@yo' ;)

Nobody having problems with CTAN? I get the same thing from 2 machines running 2 different versions of Linux on 2 different networks.

yo'

1:19 AM

@cfr well, Nobody is here. :D

Paul Gessler

@cfr I get the same error you reported earlier with a search

cfr

1:40 AM

@PaulGessler Good. That makes it a SEP rather than an MP.

@yo' True, but they were when I first asked.

LaRiFaRi

7:05 AM

@JosephWright sorry, he wasn't happy with my answer. tex.stackexchange.com/q/224159 Are you taking a look? I asked him in my comment to be patient on what you say...

Joseph Wright

@LaRiFaRi You've got this right

@LaRiFaRi 'Traditional' units don't follow any particular rules, so there is a limit on what can be done

LaRiFaRi

@JosephWright I guessed so. You could write that stuff in your package... But: why?

@JosephWright Yes, I understand.

Well, write that as an answer and he will accept. (as he says)

Joseph Wright

@LaRiFaRi It's for example possible to define settings for a named unit, so with \DeclareSIUnit[per-symbol = p]\mph{\mile\per\hour} (untested) you can convert to a particular form, but if he's defined \mile as mi that won't help

@LaRiFaRi You've already answered: I don't know what I can add

@LaRiFaRi There is a get-out which is a bit evil!

LaRiFaRi

@JosephWright allright. I will put some quotes from you to my answer and done...

Joseph Wright

@LaRiFaRi The whole point of siunitx is that it deals in consistent formatting. For example, if you say \mile is mi then it should always be mi

LaRiFaRi

7:10 AM

@JosephWright You don't have to explain that to me :-) I am one of your packages votaries

Joseph Wright

@LaRiFaRi The only get-out I can think of is you could define \mile as a 'plain' macro not a unit. It could then do a look-ahead for \per and if found for \hour, and depending on the outcome print mi (if the look-ahead fails) or mph (if it succeeds).

LaRiFaRi

@JosephWright I was thinking about that to. But I can find no pleasure in programming that right now.

...about that, too. uh, still too early for English...

Joseph Wright

\makeatletter
\protected\def\mile{%
  \@ifnextchar\per
    {\mile@aux}
    {mi}%
}
\protected\def\mile@aux\per{%
  \@ifnextchar\hour
    {mi\per}%
    {mph\@gobble}
}
\makeatother
\documentclass{article}
\usepackage{siunitx}
\begin{document}

\si{\mile}
\si{\mile\per\minute}
\si{\mile\per\hour}

\end{document}

@LaRiFaRi ^^^

A bit risky but will more-or-less work

@LaRiFaRi Should I post that as a separate answer?

LaRiFaRi

Why not... I was just adding your quotes to mine, but I stop that.

@JosephWright If he really is in need for that due to his XML stuff, this would be a valid (even if hackish) solution

Joseph Wright

@LaRiFaRi Option b I guess is to do \let\savedSI\SI (or similar) and then just check the argument grabbed. I'll post an answer in a bit.

LaRiFaRi

7:19 AM

\sisetup{per-mode=fraction} does not work for your first MWE

@JosephWright Well, have fun! :-) Thank you.

Joseph Wright

@LaRiFaRi Yes, I know: it is a hack

Anthony

7:37 AM

Ayo!

@JosephWright What's the best way to log dates, like a journal entry? At first I thought of using \today but then all the dates will be the same...

egreg

7:58 AM

@Anthony \logentrydate{2015}{01}{21}, with a suitable definition for \logentrydate.

Anthony

@egreg So this just takes care of formatting then?

Oh also, I'm not using the journal class, if there is one. :P

egreg

@Anthony Whatever you want. It's not a TeX question: if you want that today's date is logged, it's something your text editor program should do. When you compile a file, TeX can access only the current date, not guess what was the date when the document was typed in.

Anthony

Yeah. Thanks!

Morning! This has to be a dupe, but I didn't find it ... :(

Q: defining drop shadow as makro not allowed?

Is it really not possible to define drop shadow (with or w/o options) as a makro? \documentclass{scrartcl} \usepackage{tikz} \usetikzlibrary{shadows} \newcommand{\test}{drop shadow={shadow xshift=1ex}} \begin{document} \begin{tikzpicture} \node[rectangle,fill=red,drop shadow={shadow xshift=1ex}...

Anthony

Morning! (Night here. :P)

Joseph Wright

9:02 AM

@yo' It's the old 'keyval methods do no expansion' :-)

yo'

@JosephWright well, indeed, but where ? :)

and needed to say, I've done the \edef dirty works before.

