btw, on the hyphenation matter I was getting bad hyphenations in cases like kr-ishterimi, mp-rehtë (no vowel in the segment, I didnt know how to avoid those except in a case by case basis, so I put hyphenmin to 4, and there are no errors

there are words that could be better hyphenated as @egreg pointed out, but it's not necessarily an error

Hi chat!

I am using Sharelatex and i want to insert a pdf file in b/w my document

I referred here

insert-pdf-file-in-latex-document

but its not helping

mickep

04:48

@BAYMAX So, what, exactly, are you trying, and what is not working?

alfred

06:40

some music for the morning soundcloud.com/milosao-1/albfin

David Carlisle

@BAYMAX just save the pdf in black and white on your local machine and then include the b/w copy into latex

alfred

06:59

@DavidCarlisle If you look at my code there is lots of unwanted stuff

the 3mm though was intentional

David Carlisle

@alfred yes but it is wrong

alfred

you suspect it to be the problem ?

David Carlisle

@alfred yes of course latex hasn't got a hope of getting the page breaks right if every page with footnotes has 3mm of contents that it does not expect to be there

alfred

can i convert the 3mm to smth proportional to baseskips

David Carlisle

@alfred note you said your overflow was up to 7pt, and 3mm is 8.5pt so that is about the amount expected

alfred

07:03

ok, could try to run without that to verify

David Carlisle

@alfred it's an odd thing to do at all but yes of course you can use .1\baselineskip or whatever, and the same negative amount before the rule

alfred

the book is for a friend of mine, he said the line was to close

how much is a baselineskip

David Carlisle

@alfred yes but that isn't the way to fix it, although it's fine as long as you do as I show and move the line up without changing the total space

alfred

there are only 12 hboxes and one vbox of 0.93393pt once that is taken off

can you add that to the answer ?

David Carlisle

@alfred well by default 13.6pt since you are using 11pt text but otherwise it's whatever you set it to

@alfred in the test document there are no overfull vbox (which is what I would expect after the change I suggest) the hbox are not related

alfred

07:15

the hboxes are due to hyphenation, my hyphenmin of 4 is too restrictive, did you read what I was saying about the patterns last night ?

the rule is too close to the text now

I'm running texlive now

installed it yesterday but didnt know it had been replaced in my editor

David Carlisle

07:45

@alfred yes but as I say it's not related to the question as posted about vboxes

alfred

ok

David Carlisle

@alfred you will get identical output with texlive as you get with miktex they use the same program sources

alfred

is it java ?

from the gui it looks like it

David Carlisle

@alfred make footskip bigger

alfred

i tried \addtolength{\skip\footins}{2pt}

David Carlisle

07:47

@alfred gui?

alfred

graphic user interface

David Carlisle

@alfred yes I know what a gui is, but tex hasn't got one:-)

alfred

oh, the tex live manager

David Carlisle

@alfred not sure what that's written in, I never use it.

alfred

I started with java but I have always hated it's guis

texlive is actually faster, but I had gotten used to some things with miktex

@DavidCarlisle I tried \addtolength{\footskip}{10mm} but the rule is still too close

David Carlisle

07:53

@alfred well at 12mm then....

alfred

way too close

David Carlisle

@alfred I doubt it's faster in general although Ulrike posted a miktex bug this week about file searching being slow (that is now fixed in the miktex source) so perhaps you just had a passing bug.

alfred

in my case it was this tex.stackexchange.com/questions/396838/…

expl3-code.tex

David Carlisle

@alfred there is nothing subtle tex does here it inserts \vskip\footins \footnoterule between the end of the text and the start of the footnotes, so you can make \footins as big as you want but \footnoterule must take no space.

@alfred oh I think that was the question @UlrikeFischer raised the bug about, that's fixed at source.

alfred

that's quick

Ulrike Fischer

08:03

@DavidCarlisle @alfred yes at least it forced me to look at the question -- I had already wondered for some time why there was the pause (and actually wanted to blame the latex team that expl3 isn't yet in the format ;-)).

Joseph Wright

@UlrikeFischer Be careful what you wish for ;)

alfred

thanks

Paulo Cereda

Top of the morning!

Joseph Wright

@UlrikeFischer Has been suggested in the past but when we were not making any changes to latex.ltx. One might today argue we could include expl3 in the format, though as it gets updated quite a bit that might be an issue.

alfred

08:32

@DavidCarlisle I posted this question on the footnote rule tex.stackexchange.com/questions/397120/…

Yay, I've been announced!

BAYMAX

@mickep@DavidCarlisle I have a PDF file which i want to include b/w page say 3 and 4 ? How do i do that in sharelatex?

David Carlisle

@BAYMAX as I say just use a black and white pdf you convert th epdf with some ghostscript tool or simpler just print it to a plack and white file using your printer driver from a pdf viewer

BAYMAX

black and white pdf

David Carlisle

@PauloCereda they like to publicise the menu early, being an italian meeting food is an important consideration.

