Q: How to add a particular object to an `ocg` list

This is an addendum of a previous question: How to put a box and use columns to separate arrows. Please consider this MWE (adapted from a nice answer of that question): \documentclass{article} \usepackage[margin=0in,footskip=0in]{geometry} \usepackage[english]{babel} \usepackage[utf8]{inputenc}...

@marmot @AlexG ^^^^^^ a new question to you! If you feel that it is not clear please feel free to notice me

marmot

01:06

@manooooh I wrote something. Can you please tell me if it does what you want it to do? (Sorry, the question is not 100% clear to me. Before trying to make it more elegant I want to make sure that it does what it should.)

Henri Menke

@marmot I have disabled the issue tracker for PGF on SourceForge. At least I think I did. Can you quickly check whether you can still create tickets? (Please don't create one, I'm migrating right now)

@marmot Just check whether the option is still there and if it comes up when you click it.

marmot

@HenriMenke Hi, I never really understood how the SourceForge really works, which is why I didn't really start to add the relevant libraries. Sorry about that! (So among all users here I am the last one who can say anything about SourceForge. But I will try hard to better with gitlab.)

manooooh

@marmot thanks for your interest! You have made a big progress, but now we have two subjects with one color arrow. Look at the checkboxes, they are only two

marmot

@manooooh Yes, because I thought that's what you want. So you want a new, independent color and arrow?

manooooh

@marmot yes. You only need to be able to find out how can we set to visible/invisible the 3rd arrow, just see the last image of the question

Oh, and I do not know why I am getting a \overfull hbox message. It says it is due to \parbox but I am not sure why it happens :/

@egreg haha, the problem is that the student should know what is a vector, but in my university complex numbers and real numbers are studied in different subjects, so the teacher of Algebra and the teacher of Complex numbers are different. However, you should share with me that a vector is an oriented segment, but I will ask to my new teacher why a complex number is not a vector (something related to sqrt(-1), I do not remember what he said)

marmot

01:29

@manooooh OK, got it and updated it. now there are 3 check boxes, each of which made an arrow appear or disappear. This is much simpler than what I thought you want to do: I thought you want to loop over all easy connections but add a complicated connection to one of the groups. Notice that one can make this more elegant. In any case, this is now all very involved and a typo at the wrong place will make everything collapse. (When you asked the first questions I did not know where the journey ...

... will go. If I had known, I probably would have suggested something else (or, even simpler, just ignored the question ;-) ;-)

manooooh

@marmot probably the culprit was me, since we have not discussed with images and that helps a lot. Now I must leave, but your answer is useful if we have more than one isolated arrow? For example now I want to join (2) and (4), and (0) and (8)

marmot

@manooooh Put them all in the scope \begin{scope}[ocg={name={Arrow<X>},ref=myArrow<X>,status=visible}] the same X.

manooooh

@marmot ok, I will test it then. Thanks!

marmot

@manooooh One can definitely make it much smoother or much more elegant. (I also think to have found an issue with tikz here...)

PGF/TikZ has now officially migrated to GitHub. github.com/pgf-tikz/pgf

Henri Menke

04:59

Oh, and sorry to everyone who had starred the old repository. I have deleted it, so you have to star again.

I'm not yet sure whether I should migrate the feature requests as well.

CarLaTeX

@HenriMenke There are 2 feature requests of mine on that list. Let me know if I have to reopen them.

Henri Menke

@CarLaTeX I'll decide tomorrow what to do because there are also some nonsense requests, like sourceforge.net/p/pgf/feature-requests/94

CarLaTeX

@HenriMenke ok :)

David Carlisle

06:57

@JosephWright "Indicative votes" whatever gave you the idea?:-)

08:28

@manooooh OK, then velocity and acceleration are not vectors, according to your definition.

David Purton

@marmot Given, my timezone compared with most of the rest of the world, I'm usually sleeping ;). Didn't you know koalas spend 18–22 hours a day asleep?

Henri Menke

08:58

@JosephWright I would like to give you push access to the new PGF/TikZ GitHub repository. First of all, this will avoid the previous situation that no one has access to the upstream anymore and it also will secure that the interests of the LaTeX team are represented in the most important package there is. Are you okay with this?

Joseph Wright

@HenriMenke Sure

Paulo Cereda

@HenriMenke ooh

@JosephWright ooh

Henri Menke

@DavidCarlisle Same for you vvvvvvvv

CarLaTeX

@HenriMenke I'm not sure @DavidCarlisle will agree on "the most important package" :)

Henri Menke

@CarLaTeX It's definitely the one with the most users.