Joseph Wright

9:15 AM

@yo' Hmm, we have several questions on this but I'm not sure if we have one 'totally general' one

yo'

@JosephWright well, that's the problem. (That's also why I decided to give an answer rather than comment + close vote)

Johannes_B

@cgnieder Call me crazy, but i would have said the citavi question i rolled back had an answer before that was gone after the rollback. But i didn't really pay attention.

Joseph Wright

@yo' Perhaps we need to set up a general question/answer for duping?

yo'

@JosephWright yep. And zap them all! :D

Joseph Wright

@DavidCarlisle Odd think with that issue from yesterday: testing on my Windows machine, the script does stop properly if the errorlevel isn't 1. There might be something odd going on with os.exit that only shows up on Unix systems. Will test later today on my Mac.

egreg

9:20 AM

@JosephWright I read the comment about \XeTeXcharclass when the train was approaching the station: \afterassignment was obviously the answer. Too bad people keep asking XY questions.

Joseph Wright

@egreg Well yes

A: Can you be 1/12th Cherokee?

This depends on the model. Instead of arguing that we have only $46$ chromosomes and cross-overs or whatever the mechanism is called are not that common, let us assume a continuous model. That is, a priori, everybody can be $\alpha$ Cherokee for any $\alpha\in[0,1]$ and the rules are as follows ...

@egreg Doen't line-end normalisation predate web2c: Knuth says something about it in The TeXbook I think

egreg

9:32 AM

@JosephWright Knuth refers to a different thing. With TeX implementations that didn't use Web2C (OzTeX, for instance), files coming from DOS ended up with \par between any two lines.

cgnieder

@Johannes_B I don't think it had but I'm not sure either

Joseph Wright

@egreg Ah

David Carlisle

@JosephWright tex itself makes the whole thing system dependent and says the implementation must report the "lines" with trailing white space removed. So it worked on systems that had a record based structure without a specific line separation char at all, so I think it is web2c that decided to uniformly normalise line endings on the platforms it supports

David Carlisle

9:47 AM

@JosephWright you got mail:-)

Joseph Wright

9:57 AM

@DavidCarlisle, @egreg One of you going to tackle the web2c question?

David Carlisle

@JosephWright @egreg's answered in comments so just make that an answer I think

yo'

3:22 PM

I think I've got a result! (well, a partial one: we've got two conjectures (C1) and (C2) and I think I've got a proof that (C1) => (C2))

this means I'll have something to sumbit to teh conferencez

Johannes_B

Anybody with knowledge on LaTeX and tablets? latex-community.org/forum/…

Just read this question tex.stackexchange.com/questions/213258/… that was on the top of main and thought, that's gotta be a dupe. There was some patching involved. Turns out, i answered that question.

David Carlisle

3:37 PM

@JosephWright fixed a few more typos in ltnews, but nothing requiring a rebuild I think:-)

yo'

3:47 PM

Is there a way how to install vanilla TL2012?

David Carlisle

@yo' tug.org/historic/systems/texlive

Joseph Wright

@DavidCarlisle I'm sure there will be more :-)

yo'

4:13 PM

@DavidCarlisle ah thanks

David Carlisle

@yo' that's bad news, it means now you have only got one conjecture

yo'

@DavidCarlisle Well, the point is, (C1) itself is true certainly, we just don't have a proof, and (C2) is the interesting one

David Carlisle

@yo' :-)

David Carlisle

5:03 PM

@JosephWright new luatex I see....

Joseph Wright

@DavidCarlisle Yes

@DavidCarlisle Will be interested to see what impact this has once I install TL2015 pretest

yo'

5:50 PM

Do you have any trick how to switch different versions of TeXLive quickly?

Paulo Cereda

@yo' Path priority. :)

yo'

@PauloCereda well, I'll see if I manage to put that in different options in TeXworks :)

Paulo Cereda

@yo' oooh :)

yo'

@PauloCereda well, you can create pdflatex10.sh with something like PATH=.../2010; pdflatex $1 $2 $3 $4 $5

[root@toheshiba ~]# cd /usr/local/texlive/
[root@toheshiba texlive]# ls
2010  2011  2012  2013  2014  texmf-local

^^ testing can begin :D

Paulo Cereda

@yo' LOL

yo'

5:55 PM

@PauloCereda It's important, I have to see what I can do before I agree it will be TL2012-compatible

anyways, the TCS+ talk starts in 3 minutes and I need to get a coffee yet. See you later!

David Carlisle

6:35 PM

@yo', @JosephWright I don't think saving the original optional argument so a KV option handler can use it instead of the mangled one works. Just saving the tokens doesn't help you also need to make them safe in the existing option handler, and I'm not sure that's possible in any compatible way:

\documentclass[foo={a,b,c}]{article}

\stop

Joseph Wright

@DavidCarlisle Yes, my concern too

@DavidCarlisle Read kvoptions-patch?

