add more blank space when using \starteffect[hidden]
by Jeong Dal 17 Mar '21

17 Mar '21

Hi, Sometimes, I need to hide the solution of a problem. So I use \doifmode{} and \starteffect[hidden] as in the following sample file. Since I want to set more blank space if it is hidden, I add \blank[5cm] when it is in the \enablemode[hideSolution]. It works well except the figures and bars are not hidden. Only texts, even in the mp part, are hidden. It is OK for me. However, it would be much better to set the height of blank space depends on the height of hidden texts. Is there a way to set the variable height using “overlay” stuff instead of \blank[5cm]? Thank for reading. Best regards, Dalyoung \startbuffer[circles] draw fullcircle scaled 1cm; draw fullcircle scaled 1cm shifted (2cm,0); dotlabel.top(“O”,origin); \stopbuffer \def\StartHide{\doifmode{hideSolution}{\starteffect[hidden]}} \def\StopHide{\doifmode{hideSolution}{\stopeffect\blank[5cm]}} %\enablemode[hideSolution] \starttext \framed[]{This is what I want:} \framedtext[]{ \StartHide \samplefile{knuth} Overbar is not \overbar{hidden}. {\processMPbuffer[circles]} \StopHide } \stoptext

Chemical reaction formulas
by David van Diepen 17 Mar '21

17 Mar '21

Dear list, According to the information on contextgarden (section chemistry) chemical reactions should be entered as follows: \usemodule[chemic] \startformula \chemical{CaCO_3(s),+,HCl(g),->,CaCl(HCO_3)(s)} \stopformula That produces a formula with the comma's in it, so that's not good. If I enter it as follows \usemodule[chemic] \startformula \chemical{CaCO_3(s) + HCl(g) \rightarrow CaCl(HCO_3)(s)} \stopformula Then somehow after the \rightarrow the math/chemical environment is lost and the remainder gets typeset as text. The same is true if I use any math command such as \beta or \cdot. The closest I get to the desired result is with the following: \usemodule[chemic] \startformula \chemical{CaCO_3(s) + HCl(g) --> CaCl(HCO_3)(s)} \stopformula But that is a bit of a compromise. Regards, David van Diepen

getnonfreefonts with LMTX
by Philipp A. 14 Mar '21

14 Mar '21

Hi! The LMTX distribution comes with few binaries, texlua being none of them. The getnonfreefonts <https://www.tug.org/fonts/getnonfreefonts/> script seems simple enough, but it relies on a global “kpse” which it uses to get kpse variables. Therefore luametatex --luaonly can’t execute it. Is there a way to get those fonts with the standalone LMTX distribution? Best, Phil

tlig feature sometimes does not work
by Mohammad Hossein Bateni 14 Mar '21

14 Mar '21

Hi, Since most fonts do not have the standard tex ligatures built in, I tend to add them when I load the fonts. Once in a while, I run into fonts where this does not work. See the attached tex/pdf files. I basically load the font as follows: \definefontfeature[tf][arabic][tlig=yes] \definedfont[dejavusansmono*tf] This works fine for DejaVuSansMono and for one Farsi font I use ( https://github.com/rastikerdar/vazir-font/blob/master/dist/Vazir-Regular.ttf) but not for this other Farsi font ( https://github.com/aminabedi68/Mikhak/blob/master/Font/ttf/Mikhak-Medium.ttf) Perhaps this is because the last font is not standard, but TrueType/OpenType standard is sometimes up for interpretation. I see two strange symptoms here: \showotfcomposition displays the tlig feature differently for the last font. It appears in the "extra" list, not in "basic". Why is that? What does this mean anyway? In the pdf, you see two unicode characters U+647 and U+654 following the numbers and dashes. This usually has a ligature turning the two characters into U+6C0. It happens for VazirRegular but not for Mikhak-Medium. Why is that? I have looked in the font: the ligature exists. I have seen that working in this demo page (https://aminabedi68.github.io/Mikhak/) though it may be hard to spot. Why is that? Is there something about the ordering of OpenType features which causes this behavior, or is there a bug in the font processing code? Best, MHB

lmt_outline
by Mohammad Hossein Bateni 12 Mar '21

12 Mar '21

Hello, Hans said he's in the metapost mode now :) I have used lmt_outline in the following example and it is really an improvement over the previous outline "effect" because one can set the fillcolor and drawcolor separately. (that was not possible before, right?) \starttext \definedfont[dejavusansmono*arabic] \setupalign[r2l] \startMPcode draw lmt_outline [ text = "سلام", drawcolor = "red", fillcolor = "white", kind = "reverse", align = "r2l", ] scaled 3mm; \stopMPcode \stoptext 1. This works well on a plain background. I can specify the background color in fillcolor and get the outline effect. When the background is an image, this does not work too well. Can we use some clip trickery to allow for "transparent" fill? Ideally I want to set the fillcolor to a special value that would lead to only the outlines drawn. Now you'd say, that was already available via the outline "effect" before. Not quite. If a character is formed by more than one curve in the font, then we'd see some lines drawn inside the character. The new lmt_outline mechanism allows one to paint over those. Which brings me to the next problem. 2. The current mechanism draws/fills the characters one by one. In Farsi/Arabic where we have joint characters, the boundaries of letters gets drawn even in the new mechanism. See the attached PDF of the above MWE. The text consists of four characters, the 2nd and 3rd form a ligature which is joined to the 1st character. The 4th char is not joined and stands alone. Now you see the red connection between the 1st char and the ligature following it. It would be nice if the text was allowed to be processed as a whole (or at least be broken into space delimited pieces) which is drawn and then filled. Thanks, MHB

