@yo' So what? Change the last kernel function call into your own function call.
 
yo'
@egreg well, the change is actually this :) \cs_set:Nn \@@_set_elt_aux: {}
 
@yo' Don't. This is precisely what should not be done under any circumstances.
@HarishKumar I'm going to bed soon. ;-)
 
yo'
@egreg but tell me what should I do? Fork l3keys.dtx, change it to my liking and keep a forked version?
 
@AdamLiter Have you tried the package optioncompatible-version?
 
@yo' Find a way to do it without changing a private function.
 
12:05 AM
@egreg I know :-) But I felt saying good night will be a sort of forcing you to go to bed :P
 
yo'
@egreg Easier said than done :)
 
@HarishKumar :)
 
@HarishKumar Yes, I've tried both compatible-3.07 and compatible-2.07 but neither seem to work.
 
@AdamLiter You have to see the style file of leipzig find out the glossaries commands and use that option which defines those commands, I hope. I don't have time now but :(
 
@HarishKumar No worries. Thanks for the tip! I don't have much time myself at the moment, so maybe I'll just add a bounty to that old question. :)
Hmm, actually, nevermind. The answer does seem to solve the issue when I actually create a copy of and then change the .sty file. I must have been doing something wrong with \patchcmd.
 
12:48 AM
@yo' It's the official L3 smiley. :D
 
yo'
@PauloCereda lol
 
yo'
1:32 AM
@PauloCereda lol
@PauloCereda BRAZE YOOSELVZE, YO' MODIFIEZ TEH LATEKS3 COREZ! :D
 
@yo' With :D of course. <3
 
yo'
@PauloCereda no, with \__ this time
 
@yo' LATEXOR3 <3
 
@PauloCereda blame Leslie
 
@DavidCarlisle :)
 
1:36 AM
@yo' I assume you're not expecting anyone but @JosephWright to answer that:-)
 
yo'
@DavidCarlisle well, @egreg could be able to answer that one, too :-) I'd be actually quite happy if @Joseph zapped it as a feature request and fulfilled this request. I even know how to do it in the LaTeX3 way.
 
@yo' he'd answer it, but would it be right?
 
yo'
@DavidCarlisle as long as he refrains from any :D macros :D
 
@GonzaloMedina probably was, but I've done the same, force close things quicker than I would have liked as I haven't noticed a tag
 
yo'
@David @Gonzalo it's funny to see how many people are actually unhappy about the golden badge zapper, because they feel that a closure is not a 1-0 thing.
 
yo'
1:58 AM
Time to go to bed (well, I slept for a while in the afternoon, but I need some sleep yet).
@PauloCereda good night!
 
2:15 AM
@yo' Good night, Tom!
 
yo'
@PauloCereda bye!
 
 
4 hours later…
6:41 AM
@yo' Performance, also in the opinion of some team members clarity
@yo' Eek: what are you trying to do?
 
 
1 hour later…
7:53 AM
@GonzaloMedina Welcome to my world :-)
@yo' Indeed: as a mod I get very little say in such things!
 
 
1 hour later…
yo'
9:14 AM
@JosephWright I did not realize that all key setting was local, but it seems that for some reason I decided to use gset rather than set. I'll explain what I try to do.
 
9:39 AM
@JosephWright @GonzaloMedina well in a way it's easier for mods as you know you have that power, but for us, usually we don't, so can take part in community voting, but if you don't double check the tags in the question and remember which tags for which you have a badge, then you may be surprised by the result.
 
yo'
10:04 AM
@DavidCarlisle There was a discusion somewhere mentioning that people wanna know they've got the golden hammer on the question. IIRC, it was declined with "you are supposed to vote in the same way and be sure what you're doing".
 
10:22 AM
@yo' yes I saw that. It's wrong but that's how it is
 
11:15 AM
Let's break LaTeX yaaaay!
 
yo'
@PauloCereda wha?
 
@PauloCereda you have 2015 installed?
 
