Hyphenation in multi-language projects
by Steffen Wolfrum 24 Oct '22

24 Oct '22

Hi, please have a look at this minimal example. The idea is to set the hyphenation for certain words regardless of the language that is used in the surrounding paragraphs. In this example it should stay: «steff-en» How do i set this to all non-english paragraphs (without using \hyphenation on each language-switch)? Best, Steffen — \starttext \setuppapersize[A6][A6] \mainlanguage[en] \startexceptions steff-en \stopexceptions english text english text english teste: steffen \start\language[it] italian text italian text italian teste: steffen \stop \start\language[it]\hyphenation{steff-en} italian text italian text italian teste: steffen \stop \stoptext

TeXGyre Heros on Firefox
by juh 19 Oct '22

19 Oct '22

Dear all, there were some discussions on pdf viewers on the list and I know that things are not always fine. I now have a problems with the Firefox pdf viewer and TeX Gyre Heros. The font looks uneven in FF, no problems elsewhere. When I scroll into the pdf to set the display to 150% or more the font shows up just fine. So it seems to be a display problems with firefox. I tried several pdf versions no change. My configuration: \definefontfamily[mainfont][serif][texgyreheros] \definefontfamily[mainfont][sans] [textgyreheros] \definefontfamily[mainfont][mono] [texgyrecursor][features=none] \definefontfamily[mainfont][math] [texgyrepagellamath] \definefallbackfamily [mainfont] [rm] [Latin Modern Math] [scale=0.925, range=0x22C0] \definefontfeature[smallcaps][script=latn, protrusion=quality, expansion=quality, smcp=yes, onum=yes, pnum=yes] \setupalign[hz,hanging] \setupitaliccorrection[global, always] Is there anything I can do? And the is another issue: To my big surprise ArialBold MT is included into the file. I am using the current lmtx. If you want to see the effect, download the pdf. https://www.hostsharing.net/publikationen/vereinshandbuch/ Just click on "Anonym herunterladen" no need to register.

lmt_outline not rendering properly
by Jacob Kauffmann 14 Oct '22

14 Oct '22

Dear list, attached is an example taken from the luametafun manual. The letter o looks odd. When I compile the manual the examples in section 4 look also bad (different font; page 10 attached). It seems like the paths miss one point. This is with the latest version 2022.09.11 20:44. Cheers, Jacob

TOC colors and in-page anchors
by Sylvain Hubert 11 Oct '22

11 Oct '22

Dear list, \usemodule[ipsum] \setupinteraction[state=start] \starttext \completecontent \section{s1}\ipsum \section{s2}\ipsum \section{s3}\ipsum \section{s4}\ipsum \section{s5}\ipsum \section{s6}\ipsum \stoptext In the table of contents, s1 and s2 (at page 1) are rendered in red, while others in green. Moreover, when I click s4, it jumps to page 2 without locating the section precisely within the page. This is not the case when using the latex hyperref package. Does anyone know how to make the colors uniform and the links precise? Any help is appreciated. Sylvain

Missing letters and numbers in printout
by Angel M Alganza 29 Sep '22

29 Sep '22

Hello, I have a document that includes some grids (drawn with \grid) as well as alphanumeric information (letters and numbers) which contents (the info, not the grids) I modify every year and then print it out. I've been using it without any problem for a few (maybe 4 or 5) years but, this time, only the grid showed up on the printout, but none of the letters or numbers would, using the same printer I used every time before. I always copy the PDF file into a USB stick that I bring to the (departamental) printer, plug it in the printer and directly print from it. I tried printing the same file (from the same USB drive) into a different printer, this time connected to a computer, and sending the file from it, which worked just fine. My guess is that the first printer in missing the font the document uses, whereas the second printer received the font from the computer (Devuan Linux), which has the appropriate font. Could that be correct? In all previous ocasions I used the version of ConTeXt included in Texlive on Devuan, but a few months ago I decided to install ConTeXt using the official distribution instead. Could that explain the change in behaviour I'm seeing? Could it be that the previous versions I used somehow embeded the fonts into the PDF file but the current one doesn't? And, if that's really the case, how could I force the font to be included into the PDF file? I remember I read something like that a very long time ago (probably about LaTeX, not ConTeXt), but I haven't found how to do it now in a few searches on the documentation. Thak you for any help or advice. Cheers, Ángel

LMTX incompatibility in \meaning breaks TikZ, other minor issues
by Leah Neukirchen 28 Sep '22