Escaping reserved/problematic characters
by Benct Philip Jonsson 11 Mar '21

11 Mar '21

In a program I'm writing I have a function for escaping characters which are reserved or problematic in LaTeX. I would like to have a corresponding function for ConTeXt, so I'm wondering which ones are different/superfluous/missing from a ConTeXt perspective in the following list (sorry about the formatting!): '{': "\\{" '}': "\\}" '_': "\\_" '%': "\\%" '#': "\\#" '$': "\\$" '&': "\\&" '`': "\\textasciigrave{}" '^': "\\textasciicircum{}" '~': "\\textasciitilde{}" '\\': "\\textbackslash{}" '|': "\\textbar{}" '<': "\\textless{}" '>': "\\textgreater{}" '[': '{[}' ']': '{]}' Note that I'm not looking for accented letters, Unicode quotes and dashes etc. I'm assuming that people in the year 2021 are using an UTF-8-aware engine (and my corresponding HTML escape function similarly caters only to & < > " '). TIA, /Benct

ConTeXt, KeenWrite, Markdown, and XHTML
by Thangalin 06 Mar '21

06 Mar '21

How would you convert the first class attribute of XHTML div elements to ConTeXt LMTX-specific start/stop environments? For example: <div class="poem dark"> <div class="stanza"> Whose woods these are I think I know. </div> <div class="stanza"> And miles to go before I sleep. </div> </dv> Becomes (the equivalent of?): \startpoem \startstanza Whose woods these are I think I know. \stopstanza \startstanza And miles to go before I sleep. \stopstanza \stoppoem In case this is an XY problem, background details follow. In a nutshell: convert a processed Markdown file that includes interpolated variables, arbitrary classes, and output from R functions into a format that ConTeXt can typeset. Background Details Pandoc's fenced div syntax is now supported by my text editor, allowing users to write "paragraph classes" in Markdown, such as: ::: {.poem .dark} ::: stanza Whose woods these are I think I know. ::: ::: This gets converted to XHTML (as shown above), which is to be rendered using ConTeXt LMTX. Rendering via ConTeXt needs the following tool chain: Editor (.md) -> run Pandoc (.tex) -> run ConTeXt (.pdf) Generating XHTML means Pandoc can be removed, simplifying the chain: Editor (.md -> magic -> .xhtml) -> run ConTeXt (.pdf) The Lua code to generate start/stop environments with Pandoc is described in Part 8 of my Typesetting Markdown series. https://dave.autonoma.ca/blog/2020/04/28/typesetting-markdown-part-8/#annot… The XML-MKIV documentation shows how to map a specific setup to a particular attribute: \xmlsetsetup{demo}{resource[@type='figure']}{xml:demo:figure} In Schmitz' XHTML-oriented My Way from 2010 there's a getmeas Lua function defined on page 9 that parses a width attribute. That's great for the opening div, but how would you close/stop the correct environment for nested divs? Would ConTeXt automatically track these on a stack, for example? Additional Ideas Given that the text editor converts Markdown to XHTML and has an XSLT engine, the following is possible: Editor (.md -> .xhtml) -> XSLT (.tex) -> run ConTeXt (.pdf) Piping XHTML directly into ConTeXt would be ideal, though. Well, piping CommonMark plus fenced div extensions to ConTeXt would be optimal, but my understanding is that support isn't quite there yet. Aditya wrote a Markdown filter that runs: pandoc -t context -o \externalfilteroutputfile\space \externalfilterinputfile This still needs Pandoc, though. There's also a dependency-free Markdown module. A few problems though. First, the module isn't ported to ConTeXt LMTX, yet? Second, it doesn't support element attributes beyond enabling content slicing. (Third, the module has LaTeX support tightly bundled within, which bloats a pure ConTeXt solution.)

conditional formatting, checking the context (SOLVED)
by Henning Hraban Ramm 06 Mar '21

06 Mar '21

Hi, in the example below I’m using a custom highlighting macro in titles. Now I don’t want this highlighting in the ToC or in bookmarks (in my real world example the changes affect bookmarks, not in the MWE).

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

tex live code freeze
by Hans Hagen 05 Mar '21

05 Mar '21

Hi, The 2021 texlive code is currently being frozen. This means that Mojca will check-in the current context release right before tl gets deep frozen. The MKII code (mkii and mpii files) hasn't changed so it should still work well with pdftex and xetex although I admit that I haven't checked to what extend updates to those engines have side effects for context, but I assume none. Let me know if there are problems. The MKIV code (mkiv, mkvi, mpiv, lua files) has changed but not much, mostly as a side effect of the code split and move to LMTX where the focus is on now. There have been recent changes in the metafun code, but new functionality is LMTX only, simply because we use an extended library (more features). Of course there have been some bug fixes to MKIV and if you think more (bugs) should be fixed let us know. The yearly texlive release is also the 'official' yearly current release but of course after that there will be updates when needed. In these updates we don't distinguish between betas and currents: we dropped that some time ago because it was only confusing. Last/this year much of LMTX (mkxl, mpxl, lmt files) already got split and I expect that this year all the lua and mp files also will be independent so that at some point we have a more or less frozen MKIV that uses luatex (which doesn't change fundamentally apart from fixes so we don't need to adapt code to it i.e. MKIV should keep working just like MKII does with pdftex; updates to for instance fonts and languages will be applied). I get the impression that most users already moved to LMTX which helped getting it in the state it is now (thanks for all the testing). Although MKII/MKIV serves a reference for functionality, new stuff got and gets added to LMTX. I could backport some but it probably makes no sense (some is probably easy). There is of course untested code like the overload protection mechasnisms but I have that enabled on my machine (users can do that too) so I can notice side effects. The new engine (luametatex) doesn't change much. Recent changes are mostly cosmetic and I don't expect many more fundamental additions, but who knows ... (not all in there is yet used extensively) and maybe context users have interesting demands that trigger extra stuff (read: challenges me). So apart from new trickery at the tex macro end, we also reach a more stable state in LMTX. Soon I'll pick up some todo's. Some users want parallel stuff (keeps coming up), I also want to see how we can do more metafun - let me know what is missing as I'm currently in metafun mode - and go over some older lua code that started as experiment but hasn't been checked recently. I also want to cleanup the export code a bit but it's kind of boring to do and maybe we should ditch some pdf backend functionilty that adobe dropped from its viewers. And there are always manuals to complete / update ... Anyway, the current LMTX release is also a kind of yearly snapshot. So, if there is some last minute stuff that needs to be done to context MKII and MKIV before the tl code freeze, let us know.

