@PauloCereda With your kind permission i gladly would present your voice arara. It's a nice intro. Thanks tug-uk. May be you should make some more.

Sorry for interrupting. I have no idea rather than using multicol to wrap the inner enumerate to get the following result. Is there a better way?

\documentclass[preview,border=12pt]{standalone}
\usepackage{enumerate}

\begin{document}
\begin{enumerate}
	\item What is $y'$ for $y=x^n$?
	\begin{enumerate}[(a)]
		\item $nx^{n-1}$
		\item $xn^{x-1}$
		\item $x^{n-1}$
	\end{enumerate}
\end{enumerate}

\end{document}

Sorry, I am late to edit. Here is the final.

\documentclass[preview,border=12pt]{standalone}
\usepackage{enumerate}
\usepackage{multicol}
\begin{document}
\begin{enumerate}
	\item What is $y'$ for $y=x^n$?
	\begin{multicols}{3}
	\begin{enumerate}[(a)]
		\item $nx^{n-1}$
		\item $xn^{x-1}$
		\item $x^{n-1}$
	\end{enumerate}
	\end{multicols}
\end{enumerate}

\end{document}

No comment means no other way. Thank you.

@Karl'sstudents Wild guess: If you are setting an exam paper Multiple choice then exam class exsheets can do without any tweaking.

@texenthusiast I have not used it yet.

@Karl'sstudents If you can bear with me posting a related Q

@texenthusiast Where is your posting?

@Karl'sstudents tex.stackexchange.com/q/15480/15717

Does ExSheets supersede the other old document classes or packages with roughly the same objective?

@Karl'sstudents both are by different authors no supersede

ExSheets seems sophisticated.

Yes

@Karl'sstudents Looks like the inner list you want to set as a horizontal list rather than vertical, there are packages for that paralist or some such name I think.

@DavidCarlisle OK. Thank you.

@texenthusiast Someday, perhaps. :)

@PauloCereda: "my english is poor my heart is rich" ;-)

@MarcoDaniel :P

@PauloCereda You English is great. I understand you ;-)

@MarcoDaniel Wow.

hi again

don't know who's still in here of those who were in here before

I've got a follow up question:

how do I achieve the equivalent of

@nuttyaboutnatty I don't know nothing about tabu. ;)

` \begin{tabulary}{0.7\textwidth}{LCL} `

in tabu ?

(I'm a beginner, as you will notice... ;)

I've tried massaging this one:

\begin{tabu} to \linewidth {X[-1,l]X[-1c]X[-1l]}

@nuttyaboutnatty Avoid tabu see: tex.stackexchange.com/questions/107012/…

ok...

almost convinced to drop it (the warning of not to use it keep piling up...)

yet en.wikibooks.org/wiki/LaTeX/Tables "still" advocates it as a revelation

ok... so I'll drop it

back to square one

I'll use the "p" to make sure my columns stay nicely put (wrap, no "overflowing")

@MarcoDaniel: You need to update your image. Put the German Avatar. :)

@PauloCereda Should I?

@MarcoDaniel <3

@nuttyaboutnatty If you show us an image of your table, maybe we can give you possible alternatives. tabularx is always helpful.

Hey guys, I was wondering if you knew how to fix a overfull \vbox error?

@nuttyaboutnatty really as a beginner I'd start with tabular and get the syntax of that understood and then just move to extension packages if you need them. They all have edge cases and problems here and there, but if you know how the core code works then you can use any of them. (An exception being array package that is a core part of latex so you should just load it anyway, the only reason it isn't part of the format is compatibility with latex2.09 Ie documents written before 1993)

@gekkostate don't put so much in the box.

@Karl'sstudents How about:

\documentclass{article}
\usepackage[load-headings]{exsheets}
\SetupExSheets{headings=runin-nr}
\begin{document}

\begin{question}
What is $y'$ for $y=x^n$?
\begin{tasks}(3)
 \task $nx^{n-1}$
 \task $xn^{x-1}$
 \task $x^{n-1}$
\end{tasks}
\end{question}

\end{document}

@DavidCarlisle So what can I do make sure that isn't so much in the box?

@gekkostate go on, give us some clues In particular is it an overfull box in the output routine?

@cgnieder I got the following:

@DavidCarlisle Sorry, I understand what you mean by "output routine".

