@DavidCarlisle thanks, added that to the issue.
 
@KhaledHosny yes thanks I'll track this there. I'm rebuilding on cygwin again (as I built the linux version over the previous attempt) so I expect it will stop in same place, but I'm going to give up for tonight :-)
 
12:41 AM
@KhaledHosny cygwin: This is LuaTeX, Version 1.09.0 (TeX Live 2019/dev) good night:-) (I left the diff in that gh issue)
 
 
1 hour later…
1:56 AM
@UlrikeFischer You don’t need luahbtex to test this, I can reproduce the same issue with luajittex and the ffi examples (you will need harfbuzz dll and editing the tex file to point to that dll).
 
 
6 hours later…
7:28 AM
Bulk update of my biblatex styles last night ...
 
@JosephWright \msg_error:nnn {uftag} {mc-nested}{1} now outputs
! Package tagpdf Error: nested marked content found - mcid 1
;-).
 
@UlrikeFischer Sounds good to me
@UlrikeFischer As requested :)
 
@JosephWright ;-) . And I had to add only one line ...
 
@UlrikeFischer Which was?
@UlrikeFischer Ah, the name mapping, of course
 
@JosephWright yes. Btw: As I wanted to try the name mapping and texlive hadn't it already I ran l3build install --texmfhome=./texmf yesterday in the latex3 git (in a local testing branch ..) and got lots of texmf-trees in all subfolders. I had to use an absolute path to get it working.

@JosephWright ^^
 
@UlrikeFischer I see the issue: I'll fix shortly
@DavidCarlisle WOW!
 
@JosephWright I don't actually know how to use it, but it compiles (in cygwin and windows linux subsystem) I guess I need @WillRobertson to give me a fontspec interface....
 
8:54 AM
@DavidCarlisle at least you don't have a windows version so you can't lead me into temptation ...
 
@UlrikeFischer I tried cross compiling for mingw64 but it said that I had incompatible commandline arguments and I couldn't figure out what it wanted. It might anyway be simpler to accidentally mention this to Akira and see if a windows build apears...
@UlrikeFischer I think the windows linux subsystem is as near to "native windows" as I want to get:-)
 
@DavidCarlisle asking Akira is the plan ;-). But only if we know that it works in prinzip. Btw: I plan a luaotfload upload shortly, and with it you can suppress luaotfload with the --safer option. Could be useful for tests.
 
9:15 AM
Quack!
 
@PauloCereda you killed my java program
 
@DavidCarlisle oh no
 
@PauloCereda on a scale of 1 to 10 how good is to get java.lang.StackOverflowErrorjava.lang.StackOverflowError followed by 1026 lines of stack trace?
 
@DavidCarlisle hmm.... 2? :)

Hi everyone, I have a question regarding numbering of theorem etc. environments which I couldn't find on the site but suspect has been asked before. I would like to do the following: Have a document where the counters of these environment indicate subsection (e.g. Theorem 1.1.5; I know how to do this), except for one section, where I want them to only indicate the section (e.g. Theorem 1.5). How can I make this change (inside a single document)?
Summary: I want to change the type of numbering for math environments (theorems, etc.) in a certain part of my document. How can I do this?
 
@Danu \renewcommand\thetheorem{\thesection.\arabic{theorem}}\removefromreset{theorem{‌​subsection} at the start of the section (and put it back again at the end)
 
@DavidCarlisle Thank you for your quick response. Unfortunately, that doesn't compile for me (\thetheorem undefined). I'm using the package amsthm if that's any help
 
@Danu well you didn't say what counter your throrems were using, amsthm doesn't define any just gives you a way to define them, replace theorem by whatever you have
 
10:24 AM
Ah, that works like a charm. Thank you very much!!

@Skillmon Let us blame David Carlisle
 
@DavidCarlisle We still need a bit of Lua glue code to actually integrate HarfBuzz and then can provide a luaotfload-like interface.
@UlrikeFischer Using the new files from context makes things to work, I have something to work with now, so ignoring luaotfload issue for the moment.
 
@KhaledHosny it should be possible to load fonts also with luaotfload, so we will probably have to integrate an alternative loader. But not this week ;-).
 