28 Sep '22

Hi, I'm trying to get tikz-cd to run on LMTX and some examples already work fine, but I had a problem with text on arrows. To reproduce: \usemodule[tikz] \usetikzlibrary[cd] \starttext \starttikzcd A \arrow{r}{A} \NC B \NR \stoptikzcd \stoptext This builds fine on MkIV from TeXLive 2022 with LuaTeX, but on LMTX I get: system > ConTeXt ver: 2022.09.11 20:44 LMTX fmt: 2022.9.20 int: english/english ... close source > level 2, order 63, name 'tikzlibrarycd.code.tex' fonts > preloading latin modern fonts (second stage) fonts > 'fallback modern-designsize rm 12pt' is loaded tex error > tex error on line 8 in file ./tik.tex: Package pgfkeys Error: I do not know the key '/tikz/"{A}"{}' and I am going to ignore it. Perhaps you misspelled it.^^J...^^Jl.7 I think the culprit is a tikzcd arrow in cell 1-1 After a bunch of debugging, it turns out that LMTX breaks the TikZ 'quotes' library, which works using code ala: \def\tikz@enable@node@quotes{% \pgfkeyssetvalue{/handlers/first char syntax/the character "}{\tikz@quote@parser}% \let\tikz@quotes@as\tikz@node@quotes@as% } The last part of the /-key is derived from \meaning, but in LMTX, \meaning" is "the character U+0022 'quotation mark'" and thus the key cannot be found. I have patched TikZ for now to match for this alternate string too. But perhaps it would be better for compatibility to agree with the original TeX \meaning strings for the 7-bit ASCII subset at least. I found another minor nit that's not really triggering a bug but still a difference to LuaTeX: \eTeXrevision should expand to .2, but it expands to 2 in MkIX. There is some code out there which uses constructions like \number\eTeXversion\eTeXrevision or even \ifdim 0\XeTeXrevision pt > 0.9996pt As LMTX doesn't care about this macro, this should be easy to adjust. Thanks, -- Leah Neukirchen <leah(a)vuxu.org> https://leahneukirchen.org/

strange issue with hyphens
by Pablo Rodriguez 28 Sep '22

28 Sep '22

Dear list, I’m experiencing a weird issue with hyphenation: \setuphyphenation [method=traditional] \starttext \hyphenatedword{a-legibility-c} \sethyphenationfeatures [strict] \hyphenatedword{a-legibility-c} \stoptext I need the setup hyphenation commands to get underscore hyphenation. But how can I make that strict hyphenation features behave as standard hyphenation ones? I mean, that the first hyphen doesn’t get doubled and that hyphenation is also enabled after the first hyphen. I don’t know whether the strict hyphenation features are misbehaving here or I am missing something very basic here. Many thanks for your help, Pablo

Command for specifying et al limit
by Jethro Djan 28 Sep '22

28 Sep '22

Dear list, I am trying to specify that 'et al’ should be appended after the first author if paper has multiple authors. It seems from the mkiv-publications.pdf manual that it should work like this but it doesn’t. Here is my MWE: \startbuffer[ref] @Article{bb:2017, author = {Bronstein, Michael M. and Bruna, Joan and Cohen, Taco and Veličković, Petar}, journal = {arXiv preprint arXiv:2104.13478}, title = {Geometric Deep Learning: Grids, Groups, Graphs, Geodesics, and Gauges}, year = {2021}, } \stopbuffer \definebtxdataset[ref] \setupbtx[dataset=ref] \definebtxrendering [ref] [apa] [ dataset=ref, ] \usebtxdefinitions[apa] \usebtxdataset[ref][ref.buffer] \setupbtx[ dataset=ref, etaldisplay = 1, etallimit = 1, ] \starttext \cite[author][bb:2017] says in their paper \cite[bb:2017] \startsection[title={References}, number=no, incrementnumber=no] \placelistofpublications[ref][method=dataset] \stopsection \stoptext Thanks in advance.

lmtx status
by Hans Hagen 27 Sep '22

27 Sep '22

Hi, At the ctx meeting we released luametatex, that is, the source code is now in the context zip (so it grew a few MB). At the same time Mojca set up some contextgarden repositories on github. We're working on a setup for users to generate older snapshots, if needed (for instance because there are platform changes). She's also working on cmake based installation helpers. One of the things we did was pruning the fonts that are part of the installation. With a few exceptions the type one fonts were dropped, which is most noticeable for math. There is no need for px and tx fonts, they served their puspose in the transition from old style t1 fonts to opentype math (when we started with mkiv; we could have dropped them already). We're looking into antykwa math as well as in alternative script and calligraphic math alphabets so eventually virtual math from t1 construction can be dropped completely (in principle if can be integrated in the tweak mechanisms) because it is not wirth the effort to make them better. That means that we will ship some additional companion fonts. There are math times fonts but they are currently not free and there is some effort going on to turn them opentype so we can ditch their setups too (we can't test anyway; to some extend that is also true for minion math). High on the agenda is euler (in combination with pagella). This also relates to upgraded mixed script and calligraphic support in math. It actually means that enabling alternative alphabets will happen a bit differently (more naturally integrated as we introduced dedicated ranges of slots). Again a side effect is that we have more granular math glyph properties (opentype math is too limited but basically frozen so we have to get over that and move on). We (Mikael and me) also try to compensate for the ommissions and weird things in unicode math but it will take some time before we have that all documented. One of the next uploads will have the pruned / upgraded texmf tree (one can always install more in the local tree of course). At some point installing from the garden (or from a git clone) will also be supported (basically anyone can host a lmtx install). For the next texlive we hope to switch to lmtx as default and that also means that luametatex is the runner then. One can (as currently in lmtx) always run luatex with "--luatex". Als-in-all it's a lot of work but we're getting there.
