@josephwright: Could the CW status of my answer to Documents with typical LaTeX errors be reverted?

7 hours later…

6:53 AM

@Werner Done

2 hours later…

8:36 AM

@TorbjørnT. Are you around for sometime?

@kan On and off, yeah.

@TorbjørnT. I have a tikz picture that I am trying to scale to fit in a page... Could you please take a look?

@kan Yeah, I remember you mentioned that yesterday. What was the link?

@TorbjørnT. Here it goes: pastebin.com/aYuHDe86. I would be very glad for any help in this regard. I have been going in circles for sometime now...

8:56 AM

@kan Well, I don't know why scale or x=.5cm,y=.5cm doesn't work, so I can only suggest some other ways of compacting things.

You could do every node/.style={font={\footnotesize},outer sep=0pt,inner sep=2pt} for the tikzpicture and column sep=-.5mm,row sep=-1mm for the matrix. Note that having a negative column sep does mess up those figures a little, but you can fix that by changing the end point of the dashed lines.

(Also, you're loading tikz twice, which is unnecessary, and amsart already loads amsmath ~~and amssymb~~ I think.)

@TorbjørnT. Hah, I see. But, I hope that will help settle matters...

@TorbjørnT. I agree, but I was in a hurry and just pulled together something for a MWE.

@TorbjørnT. Just that first modification was enough to contain it in a page!

Thank you very much

@kan Was it? It was a bit too large here, add \usepackage{showframe} to see the limits of the text area.

9:11 AM

@kan Ah, all's good then.

Strangely enough, clicking goes to a png! :-)

@TorbjørnT. Yeah! :-)

Now, the greedy me will insert a little more data into the picture...

Here is a lazy question. How do I configure texdoc to use evince? Currently it uses okular. I prefer evince.

This is on Debian, so it might be a Debian-specific question.

@FaheemMitha texdoc texdoc, see if section 1.4 is helpful.

@TorbjørnT. Thanks.

@TorbjørnT. That worked, thank you.

9:26 AM

@TorbjørnT. lynx lynx;) (I mean the animal, not the browser)

9:37 AM

@tohecz: woohoo Tom is back. :)

@PauloCereda but only for a while, I have to rush to work :)

@TorbjørnT. texception. :)

@tohecz ahhh. :(

9:53 AM

@FaheemMitha No, it's consistent with the behaviour of \@for which is a core LaTeX command.

\documentclass{article}


\begin{document}

\def\mylist{ foo,bar , wibble }

\makeatletter
\@for\this:=\mylist\do{``\this'' }
\makeatother

\end{document}

@NicolaTalbot I think the comparison was with other keyval implementations

!!/eightball Did you tell Nicola you are back, Psmith? :)

@PauloCereda Psmith, the TeX bot: The great 8-ball says: certainly not.

You are mean. :(

@PauloCereda he's right, he certainly had not told that her before ;)

@tohecz This bot seems consistent. :P

@JosephWright But it's the value that's a comma-separated list and that list isn't parsed with a keyval implementation.

@PauloCereda Yay!

!!/fortune

9:56 AM

@NicolaTalbot Psmith, the TeX bot: Here is your fortune: Confucius say: if you think we are going to sum up your whole life on this little bit of paper, you are crazy.

!!/cricket

Psmith, the TeX bot, in fixed font mode: Let's take a look at the last cricket results:

- Prime Minister's XI 92/10 * v England XI 264/8
- Habib Bank Limited v Zarai Taraqiati Bank Limited 240/4 *
- National Bank of Pakistan 38/2 * v Pakistan Television 125/10
- United Bank Limited 147/10 * v State Bank of Pakistan
- Melbourne Renegades 89/6 * v Sydney Thunder
- Ireland Women v South Africa Women

Our cricket expert David might explain these results later on.

!!/fortune

@PauloCereda Psmith, the TeX bot: Here is your fortune: Use emacs.

Boo!

@PauloCereda I was just about to suggest we celebrate Psmith's return. I'm not so sure now!

@NicolaTalbot He's too biased. :)

!!/eightball do you like emacs, Psmith?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: I'll answer after we have interviewed Paulo.

HEY WHO ADDED THAT TO MY BOT?!

5

!!/eightball can @PauloCereda watch the "National Bank of Pakistan" game on Brazillian TV?

9:59 AM

@DavidCarlisle Psmith, the TeX bot: The great 8-ball says: cannot predict now.

@DavidCarlisle ooh cricket money!

:)

!!/eightball will I ever understand cricket?

@PauloCereda He seems to be very consistent :p

@PauloCereda Psmith, the TeX bot: The great 8-ball says: I sense conflict.

