@atticae Hi
 
Can somebody help me out quick, I have trouble with the site being on and off right now? If I define a newenvironment and start off with \small in the definition, will I have to cancel that at the end of the newenvironment declaration so the text after it won't be small? Or will that only apply to the environment anyway?
So something like, \newenvironment{prettytable}{\small}{???}
Do I need something like \endsmall there or is that implied anyway?
 
@atticae No, it will apply only in the environment. But you should end the environment with \par.
 
Hm, okay. I will read up on that. :) Thank you.
Is that necessary even if I wrap something like tabularx in my newenvironment? I would guess that \endtabularx already does something like \par?
 
@atticae You need to be careful with tabularx because it is not really a regular environment: the body of the tabualarx table is actually the argument of a command.
@atticae What exactly are you trying to do?
@atticae I.e., what do you want to achieve?
 
12:33 AM
@AlanMunn I am trying to setup a basic predefined table layout with header column and alternating table rows. Also small text and single line spacing. I have figured it out thanks to some answers on the site, now I wanted to put it in a newenvironment so I don't have to repeat all that code for every table.
It pretty much works now, I just wanted to make sure about the \small part not being ended.
Unless there are some hefty side effects I should know about which are not obvious at first sight, I think I am good.
Thank you for your help :)
Also may I just say you guys on tex.SE really rock and the answers on the site have saved me more than once.
 
@atticae Ok. You're welcome.
@atticae Thanks. I think all of us are proud of both the quality and friendliness of the site.

sometimes I get the feeling I am the only person who uses tex4ht :)
 
 
4 hours later…
8:00 AM
Morning all
 
 
2 hours later…
9:38 AM
@Nasser you are just in wrong timezone :)
 
@atticae tabularx doesn't do \par and anyway the \par would have to be the last thing in your end code, so the group containing the small ended with par
 
10:05 AM
@michal.h21 thanks for the reply. Should I file a bug for this for tex4ht?
 
@JosephWright Morning! :)
LOL
 
10:39 AM
@Nasser you being in the wrong timezone or a bug in titlesec.4ht? :)
 
@michal.h21 I assumed your solution is just a workaround and there is still a bug somewhere? I do not know. If you think it is not a bug, will let it go.
 
@Nasser yes, it is a workaround, there is really a bug in titlesec.4ht
 
@PauloCereda How is l3build review going?
 
@JosephWright Er... going? :)
More seriously, I'm half-way. :)
@Joseph: when you have some free time, Skype me. :)
 
10:59 AM
@PauloCereda OK: just about to make lunch so about an hour-ish
 
@JosephWright No worries. :)
@Joseph: just so we don't pollute the chat. :)
 
@PauloCereda Fine
 
@Nasser I think I have found the issue and possible solution, but I am not sure my solution is correct:
1
A: why package titlesec causes tex4ht to give error when using $[]$ in section title?

michal.h21In titlesec.4ht macro \ttl@straight@i is redefined \let\ttl:straight@i\ttl@straight@i \def\ttl@straight@i#1[#2]#3{% original \ttl@straight@i is saved ad \ttl:straight@i and \ttl@straight@i is redefined to do some additional things. as you can see, [] characters are used as delimiters. Saved or...

12:12 PM
@PauloCereda I got some free time too, want to mail me your Skype contact too? :-)
 
@StefanKottwitz Sure! :)
@Stefan: sent! :) uh-oh, I think I mispelled your name... sorry
 
Hi everybody
I need some help
about pgfgantt
@David Carlisle Need Help in pgfgantt?
 
12:53 PM
Morning everyone
What name does this shape have and how do I make it in TikZ?
 
Cycloid, I guess.
 
That does seem correct
How on earth do I make it in TikZ? "Cycloid" does not exist in the manual.
Prolate cycloid or trochoid is another name
 
1:23 PM
Nevermind, figured it out. Fabricated a vectorfunction and made GeoGebra do the rest. Could've used tikz/pstricks/asymptote but anyhow.
 
1:49 PM
@LaTeXKhan I know absolutely nothing about pgf:-)
 
2:08 PM
@egreg: a legend passed away today. Oberdan Cattani, 95, goalkeeper of Palestra Italia (he played for Palestra years before the team became Palmeiras). :(
 
2:37 PM
@DavidCarlisle Cricket going OK
 
leo
@MarioS.E. twice now :-) June 20 in Italy and June 20 against Italy
That's our Fuente de la Hispanidad
 
3:09 PM
Everyone testing?
 
