Is 4.0mu plus 2.0mu minus 4.0mu equal to just 2.0mu?

1:02 AM

@Tom No...

It's 4mu when no stretch or shrink is applied/necessary. It can be shrunk down to 0mu (4mu minus 4mu) or stretch out to 6mu (4mu plus 2mu), depending on what is optimal according to TeX's paragraph algorithm.

@Manuel I've raised the xparse business with the team (again) (@DavidCarlisle will have seen the mail)

Joseph Wright

9:11 AM

@DavidCarlisle I see we are in agreement

David Carlisle

@JosephWright of course:-)

pot of gold?

10:04 AM

@Johannes_B :) @percusse

@Tom no, but adding 4mu plus 2mu minus 4mu and 2mu plus -2mu minus -4mu gives 6mu exactly :D

Good maen;-)

tohecz

@ChristianHupfer hi there

Christian Hupfer

@tohecz: Hi to Paris/Prague ;-)

tohecz

@ChristianHupfer Paris currently ;)

Christian Hupfer

@tohecz: Well, probably nearer to me than Prague :D

@tohecz:: Yes, Paris is 515 km distant to my place (which will be only three days left), whereas Prague is 598 km away

tohecz

@ChristianHupfer depends on where exatly you are :) because I think that it's approximately half and half in Germany

Christian Hupfer

10:47 AM

@tohecz: Given two capitals, I am basically in the middle of nowhere ;-) But it's very near to the border to France, the Rhine river is about 15 km from here

Q: What are the main differences between Texmaker and TeXstudio?

Although I've read these two posts: Texmaker vs TeXstudio (comparison) LaTeX Editors/IDEs I would like to ask again specifically about Texmaker and TeXstudio, because they are quite well ranked in the "Big list", and one of them was born as a fork of the other one. What are the main differen...

tedious to answer that. More a "do-it-for-me" question in me eyes.

Christian Hupfer

@LaRiFaRi: I think it's not off-topic, but will lead to opinion-based answers (if any)... for me, it's one of those boring questions on TeX editors

LaRiFaRi

@ChristianHupfer yea, I meant "off-topic 'cause too broad"

No specific problem to help with

ah well, I will leave it as it is. Maybe there is someone who did some comparison for a block or alike who'd like to answer...

David Carlisle

anyone expert in bidi....

I took the image size reported by pdftex in your original example and replaced by a rule of the same size. I now get the same error so I updated your example and deleted all my earlier comments. this looks to be an error in the right-to-left support babel package which is re-ordering pdf internals and making a "restore" come before a "save" and corrupting the command stack. — David Carlisle 4 mins ago

tohecz

12:25 PM

@DavidCarlisle well, is that an error in bidi or in graphicx? :D :P (and why there's no smiley :C?)

David Carlisle

@tohecz I was just going to ask @JosephWright that same question, Joseph do you know if the save/restore pairs in the L3 drivers are safe wrt bidi controls? (Also I haven't quite worked out where in the output routine it trips, it's sensitive to the float size.

egreg

2:31 PM

No @PauloCereda, no party. :(

David Carlisle

@egreg you could have a party for my new badge

egreg

@DavidCarlisle Still 28 to 12, no battle.

David Carlisle

@egreg mine are shinier

anyone know if this is a duplicate (it must be but...)

Johannes_B

2:53 PM

Do we have a question that does something like page 1 of X doing it per section/chapter/part/level?

LaRiFaRi

@egreg one question to your last item in tex.stackexchange.com/a/83936

\mathrlap{<math>} is similar to \mathmbox[0pt][l]{<math>}

When I print \[\begin{array}{l}\mathrlap{B} \\ \mathmbox[0pt][l]{B}\end{array}\] I am getting something wrong.

Q: Table border is not complete

I want to draw a table and i used the following code \begin{table}[htbp] \centering \caption{Ship simulator required inputs} \begin{tabular}{|c|c|} \hline L_{PP}, L_{WL}, L_{OS}, B, T, T_{a}, T_{f}, C_{B}, D_{P}, `\\` Bulbous bow, Number of bosses, brackets, thrusters. & ship particulars `\\` ...

tables

LaRiFaRi

@egreg The result is B
[0pt][l]B

egreg

@LaRiFaRi \mathmakebox

@LaRiFaRi \mathmbox doesn't accept optional argument, like \mbox

LaRiFaRi

@egreg thanks. perfect. Do you want to edit that or shall I?