David Carlisle

@JosephWright of course not:-)

@JosephWright see the start of the history section in that:-)

Joseph Wright

@DavidCarlisle I like the introduction :-)

@DavidCarlisle Ah

David Carlisle

@JosephWright noticed that, I got to about page 4, then I thought "I think I wrote something like this", skipped to history section and saw that confirmed..

Paulo Cereda

7:09 PM

@JosephWright Show off. :P

yo'

7:20 PM

@DavidCarlisle what's wrong with this (other than unused options warning)?

@PauloCereda The book arrived!!!

Paulo Cereda

@Brent.Longborough Yay! :)

@Brent: I should never doubt the Royal Mail. :)

Brent.Longborough

@PauloCereda I just spoke to my "manager" at home. She said the wrapping was a bit torn, so she opened it, then thought the book looked very interesting, and has read a lot of it already! I know it's Tschichold, but Google hangouts fell over before I could discover whether it's in English, Portuguese, or German?!?

@PauloCereda Thank you. A really wonderful present in any language.

Paulo Cereda

@Brent.Longborough Believe it or not, it's Portuguese! :)

@Brent.Longborough My pleasure, my dear friend. :)

Brent.Longborough

@PauloCereda Ah, that's why she kept referring to "A Forma do Livro" LOL

yo'

7:25 PM

@Brent.Longborough what an euphemism :)

Brent.Longborough

@PauloCereda As we normally talk in Portuguese, I couldn't tell whether or no she wqas translating the title !!!

Paulo Cereda

@Brent.Longborough LOL

Brent.Longborough

Unbelievable. I was in the middle of shutting down for bedtime, but I had tocome bak to say thank you.

Paulo Cereda

@Brent.Longborough No Welsh? I'm disappointed. :)

@Brent.Longborough <3

Brent.Longborough

OK, I will now amaze you all by turning into a pumpkin in Comic Sans. Goodnight all...

Paulo Cereda

7:29 PM

@Brent.Longborough G'night, Brent! :)

Joseph Wright

7:43 PM

@DavidCarlisle Do you think it would be OK to change ltvers to do \everyjob\expandafter{\the\everyjob\typeout{\fmtname (i.e. keeping anything present at the start of latex.ltx)?

@DavidCarlisle Context: there's one thing outstanding from lualatex.ini: the 'quote the job name' business. My feeling is that the code itself there is web2c not format related, so still belongs in the .ini, but it would be easiest handled if we leave anything present in \everyjob at the start of the format building alone.

David Carlisle

@yo' yes if you don't use the standard option handler at all it's a bit safer. But most classes want to pass options to article (for 12pt or twoside or whatever) and I'm not at all sure that the behaviour in most cases is documentable:-) will think about it.

Joseph Wright

@DavidCarlisle Heiko's code uses e-TeX a lot, and it's quite dense

hhh

This problem of not getting references compiled in OSX is appearing again. How is it with your OSX? Can it be caused by some update in OSX? (I just updated everything with Texlive Utility and did not fix the problem so now puzzled how to approach this problem of not getting references compiled).

http://tex.stackexchange.com/q/212540/2956

David Carlisle

@JosephWright what a shock:-)

yo'

@DavidCarlisle well, you can allow the class to handle it itself (including \LoadClassWithOptions and stuff. The classes would have to choose: either completely what it was until now, or completely the new thingy.)

Joseph Wright

7:56 PM

@DavidCarlisle I've added a couple of .ini files to DropBox, but the LuaTeX relies on fixing that last point

David Carlisle

@JosephWright probably, was just reading it now,

@JosephWright how come dropbox told me that you'd added the ini files, did you explicitly share that with us as well as giving the http address by mail?

Joseph Wright

@DavidCarlisle I shared the folder: I think if you grab them while logged into DropBox it 'remembers' that you have access

David Carlisle

@JosephWright anyway they look lots nicer than the existing ones!

@JosephWright everyjob looks OK, probably should flag it on team list though

Joseph Wright

@DavidCarlisle Yes, just thought I'd ask first in case there was anything to watch out for

David Carlisle

@JosephWright no, don't think so, other place of course to do it would be the end (where ltpatch.ltx does/did it) but so far we've avoided having a cfg file at that point so doing it at the start is OK I think.

@JosephWright do you think it would be worth starting the extended allocations at (say) 266 rather than 256 so leaving 10 for special uses (etex did something similar for its counts for the local/global stuff. In particular could then steal 256 and 257 for use in \newmarks and \newxetexcharclass which would save using \newcount for those which uses up a classic register and changes all the numbers in the test logs....