CarLaTeX

09:04

@HenriMenke Yes, I said David would not agree :)

Joseph Wright

@HenriMenke Yup

David Purton

@HenriMenke Issue #29 didn't get migrated across, for some reason? Github has 524 issues and SourceForge has 525 issues, and this is the one that is missing. I only noticed because I have a vested interested in CMYK shadings :).

Henri Menke

@DavidPurton You are referring to Feature Request #29 (which I have not yet migrated but probably will). There is one fewer issue on GitHub than on SF because Bug #192 doesn't exist on SF.

Joseph Wright

@HenriMenke If my l3draw experiments bring up any issues in pgf, I'll log PRs

@HenriMenke Strange!

@JosephWright The missing bug crashed my migration script the first time.

David Purton

09:08

@HenriMenke Ah. Fair enough.

Joseph Wright

@HenriMenke I'll bet

Skillmon

Do you guys think \long\protected\newdef\foo#1{#1} or \newdef[\long\protected]\foo#1{#1} is better syntax?

Joseph Wright

@HenriMenke Did you end up doing it in two parts? First move the issues before the gap, manually create a dummy issue, then do the second part?

@Skillmon Huh?

Henri Menke

@JosephWright vvvvv

if bug == 192:
    continue

Joseph Wright

@HenriMenke :)

Skillmon

09:10

@JosephWright just in general, if I created a \def variant that does test whether the macro is already defined, which variant should be used?

Joseph Wright

@Skillmon You know that if you want to use the primitive form you'll need to keep everything expandable in \newdef?

Henri Menke

@Skillmon \newcommand

Skillmon

@HenriMenke that's not an option.

@JosephWright it is.

Joseph Wright

@Skillmon Depends really what your aim is .. I mean that is basically \newrobustcmd from etoolbox anyway

Henri Menke

@Skillmon That literally does what you are asking for. It tests whether the command exists before defining it.

David Carlisle

09:12

@CarLaTeX expect a standard pineapple pizza node shape coming up....

2

Joseph Wright

@Skillmon If the aim is 'plain like' drop in, then use prefixes. If it's meant to be more LaTeX-like, the second form seems better but really as @HenriMenke says that's what \newcommand is for ...

Skillmon

@HenriMenke but it is a) slow, b) can not define delimited arguments.

Joseph Wright

@Skillmon \cs_new_protected:Npn ;)

@Skillmon 'Slow' is a relative term .. if you have a really tight loop then yes, but in that case 'reserve' the name outside the loop

Skillmon

@JosephWright I know, but say I don't want it to depend on expl3 because it's huge?

CarLaTeX

David Carlisle

09:13

@HenriMenke thanks

Henri Menke

@DavidCarlisle I take that as a yes.

Joseph Wright

@Skillmon It's up yo you of course: various people don't like the idea of a large library, but the load time is today pretty small and really the performance hit (hash table impact) is tiny. Like I said, if that's not an option I'd use \newrobustcmd or some variant of that idea

CarLaTeX

@DavidCarlisle Recent LGBT's protest against a ultra-catholic congress ^^^

Joseph Wright

@Skillmon If you want really fast and light, you probably want to stick to prefixes ... as you avoid having to parse for an optional argument

Henri Menke

@JosephWright Is there a particular reason you don't want to bake expl3 into the LaTeX2e format?

David Carlisle

09:16

@HenriMenke don't ask him tricky questions:-)

Joseph Wright

@Skillmon I take it you have something like

\long\def\newdef#1{%
  \ifdefined#1%
    \ERROR % Or use an undefined csname as is done for expl3
  \fi
  \def#1%
}

Skillmon

@JosephWright I really came to dislike \newcommand for it's limiting nature of not allowing delimited arguments.

Joseph Wright

@HenriMenke We are working on it! The probably at present is there are very different stability rules for the two. I'm trying (slowly) to move everything to 'stable' status in l3kernel: perhaps by the end of the year

@Skillmon It's meant for document commands in LaTeX style: the restriction is not unreasonable there

@HenriMenke We've already pushed load time to deal with issues in LuaTeX. Baking into the format is doable (but will need some test system updates). It's a policy not a technical issue. As @DavidCarlisle says, it's non-trivial.

Skillmon

@JosephWright mine is a bit larger \long\def\newdef#1#2#{\newdef@#1{#2}} and \long\def\newdef@#1#2#3{\newdef@ifdefinable{\def#1#2{#3}}{\ERROR}} and \def\newdef@ifdefinable#1{\ifdefined#1\ifx\relax#1\expandafter\@gobble\fi\expandafter\@thirdofthree\fi\@firstoftwo.

Henri Menke

@JosephWright Why \ERROR instead of \errmessage?

Skillmon

09:21

@HenriMenke \ERROR is a placeholder for something that throws the error.