BAYMAX

08:43

?

for hard copy it is ok

but i have to submit the soft copy

Paulo Cereda

@DavidCarlisle oh no

BAYMAX

you meant i should use some online tool to do thaT?

David Carlisle

@BAYMAX yes but print-to-file and get a new pdf that's black and white

Paulo Cereda

@DavidCarlisle: is my firewall able of protecting me? :)

BAYMAX

sorry but i donot understand

David Carlisle

08:45

@PauloCereda wall of fire? oh a spitroast...

Paulo Cereda

@DavidCarlisle OH NO

BAYMAX

but how do it in softcopy>?

I can print them separatel and add them

David Carlisle

@BAYMAX most systems have a "print to file" option surely?

BAYMAX

why should i print when i have to submit the softcopy only? :)

David Carlisle

@BAYMAX well I thought you would find that easier than using some commandline tool to convert the pdf. "print" is only a name that the operating system gives to a file transformation it doesn't mean you have to print anything

for example on windows you typically see :

BAYMAX

08:50

cannot i include the pdf in sharelatex code?

David Carlisle

@BAYMAX make a black and white pdf first:-) then upload that to sharelatex

Harald Hanche-Olsen

@alfred This is unrelated to the meat of your question, but: You can replace \@pt with just pt and \@width with width and thereby avoid the \makeatletter…\makeatother dance. \@pt and friends are just space optimisation hacks for use in package and class files, there is no need for them in user documents.

Paulo Cereda

@DavidCarlisle ooh west wing

I understand about wings

:)

David Carlisle

@PauloCereda Presidential, it be.

Paulo Cereda

@DavidCarlisle oh no

BAYMAX

08:55

I see "Print a s grayscale" , "print as image"?@DavidCarlisle

David Carlisle

@BAYMAX greyscale is presumably OK

Sebastiano

@PauloCereda, @DavidCarlisle, @ChristianHupfer, @CarLaTeX, @egreg Good morning and to everybody

egreg

@HaraldHanche-Olsen \@pt stands for 1pt, so it's not always replaceable with just pt.

Sebastiano

@egreg Many wishes for reaching 603,457 of reputation. I vote always your answers , too.

Harald Hanche-Olsen

@egreg True. The usages in @alfred’s post all had numbers before them, though.

egreg

09:14

@Sebastiano Good morning!

alfred

@HaraldHanche-Olsen Thanks, I will try that.

@HaraldHanche-Olsen Did you mean
\def\footnoterule{\kern-3mm\kern-3\p
\hrule \width 2in \kern 2.6\p
\kern 3mm}

David Carlisle

@alfred no he meant what he said 3pt not 3\p and width not \width

alfred

I tried pt also and the original code said @p

ok right

David Carlisle

@alfred 3\p@ is another way of writing 3pt

Harald Hanche-Olsen

\def\footnoterule{\kern-3mm\kern-3pt
\hrule width 2in \kern 2.6pt
\kern 3mm}

David Carlisle

09:27

@HaraldHanche-Olsen yes although there is no real reason to backspace by the odd amount of 3mm+3pt so you could do

\def\footnoterule{\kern-3mm
\hrule width 2in \kern -.4pt
\kern 3mm}

alfred

ok, it works fine now

David Carlisle

@alfred ^^

Harald Hanche-Olsen

@DavidCarlisle :) Just trying to deal with one topic at a time. By the way, I wonder if the space saving by using \@pt and friends is worth it on modern computers? Not to mention all the occurrences of \z@ I see scattered around.

David Carlisle

@HaraldHanche-Olsen I have an answer on that...

76

A: What does \z@ do?

latex.ltx says \newdimen\z@ \z@=0pt % can be used both for 0pt and 0 so as it says it is short (and efficient) way of getting 0. You should always have a copy of the latex source file latex.ltx in a text editor window while reading package code:-), or perhaps, if you prefer, the typeset versi...

@HaraldHanche-Olsen we (well @JosephWright) relatively recently removed all the occurrences of predefined zero and one constants in expl3 and replaced by 0 and 1 literal characters. He's so modern:-)

CarLaTeX

@Sebastiano Ciao!

alfred

09:38

it's probably worth in mine, it notices every delay

David Carlisle

@alfred unless you have several hundred thousand pages the delay of two \p@ per page is going to be of the order of microseconds.

BAYMAX

Why \tableofcontents is not generating me a table of contents in sharelatex?it only dispalys the word "contents" in the file

David Carlisle

@BAYMAX run it again

alfred

we were talking earlier about expl3-code.tex loading time, what in other's computers is 1s in mine it seems to be 5

@BAYMAX Did you run it twice ?