Joseph Wright

8:10 PM

@DavidCarlisle Sounds fine to me

David Carlisle

8:51 PM

@JosephWright mail sent, not sure who's around apart from us though:-)

Joseph Wright

@DavidCarlisle Indeed

@DavidCarlisle Like I said, plan sounds solid to me and does leave space for a 'second round' for LuaTeX-specifics (some stage in the future)

David Carlisle

9:10 PM

@JosephWright permalink.gmane.org/gmane.comp.tex.luatex/848

Joseph Wright

@DavidCarlisle Ah yes, that's the one

@DavidCarlisle Odd think thought is presumably for pdfTeX it's done at the web2c level not in the original sources

David Carlisle

@JosephWright I think it's in the web change file though (or at least I think I recall seeing something about that once) so presumably not code shared with luatex anymore

Joseph Wright

@DavidCarlisle Probably

Joseph Wright

9:35 PM

@DavidCarlisle Great irony of course is that for the end user of LuaTeX/LuaLaTeX it actually acts the same :-) (ConTeXt MkIV of course different)

David Carlisle

@JosephWright one suspects for the developers, it's only really the last of those that matters;-)

Joseph Wright

@DavidCarlisle I've had some interesting direct mails, to be sure

David Carlisle

@JosephWright re bug reports?

Joseph Wright

@DavidCarlisle Indeed

@DavidCarlisle And re blog posts

David Carlisle

@DavidCarlisle No, see logo at bottom of CTAN page

@barznjy Hello

barznjy

I have a question about figures in latex;
How I can reduce the space between the figure and its caption?

David Carlisle

@JosephWright www.ctan.org? don't see anything

egreg

@JosephWright A name?

David Carlisle

@barznjy depends on class/packages but in article you can \setlength\abovecaptionskip{2pt} (default is 10pt)

barznjy

I use the following
\begin{figure}[htp]
\centering
\includegraphics[scale=0.53]{fig1}
\caption{System model}
\label{fig:fig1}
\end{figure}

Joseph Wright

10:00 PM

@DavidCarlisle Perhaps it's just me, then

@DavidCarlisle Ah, reloading it's off on the left-hand side and 'grows' when you go near it

David Carlisle

@JosephWright I see it in view source: xing.com

barznjy

@DavidCarlisle what about if I use IEEE style?

yo'

@barznjy do you prepare a conference or journal paper?

barznjy

conference

@yo' it is for IEEE conferences

yo'

@barznjy then the answer is simple: don't do it or it can be a reason for rejection.

barznjy

10:14 PM

@yo' may be you know that some of the conferences restricted the number of pages, therefore, you don't want to have an extra page for one sentence.

yo'

@barznjy I do know this. Try \usepackage{microtype} that one hasn't been blacklisted yet I think

or make the figure itself slightly smaller

barznjy

@yo' but how they know if it is used or not? because you are usually submit pdf file

yo'

I wouldn't dare juggling with the page layout

@barznjy well, if you submit a pdf file then you're probably safe.

barznjy

@yo' all IEEE conferences accept only pdf submission

yo'

You can try putting \vspace*{-1.5\baselineskip} between the figure and the caption (separate it by an empty line from the figure)

barznjy

10:18 PM

@yo' so, could you please give me some detail of how I make the space between the figure and its caption smaller ; for example for this case

\begin{figure}[htp]
\centering
\includegraphics[scale=0.53]{fig1}
\caption{System model}
\label{fig:fig1}
\end{figure}

yo'

@barznjy you know how it works: Create a MWE and then it's simple. Without it, it's impossible

David Carlisle

@barznjy see the comment on the line above

barznjy

@DavidCarlisle I used your command but nothing changed

David Carlisle

@barznjy Yo's command will work in any class

yo'

@DavidCarlisle well, it's just a very dirty trick, these work the best.

David Carlisle

10:22 PM

@yo' whereas mine is pure and elegant and not working:-)

yo'

@DavidCarlisle OTOH, there're no bugs in your packages whatsoever

David Carlisle

@yo' of course not

barznjy

@yo' It works, great ..... many thanks for both of you

yo'

@barznjy you're welcome. However, if you prepared a MWE next time, it would have taken us together half of the time and effort to solve the problem

David Carlisle

@yo' but less opportunity for mutual insults

barznjy

10:25 PM

@yo' what is MWE ?

yo'

@DavidCarlisle sure. Now excuse me, I should leave my office, it's 11:30 PM

@barznjy minimal working example (MWE)
