@Alucard That's the Dynamic at the end. @Szabolcs maybe ImageSizeRaw would be better than ImageSize for that? In any case I only have a retina screen so can't be helpful here.

@Szabolcs Looks OK on Linux with WQHD resolution, although imo the level of detail is too high and is not resemble its beauty on this small size

What helps a bit on my machine is a) using an absolute thickness of 1 for the lines and more importantly b) use colors where you fixed the brightness so that you are sure you have enough contrast between gray lines and colored regions.

This looks clearer to me:

I increased the size of the colored regions a bit and made the black disks a bit larger.

is there a reason why Exclusions doesn't work with ListPlot?

@halirutan That looks much better!

It's intended for a summary box icon, that's why it's small. @Alucard

@Szabolcs szabolcs can you explain me how to make the grey line in the comment section ? there are no buttons like for the answers

@Alucard I don't know what you mean by grey line.

You can use Markdown for formatting, as usual.

I have heavily re-written this question after providing an answer, that was ultimately accepted while I was editing. Did I over did it? I think the OP does deserve another answer explaining why he didn't get a ConditionalExpression, but I do not know the answer to that. Help! Looking for advise Please revert if necesary.

@Szabolcs I'm glad you like it.

What is the point of MakeSummaryItem? It seems to be defined as SummaryItem anyway, and most builtin packages use SummaryItem instead.

Does anyone have an example of a builtin summary box that uses the 3rd argument of SummaryItem? I can see how it formats, but I would like to see it in actual use.

@Szabolcs - you're right, MakeSummaryItem is deprecated, use SummaryItem instead

@halirutan If you want to chat about expreduce then I have some insight, having made one commit and working on another. As you say in your post, it may make sense to prioritize certain things. But the way it's built it's perfectly possible for each developer to implement the features he'd like to see.

@C.E. I inspected your commit when it was merged :)

@halirutan just posted on the github issue

weirdly enough, CopyToClipboard["test"] doesn't copy to clipboard, it just empties it =/

@halirutan ah, ok. Then you know that I'm working on implementing functional operators. That's still what I'm doing.

I tried Unprotecting $VersionNumber but it didn't like it none

@EmilioPisanty No, just use the code example and use $VersionNumber > 10 instead of >=

We need to find out, why CopyToClipboard is not working on your machine.

@halirutan yeah, that does work, as does just taking the bits inside the module

@halirutan and yeah, that's the really weird bit

@EmilioPisanty Oh, then this is really weird

@EmilioPisanty OK, let me read you answer

@EmilioPisanty You say that:

> I tested the given copyToClipboard but all it does is empty the clipboard - but then, that's what CopyToClipboard does,

@halirutan yeah, the issue is the built-in, not your wrapper

So you say that the built-in function CopyToClipboard does not work in your installation.

@halirutan yup

if I have text in the clipboard and then run it then that text'll be gone, but that's all it does

I'm at a loss as to how to diagnose it further

@EmilioPisanty So the following function should work:

ClearAll[copyToClipboard];
copyToClipboard[text_] := If[
   $VersionNumber >= 11,
   CopyToClipboard[text],
   Module[{nb}, nb = NotebookCreate[Visible -> False];
    NotebookWrite[nb, Cell[text, "Input"]];
    SelectionMove[nb, All, Notebook];
    FrontEndTokenExecute[nb, "Copy"];
    NotebookClose[nb];]
   ];

@halirutan yeah, that works

but I can't test on other v10 machines to check that that doesn't break stuff

@EmilioPisanty You can easily fix your local Uploader.

@halirutan sure, just don't push stuff that might break other people's palettes

where do I need to edit?

@EmilioPisanty I tested the CopyToClipboard with all versions I had available and since it worked on 10.3 and was available on 10 in general, I included this condition.

@EmilioPisanty The package is usually in your $UserBaseDirectory under Applications

Close Mathematica and open the file SETools/FrontEnd/Palettes/SEUploader.nb with a file editor

Search for copyToClipboard and replace $VersionNumber >= 10 with $VersionNumber >= 11 in its definition.

@halirutan ah, I was editing SEUploader.m directly

@EmilioPisanty Nope, that's the source code. You can do this as well! But then you need to open the palette by loading this .m and save the palette manually.

bingo

thanks a bunch :)

@EmilioPisanty See, the mole was benign and you waited several month :)

@halirutan well, it's not like it was entirely irreplaceable

it saves a lot of hassle but you can save to disk then upload

I guess on most occasions I was too busy and the hassle of starting an issue was ever so slightly bigger than just saving to disk

@EmilioPisanty Hehe.. yes, I know how this feels.

FE crash, V11.2, MacOS, while double-clicking....

Hey @Szabolcs, before I do a deep dive, is it pointless to try and get MaTeX to play with lualatex and fontspec?

OK, no, first hurdle cleared

second question

my MWE relies on fontspec and needs the truetype fonts to be available to lualatex

is there a way to get MaTeX to add that to the path or something?

@MichaelE2 - can you send in the crash report for that? I've had various FE crashes in 11.2, but to my knowledge they haven't isolated it yet

Hi @EmilioPisanty

@Szabolcs hi

so I'm still stuck with this

I reckon there's a problem with my TeX installation

I don't use luatex, but I did test it, and it does work with MaTeX. There was one little problem which is discussed in the troubleshooting section (and I don't remember it so you have to check!)

in that it's not handling correctly files that call fonts from outside the current directory

but, if there is a way to copy the fonts into the temporary MaTeX directory, then I'm happy to call that a day

Can you give me a small example?