@tohecz LOL

@PauloCereda extremly consistent!

!!/eightball Should @tohecz buy the knife?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: affirmative.

@PauloCereda :) now I really go

10:01 AM

@tohecz oh nooo

@NicolaTalbot OK. Well, regardless, I think it is rather unfortunate. I have heard keyval mentioned in this context. Is this something that could be used there?

@FaheemMitha One of the reasons we've written some standard 'comma list' code in expl3 is to have a consistent position for LaTeX3: spaces are removed :-)

IMO this violates the principle of least surprise. I've had other space-related problems with datatool which are probably related. Are you interested in test cases?

!!/eightball can we blame @Joseph for L3 stuff? :)

@PauloCereda Psmith, the TeX bot: The great 8-ball says: I sense conflict.

@JosephWright That sounds like a very good idea. Thanks. So, can anyone use this LaTeX 3 code now? Are there stability issues?

10:06 AM

34

Q: How "safe" is it to use LaTeX3 (l3packages, l3kernel)?

Are l3kernel and l3packages present in most of the LaTeX distributions? Are they "stable enough"? I am asking this because I am preparing a .tex document for a client. I have found convenient to use things like the xparse package or expl3 syntaxis. How likely is that the client will have problem...

incompatibility expl3 latex3 xparse

!!/eightball Is L3 safe?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: I say, old bean, do you really need to know?

@FaheemMitha Problem is of course 'work in progress': not everything is covered

@JosephWright Thanks.

@DavidCarlisle, @JosephWright: ^^

!!/eightball Do you like L3, Psmith?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: without a doubt.

@JosephWright Good answer, thanks.

10:08 AM

!!/eightball Have you ever fail the Turing test, Psmith?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: let's wait for David to finish xor first.

One of the things I've tried but so far failed to do is come up with a 'flexible' data structure for data tables. Bruno has some good ideas, but he's busy with other things.

!!/battle

@PauloCereda Psmith, the TeX bot: The current score is egreg 235 vs. 40 David. So far, egreg is winning.

Rep cap already?

@JosephWright The most difficult part is to define flexible. :P

@PauloCereda Bruno's idea is a generic 'object' data type to deal with everything beyond the basics, and then to implement different forms of object in different ways within that. Looks like a good plan but still needs to be done!

@PauloCereda No, that would be 245, but I'm confident.

@JosephWright Got it. Indeed it seems like a good plan and it certainly adds a good coverage. :) I might poke Bruno in the list on the subject. :)

@egreg :)

10:18 AM

@FaheemMitha At the moment I'm too busy to look at it, but I have a bug report form if you want to report any bugs.

@PauloCereda Now it's 245. But actually I was wrong, because I was given a 50 point bounty, so I need 50 more to be capped. I'm still confident. ;-)

@egreg :)

Argh, Till's questionable beamer decisions strike again

1

Q: \frame with options

If I want to use a "fragile" frame in a presentation I have to write \begin{frame}[fragile]{FRAME TITLE} \end{frame} Is there a way using the \frame{ \frametitle{FRAME TITLE} } syntax?

@JosephWright Wait for the new arara then. :P

@JosephWright Bad decision if ever there was one. Maybe in the first versions the \frame{...} was easier to manage and it was changed later, I don't know. The same applies for \adjustbox and \begin{adjustbox}, in my opinion.

10:48 AM

@egreg 0^0= ...?

Hm, that looks like an upside down bird. I mean: zero raised to the zeroth power is equal to?

!!/answer 0^0

Psmith, the TeX bot, in fixed font mode:

0^0
(indeterminate)

@PauloCereda Hehe!

@Jake <3

!!/answer the biggest prime number

Psmith, the TeX bot, in fixed font mode:

largest prime
There is no largest prime.
2^57885161-1
(as of February 2013)

Is this Wolfram Alpha in the background?

!!/answer is 1 prime?

Psmith, the TeX bot, in fixed font mode:

is 1 a prime number?
1 is not a prime number
2  |  3
1

!!/answer who are you?

Psmith, the TeX bot, in fixed font mode:

What is your name?
My name is Wolfram|Alpha.

@Jake: ^^ shhhh it's a secret. :)

10:51 AM

!!/answer plot x^0

Psmith, the TeX bot, in fixed font mode:

plot | x^0

What? No ASCII art?

@Jake I could not bind images yet. :(

@Jake Version 2.0 of the bot. :P

!!/answer when does Psmith 2.0 come out?

Oops, I crashed him

@Jake Psmith, the TeX bot: Oh no! We have an invalid command //answer when does Psmith 2.0 come out? here.

