@percusse Oh, a pizza pineapple!

Finanlly :)

@JosephWright Congrats! :)

@JosephWright you should have inserted more bugs

@DavidCarlisle I'm sure I am

@DavidCarlisle @JosephWright Aren't you wedding watching today?

@CarLaTeX Not if I can help it

@CarLaTeX are you getting married?

@CarLaTeX I am going to a wedding in about 10 days ...

The top contributor at MathOverflow is going to Oxford

@DavidCarlisle I haven't found my prince yet

@JosephWright Enjoy!

@DavidCarlisle I see upTeX was updated in W32TeX: I suspect \expanded is there too :)

how can I completely remove texlive 2017 from a unix system to install 2018?

@Aurelius Just delete the directory

@JosephWright just this /usr/local/texlive/ ? I thought there were other files laying around

@Aurelius There's some dynamic stuff in ~/.texlive2017, but its usually tiny

@JosephWright thanks

@DavidCarlisle FAQ ... hmm

@JosephWright it would be easier if it was just on gh-pages and made itself via travis:-)

@DavidCarlisle Yes

@DavidCarlisle That's more-or-less what I'm going to suggest when I write back (a bit busy ATM)

@DavidCarlisle Just need to get hold of the DNS record

@DavidCarlisle I think if we want it to remain useful we need to do that

@JosephWright I think (as with latex-project) there were issues over redirects (which are a bit restricted with gh-pages) but having a usable build system seems more important

@DavidCarlisle Like I say, I think to stay useful we will need to sort this: might have to bite the bullet on redirects

@DavidCarlisle I'll perhaps start on something a bit later today, unless you beat me to it: a one-short conversion to Markdown then we can try it out

@DavidCarlisle I think we either change the back-end or give up on updates: I'd rather we kept the FAQ relevant, even if we have to fix a few links

Royal wedding today!

Will they have a duck parade?

@JosephWright yes and you can keep some links, for the openmath spec, which has some incoming links from mathml spec which I didn't want to break I made directories in gh with an index.html that does a meta redirect. It's asecnd class redirect as it happens in the client not at the server but since gh doesn't offer server redirects it works well enough

@PauloCereda where? in Rio? I didn't know you had a royal family

Why don't we make latex to download packages on demand? Instead of downloading 5 GiB of data when installing texlive, couldn't we make latex download packages when the current document requires them?

@DavidCarlisle I meant the one in the UK. :)

and then cache them

@Aurelius miktex does that but it has other issues

@PauloCereda Hi Paulo! Sorry I missed you 13 hours ago (not sure if 13 hours ago represents yesterday for you, it does for me) :)

@Aurelius you don't have to install the full set a minimal texlive install is a lot smaller than that.

@cmhughes Hi Chris! No worries, pal! Good to see you around!

@PauloCereda you too! I enjoyed your video with the lion puppet :) will you be releasing arara 4.0 at the conference?

@cmhughes Yes, that's the plan! I am writing the manual (finally).

@PauloCereda don't forget to write the thesis first

@DavidCarlisle oh no

@PauloCereda ace, that's very exciting!

@cmhughes It is! I have a very nice surprise for TUG about arara! Did you see our new logo?

@PauloCereda that is stunning! really nice work!

@DavidCarlisle I'll mail later

@JosephWright ok

@cmhughes Surprise by email. :)

@PauloCereda brilliant :) like that a lot!

@cmhughes Thanks, it will be fun. :)

I got this error while installing texlive

@Aurelius a bit odd but sometimes the ctan mirrors do not quite catch up, it should pick up the file next time you update

@DavidCarlisle thanks, I am rerunning since it also said

@Aurelius if it keeps failing you could try a different mirror, there are plenty of Italians here who could tell you the most reliable ones in that area.

@DavidCarlisle The most reliable Italian mirrors are German.

@yo' ooh

My TL repo is always set to Oxford.

@PauloCereda hi pal!

@yo' Hi Tom!

@PauloCereda geography not your strong point

@yo': cake? :)

@DavidCarlisle I wanna be English.

@DavidCarlisle: can I be English?

@DavidCarlisle oh nein

@PauloCereda waffles for breakfast?

@yo' ooh I never had waffles

I only know them because of movies

@PauloCereda are you kidding me? How can you live without snow and home-made waffles?

@yo' I really don't know what a waffle is. :)

@PauloCereda try Uncle Google :) google.cz/search?q=waffles

@yo' ooh

They are a bit pancaky, but smaller and also more lightweight

is there any difference \left( vs \bigl( ?

@Aurelius Yes, the first one tries to determine the right size for the following part.

