@michal.h21 Thanks for the answer on image rotation in tex4ht. As I show, it does not work for SVG images. If you need more information to give, I am here.

@JosephWright The format of l3obsolete.txt changed? I guess somebody had a good reason .... There's no comment in the file explaining what or why, though. :(

@cfr dropping svn numbers do you mean?:

commit 1be2cd1659bff8ba581c89119dddafcae10e5848
Author: Joseph Wright <joseph.wright@morningstar2.co.uk>
Date:   Fri Nov 17 19:11:57 2017 +0000

    Drop SVN data from l3obsolete [ci skip]

    The revision numbers are no longer easily accessible, so it does not
    make sense to keep this.

    Outstanding in terms of SVN removal is \GetIdInfo: that is used by
    third-parties so we need to discuss before dropping.

@cfr part of the move to git, mostly I think.

Quack!

@AlanMunn, @barbarabeeton ^^ :)

@UlrikeFischer YES <3

@PauloCereda See ^^^^ some are excited already

@UlrikeFischer Very nice! <3

@UlrikeFischer: I told Frank I am trying to improve my German so I can greet you all. :)

@DavidCarlisle Snow where you are?

@UlrikeFischer I'll go for the same guide I think:)

@JosephWright yes we were all set to go out for the day to watch M play in some hockey competition over in Witney, got a text to say it was cancelled 5 minutes before we left. So I am a lot warmer than I would have been stood on the sidelines:-)

@DavidCarlisle Ooh

@DavidCarlisle Laying here

@barbarabeeton Found it: Advances in Artificial Intelligence by Albrecht Grumme, Fritz Schmelzeisen, and Helmut Helmke, in the May/June issue of The Annals of Improbable Research, I (3) p. 11. Apart from the paper title, authors' names and affiliations, and the running footer, the page is entirely blank.

@HaraldHanche-Olsen quite a long document compared to @PauloCereda's thesis.

@DavidCarlisle oi

@barbarabeeton The same issue has another memorable paper: Apples and Oranges: a Comparison by Scott A. Sandfjord (pp. 2–3) in which the author compares infrared transmission spectra of a Granny Smith Apple and a Sunkist Navel Orange. Never again can one claim that you can't compare apples and oranges!

@DavidCarlisle Don't forget that @PauloCereda knows TeX: He could easily produce a thesis of hundreds of blank pages.

@HaraldHanche-Olsen @DavidCarlisle YES EXACTLY

Wait, what

CIÇA DROPPED MY DUCKS

@PauloCereda Oh no! Did the ducks survive?

@samcarter Thankfully. :)

She (?) probably wanted to play with the ducks :)

@samcarter Yes, she is very naughty. :) She's sleeping near the ducks now. :)

@barbarabeeton, @AlanMunn: I have something to ask you both. Do you believe there is a thin line between update and upgrade? I am asking because some tools I used dropped update in favour of upgrade, so I can only think they are... synonyms (?)... For Fedora and macOS, I use dnf upgrade and brew upgrade, but TeX Live uses tlmgr update. :)

@DavidCarlisle -- well, it certainly has more authors.

@HaraldHanche-Olsen -- i'll have to see if we have that issue squirreled away somewhere. thanks for finding it! (i've forgotten what issue it's in, but air has published a short letter/complaint to the editor from me.)

@PauloCereda -- i think they are different. "upgrade" incorporates the idea of "update", but usually implies more intrusive changes, perhaps even losing (in some features) interoperability.

@barbarabeeton Interesting, it makes a lot of sense!

@PauloCereda I agree with @barbarabeeton. E.g. MacOS 10.11 -> 10.12 = upgrade, but versions within a level are updates. With an update you expect bug fixes/minor improvements. That being said, however, I think that although 'upgrade' can't be used to mean 'update', 'update' is sometimes used when 'upgrade' might be more appropriate.

@AlanMunn Thank you!

@PauloCereda upgrade== up the grade (version number) update== get files with a newer date.

