12:39 AM
@HarishKumar I don't understand the first line (or the code) in your recent answer:-)
 
12:59 AM
@DavidCarlisle Oh my bad, I was trolling you ;-)
 
@HarishKumar of course, I know:-)
 
@DavidCarlisle Hihi :-)
 
1:13 AM
@DavidCarlisle Not going to bed today?
 
@HarishKumar now:-)
@HarishKumar it's an hour later in Italy, so someone's up even later it seems
 
@DavidCarlisle Certainly, Two dons on patrol! :-) @egreg is enjoying his weekend.
@DavidCarlisle @egreg It's time to change shift. Good night to both of you. :-)
 
 
8 hours later…
8:57 AM
Morning all
 
9:07 AM
@JosephWright Hi!
 
@JosephWright Morning
@PauloCereda Morning to you too (I hope)
 
@HarishKumar Hi Harish! Good morning!
 
Let us break the silence!
@PauloCereda Hi How is Sunday?
@PauloCereda For me afternoon! :)
 
@HarishKumar Going. :)
@HarishKumar ooh sorry, I always forget! :)
 
@PauloCereda Going! Should be a great one, I suppose.
 
9:13 AM
@HarishKumar :)
@Harish: ready for v4? :)
 
@PauloCereda Always! :)
 
@HarishKumar ooh you are my hero. :)
 
@PauloCereda /blushing
@PauloCereda When is the release?
 
@HarishKumar ooh that's a tricky question. :) I need to write the manual first. :(
 
@PauloCereda: At which, no one can beat you. You write well!.
 
9:17 AM
@HarishKumar Thanks, but it's not true. :) I fail miserably. :)
Let's see if, for v4, we can have more translations. :)
 
@PauloCereda I can translate to Kannada ;)
 
@HarishKumar ooh! :)
 
Only the problem is, I don't know how to type Kannada in LaTeX! :(
Never tried!
 
@HarishKumar wow, it looks quite complicated. :)
I thought of adding an easter egg in the tool, something like the "duck language", so if you issue:

@PauloCereda Which key gives the egg? ;)
 
9:28 AM
@HarishKumar It's just an idea, I need to select a key for that. :)
 
@PauloCereda Sounds like a good plan :)
 
@HarishKumar Quack! :)
 
@PauloCereda quack quack :)

Q: how to typeset document in indian script

AnilIs there an MWE for typesetting indian scripts (like tamil / kannada). There are couple of examples for devanagari scripts. Can i use the same for other scipts.

 
@HarishKumar See? It's easy. :)
@egreg Alan strikes again. :)
 
9:39 AM
@egreg Yep!. But typing Kannada with english keyboard.... I am out of this job :)
 
9:54 AM
@HarishKumar Buy a Kannada keyboard!
 
@egreg Not a bad idea :)
 
10:15 AM

@PauloCereda I agree seems easy enough ^^^
 
Morning @DavidCarlisle
 
@JosephWright morning,
 
@DavidCarlisle Ergo Latine loqui possumus!
 
@DavidCarlisle You speak fluent google ;)
 
@egreg yes but you are rubbish at it:-)
@HarishKumar how bad was it? (@egreg wasn't very impressed with my Italian earlier)
 
10:22 AM
@DavidCarlisle No mistakes in that phrase. :)
 
@HarishKumar as I expected!
 
@DavidCarlisle :) What's written there? :)
@DavidCarlisle Your Portuguese is also quite good. :)
 
@PauloCereda I speak Kannada fluently.
 
@DavidCarlisle Gallia est omnis divisa in partes tres.
 
@HarishKumar ooh! :)
 
10:25 AM
@PauloCereda Exact translation is "I speak fluent kannada"
 
@egreg I suppose your Latin education never got beyond reciting Caesar's easier passaages
 
@DavidCarlisle I'm a bit rusty.
 
@egreg natural at your age
 
@HarishKumar ah! :)
 
@HarishKumar My Google disagrees
 
10:29 AM
@DavidCarlisle See announcement about new UK-TUG chair
 
@JosephWright no mail yet?
 
@egreg It happens with wizards ;)
 
@DavidCarlisle Only just sent! Kaveh :-)
 
@JosephWright vote with just one nomination I assume?
 