@DavidCarlisle LEGO box. :)

@gekkostate did the error say overfull....in the output routine

@PauloCereda that box is overfull as is the living room:-)

@DavidCarlisle sorry, yes. It said "Overfull \vbox (13.59999pt too high) has occurred while \output is active []"

@DavidCarlisle :)

@Karl'sstudents You have a version with a bug, v0.8, I guess. Add

just for practice purposes:

\ExplSyntaxOn
\cs_new_eq:NN \seq_length:N \seq_count:N
\explSyntaxOff

how do I get the same result with plain-vanilla tabular ?

@gekkostate so either it is the page head or foot and you have allocated (say) 25pt for the headline and put a 39pt high picture in there, or it is the main page in which case there are large unbreakable things on the page and tex left it sticking off the end. It's usually obvious from the output.

I'd expect p{'width'} to be needed

@cgnieder and @texenthusiast: OK. I successfully compile it. Nice! Thank you!

@nuttyaboutnatty you drop the {0.7\textwidth} and use` lcp{3cm}` where the 3cm is a guess that you change by eye

@texenthusiast: could you join the tikz and pstricks room now? I need you to test my code.

@Karl'sstudents sure

@texenthusiast This room : chat.stackexchange.com/rooms/7828/pstricks-and-pgf-tikz

@nuttyaboutnatty If you do that a few times you understand the syntax and then can see what tabularxy/tabu are doing (they do literally just use a normal tabular and p{..} columns underneath.

@cmhughes: Any plans for getting a Wii U? :)

@DavidCarlisle can "p" also take right, center, justified arguments?

in the tabulary-example I gave above both the first and 2nd column look like "p"

@nuttyaboutnatty with array package (which as I say you should assume, and most of the others load it anyway) >{\raggedright\arraybackslash}p{..}

@nuttyaboutnatty in general > and < can inject any commands into each cell so raggedright or color or font changes or >{hello} would add that text at the start of every entry

I'm still hesitant about which to use (I've at last and at least dropped tabu): tabular vs tabularx vs tabulary

which one is "best" ?

is tabulary more recent (and better) than tabularx ?

also, if I could avoid those "manual" commands with arrays and inequality signs (I can follow the syntax in your example!) by simply using tabulary - why not to use tabulary?

@DavidCarlisle from their resp. documentation I gather that tabulary is newer by almost a decade

So I guess it's now down to tabular vs tabulary

@nuttyaboutnatty Both have very unreliable authors, don't believe a word he says.

;)

/me just got 400 bounty - getting closer to @PauloCereda' CC number (I can almost feel it!)

@topskip oh no! <3

@nuttyaboutnatty more seriously I think you are approaching this from entirely the wrong angle. If you are writing your thesis the important thing is the data, and the data is always marked up the same way rows separated by \\ and entries by & . Changing a document from tx to ty to tabu to array package syntax is just a few minutes work with a reasonable editor and there is anyway no need for all tables to use the same package, they don't conflict you can load them all.

@DavidCarlisle Speaking of which, what is the preferred way to put \textbf{ and } without invoking \bfseries without making the table gods of TeX angry?

Hmm, example is lame. Let's make it math mode tilde \widetilde{ and } around the cell content?

@percusse you mean you want a tilde over every cell?

Yay, my category theory book is en route!

\def\foo#1\wibble{\widetile{#1}} ... >{\foo}c<{\wibble} but it doesn't work in the last column.

I miss @egreg. :( Where is he?

@DavidCarlisle Well more like, I want to send the cell content to a macro. But >{\tilde\begingroup}c<{\endgroup} won't cut it right?

@percusse see above. If you need the last column it's a bit harder

@DavidCarlisle the data's there; in *.xls files (which, as I learned today tex.stackexchange.com/a/108070/27721 can be copy-pasted through a wizard in Kile); I'm just trying to get the style I like (and be able to (mostly) forget about it henceforth).

@DavidCarlisle Ah I see thanks. The last column is the \arraybackslash wizardry if I remember correctly.

@nuttyaboutnatty ah well you're forgiven then:-)

@percusse wibble.

I know I'm infinitesimally slow in realizing my desired table, though :(

@PauloCereda \bar is getting out of fashion

@percusse Sounds like a task for Martin Scharrer's collcell package

@percusse Knights of Foo Bar. :)

@cgnieder Oops. Of course. :)

@percusse well related but harder to deal with, & is a primitive and ends teh cell even when tex is scanning for the argument of \foo so it sees \wibble and teh macro works, but \\ is just a macro so doesn't do that and your whole document gets eaten. You can use \cr instead. or you can make the macro be delimited by \\ or ...

