developer not verified error
by Alan Bowen 19 Nov '19

19 Nov '19

Though I was able to download the latest ConTeXt beta without any problems, my attempt to update my ConText-LMTX installation was blocked. The error message was *“mtxrun” cannot be opened because the developer cannot be verified* macOS cannot verify that this app is free from malware. Safari downloaded this file on April 29, 2019. I am not sure why this is happening and wonder if it would OK to copy mxtrun from my ConTeXt installation and replace the version in my ConTeXt-LMTX installation with it. Alan

Hello, Thanks for those precisions regarding whiping the cache. For the sake of future debugging, which mtxrun option should I run to check what is the cache-path in my personal account, having a system-wide install? Regards, Damien Thiriet

fatal error: there is no valid writable cache path defined
by Damien Thiriet 16 Nov '19

16 Nov '19

Hi, I ran into trouble with caches. First I updated the new binaries and they compiled fine under OpenBSD6.6-amd64. Then I uploaded some binaries Hans asked me to test, moved this luametatex to /usr/local/context/tex/texmf-openbsd6.6-amd64/bin/, deleted files inside /usr/local/context/tex/texmf-cache (but not texmf-cache itself, since I understand whipe as cleaning inside it) and ran mtx-run --generate then context --auto. When I tried afterwards to compile those new binaries, I get this error This is LuaMetaTeX, Version 2.01.0 resolvers > caches > fatal error: there is no valid writable cache path defined Running mtx-run --generate on my user account did not solve the problem. I certainly did something wrong. I tried to revert to the standard lmtx binaries running install.sh but those errors are still here. Regards, Damien Thiriet

Cross references to column numbers
by Oliver von Criegern 16 Nov '19

16 Nov '19

Dear list members, how can I create cross references to column numbers? I have a two column layout with column numbers in the header instead of page numbers (actually, these column numbers are calculated from the page numbers). Now I want to create a cross reference that returns the column number of the target. How can I achieve this? Of course, I can get the page number with \pagereference (for the target) and \at (for the reference), but for calculating the column number (according to what I did in the header), I would also need to know whether the target is in the left or in the right column, and I can't see how I can get this information. For an example, see the question posted by me at stackexchange: https://tex.stackexchange.com/questions/502944/context-cross-references-to-… Besides, I am wondering, regarding the generally very regular and consistent naming of commands in ConTeXt, why this is not so in the case of references. For example, to refer to a page, I need \pagereference (for the target) and \at (for the reference); to refer to a line, I need \someline (for the target) and \inline (for the reference), but only if I want it to automatically add the word "line" or something else before the number, otherwise I have to use \inlinerange. It took me some time to find that out. Wouldn't it be easier to have just one command for the target and another one for the reference, and everything else, as counters and headers to be returned, text to be added etc. to be configured by options? Best regards, Oliver.

Hi all, I am writing some maths exercises that include simplifying fractions. For that reason I would like to cross out some numbers.

Right-to-left Documents
by Marc Trius 14 Nov '19

14 Nov '19

I'm trying to create a two-sided document in an RTL language. I'd like to reverse the margins and the page flow, so that the first page has the binding on the right side, rather than on the left, and the documents display correctly in pdf readers. I posted this question on TeX Stack exchange, and was informed by Wolfgang Schuster that it is currently impossible to do. He suggested that I use \setcounter[realpage][2] to simulate a document that starts with a left page, but warned that this might cause unwanted side effects. Would it be possible to properly implement document-level right to left direction? I am not an expert ConTeXt user, but I would be happy to assist in testing as much as I am able. Thank you, Marc Trius

PDF layer links
by Philipp A. 13 Nov '19

13 Nov '19

Hi, I asked this question some time ago: https://tex.stackexchange.com/q/354731/2867 Today I found out about viewer layers. Sadly they seem to be buggy in the ConTeXt version in TeXlive 2019.52575 When I compile the following document, the “view” layer seems to gobble up the rest of the document: Hiding it makes “More text” vanish. Also, I don’t know if [state=stop,printable=yes] does what I want, i.e. being visible by default on print media. If not, how to achieve that? Best, Philipp \defineviewerlayer[print][state=stop,printable=yes] \defineviewerlayer[view][state=start,printable=no] \def\viewcolor#1#2{% \startviewerlayer[view]\color[#1]{#2}\stopviewerlayer% \startviewerlayer[print]\llap{#2}\stopviewerlayer% } \starttext Hi! \viewcolor{red}{This is only red on screen}.

new beta
by Hans Hagen 13 Nov '19

13 Nov '19

Hi, I uploaded a new beta. Apart from some fixes, the main change in lmtx is that on windows most (a few exceptions) of the mechanisms that interface to the operating system support the internal wide character model which should make the lot more robust for file names, environment variables, command line options etc that (at the tex/lua end utf8) have characters other than ascii. Another improvement in lmtx is support for ancient type 1 fonts (like the type 1 lucidas) but that's more 'being complete' than a 'real need' (when such fonts are used wiping the cache is needed). Both these (lmtx only) patches can have unforseen (by me) side effects but nothing that can't be fixed fast.