@DavidCarlisle Yup
@DavidCarlisle We don't have a vote with only one name
 
10:32 AM
@JosephWright sure I meant in principle rather than by royal appointment
 
@DavidCarlisle Ah right: yes
@DavidCarlisle You could have volunteered ;-)
 
@JosephWright I've done my stint on the committee (although I don't recall ever volunteering:-)
 
@DavidCarlisle Fair enough
@DavidCarlisle I still have to find someone to do the books :-(
@DavidCarlisle Fair enough
 
10:54 AM
@JosephWright mail arrived
 
@DavidCarlisle Good
@DavidCarlisle I messed up the first version but luckily tried to send it from the wrong account, so it got stopped!
 
11:06 AM
@DavidCarlisle One for you:

Q: Obfuscate Latex command

Filippo BistaffaSay I have a series of commands in my latex source \command1{blabla}, \command2{blublu}, etc... Is there a way to obfuscate these commands, so to maintain their behaviour but hide the actual name?

 
@JosephWright you mean I'm an expert in avoiding site rules about one word answers like "no" ?
 
11:25 AM
@DavidCarlisle LOL
 
@JosephWright OK I answered. with a much more obfuscated answer than @egreg:-)
Oh no, @egreg got the tick. no justice!
 
11:48 AM
@DavidCarlisle He learned basic TeX from me. ;-)
 
@egreg that's why he he needs to come to this site to learn how to do it properly I suppose.
 
@DavidCarlisle :P
 
 
1 hour later…
12:57 PM
@DavidCarlisle ooh that's mean. :)
 
 
1 hour later…
1:59 PM
@PauloCereda true though

Q: Chain of curly arrows above and underneath each other

JamalSI'm trying to draw a chain of arrows going under and above each other, as depicted: The issue isn't labelling the arrows, I can easily do that, but I don't know how to get them to curl, have the arrow head in the middle (ideally, though not necessary), and have one on top of the other. Any hel...

 
2:58 PM
@JamalS If you undelete it we can help
 
@egreg: I managed to resolve the problem, but I can undelete and post an answer later.
 
@JosephWright: Another one...
 
@Werner Taking a look
 
Guys, I think Mark didn't get our invitation. :) Shall we move on? :) I have another candidate in mind. :)
 
@JosephWright: There is a similar/related one which was handled properly.
 
3:07 PM
@Werner isn't that the same 'answer'
 
@JosephWright Yes; one may think that the one (LQ) was handled properly, so the other one (LA) doesn't matter, I guess.
 
@Werner I think this may well be a 'back end' thing
 
The LA was handled first though. Anyway, I'm just bringing "regular things" forward.
 
@Werner Understood
 
3:13 PM
Shall we move on?
 
@DavidCarlisle OK, so make more floats available but leave \newinsert alone?
 
Hi everyone :)
 
@JosephWright yes was thinking leave \newinsert and probably do something like that as a package (could add it to the format but no need really) as there it doesn't check you have used all teh extended registers can ad that but it depends on teh exact form of an extended \newcount etc, how it flags the top of the range
 
@egreg: Undeleted :)
 
@DavidCarlisle Got it
 
3:18 PM
@egreg: What I'm trying to do is draw a diagram of raising and lowering operators acting on eigenstates.
 
@DavidCarlisle So just build in the etex mech for other allocations to the kernel? With the fix for the odd group thing, of course.
 
@cgnieder Hi! Long time no see!
@cfr: Hi! Would you like to be our next TeXtalk interviewee? :)
 
@JosephWright more or less, but I think it should be simpler without the extra commands for global stuff and allocating from the extended range
 
@DavidCarlisle Yes, agree, just the required part
@DavidCarlisle One approach would be just to allocate through but hard-code 255 as a special case, I guess
@DavidCarlisle Mail to team list looks fine to me
 
@JosephWright that was my plan just have \newcount but if it hits \insc@ount just jump past 255 and carry on until you hit the new top which would need to be the float@count from the float allocater so perhaps that does have to be in the format (or at least the allocation number does)
 
3:32 PM
@DavidCarlisle Sounds OK
@DavidCarlisle Will need proper testing
 
@JosephWright speaking of testing, do you understand <number> in this new etex era?
\documentclass{article}

\makeatletter
\mathchardef\float@count=32767

\show\float@count

\count@\numexpr\float@count-1\relax
\mathchardef\float@count=\count@

\show\float@count

\mathchardef\float@count=\numexpr\float@count-1\relax

\show\float@count
why is the expression a valid <number> to assign to a count register but not to a mathchardef?
 
@PauloCereda Hi @Paulo! Quite true... my non-TeX life takes a bit too much time lately...
 
@cgnieder Oh my, I hope everything is fine.
 
