9:39 AM
Hello all
 
10:01 AM
@JosephWright Re the question on the angstrom: I get the message Missing character: There is no Å in font cmmi10!
 
@egreg With what MWE?
 
\documentclass{article}
\usepackage{amsmath,siunitx}
\usepackage{unicode-math}

\setmainfont{XITS}
\setmathfont{XITS Math}

\begin{document}

\si{\angstrom} $\si{\angstrom}$

\end{document}
 
@egreg Sounds likely
 
@JosephWright ^^^^ with XeLaTeX and LuaLaTeX
 
@egreg Like it says in the manual, the standard settings are OK for pdfTeX/'TeX fonts', but once you go outside of that you do have to set things up yourself
@egreg There are simply too many combinations of packages, etc., otherwise
 
10:06 AM
@JosephWright Yes, if unicode-math is not loaded, the symbol appears. Maybe checking for it is not too difficult.
 
@egreg Problem is that I can't know what the font coverage is under those circumstances
@egreg Perhaps for v3: I am working on it!
 
@egreg thanks for the command, but I don't understand it.
@egreg In my MWE, there is no $\AA$ defined. unicode-math calls this symbol $\Angstrom$. So I understand that the mapping of the xits-math font is set to $\Angstrom$ but siunitx wants to use a slightly "corrected" $\AA$
 
@LaRiFaRi Useful to know: I can pick up unicode-math and redefine things. Expect an siunitx update :-)
 
@JosephWright thanks. Nice to hear that. I am on unicode-math since a while... But luckely I do not need ångström for my stuff.
How do you define `\angstrom` in your package? \begingroup
\let\protect\show
\angstrom
\endgroup does not work and there is no source in your doc
@egreg I will delete my answer. Joseph extracted the good parts and will work on this. much better... The result of my answer is not really pleasent, as siunitx seems to manipulate something when calling \angstrom. I thought it would be just some \mathrm{\AA}... But well, no time to check that now.
 
@LaRiFaRi With the standard settings, the unit macros are only available inside the argument of \SI and so forth
@LaRiFaRi The standard value is \text{\AA} in math mode and \AA in text mode
 
10:19 AM
do you know some command as \show in order to call your macros?
 
@LaRiFaRi Not currently: they are internal
@LaRiFaRi I can think about this for v3
 
@JosephWright ok. Thanks. Ah, no, no need. I just found out the \show and was using this on everything since then :-)
@JosephWright I guess the source of your package is somewhere around and you could read that definition there. (and pinging you is even quicker than \showing some macro)
 
@LaRiFaRi Erm, it's a bit complicated :-)
 
@JosephWright You may choose: Documentation, cool new feature or 24/7-reachablity in chat...
@JosephWright You should not consider that topic. There are really not many cases, someone is aksing for your definitions here. As your package does work most of the times.
@JosephWright Are you sure about your angstrom definiton? \renewcommand{\SIUnitSymbolAngstrom}{\ifmmode\text{AA}\else\AA\fi} does work for the problem above
@JosephWright sorry, forget that. At the moment, I am not anymore able to reproduce the original problem. It works all the time.
 
10:50 AM
Good MAEN ;-)
 
11:10 AM
Hello everyone, I cannot seem to force a caption of a table to be below the table instead of above it. Any good ideas?
pastebin.com/Umh76Gvd is the table in question
 
@Argo: We prefer not to follow links ;-)
 
\begin{table}[H]
\centering
\begin{tabular}{c c c}
	Prøve & Konc. & ABS \\
	\hline
	0 & $0$ & $0,245$ \\
	1 & $1,321$ & $0,458$ \\
	2 & $2,641$ & $0,661$ \\
	3 & $3,962$ & $0,854$
\end{tabular}
\caption{Gennemsnit af absorbans for de to første soomething} % skal rettes
\label{tabel1}
\end{table}
 
@Argo: Which class/packages do you use?
 
@Argo With no packages loaded it will be, so there is more going on
 
I'm using, among a bunch, the float and tabularx package
Doesn't seem to be those two
 
11:18 AM
@Argo neither of those will move a caption by default
 
\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc} % UFT8 - danske bogstaver og andet godt fra havet
\usepackage[danish]{babel} % dansk sprog et-eller-andet
\renewcommand{\danishhyphenmins}{22} % dansk orddeling
\usepackage[T1]{fontenc}
\usepackage{amsmath} % noget matematik
\usepackage{amssymb} % mere matematik
\usepackage{bm} % bold symboler
\usepackage{mathtools} % en række matematik-ekstra, bl.a global no-numbering
\usepackage{xcolor} % en masse farver
\usepackage{siunitx} % SI-enheder
The packages I've loaded
 
@Argo this is why fragments of examples are pretty useless and we always ask for "MWE" ie small complete documents that show the issue
 
Without any packages everything is fine (caption is below table)
 
@Argo: At first glance there is no package in your list which influences the caption position
 
@Argo so you can work out which package it is as well as anyone, just put them back one at a time until the caption moves
 
11:23 AM
@Argo: After seeing the full text ... I withdraw my statement...
@Argo Do you really need the full bunch of packages at all?
 
