@Qrrbrbirlbel At TeX-SX the party never ends so you can never be too late to join it.
8:11 AM
@someonr the log file should give you a hint where it is if you put \loggingoutput in your preamble the box contents will be shown in full so you'll be ale to tell which box it is
8:53 AM
@egreg: Fantastic answer: meta.tex.stackexchange.com/a/2832/3094 I wish I could upvote it 10 times. :)

I need to post more ducks here. :)
@PauloCereda SAS (symbol abuse syndrome): it's a typical syndrome of the young mathematician that can be cured by exposing the patient to well written papers and books (not Bourbaki's, of course) where symbols are properly used. If not cured in time it can become symbolitis which causes impossibility to be understood when delivering lectures; for papers and books there's usually some editor that can remedy the cyphered prose.
@egreg Agreed. :) Sometimes, we are tempted to use more symbols instead of trying to explain the same idea with plain text. Instead of making our ideas clear, we hide them inside a sea of symbols.
9:38 AM
@GonzaloMedina, @PeterGrill, @percuse and other tikzmark enthusiasts:
in From Answers to Packages, 50 secs ago, by Andrew Stacey
Initial version of tikzmark package uploaded to launchpad. I thought of having the tikzmark package itself just with the basics but also providing a tikzmarkextras with some of the more useful/popular/remarkable answers/uses in it. So ... any suggestions for what those should be?
@AndrewStacey Yay! :)
(Just realised that I left percuse out of the "people that have abused tikzmark" list. Not sure if this is a good or bad thing.)
10:01 AM
ahora arara habla español, viva!
10:23 AM
@JosephWright (and @DavidCarlisle might have a useful opinion). Should tex.stackexchange.com/q/78887/86 be closed rather as a "duplicate" than "too localised"? (Technically, all I'm really asking is "Should someone add the link more prominently in the question?" than actually bothering to change the close reason.)
@PauloCereda Is that done using TikZ?
@AndrewStacey i voted for close as duplicate, as I said in the comments it's a FFFAQ so I don't see how TL applies
@JasperLoy Sadly no. :(
@DavidCarlisle It's a majority decision so it might be that the TL votes were applied before you commented.
@JasperLoy @PauloCereda uses picture mode not this newfangled tikz stuff
@AndrewStacey yes that's why the system closed it, but why did the people vote that way:-)
10:32 AM
@DavidCarlisle Because the early voters didn't realise that it was a FFFAQ (and one we'd seen before). Without knowing that it does look a bit "too localised".
11:12 AM
@JasperLoy @PauloCereda Do you want it to be?
@AndrewStacey It's OK I'm abusing it behind close doors and washing my hands before and afterwards.
@percusse <3
@percusse: possible exploit found. :)
Q: Migrated question from meta to main allows me to upvote same comment twice

Paulo CeredaFriends, I noticed something "interesting" today. The question How to include a long underscore before the `\question` command? was originally posted in our meta site. Andrew wrote a comment in the question, and I upvoted his comment (I also voted the question for closing/migration). Now the q...

@PauloCereda Aha 42 votes a day.... Sweet :P
We could vote twice. rubbing hands, evil laugh
... on comments.
@percusse I've no response to that.
@percusse perhaps @AndrewStacey could start a new list of people who do not wish to receive the black spot^H^H^H^H^H^H^H^H^H^H tikzmark
11:27 AM
Well, I was going to say something about permanent tikzmarkers, but decided against it.
@AndrewStacey Recap after use.... :P
@AndrewStacey Today, comments. Tomorrow, questions. :)
@DavidCarlisle We are yet to see your TikZmark answer with longtable that reaches out to previous pages!
say, an arrow starting from page 2 and pointing to something on page 1
@percusse perhaps it's posted to the wall of the smallest room in the house
@DavidCarlisle Oh, with this precious knowledge I'll be rich !!
12:12 PM
@egreg really a matter of habits. In articles I read and write, there's "We say that x is positive if x>0" as a defintion.
@tohecz That's why Halmos introduced a new word. The "if" here is an abuse of language, since usually "if" is used in conditional statement. A definition is not a statement in the same sense that we use in a theorem: "If a function is continuous on the real line and assumes positive and negative values, then it assumes the value 0".
@egreg I don't argue with you. But for me, to some sense, correct is what most people do.
12:34 PM
Is it only me, or everytime you see LaTex written somewhere, you want to punch horses?
@PauloCereda Doesn't that count as an acceptable edit?
@AndrewStacey I think so. :) But it's in another community. :(
@PauloCereda This one, perchance:
A: Typography area for StackExchange

e100I completely disagree that "typographic communities are typically separate [from Graphic Design]", "Typography is quite distinct from "Graphic Design" (raxacoricofallapatorius, in a comment on another answer). I've no idea where you get this idea from -- typography is absolutely fundamental to g...

