@GonzaloMedina I believe cfr (Clae f. Rees) was never actice in chat. Because of this he (?) does unfortunately not get a notification. BTW also when one was not active for a longer time (amount unknown to me), he does not get notifications anymore (as it happened last time for you).
Hey @GonzaloMedina, the question you answered sparked a bit of research on my end, too, but I couldn't find any documentation for any TikZ 'graphs' or 'graphdrawing' library whatsoever—did you use texdoc or the wonderful powers of Google? Seems like a useful package to use considering my undergrad thesis :-)
@SeanAllred many tikz users have installed CVS 3.0.0 which has Graph Drawing Algorithms: features in changelog when compiled with lualatex engine. graphdrawing library does not work on 2.10 pgf version that is available on updated TeXLive.
Recently seen some answers by Mark Wibrow tex.stackexchange.com/a/159162/15717 that i could not compile and found out the latest library was in 3.0.0
I hope I am right since i have 2.10 on my machine.
Since the December 20, 2013, we have new major release of the wonderful TikZ/pgf package: version 3.0.0! 1
Unfortunately, I was not able to find a nice human readable list of changes, that goes to some depth and maybe even provides some examples. This page probably comes closest to it: 2

@DavidCarlisle I've been fiddling around with the '\Uchar-equivalent': working for the basics but fails when trying to force expansion. I think the EFO issue with \scantokens may be a killer here.
I was typing my homework and got this error:
! LaTeX Error: \mathfrak allowed only in math mode.
Recently I added some macros to my macro file that gives mathfrak text when used so, I figured I must have used that command without using math mode. I looked around and saw that since I last compil...
@JosephWright is there ever a time when you don't want \everyeof{\noexpand} ? Or instead of using the hook can't you add it to the definition of Uchar (so it doesn't need an assignment)
@DavidCarlisle Works directly in an \edef but not when I try to use it inside \tl_expandable_lowercase:n, which uses a \romannumeral-based forced expansion
@DavidCarlisle I'm working on the assumption that the idea of emulating \Uchar is to use charcodes to use a range-based approach to changing case, but that requires that the char can be forced to expand correctly.
Can you fix this? There are several horrors!

@jtbandes TikZ doesn't understand macros for paths. It works on branching upon the first character on the stream. So it has to see - to be able to switch to --,-| etc.
@jtbandes I would say, cook up your custom to path for this
@JosephWright something like that yes, but it seems that as long as you can get something that expands to the lowercase hex of a number in one expansion, that should be OK. Has to be such that romannumeral gives all the hex digits not just the first so you can stick ^^^^ in front and \noexpand after then use \scantokens
@JosephWright I was just looking at the etex manual now, is the extended ^^ notation documented? I thought it had to be 2 4 or 6 but I don't see it at all

@jtbandes The official version is 2.10 and it's on CTAN. But the authors of TikZ are keeping the source open and they release the development version which is known as the CVS version. And that's the prospective version number 3.00
I am trying to draw a simple path using TikZ, with a custom command to specify it. This works:
\newcommand{\latticepath}[1]{
\draw[thick] (0,0) node{} \foreach \x in {#1}{ -- \if u\x ++(0,1) \else ++(1,0) \fi node{}};
}
\begin{tikzpicture}[x=3mm,y=3mm]
\tikzset{every node/.style={circle,...
@egreg agreed, which brings me back to a discussion I had with @JosephWright earlier in the week, same might be said of accessing IEEE doubles, or regular expressions or ...
@DavidCarlisle Character tokens have a fixed location in TeX's memory, if I'm not mistaken. Adding a primitive that accesses that location shouldn't be so difficult.
@JosephWright ah OK as long as you have enough exp_after there. My version is working perfect;y when I run it in my head but xetex says I can't handle that very well; good luck.
\scantokens is more trouble than it's worth, while egreg is asking Khaled to implement Uchar he could ask him to remove this pointless end of file error at same time.
@JosephWright so you still need to be doing expansion when you get to the end of \scantokens so you can expand \noexpand to suppress the end of file error. If you are not doing expansion, \noexpand does nothing so you get an error. So it's all logical and all is well?
@JosephWright of course if someone were implementing Uchar, and expandable variant of \char then they might just implement an expandable \lowercase at same time.....
@JosephWright title case probably does live in the macro layer (or explicit end user markup, in the end) or you end up like bibtex which tries to do itautomatically and users spend all their time asking how to add markup to stop it
meanwhile is anyone else going to the cultural highlight of the year?
@PauloCereda Most of the chapters are stubs but the "Managing Data" chapter has the stuff about datatool and datatooltk. Some of the formatting needs adjusting. The draft's here: dickimaw-books.com/latex/admin/admin-report-draft.pdf
@DavidCarlisle I've thought of a way of avoiding Lua for case-changing in LuaTeX while still getting performance similar to XeTeX. This avoids using the unicode library, which doesn't seem to do quite what the Unicode docs specify!
@tohecz :-) I keep mistyping "duck". It's most unfortunate that i should be next to u on my keyboard. One day an embarrassing typo is going to slip into one of my books.
I'm a bit puzzled over displaymath. l2tabu advises against its use, but the reviewer of my LaTeX books thought me strange for advising the use of \[ and \] instead of \begin{displaymath} and \end{displaymath} since the displaymath environment is just defined to use \[ and \]. Why does l2tabu discourage it?
(I had a feeling it had something to do with amsmath but the amsmath user guide only makes a passing mention of displaymath that doesn't shed any light on the subject.)
@NicolaTalbot I believe it's a misunderstanding by l2tabu's authors (they say that amsmath would correctly redefine \[...\] but not displaymath. But of course amsmath doesn't have to since displaymath expands to \[ anyway.)
@NicolaTalbot In the German version of the companion you can find the following footnote related to displaymathinside the section about math-environemnts: Standard-LaTeX provides also the environment equation but doesn't provide a star version equation*. The later one is done by displaymath.
@MarcoDaniel I wonder how many people have been deprecating the use of displaymath with amsmath as a result of reading l2tabu. I think the authors need to update it.
Your tikzpicture is too big to fit in the page vertically. LaTeX tries its best to fit it in the first page and throws the error:
Overfull \vbox (147.53874pt too high) has occurred while \output is active
Being unsuccessful, it pushes the picture to the second page leaving first one empty.

