quack

@PauloCereda Quaken!

@CarLaTeX ooh more ducks

@PauloCereda We love ducks <3

@CarLaTeX awww <3

9:29 AM

@UlrikeFischer I think not. It worked for me in a book with Lucida small caps. I'll try again with a small file when I'm done with something else here...

10:26 AM

@CarLaTeX especially with hoisin sauce

@DavidCarlisle You're mean

@CarLaTeX hmm but:

@CarLaTeX you are mean

@DavidCarlisle I am mean, too

@DavidCarlisle oh no

11:30 AM

@CarLaTeX I suppose me too... I had lacquered duck as Valentine dinner yesterday (yummy).

@Rmano oh no

11:42 AM

Flesh is weak...

@Rmano but the spirit is willing? :)

@UlrikeFischer +500:-)

12:14 PM

@PauloCereda well... Most of the time ;)

@HaraldHanche-Olsen I ate bigoli al sugo d'anatra (a kind of pasta with duck sauce) yesterday with @egreg... but don't tell Paulo ;)

2:44 PM

@PauloCereda that's great news!

@UlrikeFischer That one changes ß into ss in the small caps. (It is strange that one has to enable small caps, I will ask about this in the list.)

@mickep YES LUCIDA <3

@PauloCereda Ooh, yes, indeed!

3:52 PM

To brighten up your day: twentytwowords.com/…

Ulrike Fischer

@mickep I don't have the font. But your example doesn't use a capital ß, so it doesn't replace (if at all) an non existing glyph but substitutes an existing one, and that is rather easy to implement.

4:15 PM

I'm trying to understand the first example in tex.stackexchange.com/a/528479/3406

But I'm a bit puzzled about what is going on with the following bit.

\makeatletter
\newcommand{\newappend}[1]{%
  \begingroup
  \protected@edef\next{\endgroup\noexpand\g@addto@macro\noexpand\newslist{#1,}}%
  \next
}
\makeatother

Specifically, the usage of \begingroup and endgroup, and the usage of brackets.

I.e. \begingroup is supposed to end with \endgroup, but \endgroup is preceded by a bracket which closes at the end of the line?

There's something about

> These techniques also don't overwrite the \next macro

which is probably relevant.

Oh, never mind. I guess those brackets are part of the defn of \next.

5:14 PM

@FaheemMitha no as we discussed yesterday the tokens in the definition are not evaluated at all, so the \endgroup only ends the group after \next has been expanded, so it matches the opening \begingroup

Ulrike Fischer

@DavidCarlisle it is a pity, I have now 234562 ;-)

@FaheemMitha why not simply \def\newappend#1{\edef\newslist{\newslist#1,}} ?

@UlrikeFischer give me another 500 and try again tomorrow?

@DavidCarlisle Yes, as I was reminded, expansion is followed by execution.

@FaheemMitha your version in the question with a newline after #1 has "interesting" behaviour:-)

@DavidCarlisle I'm glad you find in interesting.

I must confess that I have a hard time remembering that whitespace is syntactically significant.

5:20 PM

@FaheemMitha the usual missing % at end of line just adds spurious space in the output (you added two spaces) but that one completely changes the definition.

What are the rules about how many tokens are expanded before they are executed? Are they done in groups?

@FaheemMitha it's only the first token that is looked at, either it expands if it is expandable or it is executed

Exceot that per tex.stackexchange.com/a/4747/3406 TeX also has some expansion-only mode, for extra fun.

@FaheemMitha yes in an edef or \write etc, you are only doing expansion

@DavidCarlisle I guess that's reasonable.

Hence the \protect thing.

5:34 PM

@FaheemMitha well that's a latex macro rather than a tex thing but yes

@DavidCarlisle \protectis LaTeX? That wasn't clear.

@FaheemMitha why isn't it clear?

@FaheemMitha usually it's just \relax but at other times it's defined by \def\protect{\noexpand\protect\noexpand}

@DavidCarlisle Because presumably non-LaTeX TeX would need similar functionality. Since none of this seems LaTeX specific.

@DavidCarlisle Yes, I was just reading that what it expands to is context-dependent.

@UlrikeFischer Ah, I see. Sorry, I misunderstood you. The capital eszett is in the font, and it does not get converted (neither in roman nor in small capitals).

Ulrike Fischer

@mickep our code doesn't convert an existing capital eszett either, it only uses SS if the capital eszett doesn't exist at all in the font.

A: How can I visualize a Torus with three paths?

5:58 PM

I have a naive question. In this answer how does one run the code?

Here is an answer that uses Asymptote to produce a vector graphic result: The actual pdf file may be found, for now, at this location; but I don't think you will have any trouble compiling it (although it may take a while--about 77 seconds on my computer). I've omitted the LaTeX wrapper and div...

Because there no \beign{document}.....\end{document}

6:15 PM

Is the most recent version of interface3 still the Released 2019-11-07 version?

@FaheemMitha no 2020-02-11

@DavidCarlisle Oh. I don't have that one yet.

@FaheemMitha you want the one that matches the code you have, so you don't want a newer one. 2020-02-11 is the one in texlive

@Shamina It's asymptote code --- if you copy the two parts of the code into a file called for example test.asy and then run "asy test.asy" (at least, in Linux with a full texlive installation) after a good while you'll have a file called test.pdf with the image.

6:58 PM

@Rmano Many thanks, I just followed you, voila it worked

@Shamina you're welcome!

@Rmano Sorry a last question, if I can. In his second asnwer. He gave a tex format file. Can we compile it by latex (.tex) way?

I was trying it it showed file texstudio_pg5958-1.pdf'` not found

@Shamina In principle yes --- with pdflatex, embedding it in a \begin{asy}...\end{asy} but it fails for me, exactly with the error you mention. No idea why. On the other hand, given that it runs for 60+ seconds, it seems to me that it's not practical to have it embedded...

7:13 PM

@Rmano Thanks! I see. I used it without the environment of \begin{doc... And I compiled it using .asy way, it was kind of quick for me though

@Shamina it seems it's supposed to be so, look at tex.stackexchange.com/questions/129084/…

you need to run asy by hand, it seems.

@DavidCarlisle Yes, I realise that.

@Shamina fast computer you have...

Actually, there's a new release of the Debian packages, 2019.20200210-1. Is it worth upgrading? Are there significant improvements over 2019.20191208-4? That's the one I currently have installed.

@Rmano I agree you with you. I am just setting parameters according to my case now. It's my boss gift

7:27 PM

@FaheemMitha latex2e 2020-02-02 is a very big latex release, so you might want it (includes expl3 by default and a big update to the font selection mechanism)

@JosephWright -- I keep adding items to the math section of the Often referenced questions list in meta, and I'd like to add a "mini-toc" at the top to make things easier to find. But I don't know how to add link points to the subheadings. Is there a reference I can look at?
