composing commands
by Hans Hagen 11 Oct '21

11 Oct '21

Hi, As I'm going over the commands in lmtx, I wonder if we should keep \c \d \k \r \u \v \" \' \` \^ etc ... the ones that make 'composed characters'. I think that anyone who needs them uses utf . They can be in (say) m-oldschool.mkxl or so. Objections? Hurt feelings? Sentiments?

one quick remark about textext.dflt (vs textext.dlft)
by Garulfo 05 Sep '21

05 Sep '21

Hi all, one remark, I was expecting to be allowed to use textext.dlft but finally the appropriate command appears to be textext.dflt which require to switch F and L letters. Is it on purpose ? would it make sense to have a dlft version to match LeFT ?

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

Footnotes in columns
by Clyde Johnston 13 Aug '21

13 Aug '21

I can no longer print the footnotes when I using columns in LTMX. If I remove the \{start|stop}columns, it works fine. This works on my old MKIV 2018.07.02 14:39 version. \setupcolumns[n=2,rule=off,balance=no] \starttext \startcolumns \input ward\footnote{A small footnote here} \stopcolumns \stoptext Context Version: 2021.01.24 16:07 Clyde

A not so short introduction to ConTeXt Mark IV
by Joaquín Ataz López 28 Jul '21

28 Jul '21

Hello to all: Two months ago I informed to the list that I had written an introduction in Spanish to ConTeXt Mark IV. This interested several people, and in order to increase their potential audience, a member of this list (native English speaker) has proceeded to translate my text into English. It is precisely the members of this list who need no introduction at all, but it can sometimes be useful to help someone get started with the fascinating typesetting system that is ConTeXt. As for the English translation, I have made some small changes to the Spanish version, so anyone who understands Spanish and prefers to read it in its original language can download the new version: Both versions are available at the following links - Spanish: https://webs.um.es/jal/docs/introCTX_esp.pdf - Engilish: https://webs.um.es/jal/docs/introCTX_eng.pdf Soon I will send both texts, with their source files, to the documentation section of the CTAN repository. -- Joaquín Ataz López Derecho Civil Universidad de Murcia

Call for papers: CG journal 2020
by Henning Hraban Ramm 24 Jul '21

24 Jul '21

Hi, do you remember our ConTeXt meeting 2020 in Sibřina? (programme attached) There were some interesting talks and presentations that should get preserved in our current journal (to be distributed at the meeting in Bassenge this fall). Also, additional articles are always welcome – there were a lot of interesting new features and solutions since then. So far, I/we got only one(!) article, by Taco on MetaPost. Please don’t let me/us down and hand in your articles until end of July (but ASAP)! @Harald: Please send the latest version of your German report, too! I’ll translate it into ConTeXt. Thank you – I’m looking forward to another interesting issue of CG journal! Yours, Hraban

Proper ligatures in Malayalam
by Ajith R 14 Jul '21

14 Jul '21

Hi, I tried to make a document in Malayalam, an Indian language. However, the ligatures don't form as expected. A minimal example is \mainlanguage[ml] \definefontfamily [malayalam] [ss] [Rachana] [features=malayalam-one] \definefontfeature[default] [mode=node,kern=yes, liga=yes,tlig=yes, ccmp=yes,language=dflt, protrusion=quality, expansion=quality] \setupbodyfont [malayalam] \starttext അദ്ധ്യായം \stoptext What setting am I missing? The expected form is show in libre office with the same text and font, attached as an image The sequence of Malayalam characters used is U+0D05 U+0D26 U+0D4D U+0D27 U+0D4DU+0D2F U+0D3E U+0D2F U+0D02 Thanks, ajith

A not so short introduction to ConTeXt - French version - progress report.
by Garulfo 13 Jul '21

13 Jul '21

Hi all, Joaquín I hope your are doing well. To keep you informed of my progress on the French version of "a not so short introduction to ConTeXt", I am done for part I, and II, and I am starting with Part III... I really appreciate Joaquín's Introduction, its structure, the sequence of steps. Thanks again for that. The latest french pdf can be found here : https://raw.githubusercontent.com/contextgarden/not-so-short-introduction-t… The GitHub directory is here : https://github.com/contextgarden/not-so-short-introduction-to-context/tree/… I added some content : - 6.7 : how to use fonts from the operating system - 7.4.3.D : tweaks with sectionconversionset - p.6 : kind of "visual Table of Content" - 9.6 : attachements I added some "features" : - use of ~10 environnement files for typesetting configuration - colors : to provide a somewhat attractive document inspired by Hans Hagen "Typographic Programming" https://www.pragma-ade.com/general/manuals/style.pdf - commands to typeset Demos (showing code and results side by side) - some attachments to provide "ready to go .tex for beginners" Some thoughs: - to move "page break section" from Part I section 5.5 to something like Part III 11.x - Once the translation finished, to simplify some explanations.

LMTX: different output if dots are used in the file name
by Marco Patzer 09 Jul '21

09 Jul '21

Hi! LMTX and MkIV behave differently if dots are used in the file name. Example: printf '%s\n' '\starttext\null\stoptext' > foo.10.tex && context foo.10.tex MkIV: → foo.10.pdf LMTX: → foo.pdf Is this intentional? This is LuaMetaTeX, Version 2.06.05 current version: 2020.05.25 23:39 Marco