@DavidCarlisle ooh

@DavidCarlisle Folk etymology at its finest. :)

@PauloCereda simples questão de linguística, você não pode esperar que Barbara ou Alan conheçam essas coisas

@AlanMunn of course (although update seems fairly sound, upgrade a bit more dubious)

@DavidCarlisle @AlanMunn: pena que linguística perdeu o trema... :)

@PauloCereda squiggles de pouca conseqüência

@DavidCarlisle Pardon?!

Squiggles :D

@PauloCereda apparently the Portuguese is the same as the English

@DavidCarlisle nope :)

@PauloCereda don't argue with supreme authority!

@DavidCarlisle sorry

@DavidCarlisle The Pope?

@JosephWright ooh The Bishop!

@PauloCereda !!!

@JosephWright We was too late

@DavidCarlisle I don't dare, yesterday seems to be have a bad day...

@mickep ooh an extra vote from me:-)

@DavidCarlisle Oh, many thanks :D

Hello every body, i had some problem to under stand the way of drawing 3D cylinder, any help?

@PauloCereda It's snowy here and black ice forming, everything's slippery, but you probably don't know what it means :-)

any help please?

@MarwaHashem well, currently your question is just an open-ended one-sentence thing. More context would be needed, best if you simply ask a question

i found many ways to draw 3D cylinder with tikz plot ,, but i didn't get it and i want more simple way to get the way from scratch ,,

@MarwaHashem you had an answer here plus links to earlier questions, if you are having an issue with some specific code it is best to show what you tried and what error you got tex.stackexchange.com/questions/411393/…

@yo' Black ice?! Oh my!

@mickep oh no, math! :)

@DavidCarlisle One vote from me too, and one for the green square bloke below. :)

@PauloCereda Pure love! :)

@mickep Quack. :)

@PauloCereda @Johannes_B youtube.com/watch?v=LTECukPlnuk

@AlanMunn oooh one for my playlist

@AlanMunn When ABBA is hit on the head with a french baguette. :D

Dat penguin has moves

@PauloCereda There's so much about this that is amazing.

The maestro looks like George Harrison! :)

@AlanMunn really? I am all ears!

@PauloCereda Don't worry, it's not actually black :D

@yo' ooh

@AlanMunn The lyrics is great!

@yo' Well it kind of is, isn't it? Since it's usually in the context of roads, which are blackish.

Just changed my ringtone

@AlanMunn well, it's transparent. And roads are actually rarely black here, unless you know only 7 basic colours of course :-)

@yo' -- @PauloCereda may not know what it means, but i sure do. take care.

@barbarabeeton don' worry

@barbarabeeton oh

good evening to everybody

hi paulo, hi yo, hi barbara

@Sebastiano Ciao!

@egreg, @PauloCereda, @yo', @CarLaTeX, @ChristianHupfer Why into my question tex.stackexchange.com/questions/411095/… there is a downvote? Ehat is the problem for my question?

@Sebastiano I don't think there's any issue with the question itself.

@Sebastiano Me neither, I am with @yo'

@yo' @paulo Why there is then a downvote? I not see any comment for a downvote.

@Sebastiano I recommend ignoring downvotes without a comment.

@Sebastiano I commented.

@Sebastiano I am sorry, I really don't know what happened. Don't get too upset with this, please.

@TeXnician Ciao e benvenuto

@yo' and I upvoted. :)

@Sebastiano Good evening.

@PauloCereda I saw :-)

@yo' quack. :)

@PauloCereda you're some transparent duck :-)

@TeXnician I'm using the google traslate but i put my reply in italian language. excuse me very much

@Sebastiano actually it was one of your better questions, clear text and clear example.

@PauloCereda ok. thanks lot to the my friends

@DavidCarlisle Hi david. Thanks a lot again for you compliments.

I hope, in the future, to write clear questions. But I not undestood the downvote.

One hour later and I still listening to that penguin song!

Good evening to everybody. Hi and good chat

@Sebastiano Ciao, a presto!

@Sebastiano -- i don't see any cause for a downvote. but i do have one problem with the question. mtpro2 is a commercial font/package, and the real place that the question needs to be asked is at the source. that would probably best be done by someone who is using the full licensed version, who would have more influence. but i don't think i can help with that.