@cgnieder I was going to say Martin or Heiko or someone had a package (someone always has a package)

@DavidCarlisle very true :)

I mentioned Blackadder. Where's @JosephWright? He usually appears in the chatroom when we have Blackadder or Monty Python stuff going on. :)

@DavidCarlisle Does tabulary support "define many identical columns at once using the *{''num''}{''str''} syntax" ?

@PauloCereda and this scene is a classic :)

@cgnieder Indeed! :)

Me TeXing or reading manuals. It's an almost 100% match

yes it does...

:)

@nuttyaboutnatty If you've got data in *.xls files, you could try exporting them to csv files and use datatool to display the data.

what exactly is datatool? I've seen it being mentioned here and there...

@nuttyaboutnatty here it goes ctan.org/pkg/datatool

a bit overwhelming... why would I want to use it?

(at this stage, I think I might not need to do any plots; tables of data might suffice)

@nuttyaboutnatty Yes that's handled at a different layer before the individual column types are looked at. So in a way no it doesn't handle it, it doesn't need to (same is true of TX)

@nuttyaboutnatty What a thing to say, @NicolaTalbot is probably devastated now:-)

@DavidCarlisle :-)

@nuttyaboutnatty dont be overwhelmed just dive into deep TeX waters even if its freezing cold :)

shivers.... ;)

@nuttyaboutnatty only first few min later you get used to.

haha

hmm, these minutes kind of feel like HOURS

@PauloCereda Yo!

@JosephWright Hello! We miss you! :)

@PauloCereda Had to go shopping :-)

@JosephWright :)

@NicolaTalbot Madam, with your kind permission, I have some suggestions on latex resources page : prosper is outdated and merged with powerdot as per herbert comment and miktex installation video can be changed to may be this one if you like. Thanks

can someone plz help me make this

from the ctan.org/pkg/siunitx doc

into a MWE ?

I tried

(and get error(s))

@nuttyaboutnatty toprule and friends are booktabs commands so you need \usepackage{booktabs}

anyone know a good, simple tutorial for using aux files?

@PauloCereda Hi Paulo :) no immediate plans for a Wii U... how about you? :)

@Luke You don't use aux files, latex does. What do you want to know about them?

@cmhughes Hey Chris! :) I was thinking of getting one, but it's quite expensive right now.

@PauloCereda yes, indeed :) I haven't kept up to date with the 'flagship' games either- presumably Mario?

@PauloCereda have you played Demon's Souls or Dark Souls?

@texenthusiast Okay, I edit the page when I have a moment.

@cmhughes Mario for Wii U is quite beautiful, though it's basically Wii + HD definition. On the plus side, some franchises are coming to Wii U, like Assassin's Creed III and Bayonetta 2. :)

@cmhughes I did. :)

@PauloCereda what did you think? I quite enjoyed Demon's Souls- found it a bit scary though, being ambushed in the dark by skeletons and others

@David, I have listings that specify errors. I'd like to index these errors in a table (e.g., Error1 Listings: 1.1 1.3 4.4; Error2 Listings: 3.4 6.3), and I'm hoping to use custom auxiliary files to do this.

@NicolaTalbot Thanks Madam, i liked your organisation of website and details. Its an excellent effort made by you to service all people. Thanks a lot.

@cmhughes I think it's a great game, though I need to get better with the joystick configuration. :)

What options are there to round (the pdf-displayed) numbers correctly to two decimal places?

@PauloCereda yes indeed- I enjoyed the multi-played aspect too

(currently, I'm doing an Excel array rounding transformation, prior to LaTeX importing)

@DavidCarlisle: someone is starring your messages like crazy.

Short question: How can I draw a flash with TikZ? Does anyone know an answered question?

@PauloCereda That will be @NicolaTalbot trying to erase the record of her bug.

@PauloCereda are you looking at me??

@PauloCereda: How did you do the lightning in your presentation of arara?

@texenthusiast :-)

@DavidCarlisle Not guilty, apart from that one. Couldn't resist it :-P

Oh, I shouldn't have done that. It's put a mention of my bug at the top of the list.

@NicolaTalbot oops another one

@DavidCarlisle :-P

@nuttyaboutnatty We cannot see which person starred what - the only thing we know is that we cannot star our own messages.