@JosephWright Alpha!
 
3:42 PM
@leo hahaha, I know, I lived in CR for many years :)
@leo I actually went to UCR, which is very close to that roundabout
 
@DavidCarlisle tools off to CTAN :-)
 
@JosephWright What should we test?
 
@MarioS.E. Well the mail wasn't specific, but registering, logging in, etc., I guess
 
4:04 PM
@JosephWright thanks..
 
4:17 PM
@JosephWright Registering right now.
 
4:41 PM
@DavidCarlisle Got TMS on?
 
@JosephWright no:-) not really in, just passing by
 
@DavidCarlisle :-)
 
Today's live stream commentary is in Arabic.
 
leo
@MarioS.E. cool! I was there too
 
@leo Do you still live there?
 
4:44 PM
@AlanMunn Persian, surely?
 
@JosephWright I don't think so. It's coming via Qatar.
 
@AlanMunn Ah
 
@michal.h21 Thanks for the fix. I sumbitted it and few others I had as minor bugs to tex4ht so they do not get lost and at least there is an official record of them. I put them as minor bugs.
@michal.h21 do you I should submit this as bug also against tex4ht? tex.stackexchange.com/questions/161907/… the problem using siunitx with mathml? as I am not sure what is going on with this one.
 
leo
@MarioS.E. yeah :-)
 
@leo So.. TeX because of... school?
 
leo
4:56 PM
@MarioS.E. yes, I was into math
 
@leo UCR?
 
leo
@MarioS.E. yes
that's what I meant when I said I was there
 
@leo Beautiful country, I really liked living there.
@leo Ohhhh, I thought you were talking about being at Hispanidad
 
leo
@MarioS.E. ha ha, no I was working
yeah, I like a lot, never been out but I like
 
@leo I have a feeling no one was working after the game
 
leo
5:00 PM
@MarioS.E. some of us yes :-)
 
@leo Naturally, "the show must go on" :P
 
leo
@MarioS.E. where are you now? what were you studying at UCR?
 
@leo I currently live in Porto, Portugal
@leo I studied electrical engineering there before coming to Europe
 
leo
@MarioS.E. yes, you had to see. Supermarkets closed, there were lines outside them, and they allowed people to came in as other people came out
@MarioS.E. cool
 
@leo (My dad is half costa rican)
 
leo
5:04 PM
outside math I've found some TeX enthusiast in Electrical Engineering :-)
@MarioS.E. cool :-)
 
@leo from CR? You are the first one I have heard about. This site is mostly Europe and USA. It would be so cool to have more people from other places
 
leo
@MarioS.E. Indeed. Yes from CR
 
@leo I discovered text already living here. It was a shame, my undegrad thesis was written in sigh word!
 
leo
A friend of mine was encouraged by his adviser to write his Proyecto Eléctrico using LaTeX
and then he will write his thesis in LaTeX as well, I hope
@MarioS.E. Yeah it's uncommon. I tried to convince a cousin of mine to write his thesis using LaTeX. He was at Civil Engineering. He refused.
 
@leo I firmly, strongly believe that the hardest part of LaTeX is getting people to use it
 
leo
5:12 PM
I learnt about TeX because of my professors. They all use it. And sometime very early, some of them said that we all should learn. So I did.
Indeed
 
@leo You are A8, A9?
 
leo
Even there in Math School, they ignore a lot of things. Many people just copy and paste and old outdated preamble. They don't know what the lines there are for. They just use it. I learnt a lot from TeX.se
@MarioS.E. he he I'm A7
 
@leo I'm old :(
A4
 
leo
@MarioS.E. I'm pretty old too
@MarioS.E. my cousin was A4 too
 
@leo Are you currently working within the Math area? How is the job market for it?
 
leo
5:18 PM
oh and tried to convince my girlfriend to write her thesis using LaTeX too. She is studying microbiology. So I was teaching her, and she liked and got the basics. Later she refused cuz she had to deliver her thesis in some format imposed by the Colegio de Médicos here which was ofcourse in Word :-(
 