David Carlisle

@alfred well when I first used that code it took several minutes to load, so things are improving.

BAYMAX

09:42

ever after doing twice it's displaying "Contents" only

@DavidCarlisle @alfred

Torbjørn T.

@DavidCarlisle ShareLaTeX probably uses latexmk or something, so shouldn't be necessary.

BAYMAX

> \begin{document}

\maketitle{}

\tableofcontents

\section*{Acknowledgement}

David Carlisle

@BAYMAX perhaps your document is like @PauloCereda's thesis

alfred

you have \chaper{} ?

BAYMAX

nope

Torbjørn T.

09:42

@BAYMAX \section* doesn't go to the ToC.

BAYMAX

oh

David Carlisle

@BAYMAX unnumbered sections do not go to the contents by default

alfred

the * makes htat it doesnt go to the toc

BAYMAX

can i make them manually

?

alfred

no need

David Carlisle

09:43

@TorbjørnT. I don't understand this thing called the internet, do you think it will catch on?

alfred

try this \addcontentsline{toc}{chapter}{\setlength\parindent{24pt}Acknowledgement} right after that line

Torbjørn T.

@DavidCarlisle Probably not.

alfred

replace with section though

David Carlisle

@TorbjørnT. I'll stick to a local tex installation then.

alfred

also change 24 if you need

BAYMAX

09:45

every word "section" is to be replaced by "\addcontentsline{toc}{chapter}{\setlength\parindent{24pt}Acknowledgement}" right

Harald Hanche-Olsen

@DavidCarlisle So, about 100 ns per assignment, in 2012. I think am not going to bother, in my own code. Unless I expect it to execute a bazillion times in typical usage.

BAYMAX

@alfred

alfred

no i meant \addcontentsline{toc}{section}{\setlength\parindent{24pt}Acknowledgement}

but I'm not an expert

Ulrike Fischer

@BAYMAX in 99% of all cases you don't want \section* but should change secnumdepth: tex.stackexchange.com/questions/394569/…

BAYMAX

ok

thanks!

David Carlisle

09:48

@UlrikeFischer I was going to say that:-)

Ulrike Fischer

10:00

@DavidCarlisle Sometimes I'm faster ;-)

alfred

is there some reason why your \righthyphenmin=2 in the preamble could be overrided, every hyphenation is with at least 4 letters

David Carlisle

@alfred it's reset every time you change language (or at least the effective value is the value set when you saved the hyphenation patterns)

alfred

I'll try right before \begin then

David Carlisle

@alfred actually I'm can't remember, perhaps babel language switches set it explicitly in which case you want it in your babel language definition for mixed language use, check the babel doc

alfred

I changed it in polyglossia and I think it overrides, but now I'm on livetex and cant find the right file

Q: Duck translation

Dictionary translates 'duck' as 'anatra' and 'anitra'. I googled for difference explanation and found in this topic that Italians use 'papera'. So... How should I call duck in Italian?

@DavidCarlisle you are mean

@egreg ooh

alfred

reminds me cinquecosebelle.it/wp-content/uploads/2014/11/paperone.jpg

11:21

@PauloCereda why is "like @PauloCereda's thesis" a mean thing to say? perhaps it was a compliment, unless you know something about the thesis that you are not saying????

Paulo Cereda

@DavidCarlisle oh no

David Carlisle

@PauloCereda see the excellent translation of the answer in comments?

Paulo Cereda

@DavidCarlisle Fantastic. :D

hello

yo'

@PauloCereda coming or going?!

Ulrike Fischer

@PauloCereda And how do you translate "I am a naive and friendly duck"?

Paulo Cereda

@yo' progressively. :)

@UlrikeFischer Sono un papero very amico e naive. :)

Ulrike Fischer

@PauloCereda too domestic, a bit of wild would be better. What about papatra?

Paulo Cereda

12:12

@UlrikeFischer ooh

Kirill

If I tex matrcies, I have to do it in the syntax {x&y&...\\q&w&... ...}. Is it possible to predefine the matrix size, like in Matlab, and then fill it with elements? The point is that I do not want to create 100 of macros for all possible matrices.

e.g. matrix(3,4), line1 = {}, line2 = {}, ..., or matrixelement(3,2) = 5 etc.

David Carlisle

@Kirill why do you need a macro at all? isn't it just as easy to enter x&y\\w&z as have some macro for a 2x2 matrix and enter \foo{x}{y}{w}{z} ?

egreg

@Kirill Does tex.stackexchange.com/questions/130191/… help?

David Carlisle

@Kirill in matlab you have an allocated data structure to which it makes sense to assign elements but a math mode matric is like an html table it's just a transient thing that is typeset as encountered.

Kirill

@DavidCarlisle I am texing lecture live. If they write a system of 5 linear equations, or a Sigma matrix for a singular value decomposition, I need to tex it fast, without going through the & and //. Or, counting how much spaces should I do to depict an upper triangular matrix.