(I know)

@MarcoDaniel Hm lighting?

@PauloCereda Yes. I took the wrong word

@DavidCarlisle: H David, I have listings that specify errors. I'd like to index these errors in a table (e.g., Error1 Listings: 1.1 1.3 4.4; Error2 Listings: 3.4 6.3), and I'm hoping to use custom auxiliary files to do this (via starttoc). I don't understand how to distinguish between a first and second pass though---and am not even sure that I need to. Which is why I was looking for a simple tutorial.

@MarcoDaniel It was @Joseph's. It's a screen recording. :)

siunitx seems to offer rounding, but the doc is not v dummy-friendly

is it possible to turn rounding on "globally" for all data in a table, or would all cells need to be edited individually? how?

@Luke You can use \protected@write\@auxout{}{stuff to write to aux file} to write to the aux file.

@Luke ah other files not .aux there really isn't much to say your question above is longer then the latex definition of starttoc and friends:-) latex normally doesn't distinguish between 1st and second passes (doing so makes things fragile in the face of edits to the source` normally latex just writes out definitions and then when the file is read back the definitions are made so as long as you test whether the macro is defined before you use it things work out after a pass or two.

huhu

@Luke Did you want to sort the errors or just have them in order of occurrence?

@DominicMichaelis Hello :-)

@MarcoDaniel: what do you mean "draw a flash"?

@DavidCarlisle, I'm generating labels in order of occurrence, and then defining commands that are just refs to the labels, to use in my index-ish table, so that part should be simple.

@MatthewLeingang I want to draw a nice lightning. Of course I can use the package wasysym and than \lightning

@nuttyaboutnatty set it in the table column.

@DavidCarlisle so my plan is to dump a bunch of appto commands into the file

Oh, I see. Give Mark Wibrow a minute and he'll code you a new pgf node shape...

@Paulo how?

using tabulary, threeparttable and booktabs, all I still need to fix is:

@Luke sorry my imagination is running out. Probably you need to post some input and required output to the site hard to visualise in chat mode descriptions.

a) rounding to two decimal places

b) centering around the dot

I'll throw a round of coffee (or beer) if you guys help me nail this one :)

@DavidCarlisle, it's ok. I'll just do some experimentation to see if I can figure out the timing that things happen. I'll bug you again if I can't figure it out.

how does this \begin{tabular}{S[table-format=3.2]S[table-format=2.3]} from tex.stackexchange.com/questions/85229/… work with tabulary etc ?

@nuttyaboutnatty tabulary is just a normal tabular apart from LCR columns so it should just work Not tried it but what could possibly go wrong? (Blame @JosephWright if anything does)

am trying, am trying... (as fast and efficiently as I can)

@DavidCarlisle am trying to reconcile the above with \begin{tabulary}{\textwidth}{*{8}{L}}

so L and S

or L vs S

@nuttyaboutnatty just replace one (or all) of the L by S doesn't make sense to have both

say again?

(why?)

also, wouldn't / couldn't all columns need to be "S" ?

(if there were only number-cells (and no text-cells ))

@nuttyaboutnatty L columns are parboxes set to an automatically determined width, but the point of a parbox width is to wrap lines and hyphenate words to fit that width. If you have a single number formatted by S then it is as wide as it is and line breaking and hyphenation don't come in to it.

ok...

@nuttyaboutnatty In that case you don't want tabularx or tabulary or tabu and you can erase most of this evening's transcript

but my intuition was kind of correct that it's either S or L but cannot be both (for a given column), correct?

@nuttyaboutnatty well yes syntactically a token can't be S and L at the same time, but semantically I'm not sure what it would mean as a single number isn't something that you ever want to line break to a specified width (unless you are doing bignum integer arithmetic with thousands of digits)

cool

so what remains is a) rounding to two decimal places

@nuttyaboutnatty You probably want to use tabular* not tabular x/y use S and use booktabs for rules.

@nuttyaboutnatty oh siunitx can do that I'm sure texdoc siunitx round appears several times:-)

(my first column generally is text (not numbers))

I know

@nuttyaboutnatty well use l or c

I'm reading that too, jmust trying to understand, "compile" it, put it together...

what's the difference between

decimal places or significant figures in the mantissa ?

3.40 vs 3.4 ?

the penny's dropped for today, thx again for your inputs!