Psmith, the TeX bot, in fixed font mode:

come out  (English phrase)
1 | verb | appear or become visible; make a showing
2 | verb | be issued or published
3 | verb | come out of
4 | verb | result or end
5 | verb | come off
6 | verb | take a place in a competition; often followed by an ordinal
7 | verb | make oneself visible; take action
8 | verb | bulge outward
(11 meanings)

11:28 AM

@Jake 0^0=1, no discussion about it. ;-)

@Johannes_B Regarding golatex.de/kapitelueberschhrift-aendern-t12301,start,30.html I think I give up... :(

11:51 AM

@egreg Hehe, thank you

!!/answer What's 0^0?

Psmith, the TeX bot, in fixed font mode:

0^0
(indeterminate)

@PauloCereda Please, fix Psmith's bad ideas.

12:11 PM

@egreg There are quite a lot of things in beamer that I'd do differently!

@egreg It's Wolfram's, not Psmith's. :)

@NicolaTalbot OK, I'll consider doing that. Thanks.

@PauloCereda Then Mr Wolfram should be fixed.

!!/eightball should we believe Wolfram or @egreg?

@DavidCarlisle !! :)

@DavidCarlisle Psmith, the TeX bot: The great 8-ball says: I'm too busy thinking about ducks to answer right now.

@DavidCarlisle Psmith, the TeX bot: The great 8-ball says: outlook not so good.

!!/choose egreg, Wolfram

@PauloCereda Psmith, the TeX bot: The great oracle says: egreg

@DavidCarlisle: ^^

12:37 PM

@PauloCereda The Great Oracle spoke. ;-)

12:49 PM

@egreg :)

@egreg: I won Fifa 14 for my Xbox. I tried to select Palmeiras as my default team, but it was unavailable. Guess my second choice. :)

@PauloCereda never trust a bot

!!/eightball Should we trust you, Psmith? :)

@PauloCereda Psmith, the TeX bot: The great 8-ball says: no way.

Then I should not trust the bot, but if the bot is telling a lie, I should trust the bot, then the bot is telling the truth.

aaaaaaaaaaaaaaaaaaaaaaaaah /head explodes

@PauloCereda Good choice, of course.

@egreg :)

!!/eightball Can I have ice cream?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: absolutely not.

Oh.

1:15 PM

@egreg: does Juve have a Brazil-like uniform?! It just appeared as 2nd or 3rd uniform.

@PauloCereda Sometimes they use a yellow uniform.

1:34 PM

@egreg Oh that one.

1:51 PM

!!/choose poke Alan, do nothing

@PauloCereda Psmith, the TeX bot: The great oracle says: do nothing

oh. :(

2:16 PM

@cgnieder I guess we all said what we had to say and everything is fine now.

hi does anybody know how to align tikzpictures within a tabular?

would the package adjustbox be of use?

!!/translate from de to en Meine bestellten Artikel in so wenige Einzellieferungen wie möglich zusammenfassen.

@tohecz Psmith, the TeX bot: Incorrect syntax, try from LANG to LANG TEXT instead.

@tohecz Psmith, the TeX bot: Only 20 in stock (on the road)

@tohecz Psmith, the TeX bot: My ordered articles summarize in as few individual supplies as possible.

2:32 PM

@PauloCereda Psmith seems to speak German very well :)

@tohecz ooh! :)

@PauloCereda :)

!!/eightball Can we have ice cream now?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: yes.

wooho

3:04 PM

Hi. Is it possible to configure things so that references are shown enclosed by a square bracket? By default they are just a number.

i suppose i could redefine ref as the original ref surrounded by square brackets or similar. would that work?

@FaheemMitha Yes, it should. Be cautious when using hyperref.

@egreg Why is hyperref a problem?

Should I use a different name for this custom ref?

3:22 PM

@FaheemMitha mainly make sure you let hyperref redefine everything before you save the old version of \ref to add your [] otherwise you will re-instate the original definition (which will fail as hyperref redefines \label)

@FaheemMitha You must use \LetLtxMacro\Originalref\ref (letltxmacro package) for saving the old meaning, when hyperref is used. Then you have to take care that the \ref command has a *-form, with hyperref.

@FaheemMitha Or do as David says.

@egreg No idea what this means.

@DavidCarlisle So, do the redefinition after the usepackage line for hyperref?

hi--any tikz folks around?

I'm actually not using hyperref here, but good to know regardless.

@JG We're all tikz folks now.

@FaheemMitha yes or simpler if you don't mind a new name \newcommand\myref[1]{[\ref{#1}]} can go anywhere

3:25 PM

@FaheemMitha cool!