TEXpage does not fit \placetable & \recurselevel always zero
by Jacob Kauffmann 05 Mar '21

05 Mar '21

Dear list, thank you very much for the help so far. I have two problems understanding the output of the code below. I am using version 2021.02.23 17:47. (1) The TEXpage is cut off after ~40 lines. Normally, the page is extended to fit its content. It's probably related to \placetable which I only use here because I need a centered table. I can set the height of the page manually, but the whole purpose of using TEXpage was to avoid that. (2) \recurselevel is always zero in the output. Normally, it counts the iterations. This issue is not relevant for my actual use-case, but I found that when writing the MWE. Best wishes, Jacob Kauffmann \setupTEXpage[width=10cm] \startTEXpage \placetable[force,none]{}{% \starttabulate[|c|c|] \NC A \NC B \NC\NR \HL \dorecurse{50}{\NC \expanded{\recurselevel} \NC \recurselevel \NC\NR} \stoptabulate } \stopTEXpage \stoptext

LMTX 2021.03.02 | cross reference to an external file | \pagereference
by Richard Mahoney 05 Mar '21

05 Mar '21

Readers, I'm working on a couple of volumes of papers set up and generated separately (though within the same project). Some of the papers in the second volume make cross references to papers in the first. Now this is working well so long as the reference is to the details associated with, say, a chapter, using \about, \in, and \at. Its doesn't seem to work though with \pagereference: no page number appears in the PDF whatsoever. I have been following the material here: https://wiki.contextgarden.net/References#References_to_an_external_file I'm wondering then ... do cross references to an external file work with \pagereference?

Genealogy and context
by David van Diepen 03 Mar '21

03 Mar '21

Hello, My son is very much interested in genealogy. He already has collected information on thousands of people. Now it would be nice to be able to present this information in the form of a book. There is a possibility to have this done by a commercial service, however then it's not possible to adapt the format or to insert custom text. Media can be added but not in the way we like it. Genealogical information is stored as structured data. I have added a fragment of an Gramps XML file below. In such a file there are events, people, families and other groupings of data and these are linked by handles. What we would like to produce is a book with a number of blocks on every page describing a family: Father, mother, dates of birth and death, date of marriage, occupations and children. It would also be good it there are references to the grandparents. My question is: Where should I get started with a project in which a document is generated automatically from data? As far as I know context should be very suitable for this but I don't have any experience with this. Until now I've used context to make documents without any data being added automatically, except for the bibliography. Thank you in advance, David van Diepen Example Gramps XML file is below: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE database PUBLIC "-//Gramps//DTD Gramps XML 1.7.1//EN" "http://gramps-project.org/xml/1.7.1/grampsxml.dtd"> <database xmlns="http://gramps-project.org/xml/1.7.1/"> <header> <created date="2021-02-03" version="5.1.2"/> <researcher> </researcher> </header> <events> <event handle="_eaa1eb8157f4e812f219719a7b" change="1612382260" id="E1746"> <type>Birth</type> <dateval val="1886-05-01"/> <place hlink="_eaa1eb79a6e5b1f282813dc5826"/> <citationref hlink="_eaa1eb815867f8610a89cf6ce74"/> </event> <event handle="_eaa1eb8158f53693508394c0c48" change="1612382260" id="E1747"> <type>Death</type> <dateval val="1886-05-18"/> <place hlink="_eaa1eb79a6e5b1f282813dc5826"/> <citationref hlink="_eaa1eb815964a4157b91beb0bcb"/> </event> <event handle="_eaa1eb99c423cc862cf41d591a7" change="1612382270" id="E6977"> <type>Marriage</type> <dateval val="1883-03-11"/> <place hlink="_eaa1eb79a6e5b1f282813dc5826"/> <citationref hlink="_eaa1eb99c4870fe758b76275a86"/> </event> </events> <people> <person handle="_eaa1eb8157e1aa01007c5a920d1" change="1612382260" id="I0987"> <gender>F</gender> <name type="Birth Name"> <first>Catharina</first> <surname>Geldof</surname> </name> <eventref hlink="_eaa1eb8157f4e812f219719a7b" role="Primary"/> <eventref hlink="_eaa1eb8158f53693508394c0c48" role="Primary"/> <childof hlink="_eaa1eb79b3313e7e3c96019665c"/> </person> <person handle="_eaa1eb7a37226ca41e414cd2f36" change="1612382258" id="I0049"> <gender>M</gender> <name type="Birth Name"> <first>Cornelis</first> <surname>Geldof</surname> </name> <eventref hlink="_eaa1eb7a3735b3bd6acb1a5aa1c" role="Primary"/> <eventref hlink="_eaa1eb7a3831437df21bf3f6924" role="Primary"/> <eventref hlink="_eaa1eb7a3942a2fb185331a9edf" role="Primary"/> <childof hlink="_eaa1eb7a39a2dfce87e06b0adab"/> <parentin hlink="_eaa1eb79b3313e7e3c96019665c"/> </person> <person handle="_eaa1eb7a3a54ad77d5f29a821c9" change="1612382258" id="I0050"> <gender>F</gender> <name type="Birth Name"> <first>Maatje</first> <surname>de Voogd</surname> </name> <eventref hlink="_eaa1eb7a3a731714abad9183560" role="Primary"/> <eventref hlink="_eaa1eb7a3b74da1e4ff36adcaab" role="Primary"/> <eventref hlink="_eaa1eb7a3c8685236291abfcbc9" role="Primary"/> <childof hlink="_eaa1eb7a3cd3853b21c39baab9a"/> <parentin hlink="_eaa1eb79b3313e7e3c96019665c"/> </person> </people> <families> <family handle="_eaa1eb79b3313e7e3c96019665c" change="1612382261" id="F0016"> <rel type="Married"/> <father hlink="_eaa1eb7a37226ca41e414cd2f36"/> <mother hlink="_eaa1eb7a3a54ad77d5f29a821c9"/> <eventref hlink="_eaa1eb99c423cc862cf41d591a7" role="Family"/> <childref hlink="_eaa1eb79b0b8526fca40e502ca"/> <childref hlink="_eaa1eb815521c4281a23ee688d2"/> <childref hlink="_eaa1eb8157e1aa01007c5a920d1"/> <childref hlink="_eaa1eb815a9647c05a8560739f3"/> <childref hlink="_eaa1eb815d632b4145a6a964cd1"/> <childref hlink="_eaa1eb81603107eb844e1d0a1ce"/> <childref hlink="_eaa1eb816306fa3946fe9a88f1b"/> <childref hlink="_eaa1eb81651258b725548dba1dc"/> <childref hlink="_eaa1eb8167243fc0ae5b90986c1"/> <childref hlink="_eaa1eb818cf2e229c88b97b192e"/> <childref hlink="_eaa1eb818ec579ca7141aa0efbe"/> <childref hlink="_eaa1eb8191314350b99ec3ade67"/> </family> </families>

