Thanks, still learning my way around

@DavidCarlisle Thanks! works for gag purposes!

Does anyone here know the rgb value that would best approximate mimeograph purple? I'm getting nowhere with google.

@UlrikeFischer In my case, slides means "article" :-)

Thanks for the help. I'm going to try to make using alt text a habit when I start making slides again in the Fall.

@mickep Helps if I save my editor buffer :-). What's the encoding, do you know?

I see this: << /Type /StructElem /Alt <FEFF005400680069007300200069007300200061006C007400650072006E00610074006500200074006500780074> /S /Figure /P 15 0 R /A <</O/Layout/BBox [148.71233 354.18755 548.71135 654.18682]>> /K <</Type /MCR /Pg 22 0 R /MCID 1>> /ID (ID.009) >>

Ooh, maybe it is, but still compressed or perhaps encoded: "FEFF005400680069007300200069007300200061006C007400650072006E00610074006500200074006500780074"

@DavidCarlisle Thanks, uncompress certainly worked, the .pdf is 6x bigger, and the .png is a visibly different image. But if the alt text is there, 'strings' still doesn't find it.
dedded
May 11, 2024 19:59
@JosephWright Do you know if strings should have found it?

I just attempted to add alt text to an image with `\DocumentMetadata{testphase=phase-III}` and `\includegraphics[alt={This is alternate text}]{example-image}`.

Is there any way for me to test the result? I'm on a mac. I couldn't find anything with `strings foo.pdf | grep alternate`

@UlrikeFischer OK, thanks!

OK, I saw this (\AddToDocumentProperties[hyperref]{pdftitle}{#1}) in code I was poking around in to see if I could specify anything other than author and title for the pdf info, and it made me wonder.
dedded
Mar 16, 2024 21:10
Does specifying \DocumentMetadata{testphase=title} trigger an automatic loading of hyperref?

Does anyone else do slides in class article? Every couple of years or so I start looking at the docs to Beamer, decide no, and go back to article.

Feb 25, 2024 13:39
@DavidCarlisle It's fontspec.sty
dedded
Feb 25, 2024 13:34
So I wonder if another package loads it.
dedded
Feb 25, 2024 13:32
Still see this in my log files:
`Package: xparse 2024-02-18 L3 Experimental document command parser`
I can't find anywhere that I explicitly load the package.

@JosephWright Ah, I figured that was the difference between lualatex and luatex, but I always thought that ...-dev referred to a new engine.
dedded
Feb 23, 2024 03:21
Just noticed that lualatex and lualatex-dev are both symlinks to luahbtex. Are they then identical?
dedded
Feb 17, 2024 01:57
@UlrikeFischer All this mention of dvilualatex, so I ran man dvilualatex to see what it was. I noticed that tlc2 is recommended at the bottom of the page. Have you guys updated that to tlc3 for tl2024? The page is dated 2018, so it looks like something that might not be regularly considered.

I use a hacked copy of `\changefontsizes` from scrextend.sty to change font sizes. I knew this would eventually get me in trouble, since my copy doesn't get any updates that are made to that command in scrextend. And I finally ran into that trouble yesterday when `\MakeLowercase{\large ...}` went into an infinite loop. So I had to re-construct my hacked copy.

Would the scrextend team be open to an enhancement request? My hack is pretty simple, I just replace hard-coded constants with a command, so for example I make this replacement for `large`:

That's how I did run it, from a terminal. The error was still a pop-up.

@MarcelKrüger Pre-built ones

@MarcelKrüger Apologies, but I didn't get too far with the install. l3build moved the lua/sty files to my .../tex/luametatex area, but I didn't get anywhere with the binaries.

@TeXnician Thanks, I'll try to play with that tonight.

I'm on a Mac, but have the command-line subset of Xtools.
Is there a build script? Actually, is there a link? You mention a README.
dedded
Oct 19, 2022 00:20
@MarcelKrüger I could run it against the documents I've made over the last year or two. Would the setup be v. involved? (I'm assuming a Latex interface, not Context. Is that the case?)

@mickep In 2020 (June) Springer put a number of their books up as free .pdfs. Unfortunately I don't recall the notice and url. Perhaps this was among them (?).

@UlrikeFischer I would very much like to see this. I have to work around it (by creating an extra font family) in some documents. Makes a difference of minutes vs. seconds.
dedded
Mar 2, 2022 19:10
@JosephWright I'm likely missing some context here, but are you asking for any document where lualatex is 10x slower than pdflatex? If so, I think I have one, but it's been months since I've tried it. It's not a normal document, but if I recall correctly lualatex took about 2.5 minutes and pdflatex was on the order of 20-30 seconds or so. I can check if I'm misremembering tonight if there is interest.

I suppose now's not the time to mention that I've had math at a university (and am married to a math prof.). When I saw it I thought I was missing a movie reference or something.

Speedy recovery indeed! But I've got to ask, what is "epsilon speed"?
dedded
Feb 15, 2022 16:25
@mickep I know it's a standard (from Latex discussions). But standardized ugliness is still ugly. :-) Still, thanks for the pointer, I'm curious to read about it. And @barbarabeeton I agree that italic d isn't great in stix2 (the glyph is too fat, too). It will be my luck that the US will adopt this ugly upright-d standard and still leave everyday SI adoption languishing.
dedded
Feb 15, 2022 15:57
@barbarabeeton "italic d as the differential", yeah, my practice too, and in all my old textbooks. In fact, I've only ever seen upright d as diff in Latex discussions (and personally find it jarringly ugly).

Feb 15, 2022 13:45
@mickep That's a good thought, I'll look into it tonight. Suppose I'll have to create a github account.

I don't think I ever used f as a variable in a math test. Most likely only ever used it as the "name" of a function f(x) ...

@DavidCarlisle I'm not sure what you mean, but it sounds like way beyond my latex skillset.
