@marmot do you know if it is possible to reward an answer being the owner of the question? Do we have to press "start a bounty"?

marmot

@manooooh You need to wait some time (2 days?) before awarding a bounty. But please do not give a bounty to me, I have more than enough points.... ;-)

manooooh

@marmot I went to older questions and it only says "start a bounty". Is that the correct button?

marmot

@manooooh Yes, I think so.

manooooh

Ok, thanks!!

I figured out that I do not have 1.16 version of the TikZ-PGFPlots package. I use MiKTeX so I went to "MiKTeX Console" -> "Updates" and updated all the packages. However, pgfplots was not there, so I am forced to update it manually. I am using this answer:

27

A: How to install a current version of TikZ?

The tikz offical update cycle is rather slow. However, development goes on and the latest build can be found here (tikz builds). The build has to be installed manually, but comes in the correct tex-tree-structure already. For Windows users who use MikTeX, it is advisable to create a local-tree t...

The step (2) says "Create a new folder e.g C:\LocalTexFiles", but I have done this before to install another package (the root is "C:\localtexmf")

In there, I have a folder called "tex", and inside it I have "latex" folder and inside I have "tikz-uml.sty". However, the pgf_3.0.1a.zip file has inside it the following folders: (1) "doc", "source", "tex"

(and inside "tex" there is one folder called "latex"

As you can see, in one root directory there are multiple folders with the same name. What should I do?

Should I create a new root directory?

P.S. With this new version of MiKTeX I figured out that "C:\localtexmf" was not in "Settings -> Directories -> Path". Should I add it (again, but this time in the newer version of MiKTeX)?

manooooh

6:24 AM

(Mental note: remember that everything is concentrated in MiKTeX console, to access go to "C:\Program Files\MiKTeX 2.9\miktex\bin\x64\miktex-console_admin")

Kurt

@manooooh Have you checked after clicking of packages that there are tikz packages and pgfplot listed? If not I guess you have a basic installation. I sugest to do a complete installation with the netinstaller from the MiKTeX Homepage ...

@manooooh You do not need to create/use a localtexmf! Use the possibility of the package manager, now included in MiKTeX Console (you need to click on "Packages")!

manooooh

@Kurt oh, what a fool I am, if the button was there why I did not press it! Yes, there is an "pgfplots" and several "tikz". I just updated "pgfplots" and I am compiling the document, please wait

Kurt

@manooooh or simply call it in the apps of windows (click on windows start in task line)

manooooh

@Kurt oh, that is good to know, many thanks! I haven't touch any MiKTeX config since months (I didn't know about "MiKTeX Console")

@Kurt nope, there is still the message that "1.16" is unkown :/. I clicked on "pgfplots -> Update package database" (it took ~1 min), is it right or should I clicked first on "Install package" (which would be absurd since I use it often)?

manooooh

6:47 AM

Well I am installing it

Kurt

@manooooh Where do you have this version 1.16 from? On my system I get the following list of used files:

 *File List*
 article.cls    2018/09/03 v1.4i Standard LaTeX document class

@manooooh I see version: tikz.sty 2019/02/02 v3.1.1 (3.1.1)

manooooh

@Kurt I have already "install" the "pgfplots" package but I compile the document again and the error message still appearing :(:

@Kurt how did you get that list of used files?

@Kurt where did you see it?

Kurt

@manooooh That is exactly the information I have on my system!

manooooh

@Kurt oh! But I compiled the document after the installation and it still appearing: "! Package pgfplots Error: Sorry, 'compat=1.16' is unknown in this context. Please use at most 'compat=1.15'."

Kurt

@manooooh I added command \listfiles as first line of code into a TiKZ tex code. In the log file at the end I get then the list of used packages and version numbers ...

mickep

6:55 AM

@manooooh ohh, context!

manooooh

@mickep what do you mean? O.o Yes I think I do not have installed the last version of pgfplots

mickep

@manooooh Sorry, I'm just fooling around.

manooooh

Oh, hahah, "ConTeXt" maybe? :P

Kurt

@manooooh Ah, you mean compat. Well, try to add option compat=1.15

manooooh

@Kurt for a graph I need compat=1.16. I am compiling the document with "\listfiles"

I have this:

*File List*

Kurt

7:00 AM

@manooooh Well, I sugest then you ask a question on the main page, that we can see the complete code and play with it. Usually you can set versions with \pgfplotsset{compat=1.15} ...

@manooooh I see no problem here!

manooooh

@Kurt yes yes, I realized that I can actually run the code using 1.15 ... this is very weird since I have compiled this MWE with 1.15 and there is no problem!: tex.stackexchange.com/a/476859/152550 (which is based on this other answer: tex.stackexchange.com/a/476772/152550)

@marmot said that the document must run into 1.16 but the plot is the same if I use 1.15. You lied to all the users? :P

Thanks for your huge help @Kurt!