lmtx update / teaser
by Hans Hagen 02 Mar '21

02 Mar '21

Hi, I uploaded a new lmtx. As I'm currently going through the metafun todo files I ended up at the fancy shape part (parshapes) running over multiple paragraphs and decided to provide a (kind of low level) interface that integrates that. The example code is a few decades old but still works ok (i might try to improve them a bit some day). Anyway, here is a teaser: \starttext \startuseMPgraphic{circle} lmt_parshape [ path = fullcircle scaled 136mm, offset = 2mm, bottomskip = - 1.5LineHeight, ] ; \stopuseMPgraphic \start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=cycle]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}}\par {\darkgreen \samplefile{tufte}}\par {\darkblue \samplefile{tufte}}\par {\darkcyan \samplefile{tufte}}\par {\darkmagenta \samplefile{tufte}}\par \stopshapedparagraph \stop \page \start \startshapedparagraph[list=circle,mp=circle,repeat=yes,method=repeat]% \setupalign[verytolerant,stretch,last]\dontcomplain {\darkred \samplefile{tufte}} {\darkgreen \samplefile{tufte}} {\darkblue \samplefile{tufte}} {\darkcyan \samplefile{tufte}} {\darkmagenta \samplefile{tufte}} \stopshapedparagraph \stop \stoptext The interface is still somewhat rough (no grouping for instance, not a real envrionment so that might change) but seems to work ok. One can also go the tex route and say: \startparagraphshape[test] left 1mm right 1mm left 2mm right 2mm left 3mm right 3mm copy 8 left 4mm right 4mm left 5mm right 5mm left 5mm hsize 10cm \stopparagraphshape or \startparagraphshape[test] left 1mm right 1mm right 3mm left 5mm right 5mm repeat \stopparagraphshape or \startparagraphshape[test] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm \stopparagraphshape or \startparagraphshape[test-repeat] both 1mm both 2mm both 3mm both 4mm both 5mm both 6mm both 7mm both 6mm both 5mm both 4mm both 3mm both 2mm repeat \stopparagraphshape and use that with: \startshapedparagraph[list=test] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph or \startshapedparagraph[list=test-repeat] \dorecurse{8}{\showparagraphshape\samplefile{tufte} \par} \stopshapedparagraph Some more info is in the lowlevel-paragrsph document (part of the low level series). This kind of features falls into the category 'fancy' (no one reqtested it), nice for posters and covers. It might evolve depending on needs for fancy features, but as said, it's currently a side track of metafun, so it's also in the category 'fun'. It's code for 'controlled' usage.

