@DavidCarlisle ^^

In other news, does anybody use hunspell with TeX documents, besides me? :)

@PauloCereda ^^ I had to look that up.

@DavidCarlisle LOL you are my hero. <3

@DemCodeLines I tried to contact someone who is in charge of that site an the contents, because it is indeed popular and leads to many questions here. I couldn't reach anybody, so there is no little warning sign: Attentiones!

I wish there was a good guide on how to declare pgf shapes. >_>

Hi guys

I've been running into some trouble configuring gnuplot and I'm wondering whether questions about it should be posted on TeX - LaTeX or Stack Overflow

(I've seen some on both)

@Danu Configuring gnuplot is off topic. Making it cooperate with TeX is on topic.

@egreg Okay, thanks. Should I expect (significant) issues when trying to do the latter?

For now, I'm just configuring the plot, but after that I intend to copy-paste it into TeX.

(for instance, is high sampling rate an issue in TeX? I'm going to be doing ~250,000 samples)

@Danu pgfplots is able to call gnuplot

@egreg Right, that's what I saw.

@Danu Then it depends on what you want to do. There's also gnuplottex, which has smaller impact than pgfplots, but also less features.

I guess I'll delve into once I manage to get that god-damn "hard" x-axis to disappear.

@Danu If you want to plot for a thesis/paper/poster, you need much less datapoints. If you want to do analysis, TeX is not the right tool. So i guess raw data -> analysis -> presentation.

@Johannes_B I need to plot a wildly oscillating curve for my topology notes: It's a standard example for a certain "pathological space" (connected, path connected but not locally path connected)

It really needs to have the wild oscillations

@Danu Oh, ok.

The picture is already implemented using \includegraphics but I'm trying to do better and "keep it all inside" (currently these are the only imported pictures out of ~50 in the whole thing, because I spent a lot of time keeping it TikZ-only, but it really didn't manage to do such precise plots)

All in all, a luxury problem---but with German universities' 2 months of holidays in Spring, I have time ;)

@Danu What may be better would be to plot the function until the point where it starts to oscillate too fast and then manually draw in a fill polygon for the rest since by definition, you always have issues sampling the function.

@Danu For example, you could plot sin(1/x) for 0.1 < x < 5 and then draw a rectangle for the region 0 <= x <= 0.1.

@JP-Ellis WIth the high samplying rate I have now it is actually smooth enough to deceive the eye (~250.000)

@JP-Ellis And this definitely looks inferior (I tried)

hmm, no sure why it didn't highlight it like code :/

You need all those spaces in front of every "paragraph"

Btw the compat=1.13 thing gives me an error

^no idea

(and still, it didn't mark it as code :/,  I think the whole message has to be indented)

@JP-Ellis Yes, it does

@JP-Ellis I have no idea how to work with the command line properly---I know how to update my packages using the MikTeX package updater though

and I did that... 2 months or so ago

Oh, you're on MikTeX, then there's no command line involved :)

Could it be that I'm already out-of-date? After 2 months?

haha, it goes fast :) PGFplots got some updates very recently which made it work a lot better with LuaLaTeX

aw, okay :\

There are some problems with my Updater though...

Somehow it doesn't manage to update sometimes... I finds the packages that can be updated but then doesn't allow me to select them.

hmm, can you be more specific?

I'm no longer on windows, so I don't remember exactly, but I seem to recall that there were issues with packages installed locally vs system-wide

@JP-Ellis Oh..

That's the error I get when I try to select any of the packages (also note that the "Select All" option is greyed out)

locally meaning in your user directory. Have a look to see if you have any packages installed in the user directory and delete them. Then run the system update and hopefully it will be happier?

Now I just did what it said and let the wizard run---it actually did some stuff. Maybe it'll be happy on a second run-through?

yup

Welp...

actually, the first run may have just been the updater updating itself (which has to be done on its own), and then the second run it can go ahead and do everything else

Ah...

@JP-Ellis It still doesn't compile.

@Danu there were questions on site about miktex yesterday, apparently the server was down, is it back now?

The \addplot line gives an error now.

@DavidCarlisle I just successfully updated.

(so I think yes)

@Danu What's the error? Could you also try compiling with lualatex instead of (presumably) pdflatex?

@Danu I know nothing about miktex or pgfplots so I'm the ideal person to help:-)

@JP-Ellis Okay, I'll give that a shot.

What are the differences between all those TeXs? Sigh, so much to learn

Okay, that works @JP-Ellis.

However, the plot is not quite good enough for me, but okay.

You can see it bugging out a little bit on the top and bottom

Still much better than I expected.

It's also a lot slower than gnuplot

LuaLaTeX is another implementation of LaTeX (meaning that everything that LaTeX does, LuaLaTeX can do too). But LuaLaTeX also offers a Lua backend which can help get around some of the limitations of pdfLaTeX

(I have no idea what Lua is)

@JP-Ellis that's a rather optimistic sales pitch, but more or less, yes.

hahaha, I knew that I was going to be corrected :P

@Danu Lua is a scripting language (like Python, or sh if you want)

@DavidCarlisle What would be your 1-2 sentence run-down of LuaLaTeX vs pdfLaTeX?