@Aurelius \bigl is a fixed size

thanks guys so what's the difference between just ( and \bigl(

I though that ( was fixed already

@Aurelius \bigl( is bigger

@Aurelius there are a range of fixed named sizes big, bigg, Big, Bigg etc

@Aurelius See here: tex.stackexchange.com/questions/173717/…

@egreg 24 to go :)

@DavidCarlisle I wished the names were big, bigg, biggg, bigggg. Then I wouldn't always confuse the order ;-)

@UlrikeFischer funny how @DavidCarlisle proved us how easy it is to get confused :)

@yo' lexicographic not size order

@egreg @CarLaTeX «20 (maggio 1518) ... Fo San Bernardin (...) et heri fu messo la palla granda di l'altar di Santa Maria di Frati Menori suso, depenta par Ticiano, et prima li fu fato atorno una opera grande di marmo a spese di maistro Zerman, ch'è guardian adesso» (Marin Sanudo nei suoi Diari). My husband claims that this event (exactly 500 years ago) was probably slightly more important for the history of mankind than whatever will happen today at Windsor Castle.

@UlrikeFischer LOL

Royal ducks

@UlrikeFischer Don’t tell it to @DavidCarlisle. Have you ever seen that painting? It’s great.

@DavidCarlisle what is the best place to insert a hook in every row of a tabular? I feel like \patchcmd\@xarraycr{\cr}{\cr\myhook}{}{}
\patchcmd\@xargarraycr{\cr}{\cr\myhook}{}{}
\apptocmd\@yargarraycr{\myhook}{}{}
\patchcmd\@@array{\cr}{\cr\noexpand\myhook}{}{}
might be a bad idea...

@Skillmon \everycr?

@JosephWright didn't know that one. How robust would it be to use that?

@Skillmon Depends exactly what you want to do

@egreg yes we spent all together more than four weeks at venice on three occasions and naturally saw the assunta.

@JosephWright basically put something in there depending on the current row count (I patched a count into \@arraycr) which most likely needs a \noalign (\rowcolor, \hline, to name a few)

@PauloCereda ^^

@JosephWright but isn't \everycr cleared by tabular because of the inner \ialign call?

@PauloCereda ^^^

@CarLaTeX ooooooh

@yo' ooooooh

I noticed that apparently a former very active user os now deleted (user139954). Do you know who the user was?

@PauloCereda @yo' here our local version:

@Dr.ManuelKuehner Yes: can't say

@JosephWright Ok. Thanks for the reply.

@UlrikeFischer ooh

@CarLaTeX, @yo', @UlrikeFischer: I never had this. :(

@PauloCereda ^^^^

@UlrikeFischer ooh das Wafflemachinen

@PauloCereda ;-) Das Waffeleisen.

@UlrikeFischer I got the plural right, at least. :) PROGRESS! :D

@PauloCereda are you really learning German?

@UlrikeFischer Waffeln mit heißen Kirschen und Sahne? Jetzt habe ich Hunger, obwohl ich gerade erst ein Teilchen gegessen habe.

@PauloCereda Except that you should add a s in there ;)

@PauloCereda das Waffeleisen (one), die Waffeleisen (plural), die Maschine (one), die Maschinen (plural).

@TeXnician ooh :)

@UlrikeFischer ooh

Die Apfel, Die Äpfel

@PauloCereda Der Apfel, die Äpfel

@PauloCereda Der Apfel, die Äpfel ;-). I think the only one where you can be sure is that "das" in singular, but for the rest ...

@Skillmon Oh

@UlrikeFischer oopsie

@PauloCereda isn't it obvious, that apples are male, while cherries and pear are female? :)

@Skillmon o.O

@PauloCereda I think with fruits you're on the safe side if you guess that they are female, except for apples, those are male.

@Skillmon Der Pfirsich.

@UlrikeFischer but most of the time fruits are female, I guess.

@Skillmon Das Obst ;-)

@UlrikeFischer which is no single type of fruit. You know exactly what I meant, don't pick on me :(

@egreg 14 to go

@samcarter looks as if @yo' will win.

@UlrikeFischer Very much so!

@egreg 4 and counting ...

@samcarter If @egreg would ask a question which got one upvote and there would be one downvote, it may work...

@UlrikeFischer 4 points left :)

Give him -3 fast someone ao that he hits the target! :D

@marmot Yesterday I offered, that he could downvote one of my answer to get to switch to a 1/6 cycle, but fortunately this would not help anymore, as there was no accepted answer today....

@Skillmon \@preamble

@samcarter So most likely no one will win because he never hits 654321. @yo' As you have the strongest motivation, I guess the "someone" will be you... ;-)

@Dr.ManuelKuehner You can find out the name from tex.meta.stackexchange.com/questions/7493/…

how can I brake a big sty file in subfiles?

creating other sty files and including them?

