12:01 AM
@percusse Have heard of arrayjobx but have not used it -- there are also some listadd macros in etoolbox. But I tend to use \foreach as I don't know if I could do a Hello World document without tikz anymore. :-)
 
:6963618Hahah, then you should read the arrays with pgfplotstable and concatenate tables :P
 
@PeterGrill LaTeX3 version added; as you can see it's quite terse.
 
@egreg Wish I could read it. :-) So, are the spaces in g_grill_list_ #1 _clist just for readability? I find it strange. Of course I found it strange having spaces in key words with \tikz, but eventually got used to it and now I like it...
 
@PeterGrill Yes, spaces can be added at will; I like to isolate the variable part in a name.
 
@YiannisLazarides I've thought about a tex syntax that is explicitly directly mapped to mathml/html rather than the usual one, so in the case of tables commands like \td{...} \td[colspan=3, rowspan=2, class=wibble]{....} that way you can include arbitrary html features, canvas forms whatever without necessarily having to invent new tex syntax for each. Obviously in some cases you'd want to use the macro layer to hide some of this and get back to a more traditional tex syntax
 
@Kurt Hahaha!
 
@PeterGrill It's not difficult: \clist_gclear_new:N globally clears a clist, defining it if istill undefined. The :c version just uses a name in braces instead of a control sequence. Similarly \clist_gput_right:Nn globally adds to a clist variable (and the :cn variant uses a name). Then \clist_map_inline:Nn cycles over the elements. Actually sequences would be better, for this kind of application.
 
@Kurt LOL
 
@DavidCarlisle Aha! This sounds much better than my ideas. The optional part of the \td[] is the answer and a good marriage between the two. For simpler tables an extended markdown is ok.
 
Better than the tuba guy. :)
 
12:17 AM
:-)
 
For reference, the tuba guy:

@egreg Ok, now I know where to start with expl3: The naming syntax!!
@PauloCereda nice. :-)
 
@PauloCereda LOL
 
Wow, managing TL or MikTeX is a huge challenge.

Q: How can I use -max-print-line in pdftex (TexLive)?

Baptiste WichtI know that Miktex has an option -max-print-line=n to change the width of the output. I wondered if something like that existed for pdftex from TexLive ? It is very annoying to have a tool using only half the width of the screen... Thanks

Imagine how many of these tiny details needs attention.
@PauloCereda Then I have to do it again :)

@percusse LOL
I love you guys.
This is teh best place ever.
 
12:22 AM
@PeterGrill I've added the version with sequences
 
@DavidCarlisle There are also variants. As I am filtering both ways one could also simplify \td[1,2][class]. Maybe you want to make your comment an answer?
 
@YiannisLazarides OK maybe tomorrow then getting a bit late to draft a coherent answer
 
@egreg Thanks, will have a look when I get back in an hour...
 
@PeterGrill I'll be in bed. :)

i am stumped by one of the simplest things
why doesn't this produce a 5 inch wide by 2 inch tall box ?
 \documentclass [a4paper] {article}
 \begin{document}
   \fbox{
     \begin{minipage} [c] [2in] [c] {5in}
       \begin{center}
         This is some text in the middle of a 5 inch wide by 2 inch
         tall minipage.  Is it exactly that tall and wide?
       \end{center}
     \end{minipage}}

Q: How to Add 7 Authors' Name?

william007Hi I have a two columns table with ACM SIG Proceedings template http://www.acm.org/sigs/publications/proceedings-templates Here is my code for six authors, my problem is I have a 7-th author, I am not sure how to add it nicely, is it possible to squeeze the second rows(maybe smaller font size) t...

I don't know why, this question reminds me of
 
9:55 AM
hello ‮world
yippe it works
 
Is there any culture where a name such as toiletfreak has a good connotation, or at least one that anyone would want to admit to?
 
@PeterGrill Where knowledge of English is not widespread.
 
@egreg :)
 
aloha friends, is there a guide i can use for reference ?
 
@PauloCereda Our computer center had to set up email addresses for the students; the domain name proposed was stud.univr.it; I warmly suggested not using that abbreviation of "studenti".
@Shokodemon "The not so short guide" is a good starter: texdoc.net/texmf-dist/doc/latex/lshort-english/lshort.pdf
 
10:11 AM
egreg thank you very much my friend
 
@PauloCereda Do you know about neocomplcache?