@JosephWright that \@gobble should be \@gobbletwo... Also in the real code I don't use \expandafter but some \long\def\newdef@fiBn\fi#1{\fi} and similar, cause those are faster.

@JosephWright I know and I understand that, and it makes sense for users, but not for packages. And if you still want to test for compatibility (e.g. test whether the macros are not yet defined) the workaround of \@ifdefinable\foo{\def\foo{...}} is again, slow.

Joseph Wright

@HenriMenke To work with a prefix, you need everything to stay expandable. I use \ERROR as a place-holder (it's undefined): for L3 we use a trick to get at least some text that reads nicely

Skillmon

@JosephWright Depends on what you do. If you want to discard the new definition in case it is already defined, you might as well use something unexpandable in \ERROR.

Henri Menke

@JosephWright In LuaTeX you could use \directlua{tex.error(...)}. That is fully expandable and gives a proper TeX error message.

Joseph Wright

@Skillmon Like I say \cs_new_protected:Npn. Really, that's what having a library is about. But I know that not everyone is keen.

@HenriMenke Yeah, true, but that means going LuaTeX-only or having behaviour vary

Skillmon

@JosephWright that enforces some huge overhead for a tiny package...

Joseph Wright

09:29

@Skillmon As I said, it really does depend on your view on libraries. As already mentioned, baking into the LaTeX format is on the list of 'to do' things.

Skillmon

@HenriMenke something else. If I want to publish some code that is similar to pgfmoduleparser.code.tex (and inspired by it) is there any restriction like not publishing under the name pgf...?

Joseph Wright

@Skillmon What overhead are you thinking? Just defining 'lots of csnames' isn't actually an issue on a modern system. But I know that this may well be a philosophical rather than technical objection: there are some well-known people who simply don't like the idea.

Ulrike Fischer

@Skillmon well at first expl3 will be in the format anyway in the not to far away future, and at second I don't have many document today which don't load expl3, so using it doesn't enlarge the loading time.

Skillmon

@UlrikeFischer yes, I guess you're right. Perhaps I'm too performance concerned (damn that l3benchmark package :)

Anyway, heading for lunch. See you later.

Joseph Wright

@Skillmon Er no, because you get the prefix error first:

\long\def\newdef#1{%
  \ifdefined#1%
    \errmessage{} % Or use an undefined csname as is done for expl3
  \fi
  \def#1%
}
\long\newdef\newdef{foo}

! You can't use a prefix with `\errmessage'.
<to be read again>
\errmessage
l.7 \long\newdef\newdef
{foo}

Henri Menke

09:32

@Skillmon It's surely not advisable to publish under pgf... as there must be no two files with the same name in the texmf tree.

Joseph Wright

@HenriMenke Yeah: I think like l3... for us, I'd 'suggest' people don't call things pgf...

Henri Menke

@Skillmon If it extends PGF, why not contribute it to upstream and have it in the next release version?

Joseph Wright

@Skillmon For me, loading expl3 in a pdfLaTeX run is simply not noticeable at all. There is a slight hit in LuaTeX/XeTeX, as we have Unicode data to load. But it's all tiny.

@Skillmon In the end, it comes down to how many things your re-code yourself. The clever people on the team (David C, Bruno, Morten, Alain in the past, ...) have come up with lots of tricks that I'd not find myself. So all I'd do in avoiding loading expl3 is re-code a lot of stuff by hand. But it depends what tools you require.

David Purton

@JosephWright Can packages be removed from CTAN? As some guilty of not following your suggestion, hopefully pgf-cmykshadings will be included in the main pgf packages in the future. But then what? my package becomes useless. But I notice there are lots of packages left in CTAN (and the distros) that now should not be used.

Ulrike Fischer

@DavidPurton if it is your package you can always request that it is removed or moved to obsolete or renamed or whatever. Simply write to ctan.

Joseph Wright

09:45

@DavidPurton Packages can be removed it the uploader asks (very early in my development 'career' I wrote something that I withdrew). Generally, once you have users, this tends to be avoided, although a rename might be OK (for example, we recently asked someone to avoid l3... and they came up with a new name)

Skillmon

10:09

@JosephWright oh, you're right.

@HenriMenke ok, what are the requirements for that?

Sebastiano

11:35

@Kurt Thank you very much for yesterday.

Hi to everybody.

Sigur

Hello friends. Where can I find info on how to make the \cite{} prints in bold? I'm using biber. I'd like to obtain [Mil55], for example.

Sebastiano

@Sigur Hi :-)

Sigur

I'm checking the biblatex texdoc but it is too huge and no success yet. I suppose some keys on preamble should work.

Sebastiano

@JouleV How are you?