@Aurelius creating any other files, usually they would simply get the .tex extension. Just make sure you choose a unique file name. Like mypackage-whateverdescriptionofsubfile.tex

@DavidCarlisle but can I use a \noalign in \@preamble?

@DavidCarlisle I tried patching the \gdef\@preamble{} to be \gdef\@preamble{\myhook} with \myhook set to \relax during \@mkpream, but that one failed, if I remember correctly.

@samcarter @egreg ^^

@Skillmon no

%% Article options
\DeclareOption{10pt}{
  \PassOptionsToClass{\CurrentOption}{article}
}

%% Custom package options
\DeclareOption{sans}{
  \PassOptionsToPackage{\CurrentOption}{custom}
}
\DeclareOption{neverindent}{
  \PassOptionsToPackage{\CurrentOption}{custom}
}

%% Fallback
\DeclareOption*{
  \ClassWarning{myclass}{Unknown option '\CurrentOption'}
}

%% Execute default options
\ExecuteOptions{10pt}

%% Process given options
\ProcessOptions\relax

can you help me understand this?

@Aurelius it is better to ask questions on the question and answer site, but what part do you want explaining

@yo' Was the idea to go 654321?

@FaheemMitha yes

@DavidCarlisle Thank you.

Anyway, @samcarter How good are you at drawing scout scarfs? :)

I use the site when I have bigger questions I have asked 115 already...

should I always use it even for smaller ones?

%% Load base
\LoadClass[a4paper]{article}

%% Load additional packages and commands.
\RequirePackage{custom}

for example why it is doing

%% Article options
\DeclareOption{10pt}{
  \PassOptionsToClass{\CurrentOption}{article}
}

@Aurelius in general yes see:

@Aurelius but "it" (some class you have not shown) is defining a [10pt] option that the user can use but passing it on to articleto be handled

@Aurelius similarly it is defining a [neverindent] option that the user can use which is handles by some package you have not shown called custom.sty

@DavidCarlisle Sounds like it's coming down the wire.

But for some reason, I can't find egreg's reputation.

@Aurelius I assume that was taken from some tutorial example, rather than real code?

@DavidCarlisle en.wikibooks.org/wiki/LaTeX/Creating_Packages

Thanks David you are very kind

@DavidCarlisle That was not well formulated on my end. I meant, can I sneak something into \@preamble which later needs to use \noalign, like e.g. sneak a hook into the \@preamble that later is used to call \rowcolor on the first n lines?

@yo' Sorry for the 7

@Skillmon no, \noalign is used for constructing the internal \halign preamble and serves no purpose after that, and you can't trigger a \noalign in the align preamble so everycr or the laetx \\ are the places to attack

I made an automated build system for latex using node.js and gulp that compiles the bibliography and the tex file as soon as you modify them, and filters the stdout of the compilation removing uncessary things and leaving only the few usefull lines like warnings, underfull and overfull boxes, errors etc. Could that be helpful to be shared?

@Aurelius possibly, personally I like to run it by hand and I like to see all of the log file, but I'm not a typical user, so don't ask me:-) Make it available and see if people use it!

@egreg Some Americans would read a European-style 1 as 7, you only need to find a way to reverse that. Congratulations!!!!

@egreg I think it is time to publish your bet. ;-) I do not have your old landline number.

@DavidCarlisle then I'll keep using what I got so far. Thanks for clarification.

@Skillmon probably you understood but I meant \@preamble not \noalign is used for...

@DavidCarlisle \everycr seems not advantageous, because it is emptied in \ialign, so I'd have to patch the \everycr call after the \ialign in \@array. Patching \@arraycr and its friends seems to be the same effort, since I have to patch them anyway to introduce a row count. And yes, I understood :)

@marmot Let me finish my tour. Last pit stop.

@Skillmon isn't emptying what you want? if you have some compound character using [ihoo]align internally you normally don't want it to pick up the per-row behaviour of the outer tabular

@yo' Congratulations to winning the contest! A scout duck is a great idea - I'm looking forward to draw it!

@yo' Are there some photos available of the scout outfit in your area?

@samcarter I'll keep in touch later

Made 1k rep mark! Whoop

@yo' Take your time!

... which is proof that I'm not really doing what I should be doing during the day.

@DavidCarlisle nah, I hack into all of that so I can put stuff at the beginning of each tabular row which needs \noalign to work (e.g. \rowcolor).

Okay - so I just learned that when I edit questions they show up on the active page. I've been keeping some of my answers "up to date". Especially the answer on this question, since it's in regards to a package I made. My question now is whether or not I should keep updating answers like this since it might draw attention away from new questions. Is it bad etiquette?

