@Skillmon Setting environment variables as I would in a Makefile or a shell script, say.
12:15 AM
@DavidCarlisle Thanks. I don't understand it, but I will try to figure it out.
2 hours later…
2:38 AM
@PauloCereda Yes, it is! But he's usually called only Paperino.

7:29 AM
Apparently there was a css bug in github, through errors in mathjax? And YouTubers keep says in was problems in LaTeX code ...
@daleif ?
@mickep why write a blog rather than simply reporting it to mathjax so it gets fixed? (not you, but them)
@DavidCarlisle I don't know. Maybe they did both? Haven't we seen that before? :)
@daleif Can't see where the LaTeX angle comes in at all ...
7:42 AM
The YT video I saw kapt saying it was becauise of LaTeX parsing of blah blah commands. No it not, there is LaTeX there.
@daleif Oh, I see: conflating LaTeX and MathJax
My issue was that they kept refering to mathjax as LaTeX. We know better
@JosephWright exactly
@daleif On a train right now: will watch later
@JosephWright It is not super relevant. Just that he does not have his facts correct. Yes there are issues in the mathjax js code, but it is not latex.
So don't keep refering to it like that.
@daleif I agree completely. I wonder if this is a problem for the LaTeX -> HTML/mathml/mathjax documents used for arXiv, for example, though.
(maybe not this issue...)
7:59 AM
The issue is fixed in mathjax v4 beta (and has been reported multiple times on mathjax list...)
@daleif It's not relevant to the LaTeX code, but it should be relevant to the LaTeX community :) (and btw, it caused a security call in Overleaf, as we use MathJaX of course)
3 hours later…
11:26 AM
@UlrikeFischer you saved me from looking up the doc to get the section number
11:40 AM
@DavidCarlisle ;-)
@DavidCarlisle I wished the reference had an index ...
11:55 AM
New GitKraken feature: I can see which PRs I have open, etc., and which have merge conflicts - so keeping them all up-to-date :)
1 hour later…
1:05 PM
@egreg @CarLaTeX, today my lunch was cold pizza Hawaii. Is this better or worse than fresh pizza Hawaii?

@Skillmon it's a matter of correct labelling ;-P
1:47 PM
Oh, monthly ConTeXt online meeting tonight at 7pm (CEST) at lecture.senfcall.de/hen-rbr-rku-oke.
@Skillmon I'd say worse :D
@Rmano lol
@Rmano lol
@Rmano thankfully I don't see any pizza di anatra
@Rmano oh no
2:42 PM
Is it safe to alter the order of execution in shipout/background?
A: Title page background opacity issue with TikZ

cfrThis is not the correct way to use shipout/background. It may happen to work, but it's not the method documented in ltshipout-doc. The hook expects commands valid inside a picture environment. However, the opacity is incorrect with XeTeX regardless. If your example reflects your actual usage, you...