@AndrewStacey Exactly. :)
@PauloCereda I did like the containing sentence: "It would arguably be correct to say that some forms of typesetting (e.g. LaTex [sic and sick]) do not cross over much with graphic design."
12:40 PM
@AndrewStacey :)
What rejoinders shall we send? Ducks, pullquotes?
Both! To the fire guns! :D
I summon admiral @percusse!
@PauloCereda Yay! it seems that someone's really read the announcement ;)
@tohecz I did! :)
And upvoted it. :)
@PauloCereda ok :)
@AndrewStacey I added a comment there
12:45 PM
@tohecz ooh that's gonna hurt! <3
I notice that this "model question" doesn't have a "model answer" as yet: area51.stackexchange.com/proposals/40151/typography/40161#40161 Will I inspire a backlash if I answer "None"?
@PauloCereda but let's face it, someone who is not able to spell such name correctly clearly doesn't care about typography and hence his opinion on the topic is moreorless invalid.
@PauloCereda At your service commander general
@percusse <3
@PauloCereda Ore miner under attack...
1:03 PM
@percusse any problem? :)
@tohecz I always wanted to be the narrator in Command & Conquer
such a nice job...
@percusse: we could develop some sort of "LaTeX hero" game. :)
@percusse OMG!
@PauloCereda That would need a lot of expansion packs, keh keh. I'm so funny.
@percusse More DLC! :)
1:33 PM
@percusse: any plans for the new Xbox? :)
@PauloCereda No not really. I have my own box. Something looks like this :)
@percusse Oh no! Matlab code! :)
1:49 PM
@egreg What new word are you referring to?
2:16 PM
I'm getting an idea of how @DavidCarlisle feels. I just answered a question without testing the code. Sort of scary, sort of exciting. A bit like jumping out of an aeroplane without looking to see if it was in the air or not.
@AndrewStacey :)
Quick question: Can I insert the value of a variable like \textwidth in my texdocument to see how large it is?
2:34 PM
@halirutan 'ello! :)
@halirutan \the\textwidth
@halirutan There have been some questions about \the, e.g. tex.stackexchange.com/questions/23291/… and tex.stackexchange.com/questions/38674/the-the-command
@halirutan Torbjørn's answer is correct. :) You can also use a package named printlen and then \printlength{\textwidth}. :)
@JasperLoy "iff"
@egreg In Portuguese we have "sse" (se e somente se). :P
For the same purpose. :)
@PauloCereda Some perverse Italian uses the same.
2:39 PM
@egreg Oh no! :)
I'm not a fan of abbreviations. :)
How about proposing Ducks.SE?
Hi. I remember seeing a question about including a bibliography entry in the body of the document, for example, to include a list of publications in of a given author. Does someone has an idea of which question I am talking about?
Is there a source for newer builds of tikz then texample.net/tikz/builds?
@TorbjørnT. Thanks, I searched tex.SE, but I was not sure for what I should search.. "print variables"..
@TorbjørnT. In the meantime I found my error. \textwidth was correct but there was an additional \columnsep I missed in my calculation ;-)
For the pie charts
user image
And of course I should have known this: one always uses \the\section or similar.
3:00 PM
@percusse LOL
@percusse I don't understand, what is funny?
@halirutan No: in LaTeX \the\section throws an error. Rather \thesection (notice the difference).
Hello everyone
@Alenanno 'ello!
@egreg hmm, ups.. yes I was referring to \thesection
3:10 PM
3:21 PM
Hi @Alenanno, I started writing a response to your pie chart question, and figured I went to the trouble and so might as well share it, dl.dropbox.com/u/3385251/pies_tex.html
@AndyW Hello Andry, sorry. I saw that it was considered as OT and I'd rather delete it altogether.
Thanks for sharing the answer though.
No problem
@halirutan maybe you want to see the tabularx package? ctan.org/pkg/tabularx
@Alenanno I hope you didn't take my comment the wrong way. It's an interesting question, but do you see why this might be considered off-topic for this site? Maybe you could edit it to make the link to TeX clearer?
@Jake I wasn't offended or anything... I thought that it didn't reach my hoped response from the community so I deleted it... I might try to fix it later :) If I find a way.
3:33 PM
@Alenanno That would be great!
@AndrewStacey Interesting comparison. Reminds me of wondermark.com/881 a bit.
3:52 PM
@Jake Reminds me of the question as to how many London buses make up an Olympic swimming pool.
4:16 PM
@AndrewStacey Only one I think:
4:42 PM
@tohecz If you chop its arms off I reckon you could get another one.
@AndrewStacey: can I ask you an iPad-related question? :)
@PauloCereda Sure.