Or did I just misunderstand your phrasing?

egreg

3:03 PM

@LaRiFaRi Done

LaRiFaRi

@egreg thank you

egreg

@LaRiFaRi Thank you for noting!

@Johannes_B Why not using zref-lastpage?

6:44 PM

@Johannes_B Yes why not?

Joseph Wright

7:25 PM

@DavidCarlisle We've not tackled bidi or wider directionality at the moment. This is an area we need some discussion on, both internally and with others.

David Carlisle

@JosephWright suspected as much but while not having an ideal interface is sort of OK, corrupting the pdf stack and getting no document, isn't so good....

percusse

8:07 PM

@DavidCarlisle In some languages they are kind of the same

Johannes_B

@egreg @percusse An OP asked for something along the line of page x of y for every appendix part. I am not comfortable with this.

Christian Hupfer

@Johannes_B: Where? On LC?

Johannes_B

@ChristianHupfer golatex.de/…

@ChristianHupfer I recall you did something like this a while ago, but i was too lazy to search for it.

Christian Hupfer

@Johannes_B: I was young and needed the money ;-)

barznjy

@egreg it is Arabic language.
it tells you that you can watch the match between Barcelona and Ajax from that link.
But I think it is not safe to open these links.

Johannes_B

8:18 PM

@ChristianHupfer Personally, i think there are too many trip wires. Put i can understand the OP.

egreg

@barznjy Yes, I saw exactly that in the translation. We're lucky that spammers are quite rare here.

Christian Hupfer

@Johannes_B: As far as I understand the question, the OP wants a per appendix 'page 5 of 17' stuff?

Johannes_B

@ChristianHupfer Yep, but per part

@ChristianHupfer But i don't know the real doc

Christian Hupfer

@Johannes_B: Appendix, part, all the same :-P

@ChristianHupfer I think ConTeXt would do wonders here.

Christian Hupfer

@Johannes_B: I know nothing about ConTeXt, but if you know more ... go ahead

Johannes_B

@ChristianHupfer Unfortunately, i don't know a thing either.

And i think the starting rain is forcing me to go home.

See you guys. And farewell.

Christian Hupfer

@Johannes_B:See you

Joseph Wright

9:12 PM

@DavidCarlisle Yes, true, but for expl3 we do want to avoid adding stuff only to remove it if we can. What we really need is someone with bidi experience.

David Carlisle

@JosephWright yes sure I just wondered if I could steal some code back to graphics now, but I guess not....

Joseph Wright

@DavidCarlisle Sorry

David Carlisle

:-)

Joseph Wright

@DavidCarlisle But this is something we need to address

@DavidCarlisle First we need to decide what is 'supposed' to happen, e.g. with \hbox:n

Tom

Hey I'm trying to call a command like so: \mycmd[option1,style={->{size=2mm},shorten <= 1pt}]{stuff} #1 gets passed to pgfkeys, but it is stripping off the internal {} around {size=2mm}. What is the proper way to keep them?

David Carlisle

@Tom probably double them

Tom

Tried that, didn't seem to wrk. Basically, I'm getting: Unknown arrow tip kind 'size=2mm,shorten <= 1pt'.

which makes sense, if the { } are stripped.

option1 goes to one pgfkey, and style goes to another. both via /.store in=

David Carlisle

@Tom it won't strip forever triple, quadruple:-) it's actually quite hard to write a parser for key value stuff that never strips braces

Tom

oh dear. Unknown arrow tip kind '{size=2mm},shorten <= 1pt'.

maybe it's time to post a question

David Carlisle

9:44 PM

@Tom I forgot to mention I know absolutely nothing about pgf:-)

Manuel

10:09 PM

After reading a recent question I started playing around… and find something I don't know if it's the expected behaviour or a bug in unicode-math.

\setmathfont[Color=red]{Asana Math} (or whatever font) only changes its color on inline math, not on display math.

egreg

@Manuel In some cases it's hard to know what the expected behavior of unicode-math.

