@egreg Yes, but … is this for things like \g@addto@macro\tmp{\def\foo#1{#1}} that would fail otherwise?

egreg

@Qrrbrbirlbel That's an application

Paulo Cereda

@DavidCarlisle Oh my! More money to spend? :)

@egreg: can I ask a quick L3 question? :)

Oh nevermind, got it! I'm getting the grip finally! :)

Qrrbrbirlbel

00:41

@PeterGrill Do you mind adding solutions that use path picture or append after command?

Peter Grill

:8840212: I don't really do that often so would have to hack at it to get it to work. You can add it though.

cmhughes

01:02

hello to all :)

Karl's students

@cmhughes Hello mathematician!

Qrrbrbirlbel

@PeterGrill Hm, okay. :)

cmhughes

@Karl'sstudents Hi Karl- your comment was truly inspired- it seems some other folks agree- I have 6 stars for it so far :)

Peter Grill

@Qrrbrbirlbel You didn't like my optimization since #1=n and #2=k you can just use n and k. :-)

Karl's students

@cmhughes Thank you. It is just a joke actually.

cmhughes

01:08

@Karl'sstudents I know :) twas a good response to the unnecessary downvote though :)

Karl's students

@cmhughes :-)

cmhughes

@Karl'sstudents will we ever learn your true identity? Are you secretly Bruce Wayne?

Karl's students

@cmhughes :-)

Paulo Cereda

01:29

@cmhughes The cool thing about being Batman is, of course, being Batman. :)

cmhughes

@PauloCereda good point :) if @Karl'sstudents is Batman I would love to audition for the part of Robin. Or maybe Alfred

Paulo Cereda

@cmhughes nananananananana Batman!

cmhughes

@PauloCereda Right, boy wonder!

@Karl'sstudents is one of those people you? has your identity been revealed?!

Karl's students

01:34

@cmhughes No. I have an ugly face.

cmhughes

@Karl'sstudents lol

Paulo Cereda

@cmhughes Holy \expandafter, Batman!

cmhughes

@PauloCereda Let's use our 'bat-energy-saving' run!

@PauloCereda any plans for the weekend? :)

Karl's students

I know who has not upvoted it yet. :-)

cmhughes

@Karl'sstudents how do you know? :)

Karl's students

01:47

@cmhughes Hmm... it is a secret. :-)

cmhughes

@Karl'sstudents dang, you're the king of secrets :0

Karl's students

@cmhughes You can share your secret and I will keep it strictly. :-)

cmhughes

@Karl'sstudents I don't have any :)

Karl's students

@cmhughes Really?

How much is your salary a month? :-)

cmhughes

@Karl'sstudents millions and millions!

Karl's students

01:55

@cmhughes Oh my ghost.

cmhughes

@Karl'sstudents it's not that useful- I get paid in goats

Karl's students

@cmhughes Oh it is your secret then.

cmhughes

@Karl'sstudents not any more...

Karl's students

@cmhughes Paid in goats is an english idiom?

cmhughes

@Karl'sstudents no, just my poor sense of humour :)

Karl's students

01:59

@cmhughes Oh I see. I start laughing now... :-)

cmhughes

@Karl'sstudents lol :) I'm just stepping away for a bit of food- will be back later :)

Karl's students

@cmhughes Are you married?

Paulo Cereda

@cmhughes Some games, soccer, a date, more games. :)

Karl's students

I am also stepping away for a bit of baby food (seriously baby food), I will be back soon.

Q: Arcing arrow and keeping proper arrow head orientation

I have \draw[draw=black!80,solid, -triangle 90,fill=black!80] (2.6, 4) -- (3.3, 4); I'd like the endpoints to be where they are, but I need it to arc. How do I do this? Edit: I'm looking for something like this: \draw [->] (0,0) arc (180:30:10pt); Something like the curved arrow, except...

cmhughes

@Karl'sstudents yes indeedyo :)

@PauloCereda cool, that sounds like fun!

Qrrbrbirlbel

@PeterGrill I have added a path picture solution, a little more different than your solution, but the positioning is similar (relative to the north east corner).

Peter Grill

@Qrrbrbirlbel Nice.

cmhughes

02:46

quick sanity check: am I missing any headings: \part, \chapter, \section, \subsection, \subsubsection. \paragraph, \subparagraph

Qrrbrbirlbel

@PeterGrill Uh, I just see that there's already a star shape. Oh well …

Peter Grill

@Qrrbrbirlbel there is??