Project Structure - inheritance rules for environments
by denis.maier＠ub.unibe.ch 01 Mar '21

01 Mar '21

Hi, I'm just having a look a project structure again. I am using the example given in the wiki: https://wiki.contextgarden.net/Project_structure, i.e., in my component I'm linking to the product, but not to the project. Now I was expecting that the component inherits the environment set in the project via the product. The wiki currently explains: "If you tex (compile) one single component (e.g. a chapter of a book) or product (e.g. one volume of a magazine), the environment file of the project is used." That does not seem to be the case here. Can anyone confirm this? Is this a bug or does the wiki needs to be revised? Best, Denis

Make LMTX load a custom library
by Lukas/ConTeXt 01 Mar '21

01 Mar '21

Hello, suppose having a custom DLL (actualy a Lua module) in: d:\Lukas\Lua\54\WinCon.dll How exactly should I alter the path specification so LMTX be able to load WinCon.dll? My trials - without success so far - are: 1. Alter LUA_CPATH before running Ctx, so something like: ---- (command line) set LUA_CPATH=d:\Lukas\Lua\54\?.dll;%LUA_CPATH% context.exe test.tex ... ---- 2. Alter LUAINPUTS before running Ctx, so something like: ---- (command line) set LUAINPUTS=%LUAINPUTS%;d:\Lukas\Lua\54\?.dll;%LUA_CPATH% context.exe test.tex ... ---- 3. Changing the path at runtime, so something like: ---- test.tex \startluacode package.cpath = package.cpath .. ";d:/Lukas/Lua/54/?.dll" require "MyLib" \stopluacode ---- But I'm still getting errors like: " ... token call, execute: ...TX/tex/texmf-context/tex/context/base/mkiv/l-sandbox.lua:180: module 'WinCon' not found: no field package.preload['WinCon'] no file 'd:\Lukas\Lua\WinCon.lua' no file 'd:\Lukas\Common\Statics\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\stdlib\modules\WinCon.lua' no file 'd:\Lukas\Lua\3rdParty\LuaXML\WinCon.lua' no file 'C:\Program Files (x86)\Lua\5.1\lua\WinCon.luac' no file 'd:\Lukas\Lua\Geom' ... " Surprisingly, loader tries to locate a *.lua* only, whilst here I nedd to load a .dll; and in genereal case, .lua, .luac and .dll may be required. So - how to specify the path correctly, be it on the command line or within a .tex (LMTX run-time)? Best regards, Lukas

by a badin 28 Feb '21

28 Feb '21

Dear gardeners, I'm new to ConTeXt and would like to share a possible bug with you. If I have the \setupbackend[export=example.xml,css=example.css] entry in my .tex file, then my bibliography renders in a strange way (text copied from pdf): 1 bfldcategoryarticle: [author: Andrej Arrow] [journal: MAPS] [keywords: context] [pages: 2-8] [title: The Font Name Mess] [volume: 40] [year: 2010] If I remove or comment that entry out, then the bibliography renders OK (copy from pdf): 1 A. Arrow, “The Font Name Mess”, *MAPS *40, 2-8, 2010. my .tex source is: % \setupbackend[export=example.xml,css=example.css] \usebtxdataset[default][ref.bib] \starttext \cite[Arrow][Arrow] \placelistofpublications \stoptext my ref.bib file: @ARTICLE{Arrow, author = {Andrej Arrow}, title = {The Font Name Mess}, journal = {MAPS}, year = {2010}, volume = {40}, pages = {2-8}, keywords = {context}, } Hope this helps, best, Andrej -- Andrej Badin +31 6 82 23 50 33

Incorrect css reference in exported html file
by Aditya Mahajan 28 Feb '21

28 Feb '21

Hi, This message is prompted by a bug report for t-vim (https://github.com/adityam/filter/issues/43) but the issue is more general. Whenever, `cssfile` in `\setupexport` points to a file now in $PWD, the reference to the file in the exported CSS is incorrect: Consider the following directory tree: test.tex styles/mystyle.css where test.tex is: ``` \setupbackend[export=yes] \setupexport[cssfile=styles/mystyle.css] \starttext \startparagraph This is a test \stopparagraph \stoptext ``` and styles/mystyle.tex is (the content doesn't matter, listing it for completeness): ``` paragraph, p, div.paragraph, div.p { color : red ; } ``` I am attaching a zip file for convenience. When I compile the above file, I get (selective lines from output) ``` backend > export > copying styles/mystyle.css ... backend > export > adding css reference 'styles/styles/mystyle.css' ``` Indeed, the styles/mystyle.css file is copied to `test-export/styles/mystyle.css` but the reference in `test-export/test-export-div.html` is: ``` <link type="text/css" rel="stylesheet" href="styles/styles/mystyle.css" /> ``` Note the repeated styles/styles. What is happening is that while copying the file, context is using (in back-exp.lua): local source = addsuffix(cssextra[i],"css") local target = joinfile(stylepath,basename(source)) while for reference, context is using: result[#result+1] = replacetemplate(csspreamble, { filename = cssfile }) extras[#extras+1] = replacetemplate(cssheadlink, { filename = cssfile }) Shouldn't the last part be filename=basename(source) to get the right name? Without that whenever the value of cssfile is a file in another directory, the css reference in the exported html file will be incorrect. In case anyone is interested, this manifests in t-vim as follows. The t-vim module includes a pre-generated css file which provides the color and style values for the default color schemes. The module provides a macro \vimcssfile, which is the complete path of the file (basically the value of `resolvers.resolve("full:vimtyping-default.css")`). The intended usage is: \usemodule[vim] \setupbackend[export=yes] \setupexport[cssfile=\vimtypingcssfile] ... In this case, the css file is correctly copied to the '\jobname-export/styles` directory. but the `\jobname-div.html` file contains a unusable reference: ``` ... <link type="text/css" rel="stylesheet" href="styles/opt/luametatex/texmf-modules/tex/context/third/vim/vimtyping-default.css" /> ``` In principle, I can work around this in t-vim but I think that this will impact others as well. Thanks, Aditya

\hbox to ... equivalent in ConTeXt (\framed)
by Jairo A. del Rio 26 Feb '21

26 Feb '21

Hi list. Is there an interface for \hbox to <size> via framed? I think it's not the ConTeXt spirit to do something like \framed[offset=0cm]{\hbox to 10cm{Uno dos tres}} where spacing is stretched so all the available space is filled, so I want to know about a better way. Thank you beforehand. Cordially, Jairo

Hello, after I renewed ConTeXt MkIV, I started to get the following warning: " ... luatex warning > nodes: unable to store reference from lua in tex ...