@AndreasStorvikStrauman No, provided you don't go made and flood the front page with edits

Yeah - I'll definitely be more mindful about it! Not sure, but I suspect I might have flooded at some point. Heh ':)

@AndreasStorvikStrauman That's a delicate issue if the question got accepted. Even if you think that you made the answer better, others may disagree, and even worse, the solution may no longer work for the OP asking it. And sometimes answers refer to other answers, so dramatic changes could lead to confusion. Plus if you learn a trick from a newer answer by someone else and blend this information into an older answer of yours, this may also lead to confusion.

@marmot Good point! However, shouldn't one prioritise helping the many, e.g. the ones who google the issue, than the one who asked? I mean if you update deprecated or obsolete stuff in your answer, then it might not work for the same version as the OP has (given that the OP has not updated the package), but would work for future googlers?

@AndreasStorvikStrauman keep a copy of the original answer. Below or above it write your updated answer. Both visually separated by a horizontal line and a big heading for each.

@Skillmon Noted and agreed!

@AndreasStorvikStrauman I think it is tricky and I certainly do not claim to have a perfect answer. However, in some ways the site here is a bit like academia, posts correspond to papers and votes to citations. In academia, you cannot update your paper later. However, I also understand that the internet works differently. So it's tricky. But I also think that @Skillmon's suggestion is good.

Hmm, have to do a panel meeting next month, get paid a bit: wondering whether I should spend it on TAOCP

@JosephWright That, or some other nice (set of) books sounds like a good thing.

@JosephWright I plan to get it as well one day :-)

@JosephWright maybe this question is stupid, but what is TAOCP?

@Skillmon The Art of Computer Programming by Donald E. Knuth

@JosephWright all volumes? Didn't know the abbreviation, but cited it for my bachelor's thesis.

@Skillmon The boxed set is about what I'll get for the panel meeting

@JosephWright If you were a mathematician, I would recommend you Mathematics made difficult.

@mickep Formally, I'm a chemist (uea.ac.uk/chemistry/people/profile/joseph-wright)

@JosephWright That is why I wrote "If you were...". I don't have any similar suggestion for chemists.

@mickep Oh, there are lots of things I could buy :)

@JosephWright I understand that, doing research on GOLD(!) :D

@mickep Mainly on iron: gold is more the work of a colleague

@barbarabeeton texdoc.net is running again, now with TeX Live 2018.

@StefanKottwitz Great stuff: many thanks for the hard work

@StefanKottwitz -- hey, super! thanks for the notice, and also all your good work.

@JosephWright Not so hard but as for most of us, it's about finding time (and motivation)

@StefanKottwitz Sure

@JosephWright I was in London 3 days this week btw. Spent most time in Chingford with a friend. All so British around (houses, pronunciation), nice!

@StefanKottwitz Cool

@StefanKottwitz Super!

@StefanKottwitz Will be good to catch up in person in Rio

@JosephWright @DavidCarlisle You two met at Windsor today, I guess. ;-)

@egreg Ho ho

@egreg I did go to a wedding-themed party: my sister booked for one in our village (at the local youth club)

@StefanKottwitz How many hits does texdoc.net get a day?

@JosephWright I may be in London from time to time too. I got friends there, with a contact-less credit card tube and overground rare easy-peasy and fast, flying from Hamburg is fast and cheap.

@JosephWright I don't know, as I don't track or count. Now I know at least 6 users. :-)

@marmot -- yeah, one credit card bureau did that with a check my husband wrote. (he picked up the "german 1" habit when he was a student in freiburg.) and it was really a big surprise to us when the check bounced. (but probably less of a surprise than if it had been cashed.)

@StefanKottwitz :)

@StefanKottwitz Sounds good

@StefanKottwitz I only really check for my blog as it affects the hosting cost ...

@JosephWright I notice usage when 400 Apache processes run on the web server (pure web services share a server, databases are on separate VMs) and memory tends to run out :-o I should add more RAM.

@StefanKottwitz :)

@JosephWright Check your hits on wp-login.php

that's a favorite URL ;-)

@egreg oddly, I wasn't invited

@DavidCarlisle You're in good company, as neither Mrs May was invited.

@egreg Who is Mrs May?

@FaheemMitha A lady who claims to be UK's Prime Minister. Maybe a hoax.

@egreg Oh.

Well, she should consider herself fortunate.

Btw, a pastor reading the wedding sermon from an iPad? Hilarious. @JosephWright @DavidCarlisle @egreg @PauloCereda

@yo' No time to learn it by heart? :-)

@egreg well, I think it's the future, in a sense, not to print the sermons but read them from a device.

@yo' funniest thing was watching the British establishment's reaction to a preacher who sounded like he actually believed what he was saying, and wasn't reading something written in the 1600s :-)

@DavidCarlisle well, this part is what made it to the news here :-)

@barbarabeeton Yes, a package that I sent to the US was returned for the same reason.