@Manuel However I get red in both inline and display math with this

\documentclass{article}
\usepackage{unicode-math,xcolor}
\setmathfont[Color=red]{Asana Math}
\begin{document}
$a+b=c$
\[a+b=c\]
\end{document}

With XeLaTeX; with LuaLaTeX the display is black. Blame luaotfload

Manuel

Okey, true. I was using lualatex.

David Carlisle

10:29 PM

hmph no more palindromes for a while:-( (I can't have understood the question as @ChristianHupfer's accepted answer doesn't have any overlapping as I understood it:-)

Telemachus

11:04 PM

It seems surprisingly hard to have sections but not print them (using titlesec at least). Would people say it's discouraged?

(Just thinking about pros and cons and whether this is worth spending much time on.)

David Carlisle

11:17 PM

@Telemachus \iffalse \section{gone} blah blah ..... \fi \section{visible} hello ... ??

Telemachus

@DavidCarlisle Ah, I'm sorry: I was not very precise. I meant rather to declare a section name (for ToC and header of the page), but not have that name printed in the body of the page.

@DavidCarlisle If I understand your code, it would suppress the entire section, yes?

David Carlisle

@Telemachus yes, but what you say is easy enough really

Telemachus

Oh? I've only found this tex.stackexchange.com/questions/16050/…, and it still leaves the actual spaces (empty lines) where the section name would have been. (Which seems awful and bizarre to me.)

David Carlisle

section is

\newcommand\section{\@startsection {section}{1}{\z@}%
                                   {-3.5ex \@plus -1ex \@minus -.2ex}%
                                   {2.3ex \@plus.2ex}%
                                   {\normalfont\Large\bfseries}}

in article so you can replace \normalfont\Large\bfseries by \@gobble and the heading will go and change the lengths to 0pt and the space will go

Telemachus

/me smiles

David Carlisle

11:22 PM

why do you want to do this?

Telemachus

I'm so glad that my copy of The LaTeX Companion is on its way. I need to understand better what the plugins I use are built on.

David Carlisle

@Telemachus and I get money:-)

Telemachus

Why? Aesthetics I suppose. I'm using section names as headings on each page, so it seems ugly and redundant to have a page that prints "Section foo" immediately under "Section foo".

Happy for you to get the money. It seems like a great book.

David Carlisle

@Telemachus well the other way of course is not to touch sections at all and directly attack the headings so \markboth{boo} puts something in the head and \addcontentsline{toc}[section}[zzz} adds a line to the toc

Telemachus

@DavidCarlisle Yes, I had come across that suggestion. But to my mind, the sections are useful since they are part of the structure of the document. I want to include them. I just don't want to see them (on the page itself).

Anyhow, it just seems as though it would be something more people would want (at least for some books/material), but apparently it's a rare desire. That surprised me since many books don't actually display such section names on the pages.

David Carlisle

11:29 PM

@Telemachus OK, but you can define \section as \def\section#1{\markboth{...}\addcontentsline...} and omit the usual \@startsection base rather than using \@startsection with null arguments like \@gobble, but whatever works:-)

Telemachus

@DavidCarlisle Ah, now that is tempting. So I get the semantic markup in the document itself, but as you say no running @startsection for no reason.

@DavidCarlisle Thanks for both suggestions. And for humoring the odd request. :)

David Carlisle

:-)

Telemachus

11:47 PM

@DavidCarlisle One further question: the article definition of \section that you quoted seems to be redefining (or relying on) a previous definition of \section. Can I ask where that definition would be? I'd just like to see its code. Thanks.

David Carlisle

@Telemachus no, I just copied from article.cls it's \newcommand so it would complain if there was a prior definition (you need \renewcommand to change it afterwards of course)

Telemachus

@DavidCarlisle Ah, right. I mistook {section} inside the body for \section. My mistake. So then \@startsection inside the body must be doing some of the work of putting things into the toc etc.?

David Carlisle

@Telemachus yep if you look in article.cls you'll see \part is done "by hand" (as is \chapter in book) but all the lower level headings are thing wrappers around \@startsection which does all the work once parameterised with level, lengths and fonts

Telemachus

@DavidCarlisle Excellent. I'll poke around in there to get a better sense of things. Thank you.