\inputs

Hey @egreg! We miss you! :)

@PauloCereda did you ever find that any of your .yaml files need to end with a blank line? in particular, on Windows?

@cmhughes Hm not that I'm aware of. I might take a look at the spec.

@PauloCereda no big deal- I have found that on Windows I need my .yaml files (for latexindent.pl, not arara) to end with blank lines....

@PauloCereda All the afternoon lecturing. First logic for high school students, then LaTeX.

@egreg Ah. :) Welcome back.

@PauloCereda I knew he wasn't around when @Werner got in a \ooalign answer before @egreg posted.

@DavidCarlisle :)

@Werner You're pasturing in my field. ;-)

@egreg The grass is green in egreg's pasture and wading there is covered under LPPL... :)

@Werner Damn!

Evening!

Does anyone has experience with using iwconfig?

@PauloCereda i've been wondering for a while- should every yaml begin with !config? or is that specific to the arara project?

@texenthusiast me? typo? (fixed thanks)

@cmhughes It's actually a shortcut for marshalling/unmarshalling YAML from/to objects. :)

@PauloCereda ah, that makes sense... do you have any references you'd recommend for further reading, or are they all contained in the documentation?

@tohecz Hello :-)

@tohecz No, I've never heard of it.

@cmhughes You mean, for YAML? Or the marshall stuff? :)

@DavidCarlisle There's another one: \adujustbox ;)

@cgnieder Oh my!

@PauloCereda perhaps both! :)

@tohecz Oh, it's like ifconfig. I haven't used that in a long time.

@cgnieder you can fix that one (can't you?:-)

@DavidCarlisle sure

@NicolaTalbot well, thanks anyways

@DavidCarlisle Thanks @cgnieder

@tohecz Sorry, that's my useless contribution for the evening.

@cmhughes Hm tricky. :) This is for arara's YAML parser and this one is for the YAML spec.

@NicolaTalbot no worries...

@PauloCereda cool, thanks Paulo, you da' man :)

@cmhughes Nah. :)

@cgnieder probably if you search for my answers it is possible there would be other typos to correct:-)

But there are no typos in my questions.

@DavidCarlisle on my next lazy sunday I could start looking for a few :)

@DavidCarlisle there is always typo squad in some time zones :)

@texenthusiast I like to keep them busy.

@DavidCarlisle :)

@NicolaTalbot Is there a video recording of this

@texenthusiast Not as far as I know. @JosephWright do you know?

(I wasn't at the Cambridge one, just a couple of the London ones.)

@NicolaTalbot Thanks. Do you know any video tut that might be use to add this

@texenthusiast I can't think of any other than the ones from the last UK-TUG meeting.

@NicolaTalbot Ok :)

what do you reckon, duplicate?

@cmhughes think so it's a duplicate answer rather than a duplicate question but ...

@cmhughes On the other hand Frank's opus is probably information overload for a beginner question and a simpler answer of "remove it or leave it there" might be appropriate.

@cmhughes did you see my newbie-to-read

@NicolaTalbot Of the courses? No, had too much else to do! Must book next one :-)

@JosephWright There probably wouldn't be a spare socket for a video camera! :-)

@NicolaTalbot :-)

@JosephWright on l3

@texenthusiast Yes?

@JosephWright book on l3 ?

@DavidCarlisle good point- we could do with a noobie float question/answer

@texenthusiast very nice :)

@texenthusiast None at the moment

@cmhughes thanks :)

@JosephWright ok :)

@cmhughes Question wise, more a duplicate of tex.stackexchange.com/questions/8652/what-does-t-and-ht-mean

@TorbjørnT. good observation yes it's a duplicate of that (except Herbert's answer wasn't as accurate as it could be, I just left a comment a couple of years late but...)

@TorbjørnT. the best part? M-x butterfly

@SeanAllred which is now implemented as a standard command in emacs of course.

@DavidCarlisle Of course. There's a predicate to make sure you don't unleash the full power of the butterfly, of course.

Don't know what I would do if I flipped a bit by accident.

@SeanAllred but I was brave

@DavidCarlisle That command is reserved for only the most noble among us

@DavidCarlisle They've never known such control, and they never shall. Infinite cosmic power!!! (itty bitty footprint!)

@DavidCarlisle :sBm

@PauloCereda but does it work or is that just wishful thinking?

@DavidCarlisle Maybe. :)

@DavidCarlisle :)