Sigur

@Sebastiano, hi.

Sebastiano

11:45

@AlexG Good morning....but @marmot the wizard where is? :-)

@AlanMunn Good morning

@CarLaTeX How long are the festivities? :-)

@manooooh Good morning....do you like \overline, \vec or \vv by esevect?:-)

@TeXnician Good morning from Sicily and welcome into chat.

@HaraldHanche-Olsen Good morning. My cervical is a little less painful. But maybe I have a fever and I have chills. I came back from work but my feet are frozen.

@PauloCereda Good morning also to you.

AlexG

@Sebastiano Still in bed, perhaps?

Sebastiano

@AlexG If I stay home it's worse; better to work with students. And then I should go to the supermarket to go shopping. :-(

@daleif Hi and good morning.

daleif

@Sebastiano hi

samcarter

@Sigur You could try something like

\renewbibmacro*{cite}{%
	\bfseries%
  \printtext[bibhyperref]{%
    \printfield{labelprefix}%
    \printfield{labelalpha}%
    \printfield{extraalpha}%
    \ifbool{bbx:subentry}
      {\printfield{entrysetcount}}
      {}}}

Sebastiano

@AlexG I'm sitting in front of my laptop. But I also have a cough. There's the flu around here in Sicily.

Sigur

11:53

@samcarter, perfect!!

AlexG

@Sebastiano Here as well. Thus, you are not alone.

Sigur

Thanks so much. In your opinion, should the brackets be bold also? I think not. What do you think?

samcarter

@Sigur You're welcome!

Sebastiano

@AlexG Here the weather changes all the time. First cold, then warm to 24 degrees, now we are at 16 and it should rain on Thursday and Friday.

@Skillmon @UlrikeFischer Hi, and welcome

Ulrike Fischer

@Sigur I would never, really never print a citation in bold. Do you really think that this it the most important piece in your sentence and should stick out like this?

AlexG

11:57

@Sebastiano here it's 15 deg, almost as warm as in Sicily! Cielo azzurro.

Sigur

@UlrikeFischer, thanks for attention. Since I'm not going to print the document in color, the blue color for citations was changed to black, so I'm thinking to make it bold to highlight.

Sebastiano

@AlexG Ah but are you italian? :-)

AlexG

no. tedesco.

Sigur

@UlrikeFischer, I agree that if there are many citations in the same page, it could be disturbing.

Sebastiano

@AlexG "cielo azzurro" perfect!

Ulrike Fischer

12:00

@Sigur even with one citation it is disturbing. Why should my first glance at the page attract my eye to a citation?

samcarter

@Sigur I would not replace blue colour for links with bold in print. The blue colour has the purpose to make the user aware that one can click on it which won't work in the printed version, so no reason to make the citations special

Ulrike Fischer

Finally I'm in the club:

JouleV

@Sebastiano Hi.

Sebastiano

@UlrikeFischer excuse me, but why is there a duck?

Skillmon

@UlrikeFischer I don't have even one silver tag badge.

Sigur

12:01

@samcarter, @UlrikeFischer, so I'll follow your advice and keep them in normal font, only replacing blue to black, otherwise the printed version will be gray.

Ulrike Fischer

@Sebastiano I exchanged the pictures. All my badges show as ducks.

Skillmon

@Sebastiano because she overwrote the CSS of TeX.SX

Sigur

But it was nice to learn how to change that format. Thanks again.

Sebastiano

@Skillmon @UlrikeFischer As we say on our side when we don't understand: for me it's Arabic :-) without offence to anyone.

I'm gonna go get some rest. A hug to all of you. Very cordial greetings.

CarLaTeX

@Sebastiano Which festivities?

Paulo Cereda

12:13

@AlexG really! Das ist sehr cool! :) I thought you were an English bloke!

Skillmon

@Sebastiano For us Germans it's Spanish, or we say: Ich versteh nur Bahnhof. Translated: I only understand train station.

CarLaTeX

@Skillmon Oooh, interesting!

Sigur

12:27

What is the newest biber version? I got here This is Biber 2.12. I'm using TeXlive 2018.

But from here https://tex.stackexchange.com/a/273906/14757
it sounds that there are new versions.

daleif

@Sigur erh, 2.12 » 2.2

Sigur

@daleif, sorry, are you saying that 2.12 means 2.2?

AlexG

@PauloCereda Olá, bom dia!

Skillmon

@Sigur no, just 12>2.

daleif

@Sigur no that 2.12 is much newer than 2.2

Sigur

12:31

@daleif, ohhhhhh

@daleif, I'm reading too much in alphabetical order...

LOL

@daleif, it means that I need vacation as soon as possible.

