else.

Nasser

multicol package support was added as patch in 2013.  Strange thing this MWE compiles ok with tex4ht in 2014. so I think multicols is ok?

@Nasser but given you got an error about \maybe@reverse@columns I assume watever patch was made in 2013 is wrong in 2014 now multicol is updated to support placing the columns in right to left order

@DavidCarlisle I do not know what is going on. But in 2013, I used a patch from tex4ht team. And that works. Now it does not work in this large file. but it works in small MWE. I think there is interaction with another package in 2014 which was not there before. I'll check version of multicols now. The file is so big, that is the problem. about 400 pages.

@Nasser make a MWE that has a page or at least a column break in it the command you show is in the output routine (page composition)

@DavidCarlisle sure. will do that. thanks

@DavidCarlisle is this the file I need to compare between 2013 and 2014?
>pwd
/usr/local/texlive/2013/texmf-dist/tex/latex/tools
>ls -l multicol.sty
-rw-r--r-- 1 root root 26766 Aug 3 2011 multicol.sty

David Carlisle

@Nasser yes

@Nasser well first off drop in the old one and see if the problem goes away that will confirm it is the multicol change, then you just need to fix your patch (or push it back to the tex4ht maintainers)

Nasser

@DavidCarlisle what old one? I am running on new system, 2014. Did not make any changes to texlive 2014 at all. I am not using the patch at all in 2014. But only in 2013 I am. Which is on separate PC all together.

David Carlisle

@Nasser No I meant get a copy of the old (2013) multicol and drop it in the folder with tyour document and try it with texlive2014 if you get no error it confirms that it is the 2014 update of multicol that is the problem but given your comment about not using a patch in 2014 I perjhaps misunderstood you

Nasser

@DavidCarlisle sure. Will try that. Will copy the 2013 mutlicol to my 2014 PC and try that there now. I just did a diff, and there are do many changes in multicol 2013 and 2014. Ok, will now try what you just suggested.

I just need to copy multicol 2013 to same folder as the tex file, right? I do not need to copy it to /usr/local/texlive/2014/texmf-dist/tex/latex/tools ? if it is in local folder as the tex file, it will be used instead?

David Carlisle

@Nasser yes the document folder should be fine

Nasser

@DavidCarlisle great news! now the error went away on the 2014 pc ! I copied the multicol from my 2013 pc to the 2014 pc, and build clean, and no longer see the error. What to do now? Should I put the 2013 multicol.sty in place of the 2014 official one?

Is this a bug then? Should I report it somewhere?

may be I need to make a MWE and post this to make it visible?

David Carlisle

@Nasser No! don't replace it. either you found a bug in the new multicol in which case you could to make a MWE that only contains files from the core latex release and post to latex bugs, or some code you have is patching multicol assuming the old definitions and those assumptions are now wrong, in which case that code needs updating, or you can just leave multicol in your document folder and let someone else trip up later

Nasser

@DavidCarlisle that is too complicated :) I'll try to reproduce in with MWE, and post it on main board, and let someone decide what to do with it and channel it to the right place.

Dear folks, I'm out for sleeping

@DavidCarlisle guess what I found! It is the pdflatex which is failing !! not tex4ht on 2014. I thought it was tex4ht. I do pdflatex index.tex and get the error. working on MWE. This is worst than I thought.

I have a MWE !

pdflatex fails when using mutlicol package !!

@egreg: could you suggest me a good combo of fonts/math fonts? :)
