Do you know how in some hotels, floor 13 is missing? In this article I got here, obviously the issuse is with numbers 9 and 10 as they are skipped in the equation numbering. :-(

CARNAVAL IS OVER, FINALLY

David Carlisle

10:00 AM

@PauloCereda don't worry it'll come round again next year

Paulo Cereda

@DavidCarlisle oh no

Ulrike Fischer

10:50 AM

@PauloCereda We had to go to one carneval session too (the programm was actually quite good, I have seen much worse) but happily we can't be identified

Paulo Cereda

@UlrikeFischer oooh AWESOME!

David Carlisle

@UlrikeFischer is that @egreg you are with?

egreg

11:05 AM

@DavidCarlisle It's not square

Sebastiano

Good morning to everybody

Thanks a lot lot for your help David

@DavidCarlisle is not quick to write in English and often use the translator. I would like you to answer right away, and I apologize.

daleif

For adding the TL bin to PATH on linux. Does anyone remember the reason why the path additions should be added to both profile and bashrc? It hash to be in at least profile (i'm playing with adding it as a file under /etc/profile.d/, works fine). I think it was something about of one ssh to the PC then profile is not executed. Anyone remember the details?

Christian Hupfer

@DavidCarlisle: No, I spotted @egreg on Sunday afternoon ...

Sebastiano

Hola'''''''''''''''' dear friend, best regards from Sicily

@ChristianHupfer Are you free?

Christian Hupfer

@Sebastiano No, I am bound to this universe (yet)...

Sebastiano

11:21 AM

@ChristianHupfer ahahahaahh, Why my question is negative score?

@ChristianHupfer Is there the possibility to modificate the David's answer only for two fonts tug.org/TUGboat/Articles/tb19-3/tb60kinch.pdf

Christian Hupfer

@Sebastiano Not from me -- Others and me have voted to reduce the negative score, but I think many users regarded it a 'Do it for me' question ...

Sebastiano

@ChristianHupfer it does not matter
Belleek Math Italic (blmi) 10 pt at 600 dots/inch.

Paulo Cereda

@daleif I think there's something about non-interactive sessions, perhaps...

Sebastiano

@PauloCereda Hiiiiiiiiiiiiii paulo my best regardssssssssssssssss

Christian Hupfer

@Sebastiano Really, I am no font expert. I could advise you anything regarding fonts ... 99,9 % of it would be really ~~good~~ bad.

Paulo Cereda

11:25 AM

@Sebastiano Hello! A nice day to you! :)

daleif

@PauloCereda Yes, something like that unix.stackexchange.com/questions/38175/…. I'll see if I can add a line in bashrc that execute my script from the profile, only of this is used as an interactive shell.

Paulo Cereda

@daleif Nice plan. Something along the lines of source /path/to/your/profile

daleif

Just such that the path addition is only set in one place and is only updated in one place.

Sebastiano

@ChristianHupfer Ok Christian.

Christian Hupfer

@Sebastiano There are definitely font experts here, but I am not one of them.

Sebastiano

11:33 AM

@ChristianHupfer But my question is too broad?

Paulo Cereda

@daleif: now that you mentioned it, I remember that in my setup I have TL configured inside /etc/profile.d, which seems to propagate to interactive and noninteractive sessions.

Ulrike Fischer

@DavidCarlisle in texlive 2016 the following outputs "abc" when compiled with xelatex. With plain xetex, xelatex from 2015, pdflatex I get as expected "cba". Do you know what's going on?

\documentclass{article}
\TeXXeTstate=1
\begin{document}
\beginR
abc
\endR
\end{document}

Sebastiano

@UlrikeFischer Hi too you

Best regards to everybody I go to home.

Paulo Cereda

@UlrikeFischer: In other news, I am learning Gregorian chant! It's been very eye opening!

Joseph Wright

11:50 AM

@UlrikeFischer Hmm

@UlrikeFischer I wonder if this has ever worked with OpenType fonts: can you check XeLaTeX 2015 + fontspec?

Ulrike Fischer

@JosephWright @DavidCarlisle: It is the font, when I load fontspec in texlive 2015 it doesn't work either.

