Re: [NTG-context] ntg-context Digest, Vol 205, Issue 1 // log: use \thinspace instead of \,
by Rudd, Kevin 21 Jul '21

Revisiting this one---as noted in the thread \, used to work in text mode; according to the logs it was deprecated and now produces an error preventing most of my documents from compiling. Is there solution that restores \, (and friends) for abbreviated spacing in text mode that doesn't require bulk changes to all of my documents (and making the source documents hard to type/read)? I appreciate using the more verbose \thinspace in macros but the abbreviations have real value in bulk text, especially when heavily used. I have many uses throughout my documents where I need a thin space (such as working with SI units) where it would be very awkward to use \thinspace everywhere in the source text. for example, consider a simple example that used to work but no longer does with the alternatives that I'm aware of: 32\,MiB--64\,MiB 32$\,$MiB--64$\,$MiB 32\thinspace MiB--64\thinspace MiB The difference in both writeability and readability for these cases is significant, especially when there are many uses close together in either text or table.

At least in German typography these “spatiums” are necessary. In French typography as well. Indeed, American: 10,000.00 French: 10\,000,00 (and other languages). This is quite readable, and much preferred to the use of any kind of macro that might format numbers according to language. I find that students often need such helpers when deciphering many digits. Let's not forget all of these spaces commands are used in math mode. Sure, and thet adaot to math mode. They will nto dissppear, it's just that in macros I like more verbose names. Hans Kevin W.

Mojca, sorry I missed you query about the location of the image zip. I used: https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2020-0… But the lite version you mention below should use the same library. > ....Does this look like the correct place for fetching the images with Debian 10? > https://downloads.raspberrypi.org/raspios_lite_arm64/images/raspios_lite_ar… > > Mojca Regards, Jay p.s. I'm away from the rpi now but will try out the new runtime prog you sent and get back to you. --- END

languages
by Hans van der Meer 18 Jul '21

18 Jul '21

Here is something I think that should be added to the documentation. In the ConTeXt garden (page Command/mainlanguage) the description is: mainlanguage Set the language of auto-generated language elements, like the title of the table of contents or the appendix. On the Command/language page: Change the hyphenation rules, quotation marks, all that sort of thing, to that of a different language. (The default language is English.) Testing showed that \mainlanguage sets both \currentlanguage and \currentmainlanguage to the same value, while \language sets \currentlanguage only. My suggestion is to add info to this behaviour to the mainlanguage page, reflecting the fact that \mainlanguage does set both \currentlanguage and \currentmainlanguage.Which is not apparent from the current documentation. Another solution would be to separate \language and \mainlanguage completely. An option I would prefer for clarity, because now the order of calling \language and \mainlanguage makes a difference. dr. Hans van der Meer

date formatting
by Hans van der Meer 18 Jul '21

18 Jul '21

From Wikipedia: In English-language <safari-reader://en.wikipedia.org/wiki/English_language> outside North America (mostly in Anglophone Europe and some countries in Australasia), full dates are written as 7 December 1941 (or 7th December 1941) and spoken as "the seventh of December, nineteen forty-one" (exceedingly common usage of "the" and "of"), with the occasional [my emphasis] usage of December 7, 1941 ("December the seventh, nineteen forty-one"). In common with most continental European usage, however, all-numeric dates are invariably ordered dd/mm/yyyy. From this I infer that \language[en] or \language[en-gb] should format dates normally in day-month-year order, reserving mont-day-year for \language[us] i.e. language[en-us]. But in ConTeXt both \language[en] and \language[en-gb] produce the us ordering for \currentdate. I would be pleased if ConTeXt could be changed to the above mentioned normal behaviour for english. That is [en] and [en-gb] produce the day-month-year order and that [us] and [en-us] month-day-year. dr. Hans van der Meer

Moving the old book-structure to a recent ConTeXt
by Gerben Wierda 18 Jul '21

18 Jul '21

Years ago I wrote a book (Chess and the Art of Enterprise Architecture) using ConTeXt. The setup was (I think Taco’s) basic book project setup, with a chapters, environments, products, etc. subdirectory where you work in the chapters directory and can both produce individual chapters and the whole book. The main tool to produce was texexec. ConTeXt has moved on considerably since then (2014-2015). So, I tried teh old project to see if it still works, but found out it didn’t. There still is a texexec in my MacTeX, but the compilation fails: texexec --pdf --mode=SCREEN ../products/prd_book.tex resolvers | initialization | fatal error: kpse library is accessed (key: original) Is there a new ‘book’ project structure/template for the modern/standalone ConTeXt? Note, I have both a standalone ConTeXt (for another project) and the MacTeX distribution on my system.