Kurt

@manooooh You are welcome!

@manooooh I tested it on my computer. With 1.15 or 1.16 I have no problems, with version number I see problems (see red circle):

manooooh

7:16 AM

@Kurt oh, you are right. It misplaces some things. So @marmot wasn't wrong, was me

Kurt

@manooooh Sorry, I ment without version number, not with ... Yes, I recognized that the image was shift to the right while testing the different numbers and none and looked for the reason ...

manooooh

7:33 AM

Okay. I have run the document and I need more capacity

After reading this excellent answer from @UlrikeFischer:

A: How to increase pool size in MiKTeX 2.9

You can use the command line option: pdflatex --pool-size=5000000 .... You can also change the pool size e.g. for pdflatex permanantly: Run on the command line initexmf --edit-config-file pdflatex This will open a local pdflatex.ini in the editor. Add pool_size=4250000 Then save the file...

I end up with:

(and after typing "initexmf --dump=pdflatex"):

On the Build Output of TeXnicCenter:

And since I created a new document and compiled it, the folder containing the .tex, .aux etc. is:

What is happening? The .txt file with the name "pdflatex" which I wrote is:

main_memory=5000000
extra_mem_bot=5000000
font_mem_size=5000000
pool_size=5000000
buf_size=5000000

There are no spurious spaces

The "pdflatex.txt" in it's last lines says:

2019-02-27 04:34:32,632-0300 INFO pdflatex - starting with command line: "C:\Program Files\MiKTeX 2.9\miktex\bin\x64\pdflatex.exe" -max-print-line=120 -interaction=nonstopmode aaaa.tex

I will try this answer:

A: initexmf error -- to increase pdflatex memory

I couldn't find a solution for initexmf errors. Instead I used \tikzset{external/system call= {pdflatex -save-size=80000 -pool-size=10000000 -extra-mem-top=50000000 -extra-mem-bot=10000000 ...

Ulrike Fischer

@manooooh did you check for updates in the user and the admin mode of the console?

manooooh

Before I try that answer I red this: MikTex 2.9 error with pdflatex - no output produced. One of the answers was this one, and when I press "Build format" in MiKTeX console I get this:

@UlrikeFischer by "console" do you mean "cmd" (Windows)? I installed and updated "pgfplots" from MiKTeX Console

And then compiled the document, etc.

Ulrike Fischer

@manooooh no I meant the MiKTeX console.

manooooh

@UlrikeFischer yes, look at this comment: chat.stackexchange.com/transcript/message/49227179#49227179

I am going to try this answer: chat.stackexchange.com/transcript/message/49227659#49227659

No, it does not work either. I paste the code \tikzset{external/system call={...}, compile the document, and still showing the message "Sorry, but ... did not succeed" :(

Ulrike Fischer

7:51 AM

@manooooh in this window (with the admin in the title) check the update button.

manooooh

@UlrikeFischer I think the message "Sorry, but MiKTeX Configuration Utility" did not succeed" is due to there no exist such .exe, since we have to manage everything using the new MiKTeX Console, right?

@UlrikeFischer done (I have clicked on the button that is on the left of the filter and then click on "pgfplots -> Update package database")

I updated it, compiled the document and the error keeps showing up

The "pdflatex.txt" file in it's last lines says:

Ulrike Fischer

@manooooh remove the local ini you created and try again.

manooooh

@UlrikeFischer what do you mean by "remove the local ini you created"?

Btw, thanks for the support!

Ulrike Fischer

@manooooh you wrote above that you did run initexmf edit-config-file to change pdflatex.ini, undo this by deleting the file it opens.

Kurt

8:07 AM

@manooooh Try to compile with LuaLaTeX, it allows more capacity without any other configuration ...

manooooh

@UlrikeFischer do you mean that I have to delete the file "C:\Users\emapr\AppData\Roaming\MiKTeX\2.9\miktex\config\pdflatex"?

@Kurt maybe after I see what I do, now I would like to solve this problem with the help of you. Thanks for the suggestion!

@UlrikeFischer done, I have deleted "pdflatex.ini"

Ulrike Fischer

@manooooh Then try again to recreate the formats.

manooooh

@UlrikeFischer what formats?

Sorry for my lack of knowledge

@UlrikeFischer IT IS COMPILING

@Kurt could you please tell me if with LuaLaTeX I can get a PDF? Also, all the code that I have with using the other format, will it still be the same, or should I change things?

