Hellooo, @CarLaTeX??
 
user280247
4:24 AM
I'm trying to suffle images on a slide, until now got this: imgur.com/4FHsG71
 
user280247
Any advice to make it look nicer?
 
5:22 AM
@santimirandarp This looks already good but where is Einstein? ;-) More seriously, I do not know how you are producing it but you could of course use a simple tabular to place the images.
 
6:15 AM
@manooooh Here I am!
 
@CarLaTeX heyyyy, wanna play Pinturillo?
The site is very quiet
 
6:35 AM
3.34 a.m. and I am listening to this song: https://www.youtube.com/watch?v=4jBDnYE1WjI
Going to the super will not be like before...
 
6:52 AM
@manooooh Let's try to do a couple of rounds :)
 
7:11 AM
@CarLaTeX wii, pick Italian -> private room -> Room Nº 8641; Code 123
 
@manooooh Give me the link again please!
 
8:01 AM
@CarLaTeX for the next we should choose the English language, they mix the languages!
 
@manooooh Yes, but in English is more difficult, bye!
 
@CarLaTeX we do not want it to happen again. Ok, bye

@UlrikeFischer Have you managed to look at l3build updates?
 
@JosephWright no not yet, trying to cleanup the files lists. But I looked at the pull request and it looks good. I only will additionally reset the environment variable texmfcnf so that "my" system doesn't interfere.
 
@UlrikeFischer OK
 
10:46 AM
@UlrikeFischer I should have explicit README support today
 
@JosephWright that would be good. How will it work? can I put a ctan-readme.md in the doc folder and tell l3build to rename it to README.md when making the ctan zip?
 
@UlrikeFischer That's more-or-less my plan: I just need to work out a few details ...

@JosephWright ^^^^
 
@UlrikeFischer :)
 
11:43 AM
@marmot I found your crystal ball. It is hiding in your avatar!
 
12:18 PM
@marmot The proof is probably difficult if one looks at the imaginary and real parts of numbers, but if one switches into the duck- and marmot space, the proof becomes very easy. If the duck and marmot space is not enough, one can add further tikzlings dimensions.

12:59 PM
@samcarter Of course ducks are real and marmots imaginary
 
1:11 PM
@egreg :)
 
2:03 PM
@samcarter I guess you could declare new plot marks, too. \addplot[only marks,mark=duck] ... will be a very popular choice, I think. ;-)
 
2:27 PM
Is tex.stackexchange.com/questions/452078/pylatex-change-font really considered off-topic? It is related to LaTeX after all and we also tend to answer matplotlib answers as well.
 
@Skillmon I think pytex questions are OK so long as it is close to the tex side of pytex and not turning towards being a general python syntax question. That one seems fine to me, if a little terse given that many people on site probably have never even heard of pytex:-)
 
3:12 PM
@DavidCarlisle Is that different from pythontex?
Possibly yes.
Embedding TeX in Python? Now, that's exotic.
 
@FaheemMitha it's the other way around.
 
@Skillmon You mean TeX calling Python vs Python calling TeX?
 
@FaheemMitha yep.
 
@FaheemMitha pylatex builds a LaTeX document from python code.

3:59 PM
@marmot haha thanks...Well I wasn't sure, I'll try to describe wave-particle duality, so maybe ill add him. The first slide is supposed not to be ordered, but with the images distributed on it...
 
@Skillmon Oh. Well, that's fancy. Any examples on hand?
 
4:14 PM
Of course you could place the pictures along a wave or wave function that you draw e.g. with tikz. You do not actually have to draw the thing, e.g.
\begin{tikzpicture}
\path[decorate,decoration={markings,
mark=at position 0.1 with {\node{\includegraphics[scale=0.3]{example-image-a}};},
mark=at position 0.5 with {\node{\includegraphics[scale=0.3]{example-image-b}};},
mark=at position 0.8 with {\node{\includegraphics[scale=0.3]{example-image-c}};}
}] plot[variable=\x,domain=0:540] ({\x/50},{2.5*sin(\x)});
 
@FaheemMitha from the documentation: jeltef.github.io/PyLaTeX/current/examples/full.html
@DavidCarlisle "I think the large foot going off page must count as a bug" WHAT HAPPENED?
 
@egreg as for tex.stackexchange.com/a/452109/121799 : I guess this will simplify things quite a bit. You can then write equations like $\delta\cdot\delta=\delta/\delta$. If all quantities are denoted \delta this equation won't be wrong nor imply that $\delta=\pm1$. ;-) Some friends of mine actually got quite close to a universal letter in their handwriting. ;-)
 
user280247
4:32 PM
@marmot almost perfect but the function isnt plotted...
 
user280247
4:46 PM
@marmot oh now I understood. I supposed there would be a function below the pictures. Thanks
 
@Skillmon I expect I will find that I'm mistaken and it's a documented feature.
 
@santimirandarp The function can be plotted by replacing \path with \draw, in which case you may add smooth to the options of plot, i.e. plot[variable=\x,domain=0:540,smooth,samples=31] or something like this.
 
user280247
perfect, I'll try it out
 
@santimirandarp yes, this defines the path along which the pictures are placed. For instance, if you want to show mathematicians, you may choose a Gaussian and put Gauss (or @egreg?;-) right on the maximum of the curve. BTW, tikzsymbols has \SchrodingersCat symbol, which you could use instead of Schrödinger. ;-)
 
user280247
Fine...so now, using \draw, the pictures should be linked by the function...but it isnt. I can show you an image
 
user280247
4:56 PM
@marmot didn't know he is mathematician, I have so many questions XD . Joke.
 