@yo' break stuff yaaaay
 
yo'
@PauloCereda I lost you completely I think :p
 
@DavidCarlisle Nope. :)
 
11:21 AM
@PauloCereda oh no my usual translation service failed, I thought in English the comment was "I have downloaded the test release and am starting to perform some regression tests"
 
@DavidCarlisle Oh no, I'm too stupid to make things work on my own. :)
 
11:47 AM
SOS quick aid needed:
hyphenation
 
@nuttyaboutnatty Uninstall emacs. Problem solved. :)
 
the word "wholeheartedly" currently pokes out
using
\usepackage[none]{hyphenat}
but want to allow breaking "wholeheartedly" into "whole-heartedly" iff necessary
how?
want to suppress hyphenation generally in an article document, but don't want any longish words protruding either...
so actually don't want [none], but rather some
 
@nuttyaboutnatty if you want no hyphenation use \sloppy to give tex half a chance of linebreaking.
@nuttyaboutnatty you can't allow that as you have just prevented hyphenation, those aims are contradictory.
 
instead of \usepackage[none]{hyphenat} ?
 
@nuttyaboutnatty If you want to allow words to hypenate don't use that package.
@nuttyaboutnatty ie, you want the standard behaviour.
 
11:58 AM
how to forbid hyphenation for individual words?
hyphenation{whole-heartedly nohyphernationhere}
?
 
@nuttyaboutnatty that would work, the default breaks are whole-heart-edly
 
and how would it work for Some\,Collocation ?
 
@nuttyaboutnatty that's two words
 
right
somehow \, is not visible...
that is it looks like SomeCollocation
(and not like Some Collocation)
 
@nuttyaboutnatty well \, isn't a very big space
 
12:04 PM
ok
replaced it with ~
:-)
 
@nuttyaboutnatty why not a normal space?
@nuttyaboutnatty isn't it better to break after Some than break as Some Col- / location ?
 
12:19 PM
@yo' Hope my answer to your keys question makes sense!
@DavidCarlisle I'm with you on \CharacterTable :-)
 
yo'
@JosephWright I'll check that later. now it's time for some real work (and it works in current version, with the bad hack in the core, so people can test everything there)
 
@yo' :-)
 
thanks!
 
1:02 PM
@egreg Can I use for T2A cyrillic some input enconding (?) that doesn't use cyrillic glyph? I mean, to write in english alphabet but to provide cyrillic with T2A? I hopes you understand me
 
@Cortizol yes so long as you do not need any of the accented characters from T1, T2A includes a-z and A-Z in their ASCII positions.
@Cortizol see texdoc encguide page 21 which lists the T2A encoding
 
@DavidCarlisle I see that table, but I am stupid guy :) I mean, when I want to wrote something that looks like: "Зовем се Петар Радовић и положио сам све испите." my code is:

\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage[T2A]{fontenc}
\begin{document}

Зовем се Петар Радовић и положио сам све испите.

\end{document}

I suppose that I should change this utf8x with something? I suppose that you understand me what I want, but, because my poor english, I would like that my document look like
 
@DavidCarlisle Did you see Ulrike's mail?
 
@JosephWright no looking..
 
1:22 PM
@Cortizol T2A is an output encoding.
@Cortizol \renewcommand{\CYRZ}{Z} and so on.
 
@egreg Okay. And how do that for "ж" or "љ" ?
 
@JosephWright would it?
 
@Cortizol Those are \cyrzh and \cyrlje; you find all of them in t2aenc.def
 
@egreg All right. But I have problem, I suppose that I didn't understand you well. If I use this code

\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage[T2A]{fontenc}

\renewcommand{\CYRZ}{Z}

\begin{document}

Z

\end{document}

Than that "Z" is not in cyrillic in pdf. What I am doing wrong?
 
@Cortizol If you want a transliteration, you don't want a cyrillic Z in the output, do you?
@Cortizol Please, can you fully explain your problem? Now I have to lecture, will be back in a couple of hours.
 
1:33 PM
@egreg Okay. Problem is next: can I use english alphabet to write in winedt to provide cyrillic from T2A?
 
@JosephWright if we end up avoiding the clash by updating etex.sty I wouldn't want to complicate the code too much to avoid problems with an old etex.sty, what could you do in that case? (we could for example put etex.sty into base to make sure it got updated)
@Cortizol so you want to write using the latin alphabet and transliterate to cyrillic? Rather than write directly in cyrillic? The original ams cyrillic fonts were designed for that but T2A is more designed for typing cyrillic directly as it doesn't have ligatures to map multiple latin letters to a single cyrillic one.
 