Q: neocomplcache with LaTeX in Vim

toiletfreakI have a question on using neocomplcache for LaTeX code completion in Vim. It seems to be working for HTML / PHP etc, however, the pop-up omnicomplete box does not show up when editing LaTeX files. How should I proceed? By the way, I am attempting to mimic the code complete behavior in IDEs, s...

 
neocomplcache is like cheating at life
 
@Shokodemon From a vim user one can expect everything. ;-)
 
@egreg I'll take a look. :)
@egreg Not a wise choice. :P
Thanks to pathogen, it's easy for me to test that script. :)
 
10:28 AM
a guide to what exactly? (@Shokodemon)
 
10:40 AM
Guys, what's the minimum rep for accepting edits?
 
10:54 AM
@PauloCereda is that the same as the general edit priv (2000) tex.stackexchange.com/privileges/edit
 
@DavidCarlisle Ah thanks!

A: Editing Minimal Working Examples (MWEs)

Paulo CeredaIt's not really an answer, but my thoughts are too long for a comment. :) First of all, I'd like to thank you for all the effort you've put into moderncv and the time spent in helping people here. :) I really share your worries on some MWE lacking the minimal component. Indeed we have quite a b...

My two cents. :)
 
11:22 AM
@egreg: I was thinking: they could go with alumni.univr.it :)
 
David Carlisle: i wanted a guide to formatting the JS latex used here - i found it :) so it's all good!
 
@Shokodemon OK :-)
 
does this chat interface offer quick name completion ?
oh yes it does one must use @
hah.
 
@Shokodemon JS ?
 
@Da
@David
@DavidCarlisle Java Script - stackexchange uses a latex java script engine
mathJax if im not mistaken
 
11:46 AM
@Shokodemon It is MathJax but we don't use it here that's why I queried it. The tex.sx site doesn't choose to enable the mathjax formatting. (There are some discussion on meta for the reasons)
If you want mathax help the best place is its group/mailinglist at groups.google.com/forum/?fromgroups#!forum/mathjax-users
 
@DavidCarlisle oh yeah that i know that the chat site does not use mathJax, certainly. i was writing a proof on the mainsite and wondered how to go about it! i will checkout the mailing list though too !
 
@Shokodemon we don't use mathjax on the main (tex.stackexchange) site either. It is used on math.stackaexchange and some other sites on the sx network
 
oh
oh dear - i have to check my facts. it's easy to assume things.
oh wait a minute - yes i meant that. by main site i meant math.stackexchange since i came here by clicking the chat button over there. i didn't know it's not implemented everywhere though!
 
@Shokodemon that's Ok no harm done:-) It would be confusing to use it here as people here don't just want to display some mathematics they often need to ask about the darker corners of TeX's typesetting behaviour. MathJax doesn't use TeX at all so it typically does something different in dark corners
 
i see! is mathJax then an attempt at a latex-like library for the web ?
 
11:56 AM
@Shokodemon yes it takes a subset of the math part of latex syntax (it doesn't implement document level commands like \chapter or \section at all) and loads a javascript library to convert that to MathML and then to render the MathML native in the browser or by converting it to html+css or svg, so it implements an extended subset of a latex-like language but it isn't actually latex (or tex)
 
these guys are really giving it a go! impressive
 
@Shokodemon one guy not guys (for almost all the coding and design work) . Yes it is very impressive for what it does.
 
12:12 PM
wow o_0
 
1:03 PM
@PauloCereda Oh my, I am dying here .... :) Got to get out of the lab. We are now watching it on a friends phone.
 
@percusse <3
 
1:30 PM
unbelievable shocking comment here:
Thanks @DavidCarlisle, alas, I am using the verbatim package, which is not covered by that answer and am not using emacs, so the script doesn't seem to be of direct benefit. — Richard 28 mins ago
 
@DavidCarlisle The emacs part, I suppose. :)
 
Probably a vim user. There is no hope.
3
 
@DavidCarlisle <3
 
kan
OK. Time to setup emacs and stick to it.
 
You gotta love some paper titles: "Programming languages as operating systems (or revenge of the son of the lisp machine)"
@DavidCarlisle: ^^
 
kan
1:33 PM
(I have read the preliminary parts of the manual. I want to basically setup AuCTeX and Emacs; viewer: Okular).
Some references please?
And, what font do you guys suggest?
 