2:53 PM
@cfr yes, and it is needed (with xetex). pgf doesn't add the backend support needed for opacity otherwise.
3:16 PM
I exceeded TeX capacity while building my documentation with l3build doc :(. However, the documentation successfully builds if I run LaTeX on the dtx file directly without using l3build. What does l3build do when building documentation?
@DavidPurton hi mr. koala!
@PauloCereda Hi!
@DavidPurton is the code available somewhere?
@UlrikeFischer I can push to Github. But I'm pretty sure it's my fault. It happens in connection with code that combines redefining \par and \peek operations…
@DavidPurton sure, but it is easier to get an idea if you are not only relying on the crystal ball but can see what is happening.
3:26 PM
I will push
@DavidPurton are you running LuaTeX on the command line?
both l3build doc and manual build is lua
@DavidPurton and sent a link ...
@DavidPurton how sure are you that l3build runs using LuaTeX?
@Skillmon Very sure. The documentation is filled with fontspec commands and things that only work with LuaTeX
3:28 PM
@DavidPurton in that case this is the end of my crystal ball :)
(Please try not to judge my code too much…)
I'm regretting trying to add this feature.
@DavidPurton it doesn't compile because of missing fonts for me ;-(
@DavidPurton Font "Kawkab Mono Regular" not found. but we'll see if that matters...
Ah - yes
apart from that it gets to the end and says Output written on scripture.pdf (79 pages, 712041 bytes).
3:34 PM
@DavidPurton when you run outside l3build do you use an installed package or the current build
My system is not quite up to date (Debian testing hasn't updated for a while)
That font is just a fixed width Arabic font
@DavidCarlisle I replaced the font with Amiri, but now it hangs at page 16 ...
Yes, page 16 is problem for me too
Do you get success if you run lualatex on scripture.dtx?
@DavidPurton @UlrikeFischer with amiri l3build doc works with no errors
Output written on scripture.pdf (93 pages, 1012109 bytes).
3:42 PM
@DavidPurton no it errors starting with page 11 The key 'scripture/chapter/para' is unknown
@UlrikeFischer oh I get that, why doesm't l3build doc stop there....
Weird. That shouldn't happen
@UlrikeFischer @DavidPurton that's what you get if you typeset the new dtx with the installed tl2024 version of the package
@UlrikeFischer try tex scripture.ins first
@DavidCarlisle Oh - that makes sense. The version in TeXLive is not updated for a while
I also made that mistake (but with different version of sty file).
If I use the sty file produced by tex scripture.ins. Then lualatex scripture.dtx fails for me :(
@DavidPurton that's why I was asking this as my crystall ball was suggesting that might be the difference when using l3build (which always uses the current siurce version)
3:49 PM
strange that you can build though…
@DavidCarlisle Sorry I missed that. Your crystal ball is good
@DavidPurton better than my spelling/typing, at least
@DavidCarlisle now it doesn't error but again hangs at page 16.
I can't seem to make a more minimal example that fails unfortunately.
@DavidPurton do you have any of the fonts haranoaji ipaex installed outside texlive
:65790828 yes.
fc-list | grep IPAMincho
/usr/share/fonts/opentype/ipafont-mincho/ipam.ttf: IPAMincho,IPA明朝:style=Regular
3:57 PM
@DavidPurton bingo
Why does that cause trouble?
@DavidPurton well it depends, you pick up a possibly older font(9and sometimes you pick up type1 really old fonts that don;t work at all or ...0 anyway it's a difference from my system where I get no error and fv-list shows:
$ fc-list | grep IPAMincho
/usr/local/texlive/2024/texmf-dist/fonts/truetype/public/ipaex/ipam.ttf: IPAMincho,IPA明朝:style=Regular
so hiding the font in /usr/share might be worth a try, oh unless your system supplied tex puts all its fonts there and not in the tex tree?
hmmm. Well, I admit that it is to do with language set up. If I remove babel and the foreign language examples, then it builds.
@DavidCarlisle The fonts in Debian can be in both the TeX tree and system font location
Frustratingly, the main branch (which has the same language set up) builds fine.
@UlrikeFischer Thanks.
@DavidPurton yes same here but if the same one is in both it's not well defined which one gets used so can lead to things working on one machine and not others
4:16 PM
Sigh. It's late. I'll come back to it some other time.
Thanks for help @DavidCarlisle
4:41 PM
@DavidCarlisle l3build seems to add to search paths? I half-figured out what some of the syntax means, but maybe not the significant half.
os_setenv .. " TEXINPUTS=." .. localtexmf()
.. (checksearch and os_pathsep or "")
.. os_concat ..
lua.org/pil/2.4.html says .. is the string concatenation operator, but then I don't know what it is doing at the start and the end.
@cfr yes unless checksearch is true it sets the search path to only look locally (so we can test latex base without it picking up contrib stuff)
5:03 PM
@DavidCarlisle So there isn't an out-of-the-box way to do something in between? What I'd like to do is to tell it to search locally and in the distribution tree, but I don't want it using stuff from any other tree. But that means I need to override the settings in the two texmf.cnf in the distribution tree. (At least, I think it means I need to do that?) One is the TL one and the other is mine. But those work cumulatively, I think, so I can't just drop a replacement into the working directory?
5:48 PM
@cfr not sure I understand but if you set TEXINPUTS in the environment or in a local texmf.cnf you have full control over paths searched but apart from testing latex base I don't think I have ever needed to adjust the paths, the files of the current repo will be in the current directory so found first and for everything else I just take the standard path
6:24 PM
@DavidCarlisle Ohh, hepnames...
6:50 PM
@mickep ?
@DavidCarlisle I don't want it finding .etx, .mtx etc. in TEXMFLOCAL. I can check manually, but I thought it would be more reliable to ensure failure if I've missed something. I have a lot of these kinds of files, most of which are of no interest to anybody else whatsoever. So I don't want to inflict them all on the world either.
@DavidCarlisle Oh, the question with S_{\pi^0\pi^0}...
(I thought you followed that one closely...)
[Or anything in TEXMFHOME, but I'm less worried about missing things there and it is easy to override that anyway.]
@mickep I'd moved on:-)
@DavidCarlisle Oh, lucky you.
6:54 PM
@cfr you can use os.setenv to set those to duck at the start of build.lua (I should think)
@mickep showing more high quality typesetting with luatex
@DavidCarlisle Where?
@DavidCarlisle Oh,very beautiful indeed. I feel the need for an upvote.
2 hours later…
9:26 PM
@DavidCarlisle I thought that would only work for TEXMFHOME, but it seems you're right. (Sorry.)
@cfr it happens sometimes.
10:01 PM
@DavidCarlisle And I should be ashamed.
Q: Strange work of showframe package

ASKrasnowI am trying to write a simple class and set all necessary parameters (paper size, font size, margins, header, footer, etc.) by myself. I do not want to load complex classes like article, report, book, etc. and then modify them reducing their functionality. I started from setting paper size in mm...

10:23 PM
@cfr and there was I trying to be @UlrikeFischer and read the documentation, and you be me and just use \show to get the answer directly:-)
@DavidCarlisle ? who did use \show? A the kp-fonts question
@UlrikeFischer kpfonts question (cfr)
10:40 PM
@DavidCarlisle ;)
10:53 PM
@DavidCarlisle Possibly because I'm frustrated by the Lua documentation. Who writes a manual that long without an index?