@DavidCarlisle Yes, I would like to do that if that is possible. I would like to do in that way because I write some math text and I need to use every time alt + shift (twice) to switch keyboard from cirillic to english and that is really painfull.
@DavidCarlisle Because when I use math mode I need english so I need to switch keyboard.
 
Is there any template for this presentation?

http://research.microsoft.com/en-us/um/people/senyk/slides/encryptedsearch-full.pdf
 
@Cortizol It's not really possible as unlike the characters above 127 which you can make active and have any definition you like, if you make the latin characters active then they are no longer "letters" so that you can not type commands such as \begin The OT2 font encoding for the wnr10 font did work in this way by placing the cyrillic characters in the ascii positions and having ligatures so that zh ligatured to ж (if I got that right, sorry I can not read cyrillic:-)

Title:          Cloud Cryptography
Author:         Seny Kamara
Creator:        Microsoft® PowerPoint® 2013
Producer:       Microsoft® PowerPoint® 2013
@imVoid Not produced with TeX and friends, I'm afraid. So one has to construct this template from scratch.
 
1:48 PM
@imVoid It's powerpoint so nothing to do with TeX!
oh @PauloCereda just said that:-)
 
@David and @Paulo, thanks for the info..
 
@DavidCarlisle I survived the amount of emails. :)
 
But is there any way to create such a presentation using latex?
 
@imVoid you might have guessed it was powerpoint, given the site it is coming from:-)
 
@DavidCarlisle Also, look at the math in the slides. :)
 
1:50 PM
@DavidCarlisle :D, but the content suggested otherwise
 
@imVoid why? If it had been set in LaTeX the maths would be a lot better
 
@DavidCarlisle Yes, you got it right! :-) I know for OT2, but cyrillic from T2A looks more more prettier for my eyes. Well, what to do, that is life... :(
 
@Cortizol yes the OT2 fonts are really old and hopefully newer fonts are better developed.
@Cortizol sorry I can't help much being English I don't have a lot of practical experience of needing to change keyboard layout.
 
@DavidCarlisle No problem. You helped me a lot. I will see, probably with @egreg, I suppose he knows, is there some big different between this cyrillic physics.ox.ac.uk/Users/bauke/LaTeX/Tips_und_Tricks/cyrillic/… (I found today on professor cite) and cyrillic from T2A.
@DavidCarlisle I mean, there is some difference, you can call me crazy, but when I zoom 500% cyrillic from that PDF (physics.ox.ac....) I can see that letters aren't smooth (mathematical term) enough, like in T2A. I know that human eye can't see when read printed file, but there is problem in my head with that... :)
 
@DavidCarlisle yep.. Im creating a math + business presentation and I would like to create a similar ppt.
@DavidCarlisle Math is best with Latex..
 
2:04 PM
@Cortizol You presumably have pk (bitmap) fonts for the OT2 fonts and type1 (scalable) fonts for T2. Originally all TeX fonts were bitmap. I do not know if the wnr cyrillic was ever converted to type1 format.
@Cortizol seems like they should be available in scalable form my texlive 2014 has :
$ kpsewhich wncyr10.pfb
/usr/local/texlive/2014/texmf-dist/fonts/type1/public/amsfonts/cyrillic/wncyr10.pfb
 
@DavidCarlisle The issue comes about because etex doesn't redefine \newcount, etc. but rather \alloc@
 
@JosephWright yes but the plan was so long as it switched before extended registers were used it shouldn't matter as it's using the same count10-count19 to record where things are. But it seems that isn't quite right
 
@DavidCarlisle Indeed: etex sets registers 260 to 276 on loading whether they are needed or not. That's where the problem comes.
@DavidCarlisle If you load etex with the new allocation code the latter is always used as it redefines \newcount, which etex doesn't
 
2:22 PM
@JosephWright Can't really think about it now, but that shouldn't matter if etex.sty is loaded before those are allocated
 
@DavidCarlisle It doesn't: disaster either way :-)
@DavidCarlisle etex assigns by number to them so they end up as 'junk'
@DavidCarlisle I suspect you are right about dropping 'local' allocations: I might be tempted to go further and simply remove them entirely
 
@JosephWright it should be possible to arrange that if etex.sty is loaded into a new format the allocation system is completely replaced and any existing allocation counts are if necessary copied from count10-19 to count256-266 so it pick up where th ekernel left off
 
@DavidCarlisle If etex is updated to know about \e@alloc, yes
@DavidCarlisle The 'skip 21 counts' will fix Ulrike's issue :-)
 
@JosephWright yes
@JosephWright more or less anything fixes that:-)
@JosephWright but meanwhile I have to worry about C string buffers..
 