@PauloCereda yes, don't worry :)
 
@cgnieder :)
 
3:38 PM
Part of it is a lot of music: at least one gig per week in the last 6 weeks...
 
@cgnieder How nice! Which style?
 
@PauloCereda Depends: I play in a Big Band, in a jazz combo and in a band which plays a blues/rock/funk/pop mix
 
@cgnieder ooh it sounds great! Do you play guitar with them?
 
@PauloCereda only in the last one. In the other two I play bass guitar (a fretless one lately :)
 
@cgnieder ooh awesome! Double bass?
 
3:41 PM
@PauloCereda no :) just a regular jazzbass without frets. (but with fret lines which help a lot...)
 
@cgnieder :) I always wanted to see one of them live. Sadly I only know one or two models (from Fender, I guess), and only in the internet.
 
@DavidCarlisle Reading TeX by Topic, I think we are looking at the difference between a <number>/<8-bit number> and a <15-bit number>: the latter is required by \mathchardef alone
@DavidCarlisle Certainly \mathchardef is different to other stuff
@DavidCarlisle I find a lot of the e-TeX (and later) stuff can only be understood by testing as the docs are unclear at best. See for example the buisness with widows/orphans
 
@JosephWright hm I guess so, I also guess the etex team didn't notice at the time:-) since you can use \count@ and it just makes errors if the number is the wrong form rather than being syntacticaly invalid, \numexpr might have been expected to do the same
 
@DavidCarlisle Yes, I suspect you are right
 
3:56 PM
@PauloCereda first I borrowed one from a friend of mine. It was a fretted one where someone had removed the frets. (He bought it on ebay...)
Now I have one of my own. A cheap one, sadly... instruments do cost a lot more than I can usually afford. But it's a great instrument for its price
 
@cgnieder Very nice. :) I wish I had a fretless one.
@cgnieder: I want this one: caimbe.com.br/violao-tele-six-nylon.php
Two things I like a lot: nylon strings and Telecaster. :)
 
@PauloCereda beautiful!
 
@cgnieder One of the things I found interesting (albeit quite "ugly") is the individual volume for each string.
 
@PauloCereda oh, wow! I'd like to try it. I've never heard of sth like it before. Quite unusual
@PauloCereda this could work for a bass guitar, too: fretnotguitarrepair.com/repair/acoustic-guitar/fretting.php
 
@cgnieder Wow!
 
4:10 PM
@PauloCereda I recently gathered my string instruments (not all but nearly) for a group picture. Not as much as I initially thought. So there's room for more :)
 
@cgnieder Photo please. :)
 
@PauloCereda just a second
 
@cgnieder Amazing collection! Congrats!
 
@PauloCereda you have a collection of your own IIRC... :)
 
@cgnieder It's quite reduced, I guess. :)
 
4:15 PM
@DavidCarlisle \number doesn't work here either, which I think is the shared code path
 
@PauloCereda I only play half of them regularly. But that's normal, I guess...
 
@cgnieder Indeed.
 
@cgnieder How would you describe \ell in german? kalligraphisches ell? (hand)geschriebenes ell?
 
@Johannes_B "Not to be used ell" (translate into German)
 
@egreg Why not using it?
 
4:21 PM
@Johannes_B something like that. I have actually no idea what it is intended to be used for
 
@Johannes_B What's one good reason for?
 
@PauloCereda I'd love to get my hands on this one one day: takamine.com/en-DE/guitars/body/bass/…
 
@cgnieder Wow, it's a beauty! I only knew accoustic guitars from Takamine.
 
@egreg I used it rarely so far. I think i used it onces for litres (as the unit symbol).
 
@JosephWright yep tried that first...
 
4:33 PM
@DavidCarlisle My point is that if \number doesn't work then neither should \numexpr, so this is a 'feature' of TeX :-)
 
@Johannes_B According to the BIPM, the symbol for the liter (litre) is either “l” or “L” (both upright).
 
@egreg Indeed
@egreg \si{\litre} or \si{\liter}
 
@egreg You are right, what did i do? I am really hoping that i was doing something else.
 
@JosephWright stupid language: we should use lua:-)
 
@DavidCarlisle Oh goody: completely unclear Unicode support status
@DavidCarlisle Speaking of which, Chris seems to have gone off onto fonts for some reason
 
4:37 PM
@JosephWright ah OK then C# @egreg would approve of a .NET based TeX, I'm sure.
 
@DavidCarlisle Sure!
@DavidCarlisle It's way easier to plant bugs in this language.
 