Did you use the luatex85 package? My notes say that might be needed ...

@Emilio ^

This is a font installed system-wide.

How do you set the font path with luatex?

@Szabolcs here's a MWE .tex

\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage{fontspec}
\usepackage[helvet]{sfmath}

\setmainfont{swiss.ttf}[
   Path = /home/episanty/Desktop/Font/ ,
   BoldFont = swissb.ttf ,
   ItalicFont = swissi.ttf ,
   BoldItalicFont = swissbi.ttf
 ]

\begin{document}
$$\Omega/\omega$$

$$\mathbf D_\mathrm{R}(\Omega)\ \mathrm{(arb.u.)}$$
\end{document}

Where do I get that Swiss font?

@Szabolcs yeah, that's the question

@Szabolcs I'm not sure

I got it from work

OK, I'm going to try this fontsquirrel.com/fonts/signika

@Szabolcs I'm not sure what implications could come from a switch from .ttf to .otf

Works, kind of

But freaks out with certain character combinations

E.g. I can't typeset "Signika"

I don't have experience with this, so I'm not sure what is wrong.

@Emilio can you send me then font then?

Dropbox or something.

@Szabolcs dropbox.com/sh/u229036qxjx8een/AAC2mB1sH9oMuRhASJ6q7xq2a?dl=0

This isn't a MaTeX problem though, is it?

ping me when you got it

@Szabolcs I don't know

I can get lualatex test.tex to produce the right output now

but if I copy the preamble into MaTeX and run it on the body, the font is wrong

and, if I get the TeX via TeXFileFunction and then lualatex that, then the font is wrong again

@Emilio It seems to work here ... is this the expected output?

I have MacTeX 2017, which is AFAIK the same as TeX Live 2017

@Szabolcs I think I'm on texlive 2015

maybe that's the problem?

god, I hope that's not it

Sorry, I really don't know.

Does it work with xelatex? Do you actually need lualatex?

@Szabolcs that looks correct and I get the same on MaTeX

@Szabolcs yes, xelatex is incompatible with baposter.cls

I have luatex 1.0.4, if it matters

@EmilioPisanty OK, so can you show an example that doesn't work?

\setmainfont doesn't set the math font, if that's what you meant by getting the wrong font

But my LaTeX knowledge is really limited, to be honest, despite what people tend to assume ...

@Szabolcs $|\mathbf D_\mathrm{R}(\Omega)|^2\ \mathrm{(arb.u.)}$

the \Omega is way off

no blame on MaTeX btw

With this preamble, the \Omega stays in Computer Modern because \setmainfont only sets the text font

there's just something weird going on

Well, you used \usepackage[helvet]{sfmath}, so you get that kind of Ω

\documentclass{article}
\usepackage{amsmath,amssymb}
\usepackage{fontspec}
\usepackage[helvet]{sfmath}

\setmainfont{swiss.ttf}[
   Path = /home/episanty/Desktop/Font/ ,
   BoldFont = swissb.ttf ,
   ItalicFont = swissi.ttf ,
   BoldItalicFont = swissbi.ttf
 ]



\begin{document}
$$\Omega/\omega$$

$$\mathbf D_\mathrm{R}(\Omega)\ \mathrm{(arb.u.)}$$
\end{document}

this, under lualatex, produces the \Omega marked as 'goal'

Math and text fonts are set separately, and normal fonts can't be used for math. You need special math fonts, of which there aren't many available. There's the Latin Modern ones, STIX and Cambria Math, that I know of

ah, got it

so

I set TexFileFunction->Print and copied that to file

I don't know why you would get "goal" since you used sfmath ...

then removing \usepackage{lmodern} did the change

@Szabolcs yeah, I'm not sure what's going on into what fonts get there, but that's the combination that looks least ugly ;-)

Hah

yes

Some incompatibility between sfmath and fontspec?

removing lmodern from "BasePreamble" makes MaTeX work

@Szabolcs mostly, there's no need for lmodern if you've got fontspec there

you put it in for arbitrary font sizes, right?

@EmilioPisanty Yes.

@Szabolcs thats pdflatex?

On some systems it is necessary to have vector fonts. Otherwise it uses bitmap which can't be imported to Mma.

lualatex

odd

If I uncomment the fontspec line, it reverts to CM fonts

@Szabolcs ¯\ _(ツ)_/¯

I've been on "whatever works" mode for some time

=)

Here it says that fontspec must be loaded after sfmath

So it would seem that 1. fontspec must be loaded after sfmath, 2. use the no-math option so it wouldn't mess with math fonts 3. the "goal" version is really not what it it supposed to look like. You seem to want CM font Greek letters in math mode and sfmath-style Roman math letters

It's late though and I should sleep

Let's contiue tomoorrow

Goodnight!

@Szabolcs 'night

@JasonB. Do you mean the MacOS system diagnostic report? [All I can report personally is that double clicking on a number in an input cell was followed by a crash. Do you think it's worth it? (It was extemporaneous fiddling around, so no code, no notebook to submit. I can't reproduce it)]