Skillmon

@PauloCereda which kind of bloke is he?

AlexG

@CarLaTeX The ulta-catholic conference :)

CarLaTeX

@AlexG Have you heard about it? There was a big echo on mass media here :)

AlexG

@CarLaTeX No, I learned about it from your comment.

CarLaTeX

@AlexG :)

Paulo Cereda

12:40

@Skillmon a gentle German bloke. :)

@AlexG bom dia!

AlexG

@PauloCereda Obrigado pelo complimente!

Paulo Cereda

@AlexG muito bem! O termo é cumprimento. :)

AlexG

Esta bem, Nao sabia.

Sigur

@AlexG, @PauloCereda, cumprimento \neq comprimento

lol

Paulo Cereda

@Sigur lembrei de quadrilha. :)

Ooh typical food

AlexG

12:48

@Sigur Um cumprimento nao se da para comer.

Sigur

@AlexG, nem um comprimento, a não ser que seja um lanche de metro (não metrô)

I have to go, I have classes. Regards.

AlexG

Agora tenho que ver o que significa 'comprimente'.

Paulo Cereda

@AlexG There is a typical dance in the countryside region during the festivities of saints Peter, Anthony and John, in June. This dance is called quadrilha and has a set of instructions said out loud to the participants. One of them is cumprimento, as you need to compliment your pair. (ctd)

@AlexG measurement. :)

AlexG

@PauloCereda Thanks! Meu portugues tornou-se um poco ferrugente.

Paulo Cereda

(ctd) in these festivities, there's a lot of typical food involved, specially made from corn. It's delicious! Hence my wacky indirect reference.

@AlexG it's surely way better than my German. :)

@AlexG comprimento can also be roughly understood as width.

AlexG

12:55

@PauloCereda Ah, interesting! And which is the more precise term for 'width'?

@PauloCereda Btw, I remember that 'cumprimentar' means say-good-day to somebody?

Paulo Cereda

@AlexG I would favour largura. :)

@AlexG yes, it's the act! You are absolutely correct!

AlexG

@PauloCereda Almost the same as in french.

Paulo Cereda

@AlexG ooh

AlexG

@PauloCereda Sim: 'largeur' (f.)

Paulo Cereda

@AlexG ah interesting!

morbusg

13:08

Hey!

AlexG

@PauloCereda Btw June is the most delightful month in the year, here. Lots of festivities. I am looking forward to it (still 2 months to wait).

morbusg

hey uhmm I was reading the meta moderation question today, and was wondering who 3 top users have we lost?

AlexG

@morbusg herbert, jfbu that I know of.

morbusg

oh dear :(

CarLaTeX

13:22

@morbusg the third is Christian Hupfer, as written in the post

AlexG

@CarLaTeX Did he also delete his profile?

CarLaTeX

@AlexG yes

marmot

14:30

@AlexG June also happens to be the name of the marmot of the month. ;-)

Paulo Cereda

14:46

@AlexG It's my favourite month, not just because it's my birthday. :) I really enjoy the festivities!

GermanShepherd

Hi folks. Got a quick question. I have a pretty long text mxed with some math symbols which I am writing using eqnarray. The issue is, the text spills outside the textwidth.

This is what it looks like : \documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath,amssymb,csquotes}
\title{}
\author{}
\date{\vspace{-5ex}}

\begin{document}
texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex
\begin{eqnarray*}
&{}\textit{Input: }&{} x_1,x_2,\ldots,x_n;\text{$v$}\\

David Carlisle

@GermanShepherd never use eqnarray

GermanShepherd

@DavidCarlisle I tried tabular, but I m not able to get the text to wrap

and I want a wide margin for the whole document too.

David Carlisle

@GermanShepherd ouch eqnarray is deprecated even for list of equations but there don't you just want a description list?

@GermanShepherd

\documentclass{article}

\item[Output:] Is it possible to make change for $v$ using coins of denominations  $x_1,x_2,\ldots,x_n$?
\end{description}

\end{document}

GermanShepherd

@DavidCarlisle Almost like a description list, but I wanted it to be on the same line, not as keyword in the first and text in second line

David Carlisle

14:56

@GermanShepherd that is the default layout, with inline label

Sebastiano

@Skillmon I didn't know that :-) in German. It would be nice if you learned it.

@DavidCarlisle Hi

GermanShepherd

@DavidCarlisle Thanks. I tried it too, but the $x_1,x_2,\ldots,x_n$ part is aligned right beneath Output. I kinda wanna avoid that.

Sebastiano

@GermanShepherd Excuse me very much.