David Carlisle

12:21

@egreg half a million lines of code to avoid writing 6 & :-)

@Kirill but matrixelement(3,2) = 5 matrixelement(3,3) = 6 matrixelement(3,4) = 22 is going to be slower isn't it?

Kirill

@egreg I will read that, after the lecture. Thank you. The question is generally about is that possible? I have to be able to depict matrices with a size not bigger as 20, missung some elements like in triangular matrices. And I have to do it fast.

@DavidCarlisle that might be. But imagine a matrix A, which first line and first column are defined. All other elements are 0, but, the (3,4) element is = 1. How can I put it in fastly?

David Carlisle

@Kirill anything is possible for example \m[square]{1,2,3,4} \m[upper-triangle]{1,2,3,4,5,6}` to make

CarLaTeX

@egreg One of them will be at the GuIT Meeting tomorrow :)

Harald Hanche-Olsen

@Kirill It might not be too hard to write a macro that, given \obeylines is active, expands \foo 1 2 45 9 <newline> into `1&2&45&9\`.

Kirill

is that a package, or do I miss some commands?, @DavidCarlisle

David Carlisle

12:25

@egreg could have that implemented by the end of your lecture

@Kirill ^^^

Kirill

I should mention that I am 0 in programming in tex. Only on the layout - layer. But I haven't programmed any functions or calculations in TeX.

David Carlisle

@Kirill no but it's more or less why TeX is a macro based system, the idea is you can easily make up macros for whatever input you want

egreg

@Kirill Perhaps a question on the main site is better: you can explain your needs and, maybe, a proposed syntax.

Kirill

@egreg I will do that! The idea now was to understand if TeX can do that.

David Carlisle

@egreg translated in to english "I just implemented this in my head but I'm not going to write it down unless there is a green tick and 15 points on offer" :-)

Kirill

12:29

Thanks for help! I will read this conversation again after the lecture.

egreg

@DavidCarlisle Exactly.

David Carlisle

@egreg Sono buono per l'italiano

CarLaTeX

@DavidCarlisle Google Translator failed this time :)

David Carlisle

@CarLaTeX impossible

@CarLaTeX I checked: over half the words end in o so it must be Italian

CarLaTeX

@DavidCarlisle The correct sentence is: "Sono bravo in italiano": its words end in "o" as well :)

@DavidCarlisle Btw, "sono buono" is the opposite of "I'm mean" :)

David Carlisle

12:46

@CarLaTeX perhaps that is why the system chose that form of words, it is all-knowing

Paulo Cereda

@CarLaTeX ooh

@DavidCarlisle you are mean

David Carlisle

@PauloCereda sono buono

barbara beeton

@yo' -- are the polls open at different times in different places, or are they open for more than one day? (here, the polls are open from 08:00-20:00 or maybe an hour later, and the pollworkers have to arrive an hour earlier to set up, and can't leave until the results for that precinct are closed, which is usually about an hour later. it's a terribly long day for the pollworkers!) anyhow, hope for the best.

yo'

18:58

@barbarabeeton here it's strange as the voting boxes are left unattended overnight, which IMHO poses a problem. The voting time is Friday 14--22 and Saturday 08--14

barbara beeton

@yo' -- oh, my, that is concerning. i hope that at least the rooms are locked, although that isn't a real barrier if someone is bent on mischief.

yo'

@barbarabeeton yeah, this is unfortunate. The only good thing is, the rooms are plenty of so any serious mischief would have to involve a large organization, which so far would be fairly visible.

Schopenhauer

Hi everyone..You may know this: Is it correct to call "introduction" to the first chapter?

barbara beeton

@yo' -- hope all goes well. we're off, leaving early in the morning, for a week at a place that "failed" the inspection of a prominent tour guide publisher because the rooms don't have outside locks on the doors. (it's on an island; can't get there except by boat; most of the time there are fewer than 70 people on the island; and there are snakes and alligators in unpredictable places. i love it!)

@Schopenhauer -- many authors do treat the first chapter as an introduction. but many others use the preface as an introduction. it depends on the content and what you consider it to be.

yo'

19:15

@barbarabeeton sounds great!

anyway, an uncle and an aunt came for a visit, so I'm off. Nice weekend everyone!

barbara beeton

@yo' -- i do think you'd like it. we call it "summer camp for big people". rather more comfortable than camp cots, and (although it's not encouraged) they have good internet connectivity. i suspect most of the migratory birds will already have been through, and nesting season is long over (we usually go in the spring), but the critters on the ground and in the swamps and marshes don't go far.

Schopenhauer

@barbarabeeton good..just that "introd.." sounds like "I go before first chapter", but as you say, it is plenty of works with C1 as intro..