@PauloCereda This is kind of famous in control theory circles.
 
another day another new web browser
 
@percusse Oh my! :)
 
kan
@DavidCarlisle What?! People on earth use Chrome.
 
And another one
 
kan
1:38 PM
Not sure about bots though. :P
 
kan
Weaker than the weakest British Humour.
 
@kan chrome beta is OK chrome stable still hasn't got math support so doesn't count. I use firefox nightly as my default browser asctually. But today's new browser is IE 9 update version 9.0.11 yipee!! aren't I lucky.
 
@kan FF here too.
 
kan
Oh :(
I no like FF.
 
1:42 PM
@PauloCereda I laughed so hard now I'm listening to Lateralus to counterbalance.
 
@percusse :P
 
kan
Once again, let me ask:
Do you guys have a suggestion for font on Emacs buffer?
 
2:01 PM
@kan as Im on windows most of the time these days I tend not to stress it too much with fonts and things and just take the defaults
 
kan
@DavidCarlisle Oh, OK. :)
 
2:13 PM
@kan Take a good look at emacs' customization interface. Does it look like a tool which is meant to make it easy for you to adapt emacs to your tastes? No! It's just a thin shell beneath which lieth despair! HC SVNT DRACONES
 
kan
@StephanLehmke Exactly. So many things there...
Despair. sob
 
Meanwhile, at Vimland:
set guifont=Monofur:h12
 
@StephanLehmke I was expecting something like this from David to be honest :)
 
@kan Just adapt your tastes. emacs knows best.
 
(lisp (with (wrong (is what))))
 
2:19 PM
A bit like LaTeX really...
 
REPL FTW. :)
 
@percusse I used to spend hours customising emacs (before it had a customisation layer) and my .emacs was so big I used to byte compile it, but at some point (I think it was when I switched to windows and started to be corrupted in the ways of the dark side) I just stopped and now go with the flow. I used to compile Tex from source as well but I haven't done that for ages either:-)

@DavidCarlisle It's comforting to see that you also have a pragmatic side heh.

@DavidCarlisle And you use arara too. :)
 
2:51 PM
So Git too is from Linus Torvalds.
 
3:12 PM
@percusse at least, he used OpenOffice Impress for his keynote. :)

Q: Open source workflow to represent a number in a table cell by its background color

ChristianI know this isn't strictly speaking a LaTeX question, so please move this somewhere else if you feel like it. I find large tables of numeric values a bit hard to comprehend at a glance ... or even many. One strategy to alleviate this is to set the hue of the background color according to the val...

 
@tohecz Voted and closed. :)

Q: Strange highlighting in LaTeX-Suite

szsdkI use Vim 7.3 and LaTeX-Suite 1.8.23. But every time when I use the function in LaTeX-Suite , such as $e^^ and amsmath<F5>, the whole source code will be highlighted. How to fix it up?

 
@egreg :)
In fact, I tried Vim-LaTeX now and my guess is that his Vim colour scheme is messed up.
It seems to work quite well for me, although I'm allergic to Vim-LaTex. :)
@egreg: someday we will have minerva. :)
 
Great news! A student of mine brought here his sister for some consulting about her thesis in LaTeX. The problems were solved and I earned a bottle of Valpolicella. :)
 
kan
@egreg Aw! How nice! :)
 
4:14 PM
@egreg How nice! LaTeX and a good wine! :)
 
 
1 hour later…
5:31 PM
oh look, a new package:-)
4
 
@DavidCarlisle Nice. What does the P. stand for, if I may ask?
Better yet, what's your middle name?
 
@GonzaloMedina 10 bucks on "PowerPoint". :)
 
@GonzaloMedina mostly it's used so I can get a google id with an approximation to my real name rather than a random string of digits at the end. I believe my passport says it stands for Paul but it doesn't get used much:-)
 
@DavidCarlisle Paul OMG!
 
@DavidCarlisle New package, new bugs!
 
5:36 PM
PowerPointCereda
 
@egreg hehe!
 
@egreg The full package documentation is "not usable yet" so the only bug report would be a user error, if someone uses it.
 