@Karl'sstudents I don't even know anything about you, silly.

Karl's students

@JasperLoy :-)

user19161

@Karl'sstudents Will you tell me your secrets in email?

Karl's students

@JasperLoy It is hard, very hard, almost impossible. :D

user19161

04:10

@Karl'sstudents Then I am afraid we cannot make any progress in our friendship... I know nothing about you, other than the fact that you use pstricks, lol.

Karl's students

@JasperLoy I have an ugly face. That is all. :D

If i wish to understand what the animate package does or want to do something like this myself, is there a gentle introduction or tutorial? I know there's a 700+ page reference from adobe, but I don't even know JavaScript yet ;-)

So I'd like something on the "for dummies" level...

Frank Mittelbach

09:17

@PauloCereda thanks :-) and thanks @MarcoDaniel ... Never saw your best wishes as "@Frank" doesn't seem to do the trick from some strange reason :-) perhaps because I wasn't online for a while ... isn't 3*17 so much better than 2*5*5?

- fix for showgrid=true
- fix for \uput@vii#1#2
- fix for introduced bug for pst@dotFill
- fix for introduced bug with missing
definition for \@width
- make package pgffor available

Karl's students

@MarcoDaniel OK. Thanks for informing this.

But the announcement has not been displayed tug.org/PSTricks/main.cgi.

Karl's students

10:40

The following weird feature should be fixed:

in PSTricks and PGF/TikZ, Mar 23 at 19:58, by Karl's students

\documentclass[preview,border=12pt,varwidth]{standalone}
\usepackage{pstricks}
\parindent=0pt
\def\getrow#1\relax{\def\Row{#1}}
\newcount\buffer

\begin{document}
\psforeach{\row}%
	{%
		{{1,2,3}},%<----- when will this unusual feature be fixed?
		{4,5,6},%
		{7,8,9}%
	}%
	{%
		\expandafter\getrow\row\relax
		\buffer=\psLoopIndex\relax
		\endgraf\psforeach{\col}{\Row}{(\the\buffer,\the\psLoopIndex) = \col,}%
		\psLoopIndex=\buffer\relax
	}%
\end{document}

Marco Daniel

@Karl'sstudents but here: groups.google.com/forum/#!topic/comp.text.tex/rYQtfFM9_LM

Karl's students

@MarcoDaniel The following bug in uput has not been fixed yet:

\documentclass[pstricks,border=12pt]{standalone}
\SpecialCoor
\begin{document}
\begin{pspicture}[showgrid](3,3)
	\uput{!2 sqrt}[45](0,0){\psdots(0,0)}
\end{pspicture}
\end{document}

labelsep wrongly interprets the RPN expression of the square root of 2.

Marco Daniel

10:57

@Karl'sstudents I don't know whether labelsep is allows in this notation or not. I think the expression is used at TeX level.

Karl's students

@MarcoDaniel Maybe, but only labelsep behaves differently:

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{pst-node}
\psset{saveNodeCoors}
\usepackage{fp}
\FPeval\Distance{round(2^0.5:3)}

\begin{document}
\begin{pspicture}[showgrid](3,3)

	\uput{\Distance}[!N-A.y N-A.x atan](0,0){\psdots(0,0)}

@egreg I read this but I can't understand the result ;-) Maybe the op will answer my comment.

Paulo Cereda

11:21

Out of curiosity, is there a way to append a text to every bibitem?

Marco Daniel

@PauloCereda Always the same text?

Paulo Cereda

@MarcoDaniel Yep, just a marker for me to delimit the search when analyzing the log file. :)

I can post a question.

Marco Daniel

@PauloCereda Something with typeout or wlog?

Paulo Cereda

@MarcoDaniel Yes, one of these would be great! I just don't know where to patch and insert the hook.

Marco Daniel

@PauloCereda Try

\documentclass{article}

\usepackage{biblatex}

\addbibresource{biblatex-examples.bib}

\begin{document}

\cite{companion}
\cite{ctan}


\renewbibmacro*{finentry}{\finentry\wlog{here is the end}}
\printbibliography

\end{document}

Paulo Cereda

11:33

@MarcoDaniel Oh, it sounds promising! :)

Marco Daniel

@PauloCereda lol

Paulo Cereda

@MarcoDaniel Danke. :)

Marco Daniel

@Karl'sstudents curious.