Help figuring why long document stops short in xml export
by Christoph Hintermüller 24 Feb '21

24 Feb '21

Hi What command line parameters, trackers etc I should activate when i want to figure why my document lacks content worth of several pages in xml export while the pdf which is created in parallel contains all pages. I'm using mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: <prefixpath>/tex/texmf- context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2021.02.14 16:39 mtx-context | main context file: <prefixpath>/tex/texmf- context/tex/context/base/mkxl/context.mkxl mtx-context | current version: 2021.02.14 16:39 Would switching to lmtx may be helpful in at least figuring why or be the only known solution? The Document it self is my lecture notes which are about 125 Pages long. The xml export ends at Page 63. Are there any known commands which can cause exporter to give up early and thus should in export be avoided or be put in mode dependent block hiding them form exporter. Any hint what i should, would have to check and how to hopefully grabe any hint where to amend the document to get full output. Currently i have not made images mode dependent (pdf:metapost, xml:png/svg). Could that be a reason why exporter finally ends document early? I'm sorry to be so clue less to not be able to provide more information. The document it self is too big to be posted and i do not want to make it public anyway, but if required i can provide a share link. Best Christoph Hintermüller

Possible problem with context using the ARM 64bit download for Apple Silicon M1
by Keith McKay 23 Feb '21

23 Feb '21

Hi all I have been using ConTeXt (X86 64bits) on my mac mini Apple Silicon M1 and it works well using Rosetta translation for the M1. I recently installed the ARM 64bits version (separately from the X86 64bits version) which I assume does not require translation using Rosetta. However I had a error with the lmt_shade command in the ARM 64bits ConTeXt verson but not in with the X86 64bits version of ConTeXt. The MWE is shown below. This is actually taken from the LuaMetaFun manual. I also noticed that some figures are missing in the manual (Chapter 7, Shade) which is part of the ARM 64bit tree but not in the manual in the X86 64bits tree. Best Wishes Keith McKay Hamilton, Scotland. %%%%%%%%%%%%%%%%%%%%%%%%% \setuppapersize [A4, portrait] \usecolors[crayola] \starttext \startMPpage StartPage; width := PaperWidth ; height := PaperHeight ; unit := cm ; definecolor [ name = "MyColor3", r = 0.22, g = 0.44, b = 0.66 ] ; definecolor [ name = "MyColor4", r = 0.66, g = 0.44, b = 0.22 ] ; draw lmt_shade [ path = fullcircle scaled 4cm, direction = "right", domain = { 0, 2 }, colors = { "MyColor3", "MyColor4" }, ] ; StopPage; \stopMPpage \stoptext %%%%%%%%%%%%%%%%%%%%%%%% Here is the error taken from the log <snip> system > system > ConTeXt ver: 2021.02.20 16:50 LMTX fmt: 2021.2.21 int: english/english system > system > 'cont-new.mkxl' loaded <snip> metapost > initializing number mode 'scaled' metafun > log > metafun > log > error: Not a cycle metafun > log > metapost > log > <to be read again> metapost > log > withprescript metapost > log > <argument> ...asparameter"vector":center_a:=point(getparameter"vector"1)of.mfun_shade_path;center_b:=point(getparameter"vector"2)of.mfun_shade_path;fi.fill.mfun_shade_path.withprescript metapost > log > "sh_domain="... metapost > log > image->begingroup.save.currentpicture;picture.currentpicture;currentpicture:=nullpicture;(TEXT3) metapost > log > ;currentpicture.if.str(SUFFIX2)<>"":shifted(mfun_labxf(SUFFIX2)*lrcorner.p+mfun_labyf(SUFFIX2)*ulcorn... metapost > log > lmt_do_shade->...ve="circular":draw.fullcircle.scaled(radius_a)shifted.center_a.dashed.evenly;draw.fullcircle.scaled(factor*radius_b)shifted-center_b.dashed.evenly;fi.fi.popparameters;) metapost > log > endgroup metapost > log > <scantokens> lmt_do_shade metapost > log > metapost > log > <*> ... name = "MyColor4", r = 0.66, g = 0.44, b = 0.22 ] ; draw lmt_shade [ path = fullcircle scaled 4cm, direction = "right", domain = { 0, 2 }, colors = { "MyColor3", "MyColor4" }, ] metafun > log > metafun > log > That contour should have ended with '.. cycle' or '& cycle'.