Joseph Wright

@UlrikeFischer You've tried another font?

The bit that concerns me is

....\beginR
....\TU/lmr/m/n/10 abc
....\glue 3.33 plus 1.665 minus 1.11
....\endR

Ulrike Fischer

@JosephWright Arial doesn't work either. I think I will have to look what bidi does.

Joseph Wright

@UlrikeFischer My guess this is a general issue with HarfBuzz

@UlrikeFischer Or rather with the link between HarfBuzz, XeTeX and TeX--XeT

\font\OTtenrm="[lmroman10-regular.otf]/OT" %
\OTtenrm
\TeXXeTstate=1
\beginR
abc
\endR
\bye

@DavidCarlisle, @UlrikeFischer ^^^

@DavidCarlisle, @UlrikeFischer One for the XeTeX list I guess

@UlrikeFischer Mail to XeTeX list sent

@UlrikeFischer Probably bidi doesn't 'notice': HarfBuzz will presumably there be working with fonts/codepoints which are RTL so come out correctly

David Carlisle

12:08 PM

@JosephWright just saw that on list, @UlrikeFischer causing trouble again !

Joseph Wright

@DavidCarlisle See also Phil Taylor and my replies

David Carlisle

@JosephWright I started to reply to Phil yesterday and thought there was no point:-)

Joseph Wright

@DavidCarlisle About?

David Carlisle

@JosephWright ah I see, Phil entered this thread, no I meant I thought about explaining latex font handling to Phil (again) (but Ulrike did that for me:-)

Joseph Wright

@DavidCarlisle Which list?

David Carlisle

12:11 PM

@JosephWright er.... oh it was texhax

Joseph Wright

@DavidCarlisle Oh right: I saw the messages but didn't bother with the detail

samcarter

Seems there is a new user species -- the bounty vampire: tex.stackexchange.com/questions/355298/logo-positon-in-beamer/…

Joseph Wright

@samcarter Raised 'higher up': something odd here

Paulo Cereda

@samcarter should I troll him? :)

samcarter

@JosephWright Thanks! The strange thing is, the username first shows up as "Community" and then changes to "user..."

yo'

12:24 PM

@samcarter I replied, but I agree, things are odd there -- the user is non-existent.

samcarter

@PauloCereda Don't wast your precious thesis writing time :)

Paulo Cereda

@samcarter oh

Joseph Wright

@samcarter I've protected the question to avoid low-rep users posting

samcarter

@yo' If it would be Halloween, I would say we have a ghost, but in March? Not really the traditional season for ghost, as far as I know.

yo'

@samcarter could be the carnival thingy

samcarter

12:29 PM

@yo' Oh yes. Now that you mention it, there had been a lot of funny looking people on the telly in the last few days -- could be an explanation :)

yo'

@samcarter :) now excuse me, it's lunchtime for me

Ulrike Fischer

@DavidCarlisle @JosephWright Sorry ;-) But Jonathan explained it quite good. But it can be a bit of a shock, when you don't expect it. Sometimes I do understand why Hans wants to keep the control. But the question arised because I was looking as github.com/lualatex/luaotfload/issues/410 and wondered what is the expected output (with lualatex) of this here:

\documentclass{article}
\begin{document}

ab^^^^0301c ab^^^^0323c

\textdir TRT
ab^^^^0301c ab^^^^0323c

\end{document}

David Carlisle

Khaled again: he's very active around tex last few weeks...

Ulrike Fischer

@DavidCarlisle So I saved you some trouble ;-)

samcarter

@yo' Bon appétit!

yo'

12:43 PM

@samcarter a large bowl of pumpkin soup with ginger, and cheese khachapuri :)

Joseph Wright

1:32 PM

@UlrikeFischer Hans has the situation that he's not putting together two different approaches, certainly, plus the fact that TeX--XeT really isn't very good ...