Paulo Cereda

@MarcoDaniel: It works perfectly. :) I'll ask a question for a more specific usage. :)

Marco Daniel

@PauloCereda I will wait

Paulo Cereda

11:40

@MarcoDaniel I don't want to bother you. <3

It will be a follow-up to this question of mine: tex.stackexchange.com/questions/90031

Marco Daniel

@PauloCereda I didn't see this question.

Paulo Cereda

I was planning of adding a "mark" every time a bibitem is displayed. But we have two issues: the references are saved inside a box, so \wlog is expanded right away, and if I add a random text, say, "#END#", it's typeset in the box content, but also in the document output. :)

Am I crazy, aren't I? :D

Marco Daniel

11:54

@PauloCereda Did you try this example with arara? The following compilation fails

% arara: pdflatex
% arara: biber
% arara: pdflatex
% arara: pdflatex

\documentclass{article}

\usepackage{biblatex}
\addbibresource{biblatex-examples.bib}

\usepackage{letltxmacro}
\LetLtxMacro\biblatexprintbibliography\printbibliography
\newsavebox\bibbox

\sbox\z@{\vbox{\printbibliography[#1]}}
\batchmode
\wlog{BEGIN BIBLIOGRAPHY}

Paulo Cereda

12:06

@MarcoDaniel That's odd, it works with programs called separately.

Marco Daniel

@PauloCereda I know. Really odd

Paulo Cereda

@MarcoDaniel Not arara's fault, pdflatex is returning 1.

I think every time you have a log interaction, you make pdflatex scream 1.

Joseph Wright

@PauloCereda Yup

Paulo Cereda

@MarcoDaniel: now it makes sense why dandelion was complaining about pdflatex's return. :)

Marco Daniel

@PauloCereda :-)

Paulo Cereda

12:12

@JosephWright ooh secret powers. :)

Do you guys have any special folder for .tex tests? I have one under ~/Documents/Sandbox :)

Marco Daniel

@PauloCereda Yes .trash ;-)

Joseph Wright

@PauloCereda I just have test.tex on my Desktop

Paulo Cereda

@MarcoDaniel You are evil. <3

@JosephWright Oh my! Create some folder structure, please. :)

Marco Daniel

@JosephWright Really? I have a folder test with test.tex -- I don't like help files on my desktop.

Joseph Wright

@MarcoDaniel Only thing I have there :-)

I delete the aux files as soon as I've done testing

Paulo Cereda

12:16

@JosephWright This is ~~Sparta~~ LaTeX3.

@JosephWright: speaking of L3, I'm having so much fun with interface3.pdf. Now I'm able to write cool macros. :)

paulo@alexandria Sandbox$ find . -type f | wc -l

Only a few files. :)

egreg

12:56

Here's what I found today in the App Store

Should I install them?

Paulo Cereda

@egreg Yes. Yes. YES! :)

egreg

@PauloCereda And use them with XeLaTeX, of course.

Paulo Cereda

@egreg Yay! :) And don't forget to use to use \setlength{\parskip}{1.5\baselineskip}, \setlength{\parindent}{0pt} and \OnehalfSpacing. :)

The crowning touch. :)

@egreg: beware, App Store is dangerous. :)

egreg

@PauloCereda I can also use the \XeTeXinterchartoks feature for automatically changing fonts between letters.

Paulo Cereda

@egreg woohoo, even better! :)

Joseph Wright

13:14

@brunolefloch I think I can guess at least some of the motivation behind tex.stackexchange.com/questions/107208/… :-)

13:35

@JosephWright Another one of Bruno's dirty tricks?

Joseph Wright

Of general interest: physicsworld.com/cws/article/indepth/2013/jan/10/… (registration required but free to read)

Pointed out to me by a UK-TUG member

@egreg github.com/latex3/svn-mirror/issues/141

Marco Daniel

@JosephWright Are the effort worth?