@JP-Ellis note that luatex is in beta, and full compatibility with tex is explicitly not a design aim (and not achieved) and (unlike xetex) currently is too unstable to be configured in a way that it passes the latex test suite. (That doesn't mean it's not useful:-)

@DavidCarlisle Fair enough. For the average user though, under what circumstances will something work in pdfLaTeX but not LuaLaTeX?

@Danu I should mention while I remember: If you're going to use PGFplots and have many sampling points, you should have a look at the externalization library from TikZ. It will prevent you from having to regenerate all the plots every single time you generate your main document.

Oh god, going down the rabbit hole

(all my friends already laugh at me for putting in the effort to generate pictures in TikZ instead of PowerPoint)

@JP-Ellis hopefully not so often, but for example the next version of luatex aimed for texlive 2016 removes dozens of primitives and Joseph and I have spent many many hours trying to ensure that the average user doesn't notice too much and latex will still work, but even now with texlive 2016 pretest due to start in a couple of weeks if you use the development version of luatex (0.89, currently) hyphenation doesn't work, hyperref doesn't wrok, minted doesn't work, color and graphics..

yikes, I use those things!

... only work if you use the new luatex option that is currently on my machine.... and so it goes. probably it will all just seem to work by the time the DVD is pressed but the underlying tex engine is not stable at all.

@DavidCarlisle Thanks for the clarification. I really really hope that the transition will go pretty smoothly then... I really like the extensibility that the Lua backend offers

@Danu lots of people do, they will work fine with the version of luatex that you have, and they will work fine by the time you update luatex by any normal means,

@Danu I love that you're using TikZ over PowerPoint :)

@JP-Ellis I love it too! But it takes a lot of time

@Danu Initially yes, but you get perfection in return :D

(asymptotically speaking that is)

@JP-Ellis Indeed, I'm already unsatisfied with my first few pictures by now ;)

Back from the mass. What did I miss?

silence

shhh, I should be sleeping :P

@JosephWright all mentioned duplicates in a circle: tex.stackexchange.com/questions/295116/…

@PauloCereda me being at a mass service? (oh, and visiting a perfect Indian restaurant :) )

btw, looking for a cool name for a package for composing journal issues from single articles. Any ideas? @Paulo?

@DavidCarlisle I'm really happy I already printed my thesis!

@yo' Uncle Scrooge used to have a newspaper in the comics, but I cannot find the proper name in English. :(

@PauloCereda you think the title should be that fancy?

@yo' I was just curious to know the English name, it could be catchy. :)

Duckburg Times?

@yo' In Portuguese, it was called A Patada, but Wikipedia only offers the Italian version of the name.

@yo' The join package

@StefanKottwitz Sounds good, but a bit ... too bold?

maybe yojoin ...

@yo' in short: yoin

@StefanKottwitz Yes!!!! @Paulo ^^ agree?

@yo' or jojo for join jornal or journal join

@StefanKottwitz yojo

@PauloCereda ”L'eco di Paperopoli“?

So: yojo or yoin? What do you think? @Paulo

@yo' combine? Oh, no! It's taken!

@egreg yombine? Oh, no! Sounds like some drug!

@yo' I like yoin

@egreg So do I, I also think it's a bit clearer than yojo

I don't want to take join because 1) I don't want to use a generic word and 2) I don't want to take such a prominent package name for something that need not turn out well

@yo' And the logo: ⧉ (U+29C9 TWO JOINED SQUARES)

@egreg I don't think I need a logo, but I'll consider this :)

@JosephWright I think you got mail.

@yo' Yes, all OK, just have to add it to the list

@JosephWright ok, thanks

now, wish me luck with getting \write18 to do all I will need for the job.

@yo' Good luck!

@yo' -- oh, great gobs of good luck! (we don't even try to put together a journal in a single run. too many authors use too many incompatible packages. ams journals are put together with a perl script. and tugboat is finally just a bunch of files -- could have latex, plain tex, or context, as well as requirements for pdftex or xetex or luatex; impossible to combine, and fortunately, the printer is understanding and competent.)

@yo' especially if using luatex:-)

@DavidCarlisle We're not as lucky as you, who can enjoy LuaTeX 0.89

I see @egreg is criticising my document classes again.

@DavidCarlisle The best document class in the LaTeX world?

@egreg I realise typing make is a bit technical for you.

@egreg that one, yes.

@DavidCarlisle I like to typeset documents, not fighting with Hans. ;-)

@egreg oh I don't use tex for typesetting we use APP (3B2) for that:-)

@DavidCarlisle I'm old fashioned, you should know

@egreg s/fashioned//

@barbarabeeton that's not the goal. The goal is to run pdflatex on each article separately, but to use shell escape inside the root document and then only \pdfinclude the articles in the issue.

@DavidCarlisle is there anything like write18 in luatex?

@yo' there is write18 in luatex now but if you build from development it's gone. those kind people in the latex project provided shellesc package in the 2016/02/01 release which provides \ShellEscape which works on all tex engines. (uses os.exec in lua \write18 everywhere else) 9actually it overloats \write18 so that syntax works as well even in new luatex)

Is this some "we'll destroy all good in luatex" policy?