@DavidCarlisle We'll anxiously wait for the release to discover its undocumented features. :P
 
@DavidCarlisle <3
 
@egreg maybe it'll be like colortbl and go for a decade or more between 0.x and 1.0
 
5:40 PM
I have one middle name and another surname, poor me. :)
@DavidCarlisle: do you know the full name of Pedro I of Brazil? :)
 
@PauloCereda What's your surname?
 
@GonzaloMedina I have two: Massa (mom's) and Cereda (dad's).
And there's a Roberto (middle name) after Paulo. :P
 
@PauloCereda everyone knows that: Pedro de Alcântara Francisco António João Carlos Xavier de Paula Miguel Rafael Joaquim José Gonzaga Pascoal Cipriano Serafim
 
@DavidCarlisle OMG
 
@DavidCarlisle Most certainly Wikipedia knows. :)
 
5:43 PM
@egreg do you suspect I can't actually type that many words in that time:-)
 
@DavidCarlisle: The only problem is that the English Wikipedia missed the last part: de Bragança e Bourbon :)
 
@PauloCereda Ah, I got confused; I thought you had a first name, a middle name, yet another name and then the last (family) names; that's not so uncommon amongst Spanish descendants.
 
@GonzaloMedina Ah interesting. :)
 
@GonzaloMedina Spanish uses the reverse order for family name, I believe.
 
@PauloCereda That is the problem with plagiarism it sometimes leaves a trail that may be followed
 
5:45 PM
@egreg We use first the father's last name and then the mother's last name; in some countries (Argentina, I believe) the parents can decide the order; in Colombia there's a proposal so that the order can be optional too.
 
@DavidCarlisle Indeed. :) A friend of mine got excommunicated from a course because he CTRL+C/CTRL+V a text from a(n European) Portuguese source. One of the members of the committee found the word "Ficheiro" which we never use it here (we use "Arquivo" - means "File").
 
@PauloCereda CTRL C ? He should have used emacs
 
@DavidCarlisle Or Vim: y
:P
Let's reopen the question for an emacs answer. :)
 
@PauloCereda yes I saw that and hoped it would get closed before I was tempted to answer.
 
@DavidCarlisle I have a Windows machine near me and I typed edit in the prompt. That nasty editor still exists! :)
 
5:51 PM
@PauloCereda not on my machine apparently
 
@PauloCereda Ha! That's also a way to detect someone's origin; we in LatinAmerica use "archivo" but in Spain they say "Fichero".
 
@DavidCarlisle Really?! Windows 7?
 
:6971490 yes win7 64 bash: type: edit: not found or if I find the windows cmd prompt (once in a lifetime:-) then 'edit' is not recognized as an internal or external command,
operable program or batch file.
 
@DavidCarlisle Ah mine is 32 bits.
 
6:37 PM
@JosephWright: Are you around?
 
@PauloCereda he left a comment 12 minutes ago in one thread...
 
@tohecz Oh. :)
 
Hi guys. Do you notice the new package etoc? Sounds interesting -- ctan.org/pkg/etoc
 
6:57 PM
@MarcoDaniel And we thought we were eccentric. :) The package name is always typeset in red. :P
 
@PauloCereda Maybe ;-) Is the author a member of tex.stackexchange?
 
@MarcoDaniel Dunno.
 
@PauloCereda Hello
 
@PauloCereda What?
 
@MarcoDaniel "I don't know". Contracted form. :)
@JosephWright Hi! :) Can I ask a newbie question about biblatex? :)
 
7:00 PM
@PauloCereda Yup
 
@PauloCereda You are my English teacher. I have learned TLDR and now Dunno ;-)
 
@MarcoDaniel <3
@JosephWright Henrique and I were working with biblatex and ABNT. At a certain point, we have something like this:
 
:6972485 OK, Biber features
 
Hold on, code must be indented. :P
\step[fieldsource=title,
    fieldset=shorttitle,
    match=\regexp{(\w+)\s+(\w+).*},
    fieldvalue={$1}]
We tried to have {$1 $2} in the fieldvalue, but we could not achieve that.
What I did was to replicate the step and then append $2 later to that field.
@MarcoDaniel It's a Perl replacement, I guess. It should work. :)
Let me give some background. With ABNT, when an entry has no author, part of the title becomes "the reference". For example, The book of the thousand nights and a night would become The book (according to the regex, $1 $2).
 