Silex

@egreg It looks "Kinda Creepy" ;)

Joseph Wright

13:52

@MarcoDaniel If you've followed some of the complaints about TeX and the fact that it's not a single program, then perhaps not. However, it's in an IoP journal, so probably is being worth aware of. I'm surprised by some of it, as I'd expect more technical accuracy from the author (who is involved in one of the TeX-on-pad products)

For example, it says KerTeX is a 'fork' of TeX and compares it to pdfTeX: not true

Also there is a part that says 'LaTeX bloat' (lots of files) means that typesetting takes a long time compared to a web browser rendering a page, which again is simply not accurate

Marco Daniel

@JosephWright Ok. Too much errors ;-)

Joseph Wright

14:07

@MarcoDaniel Well, I'd say more that it needed a careful review, as would happen for an academic article :-) As I said, worth being aware of because a lot of non-experts probably see things this way.

There's a general tendency to see (La)TeX as the same as InDesign or XPress (or even Word), whereas a fairer comparison is GNU

Paulo Cereda

@JosephWright Currently, I'm having more fun with LaTeX then with InDesign or Scribus. :)

Joseph Wright

@PauloCereda One issue that the article doesn't cover is that while 'end users' see themselves as the big target, LaTeX is a publishing tool. Looked at from that POV, it does not matter if you can't run it on a tablet, as no-one is doing that for their day-to-day typesetting in a publishing house.

Paulo Cereda

@JosephWright Agreed. :) /note to self: make TeX run on my smartphone

egreg

@PauloCereda You can't interrupt a \showbox.

Paulo Cereda

@egreg I was afraid of that. :(

@egreg: I think the only way is to rely on finentry then.

egreg

14:18

@PauloCereda The string .....\T1/cmr/m/n/10 [ denotes the beginning of an entry.

Paulo Cereda

@egreg I was trying to avoid looking for [, since I might have different enclosing symbols, like (1) or 1.. :(

Marco Daniel

@PauloCereda: Where do you use the box content later?

Paulo Cereda

@MarcoDaniel In the log.

Karl's students

Interruption: Why isn't it compilable?

\documentclass{beamer}
\begin{document}
\frame
Hello Universe
\endframe
\end{document}

Marco Daniel

@PauloCereda Speaking simple: \begingroup\vbox\egroup \renewcommand<all> \printbibliography\egroup\endgroup should work too.

egreg

14:32

@Karl'sstudents Because \frame should be used with a brace after it. In any case this is similar to \align and \endalign that can't work.

Karl's students

and also \document ....\enddocument does not work.

egreg

@Karl'sstudents That's for sure. Check how \document is defined

!!/texdef -t latex document

Joseph Wright

@Karl'sstudents beamer does a lot of pre-processing to do its work, so it needs either an explicit \begin{frame} ... \end{frame} pair or \frame{<content>}

Marco Daniel

Norbert wrote the truth: tex.stackexchange.com/a/107162/5239

On Windows this is unfortunately not so trivial, as the uninstaller and the registry etc etc is linked to release years, it is simply a pain on Windows, but that is a special case.

Joseph Wright

The fact that LaTeX2e allows \foo ... \endfoo for things intended as environments is unfortunate: the LaTeX3 plan is to store these explicitly separately from \foo as a command

Karl's students

14:34

@JosephWright and @egreg: OK. Thank you for responding.

egreg

@Karl'sstudents Since Psmith is on holiday, here is the beginning of \document:

\document:
macro:->\endgroup \ifx \@unusedoptionlist \@empty \else

Paulo Cereda

@egreg Hold on! :P

Joseph Wright

@MarcoDaniel Well yes, but good practice on Windows is not to name installation locations after versions (or years), so you could argue that this is starting from the wrong place ('we will name our installation locations after versions, ...')

@PauloCereda: Is permission from SE needed to run a bot in your browser session?

Paulo Cereda

@Karl'sstudents As long as you don't spam too much, it's OK. But you always need to keep an eye on the bot.

Karl's students

14:50

So everyone can run their own different purpose bots without permission from SE administrators?

It is interesting!

Paulo Cereda

@egreg: Do you think I can use the number of dots in the beginning of the entry as a reference, ..... ?

@Karl'sstudents Apparently you didn't read my meta-thread on Psmith. :)

Karl's students

@PauloCereda I am reading now...

Paulo Cereda

@Karl'sstudents The last part is about SO et al. :)

Karl's students

@PauloCereda !!/draw[red] (1,1) circle (1);

Oh... nothing happens.