@DavidCarlisle Is using a different name reasonable here?

@FaheemMitha especially @egreg and myself (we have badges to prove it)

I just wanted to ask about the code in the last solution posted in: tex.stackexchange.com/questions/147580/…

experts != folks

In particular, as I've commented, how could the darkness or color of the circles be adjusted?

3:26 PM

@FaheemMitha it's your document: if it is reasonable to you it is reasonable, otherwise not. The AMS \eqref command is basically just \ref with () added for example.

@DavidCarlisle Ok.

3:38 PM

@JG \draw [black!20]: The colour used is black!20 which is 20% black (and the rest white, I guess). Using a higher value than 20 will make the lines darker.

@TorbjørnT. ok thanks for try for example \draw [black!40] Thanks!

4:05 PM

Hi -- anybody aorund?

I'm trying to make a poste

However, I do not know how to show what the current output of the code looks like.

I've seen other folks to this I believe. I'm guessing that would be helpful when the code is long?

4:25 PM

@JG take a screenshot, crop as necessary and post an image using the editor (or ctrl-G (or drag and drop in some browsers)

I'm guessing this produces a recursive loop. I get a TeX capacity exceeded

\renewcommand\ref[1]{[\ref{#1}]}

but I'm not sure of the correct way to handle it.

This guy has got to be kidding... tex.stackexchange.com/questions/153819/…

@FaheemMitha Yes it is, indeed. One way is to make a copy of the previous ref (call it e.g.\oldref) and then use that in the new definition.

@AlanMunn Yes, I did that, and it works.

Is the green square a cousin of @egreg?

4:33 PM

But presumably redefining the macro is also an option.

user image

@FaheemMitha But I would be wary of redefining such a basic and widely used macro.

@DavidCarlisle I don't know him, but it could be.

@DavidCarlisle There's a crazy triangle there. :)

@FaheemMitha \newcommand\myref[1]{[\ref{#1}]} or \let\oldref\ref\renewcommand\ref[1]{[\oldref{#1}]} or what egreg said above with letltxmacro

4:36 PM

@TorbjørnT. thank you for your posting!

!!/texdef -t latex ref

Psmith, the TeX bot, in fixed font mode: Here's the output from texdef:

\ref:
macro:#1->\expandafter \@setref \csname r@#1\endcsname \@firstoftwo {#1}

@FaheemMitha Yes, that's what I meant: for example \let\oldfoo\foo \renewcommand\foo[1]{\oldfoo{#1}}

@PauloCereda before hyperref redefines everything

!!/texdef -t latex -p hyperref ref

@PauloCereda Psmith, the TeX bot: Oh no! We have an invalid command /\texdef -t latex -p hyperref ref here.

@FaheemMitha the \newcommand\myref[1]{[\ref{#1}]} form is far less stressful:-)

@PauloCereda You should have read the user manual first.

4:39 PM

Psmith, the TeX bot, in fixed font mode: Here's the output from texdef:

\ref:
macro:->\protect \ref


\ref :
\long macro:->\@ifstar \@refstar \T@ref

@DavidCarlisle LOL

@TorbjørnT. thank you for your posting to my question. may i ask you one follow up?

sorry for the double post just now.

@JG Sure.

i am wondering if i could center align the second row a little bit so that the graph "D" is not directly vertical below the graph "A"? i recognize that was not part of my intiial question becaues it is not my primary concern

!!/choose read manual,ask David

@AlanMunn Psmith, the TeX bot: The great oracle says: read manual

!!/eightball Is David a reliable source?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: yes, definitely.

4:43 PM

!!/eightball Is Psmith a reliable source?

@AlanMunn Psmith, the TeX bot: The great 8-ball says: only when pink elephants learn to fly.

I hate this bot.

@AlanMunn Sure, but I would like to know how to do it. I agree that redefining it may not be a great idea.

@DavidCarlisle Ok, I guess \let\oldref\ref\renewcommand\ref[1]{[\oldref{#1}]} would work. Time to look up \let. :-)

Oh, I see. That is exactly what it is typically used for.

@Jubobs He wants something quick and dirty?

@PauloCereda well, do you know any pink elephant that cannot fly? :D

@egreg I could use either \let or \LetLtxMacro?

@tohecz Certainly every pink elephant that I've met could.

@FaheemMitha \let will fail with hyperref; that's what @egreg 's last comment said.

4:54 PM

@FaheemMitha If you do it after loading hyperref you need \LetLtxMacro, but then something like \renewcommand{\ref}[1]{\oldref{#1}} will work only partially: no *-form would be allowed.

@egreg I see.

@AlanMunn Oh, it does?