Nope, it's just a habbit of using the same preamble. When I encounter a problem or need a specific feature provided by a package, I add it to my preamble. I could probably remove half of those packages.
Found it
 
@Argo: If you are sick, you won't swallow pills against all diseases, would you?
 
Obviously not
But I find it to be a way to have all my knowledge about those small hacks and tricks combined into a single place nice
\usepackage[floatrow=false]{chemstyle}
Was the sinner
 
@Argo No, it's deliberate there :-)
 
... Why?
 
11:33 AM
@Argo chemstyle follows the style of publications in the area: they use table captions above the content (pretty common for most publishers to be honest)
 
Ah
Now I see
Thanks
 
and today's aim: score 100 while having an even number of accepts....
 
12:06 PM
@JosephWright A last comment on the above problem: Your package " siunitx.sty 2013/07/31 v2.5s A comprehensive (SI) units package" does work here. So it seem that you changed something on the angstrom between versions.
 
@LaRiFaRi Huh?
@LaRiFaRi Might be the switch back to math mode as by default for units
 
@JosephWright strange, isn't it? That's why I couldn't reproduce the error... Updated now and checked with your older version of github.
 
@LaRiFaRi Not really strange: I have a warning in the docs about Unicode-based font set ups as they are really not so easy to predict (although I will try to extend things a bit)
 
@JosephWright that sounds reasonable. $\AA$ does not work in in the MWE and you are forcing exactly this in your new version
 
Roll on LaTeX3 and pre-defined interface for all this stuff
 
12:16 PM
@JosephWright OK, thanks. anyway, seems like the OP just wanted to provide a complete set of Q&A and does not want help here. No "babysitting" needed...
 
@LaRiFaRi Nope :-)
@LaRiFaRi When fontspec is loaded the package switches to using \char197 which (often) is a 'proper' ring-A
 
Hey guys. What's LYX?
Sep 11 at 19:55, by Paulo Cereda
user image
 
haha... something bad I suppose...
@Khallil LyX is some kind of LaTeX-Editor which does not need a real LaTeX-input.
 
@Khallil It's a system which uses LaTeX as a back-end but provides a GUI for 'what you see is what you mean' input
@Khallil Some people find it a good way to get the power of LaTeX without needing to code
 
Aha, thanks!
 
12:22 PM
@Khallil the cartoon shows that it is something between TeX and Word... You have Word-like input and TeX-like output. Thats why both parties think its bad... (just explaining the picture. Thats not my opinion as I do not use and know LyX
 
@LaRiFaRi I'm looking at this: will probably update siunitx later today :-)
 
@JosephWright some more observatoin. amsmath and unicode-math produce an "Package amsmath Warning: Unable to redefine math accent \mathring." (also without your package or any use of \AA). Don't know, if this is something to consider...
 
@LaRiFaRi That's a load-order thing with unicode-math and amsmath, I think
 
@JosephWright yes, it is. stupid me... Good, one problem less
@JosephWright thanks for looking at it. And good luck.
 
12:40 PM
@LaRiFaRi It seems that the font system doesn't really do a good job on falling back to canonical equivalents (e.g. 'ring A' = 'angstrom' but only the latter works in math mode with some fonts)
 
 
1 hour later…
1:56 PM
@DavidCarlisle Did you see the Minecraft news?
@LaRiFaRi Update for siunitx sent to CTAN
 
@JosephWright the other day bbc were predicting microsoft would buy
 
@DavidCarlisle Must have an inside person :-)
 
Sep 11 at 11:48, by David Carlisle
@PauloCereda I wonder if @egreg would also change his mind about M.S. if they offered him 2billion dollars? http://www.bbc.co.uk/news/technology-29142975
 
2:19 PM
@percusse I'll see if I can raise your meta question with the Powers
(Probably later today so daytime US time)
 
3:13 PM
@JosephWright great. Thanks. I am just reading tex.stackexchange.com/q/201241 and I remember that I already have wanted such stuff once before. Is there a planed feature such as [table-format=\SI{1.3}{s}]?
 