@DavidCarlisle Cool :-)
@DavidCarlisle I'm on the train acting as a courier for an instrument part, so I have a rather bitty day!
 
2:27 PM
@JosephWright If we do that then simply saying \let\globcount\newcount in etex.sty for new formats pretty much covers the remainder
 
@DavidCarlisle Yes
@DavidCarlisle Do we need Peter Breitenlohner involved here? CTAN probably will need him to OK a change to etex.sty.
 
@JosephWright yes but I wanted to get agreement on what we want any changes to be before I contacted him. I wrote 90% of the thing anyway so I don't think he'll disagree especially if we point out the unchanged file makes documents hang
 
@DavidCarlisle :-)
 
@Cortizol No. Only with OT2
 
2:55 PM
@egreg Okay :-(

Ah it's been only yesterday, I haven't noticed that
 
@Johannes_B I deleted it
 
3:43 PM
@StefanKottwitz Thanks.
 
yo'
@StefanKottwitz thanks :)
I wonder how could the OP make an edit on a deleted answer.... tex.stackexchange.com/posts/230949/revisions
 
@yo' vulgarize the use of LaTeX templates... that sounds right up @Johannes_B's alley...
 
yo'
@PaulGessler :D
 
@PaulGessler I cannot see deleted answers :-(
 
@Johannes_B "I see dead people."
 
3:53 PM
@StefanKottwitz Oh, this can't be good. ;-)
 
@Johannes_B you know, 6th sense :-)
 
@StefanKottwitz i am just smiling about the help with the equation in this picture question over at LC.
 
@Johannes_B yes, it's "type this equation for me", we'll see if the user understands, sometimes people are a bit naive but not bad
 
@StefanKottwitz Yeah, thats true.
 
4:15 PM
@PaulGessler Btw, have you seen tex.stackexchange.com/questions/230768/…?
 
@Johannes_B now I have. :-D

Hello everybody.
Does somebody know what type the \middle<delim> math atom is in e-TeX? In Knuth TeX \left<delim> makes <delim> a \mathopen atom. What does \middle do to <delim>?
 
Anybody up for answering?

Q: Class Variables

Nicholas HamiltonI am exploring the use of class options, I was under the impression that optional arguments presented at the point of class declaration, were subsequently presented to all packages used thereafter. Can someone explain to me why the following doesn't produce the output I would expect, which is to...

 
5:36 PM
@HenriMenke vvv
TEX's \left delimiter ...\right delimiter produces two delimiters with a
common size adjusted to the height and depth of the enclosed material. In
-TEX this can be generalized by occurrences of \middle delimiter dividing
the enclosed material into segments resulting in a sequence of delimiters with a
common size adjusted to the maximal height and depth of all enclosed segments.
The spacing between a segment and the delimiter to its left or right is as for
TEX's left or right delimiter respectively.
@HenriMenke texdoc etex :-) in short, it's usually the wrong space, you'd normally want it to be more like \mathbin or \mathrel but it isn't
 
@DavidCarlisle Which \muskip does this correspond to?
 
@HenriMenke 0pt
@Johannes_B @Werner answered it in comments so he gets first go:-)
 
@DavidCarlisle Left a note for him.
Guys, gotta go for now. Have to process the template shock. :-)
 
@HenriMenke basically \left(.... \middle| .... \right) is like \left(.... \right|\left| .... \right) except the two middle | are one and the vertical size in both halves is the same. But normally you want the expression close to the leftright brackets but with space added for middle, but that isn't what etex does.
 
Thank you very much for the clarification @DavidCarlisle. Are you coming to TUG2015?
 
5:47 PM
@HenriMenke not sure yet
 
6:19 PM
@HenriMenke My life depends on that info as well. David will give my a ride. We will sing lots of songs during the trip. :)
@wipet: I wanted to know Czech so I could read TeXbook naruby. :(
 
6:38 PM
@DavidCarlisle: do you know Feed The Beast?
 
@PauloCereda I think I saw it but I don't think M has that set of mods
 
@DavidCarlisle hm. I'm tempted to try it.
 