Arbitrary equation tags... again
by Jairo A. del Rio 23 Feb '21

23 Feb '21

Hi. list. Is it possible to assign an arbitrary equation tag in ConTeXt? I've seen solutions here; https://tex.stackexchange.com/questions/400257/tag-equation-in-context-with… but none of them works as expected (either the formula counter is still incrementing with arbitrary conversions or cross-references don't work). I imagine some things have changed in 2021 and I hope a better solution is feasible nowadays. Best regards, Jairo

metafun
by Hans Hagen 20 Feb '21

20 Feb '21

Hi, When making sure that the metafun manual processes with lmtx (where we have sometimes different implementations of macros) I also checked performance. When we started with this manual, it was still MKII time so we either had direct calls or inbetween calls. Especially multiple runs could take a while (many minutes, iir some 15 depending on how it was run). That was no fun. In mkiv with luatex and the built in mp library this dramatically went down to 18.1 seconds for one run and 14.2 seconds for luajittex, for 428 pages. This not bad considering that a lots of features are used: thousands of mp images, a bunch of external images, many fonts, plenty of buffers, positioning, color, hyperlinks, backgrounds etc. This document uses plenty of lua so that is why we gain a lot with luajittex. In lmtx where we dropped jit and have a less performing backend we expect to need more runtime but in the meantime we're quite okay. Not only the engine is faster, but also some low level macros benefit a bit from new features. I don't know how much lua speedup plays a role but probably not that much. For 448 pages (some 20 more than we had before) we now need 16.5 seconds and 15.7 when we use the compact font mode. So we're halfway between luatex and luajittex now. More than 3 seconds of the runtime is for metapost. (I use the machine as before.) Hans PS. If all the stories are true is should be 1 second on a modern apple at which point differences in measurements become noise but I cannot check that. Some day I might check it on a rpi 4. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

In general, tweaking the machinery can give different results and i guess that hardly any user can make consistent claims about what is better. It all depends on what one deals with. (The keyword is suboptimal, it kind of tells what happens but on the other obscurew what really goes on: always forcing a first hyphenation pass when breaking lines.)

set fallback in \definefont
by Mohammad Hossein Bateni 16 Feb '21

16 Feb '21

Hi, Is there a way to set the fallback for fonts when we define them not as a typescript but using \definefont? \definefont[MyFont][Font.otf*MyFeatures] Is there a default fallback one can specify? Is simplefonts module deprecated or discouraged now? When we define a font via typescript commands, we can specify rm, ss, tt, mm, hw and cg shapes for it. Can we add arbitrary styles? For example, I would use this for quotations, headings, etc. Currently, I either have to spare ss or use \definefont for such scenarios. Thanks, --MHB

temporary changes to the layout - \startlocal undefined
by Werner Hennrich 16 Feb '21

16 Feb '21

Hello Everybody, I need to increase my header's space temporarily and according to pg 99 of context_an_excursion "\startlocal ... \stoplocal" is the way to go - unfortunately my LMTX (2021.02.02 15:49) disagrees: \setuppapersize[A4][A4] \setuplayout[ ... header=15mm, ... ] \starttext \input tufte \page \startlocal \setuplayout[header+=20mm] \input tufte \stoplocal \page \input tufte \stoptext This fails: tex error > tex error on line XX in file ./local-layout.tex: Undefined control sequence XX >> \startlocal Do I need to load something in order to use this? Or has it been completely removed? And if so, is there a new alternative method to do the same thing? I was unable to find anything on this topic except https://www.mail-archive.com/ntg-context@ntg.nl/msg63602.html which raises the same question already in 2012 but never answers it IMHO. Thank you very much, Werner

verify if you are already postponing notes
by mf 15 Feb '21

15 Feb '21

Dear list, I'm typesetting XHTML and there is a couple of cases (tables and math), where I use \postponenotes ... \flushnotes in both their XML setups. The problem arises when I have math inside the cell of a table, so I get those commands nested: \postponenotes % <table> element \postponenotes % <span class="math"> element inside a cell \flushnotes % </span> closing math \flushnotes % </table> closing table With CSS selectors or XML machinery I can find those corner cases, but something like this would be better because more general: \doifnotpostponingnotes{\postponenotes} \dofipostponingnotes{\flushnotes} Is there a way to define those \doif... macros?

tikzpicture in margin
by Jigé 15 Feb '21

15 Feb '21

Hi all. I'm trying to place a TikZ picture in the margin. Here is a small example: \usemodule[tikz] \setuplayout[backspace=4cm, topspace=2cm, height=middle] \starttext \input{lorem} \margintext{I have discovered a truly marvelous proof ... but this margin is too narrow to contain it.} \input{lorem} \inmargin{\externalfigure[cow] [width=\marginwidth]} % The above works. % The following does not: \input{lorem} \inmargin{ \starttikzpicture \draw[gray] (-2,0) grid (2,2) ; \draw plot [domain=-2:2, samples=50, smooth] (\x,{\x * \x}); \stoptikzpicture } \stoptext -> Undefined control sequence I tried using \startfigure, \hbox... no success. Actually the command \startmarginblock ... \stop... described in the ConText reference works with a TikZ picture. But the picture, in the margin, gets near the top of the page. I don't understand the meaning of the options (especially the difference between `location' and `align'). And is it `\setuppagenumbering[alternative=doublesided]'-aware ? Example: \usemodule[tikz] \setuplayout[backspace=4cm, topspace=2cm, height=middle] \setuppagenumbering[alternative=doublesided] \starttext \input{lorem} \inmargin{\externalfigure[cow] [width=\marginwidth]} \pagebreak \input{lorem} \input{lorem} \blank We would like the picture to go the the left of this paragraph. \setupmarginblocks[location=left,align=inner] \startmarginblock \starttikzpicture[scale=0.2] \draw[gray] (-2,0) grid (2,2) ; \draw plot [domain=-2:2, samples=50, smooth] (\x,{\x * \x}); \stoptikzpicture \stopmarginblock \stoptext Best regards

scope
by Hans Hagen 14 Feb '21

14 Feb '21

Hi, When you allocate a new register (with e.g. \newdimen) that is always a global definition (kind of a tex tradition). As a (likely to stay) experiment I added \newlocaldimen \foo \setnewlocaldimen \foo 123pt and comparable helpers. Some more can be found in lowlevel-scope.pdf in the distribution. The idea is that users who write their own macros that need 'variables' can define them locally without the danger for clashing with system ones (or each others macros). Actually, global assignments only affects that variable, so one can do \bgroup \newlocaldimen\foo \bgroup \global\foo=456pt \egroup ... use \foo \egroup Best use names like \mydimena etc in order nnot to clash with system ones (that can be protected against overload). In spite of redefinitions each time a macro using it gets expanded, performance is quite okay. It falls in the category "interesting hacks but maybe not needed because never asked for", but on the other hand, sometimes availability creates retrospective demand. (I also did \newlocalread and added some extra random access hackery to \read, so who knows what users will abuse that feature for.)

