Hello guys, is there a math font "switcher" for \mathrm{} as for example \textrm and \rmfamily?
 
9:42 AM
@WillRobertson Seen the latest Lua work we are doing? :)
@WillRobertson Makes me want to re-write l3build ;)
 
@JosephWright I learned a new word "entires" ;-)
 
@UlrikeFischer Fixed: does show why auto-generation of the man file is a good plan
 
@Richard yes or no, depending on how you view it , \mathrm is \DeclareSymbolFontAlphabet{\mathrm} {operators} so if you change the operators font, which by default is \DeclareSymbolFont{operators} {OT1}{cmr} {m}{n} then mathrm will change, but other stuff will change too.... eg $123$ digits come from there by default
 
@WillRobertson, @UlrikeFischer Comments on license on team list most welcome ...
 
@UlrikeFischer I noticed that but forgot to mention it to @JosephWright
 
9:50 AM
@DavidCarlisle :)
 
@JosephWright the oracle claimed that the word exists ....
 
@UlrikeFischer that's entirely reasonable
 
@UlrikeFischer Well yes but clearly a typo here :)
 
@JosephWright if you use a language where all the words are 50 letters long you can't accidentally get another valid word by making a typo in a different word

@DavidCarlisle ^^^
 
9:57 AM
@UlrikeFischer dinner
 
@UlrikeFischer A DUCK!
 
In l3fp, \@@_tuple_convert:Nw uses \@@_array_count:n. Is a tuple internally represented as array? Or are these different things?
There is also l3fparray but I assume that this is really something different ...
 
10:36 AM
@JosephWright [...] syntax not supported in globs! :(
 
@DavidCarlisle Indeed
@JasperHabicht That's using font dimens for global storage
 
@JosephWright I wanted to list all files not ending in ~ , *[a-z] or *[^~] would work (and be easy to turn into lua patterns, probably)
 
11:04 AM
@DavidCarlisle We could add it: I skipped it in l3build as it feels total alien to me
 
@JosephWright in what way is it alien? I guess I use [...] almost all the time when listing files
 
@DavidCarlisle Remember I have a Windows background ... so to me command line wildcards are strictly * and ?
 
@JosephWright which is why I never use the useless windows command line:-)
 
@DavidCarlisle Difference of mindset: if I want to do that, I'd expect to need a script using a loop and comparison
for %I in (*.txt) do , etc.
 
@JosephWright well exactly but I want .txt .1 .lua .tex and .anything not ending in ~
 
11:12 AM
@DavidCarlisle Key for l3build was meant to be cross-platform consistency, and for a Windows user, [..] does look like that to me
@DavidCarlisle :)
@DavidCarlisle I always find that really odd, as it adds the ~ to the extension not the name :(
 
@JosephWright windows users should be using powershell or wsl by now (I know they don't, but they should)
 
@DavidCarlisle Like I said, no issue adding it really - it's just a question of presentation
@DavidCarlisle We've talked about that :)
 
@JosephWright there is no extension there is just a dot in the name
 
@DavidCarlisle :)
@DavidCarlisle I refer the honourable gentleman to my earlier answer
 
11:57 AM
@JosephWright ORDAHHH

@JasperHabicht Submitted a PR to improve the README.md :) -- github.com/cpierquet/vectorlogos/pull/1

@koppor Do you need a true vector version of the logo or just an svg which has the pixel graphic embedded?

6:30 PM
@DavidCarlisle I looked a bit. Are there any fonts to download somewhere or do I need to compile?
 
6:47 PM
@mickep yes you can get it from a zip file hang on I'll get the link again..
@mickep ooh that PR has been merged khaled's branch where I got it has thus been deleted so it should be at ...
 
@DavidCarlisle Ah, thanks, I think I found something.
Under Actions.
 
I used proof.zip from khaled's fork for an action ran yesterday but that's been cleaned up since it was merged
@mickep ah this page has updated itself and I suppose is the official page notofonts.github.io/math
 
@DavidCarlisle Good! I wonder why there is a specific one for google fonts.
 
@mickep I don't know if they inject different metadata into the gfonts version, I didn't look

Achievement unlocked. Yesterday I learned how to customize BEAMER to use our NSF grant's official branding as a background.

How can I make \__pdf_backend_bdc:nn {Span} {/ActualText(Foo)} work properly? If I use theaccsupp package and inspect the PDF, I see that /Span /ActualText(Foo) is inserted right before the relevant box in the PDF and the screen reader reads the "Foo". But with \__pdf_backend_bdc:nn, things are put into the header of the PDF and the screen reader seems to ignores it.
 
@JasperHabicht you shouldn't use it, that's an internal command. There are user command in the pdfmanagement. What are you trying to achieve?
 
@UlrikeFischer Hm, yes, I know its internal. I want to create a \Span to assign an ActualText to a picture, but I could only find \pdf_object_unnamed_write:nn which I think I can't use for this?
 
10:31 PM
@JasperHabicht like this:
\DocumentMetadata{uncompress}
\documentclass{book}
\usepackage{graphicx}
\begin{document}
\ExplSyntaxOn
\pdf_bdc:nn{Span}{/ActualText~(blub)}
\ExplSyntaxOff
\includegraphics{example-image}
\ExplSyntaxOn
\pdf_emc:
\ExplSyntaxOff
\end{document}
but you will have to handle the encoding of the string yourself (accsupp would do that for you).
 
10:43 PM
@UlrikeFischer Hmmm ... but Acrobat Pro's own reading tool just says "image". But it does that when I use accsupp as well ... I am a bit confused because it worked before
I have to do more tests ...
But thank you anyways. At least I know now how I should to it. =)
 
@JasperHabicht works for me with my example. Acrobat reads "blub". Or wait. I think I activated tagging in between. Need to test again without it.
@JasperHabicht you are right without tagging Acrobat ignores the ActualText for reading (it does use it for copy&paste).
 
@UlrikeFischer But it does not work with accsupp either. I can't reproduce why I first thought that it would
@UlrikeFischer Copy/paste would also great, but you can't select a picture, so you can't copy it, or can you?
 
11:12 PM
Cool! With testphase=phase-II it indeed works. Nice!
