A: What does the word "pizza" mean in Italian?

I agree with what was said in the other answer and is comments, "pizza" and "pie" are different words in Italian, and it's also difficult to translate "pie", because the meaning may vary according to the context. If you know a bit of Italian, I think you'll find interesting this speech by prof...

@Sebastiano Hmm? You received an answer and accepted it the same day. So I don't understand what you're asking.

@HaraldHanche-Olsen ooh

Harald Hanche-Olsen

@PauloCereda The total ooh count stands at 7280 (soon to be 7281). With you responsible for 6474 of them, that's still 806 ooh's by others. Most of them probably inspired by you. ;-)

CarLaTeX

@HaraldHanche-Olsen Oooh

Harald Hanche-Olsen

@CarLaTeX too many o's, doesn't count (there are 675 oooh's)

CarLaTeX

@HaraldHanche-Olsen Doesn't the last ooh of the oooh count if you do a find?

Harald Hanche-Olsen

10:03 AM

Now I got obsessed with searching with more and more o's. It ended here. All shorter versions produced hits.

Paulo Cereda

@CarLaTeX LOL

@HaraldHanche-Olsen ooh

Harald Hanche-Olsen

@CarLaTeX No, the search looks for whole words. Compare the search link I posted (1 hit) with the one with one fewer o's (3 hits): The hit from the former is not among the hits from the latter.

CarLaTeX

@HaraldHanche-Olsen Ooh

Harald Hanche-Olsen

@CarLaTeX :)

@HaraldHanche-Olsen The answer is good and it works. There are some question where I have accepted (quickly) the answer. Just only for this reason.

Would appreciate thoughts (@egreg?)

Is it possible to ship python scripts with TeX Live? I know that TeX Live packs its own Perl (at least on Windows), but I don't think it includes Python. Would they ship a python executable? Or should I create a standalone binary for Windows versions?

Ulrike Fischer

@Skillmon there are lots of python scripts in the scripts folder.

Faheem Mitha

@DavidCarlisle ;-) Freiburg im Breisgau?

Yes just a quick side excursion for a couple of nights

Joseph Wright

2:47 PM

I see Herbert is trying of l3draw ...

... I wonder why

@DavidCarlisle Ausgezeichnet

Skillmon

4:40 PM

@UlrikeFischer but does TeX Live ship a version of Python on Windows, or do Windows users have to install a Python environment on their own (I have no TeX experience on Windows, at all)?

Ulrike Fischer

@Skillmon imho the python must be installed externally.

Skillmon

@UlrikeFischer so creating a standalone Python executable for Windows would indeed make sense... (Windows is a strangely inefficient system)

Ulrike Fischer

@Skillmon Why is this different to linux? Can you assume there that python is always installed? And if yes, which version?

Skillmon

@UlrikeFischer almost on every distribution there is a Python version installed. The main difference is whether python symlinks to python2 or python3, with Arch linking to v3, but on my mobile python symlinks to v2.

The reason I'm asking: gitlass.de/jonathan/listings-ext.py

I created a small python script which builds upon the idea of listings-ext.sh but exports named code blocks instead of alphabetically numbered ones.

(maybe I should choose a different name, I'm open for suggestions)

Joseph Wright

@Skillmon Er, not installin something that's not widely used doesn't seem inefficient

Skillmon

4:53 PM

@JosephWright but Python is widely used.

@JosephWright and the fact that in Windows almost every program ships its own dlls of the same library already used by 1000 other programs installed...

Joseph Wright

@Skillmon Not really, in the grand scheme of 'all Windows installations'

@Skillmon Depends on your experience: Word, Excel, Powerpoint don't

@Skillmon We are back with @DavidCarlisle's point that people here are massively atypical of computer users

@Skillmon So that way they work ...

Skillmon

5:12 PM

@JosephWright no problems with my Arch installation, my programs work. Also you can't tell me that most of the users use everything a massive 20GB+ default installation ships with.

Marcel Krüger

@Skillmon If I remember correctly Arch doesn't install Python by default, it has to be installed manually too. (Of course, it is a bit easier than on Windows because of package managers)

schtandard

5:43 PM

@Skillmon You could just tell users of your package to install python. If it's really that widely used, most people will already have it. (Otherwise you are just adding to the "problem" you see emerging from Windows not having python by default..)
(Note that e.g. `glossaries` requires you to install Perl for some features, so this is not unheard of.)

Skillmon

@schtandard but TeX Live ships its own Perl in Windows, IIRC, so that's not really a problem there, if I'm not mistaken.

schtandard

@Skillmon I don't know, I use MiKTeX which doesn't.

Faheem Mitha

6:10 PM

Python is priority standard on Debian. Meaning it's expected to be present. Other standard packages are (Open)SSH and Exim, the default MTA.

I'd say it counts as widely used.