@PauloCereda I could translate of for you
 
@DavidCarlisle ooh <3
 
@PauloCereda into Portuguese
 
6:42 PM
@DavidCarlisle yay!
 
@PauloCereda easy compared to other languages I know: github.com/mathjax/MathJax/issues/474#issuecomment-76739724
 
yo'
@DavidCarlisle lol
 
@DavidCarlisle LOL
 
6:59 PM
@JosephWright so I was checking handover to etex allocation was safe, so what do you think this does in TL2014....
\documentclass{article}

\newcount\zz

\count10=230

\newcount\zz
\newcount\zz
\newcount\zz

\usepackage{etex}

\newcount\zz
\newcount\zz
\newcount\zz


\stop
 
@DavidCarlisle Oops
 
@JosephWright obviously must be Peter's bit
 
@DavidCarlisle Certainly
 
@JosephWright so current plan (ignoring the above for a bit) is simply to suggest changing etex.sty to look like
%% We don't change the LaTeX definitions of \newcount, etc., but the
%% \alloc@ macro doing the actual work is redefined.
%% To ensure working in LateX 2015 release do define \newcount etc
%% with their pre 2015 LaTeX definitions
\def\newcount{\alloc@0\count\countdef\insc@unt}
\def\newdimen{\alloc@1\dimen\dimendef\insc@unt}
\def\newskip{\alloc@2\skip\skipdef\insc@unt}
\def\newmuskip{\alloc@3\muskip\muskipdef\@cclvi}
\def\newbox{\alloc@4\box\chardef\insc@unt}
\def\newhelp#1#2{\newtoks#1#1\expandafter{\csname#2\endcsname}}
 
How do I get that double sign thingy from the TeXbook again? :)
 
7:07 PM
@JosephWright then as far as I can see so long as you load etex before extended registers have been allocated it should all work, in 2014 you can't have allocated extended registers before loading etex anyway so I think that is good enough
@PauloCereda $$\vcenter{\hbox{\dbend\kern1pt\dbend}\vskip 11pt}\;;$$
 
@DavidCarlisle wow
@DavidCarlisle Did you grep that? :)
 
@PauloCereda I usually have texbook.tex in an emacs buffer
@PauloCereda then \def\dbend{{\manual\char127}} % dangerous bend sign
@PauloCereda probably there is a latex package somewhere:-)
 
@DavidCarlisle Seems reasonable
 
@DavidCarlisle Thank you. :)
 
@PauloCereda Thank Richard Stallman
 
7:13 PM
@DavidCarlisle Nope. :)
\documentclass{article}
\usepackage{manfnt}

@DavidCarlisle oh :(
 
@PauloCereda latex packages are for ducks.
 
@DavidCarlisle awwww <3
 
Anyone got an Ello account?
 
7:21 PM
@JosephWright What's that?
 
@PauloCereda Meant to be like Facebook but no ads, etc.
@PauloCereda I'm taking that as a 'no'
 
@JosephWright oh.
@JosephWright First time hearing it.
 
@PauloCereda I picked it up via the PC mag I read
@PauloCereda I asked as I've just had an e-mail entitled:
> March is NSFW Month on Ello!
 
@JosephWright o.O
@JosephWright: Ello is based on monospaced font? :)
 
@PauloCereda Indeed
 
7:25 PM
@JosephWright If you click "I disagree" in the end of the manifesto, you are redirected to Facebook. :)
 
@PauloCereda :-)
@PauloCereda It seems they don't just want a load of swearing :-)
> Help us celebrate NSFW Month on Ello by posting and discussing ideas about free speech, censorship, and why it's important that Internet remain open and free.
 
@JosephWright mail:-)
 
@DavidCarlisle Indeed
@PauloCereda So far, I've not managed to really find anything useful to do with Ello :-)
 
@JosephWright so a good clone of facebook then
 
@DavidCarlisle :-)
 
7:36 PM
@JosephWright :)
 
Hi there people
 
@Danu Hello
 
@DavidCarlisle I was in here two days ago asking about ways of keeping track of changes to a document, I think you answered my question back then.
One of those present in the room suggested I use latexdiff, and it worked very nicely on my test .tex files
 
@JosephWright expandable case changing tex.stackexchange.com/a/230992/1090
 
Now I'm just wondering: What if the document uses a lot of complicated packages? Will latexdiff still be able to generated a markup .tex file?
(I'm asking because the markup file my test documents generated did not have many packages or anything)
 
7:46 PM
@DavidCarlisle What's needed?
 