Ulrike Fischer

8:23 AM

@manooooh The problem is not your lack of knowledge but that you click faster than you look. I would say you should spent a bit time to learn the miktex console. Open it and go through the various windows and also through the menus at the top and read what they are showing. Check also the symbols - they have tooltips. Try to find out how to switch between admin and user mode.

manooooh

@UlrikeFischer I have learned a new lesson with this challenge. I will be more careful, because I worry a lot about these things. Thank you, your help has solved my problem

Kurt

@manooooh I compiled the first tex code you linked to without any changings on the code with lualatex, because I got with my first try the error message capacity error when compiling with pdflatex. I never changed capacity configuration, because lualatex does it. And if I do not use very special fonts I can run the same code with lualatex too ... But at last it depends on the used code, of course ...

manooooh

@Kurt I think I will never change of fonts

Kurt

@manooooh Ohh, I`m sure you will, there are some nice fonts out there, for example libertine.

manooooh

@Kurt hm, you are right, I have not written my CV yet (although maybe I use some of those templates that are free there on Internet)

@DavidCarlisle regarding Javier's bug report in hyperref, I think one can expand the hyperref command before passing it to \l@section. But is it sane code from titletoc, if \def\somecontents{XXX}\l@section{\somecontents} breaks because \l@section closes a group opened by a previous \l@subsection before processing \somecontents?

In TikZ, what is the meaning of postaction and preaction

Also, what is the meaning of the code `\draw[thick,red,zigzag,postaction={

},
decorate
}] (-2,0) coordinate(a) -- (2,0) coordinate(b);`

@UlrikeFischer I don't think that sounds right but I haven't looked in detail at the use case that it is trying to address

yo'

@egreg k^{^-1}

Ulrike Fischer

@DavidCarlisle thanks, I only wanted to know if I'm getting over picky ;-). (I think he is somehow trying to decide about some formatting for the subsection entry only when the section entry has started. But I don't know if there aren't better solutions than overlapping groups).

@DavidCarlisle I guess there is no sane way to get overlarge longtables stick in the outer margin in twoside mode?

yo'

@egreg and then obligatory: \begin{figure*}[h!]

David Carlisle

@UlrikeFischer well... I may have done something along those lines once...

@UlrikeFischer is there a miktex texdoc equivalent? tex.stackexchange.com/questions/474752/…

Ulrike Fischer

@DavidCarlisle what does once mean? tex.sx, usenet, your private file collection? (It is not really important, I only saw a question about it and started thinking.)

@DavidCarlisle texdoc usrguide.pdf works fine for me in miktex.

David Carlisle

12:50 PM

@UlrikeFischer "somewhere in the back of my brain" I may only have wondered about doing something, but I think I may have done it. Somewhere:-)

@UlrikeFischer perhaps just not used to using the commandline to type stuff

Ulrike Fischer

@DavidCarlisle probably, but you should ping the guy or he will never see your remark.

David Carlisle

@UlrikeFischer It's there for future reference, he's already found the pdf anyway:-)

egreg

1:23 PM

@yo' Somebody uses a superscript minus sign for negative numbers, though.

Not that I endorse the practice.

Harald Hanche-Olsen

@egreg I have certainly seen (and used) it for the negative part of a number: $x^{-}=-\min(x,0)$. But you're talking about writing $10^{-}$ instead of $-10$, perhaps? Not sure I have ever seen that.

David Carlisle

@HaraldHanche-Olsen At school level in the UK it is common practice to write -10 as ${}^-10$ so that it is easier to distinguish a literal for a negative number from the subtraction operator.

mickep

@egreg, @yo' @HaraldHanche-Olsen while talking about good and bad habits, what do you prefer, $2/7$ or $\frac{2}{7}$ (in inline math mode, that is)?

Harald Hanche-Olsen

@mickep I tend to use the latter. But I avoid $\frac{1}{x}$ and the like, reserving the fractions for numerical fractions involving (mostly) single digit numbers.

mickep

@HaraldHanche-Olsen OK, thanks.

yo'

2:18 PM

@mickep no preference really from me, either works fine. But I'm quite liking slash fractions in general

mickep

2:33 PM

@yo' I also usually use slashed fractions in inline math. However, co-authors do not :)

@Jasper Hi Jasper! Two Inspirons, one Latitude and one Vostro.

And hopefully, until the end of this year, a XPS. :)

@AlanMunn OH MY YES

Jasper

@PauloCereda Aha! Well, @JosephWright has an XPS! =)

@PauloCereda Make sure you get one with the webcam at the top, not at the bottom or the side.

David Carlisle

@AlanMunn you could throw it at the ducks if they get too close

Paulo Cereda

@Jasper lucky ducky. :)

@DavidCarlisle oh no

Jasper

@PauloCereda It seems that Dell sells computers cheaply in the US but more expensively outside US.