Skillmon

@FaheemMitha finally someone on my side :)

Faheem Mitha

The Windows ecosystem is different, I think. But I suspect that there are proprietary packages that embed Python. And non-proprietary too, of course.

@Skillmon Well, Windows is different from the free Unix-like systems. The operating system is different, the developer culture is different, and the user culture is different.

But having said that, I think it's likely that it's widely used on Windows too.

Is there a dominant/popular Python installation package for Windows? I don't know.

But why would one need to use Python with TeX? It might be better to use Lua, then you can tightly integrate things if you need to do so.

I just the other day, literally, came across a blog post of something who appeared to be stuck in a previous era, TeX-wise. I tried to tell him about the options that were now available, but he wasn't interested. Though he did reply politely.

At one point he talked about writing Python code to output LaTeX code. IMO, such aproaches are now obsolete. At least, I would not use them.

Skillmon

6:25 PM

@FaheemMitha well, my Python skills (though not stellar) are better than my rudimentary Lua skills. I can customize my window manager (which is scriptable in Lua), but writing code in Python is easier for me. Also Python is the better language for test evaluations, I use it frequently in conjunction with TeX, plotting and calculations are done in Python, text is done in TeX. The only thing the Python code outputs are macro definitions which store the results of the calculations.

Faheem Mitha

@Skillmon IMO, Python is a better user experience than Lua in virtually all respects. Though I believe Lua is faster (but I have not timed it). Lua is a pretty minimal language. But if you are not doing anything complicated, you can do it in Lua too.

@Skillmon It might be possible to call out to something else for calculations. I'm not sure what the Lua support for computation is.

See my earlier question about Julia...

Skillmon

@FaheemMitha Lua is most likely faster, yes, the design is much slimmer

@FaheemMitha Python has numpy, scipy and matplotlib, it is great for computational things (though of course relatively slow, but coding needs near to no time)

Faheem Mitha

@Skillmon Oh, sure, Python has a ton of stuff. Unfortunately calling Python from Lua doesn't seem to be that well supported.

OTOH, Julia does seem to have explicit support for being called via a C bridge.

Skillmon

@FaheemMitha only because no one has implemented it, Lua is made to be easily extensible.

Faheem Mitha

The one obvious language to check for would be R.

@Skillmon I did a quick check, and there appear to be a couple of projects, though I have not looked into it.

@Skillmon Some cooperation is also required at the Python end.

It's probably possible to add functionality to Python to make it easier to call from Python (though this is just random speculation on my part). But it would most likely have to be implemented by the developers.

Actually, it might just be this one - github.com/bastibe/lunatic-python

And it's not in Debian.

Skillmon

7:21 PM

Can any Windows user tell me how an absolute path which is understand by the TeX engines looks like? Is C:\/Users/<someuser>/Documents/interesting.file correct or should this be C:/Users/<someuser>/Documents/interesting.file?

Joseph Wright

@Skillmon Second one

Ulrike Fischer

@Skillmon C:\Users\User\Documents\some-file.tex (for tex with slashes naturally)

Skillmon

@UlrikeFischer I thought the TeX engines use forward slashes, also in Windows. So correct would be \input{C:/Users/User/file.tex}.

@JosephWright thank you (also to @JosephWright)

Ulrike Fischer

@Skillmon yes slashes, but why do you need an absolute path? I normally wouldn't expect this in a tex package.

Skillmon

7:38 PM

@UlrikeFischer because the script listings-ext.sh uses absolute paths in its output, and while my listings-ext.py doesn't by default it should be able to mimic that behaviour.

Faheem Mitha

8:35 PM

Does anyone know if it is possible to create a fillable PDF with a drop down menu using only TeX?

schtandard

@FaheemMitha It is, see section 7 of the hyperref manual.

Faheem Mitha

After doing a search on TeX SE, possibly yes, using hyperref. But it's unclear whether it will play nice with standard/proprietary PDF software.

@schtandard Have you ever done so? And can the resulting PDF be filled using Acrobat software, for example. Not to mention all that third party stuff out there.

schtandard

8:52 PM

@FaheemMitha Not really, only in connection with some questions here. There are usually differences between the different viewers, but afaik Adobe usually has the best support here. But as I said, I don't really have much experience here.

Faheem Mitha

@schtandard Ok.

Ulrike Fischer

@FaheemMitha sure why not. It creates a standard form field.

Faheem Mitha

@UlrikeFischer Ok. Good to know. Thanks.

I suppose this fillable thing is part of the PDF standard as well?

barbara beeton

9:13 PM

@UlrikeFischer -- There seem to be some problems saving the filled-in material. There are several questions on the main site that deal with this -- search for "save fillable pdf".

Sebastiano

Good evening to all users.

Is there someone that can help this user, please? Thank you.

Q: Is there way to produce an integral sign with a loop at the top?

I want to use this symbol for the product integral: Perhaps with a bigger loop, too. What's the best way of building this notation?