David Carlisle

@GermanShepherd you can customise the layout using enumitem so the label is to the left, or if you really don't want a list use a tabularx with preamble lX but 9999 tines out of 10000 an lX tabularx is better as a list

Sebastiano

@GermanShepherd I have activated the trasnslator of google

@CarLaTeX For 20th of the site.

GermanShepherd

14:59

@Sebastiano No problem

Sebastiano

@GermanShepherd Thank you.

@AlexG @CarLaTeX I'm sorry that three of the best have left, but why? Has something happened?

GermanShepherd

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath,amssymb,csquotes}
\usepackage{enumitem}
\title{}
\author{}
\date{\vspace{-5ex}}
\newcommand\litem[1]{\item{\bfseries#1.\space}}
\begin{document}
texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex texttexttex

\begin{enumerate}[]
\litem{Input:} $x_1,x_2,\ldots,x_n$; $v$.
\litem{Output:} Is it possible to make change for $v$ using coins of denominations $x_1,x_2,\ldots,x_n$?

@DavidCarlisle Using enumitem, the text still wraps beneath "Output" . Is there a way to avoid that, and move it out to the right?

David Carlisle

15:16

@GermanShepherd your litem disables the list formatting and just makes the argument part of the following text not part of the label so makes it harder to control the formatting, enumitem has dozens of options to control the list formatting labelwidth and listparindent in particular sorry no time now you may be best to ask a question on site

egreg

15:39

@GermanShepherd I think you want description:

\documentclass{article}
\usepackage{enumitem}

\begin{document}

\begin{description}
\item[Input:] $x_1,x_2,\ldots,x_n$; $v$.
\item[Output:] Is it possible to make change for $v$ using coins of denominations $x_1,x_2,\ldots,x_n$?

@GermanShepherd Do you mean something like this picture?

Prabhjot Singh

@AlanMunn a box within a column.

manooooh

17:13

@Sebastiano have a nice day! Yet I did not test those styles, you will have to wait :), but if @egreg is right then all the students that differentiate a vector from a scalar will be wrong, since our notation is inconsistent (we write \vec{v} but not \vec{\emptyset}?)

@Sebastiano You mean the answer to your question about colors? Sometimes the voting behaviour is strange: for this answer I got 5 upvotes, but several answers of me for moderncv did not get even one upvote. Seems I'm unable to understand why and when people upvote answers :-(

Paulo Cereda

@yo' ooooh

baxx

18:53

is it possible to shrink a minted environment? I want to make the entire thing ~20% or so smaller

Sebastiano

19:21

@Kurt Kindest Kurt....yes for my question about colours. I don't just see strange votes being cast, but also more. Don't worry, you're always welcome with me. :-) I don't do any more controversy, otherwise I get tachycardia :-)

@barbarabeeton Hi, and welcome.

Kurt

19:36

@Sebastiano have you done all corrections to your book needed or are you still in that process?

samcarter

19:52

@baxx Maybe you could try a smaller font size?

David Carlisle

@baxx as @samcarter says it's just text so \small should work.

samcarter

\begin{minted}[fontsize=\small]{Java}
(new Thread(() -> {
System.out.println("Hello");
})).start();
\end{minted}

David Carlisle

@samcarter oh you must have read the manual or something, I'd just have put \small before the environment:-)

samcarter

@DavidCarlisle Coincidently I had the manual still open from trying to answer tex.stackexchange.com/q/482818/36296

Sebastiano

@Kurt Frankly, I haven't touched anything yet :-). I'm adding some small parts, but in this period, as you can see, I'm logged on to TeX.SE, a little more often, because I'm getting bored :-). You know the moments of discouragement are many, I'm still waiting for my teacher for the first revision but we postpone almost always due to his numerous university projects.

Feature Requests have now also been migrated to GitHub. I have closed some of them so you might want to check yours. Since they have been migrated by the pgf-tikz-bot account, you won't get a notification unless you subscribe to the thread. github.com/pgf-tikz/pgf/labels/Feature%20Request

Joseph Wright

@HenriMenke Or you've been added as a dev ;)

mickep

@HenriMenke I just tried context-lmtx on a book project (200+ pages) with lots of math, and except that the equation numbers were not aligned correctly, I see no strange things (after a first glance). Did you try it out, yet?

Kurt

@Sebastiano Ah, I see. Let us hope he does not find too much issues ;-)

Sebastiano

CarLaTeX

@Sebastiano I think only one day

Sebastiano

20:10

@CarLaTeX Good thing, since I still see the stars for the cervical one :-). Now I also have sore throat and cough.

CarLaTeX

@Sebastiano See here: tex.meta.stackexchange.com/questions/8205/…

Henri Menke

@mickep No, I haven't tried LMTX yet.