@AndrewStacey I'm planning to get an iPad by Christmas. I've seen that Apple released a "mini" version; to be honest, I still would prefer the "big" iPad instead. Do you think the current iPad size is ok to be used, say, while travelling in the bus or train, or perhaps the smaller one might have an advantage?
4:59 PM
@PauloCereda I haven't tried anything in between an iPad and a smartphone, but when using the smartphone then I felt that I wouldn't like to have anything smaller than an iPad in place of my iPad. Namely, the way that I use my iPad (as a slimline laptop) would be really constrained by a smaller screen since the touch interface would be that much more unreliable. (ctd)
As it is, I find that I can type a TeX document on it, write 20,000 lines of lua code to make a klein bottle (okay, it wasn't all to make that bottle), and not get annoyed.
Also, I think that I'd find it hard to write (as in use a stylus) on anything smaller: there's always a loss of screen real estate as your arm covers up a fair bit of the screen when you write and so the smaller the screen, the more awkward it becomes.
On the other hand, an iPad is about as big and heavy as it could be for reading. Even as it is, it's awkward to hold in one hand and read (as opposed to, say, a paperback book). In that regard it is more like a hardback book: you figure out someway to hold it where you are resting it a bit more (could be holding it from hand-to-elbow if that makes any sense).
So while I expect that there are occasions where the smaller size of the mini makes it easier than the fullsized version, the rest of the time you're going to wish you'd gotten the fullsized one. So I recommend that.
@AndrewStacey Of course, Apple wants you to get both of them ;)
@AndrewStacey: Thank you very much for the insight. :) The smaller iPad looks cool in the keynote video, but I don't believe a small device would work for me. Thanks for opening my mind. :)
@tohecz :)
@tohecz Of course. But you know what they say about having too many apples.
I know Apple products might be considered overpriced, but everything in Brazil is overpriced, so I prefer to stick with something that works. :P
@PauloCereda I guess the key question is that in my blog post: will it be a slimline laptop or an oversized phone?
5:06 PM
@AndrewStacey The first one. :)
Speaking of apples...
When do you think Apple will be considering India as a market?
@PauloCereda Then certainly my recommendation is the larger one. I cannot imagine how awful my typing would be on any smaller screen.
@orange I'm more bemused by someone with the username orange asking about apples ...
@orange In Brazil, I think Apple doesn't have a strong market. :(
@PauloCereda if you asked me, I iDontLike
@tohecz I can understand. :)
5:09 PM
Well I love apple products but love orange as a fruit.
@PauloCereda but in India smartPhone users are increasing day by day(A huge market) but I am not finding any reason why Apple is ignoring India.There is not a single Apple store over here.
@orange Really? Well, to be honest, I think Brazil has one. For the whole country. :)
@PauloCereda amazon FTW
@tohecz Brazilian Amazon or a Brazilian Amazon branch? :P
@PauloCereda does it really matter? They're optimised to selling, so as long as you pay, they sell. Locations are irrelevant.
@tohecz Sadly it matters for us. :( Import taxes.
Immoral and inhuman import taxes, by the way. :(
5:21 PM
@PauloCereda I understand. But that won't change the price. Either you buy e.g. in US and you pay the taxes, or Amazon sells in Brazil and the price will be higher by the taxes.
@tohecz Yes. :) The problem is that the Brazilian government has a few extra taxes applied to goods. Sometimes, we have to pay 50% - 200% (!) more for some products.
@PauloCereda well, for a notebook it's easy: make a trip to US
(I know it's not so easy)
(and it obviously works for a notebook and/or a camera, but not for anything larger)
5:38 PM
@tohecz The travel expenses are high too. :)
@PauloCereda Hmmmmmm, then I think you should move out of the town and farm ducks
@tohecz I live in the state of São Paulo, the economical heart of Brazil. :P
I wish I had a duck. :(
@PauloCereda I've sent you some:
@tohecz Yay, a duck! :)
@ガベージコレクタ LOL
5:47 PM
@PauloCereda: Someone should make it with TikZ.
@ガベージコレクタ :)
@ガベージコレクタ \node[shape = extendcurvetoxxx] ...
@PauloCereda I'm trying to better emulate the-program-I-won't-say-the-name-of
@egreg ooh it's a very nice approximation!
Part of Friday's talk; just set some parameters along with \usepackage{wordlike}
5:56 PM
@egreg ah! :)
This is how it appears with my friend's Ivan suftesi class
@egreg Cool!
6:11 PM
@egreg: Any ComicSans version? :)