Paulo Cereda

@Jasper actually, it wouldn't make a difference for me, since I do not use webcams. :) Also, once you have a machine with an integrated iSight, every other camera looks cheap. :)

@Jasper Probably, but I think their hardware to be the best available, given our options.

Jasper

3:49 PM

@PauloCereda Actually, I think HP might be better than Dell in some ways. I know HP has some very good and affordable models.

Paulo Cereda

@Jasper My dad has an HP, entry model. I personally do not like it, but it's a matter of taste.

In here, I think the middle ground is Acer.

Jasper

@PauloCereda I got an Acer Swift 3 last year, but the backlight of the keyboard does not work as expected. It goes off after 30 seconds until you press another key. So avoid that if the backlight is important to you.

Paulo Cereda

@Jasper it isn't. :) Did you check your BIOS setup? Maybe there's something there.

Jasper

@PauloCereda Looked through all settings. Don't think any setting can change the backlight behaviour.

CarLaTeX

6:23 PM

@egreg Yes! I noticed that! Lol

Skillmon

Today I tried to compile a class of mine using XeLaTeX (which I thought had worked previously). I'm getting the error message Package fontspec Error: The font "TeX Gyre Heros" cannot be found. with kpathsea:make_tex: Invalid filename TeX Gyre Heros', contains ' '` previously...

It works under LuaLaTeX.

Ulrike Fischer

@Skillmon Does it work if you use \setmainfont{texgyreheros-regular.otf} instead of \setmainfont{TeX Gyre Heros}?

Skillmon

@UlrikeFischer yes, that works in both engines. Thank you very much! Why doesn't it work in XeLaTeX though?

Ulrike Fischer

@Skillmon I assume that you have linux, and you can't use font by names from the texmf tree unless you add the tree to your fontconfig. See e.g. tex.stackexchange.com/a/257232/2388

Skillmon

@UlrikeFischer that seems to be the case. Do you know how to find the .otf replacements for font names (so that I don't have to bother you every time)?

Ulrike Fischer

6:33 PM

@Skillmon I compile in this cases with lualatex and then look in the log.

Skillmon

@UlrikeFischer that seems a very intelligent solution :)

Ulrike Fischer

@Skillmon ;-) sometimes I have good ideas ;-).

Paulo Cereda

@UlrikeFischer ooh

egreg

@HaraldHanche-Olsen No, something like ${}^{-}1$ . Somebody thinks it helps kids to understand negative numbers. I heartily disagree.

Skillmon

@UlrikeFischer I never doubted it!

Ulrike Fischer

7:11 PM

@DavidCarlisle do you think we can do something about this tex.stackexchange.com/a/476742/2388 in the kernel? microtype uses a function which without luatexbase doesn't do what it is supposed to do.

local err, warn, info, log = luatexbase.provides_module(microtype.module)
microtype.warning = warn

David Carlisle

@UlrikeFischer not really, we could of course have kept that provides_module interface returning the warning functions when luatexbase was incorporated as ltluatex but we (@JosephWright and me, I guess) decided not to, so it wouldn't really be consistent to change now, just because microtype didn't update., I haven't looked at the microtype code but is it possible to add a lua definition of microtype.warning after loading the package or is this a private table?

@UlrikeFischer oh as you have posted, loading luatexbase is easier, yes

Ulrike Fischer

@DavidCarlisle the error is already during loading the package/lua code: microtype detects that a luaotfload function is now defined and wants to warn about it:

if luaotfload.letterspace.keepligature then
    microtype.warning("overwriting function `keepligature'")
  end

@DavidCarlisle yes, but as you can see from the comments, people don't like this ;-(.

David Carlisle

@UlrikeFischer tough

@UlrikeFischer actually if they are moaning about the tl18 freeze but that would apply as much to any change we make as any change in microtype

@UlrikeFischer are the definitions actually compatible or are loaotfload and microtype tying to give different functions the same name?

Ulrike Fischer

7:28 PM

@DavidCarlisle which one? luaotfload.letterspace.keepligature? that's a documented interface to influence the ligature handling during letterspacing. So it is more or less okay that microtype overwrites it (and it does it in a sensible way). The only problem is that the warning message gives an lua error.

@UlrikeFischer oh OK the warning is just a microtype bug (or you could say that microtype has a dependency on luatexbase) I just wondered if the actual redefinition was OK, sounds like it.

Ulrike Fischer

@DavidCarlisle I'm not sure if the function was a good idea - if only one package defines it, it is ok, but with more package it could easily give a mess. We actually considered to remove it, it is much more sensible to set the ligatures through the font options, but then we discovered that microtype uses it and so had to keep it.

@DavidCarlisle good edit ;-)