@santimirandarp This forum host some highly educated people, and some who put pineapple on a pizza. ;-)
 
user280247
@marmot Are those mutually exclusive? :)
 
@santimirandarp No, I didn't write xand. ;-)
 
user280247
haha
 
@UlrikeFischer Working on the README business: almost sorted, but some weirdness to track down :(
 
5:02 PM
\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{decorations.markings}
\begin{document}
\begin{frame}[t]
\frametitle{Placing pics along a function}
\begin{tikzpicture}
\draw[blue,very thick,postaction={decorate,decoration={markings,
mark=at position 0.1 with {\node{\includegraphics[scale=0.3]{example-image-a}};},
mark=at position 0.5 with {\node{\includegraphics[scale=0.3]{example-image-b}};},
mark=at position 0.8 with {\node{\includegraphics[scale=0.3]{example-image-c}};}
}}] plot[variable=\x,domain=0:540,smooth,samples=31] ({\x/50},{2.5*sin(\x)});
@santimirandarp ^^^ this is a complete example.
@santimirandarp I should have mentioned before that you need to put the decoration in a postaction since otherwise indeed no curve will be drawn...
 
user280247
Coool, thanks. Let's see...
 
user280247
@marmot haaa I like it
 
5:19 PM
@JosephWright we are in total agreement I see!
 
5:32 PM
@DavidCarlisle :)
 
5:48 PM
@DavidCarlisle @UlrikeFischer github.com/latex3/l3build/commit/…
 
6:13 PM
@UlrikeFischer, @DavidCarlisle One or two minor issues still to fix ...
 
 
2 hours later…
8:03 PM
@DavidCarlisle, @UlrikeFischer Hopefully, we are now good to go with l3build: I'll send to CTAN
 
8:27 PM
@Skillmon Thank you.
If there is a graph, it really should be using some Python library to build it, though.
 
@FaheemMitha one can use matplotlib for it. It can export to pgf and PDF (among other formats).
 
@Skillmon Yes, that's what came to mind.
But would one then need pytex at all?
 
@FaheemMitha I think this is already mentioned in the docs
 
I was thinking of a pytex use case.
 
@FaheemMitha one could do calculations and stuff. But I usually do it in another way, writing a python script which builds all the stuff I can't calculate with TeX and then outputting this to a file which I can then \input.
@FaheemMitha I never used pylatex before.
 
8:37 PM
@Skillmon Yes, doing it that way is standard.
But maybe pytex allows a convenient way to embed that in a LaTeX file? Like Sweave?
 
@FaheemMitha don't know. As I said, I never used it.
 
@Skillmon Me neither.
 
@FaheemMitha you have to differentiate though. There seems to be pytex and pylatex which don't seem to be the same. I used neither of those though.
 
8:54 PM
@Skillmon Well, that's confusing. I've used pythontex.
 
@DavidCarlisle @JosephWright in the announcement of luatex-ja: "* small fix for upcoming luaotfload v2.9" ;-)
 
9:13 PM
@UlrikeFischer you broke their package?
 
@DavidCarlisle looks so ;-). But I forwarned them osdn.net/projects/luatex-ja/ticket/38627.
 
@UlrikeFischer you didn't try out your Japanese I see
 
@UlrikeFischer Oops?
 
Seek for the code that was broken.
In TeX and LaTeX it dwells.
There must be councils taken
Stronger than bugs and spells.
Soon shall be seen a token
Of answers near at hand.
The LaTeX Team shall waken
And the Tikzling forth shall stand.

@JosephWright i don't think that there is a serious problem - they would have written to me. It means that they looked at it, which is reassuring.
 
@UlrikeFischer I was too tired the other day, what was the outcome of that factor=nil issue, did you do something in luaotfload or do I need to try to construct an example to push back to Hans?
 
9:23 PM
@DavidCarlisle I didn't check yet. After I realized that I missed one file I decided to sort out the filelist first. But it is on my list. I will look at it later.
 
@UlrikeFischer thanks
 
hello @BrunoLeFloch.
 
@FaheemMitha and that again is a different thing :) So to summarize there are at least 3 similar named things: pytex, pylatex and pythontex. pytex seems pretty dead (last code contribution was in 2005 according to their sourceforge site), pylatex seems pretty active and uses Python source code to generate LaTeX code (either full documents or snippets, both possible). And then there is pythontex which has a completely different approach being more like Python call from within LaTeX.
 
@Skillmon I see. Thank you for the summary.
pytex and pylatex are really similar names.
 
Hello @UlrikeFischer. Not staying, I was just looking at archives around May 24 to see what latex3/#463 was about.
And I think that that confusion is reasonable given that * in \section* doesn't look like an argument (in particular mustn't be wrapped in braces) but in the code it shows up as a boolean #1.
 
9:36 PM
@BrunoLeFloch I remember that discussion. Imho not really important.
 
 
2 hours later…
11:50 PM
@UlrikeFischer Yes, that seemed to be the consensus at the time.
@BrunoLeFloch Thank you for taking a look. I forgot to add a link to the discussion, as I should have, but it sounds like you found it anyway.
Should I add a link to the discussion now? It looks like edits are still possible.
Does anyone know an easy way to jump back to a particular day in chat?
