Losing a character during line break at a hyphen
by Bruce Horrocks 22 Aug '21

22 Aug '21

Not sure whether this is a ligature problem or a hyphenation problem or both! In the following MWE, the line breaks at the hyphen following "Diffe", but one of the f's is lost so the PDF shows "Dife-". Latest LMTX, version 2021.08.19 19:48 \starttext Twenty years after receiving it as a Christmas present, I have finally got around to reading The Code Book by Simon Singh. Written in 1999, when E-commerce was still relatively new, the book provides accessible explanations of the workings of Diffe-Hellman-Merkle key exchange, and Rivest, Shamir and Adleman (RSA) public-key cryptography. \stoptext Output PDF attached. — Bruce Horrocks Hampshire, UK

If you look at the screen shot you can see that the older emails all display the sender's name in the list. Under the new system (just the topmost entry, shown selected) every email comes from "ntg-context(a)ntg.nl" which is completely useless when you want to visually scan down the list for a particular person. It doesn’t make sense to argue about this, but it’s apparently a setting (or unchangeable behavior) of your Email app. My Apple Mail 12.4 on Mojave shows the same message like attached (dark mode).

different preffixsegments for different reference formats
by Pablo Rodriguez 21 Aug '21

21 Aug '21

Dear list, I have the following sample: \starttext \definereferenceformat[itsc][in] \setupreferencestructureprefix[itsc][default] [prefixsegments=section] \chapter{Chapter} \section[b]{Section} \itsc[b] and \in[b] \stoptext How can I get that \itsc gets "prefixsegments=section" without affecting to \in? Many thanks for your help, Pablo -- http://www.ousia.tk

ConTeXt support for Panic's Nova editor
by Felix Krause 20 Aug '21

20 Aug '21

Hi folks, I made a TeX extension for Panic's Nova editor (https://nova.app) with explicit ConTeXt support, available here: https://extensions.panic.com/extensions/org.flyx/org.flyx.tex/ It features syntax highlighting, suggestions for builtin commands, code folding, auto-completion of stop commands, and structural overview of headings in the symbols sidebar. It also enables the editor's spell checking for non-command text. I don't recommend buying this editor specifically for your TeX needs, but since I own it anyway I thought it would be nice for it to have TeX support. Cheers, Felix

lmtx update
by Hans Hagen 20 Aug '21

20 Aug '21

Hi, Here are the highlights of todays update: - somewhat more compact tuc files, not for all documents, but it can accumulate; also less memory used then; i could bring down an extreme 2000 page 5 column doc tuc file down to 5% -- it was 70 MB; for the luametatex manual it reducec the tuc more than 30%; hard to tell if there will be an associated performance hit, but i'm sure thomas will complain if that's the case - more mp-tex-lua interfacing upgraded plus extra preliminary chapter for luametafun about extensions - for taco - a slightly more compact cache files for fonts with many (pseudo) ligatures; hopefully no side effects (nothing that can't be fixed fast if noted); quite probably no performance hit and maybe even some room for optimization (not done yet) - a split in the cache directory for luametatex so that we can more easilly experiment without interference (so, although the above works in mkiv it's not enabled there currently) - some minor things (also in the process of splitting the codebase) - no real changes in / additions to the luametatex binary (we're in cosmetics mode now) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

paper dimensions for TEXpage

Dear list, I have the following sample: \definelayer[hi][x=.5\paperwidth, y=.5\paperheight] \setupbackgrounds[page][background=hi] \starttext \setlayer[hi]{hi} \startTEXpage[offset=10em] \null \stopTEXpage \stoptext I don’t get the layer in the TEXpage. How could I get it with the TEXpage dimensions? Many thanks for your help, Pablo -- http://www.ousia.tk

Different footers for frontmatter and bodymatter
by noib3 18 Aug '21

18 Aug '21

I'd like to have two different footer setups: one for the frontmatter (titlepage and table of contents) where the page number in roman numerals is reported as a single centered footer. Another for the bodymatter where the chapter is on the left footer and the pagenumber is on the right. I can switch between roman numerals and numbers with ``` \defineconversionset [frontpart:pagenumber] [] [romannumerals] \defineconversionset [bodypart:pagenumber] [] [numbers] ``` but I can't figure out how to have two different footer setups. Right now I have ``` \setupfootertexts [chapter] [pagenumber] ```

Unicode normalization and Hebrew in ConTeXt
by Joey McCollum 18 Aug '21

18 Aug '21

I am typesetting a document in Hebrew that includes pointing (e.g., vowels, shin and sin dots, dagesh, etc.) using ConTeXt. The Hebrew text that I want to typeset has been normalized into Unicode's NFC canonical form. It is well-known that the Unicode canonical ordering of Hebrew points conflicts with the recommended mark ordering of specific points based on their functions (see https://www.sbl-site.org/Fonts/SBLHebrewUserManual1.5x.pdf for more on this topic). Thankfully, many typesetting engines automatically reorder the points to ensure that they are combined according to the specifications of many fonts. I'm pretty sure that XeLaTeX is one of these, as it typesets Hebrew letters with multiple points correctly even when the Hebrew text is in NFC form. My question is, can ConTeXt with LuaTeX handle the same situation correctly? In the following minimal example, ConTeXt typesets pointed Hebrew correctly when the characters are in the typographically recommended order, but not when they are in Unicode canonical order: ``` %Setup Hebrew text font: \definefontfeature[f:pointedhebrew][default][ ccmp=yes, mark=yes, script=hebr ] \definefontfamily[hebrew] [rm] [SBL Hebrew] [features=f:pointedhebrew] %Set the body font: \setupbodyfont[hebrew] %Set up right-to-left alignment: \setupalign[r2l] \starttext %Characters after normalization, in Unicode canonical order (bet + segol + dagesh + final nun): בֶּן %A word with characters in typographically recommended order (bet + dagesh + segol + final nun): בֶּן \stoptext ``` I typeset this using ConTeXt version 2020.03.10, as released with TeXLive 2020. I got the SBL Hebrew font from https://www.sbl-site.org/educational/BiblicalFonts_SBLHebrew.aspx. According to the font's user manual (see the link above the MWE), the font should be able to combine the marks to form the correct glyph regardless of their order after the consonant, but that doesn't seem to be the case here. I also tried using the predefined "hebrew" featureset, but that did not change anything. Is there some other OpenType feature or featureset I need to enable to fix this, or is there some module or option I can include to get ConTeXt to typeset Unicode-normalized Hebrew as if it were ordered in the recommended way, like XeLaTeX does? I see that the uninormalize module is mentioned in the thread "XeLaTeX, LuaLaTeX, fontspec, unicode and normalization" on TeX Stack Exchange ( https://tex.stackexchange.com/questions/229044/xelatex-lualatex-fontspec-un…) can that be used with ConTeXt? Thank you, Joey

file to buffer
by Hans van der Meer 17 Aug '21

17 Aug '21

Is it possible to retrieve the contents of a file directly into a buffer? On the Wiki I could not find such a command. That is, equivalent to something like: \startbuffer[from file] contents of the file \stopbuffer dr. Hans van der Meer

Where is this message on luacondition 733 coming from? I would be glad to get rid of it. The message does not pinpoint the problem location enough for me to find its cause. close source > level 2, order 7, name './modules-docs.tex' close source > level 1, order 7, name 'cont-yes.mkiv' (\end occurred when luacondition 733 on line 8 was incomplete) dr.
