Hi, I use the lua function img.scan{filename}, but in lmtx I get "attempt to index a nil value (global 'img')", so I guess this got renamed or moved? HR

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

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

Hyphenation again
by Denis Maier 06 Jun '21

06 Jun '21

Hi, another weird thing: In this example I use \startexceptions to set hyphenation exceptions: ``` \mainlanguage[en] \startexceptions[en] appli-cable obli-gated \stopexceptions \setuplayout[width=1cm] \starttext \currentmainlanguage \currentlanguage \hyphenatedword{applicable} applicable \hyphenatedword{obligated} obligated \stoptext ``` What am I missing? Best, Denis

Hyphenation patterns
by Denis Maier 09 Apr '21

09 Apr '21

Hi, where can I find the hyphenation patterns used by ConTeXt? I have two wrongly hyphenated words, and I want to check whether this is due to incorrect patterns. (I tried the source browser... not much luck so far.) The words are: 1. applicable => hyphenated as applic-able 2. obligated => hyphenated as oblig-ated I know I can use \hyphenation to correct that, but I wanted to check the patterns nevertheless. Best, Denis

Markdown module in LMTX
by Christoph Reller 28 Mar '21

28 Mar '21

Hi, In recent versions of ConTeXt LMTX, the builtin markdown module is missing. (Files m-markdown.[lua|mkiv]) Just copying this module from an earlier version shows that they don't work anymore. MWE: ConTeXt file: -- 8< ------------------------------------------ \usemodule[markdown] \starttext \processmarkdownfile{file.md} \stoptext -- 8< ------------------------------------------ file.md: -- 8< ------------------------------------------ Title ===== Here comes a paragraph text. -- 8< ------------------------------------------ Are there plans to add and update this module? Cheers, Christoph

printing the current date
by Peter Münster 13 Mar '21

13 Mar '21

Hi, I would expect, that \currentdate prints the current date, but it does not: --8<---------------cut here---------------start------------->8--- \starttext \date[d=1]% first day of this month, ok \date% again first day, last parameters are used, this is ok \currentdate% same as \date, but I would expect the day of today... \stoptext --8<---------------cut here---------------end--------------->8--- How could I print the current date please? TIA for any hints, -- Peter

externalizing TikZ graphics
by Henning Hraban Ramm 06 Mar '21

06 Mar '21

Hi, did anyone succeed in externalizing TikZ graphics with ConTeXt? It’s about a project with hundreds of diagrams that (in the current state) clutter the main directory with cryptically-named PDFs (at least sorted by component name) and that on each ConTeXt run take a lot of runtime (I guess also the many log lines slow the process). In 2013, Aditya said it wasn’t possible to externalize pgf/TikZ graphics as documented in the pgf manual, and "perhaps" it would make sense to use his filter module: https://mailman.ntg.nl/pipermail/ntg-context/2013/071162.html Did anyone try to do that? I didn’t find anything in this list’s archives. The original pgf way is two-pass, and you’d need to call LaTeX with the intended graphics name as --jobname; that’s far too much of a hassle for that many graphics. I generally like how the filter module works, as you can also define the name of every buffer, but my only experience with that is my LilyPond setup. If nobody has better advice, I’ll try to come up with a filter setup. That would mean we’d avoid the tikz module, every TikZ diagram will get written to a buffer of configurable name, and that (with preamble setup) will get run through LaTeX. I read pgf had some restrictions in plain TeX mode, but perhaps we can also use LuaTeX in plain mode to avoid the LaTeX dependency. Best, Hraban

lmtx-20210118 | Corruption with rotated floats
by Richard Mahoney 01 Feb '21

01 Feb '21

List members, I've found that recent versions of LMTX seem to have broken table and figure floats using rotation. Lmtx-20210118 with for example: \placetable[here,90] results in the trashing of all subsequent body text in the PDF. This can be corrected with something such as: \placetable[here] ... \framed[orientation=90] (although one looses the ability to rotate the title of the table). The last really stable version of LMTX, which I'm finding that I'm constantly returning to as my default, is lmtx-20200920. This error has been occurring for some time now, and unfortunately, while I would like to keep up the recent releases of LMTX, it is essential that I should be able to rotate tables and images. Does anyone know of a fix.

font fallback hook (alphabet suspects)
by Jano Kula 01 Feb '21

01 Feb '21

Hello to everybody! Warning: 50 % of Greek glyphs in MWE, so they might be randomized :) Is there any hook in the font fallback? There are some Greek, Hebrew, etc. words used in the text. While proofreading, the editor would like to check these words separately (glyphs from different alphabets, unusual symbols, ...), so I'd like to typeset the warning (margin note), where these words are located. To avoid usual markup \greek{ὀρφανῖος} it could be useful to typeset a margin note whenever the defined fallback is called. The unfamiliar symbols could be in the main font and no fallback would be called then (one can still define the fallback with the main font as in the MWE, bold used for the illustration), but you might have a better ideas how to point out these suspects. The margin note is ment for searching PDF where one cannot search for color (basic viewer), which could be the other approach (also visible in print). I think, the color could be achieved with finalizers. One should also think of hyphenation and l2r/r2l direction, so in the end the usual approach might be the best way. You might use other approaches, how to deal with suspects of this type. Below the MWE for font fallbacks with distribution fonts. Not critical, just looking for ideas. Thank you, Jano \definefontfallback[Fallback] [file:DejaVuSerif-Bold.ttf] [0x0370-0x03FF] [force=yes,rscale=1] \definefontfallback[Fallback] [file:DejaVuSerif-Bold.ttf] [0x01F40,0x01FD6] [force=yes,rscale=1] \starttypescriptcollection[DejaVu] \starttypescript[serif] [DejaVu] [name] \definefontsynonym[Serif] [file:DejaVuSerif.ttf] [fallbacks=Fallback] \stoptypescript \starttypescript[DejaVu] \definetypeface[DejaVu][rm][serif] [DejaVu][default] \stoptypescript \stoptypescriptcollection \setupbodyfont[DejaVu] \starttext from ὀρφανῖος, thus \stoptext