@egreg only if you can find a machine on which it runs
 
@PauloCereda I found it by chance a few weeks ago and instantly fell in love :)
 
Sorry
@cgnieder Why do we have fonts and schriften?
 
@Johannes_B I don't know. I believe schriften was the first one but people started tagging with fonts, anyway. We probably need to wait until there's tag aliases. Or create chaos on the active page
 
4:44 PM
@DavidCarlisle That's the mother of all bugs!
 
@cgnieder I just thought some kind of tag-descriptio (like we have here) would be nice.
 
@Johannes_B yes, I have thought that as well before. I'm not sure but there might already be a meta question mentioning this
 
@cgnieder Stefan is not pingable right now. :-(
 
@Johannes_B yes, just found it myself :)
 
@cgnieder To be honest, i forgot about this.
 
5:24 PM
@DavidCarlisle Mono? :)
 
@PauloCereda does it work on a mac (or really work?) I haven't tried it for a while but it wasn't "quite the same" as the real thing back then.
 
@DavidCarlisle It does, but for one or two versions behind the C# spec (I think C# 2.0 or 3.0). The secret is to rely on the default API, but we know no one does that, so it's dommed. :)
 
@PauloCereda seing as the point of c#.net is at least in part to have a relatively sane language with full access to windows API classes, having just the language but without the windows libraries lacks something...
 
@DavidCarlisle Indeed.
 
@PauloCereda so we should port tex, then @egreg, to .net....
 
5:33 PM
@DavidCarlisle :)
I favour Erlang. Let's port TeX to it.
 
@PauloCereda the first part will be the easy part
@PauloCereda or fortran
 
@DavidCarlisle We might need some powerful compiler. /wink wink
 
@TorbjørnT. means thunder bear!
I'll be here all day, folks
But yeah, the open sourcing of .NET will be interesting
 
5:51 PM
@David: I expect you already know by now what to get for Christmas for M. :)
Tumblr is a weird place.
 
6:43 PM
Good maen
 
@ChristianHupfer sup.
 
6:59 PM
@PauloCereda Let's port .NET to TeX.
6
 
@egreg ooh! :)
 
7:17 PM
Hey all!
 
@Iplodman 'ello!
 
How's life? :)
 
Unfair as usual, but good. :)
You?
 
Good. Just thought I'd branch in to other rooms than the usual SO Python room.
 
Cool. :) Have you ever used TeX? :)
 
7:20 PM
I'm a huge user :P
 
ooh. :)
 
I write most, if not all oh them in there, but I'm fairly mediocre.
 
A big fan. :)
 
I'll assume that you're a guru at it, then ;)
 
@Iplodman We all are, don't worry. :)
 
7:21 PM
Actually, let me adjust my statement to I'm a huge user of LaTeX.
 
@Iplodman ooh. :)
@Iplodman: there are lots and lots of gurus here, namely @David and @egreg. They battle every day for upvotes (they broke the 200k barrier a long time ago). :)
 
We have the same over on the Python room. Namely @Kevin and @MartijnPieters
Hm. This has been bugging me for a while now. Would you mind helping me with it?
 
Damn those people who read manuals and documentation. :)
@Iplodman Sure, fire at will.
 
@PauloCereda I think it's more of a case that they're waaaaaaay smarter than the rest of us.
@PauloCereda When I make a TOC with the book class, I get an error: ! Paragraph ended before \@dottedtocline was complete.<to be read again>\par \contentsline {section}{\par. I'm afraid I don't know too much more about why it happens.
 
@Iplodman Sadly, I'm not smarter than the average duck. :)
@Iplodman Have you got rid of all .aux files?
 
7:27 PM
@PauloCereda I'd like to think I am, but certainly not in the realm of Stack Overflow.
@PauloCereda Let me go and see.
So I delete those, and it works. But then it generates anew one and raises the error again. Do I have to delete them every time?
 
@Iplodman Hmmm I think we might need a MWE. Something going to the TOC entry in the .aux file is raising this error.
 
Right, let me gather something up.
Good news! I figured out what line is causing it.
\addcontentsline{toc}{section}{#1, #2}
And, in context:
\newcommand{\poem}[3]{
\addcontentsline{toc}{section}{#1, #2}

{\large \emph{\textbf{#1,} #2}}
\hrulefill
\bigskip\\
#3

\bigskip
}
 
Damn those poets and their TOC breaking code. <3
 
;)
I like to consider my self quite good at poetry, as it goes ;)
 
@Iplodman How nice! Could you share a couple of lines with us? We'd love to see them. :)
 
7:32 PM
Sure c:
They're fairly mediocre too, but I try c:
Be warned: The document it's self has issues.
 