@PauloCereda I believe we need a mwe for playing ;-)
 
7:07 PM
@MarcoDaniel I have one, but... should I? :P
@MarcoDaniel: We could come up with (offensive) "MWE or GTFO". :)
 
@PauloCereda You are right. I found the correct hint in the documentation:
•If match is defined but replace is not, only apply the step if the fieldsource ⟨entryfield⟩ matches the match regular expression29. You may use capture paren- thesis as usual and refer to these ($1. . . $9) in later fieldvalue specifications. This allows you to pull out parts of some fields and put these parts in other fields.
@PauloCereda What?
 
@MarcoDaniel It's a slang. It means "____ or get the f* off". :)
 
@PauloCereda Too many abbreviations for this evening ;-)
 
@MarcoDaniel Exactly. :) So far the code works, but I'm failing at concatenating values in the fieldvalue. :)
@MarcoDaniel Indeed. :)
 
@PauloCereda Please try:
\step[fieldsource=title,match=\regexp{(\w+)\s+(\w+).*},final]
\step[fieldset=shorttitle,fieldvalue={$1 $2},append]
 
7:11 PM
ooh let me check.
 
@PauloCereda Adapted from an example of the documentation -- didn't test
Is there an abbreviation for "didn't test"
 
@MarcoDaniel Sadly it didn't work. I get the same error as before.
! Extra }, or forgotten $.
<recently read> \egroup

l.134 \citetitle[1]{1001nights}
 
@PauloCereda You may use capture parenthesis as usual and refer to these ($1. . . $9) in later fieldvalue specifications. -- it's from the doc
 
@MarcoDaniel I did. Parenthesis are used in the match=\regex to set which parts I want, then if I refer either $1 or $2 in the fieldvalue, it works, but not both.
 
@PauloCereda Ah -- I see
@PauloCereda Can you upload the bib-entry
 
7:19 PM
Wait a minute, this might be a Perl code, so I need to concatenate two variables!

@MarcoDaniel: you know the workflow: pdflatex, biber, pdflatex )
 
@PauloCereda THanks-- great advice ;-) -- Normally arara do the job for me ;-)
 
I want to evaluate expressions to populate different entries in a table. Sagetex is the most powerful way I have come across. But I guess I need to install Sage on my computer along with the Sagetex package. Therefore I was looking for alternatives. Any ideas?
 
@JosephWright: I think it's biber that expands those values, is this correct?
 
@PauloCereda Sounds right, but @PLK is the expert

Are our mathamatitions in the house? Someone tied LaTeX in with some Javascript and tried to get a paper submitted...and suceeded:
 
@MarcoDaniel Thanks, it works. Actually, I did the same trick, but I'd like to understand why {$1 $2} doesn't work. :)
 
@PauloCereda Understanding is overrated
 
@MarcoDaniel LOL
 
The first math paper I've written in latex this century, pretty impressive co-authors too : UNIQUENESS IN FORMAL LOGIC
DAVID CARLISLE, R. MÖBIUS AND O. PEANO

@DavidCarlisle Yeah, this has been done a few times.
 
7:44 PM
@DavidCarlisle I thought you'd write a paper with @egreg. :)
 
@PauloCereda I'm waiting for him to learn Word
 
@PauloCereda If you know a solution please tell me ;-) -- Maybe you can ask a question. I think it's an interesting question which can be important for other users
 
@MarcoDaniel I'll try to come up with a simple example. I don't want to post this huge file. :)
 
@DavidCarlisle I went for A. N. Other and D. Nobacon :-)
@DavidCarlisle No Erdos?
 
@JosephWright Erdos has a Carlisle number of 3. :)

7:52 PM
@PauloCereda I suspect we want either DEK or LL numbers :-)
 
@JosephWright True. :)
 
@JosephWright well I didn't pick, they chose me.

@DavidCarlisle Are you trying to take all of the starred spaces?

@DavidCarlisle You did the figures with picture mode. :)
 
@PauloCereda No I left the graphics to my co-author MÖBIUS but he has this irritating habit of using both sides of the paper at the same time.

@PauloCereda My Erdős number is 3.
:)
 
@PauloCereda typical:-)
 
If I try to compute my Erdős number, the application will have a integer overflow.

@DavidCarlisle :)
 
@DavidCarlisle What are those numbers about?
 