@Sebastiano It's good, in my opinion. I upvoted it :):):)

@barbarabeeton Any insight into this?

@yo' -- i like your answer. the only strong argument i've heard for numbering all equations is that someone else might want to refer to one you didn't reference explicitly. and the author doesn't necessarily know what that might be ahead of time. (a referee might have a suggestion, if paper is submitted for publication.) definitely, if something is displayed only because it doesn't flow properly in line, no number.

@barbarabeeton good point!

@Sebastiano I have no idea. The downvote isn't by me.

@yo' black!50 then. ;)

@DavidCarlisle Does that fix the issue? I don't think so.

@DavidCarlisle In the current version of iflang.sty in TeX Live the date is 2016/05/16

@egreg ? I just copied your code?

@egreg is this not what you meant? github.com/ho-tex/oberdiek/blob/master/iflang.dtx#L494

@DavidCarlisle I found the right commit, thanks. Probably also the documentation needs some fixes.

@egreg % Package \xpackage{iflang} looks for \cs{uselanguage} (defined in I guess i should change this

@egreg yes sorry I had a following commit fixing a date usage. The versioning style in the whole suite of packages is "interesting" with the dates and version numbers appearing in multiple places with consistency checks making sure they are all consistent. When I inherited this I wrote some emacs lisp to update things but I hadn't accounted for a \RequirePackage using a matching date and getting updated "by accident"....

@DavidCarlisle Yes, that's the part to change. Like Heiko, I'd prefer a user level macro rather than an internal, but neither \uselanguage nor \addlanguage is good.

@PauloCereda And @DavidCarlisle kindly provided the Finnish translation for this version. youtu.be/h1yd6dF8g_A

Anyone watching Snooker Masters final

@yo' on in the background

Does anyone have experience with perltex?

@AGoldMan I would guess no, given the tiny number of questions on it, and the ones we do have tend not to have answers.

@DavidCarlisle who's your fav?

@yo' ray reardon

@DavidCarlisle who? ah ok. I meant in the finals, but it's over now any way :-)

@DavidCarlisle Oooh

@yo' google:-)

@yo' My money is on Mark Allen

@DavidCarlisle really? Well, I love that guy! I'm actually happy he won :-)

@yo' I don't think the bookies take real bets after the result is announced

@DavidCarlisle :)

@AlanMunn that's funny, I thought the crowd here likes perl

we're like, the only ones left

@AGoldMan I think for interfacing with TeX, people mainly use luatex and therefore Lua. I guess biber is written in perl, though.

latexmk is also in perl

I just don't wanna learn lua if I already am comfortable with perl

and I use xetex and don't want to rewrite my whole library

@AGoldMan Depending on what parts of xetex you use, it may work just as well with luatex.

@AlanMunn I use a lot of bidi stuff

which I'm under the impression is reversed in luatex

which makes more sense, but is a hassle

@AGoldMan but I think perltex is based on classic 8bit tex isn't it? so moving to that from xetex is a bigger change than moving to luatex (or just calling perl via shell-escape)

@DavidCarlisle perltex is tex-engine agnostic

@AGoldMan Then you're doomed. :) (At least with luatex for the moment.)

and offers more than just shell escape would

@AGoldMan ah is it, I only briefly looked really.

@DavidCarlisle well, i started using it

and it's great

I just don't know how much I can get perl and tex to talk to each other

but I'll experiment I guess

I thought perl and tex go hand in hand, being free form and all

and also jazz

at least for me

luatex is completely different really in that lua is built in to the engine and accessed via callbacks so you can (for example) replace tex's line breaking code by a function written in lua. I don't think perltex lets you interface to the tex internals in that way at all does it?

@DavidCarlisle totally not. I just wanted to know if you could nest calls to perl

all it does is allow you to save perl code in a tex macro, and it'll \edef the arguments passed to perl

which is incredibly convenient

mainly because I think latex3 macro names are too long

@AGoldMan \let\z:nn=\some_long_name_that_joseph_used:nn makes them shorter

i mean map {foo} @bar is much shorter than \seq_map_inline {\l_long_name} {bar}

good night to all

@AGoldMan night

@karlkoeller Congratulations for your 100K!