@Danu I'm sure you can break it (not used it myself) but it has survived for decades and still seems to be the first mentioned tool so it can't be all bad.
 
@Danu Depends on the package, but it tries: I've got a mail to answer about supporting one of my ones
 
@JosephWright You to fix Nicola's package:-)
 
@DavidCarlisle Ah
 
@JosephWright Okay, thanks
 
7:48 PM
@JosephWright was quite tricky to workaround actually the numbering command isn't expandable and has a literal [f] argument that mustn't be uppercased, and the whole thing in a chapter format with MakeUppercase....
 
I'll just give it a shot with some more complicated files then
 
yo'
@DavidCarlisle I wonder who could star that comment if @wipet is not in the room :)
 
@PauloCereda with some ordinal female gender thingy. I'm such a natural linguist.
 
@DavidCarlisle Of course. :)
@SoundsOfSilence: Christian, come back please.
 
8:14 PM
emacs, of course! — David Carlisle 2 mins ago
 
@DavidCarlisle @JosephWright it seems to be working, even though I get this little error every time I run it
Nevertheless, the markup file produced is good (so far)
I'll probably just disregard it if nothing 'bad' happens (I'm no good with computers)

Q: Question about diagrams on latex

VrouvrouPlease how i can write with latex to obtain something like this: Thank you

Oh great, another one of these questions
I know some people like to give users time to learn but I do wonder if a slightly firmer line might be appropriate in this type of case
 
@JosephWright LOL, this looks hilarious
 
@JosephWright \includegraphics{ZgFZM.png} ;-)
 
@Danu Yeah, except there is a tendency for people to answer on the 'the user needs help' grounds. I understand that but I also see that these are really low-value questions.
@PaulGessler Good plan
 
@JosephWright I 'grew up' on Physics, where the policies are quite strict. I like it
 
yo'
Easily. You open the TikZ manual, learn the basics, try to make the diagram yourself, and if you have a specific problem, you edit your question to reflect this one particular specific problem. — yo' 52 secs ago
@PaulGessler that's seriously and officially mean :D
 
8:48 PM
@Danu Yes, like I say it comes down to a community feeling, so I can only follow
 
yo'
@JosephWright you sound like that you don't like our "be nice to newcomers" policy...
 
@yo' No, it's not that
 
yo'
@JosephWright I know
 
@yo' I'm all for being nice but I'm not convinced that people asking these questions are really getting the benefit: they come, they (do) get an answer, they leave
 
yo'
@JosephWright and they never learn anything. That's the problem I have with it. It's not "investing time into them", it's "losing time on them".
 
8:51 PM
@yo' Yes
 
yo'
anyways, now its bout the time to fix my l3keys stuff.
So you say that one of the reasonable ways is to "redefine" the key when it stops being useful?
 
@yo' Yes
@yo' That's really the official approach (I guess I should document it)
 
yo'
@JosephWright Ok, thanks.
 
@yo' BTW, I see this user has had an account for a year
 
yo'
@JosephWright that's why I wasn't over-polite in the comment
 
9:03 PM
@yo' no, suggesting someone use tikz: not polite at all.

@JosephWright shut up.
(without the call to @Joseph of course)
@JosephWright Is there a way how to add more items at once in a _seq?
 
@yo' Not via an official interface, though you can convert from a clist to a seq in one go
 
yo'
@JosephWright and clist has this?
ah yes, it does
I can use _clist then :)
 
@yo' Well a clist is something of a compromise in the first place!
 
yo'
@JosephWright why? (needed to say, I don't really use it)
This seems to be the only line with `clist` in my code: `\seq_set_from_clist:Nn \l_temp_ctuthesis_a_seq { #1 }
`
@Joseph ah, you can do this: \seq_gconcat:NNN \g_aaa_seq \g_aaa_seq \l_bbb_seq

@yo' Comma lists are a sort-of interface level thing, while sequences can contain anything. However, commas lists are convenient!
 
yo'
@JosephWright indeed
however, I seem to use \tl_map_inline:nn { {author}{supervisor}{supervisor-address}{day}{month}{year}{facultynum}{specifica‌​tion-file} } { ... } to do a foreach
 
@JosephWright ltplain.dtx \def\new@mathgroup{\e@alloc\mathgroup\chardef{\count18}\sixt@@n\sixt@@n}
@JosephWright lua and xe tex allow more than 16 fam don't they?
 