@UlrikeFischer As Jonathan says, an over-ride might be useful but in the main people expect codepoints to behave based on their intrinsic RTL properties

@UlrikeFischer As the kerning is wrong for LTR text printed RTL, and as this would be an odd case, I guess simply reversing at the macro level is equally appropriate as expecting an over-ride

@UlrikeFischer Conclusion: don't use TeX--XeT, bad things happen (I feel something like a stuck record on this)

@DavidCarlisle ^^^

David Carlisle

@JosephWright true although they also expect to pour in mixed language text and have bidi and hyphenation just work, but they are disappointed, mostly.

Joseph Wright

@DavidCarlisle Sure: language not (necessarily) a property of codepoints, but RTL I think is

David Carlisle

@JosephWright speaking of stuck records, I hope you'll reply to the "color causes vertical offset" beamer issue by a statement that it's not my fault.

Joseph Wright

@DavidCarlisle Most likely

@DavidCarlisle Prod Frank re. Alice I guess ....

David Carlisle

@JosephWright I need to rewrite 1000 year old eps DSC comment parsing code to work around dvipdfm ~~bugs~~ features first:-)

Joseph Wright

1:38 PM

@DavidCarlisle Indeed

@DavidCarlisle Luckily we have a team meeting tomorrow ...

Paulo Cereda

@JosephWright ooh

David Carlisle

It's a pain as Gread@eps is in the package not the def and it has the (now) premature optimisation that it quits if finds a bounding box, and MetaPost puts in is creator line after the bounding box... You don't tell dvipdfm that it is metapost output, it just uses the normal psfile= \special but sees the creator line and interprets the PS directly, while not offsetting by the bounding box coordinates. So the macro layer has to know that comment is in the file :(

egreg

@DavidCarlisle \input boxedeps.tex

David Carlisle

@egreg would that help?

egreg

@DavidCarlisle Maybe; don't you remember it?

David Carlisle

1:46 PM

@egreg looks vaguely familiar but no, not really.

egreg

@DavidCarlisle The first code for including EPS files in a simple way, IIRC

David Carlisle

@egreg speaking of odd image inclusion macros have you ever looked at pinlabel?

egreg

@DavidCarlisle No. :)

David Carlisle

@egreg I hadn't, but there is a question here about it, but I decided not to debug. It loads graphicx then over-rides all the key parsing to be like the original psfig, then changes some other bits.

egreg

@DavidCarlisle Interesting

I have to go to the other side of the town for my lecture. See you later.

Joseph Wright

2:01 PM

@DavidCarlisle Ooops

Ulrike Fischer

@JosephWright If it were for me I wouldn't use right-to-left at all. It confuses me. But in this case I was using xetex only to compare the difference with luatex.

Joseph Wright

@UlrikeFischer :)

David Carlisle

2:12 PM

@Sebastiano don't keep changing the question by editing or in comments. If you want to ask about using belleek (which would be a reasonable question) make a small (but complete test file and ask a new question asking how to set it with belleek fonts rather than newtxmath. The only information I could see anywhere on how to do that is lists.dante.de/pipermail/ctan-ann/2001-October/000084.html

‮@UlrikeFischer ?gnisufnoc si tahw

Ulrike Fischer

@DavidCarlisle That worked. How did you do it?

David Carlisle

@UlrikeFischer your name is written normally so the ping works, the question is written backwards so it can be read in RTL (there is a U+202E in there somewhere:-)

Paulo Cereda

@UlrikeFischer HE IS A WITCH

A very old witch <3

Ulrike Fischer

‮@DavidCarlisle !gnisufnoc yrev

Paulo Cereda

@UlrikeFischer ANOTHER WITCH!

David Carlisle

2:24 PM

@UlrikeFischer now @PauloCereda is surrounded by confusion

Paulo Cereda

@DavidCarlisle Ducks are very naïve :)

Ulrike Fischer

Typing isn't easy with with this setting ;-). I have to use the left arrow to get right and the backspace always deleted the wrong char.

David Carlisle

@PauloCereda ☠🦆

@PauloCereda it is not witchcraft you just have to study the source of all Unicode knowledge:

Collaborative editing can quickly become a textual rap battle fought with increasingly convoluted invocations of U+202a to U+202e.

someone here ?