@leo Hahahahahha, it was pretty easy with my wife: I already had a couple of years of "expertise" ahead of her. Of course, all the wisdom came from tex.stackexchange
 
leo
@MarioS.E. no yet. Teaching, but I think it don't think it really counts. The market for pure math is growing here. Of course one can always work with the universities but it will be mostly teaching. Some of my professors complained that it was hard to get funded to do research (they actually said "it is so hard to do research here", so I think it's either that or that they are lazy, but then what do you want a PhD for?). Outside uni, mostly financial institutions hire pure mathematicians.
@MarioS.E. Some tech related companies too. I was so glad that this year in the SIMMAC there were a lot of presentations by private researchers from banks and some (like two or three) from private universities. So it seems it's growing, and I hope so :-)
 
@leo Nice to hear it is opening up
 
leo
5:35 PM
@MarioS.E. Yes, and regarding research there some who do a great job, like José A. Ramírez (who is electrical engineer too), Joseph C. Varilly and some others
 
@leo I haven't had the pleasure to meet any of them
@leo I graduated when most of the EE professors were retiring
 
leo
@MarioS.E. they use to teach Differential Equations for engineering
@MarioS.E. I see. I've heard they have young professors there
 
@Nasser I don't think so, Joseph stated that text mode is set explicitly in siunitx with tex4ht
 
Do ppl working with complicated automata, such as a node is a composite node that contains a small flowgraph as well?
 
@michal.h21 I see. Ok. So we have to wait until siunitx removes this restriction for tex4ht then. Ok. Now I understand what is the issue. It just means I can't use mathml+mathjax with tex4ht since I use SI in math mode, which works ok in tex4ht if I do not use mathml+mathjax.
 
5:49 PM
@leo Yeap, many of them were my classmates hehehehe
 
leo
@MarioS.E. he he
:-)
 
@leo time passes by, things change
 
Poor Iran. Messi saves the day for Argentina.
 
@PauloCereda :(
@PauloCereda I just arrived home; good tour.
 
@egreg You are getting closer to trecentomile ponti :)
 
5:59 PM
@MarioS.E. Expected around 1 August. :)
 
6:14 PM
@egreg Route? :)
 
@PauloCereda I did some new roads; not really famous places. But nice. From Cadore to Carnia, but not by the main road. From S. Vito di Cadore to Sella Ciampigotto (1800m) to Sauris, which is in a secluded valley, where they speak a German dialect (en.wikipedia.org/wiki/Sauris)
 
@egreg ooh Saurano!
 
@PauloCereda And, of course, I had my ice-cream at Busche. :)
 
6:31 PM
@egreg ooh! :)
 
6:57 PM
tabulary uploaded to ctan so @egreg can colour his tables now
@PauloCereda you're the software engineering expert, what version number comes after 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 ?
 
7:15 PM
@DavidCarlisle 0.9a, 0.9a1, …, 0.9a9, 0.9b, …
 
@egreg yes I wondered about that or 1.0 but decided on 0.10 but makeindex didn't sort it as I might have hoped (but I decided it was a feature)
 
@DavidCarlisle Add a new numbering format, so 0.9.1. :) If it's odd it's stable, if it's even it's unstable. Or is the other way around? :)
Now, more seriously: go with 0.10. :)
Or do what I do with arara versions and jump from version 3 to 6. :)
 
evening guys :)
 
@DavidCarlisle In Semantic Versioning 2.0.0 the list would look like 0.8.0, 0.9.0, 0.10.0, 0.11.0: "Each element MUST increase numerically"
 
@HeikoOberdiek yes that's what I did but I wasn't going to make a makeindex style to fix the sorting:-)
this question has been mangled by the OP do you think I should roll back all the edits?
 
7:23 PM
@HeikoOberdiek A user wants to use thumbpdf with arara. I asked him about his workflow. :)
@hugovdberg sup. :)
 
:16203917, @DavidCarlisle: 0.9, 0.91, 0.92, ..., 0.99, 0.991, 0.992, 0.999, ... (see XeTeX). Then the versions can be sorted numerically and alphabetically with the same order.
 
@HeikoOberdiek or I could converge to pi, oh no that would be silly:-)
 
@PauloCereda terribly busy, bachelors thesis due in a week
 
@DavidCarlisle Try Planck. :)
 
@DavidCarlisle Since you are starting with 0.9, you would have to make three major releases (1.0, 2.0, 3.0), before you get near to pi.
 
7:27 PM
@PauloCereda but apart from that I'm good, actually got a job offer for a year immediately after I finish my thesis :D
 
@hugovdberg Yay!
 