@JosephWright both allow 255 it seems
And today's quiz is: what error message do you get from the following (using latex to get the answer is cheating)
@JosephWright ^^
 
9:24 PM
@DavidCarlisle This can’t happen. ;)
 
@HenriMenke actually the test was only applicable to me...
 
@DavidCarlisle Is it really This can’t happen.? Actually I wanted to crack a joke.
 
hello
please
how to write $\Leftarrow $ and $\Rightarrow$ one over the other
please
 
@HenriMenke 'fraid not:-)
 
@Vrouvrou $\overset{\Leftarrow}{\Rightarrow}$ or the other way around, whatever you need.
 
9:27 PM
@Vrouvrou go to detexify.kirelabs.org/classify.html and draw the thing, it will tell you
 
the \Leftarrow is so small
can we do something ?
 
@Vrouvrou Like this?
\documentclass{article}
\usepackage{amsmath}
\begin{document}
$A \genfrac{}{}{0pt}{0}{\Leftarrow}{\Rightarrow} B$
\end{document}
 
there is a big space between the two
 
@Vrouvrou Are you aiming for \Leftrightarrow?
 
yes but one sens is in a case and the other sens is right in a diffrent case
 
9:38 PM
@Vrouvrou I think it is better you take @DavidCarlisle's hint and go to detexify.kirelabs.org/classify.html
 
i don't find this case in the book
 
@HenriMenke or texdoc symbols and search for arrow
 
@DavidCarlisle In the sidebar I read you use TL2015. Will it include a new version of LaTeX?
 
no no i don't find
 
@Vrouvrou Try this:
\documentclass{article}
\usepackage{amsmath}

\newcommand\RLarrow{\mathrel{\begin{smallmatrix}\Rightarrow \\[-0.35ex] \Leftarrow \end{smallmatrix}}}

\begin{document}

\[
A \RLarrow B
\]

\end{document}
 
9:47 PM
@HenriMenke no TL2015 isn't out yet even as pretest, but I'm using the 2015/01/01 latex release over my TL2014 tree.
@HenriMenke hopefully that release will get into the initial TL2015 , not absolutely certain yet.
 
@GonzaloMedina thank you but i want to write something over $\Leftarrow$ and under $\Rightarrow$ can i do this ?
 
@DavidCarlisle So, package authors can soon write \NeedsTeXFormat{LaTeX2e}[2015/01/01]?
 
@DavidCarlisle Where can I obtain it? Perhaps I can contribute to the testing.
 
@Vrouvrou Then try this:
\documentclass{article}
\usepackage{mathtools}

\newcommand\RLarrow[2]{
\mathrel{\begin{smallmatrix}\xRightarrow{#1} \\[-0.3ex] \xLeftarrow[#2]{} \end{smallmatrix}}
}

\begin{document}

\[
A \RLarrow{a}{b} B
\]

\end{document}
 
9:53 PM
@HenriMenke you should be on latex-l list!
@JosephWright oddly enough, that isn't where I got it from.
 
@DavidCarlisle :-)
 
@JosephWright @DavidCarlisle Is there no 'official' location like a git or svn repo?
 
@HenriMenke There's the SVN if you want to build it all yourself
 
@HenriMenke the latex project svn is public as is a mirror to github, but that is a "ctan" release all pakaged up with doc already as pdf ec
 
@DavidCarlisle Only LaTeX3 is mirrored to GitHub
 
9:56 PM
@JosephWright How long does the build take?
 
@HenriMenke About 10 minutes on my system
@HenriMenke You'll need l3build as well
 
@JosephWright you can do the tests in 10 mins? I need a faster machine!
 
@JosephWright Does l3build from TL2014 suffice?
 
@HenriMenke Erm, probably :-)
@HenriMenke Am checking now
@DavidCarlisle Doing time texlua build.lua check: will report shortly
 
@JosephWright Nice, thanks!
 
9:59 PM
@JosephWright hey I just started time texlua build.lua ctan :-)