Paulo Cereda

@Karl'sstudents Now you are asking too much for Psmith. :)

He's not a PSTricks wizard like you. :)

Karl's students

14:56

You should add drawing capabilities to psmith. :-)

Paulo Cereda

@Karl'sstudents It's a good idea. :)

egreg

@PauloCereda Not necessarily; the dots represent the level of boxing. The only way I see is to use the font name as a marker.

But even if one uses \let for defining an equivalent, TeX always uses the name it has in memory. :(

Paulo Cereda

@egreg Ah I see. :( I better provide the item style them, so I can look for [1] or (1) or...

@egreg: I'm tempted to delete my question. Would you like to add some insight or better send it to the TeX purgatory? :)

egreg

@PauloCereda If you're using T1 encoding, you can add \textcompwordmark as the first character in the item label. You'll get ^^W in the line.

\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
\showboxdepth=\maxdimen
\showboxbreadth=\maxdimen
\sbox0{[1]}
\showbox0
\sbox0{\textcompwordmark[1]}
\showbox0

And here's the response

> \box0=
\hbox(7.49817+2.49939)x10.55298
.\T1/cmr/m/n/10 [
.\T1/cmr/m/n/10 1
.\T1/cmr/m/n/10 ]

! OK.
l.8 \showbox0

?
> \box0=
\hbox(7.49817+2.49939)x10.55298
.\T1/cmr/m/n/10 ^^W
.\T1/cmr/m/n/10 [
.\T1/cmr/m/n/10 1

@Jayesh: don't mind Psmith, sometimes he's very biased. :)

Jayesh Badwaik

@PauloCereda Hahaha. :-) Apparently, PSmith thinks emacs is free of incompleteness. :P

egreg

@JayeshBadwaik Incompleteness theorem: Formal theories in which recursive functions can be represented are incomplete, except for Emacs.

Paulo Cereda

15:25

@egreg: thanks for the answer, I'll accept ASAP, since I'm out of votes. I don't want to accept an answer without upvoting it. :)

@MarcoDaniel: egreg found an awesome solution for my question. I was looking at your trad-biblatex files, but I could not find the proper info. Now I need to insert \textcompwordmark before typesetting [1]. I suppose I have to add a hook in \AtEveryBibitem?

Marco Daniel

@PauloCereda correct.

It's a great solution. I didn't know the command \textcompwordmark

Paulo Cereda

@MarcoDaniel Neither did I. :)

Yay @Frank is here! Hopefully with cake. :)

egreg

@MarcoDaniel It's an invisible character that can be used for breaking ligatures, but the main usage is for marking components of words, so that hyphenation can be performed only on the various parts, not taking into account bogus break points due to the word connections.

Kannappan Sampath

@egreg: nice game. :)

Nicola Talbot

@PauloCereda Hello! :-) I've just got back from visiting my family for the week.

Oh, guess what :-)

Paulo Cereda

@NicolaTalbot Welcome back! :)

@NicolaTalbot no idea. :)

Nicola Talbot

@PauloCereda I've got a tablet :-) Linux powered. Ice-cream sandwich OS.

Paulo Cereda

@NicolaTalbot Yay, how nice!

Nicola Talbot

@PauloCereda I'm still trying to work out how to use it!

@PauloCereda Did you have a good Easter?

Paulo Cereda

17:58

@NicolaTalbot I did, it was great, thanks. :) And yours?

Nicola Talbot

@PauloCereda Great :-) My niece liked the duck audio extract, and my nephew's already requested a copy of the duck book, even though it's not ready yet :-)

Paulo Cereda

@NicolaTalbot woohoo! :) I'm very excited to see the final release. :)

Nicola Talbot

@PauloCereda Hopefully it won't be long now :-) I need to find somewhere that can scan in all the background images, then I'll have some fun with gimp.

Paulo Cereda

@NicolaTalbot :)

egreg

@PauloCereda Great goalie.

Nicola Talbot

18:11

@PauloCereda Yay, I can chat via my tablet! Very slowly :-)

Paulo Cereda

@egreg Indeed. :) I got scared when Pescara scored.

Hm I'm close: I need to exploit biblabel.

Nicola Talbot

@PauloCereda What are you trying to do?

Paulo Cereda

@NicolaTalbot I'm trying to prepend \textcompwordmark to every biblabel [1] with biblatex. :)

Nicola Talbot

@PauloCereda Oh, that's beyond my biblatex knowledge.