Sebastiano

@CarLaTeX Upvoted! Can I tell you that 80% Christian is right? But since he came back honestly I've seen him in his different writing. I voted for your post just 2 minutes ago

@Kurt Are my images more beautiful than those made with TikZ? I'm joking

@HenriMenke Good evening

David Carlisle

@samcarter does it have a manual? I seem to recall @UlrikeFischer claiming it does, but I thought it was just hear-say.

Sebastiano

@DavidCarlisle Hi, David.

@CarLaTeX I still do not understand after two years if users with the shadow are connected in chat or are hidden.

Kurt

20:19

@Sebastiano :-)

samcarter

@DavidCarlisle :) Of course you wouldn't know yourself, but I can confirm that manuals are indeed a useful thing for all of us who have not written 95% of the packages themselves

Sebastiano

@CarLaTeX After two years I've changed too...I've become older but my experience here is little compared to many others. There would be a lot but a lot to discuss about your question.

Ulrike Fischer

@mickep mac users seem to have the problem that the preview doesn't show all chars of a pdf.

David Carlisle

@samcarter I have a gold tikz-pgf badge so obviously I know all about it. I think it's some kind of picture mode variant with a weird syntax with semi colons.

Sebastiano

@Kurt the images are also done with tikz-pgf and after I have modificated with adobe illustrator.

mickep

20:22

@UlrikeFischer I saw that on the list. I did not have that problem here (linux-64 and evince). I'm trying to make a minimal example of the mis-aligned equation number, but I cannot. Well, it is too late to do this now... :)

samcarter

@DavidCarlisle There had been a short time period in which tikz was inevitable, but now that @UlrikeFischer created the picturemondrian marmot, who would still need tikz?

Ulrike Fischer

@samcarter ? what did I create?

Sebastiano

@Kurt attention for the new user aahahhah she is a expert of computer :-)

Kurt

@Sebastiano Can you center the legende here? I think it woulfd look better ...

David Carlisle

@samcarter quite so

Henri Menke

20:51

@mickep I just installed LMTX. Nothing works. It doesn't find my fonts.

mailman.ntg.nl/pipermail/ntg-context/2019/094531.html

Sebastiano

@Kurt Certainly with Adobe Illustrator it's a minute at most. But for the images it will be care of the publishing house. The rest of the text is almost done.

Skillmon

@Sebastiano you mean it would be nice if I learnt Spanish?

Sebastiano

@Skillmon Wait till I'm lost :-) What is the initial question I asked you? I don't remember it :-(

Joseph Wright

@HenriMenke Enjoy your reply from Hans? ;) I expected something like it

Sebastiano

@MarcelKrüger Welcome to you and all enter

marmot

20:57

@samcarter Oh no!!!

Henri Menke

@JosephWright You mean this one? mailman.ntg.nl/pipermail/ntg-context/2019/094532.html

Joseph Wright

@HenriMenke Oh indeed

Sebastiano

@marmot Hi marmot.

marmot

@Sebastiano Ciao.

Henri Menke

@JosephWright Doesn't really fit into the mindset of the rest of the TeX world but whatever.

Sebastiano

21:00

@marmot do you like my images done with Adobe Illustrator?

Joseph Wright

@HenriMenke Have you talked to Hans about licenses before?

@HenriMenke Hans is of the DEK mindset, so I'm not sure that's entirely true

Henri Menke

@JosephWright BTW, here is the migration script for the SF issue trackers, which has also cost me time, yet I decide to share it because others might benefit from it. gist.github.com/hmenke/05e5754d188f1367bbcaa62ebc57397e

marmot

@Sebastiano Yes, but why do you need adobe acrobat for that?

Sebastiano

@marmot Acrobat?

Henri Menke

@JosephWright Then why didn't Hans license LuaTeX under a BSD-style license?

Joseph Wright

21:01

@HenriMenke Wish that had been available for beamer when Till did the migration to BitBucket ... we lost all the issues then

marmot

@Sebastiano Or illustrator. They seem not to be in orthographic projection. Is that on purpose?

Henri Menke

@JosephWright You can still migrate them now. My script uses the undocumented issues API of GitHub. You can read some unofficial documentation here: gist.github.com/jonmagic/5282384165e0f86ef105

Sebastiano

@marmot They are handmade with Adobe Illustrator and not with TikZ. I'm not as good as you are with such sincerity. You're superlative.

Joseph Wright

@HenriMenke But the numbers will all be out

Henri Menke

@JosephWright Same for PGF, but I don't think that matters.

Joseph Wright

21:05

@HenriMenke But they won't match commit messages, etc. (I'm thinking closed issues)

Henri Menke

@JosephWright Same for PGF, but I guess that is the price you have to pay. It also pretty much impossible to migrate from SF to GH properly because SF supports multiple trackers, whereas GH only has one.