Proposed Q&A site for anyone lacking social skills wanting to find out how to react in a particular situation; about social conventions, customs, social interactions, social situations and behaviours.

Currently in commitment.

"How can I behave when someone shows me a document written in Word?"
Don't tell me it's not a valid question. :P
6:35 PM
Hi. Does anyone have a working TL 2010 (preferably on a Mac, although that's probably not crucial) and could test compile a small document for me?
Hi @NicolaTalbot I'm glad to see you hanging out here now too. I'm a big fan of csvtools and you've always been super helpful on c.t.t.
@AlanMunn Thanks. (Did you know csvtools has been replaced by datatool?)
@NicolaTalbot Yes, that was a total mixup on my part.
@AlanMunn That's okay. I noticed there was a question here about csvtools, but when I tried to test it out I realised I no longer had a copy!
@NicolaTalbot Oops. Luckily I think it's still archived on CTAN, no?
@AlanMunn Yes, it's still hanging around in the obsolete tree.
6:49 PM
@AlanMunn I have TL2011 in my old Mac.
@NicolaTalbot: Maybe that's why we use Fedora: we like hats. :)
@PauloCereda Definitely. And, after all, the fedora is superior to all other hats!
@NicolaTalbot Indeed! :) Every time I wear a Fedora, somehow the Indiana Jones soundtrack starts playing in my head. :P
@PauloCereda :-)
(Sound of whip cracking.)
@PauloCereda I don't think that will help. Someone I was helping on a mailing list couldn't compile a simple tikz document when the array package was loaded. I'm a bit unclear on whether he was reporting the issue correctly, and he was using TL 2010, so I thought maybe there was maybe some incompatibility. But I don't think array interacts with much. He seems content not to use it, so I think I won't pursue the issue further. Thanks, though. BTW I will get back to your e-mail. :)
@NicolaTalbot :)
6:55 PM
@PauloCereda: Did you install vim via homebrew?
@AlanMunn Ah I hope the issue will be sorted out. :) I have TL2007 (or 2009) which came with The LaTeX Companion, but I think it's too old. :P (Don't worry with the e-mail, I think we both are busy :P )
@MarcoDaniel code.google.com/p/macvim Best. Editor. Ever.
I need an outdated TL version, so I could install it in my Wii which has an obsolete glibc. :)
@PauloCereda And let the wars begin. :)
@PauloCereda Oh, fedora and vim - you have chosen the path to wisdom, my friend.
@PauloCereda Thanks.
@NicolaTalbot Don't let him fool you. @egreg and I just convinced him recently to buy a Mac and he's very happy with it.
7:00 PM
Jun 12 at 20:36, by David Carlisle
@PauloCereda yes, but they use vim though so I don't speak to them
@AlanMunn LOL
@NicolaTalbot Indeed. :) @Alan is right, I'm now a happy Mac user, altough I have Fedora in two machines (including one of my devs), one with Windows and one with Slackware. :)
@AndrewStacey That's awesome Andrew. Am so glad that I am not on the list of people that have abused \tikzmark. :-)
As long as uname -a | grep Ubuntu doesn't return anything, we'll be OK. :)
@AlanMunn I have TL2010 on Mac. What do you need tested?
As it happens it's also a tikzmark document:

@ガベージコレクタ My math prof University would actually draw a semi circle around the max values, color it in, and then draw a thick tick mark at the peak to point it out. It was never as blatant as your images, but we all understood what he was getting at. He was actually very good at explaining things, just hope some of the females in the class were not too uncomfortable.
@AlanMunn Trying now... Just hope this does not get on the \tikzmark abuse list thought...
7:08 PM
@PauloCereda Always found a Mac desktop too fancy for my liking. Too many graphical thingies whizzing around the place!
@PeterGrill Thanks. Well it's in the interest of converting someone from PSTricks, so any abuse is allowed. :) And let the wars begin...
@AlanMunn Works great with TL2010, TL2011, TL2012. Did the OP know that multiple runs were required? Of course the lines drawn are in black, which I would never do. :-)
@NicolaTalbot I had the same thought, until I found Mountain Lion + Magic Mouse + Magic Trackpad + gestures. I feel like that Tony Stark + Jarvis. :)
@PeterGrill That's what I thought. It seemed really unlikely that it wouldn't run and the error that the person was reporting contained a line of code not actually in the document! But he seems to be content with the solution so I'm not inclined to press him more. Thanks for testing.
Seems strange... Perhaps some .aux file corruption from an earlier run?
7:15 PM
@PauloCereda Mountain Lion + Magic Mouse + Magic Trackpad? Sounds like something from a children's story! Ooh, that's got me thinking. Once upon a time...
@NicolaTalbot :) Do you know my cat's name? :)
@PauloCereda No, do tell :-)
@PeterGrill That would be my bet. The person is a complete beginner, so troubleshooting is a bit tedious.
@NicolaTalbot I have two, actually. :) They are named Ciça and Fubá (fubá is cornmeal in Portuguese). :)
@PauloCereda These are lolling cats. (Paulo, you may need to look that one up, it's a real word...) Not to be confused with lolcats.
7:21 PM
@PauloCereda I like the way they've both chosen the same pose!
@AlanMunn OMG. You are right! thefreedictionary.com/lolling
@NicolaTalbot In the same table, different days. :)
@PauloCereda They look dog-tired :-)
@NicolaTalbot They are lazy. :)
Good GMT19:28, everybody!
@tohecz Hello!
7:29 PM
@tohecz Meow. I mean, quack. :)
Can you tell me why people keep doing this?
\caption{Scheme of a generic event based control strategy. The dashed arrows indicate the possibility of event-triggered data transmission.}
@tohecz Ask Nelly!
@NicolaTalbot who?
@tohecz From what I can remember, the PracTeX Journal has an "Ask Nelly" section that derived it's name from the habit of asking the person in the next office how to do something. (Although I might have misremembered that.) The same old code gets propagated.
@NicolaTalbot but that code is double stupid.
7:33 PM
@tohecz In that case, I think Nelly is not the best person, tell them to go to Helen Fry. :P
@tohecz You wouldn't believe the kind of code I've seen!
@NicolaTalbot I'm a graphical editor of a journal, trust me, I would ;)
@tohecz Ah, a fellow battle-weary comrade.
@NicolaTalbot what do you do?
@tohecz In addition to my publishing company, I'm also the production editor for the Challenges in Machine Learning series (published by Microtome). And occasionally I teach LaTeX. And I also sometimes do some machine learning research. I used to do some research in food poisoning, which made a great meal-time topic ;-) And I write as well.
7:40 PM
@NicolaTalbot Cool, machine learning! I had some fun working with question answering. :)
@PauloCereda :-)
@Nicola question from English typography: the article "a" at the end of line -- is it frowned upon?
Yay Patrick @topskip Gundlach is here! :D
@tohecz I know "I" is, so I would've thought "a" is as well. I'd have to look it up.
@PauloCereda ... now finally some time to work :-) (its almost 10 pm)
7:45 PM
@topskip :)
.. I have not been into office for the whole month now. tomorrow is my first day. I was traveling around almost all the time
... only read the above link if you like comic sans ...
We all love comic sans, don't we?
@topskip OMG
@tohecz Just checked with the Oxford style: non-breaking word space should be used "if possible, after the indefinite article 'a' and personal pronoun 'I'."
Thanks a lot. Now, we have to tell TeX what means "if possible"
@tohecz ? Inserting ~ should do the trick!?
7:50 PM
@topskip it means: "Even if it's not possible"
I think that "If possible" is \penalty9999\
Hello\perhapsbreak world.
@tohecz you can always play with this (you use LuaTeX, don't you)?
A: one-letter word at the end of line

topskipThis is a LuaLaTeX solution. It is a function that gets called just before TeX breaks the text into lines. It inserts ties ~ (only the penalty of 10000, the glue is already there) after the single letter word. Words will still hyphenate (see example below) - as far as I can see (after the w). [E...