Based on Debian/Linux 10 Lutz, jdh, thanks for testing, great to hear that it works! Although now it remains to apply this technique to LuaMetaTeX. Without access to source code I can't try anything, but the general ideas should apply: I used Zig for cross compiling. While Zig is a full fledged programming language in its own right, it also has the ability to compile C/C++ (with built-in Clang). The more interesting part is that it also bundles different C libraries for the different targets it supports for cross compilation. This is a great match for Lua(Meta)TeX, because standard C library is the only "external" dependency. Depending on the chosen target (CPU+OS+ABI triple), the binary can then be fully statically linked or dynamically linked against the target's system C library. Zig exposes the "C compiler" functionality with two interfaces: the Zig build system and the "zig cc" command. In theory "zig cc" should be a drop-in replacement for "clang" or "gcc" [1] and therefore should be usable with existing build systems used by LuaTeX/LuaMetaTeX. In practice it is not that easy, because some "compiler feature detections" of these build systems often try to run compiled results (and fail). But in the best case (like with Lua) cross compilation may be as easy as: # "bsd" is almost like "linux", but doesn't link "readline" make CC="zig cc -target aarch64-linux-musl" bsd The result is a fully statically linked executable, that can be used on all Linux distributions. But because it is statically linked, dynamic loading of external Lua libraries written in C is not possible. The following will result in a binary that is dynamically linked against (the target system) glibc and should be able to load even Lua libraries written in C: make CC="zig cc -target aarch64-linux-gnu.2.28" bsd (Note that Zig support all relevant glibc versions, that means that compiling for older Linux distributions can be done from any OS, not just ancient Debian or CentOS. Here "2.28" is old enough to support jdh's Raspberry Pi OS -- and anything newer.) Applying this to LuaMetaTeX may or may not be hard. Frankly I don't know much about CMake. But I have experience converting LuaTeX (or rather its subset) to another build systems: 1) https://github.com/vlasakm/mmtex/blob/ltex/build.zig This was used to produce the two binaries I sent previously. Usage (no setup required): wget 'https://github.com/vlasakm/mmtex/archive/refs/tags/cross-test2.zip' unzip cross-test2.zip cd mmtex-cross-test2/ wget 'https://ziglang.org/download/0.8.0/zig-linux-x86_64-0.8.0.tar.xz' tar xf zig-linux-x86_64-0.8.0.tar.xz zig-linux-x86_64-0.8.0/zig build -Dtarget=aarch64-linux-musl qemu-aarch64 zig-out/bin/mmtex --help Something similar should work on Windows/Mac and for other targets (see `zig targets`). 2) https://github.com/vlasakm/mmtex/blob/master/mmtex/files/meson.build This one compiles full LuaTeX, although it doesn't support cross compilation and links to system zlib, libpng and zzliplib. The Zig cross compilation is sadly limited (https://ziglang.org/download/0.8.0/release-notes.html#Tier-1-Support) but not because more exotic systems will never be supported, it's just that nobody did the required work, yet. The support for Linux (various architectures), macOS (aarch64+x86_64) + Windows (x86_64) should be very good. I don't think there is other cross compiler that is able to target the M1 Macs. The Zig build you download from their website [2] is kind of huge, but note that it includes LLVM+Clang+Zig in one single dependency free binary + (efficiently packed) C libraries for many targets. I.e. this is all you need for all your C/C++/Zig. Provided that you (as of now) don't need anything other than Linux/Mac/Windows. Hans, Mojca, is this something worth pursuing for LuaMetaTeX before "native" compilation is available? I am interested in trying.