Paulo Cereda

@NicolaTalbot I kinda know what to do, not how. :)

Nicola Talbot

18:24

@PauloCereda That's always a good start :-)

Hmm, the touch screen is going to take a bit of getting used to.

I need to sort out a week's backlog of things to do! Bye for now.

Hey guys, I have a quick question. I am using \include to put chapters into my book but of course, there is an empty page before and after the \include which is not seen in books. How can I change that? Should I just use \input?

@gekkostate This question and its answers may be helpful:

Q: When should I use \input vs. \include?

There are two different commands to incorporate another file into the source of some document, \input and \include. When should I use one or the other? What are the differences between them? Are there more things like them to be aware of?

include input

gekkostate

@cgnieder yes, I looked into that. But I was still unsure. For some reason, the empty pages seems to be omitted in createspace. So right now, I'm dandy.

cgnieder

18:59

@gekkostate what do you mean by »the empty pages seems to be omitted in createspace«?

gekkostate

@cgnieder When I was reviewing on createspace through they interior design feature, there were no empty pages after the end of each chapter and before the beginning of each chapter

cgnieder

@gekkostate Well, since \include always calls \clearpage you probably want \input. But that won't suffice if you're using \chapter as it too calls \clearpage (in oneside documents) or \cleardoublepage (in twoside documents).

gekkostate

19:14

@cgnieder Then would what be the best option?

cgnieder

@gekkostate have a look at

Q: Start new chapter on same page

I am using report document class. When I create a new chapter, it starts it on a new blank page in which only the chapter name appears. I want to be able to start new chapters on the same page as the old chapter ends. Is there any way to do it?

sectioning page-breaking chapters

gekkostate

@cgnieder okay, I'll look into that. Thanks a bunch!

AlanH

19:40

hi all

Paulo Cereda

@AlanH Aloha! :)

AlanH

I'm trying to figure out how to position some tikz figures (from other files) on to one page. Does the paper (in landscape) work as a coordinate system, like graph paper?

I'm very new to tikz, and I've yet to find such a post (still searching though)

gekkostate

Is anyone familiar with the memoir errors \spinemargin and \footskip?

cgnieder

@AlanH Hi :) Maybe you could show a little example of what you're trying? I don't really understand what you mean by »Does the paper (in landscape) work as a coordinate system«... are you asking if there is a way for absolute positioning objects on a page?

Qrrbrbirlbel

@AlanH How to you include the external TikZ figures? With \includegraphics?

AlanH

19:51

@Qrrbrbirlbel That's what I plan to do, but I don't know how it works. It just get an image in a random spot on the paper.

Qrrbrbirlbel

@AlanH Consider the included TikZ picture as one letter/character you let TeX typeset. The TikZ picture (or any external stuff for that matter) is put in one box and typeset by TeX. Unless you put it into a special environment or macro (say a float like figure) nothing special happens with the picture.

AlanH

@cgnieder Yeah, as if I grab the figure with my own hands and say "I want the figure in this exact location". So does (0,0) start at the very bottom left corner of the paper?

Qrrbrbirlbel

@AlanH The coordinate system of TikZ is local.

\tikz \draw (0,0) -- (1,1); and \tikz \draw (123,653) -- (124,654); will be the exact same picture with dimensions of 1cm by 1cm.

@AlanH There is one question/answer on the site where the coordinate system of TikZ is places on the bottom left corner of the page. (There are special nodes in TikZ for that; or you can remove any margins.)

AlanH

@Qrrbrbirlbel But where are they located on the paper? What would I have to do to say I want figure 1 to be in the top left corner of the paper. Figure 2 to be in the center. Figure 3 to be in the bottom right corner

@Qrrbrbirlbel May you provide the link, please? I've dug all morning and the closest thing I've found is tex.stackexchange.com/questions/9281/… and the sankey diagram

egreg

@PauloCereda I don't think this is the best way to do it, but this works for the problem of adding \textcompwordmark:

\makeatletter
\patchcmd{\blx@env@bibliography}{\hss}{\hss\textcompwordmark}{}{}
\makeatother

cgnieder

19:58

@AlanH IIRC the eso-pic package provides means for absolute positioning of objects. There's also textpos. I've never used any of them so I can't say how good or bad they work...