@LaRiFaRi No
@LaRiFaRi With hindsight I think the s column was not a great idea at all
@LaRiFaRi In almost all cases a table of numbers should be used to allow comparison, so units are really no appropriate
 
@JosephWright hmmmm, I never needed it. Not such a timesaver
 
@LaRiFaRi In the small number of cases where that is not the case, using collcell and then just \si{...} is appropriate
 
@JosephWright I would say, you are right with that. But in real-life, I am having mixed tables all over the place.
 
@LaRiFaRi My current development plans are focussed around what I feel would be best for a 'pure' LaTeX3 version of the code, where I'd like to drop a few things but do the core ones better
@LaRiFaRi Likely: a table is not the best presentation format
 
3:16 PM
@JosephWright true, these tables look bad.
@JosephWright well, keep on track with your plans. Just read the post and thought: "you could ask for the reason"...
It's not difficult for me to set such tables. But as many new users are having problems it could be handy.
 
Good MAEN;-)
@egreg: Thanks for editing ;-) I was unsure about the grammar ... it didn't look nice ;-)
 
@ChristianHupfer “even then, if” seemed quite German to me. ;-)
 
@egreg: Yes, a false friend, somehow ;-)
 
@ChristianHupfer As a general rule, English doesn't use a comma after the relative pronouns (“that”), unlike German.
 
@egreg: Yes, I remember such things, from school ;-)
 
3:28 PM
@egreg English uses commas mainly at random :-)
 
@ChristianHupfer You can easily recognize German from plentiness in uppercase letters and commas.
@JosephWright Well, the whole grammar is random.
 
@egeg: It makes German language outstanding :-P
 
@JosephWright That's the main problem when teachers want to teach English by grammar; it's so different from the Italian grammar that this method is mostly useless for learning the language.
 
4:22 PM
@JosephWright Thank you. I don't have much hope either but it's anyway good to know where we stand with respect to their view.
 
@percusse Yes
 
@JosephWright Annoying them a bit is also a success :P
 
@percusse The mod team can ban individuals from reviewing, of course, but that would not address the issue I think you are primarily getting at
@percusse I've mentioned this in the mod chat, but no response as yet from the Powers
 
@JosephWright Yes I don't promote such drastic measures. But there are no means to apply pressure on individuals. It's a totally a one-man show. And as I mentioned it's reassuring. Example, these numbers are totally abnormal tex.stackexchange.com/review/first-posts/stats and since I've revealed my opinion before I can do it again; Papiro is not a good reviewer.
But there is no way to stop his offline queuing
 
@percusse I can see the lack of 'feedback': despite the 'community' model it's actually very hard to bring any peer pressure to bear on the review process
 
4:31 PM
@JosephWright We can elect reviewers too so that people who are willing to review continuously can be nominated and the system directs the reviews to them instead of the fastest automated user.
 
@percusse Certainly an idea: one for the main meta site I guess
 
Because the algorithm is provably susceptible to alteration and also using positive feedback
So any stupid behavior if repeated enough times gets reinforced
 
cic
does anyone recognize this symbol? i.stack.imgur.com/0i5gR.png
i.e., how to write it in latex
(i tried detexify and it didn't work)
 
@cic Is it a caligraphic P?
Where did you see it?
 
cic
In "Foundations of Modern Analysis"
 
4:42 PM
@percusse Or, maybe, a calligraphic A
 
cic
yeah, i think it's an a
 
@cic Friedman?
 
cic
yes
it was used for a sigma-algebra
 
@cic These ones?
 
 
4:44 PM
 
cic
yes
 
@cic ^^^^ That one is in the MathTime Pro fonts (not in the Lite version, I'm afraid).
 
@egreg Ah, figures...
 
cic
so it's not a standard latex symbol?
 
@cic It's just a calligraphic A, the actual shape is unimportant.
 
4:47 PM
@egreg Is that the \mathscr{A} or \mathcal{A} equivalent?
 
@percusse It's a question of personal preference.
 
cic
ok, i'm going to use a standard $a$ instead and then just add a footnote saying that the character looks different in the book. thanks.
 
@egreg I should ask if I load MTPro which one leads to that symbol by default.
@cic It's just a letter A-lgebra. You can use Alpha-gebra or whatever
 
@percusse If you have the full version
 
cic
You mean that it's totally arbitrary what symbol to use? Yes, but i wanted to refer to a set specified in one of the exercises :/.
 
4:54 PM
@percusse \mcurly
@cic Just do \mathcal{A}.
 
 
2 hours later…
6:48 PM
hi @percusse. thank you for your opinion about my reviews.
 