Maybe I'll just redefine it. Sounds safer.

@Jubobs commented.

@egreg "no *-form" of what?

@FaheemMitha Of \ref, of course

@tohecz thank you for modifying the code more substantially!

@tohecz this is a minor point. but initially the axes had arrows on both sides, and now they seem to have only an arrow on one end. that is, the y-axis has the arrow only pointing up whereas the x-axis has one only pointing to the right

5:06 PM

@egreg Oh, that's a hyperref thing.

@JG which code? Are you sure you want to speak to me? :)

@tohecz sorry!

@TorbjørnT. thank you for modifying the code in your post! this is a minor point. but initially the axes had arrows on both sides, and now they seem to have only an arrow on one end. that is, the y-axis has the arrow only pointing up whereas the x-axis has one only pointing to the right

@JG no worries

every time I make an Amazon order, I end up ordering much more than what I originally came for

@tohecz That's why you should use @PauloCereda's credit card.

@DavidCarlisle well, he hasn't given me the number yet. promises, promises ...

btw, it's funny how much is German amazon cheaper than the French one for some things.

5:14 PM

!!/eightball Does @tohecz deserve the credit card?

@PauloCereda Psmith, the TeX bot: The great 8-ball says: totally.

:)

@tohecz I occasionally get stuff on amazon.fr and now they keep sending me email offering me stuff, but I'm not sure what:-)

@DavidCarlisle Wine and cheese!

@tohecz Thanks :)

5:44 PM

@PauloCereda Do you know of a way to get the IP address of a Mac printer?

@AlanMunn Hm good question. Let me check some sources. :)

Hi chat. Been a while.

@JosephWright: ^^ :)

@CharlesStewart Hello, Charles! Long time no see!

Charles Stewart

I've been checking into the site, just not chat so much

Tempted here by a link I saw - I guess several folk will be interested

Nice to have non-mathematician journal editors make a strong case for Latex over Word.

Hi all! I'm learning about creating documentclasses and packages, I've created a documentclass for writing articles for a journal in my university. I'm no expert, I relied on the IEEEtran' class and the article' class. Is there a chance to give a look and give me your recommendations?

6:38 PM

@OSjerick Hello! Does your class have \RequirePackage{tabu} somewhere? :)

If anyone is encouraged, here are the documents. Unfortunately the manual is in Spanish :( https://drive.google.com/file/d/0BxFKCIz7VScIRTF6TFVUZXJRbGM/edit?usp=sharing
https://drive.google.com/file/d/0BxFKCIz7VScIckZQZzV6allzVjQ/edit?usp=sharing

@OSjerick It's inspired by IEEEtran indeed. :) Nice template. :)

@PauloCereda this tabu package, no :)

@OSjerick Great. :) Then you are safe. :)

@JosephWright: that bird is so joyful, please choose it as the L3 mascot. :)

6:57 PM

@PauloCereda However, there are times where I have to force line breaks (with \\) to see the beforeskip of a section title. I did it before sections 3.2 and 3.3 of the manual. I do not know what happens, if it has to do with using listings or another thing.

@egreg I don't consider \phi : \alphabetA \to \alphabetB^* more readable than \phi : \A \to \B. Or even a better example: \LL=\LL_0 \LL_1 \LL_2 \dotsm \subset \Z^\omega vs \langL = \langL_0 \langL_1 \langL_2 \dotsm \subset \integerSet^\inftyrepeat

@tohecz Did I say "long names"?

@egreg \phi : \alpA \to \alpB^*

7:22 PM

@tohecz Going mountain climbing, are we?

7:34 PM

@AlanMunn yeah, and arbitrary many times, because of the Kleene star ;)

@egreg: apparently Palmeiras is in the game. :) Since we were in serie B last year, and Palmeiras is amongst the most influential teams in Brazil, Fifa decided not to include it in the Liga do Brasil category (some teams aren't there due to license) and put Palmeiras into the Rest of the world category. :)

Gotta go, dinner, then back home, and straight to bed :)

8:41 PM

@tohecz Perhaps.

1 hour later…

10:07 PM

@PauloCereda I thought we had the humming bird thing

@JosephWright Hummingbird FTW. :)

@PauloCereda latex-project.org/latex3.html

@JosephWright <3

@Joseph: 30GB done? :)

11:04 PM

How about the No Pants Subway Ride in Brazil, @paulo?

@CodeMocker My recommendation is “remember to put on your underwear on the ‘No Pants Subway Ride’ day”.

11:29 PM

@CodeMocker Nope. :)

@egreg I see.

@PauloCereda :-)

@JosephWright: you got mail. :)