Apparently (La)TeX pushes a figure that is too big for the first page to the second, and stops there. The logic of this escapes me.
If it is too big for the first page, it is too big for the second page. So why push it at all?
@FaheemMitha On the first page LaTeX tries, by the time the figure placement is attempted LaTeX cannot be sure that there is not some text on the page preventing it fitting. On the second page, it can: either it fits or the figure is simply too big to fit anywhere. So it gives up and dumps the figure.
frustration intensifies… I was installing the TikZ tds into my local texmf and more-or-less accidentally removed all of my local packages. I don't even remember if I have a backup, much less where I would have put them.
@SeanAllred <sad trombone sound here/> Sorry to hear. Things like this happen. I once wrote a wrong rule that removed my .tex file instead of the .aux file. Suddenly, the only thing left was the one file I wanna get rid of.
@SeanAllred I would play right now, but it's too hot in here. My system usually "fries", and add that some hot weather = I'll get the three rings of death soon. :)
I mean, in 2 weeks of a conference where they made like 1/3 of the program and the audience, they weren't able to explain anyone what is a co-algebra. And whatever the managed to show using co-algebras, I was able to show using standard stuff in half time and half text length
"Well, could you please explain us more precisely what is a coalgebra, and maybe give a well-defined example of it?" -- "Yes, of course. Do you see this diagram? That is co-algebra, if it commutes. Let's continue."
@egreg yes, but that seems to make CDs a goal, and not a tool for understanding.
For me, if someone writes in a paper: "... is redundant if and only if $F\Phi=\Phi G$, i.e., if the following diagram commutes: <CD here>," I'm happy since the diagram helped me to understand the statement. But that was never the case with co-stuff that those co-people tried to explain.
@PauloCereda I once accidentally deleted my PhD thesis. Luckily I was using an Acorn Archimedes so it was just a case of dumping all the free hard disk space into a file, stripping all the control codes, and there was my LaTeX source! (Along with a whole load of other deleted stuff. A 32Mb hard disk seemed awfully large at the time.)
@tohecz I stopped listening after I found out that covariant and contravariant vector difference is almost as simple as transposing a vector in my mechanics of continua lectures
@percusse covariant and contravariant has some meaning. You don't need such stuff for basic mechanics, but from some moment (STR at stuff), you quite can't be without that
btw, my Editor-in-charge won't like me: in this issue, like every second paper has only 5 lines of 120 on the last page ;)
@percusse ah the useless thing that you can take with you in metro :)
well, speaking of devices, @Paulo or others, any experience with digital voice recorders? I'm looking for higher quality for reasonable price, aiming at connecting it to my digital piano
@FaheemMitha geometry resets all layout dimensions, and does nothing more than that, so you can achieve the same result with or without it, it's just a bit painful sometimes :)
@FaheemMitha always specify \documentclass[a4paper]{whateverclassyouuse} since LaTeX knows to have double standards on default paper size. You save yourself a lot of troubles by doing this
@percusse Yes, it is, somehow. But honestly I tested couple studio headphones in the shop directly on the Yamaha pianos, and the Yamaha ones simply won :)
So when I went for something simple in-ear for travelling, I got Yamaha, too :)
This one is impressive, too, btw, but 90 vs 150? wtf?
the default at that level (in TeX for the standard classes) is always usletter. The driver probably defaults to a4 or use letter for positioning the typeset area on a physical page though. — David CarlisleNov 16 '12 at 13:03
I'm not sure what he means by that. There are two different places to choose paper size?
@DavidCarlisle The 'Uchar emulation' does have a use: means my code to turn the Unicode tables into something we can use works with both UTF-8 engines :-)