7:03 PM
@percusse as my (first post) reviews are bothering you, I will stop make them. Good luck and have a nice time. Peace!
 
7:52 PM
Hello, ladies and ... non-ladies. How can I take a look at the latex 3 source code? The basics like \c_one and so on, a list of commands available in expl3?
 
@1010011010 texdoc interface3 for the interfaces, or if you want to see the code texdoc source3
@1010011010 Unless you really need to I'd stick to interface3
 
@percusse not in all fields. AFAIK some mathematical physicists suffer from a lack of alphabets, so they distinguish the calligraphic and script capitals
 
Eeeexactly what I was looking for. Thanks.
texdoc source3 returns nothing. :-(
 
@tohecz: Hello, how was you exam?
 
@ChristianHupfer you mean the one tomorrow? :D
 
7:55 PM
@1010011010 Something is wrong then
 
@tohecz: Ooops, sorry, I thought it was on Friday? ....
 
I'll update my distribution. Maybe it's that.
 
@tohecz: I wish you good look and much success, of course !!!!
 
@ChristianHupfer tomorrow at 11am CEST
 
@1010011010 We had a few releases with missing files, but that should be sorted now
 
7:57 PM
@tohecz: I'll keep my fingers crossed for you!!!
 
@ChristianHupfer thanks pal!
I'm afraid I'll need that
 
@tohecz: Is it a defense?
 
@ChristianHupfer no, it's called a "rigorous" or "doctoral state" exam
 
@JosephWright TeX Live Manager crashes when I try to update any package at all. Can I do this manually?
 
8:02 PM
Thanks.
 
btw, how do you pronounce CTAN? similarly to Seton?
 
@tohecz: Ah, yes, the criss - cross exam ;-)
 
@tohecz 'see-tan'
 
@tohecz: It'll be good!!!! Don't mind!
 
What's wrong with See Tee Aye En?
 
8:04 PM
@JosephWright ok thanks. And Seton is see-tonne right?
@ChristianHupfer the criwhat?
 
@tohecz Yes, more or less
 
@1010011010 it's too non-English long
 
@1010011010 More natural in English to make it a 'word'
 
@tohecz: criss-cross ... means something like -- it can go in any direction, concerning any topic ...
 
I once had a conversation with someone in Germany about ADAC, the breakdown people there. In English, 'ay-dac' is natural but apparently in German they stick to the initials.
 
8:06 PM
@JosephWright: Don't mention the ADAC ... those cheaters :D
 
@ChristianHupfer not quite. There's three exams + the progress report
 
@tohecz: My doctor 'rigorous' was such a criss-cross -- the whole bunch of Physics, from Quantum Statistics, QFT, a little bit on General Relativity, but almost nothing about my own subject -- Astrophysics ... 2 hours can be long ;-)
 
@ChristianHupfer not that long here. it's 3x15m for subjects, then 15m for the talk and ~15m for the discussion. It should total 75 minutes, usually it's a small bit longer due to some pauses and stuff
 
@tohecz: Pauses? :D There were no pauses in my exam. Two hours in front of three professors, firing questions on me
 
@ChristianHupfer well, not really pauses, but you know what I mean, nobody is quite in a hurry there ;)
 
8:15 PM
@tohecz: Well, yes ... good luck then!
 
@ChristianHupfer thanks
I'm briefly going through my notes again, and I'm polishing the slides
 
Has anybody 'seen' Johannes this evening?
@percusse: You upset Papiro... ;-)
 
@Papiro If you want to discuss be a little less childish. I have tried to discuss this issue i don't know how many times here or in comments. So if you will I'm not even bothered until you make a proper argument.
Everytime I try to draw your attention you are practically invisible but whenever your name is mentioned you show up in the chatroom in miliseconds. So next time, stay here and make a proper sentence about the problem not sarcastic remark
You can also answer my question on Meta
Because I would prefer having TikZ porn instead of chasing wrong votes and first post reviews.
 
@percusse As I said on the meta question, I think focussing on the 'big picture' rather than individuals would be best
 
@percusse I had a friend ( a group theorist) who had an article in the journal of algebra I remember him insisting that they find four visually distinct calligraphic/script/curly/whatever ''p''
 
8:28 PM
@DavidCarlisle :-)
 
@JosephWright Perfectly true. But I don't know any other way other than confrontation because a single person deciding in the name of everyone is also not right but anyway. I'll leave it at that.
 
@DavidCarlisle They could try Thai and Devanagari.
 