@topskip no, I don't of course
@tohecz "of course" :))
yo peeps
7:53 PM
@Pureferret peepshow?
I was googling 'christmas list latex' and it brought me to this chat where someone talked about asking that question
was it ever asked?
@Pureferret what? :)
(we should answer with xii.tex from @DavidCarlisle)
@Pureferret cool :)
7:55 PM
So I did my research but I found nothing
can I go ask the question now?
I couldn't find the question they referenced
8:07 PM
@topskip you could give that as the answer to every question
- I have a TikZ question...
- xii.tex . Next.
John Denver! Run!
Damn you Fozzy! :P
8:39 PM
@PauloCereda Oh no, Fozzy had to be the best character. After all, he always wore a hat :-)
@NicolaTalbot Indeed! :) And he was voiced by the great Frank Oz. :)
He forgot the lyrics. :P
@PauloCereda He was just covering for John Denver :-P
@NicolaTalbot ooh! :)
Speaking of which, John Denver is the next on my playlist. :P
@PauloCereda If you want to open the floor for requests, I'll go with "The sun has got his hat on".
(I'm in need of a cheerful song. I've just discovered that my hedgehog proof has an error, and I'm mortified.)
@NicolaTalbot Oh. My. God. Epic song! :)
@NicolaTalbot Oh. :(
@NicolaTalbot: every time I need to cheer up, this song helps: youtube.com/watch?v=mML2fPec7xU :)
8:54 PM
@PauloCereda Excellent! Well, that's chased the blues away. My sunny disposition has returned, and I'm now up to the task of fixing my hedgehog :-)
@NicolaTalbot Proofs are overrated anyway :P
@percusse \begin{overratedproof}
@Nicola: Two other songs that I like: youtube.com/watch?v=RBr3FXnbdYY (Tico-tico no fubá, conducted by Daniel Barenboim) and youtube.com/watch?v=VCg-VT4RlBE (Apanhei-te cavaquinho, by a chorinho quartet). Brazilian classics. :)
9:09 PM
@NicolaTalbot There was a famous quote along the lines of one should derive rather than prove but my ignorance took over now so nevermind.
@Werner thanks for uploading the image!
@GonzaloMedina No problem.
@percusse I shall derive my hedgehog ;-)
@PauloCereda They're great. Have you seen youtube.com/watch?v=R6IfpZUqERk The cellist is amazing! I never thought it was possible to dance while playing the cello!
chatbot response
@NicolaTalbot Wow, fantastic! :)
@percusse I share the first comment of the video. :)

@egreg You should expand on that comment :p
@egreg OMG amazing!
Gambler's Fallacy maybe?
9:51 PM
Hello friends.
@kan 'ello!
@StephanLehmke: Dortmund won today! :)
@N3buchadnezzar hi! :)
@percusse Are two solutions sufficient?
@egreg An elegant l3 solution. :)
10:22 PM
@PeterGrill Oh but you are.
Yay! My Raspberry Pi can do morse code! Next stop, linebreaking algorithm.
Bye... time to go to bed.... :-)
10:40 PM
@PauloCereda can you please connect to gmail for a minute?
@kan Good night! :)
@GonzaloMedina Sure! :)
10:50 PM
@egreg Usually we suffer from the nonexpansion inside \foreach but now I see that it's expanded properly. Is it special to \csname...\endcsname that it is fully expanded?
@percusse Yes, everything in \csname...\endcsname is fully expanded.
@egreg Ah, I was indeed overly cautious then.
@percusse The problem with \foreach is that each cycle is made inside a group. It's not about expansion.
@egreg But if you remember many other questions, we had to make sure that the variable is expanded properly. Grouping was also a problem as in \i becoming iota etc. That part I think I understood.
@percusse That's another problem, but it's about the timing of expansion.
10:56 PM
Q: Shrink tikz trees

TassHow can I reduce the overall size of trees drawn by tikz-qtree? I've got a huge parse tree that doesn't even try to fit on one page. I'd like to either resize the full tree or tweak the placing algorithm to make the tree more dense.

Is "don't water them" a valid answer? :)
You see, if you say \foreach\i in{a,b,c}{\def\macro{\i}} (apart from being silly), the code will perform \def\macro{\i} because there's no chance for \i to expand.
@PauloCereda Hahahaha, definitely!!!
@egreg Yep, that's my misuse of terminology. I meant that one.
I was trying to avoid that without checking it first.
@percusse However, what I don't like in those solutions is that they do \def\yy{_\uppercase{yy}} which is not the best.
(I'm not mentioning \ensuremath, of course)
@egreg Heheh, I also don't like the pragmatic mass definitions but .. yeah let the things happen :)
@percusse Yes, you end up not knowing precisely what's defined and what isn't.