@KhaledHosny yes sure, I never got the previous attempts to work in my setup eg github.com/deepakjois/luatex-harfbuzz so I never really looked at the details of how that would work, but I'm sure @UlrikeFischer @MarcelKrüger and @WillRobertson (also @michal.h21) would be interested in getting a natural interface to this...
 
12:48 PM
Should I blame @JosephWright or @WillRobertson for this changes in the log?
old: .  This font family consists of the following NFSS series/shapes:
new: (fontspec)              This font family consists of the following NFSS
 
@UlrikeFischer Joseph, definitely Joseph. I can't think who could have suggested such a thing.
 
@DavidCarlisle Hm. Does that means that there is a third suspect to consider?
 
@UlrikeFischer git logs will show Joseph is to blame. So unless you want to invoke collective team responsibility (in which case we could blame you....)
@UlrikeFischer more seriously the 2e style where the package/module name is repeated on each line has some advantages when trying to filter the log files for specific types of message.
 
@DavidCarlisle Yes, I remember the discussion. It took me a bit by surprise that the tests suddenly failed today - I hadn't really realized it would affect information messages too.

Nutella pizza is good.
 
@PauloCereda How about a /pizza command that shows how real pizza should look like?
(Just don't let David pick the images :)
 
/wiki pizza
 
Pizza is a savoury dish of Italian origin, consisting of a usually round, flattened base of leavened wheat-based dough topped with tomatoes, cheese, and various other ingredients (anchovies, olives, meat, etc.) baked at a high temperature, traditionally in a wood-fired oven. In formal settings, like a restaurant, pizza is eaten with knife and fork, but in casual settings it is cut into wedges to be eaten while held in the hand. Small pizzas are sometimes called pizzettas. The term pizza was first recorded in the 10th century in a Latin manuscript from the Southern Italian town of Gaeta in...

Better!
 
but mine is the genuine American original, frozen in a cardboard box, not some Italian copy.
 
/say
 
To an outside spectator he would find on the doorstep of our English literary salons
 
@DavidCarlisle How can it be original with "NEW" in big letters on it?
 
5:04 PM
@DavidCarlisle I happen to live in California. I think that this "California kitchen" does not refer to the real California. Any chance it is based somewhere in the UK?
 
California is small suburban area of Birmingham, England. It lies within Bartley Ward and the Birmingham Edgbaston constituency and is located on the edge of Woodgate Valley Country Park. == History == Originally located in the parish of Northfield and part of Worcestershire the settlement of California takes its name from the California Inn built by Isaac Flavell on the junction of Barnes Hill and Alwold Road. Flavell bought Stonehouse Farm and the surrounding land in 1842, and set up a brick building business. There are tales that the name of the California Inn was taken from the state ...
@marmot Seems to be the most logical explanation
 
@samcarter Yes, this must be it. The by far worst "food" I ever had was in Liverpool, which is not too far from Birmingham. Most likely the Liverpool "cook" and "California kitchen" are related. ;-)
 
@marmot Did you retrieve your crystal ball? I could make good use of it today - somehow nobody seems to be in the mood to actually make a MWE when asked for one :(
 
@samcarter No, unfortunately not. And yes, on some special days (which happen about 365 times in a given year) users are somewhat reluctant to provide an MWE...
 
@marmot I had very good food in the UK, for example one conference dinner was in an Indian restaurant.
 
5:17 PM
/say
 
At last, after four years, and I can go ahead
 
@marmot You mean there is one day every \approx 4 years which has MWEs? I'll have to mark this in the calendar to have something to look forward for!
 
@samcarter Yes, the Indian restaurants there allow one to survive. (But I was dragged to an "Italian" restaurant in Liverpool and their "spaghetti" turned out to be overcooked pasta with ketchup.... ;-)
 
@marmot sounds - how to say? - British :)
 
@samcarter I generally like their humor (Monty Python etc.) but some of them do not seem to know where to stop... ;-)

@DavidCarlisle It probably isn’t that different, this example was probably chosen to show that ConTeXt font loader is not that bad. The differences are in 1) completely unsupported scripts by context or 2) subtle OpenType magic. At some point I’ll start collecting examples for @UlrikeFischer, but I’m not doing that now.