AlanH

@Qrrbrbirlbel I just found this! tex.stackexchange.com/questions/1159/… Is this what you are referring to?

egreg

@PauloCereda Here's a part of the log file

....\hbox(7.49817+2.49939)x10.55298
.....\glue 0.0 plus 1.0fil minus 1.0fil
.....\T1/cmr/m/n/10 ^^W
.....\T1/cmr/m/n/10 [
.....\T1/cmr/m/n/10 1
.....\T1/cmr/m/n/10 ]

Qrrbrbirlbel

@AlanH I'll try to find it. Though, it is an example where the TikZ picture is produces live and not from an external file. If you have external files, there may be other or better ways.

Q: Aligning image and text in new command in TikZ

As a Teaching Assistant for a class, I am trying to draw a seating chart for the professor. The seating chart will have a photo of each student, the student's name, and where the student is sitting in the lecture room. Using labels and anchors in TikZ, I am able to manually create a label for ea...

tikz-pgf macros

@AlanH Read the Notes section in my answer. But this is for in-document TikZ pictures. For external file, you can either use also TikZ to place them or search the main site for absolute positioning and external files or something like that. And what @cgnieder said.

AlanH

@AlanH Well, I thought the recommended route for really complicated diagrams was to compose each chunk individually and then put it together with external files? I read somewhere on the site that this was better because it's not as messy.

Paulo Cereda

@egreg Thank you very much! I was trying to look for any "native" trick via \AtEveryBibitem, but I can't find any hints in the documentation. :(

@egreg: in other news, what happened to Vučinić? :P

Why is pstricks (among others) skipped when updating my TeX Live 2012 as shown in the following screenshot?

AlanH

@Qrrbrbirlbel Well, I thought the recommended route for really complicated diagrams was to compose each chunk individually and then put it together with external files? I read somewhere on the site that this was better because it's not as messy.

egreg

@PauloCereda As usual, he played with slippers instead of soccer shoes for the first half.

Qrrbrbirlbel

@AlanH True, though I can't say much without grasping an idea of what you are trying to achieve. Are the contents of each picture local to the picture itself? Then it is ok to externalize them. Is this a one-page document (like a poster) or do you want to place these pictures on every page of a long document or ...?

Paulo Cereda

@egreg True. :)

Qrrbrbirlbel

@AlanH I have never placed external graphics in TeX before (and at this point the external PDF containing the TikZ picture isn't different from any other PDF page or picture you can include).

AlanH

20:14

@AlanH Are you saying I should redo all of my figures so that I get them in one file? :(

@Qrrbrbirlbel Are you saying I should redo all of my figures so that I get them in one file? :(

Qrrbrbirlbel

@AlanH No, I'm saying that I don't know exactly how to position external graphics absolutely on the page. Have you taken a look at the textpos package?

AlanH

20:27

@Qrrbrbirlbel Hm. I'll look into that. How do i upload pictures here? I drew out what I wanted.

Qrrbrbirlbel

@AlanH Hm, it looks like you can actual use the answer I've linked to, and use \node[inner sep=0pt, outer sep=0pt, anchor=north west] at (current page.north west) {\includegraphics{figure1.pdf}};; so the whole picture acts as one node

(Don't forget overlay and remember picture options.)

AlanH

@Qrrbrbirlbel Are you referring to pg. 199 of the pgf manual? mirror.jmu.edu/pub/CTAN/graphics/pgf/base/doc/generic/pgf/…

Qrrbrbirlbel

@AlanH And 200. There is even an example with the current page node.

AlanH

@Qrrbrbirlbel Thanks a lot for your help!

Hey guys, I have a quick question. How come createspace is complaining about the chapter names being in too low dpi? I am using memoir and bianchi style

Paulo Cereda

@egreg Wow! A big goal for today's session.

cgnieder

@PauloCereda lol (but sadly that is how it often is)

Paulo Cereda

@cgnieder :)

an event

even though i won't be of any help

@egreg i guess so many new questions comes to math.se everyday

Paulo Cereda

20:51

@DominicMichaelis You can help! Upvote, look for questions... :)

Wait for my epic announcement.

:)

Dominic Michaelis

ok i can upvote your sophisticated answers for sure :)

egreg

@DominicMichaelis You can try looking old questions that have no example months after it has been requested. These are candidates for being closed as too localized, as it's usually impossible to give sensible answers. Just copy the link, paste it here and add a line explaining why it should be closed. Or maybe try adding an answer!

Paulo Cereda

@percusse: sir, we need another beer keg.

is this one ?