Paulo Cereda

@Vrouvrou I am not sure, but you are using the wrong class for it. amsart is a class for articles, not books. In order to get a deeper sectioning level, it's highly advisable to use a class that supports it, like book, memoir or KOMA.

Vrouvrou

@PauloCereda thank you

please how to do to get the numeration of the equation like (1.1)

Paulo Cereda

5:19 PM

@Vrouvrou tex.stackexchange.com/questions/241183/… Someone did it, in case you want to stick with amsart. :)

Vrouvrou

no i chang it to book

do you know how to make numerotation of equation like (1.1)

Christian Hupfer

@Vrouvrou \numberwithin{equation}{chapter} should do, but that's the default for book anyway

Paulo Cereda

Good evening to everybody

@DavidCarlisle Meanwhile, I apologize to everyone if I insisted and I insist on my question. Thank you very much in particular @David for your patience towards me.

@DavidCarlisle, @Johannes_B Fonts Times are fine for me but for some type \ partial characters, \ pi, and v I like better than times

Johannes_B

6:33 PM

@Sebastiano Have you seen ransom letters in movies? The ones with letters cut out from different papers? You might be lucky and it will look ok, but chances are high you will get a ransom letter if you decide for (possible more) symbols yourself.

Paulo Cereda

@Johannes_B awww <3

@Johannes_B: in Portuguese, senhor pengüim e senhor pato.

They got rid of umlauts in Portuguese, but I still use them. :)

Johannes_B

@PauloCereda We no speak americano ... wait, portuguese.

Joseph Wright

@PauloCereda That's a diaereses not an umlaut, surely

Paulo Cereda

@Johannes_B ooh

@JosephWright I don't know the name, sorry. :) You are right.

Diaeresis (diacritic)

The diaeresis (UK /daɪˈɪrᵻsᵻs/, US /daɪˈɛrᵻsᵻs/ dy-ERR-i-sis; plural: diaereses), also spelled diæresis or dieresis and also known as the tréma or the umlaut, is a diacritical mark that consists of two dots ( ¨ ) placed over a letter, usually a vowel. When that letter is an i or a j, the diacritic replaces the tittle: ï. The diaeresis and the umlaut are diacritics marking two distinct phonological phenomena. The diaeresis represents the phenomenon also known as diaeresis or hiatus in which a vowel letter is not pronounced as part of a digraph or diphthong. The umlaut (/ˈʊmlaʊt/ UUM-lowt), in contrast...

We know as trema in Portuguese.

Joseph Wright

@PauloCereda Sure: I just went with the normal English name for the concept

Paulo Cereda

@JosephWright You Europeans have a lot of funny accents. :) We have a few. :)

Joseph Wright

7:45 PM

@PauloCereda Well in English we don't have any accents: a diaeresis isn't really an accent as-used in English (as it simply marks that two vowels are pronounced), and it's rarely used in English words (where a hyphen will do)

@PauloCereda I bet @AlanMunn knows more about them :)

Paulo Cereda

@JosephWright oh my, this is getting too much complicated for my humble comprehension. :)

@JosephWright What linguists ever done for us?

David Carlisle

@PauloCereda stick to latex2e 2017/01/01 PL2 that has no usable accents

Joseph Wright

@DavidCarlisle Only in TU

@DavidCarlisle Did you see Chris's mail?

Christian Hupfer

@DavidCarlisle Will shall be happy to incorporate such font features in fontspec

David Carlisle

@egreg Khaled was floating (somewhere) the idea of an external tool that could make a normal otf instance out of one of these for some specified parameters

egreg

@DavidCarlisle Some fun like with big directories with PK files

David Carlisle

@egreg yes but on the other hand the tex setup is experienced in generating fonts on demand so it might just work and might be easier than getting variation support into the engines. we'll see..

egreg

@DavidCarlisle When there will be real fonts using the feature.

David Carlisle

@egreg latin modern math with design size variants back in?

@UlrikeFischer bidi character in the box?

Ulrike Fischer

@DavidCarlisle No ;-). With miktex (and newer harfbuzz) it is ok. With luatex the default font is usable too.