Joseph Wright

@HenriMenke I think for a long time Hans just didn't want to say at all (at least for ConTeXt). Didn't Thanh pick GPL for pdfTeX ...

Sebastiano

Good night to everybody. Ciao a tutti.

Henri Menke

@JosephWright But wasn't LuaTeX translated to C from pdfTeX's WEB sources? I think that would have warranted relicensing.

CarLaTeX

@Sebastiano They are connected but not present

Joseph Wright

21:10

@HenriMenke But starting from a GPL source you can't just 'get out' of the GPL: it's rather the point

@HenriMenke It was done step-by-step

Skillmon

6 hours ago, by Sebastiano

@Skillmon I didn't know that :-) in German. It would be nice if you learned it.

@Sebastiano ^^^^

Joseph Wright

@HenriMenke Licenses are unfortunately extremely painful. Look at the LPPL: 1600 emails to get something that perhaps might have been done by using the MIT one ...

Henri Menke

@JosephWright I usually place my work in the public domain (or CC0), because I just don't care what people do with it.

Joseph Wright

@HenriMenke Totally see that, and I take a similar line myself where it makes sense. For LaTeX code, LPPL is the common position so I stick with it. (Of course, team code is pretty clear!)

CarLaTeX

@Sebastiano That's why we are always telling you to add an MWE to your questions.

David Carlisle

21:46

@HenriMenke that wasn't really an option as they derived from pdftex which was already GPL in large parts

Joseph Wright

@DavidCarlisle What I said!

@DavidCarlisle Looking forward to GitFlow for LaTeX2e? ;)

David Carlisle

@JosephWright possibly: been a bit tied up with work seen a lot of your repo-reorganisng commit messages go past but had to skip the details, hopefully I'll catch up:-)

Joseph Wright

@DavidCarlisle Bottom line: we are now set up with two branches that are ready to go, and babel has set off on it's own

David Carlisle

@JosephWright yep I got that far:-)

Ulrike Fischer

@JosephWright I got a number of babel issues a second time ;-(.

Joseph Wright

21:54

@UlrikeFischer Yes, because I've migrated them (although it seems to have only done one properly)

manooooh

@marmot thanks for the answer, it helped me a lot!! I am a bit curious, what issue do you think that you have found? O.O

David Carlisle

@JosephWright did you like my e-tex answer?

Joseph Wright

@DavidCarlisle Oh yes

Ulrike Fischer

@DavidCarlisle ?

Q: Use of \noexpand in the implementation of \TextOrMath for eTeX

In latexrelease 2015/01/01, there are two implementations of \TextOrMath: one for regular TeX, the other one for eTeX-like engines (more precisely: those which support \protected). My question concerns the latter: \protected\expandafter\def\csname TextOrMath\space\endcsname{% (...) } % no pro...

macros expansion definition protected-macro

Ulrike Fischer

22:02

@DavidCarlisle nice answer ;-)

I must say seeing the frenzy on the context list I wonder what will happen with the fontloader stuff ...

Joseph Wright

@UlrikeFischer Will be interesting ...

David Carlisle

@UlrikeFischer I imagine the existing one will effectively be frozen and the new ltmx back end code will diverge rapidly

Ulrike Fischer

@JosephWright yes. I'm just importing the last pre-LMTX version and testing it.

@DavidCarlisle I guess too. In the near feature we will be on our own.

Joseph Wright

@DavidCarlisle Not so sure: they are mainly stripping out stuff that's not 'needed'. They need Lua ...

David Carlisle

@JosephWright yes but what I gather from Hans description is that with a different back end architecture the font loading code is likely to be different, it will be in lua yes but not necessarily the same kind of beast.

morbusg

22:13

has anyone heard if development (/translation) of Cló has continued?

David Carlisle

@morbusg ?

morbusg

in a nutshell: re-implementation of TeX's algorithms in Clojure

David Carlisle

@morbusg ooh google/wikipedia knew nothing (other than references to the word meaning:-) I hope it fares better than NTS (re-implementation of TeX in Java)

Skillmon

22:32

@DavidCarlisle why do people want TeX to get insanely slow?

morbusg

@Skillmon not directed at me, but why I'd be interested is the code could be expressed in a more concise, easy-to-understand manner; not necessarily for using the software due to slowness, but learning.

marmot

23:30

@manooooh I wanted to automatize it, and use the \definecolor in a /utils/exec/ key to define the color. This only worked after passing [rgb] to the document class, \documentclass[rgb]{article}, say. (I can still add this but I think you need two commands: one to create separate arrows that extend the list and one that adds an arrow to a group).