@DavidCarlisle Yes, I would rollback to revision 2 and apply the tag fixes of Mico in revision 4, because it rather looks like an accident than intentional.
 
@HeikoOberdiek yes I just did the rollback, I'll look what mico did..
 
@DavidCarlisle I have added .
 
@PauloCereda There are a few other villages where a German dialect is (was) spoken, but have nothing to do with the German spoken in Südtirol, which has a different history: Sappada, that's not far from Sauris, Luserna and the villages in the “valle dei Mocheni”. A Germanic dialect (cimbro) used to be spoken in the “Altopiano di Asiago”, but it's almost lost nowadays. It survives in some villages near Verona, in Lessinia.
 
7:41 PM
@egreg I find those dialects quite interesting. It's very nice to see other languages inside your own domains. :)
 
@PauloCereda thumbpdf is not obsolete with the feature of using own thumbnails other than smaller pages. :-)
 
@HeikoOberdiek ooh. :)
 
@PauloCereda This is not connected with being in a zone near a border, like for Slovenian in the eastern part of Friuli-Venezia Giulia, because it's due to colonizations in the 12th-13th century. Similarly, in Southern Italy we have places where Albanian or Greek is spoken. There is also a place in Calabria where Occitan is spoken: Guardia Piemontese. Some Waldensians went there fleeing from Inquisition.
 
@DavidCarlisle page_compositor "."
 
7:59 PM
@HeikoOberdiek yes I know but it's easier to use the docstrip gglo.ist (although perhaps that should specify that...)
 
@egreg Oh my.
 
@DavidCarlisle In case of gglo.ist it is quite hopeless for version numbers like v1.1a, v2.4c, ...
 
8:16 PM
@PauloCereda Maybe like Japanese in São Paulo.
 
Gooooal!
 
@AlanMunn Which one of the three?
 
@egreg The one that was just scored by Ghana.
 
@AlanMunn Trivia fact: n. 20 of Ghana plays for Juventus.
 
@AlanMunn Thank God @Heiko prefers TeX to Fußball. :)
 
8:26 PM
@egreg They definitely have some good players.
BTW This stream's commentary: European Portuguese.
 
@AlanMunn Pois pois.
 
@PauloCereda :)
 
@AlanMunn O gajo está a chutar? :)
 
@AlanMunn Hey! Klose just went in and scored!
 
8:29 PM
@StefanKottwitz boo! :)
 
@StefanKottwitz This game is not for the faint of heart! :)
 
@AlanMunn And after scoring he tried to hurt himself.
 
@egreg Yeah, that was kind of stupid.
 
@AlanMunn Germany also put in a player with a rather alarming name. ;-)
 
Gooooaallll!
Oh wait, it was a replay.
:)
 
8:32 PM
Klose is really a specialist of being in the right place in those occasions. Just like Gerd Müller and Paolo Rossi.
 
@egreg And Romário. :)
 
@PauloCereda that's worth a penalty kick
 
@StefanKottwitz :)
@egreg: my dad told me that in the past one of the criteria for settling draws was the number of corners. :)
 
@PauloCereda Or “three corners, a penalty”
 
@egreg ooh that's a classic. :)
 
8:45 PM
@PauloCereda Someone must help @David counting version numbers. :-)
7
 
9:25 PM
is there a football match on? I thought the world cup was over?
 
@DavidCarlisle You're late; Germany-Ghana was a draw, 2:2
 
9:41 PM
Good evening, everybody! I striked through the strikes and I'm again in Paris. The final step to the airport is gonna be tomorrow afternoon :)
@PauloCereda Oh a wereduck! :P
 
@tohecz By foot? ;-)
 
9:59 PM
@egreg no. By Roissybus, probably
 
@tohecz Isn't it on strike?
 
@egreg the RER is
@egreg anyways, even in RER, the trains to the airport leave every 30 minutes
 
 
2 hours later…
11:43 PM
@tohecz Where?! :)
 
I just asked in the math chat, but no really elegant solutions over there, but the really smart people are here anyway, so maybe anyone here can help :P
anyone know an efficient algorithm to determine which of n sectors a vector is? the most obvious case being 4 sectors, so simply the quadrants of a circle, but preferably for any number of sectors
I have the feeling there is a very elegant trigonometry trick I'm missing here ;-)