8:11 PM
@JosephWright the ones in brackets, links into math reviews
 
@DavidCarlisle Ah, right

Q: Concatenating regex variables in fieldvalue

Paulo CeredaFriends, I'm stuck with a doubt about how to concatenate values from regex parenthesis into the fieldvalue mapping option. Let's see a quick working example: \documentclass{article} \usepackage{filecontents} \begin{filecontents*}{\jobname.bib} @book{fruits, title = {The apple and the banana},...

Worst bibliography entry ever. :P
 
! Undefined control sequence.
l.18 \DeclareSourcemap
do I have an old biblatex?
 
@DavidCarlisle Really? It works for me. :(
@DavidCarlisle Maybe it's an old biblatex install. :(
 
8:25 PM
I have TL2012 but trying tlmgr update biblatex
see what happens
 
hhh
What is this classic err here, undefined control sequence with equation?
 
@PauloCereda ah now it works
 
hhh
Should I use some equation package for \text{...}?
 
@hhh \usepackage{amstext}
 
hhh
@JosephWright Thank you, worked.
 
8:32 PM
@PauloCereda grmble now it says I need to do $ tlmgr update biber
@PauloCereda I should have stuck to bibtex
data source /tmp/par-davidc/cache-8eaa473e710cf88586c3ecec6aadfd9638ffc6da//inc/lib/Biber/LaTeX/recode_data.xml not found in .
Compilation failed in require at Biber/Utils.pm line 20.
 
@PauloCereda My Erdos number will be 3 as well soon ;) (my supervisor has 2)
 
@DavidCarlisle Unpacking failure. Delete this cache directory
 
@JosephWright thanks I guess that worked, biber has gone into one of its long sulks
 
@DavidCarlisle oopsie. :)
@tohecz How nice! :)
@DavidCarlisle: I'm suspecting that the regex/Perl variable expansion is done by biber.
 
@PauloCereda I'm sure of it
 
8:40 PM
@PauloCereda biber still hasn't finished thinking about your document....
 
@JosephWright Ah.
 
@PauloCereda Certainly not programmed into biblatex
 
@JosephWright Forgive me, I'm a newbie. :)
 
hhh
Newbie err: illegal character in array here, ideas?
 
@PauloCereda but the problem is that it is not recognized, because her paper with Vojtech Rodl has her surname before marriage.
 
8:42 PM
@tohecz Well, at least you know the truth. :)
 
@tohecz Not automatically, but should be accepted by the Erdos number project I'd imagine
 
@JosephWright yeah, but the thing is: she doesn't care :p
 
I was looking through their list of Nobel Prize winners to find a route to some chemists
 
@hhh Its much easier to answer these if you show the code in an example in a question on site but most likely you have \begin{array}{ccc?cc} with some character like ? that is not a defined column type
so if I delete the cache file just how long should I leave biber before kill -9
 
@PauloCereda hi Paulo! nice question :) have you tried replace={\refexp{$1~$2}}, or is that something different? :)
 
8:47 PM
@cmhughes Hi Chris! :) For my simple example, replace works like a charm, but I really need a solution involving fieldvalue. :)
 
@PauloCereda oh, ok :) no idea at the moment then...
 
@JosephWright We could find people with low numbers and make some unholy arranged marriages. :)
@cmhughes replace would work like a charm if we didn't "copy" the value from one field to another. :)
 
@PauloCereda ok, I'll have a look at it- not sure if I'll get anywhere though :)
 
@PauloCereda I'm more interested in getting a link to Justus von Liebig :-)
 
@JosephWright Wow! :)
 
8:50 PM
@PauloCereda Tricky: I have a couple of ideas :-)
 
@cmhughes The "boring" part is that once an error occurred, it's propagated to every auxiliary file, including biber's. :)
@JosephWright ooh! :)
 
@PauloCere biber stull hasn't finished but if I change the $2 to $1~$2 then the .bcf file ends up with map_field_value="$1\nobreakspace {}$2"/> which might not have the desired meaning if used directly in perl, what happens if you just use $1 $2 ?
 
@DavidCarlisle It doesn't work. :(
If the field has only one $ variable, it works. Even aaaaaa$1 works. But not with more than one variable.
I think only PLK knows the key to the secret. :)
I must confess, the World Cup mascot is very cute. :)
 
9:18 PM
Nice findings on Math.SE

Q: What's the derivative of the integral of $\sin(t) \text{d}t $ from $1$ to $x$?