parsing multi-valued parameters
by Werner Hennrich 13 Feb '21

13 Feb '21

Hello everyone, please can you give me pointers on how to easiest parse multi-valued \dummyparameter{...} like in \something[...,weather={sunshine, rain, hail},...] so that I can test for e.g. rain, sunshine, wind, hail, mist, fog, storm etc, each if it is present or not? ...so I can keep my number of parameters down and my parameter list as simple as possible. I have no idea what to search for in the docs or (better) in the test cases / samples. Would be great if you could just let me know where to look or what to sarch for Thank you very much! Werner

Loop?
by Angel M Alganza 13 Feb '21

13 Feb '21

Hello: I am trying to print a list of names always followed by the same info (generated by a new command). At the moment, I have all the names followed by the command like so: Person Number One \mycommand Person Number Two \mycommand Person Number Three \mycommand Person Number Four \mycommand Person Number Five \mycommand . . . I'd rather have the list of people stored somewhere (a list? an array?) and loop through it and then inserting \mynewcommand at compilation time. That way, when I need to replace the list of people with a new one, I'd just do that instead of building the above structure again and again. Is it possible to do that with just ConTeXt or would I need to resort to Lua. I guess it should be possible both ways, but I haven't figure out how to do it. Any pointer, please? Thank you so much in advance. Cheers, Ángel

new upload

Hi, I uploaded a new version. I'v enow tagged all public macros (not that anyone will notice) as a step in the overload protection effort. If you want to get an idea about what we're talking of you can process s-system-macros.mkxl This file is mostly for Wolfgang and me when we update to lmtx, but it's used to identify 'todo's. We're talking tex as well as metapost here. In the process some orphan (mkii) stuff has been removed and a few small fixes applied (in code that probably no one ever encounters anyway). In lmtx I also updated the stixtwo fonts (new names again) and added libertinus (for Tomas Hala to test).

LMTX bug? \completelistofabbreviations

issue printing with Acrobat?

Dear list, I have the following sample: \setuppapersize[A4, landscape] \setupinteractionscreen[option={landscape, paper}] \starttext \dorecurse{2} {\startmakeup[page][pagestate=start, align=middle] \dontleavehmode \scale[width=.8\textwidth]{middle} \stopmakeup} \stoptext Selecting paper in option from \setupinteractionscreen also sets (printing) orientation to auto. I couldn’t print the resulting PDF generated from the code above without having to set orientation to landscape (in Acrobat’s printing dialog). Otherwise, I was getting wrong orientation in printed pages. Printing was wrong in both printers I tried. Acrobat DC (reader) version is Acrobat DC (2021.001.20135). I was using both MkIV and latest LMTX. I think there might be a bug in latest Acrobat.

Twenty One versus Twenty-one
by jbf 11 Feb '21

11 Feb '21

Am currently dealing with a book that has twenty-one chapters, and the author (who is visually impaired) follows a range of visually impaired principles when writing and wanting things published. That's the background to my question! MWE \setuphead[chapter][ header=empty, alternative=middle, style={\ssd}, number=yes, conversion=Word, command=\MyChapterCommand, after={\blank[1cm]}, ] Problem is, when we get to chapter Twenty-one (which is the correct way to write it in English) it gives me 'Twenty One'. Is there a way, in my setup, that I can force it to give me 'Twenty-one'? (note the hyphen and the lower case for 'one'). I don't think MyChapterCommand is relevant here, but just in case, this is it: \define[2]\MyChapterCommand% {\framed[frame=on,bottomframe=on,leftframe=off,rightframe=off,topframe=off,align=middle] {\vbox{\headtext{chapter} #1\blank#2}}} Julian

Centered list of authors in ToC
by jbf 09 Feb '21

09 Feb '21

I wonder if someone can assist me with the final step in a complicated Table of Contents where all items in the ToC are centred (except page numbers which continue to be on the right). Beneath each chapter title is a list of authors (Yes, there can be up to four authors per chapter!) I can successfully achieve everything (see MWE below) except for getting the list of authors to split and be centred. Because there are four of them, I would need to split them so they appear as two (centred) with the other two below(also centred). Here is my MWE for the essential bit (which is then called in as textcommand=\SectionTocEntry in \setuplist[chapter], obviously): \define[1]\SectionTocEntry{% #1\crlf% title \midaligned{\doifnot{\structurelistuservariable{author}}{}{\structurelistuservariable{author}}}% } My problem is that at the moment, the four authors appear on a single line, so I end up with: My chapter title Mickey Mouse, Donald Duck, Uncle Scrooge, Minnie Mouse [p. 1, but in fact, Minnie Mouse runs across the page number!] What I want instead is: My chapter title Mickey Mouse, Donald Duck Uncle Scrooge, Minnie Mouse [p. number] Back at the chapter level my code reads: \startchapter[title={Chapter title}][author={Mickey Mouse, Donald Duck, Uncle Scrooge, Minnie Mouse}]. Anyone able to help with this? Julian