@Iplodman :)
We have some poetry here.
 
@Iplodman: very nice! Congrats!
 
Spaceman isn't finished yet.
Thanks! :)
 
We have a couple of poems, buried in the archives.

Roses are red,
but no flowers are needed,
my love for you is \huge
TeX capacity exceeded.

Roses are red,
blue is my ethernet cable,
TeX is awesome,
so it is longtable

Roses are red,
violets are blue,
math is hard,
ooh a kangaroo!
May 21 '12 at 13:49, by Paulo Cereda
Roses are red,
I lost my key,
new package on queue,
update your tree.
The defining moment of my life. :)
 
7:38 PM
I expect the grand poets to teach me some of their ways c:
 
@Iplodman So @DavidCarlisle is the source of poetry. :)
 
> Roses are symbolic
of my love for you,
all of your beauty,
and sub-par parts too.
 
@Iplodman ooh! :)
 
;)
Never written one like that before.
Is there anything off about this line to you?
\addcontentsline{toc}{section}{#1, #2}
It's the cause of my woes.
 
@Iplodman Check one of the calls.
 
7:43 PM
One of the calls?
Where I call \poem{}?
 
@Iplodman The usage of the macro.
Yes. :)
 
Ah.
Sorry, just checking it mean the same from the other side of programming ;)
All braces are in order, sir!
 
@Iplodman Good! :) Now, check if you have any odd values as parameters. :) Only pure text or any other macro?
 
Ahah!
Fixed it :P
 
Do tell.
 
7:46 PM
Yeah, I had \newpage as a argument ;-;
Silly me.
 
Now on to my next issue: why does CONTENTS appear as a header on every page? Do I have to set a \mainmatter?
 
@Iplodman Because it's hooked with your heading style. You actually don't have proper chapter/sections, you are manually adding things to TOC.
 
True. How can I overwrite the header?
Do I have to use another package?
I can't remember what one it's called.
 
I'm sorry, I'm not well versed in headings. :(
 
7:50 PM
No problem! Gurus can only know so much :D
 
@PauloCereda #Goal
 
@egreg where?
Italy x Croatia?
 
@PauloCereda Italy-Croatia for the European qualifiers
 
@egreg ooh!
@egreg: Oh my, Candreva!
The score wasn't updated here!
 
8:01 PM
@egreg 'Ello!
 
@PauloCereda #:-(
 
@egreg Oh no!
 
Error by Buffon
 
Oh no, it's not updating, it's not updating!
 
@PauloCereda Perišić
@Iplodman Hello!
 
8:07 PM
@egreg I;d ask how your day has been/is/was, but I need to go and do something quickly :)
I'll see you all in a bit!
 
@Iplodman Nice day, thank you!
 
No problem, back soon (Or, as we say in the Python world: "Rhubarb")!
 
cfr
8:35 PM
@PauloCereda Come again?
 
Hello again!
@egreg So, what did you do today? >:)
 
@Iplodman Almost nothing: the weather is horrible. I had some good time on TeX.SX.
 
@egreg One of the best ways to spend a day!
 
@Iplodman Just 275 points. :)
 
@egreg I once got twenty. Am I pro yet? ;)
 
8:45 PM
@Iplodman I got 20 twice and 10 five times (on my first days here), so you're on the good road.
 
Hopefully >:)
But I've got Java to do, so no time for TeX c:
 
@Iplodman Don't drink too much coffee!
 
private int coffee_cons = 12;
System.out.println(coffee_cons);
>>> 12
Although I'm British, I'm not a big tea drinker.
 
@Iplodman Beer?
 
I'm 14 ;)
Slightly illegal! c:
And I don't like alcohol anyway c:
 
8:52 PM
@Iplodman Really? Even younger than Herbert!
@Iplodman Sorry, it's an internal joke! One of the highest rank users declares himself a bit less than his real age on his profile.
 
@egreg Ah ;)
Does that mean I get to be this room's little brother, too? :D
 
@Iplodman Our mascotte. But you shouldn't advertise your age on the Internet.
 
@egreg I know enough to keep me safe. We've learnt about how not to tell someone where you live. Although someone I vaguley knew once accidentally sent me their address.
 
@Iplodman Be careful!
@Iplodman Where do you live? ;-)