@DavidCarlisle They probably have very clever ideas that cannot be simplified.
@JosephWright Added some clarification
 
8:47 PM
@percusse Amen. :D
 
@percusse childish? hehehe.... I have no time to discuss with you, sorry. I will not answer your question on meta. Good luck with your TikZ porn. I am not deciding in the name of everyone... I am rewiewing in my proper name, of course.
Have a nice time...
 
@Papiro Ah you are here.
Wait
Why did you even come back? Haha man these online personas, they are all one in a million. But in total they are more than a million.
Surreal numbers...
 
9:03 PM
@percusse I can't help myself, but someone is only making fun of all the other people here.
 
@tohecz Nevermind. We still have some room for a few strange ones.
 
@Papiro well, if you don't have couple minutes to discuss the site's moderation and reflect the opinions of other people, just please stop moderating. Simple as that.
 
@tohecz Did you fix your electrical network without electrocuting yourself?
 
@percusse I dropped that project for now, 've got more important stuff to do
 
@tohecz Like staying alive ? :P
 
9:07 PM
@percusse you are mean, remember I've got a tough exam tomorrow please
i'm really nervous and very unstable thus :(
 
@tohecz I think you mean reviewing
 
@tohecz Yes, I'm sorry. After getting out of academia, I lost the sensitivity to those matters as a reverse psychological reaction
 
@JosephWright well, community moderation includes more than that: up-voting, commenting, actively looking for duplicates etc. It's not obvious from my post that I mean this, right?
 
@tohecz He is jealous because he is the moderator :P
 
@percusse no worries, it's more a warning that I could easily say something bad without the actual intention, only to regret it tomorrow when I see it from distance :(
 
9:10 PM
@JosephWright No worries we still worship you and bring you beheaded sheep and cows :P
 
@percusse Amen.
 
@tohecz What's the exam about?
@PauloCereda It is again time for the annual reminder for
I have a project in mind, but it's still a work in progress. :(Paulo Cereda Aug 15 '12 at 12:07
 
@percusse doctoral state exam. Three subjects (automata with multiplicities, symbolic dynamics, rational operations on continued fractions), then a thesis progress report and a discussion about it
 
@tohecz Whoa, that's pretty much nuances in chinese dialects.
Hope it goes well
 
@percusse well, same here
 
9:17 PM
@tohecz Lately I've been into mathematical physics a bit and that's where I learned briefly about continued fractions. Amazing subject but no less than voodoo magic.
I'm still wrestling with Shanks and Richardson approximations.
So quite beginner
 
@percusse well, one of the professors is an expert in generalization of these numeration systems (ways how to write a number as a sequence of symbols) to the most possible extent if you want to keep writing down only real numbers. He's a weirdo :)
 
@tohecz I think that's a precondition to study these things
 
@percusse being a weirdo? quite yes, yeah :D
 
@JosephWright fancy doing a bit of javascript? github.com/mathjax/MathJax/issues/447#issuecomment-55527104
 
9:52 PM
@tohecz For your question, in the doc folder of TeX Gyre there are individual PDF files for showcases
 
10:03 PM
@percusse it's funny, the files are named by the 3-letter codes. How in the world I am supposed to know them?

Q: Berry naming scheme list of LaTeX font families

Harold CavendishCould you provide me with a list of Berry names for LaTeX font families? I am currently working on a paper comparing various LaTeX fonts, particularly their support of extended Latin and it took some time to figure out these obsolete three-letter codes for the TeX Gyre families (to change font f...

There you go :)
 
@percusse starts to look like one of these phone services: you need to do 17 steps in order to get a simple thing ;)
however, I just found out that all the test files there contain all the fonts, not only one of them
 
@tohecz There are also test files for them so you can make up your own showcase. For the are code wizardry see page 7 of tug.org/fontname/fontname.pdf
 
and unfortunately, they seem not to be really available through texdoc :-/
 
@tohecz Hi Tom... Good luck in your doctoral state exam. Everything will be ok!
 
10:09 PM
@tohecz Everything comes free comes without a referee as they say. Not all facilities are yet implemented.
 
I would really hope texdoc tex-gyre gave something more useful :(
 
Maybe if you implement the TDS structure properly, they work
There are two files to download
the bigger one is marked as for TeXies
 
@percusse well, I'll just make some texdoc alias I think
@Papiro thanks
 
@tohecz cheater :p
 
@percusse if any of the test files was appended to what you get by texdoc tex-gyre, I wouldn't have needed that
 
10:13 PM
@tohecz Let me see if it will work out on MikTeX localtexmf
@tohecz Nope
 
Thanks percusse and cfr for their help! — tohecz 36 secs ago