IanWhat's the derivative of the integral of $\sin(t) \text{d}t $ from $1$ to $x$? Any ideas? I'm getting a little confused.

An almost 400 year old theorem.
 
@egreg Quite new, then ;-)
 
@egreg Oh my!
@JosephWright: Maybe you could write an answer about ltnews here: :)

Q: left justifcation only similar to the LaTeX3 newsletter

AA2007rHow does one gets a layout similar to the LaTeX3 newsletter? Specifically, the text is left justified only and I cannot figure out how. I have tried raggedright/raggedleft commands without success.

 
@JosephWright When I talk to my classes about the infinity of prime numbers, I ask them if the think the result is more or less than 100 years old; then I increase to 200, then 400, then 1000. Eventually many are surprised to discover it's about 2300 years old.
 
@egreg Ah right. I was thinking more of Pythagoras than Euclid, but there we are
 
Would Erdős' advisor have an Erdős number of -1?
 
9:26 PM
@JosephWright Another surprising fact is that here nobody is taught Euclid's algorithm for the gcd, in middle schools, but rather they do the computation by factorization. I guess that something that's been known by mankind for 23 centuries should be not so hard to grasp even for kids.
 
@egreg I learned by factorization.
 
@PauloCereda Maybe with tables of factorization and prime numbers at the end of the book.
 
@egreg We didn't have tables. :(
I learned Euclid's later on.
 
It's quite fun that 1999, 2999 and 4999 are prime (our tables were up to 5000). Also 8999 is; 16999 isn't.
 
@JosephWright If I want to serialise some LaTeX3 stuff to the aux file, presumably I need to put in \ExplSyntaxOn and \ExplSyntaxOff either side of it, right?
 
9:35 PM
@AndrewStacey For the .aux file, either that or \csname\detokenize{<name>}\endcsname
@AndrewStacey I would not do this, though :-)
@AndrewStacey Standard LaTeX commands for the .aux are all 'public' (no @)
 
@JosephWright \select@language? But that's babel, of course.
 
@JosephWright Oh. I want to provide a way for someone to save a Hobby path definition to avoid having to regenerate it every run. I've serialised it to a token list so I can save it and reread it within a single run, but I'd like to be able to save it between runs. Should I rename everything with "normal" names, save that, and then on rereading convert back to L3 names?
 
@egreg I meant specifically stuff in latex.ltx, so designed by Leslie
@AndrewStacey I'd use a separate file, myself
 
@JosephWright Yes, I know. However the .aux file is read under \makeatletter
 
@AndrewStacey Does the TL itself contain L3 commands?
 
9:38 PM
@JosephWright Here's my serialisation:
 
@JosephWright But what about \@writefile?
 
\g_hobby_path_path=macro:
->\int_gset:Nn \l_hobby_npoints_int {2}\bool_gset_false:N
\l_hobby_disjoint_bool \bool_gset_false:N \l_hobby_closed_bool \array_gclear:N
\l_hobby_points_array \array_gput:Nnn \l_hobby_points_array
{0}{x=0,y=0}\array_gput:Nnn \l_hobby_points_array {1}{x=1,y=1}\array_gput:Nnn
\l_hobby_points_array {2}{x=2,y=0}\array_gclear:N \l_hobby_actions_array
\array_gput:Nnn \l_hobby_actions_array {0}{10}\array_gput:Nnn
\l_hobby_actions_array {1}{10}\array_gput:Nnn \l_hobby_actions_array
So, yes. It contains L3 commands.
 
@egreg OK, perhaps not everything :-)
@AndrewStacey As I said, you either need \ExplSyntax guards or can use a separate file plus \ProvidesExplFile (read with \@onefilewithoptions). Speaking of which, I'm about to fix an issue with the latter approach in the CTAN release!
 
@JosephWright Okay, I'll ponder a bit.
 
hhh
@DavidCarlisle pastie.org/5414550
@DavidCarlisle it is the code that is firing the mistake to chat.stackexchange.com/transcript/message/6974030#6974030
Err here.
 
9:51 PM
@hhh It should be \begin{array}{c}
 
hhh
@egreg thank you, fixed :)