Formatting in toc

This morning, I realised what I needed to do, and it works. Before \starttext put: \define[2]\hymn{\bf Hymn #1 \hspace[big] \it #2}\par} After \starttext put stuff like \hymn{34}{We three kings} or \hymn{10}{In the bleak midwinter} etc. This does near enough what I am after: creates a template style command, and replicates formatting in toc. No doubt, there might be tweaks or even cleverer ways to improve on my efforts. Thanks to all who took the trouble to read, and consider; and especially Hraban, who took the trouble to offer a suggestion, which inspired me to think more clearly. Thanks, Calum

Help wanted: index with chapter and section numbers

10 Nov '19

Hi, In a math text book, I would like to create an index of some material where chapter and section numbers are given instead of a page number. For instance if the result « 3.2.5 Banach Fixed Point Theorem » is stated in section 2 of chapter 3, and is the fifth numbered statement in that section, I would like to create a \myindex command so that adding the command \myindex{Banach Fixed Point Theorem} at that location, I get in the index created by \myindex a line such as Banach Fixed Point Theorem 3.2.5 Is this possible?

Formatting in the toc
by Calum MacLeod 09 Nov '19

09 Nov '19

I have now found time to see if I could work out how to apply \structurelistuservariable. In short, I have to admit that I could not. I am grateful to Hraban for his encouraging response, but though I could see it was related, it seems to me not quite what I seek. The more I thought about the answer, I realised I had not explained my question in a precise manner. I am retired, and produce a weekly A5 booklet from material with which my wife (a church minister), supplies to me. I call it a pulpit manuscript. It is the entire script for her service. Included are the numbers and first line of five hymns, that are different each week. Until I gain a better understanding of ConTeXt, I shall continue to use LaTeX koma-script package for the weekly booklet. In order to make life easier for myself, I have created commands of my own. One of these commands enables me to have a template which has five instances of \hymn{} {}. If I put with the first braces pair '387', and in the second pair, 'The Lord's my shepherd' --- when LaTeX koma-script outputs the PDF, 'Hymn 387' is in bold and 'The Lord's my shepherd' is italicised. For the next hymn, it would be a different number, and different first line, but it would auto-formatted the way I want. That command is constructed in the preamble in the following way: \newcommand{\hymn}[3][Hymn]{\addsec{\rlap{\textbf{#1 #2}}\hspace}{7em}{\normalfont\small\textit{#3} }}} This places a specific gap between the hymn number and the first line as well. Not only does it format the section heading (\addsec) to have bold and italics (without bold), it formats the corresponding entry in the toc in exactly the same way. How can I make a similar command for ConTeXt, please?

Issue with text running into footnotes
by Otared Kavian 09 Nov '19

09 Nov '19

Hi all, I have a lecture note in which a few footnotes are given, but in some cases the text runs into the footnote, and it has been impossible for me to exhibit a minimal example where the issue appears. In the link https://www.dropbox.com/s/o9h0j6i21emyw2v/footnote-issue.pdf?dl=0 <https://www.dropbox.com/s/o9h0j6i21emyw2v/footnote-issue.pdf?dl=0> the issue is shown in the real case. If I remove a few lines of text before the last paragraph on th tepage shown in the above link, the issue disappears, but of course this is not a solution. I am aware that overuse of footnotes is not recommended, but in my lecture notes I have very few of them. Is there a way to prevent such conflicts between footnotes and the last lines of text on a page? Many thanks in advance: OK

Hello, OK, thanks for reaction. One more example - \text instead of ascii mode: ---- \starttext \type{%@$} A\footnote{\type{*\$% }} B\footnote{\type{*\$\% }} \stoptext ---- gives: " *\$ *\$\% " in the footnote. IOW, I cannot simply print "%": "%" at the end yields "" whilst "\%" produces "\%". Is there a simple way to prinst simple "%"? (There is probably a more clumsy way - type \letterpercent instead of % - but this is a minimal sample; in my real sample there are many "%"s to be shown as "%".)

How to define the font size of the page header?

Hi Folks, Sorry for the constant interruptions, but I can't find an answer in any of the many PDFs or webpages I can find. How do I define the font size of the page header? If I'm not using a custom font, I can call \switchbodyfont prior to calling \setuplayouttext, which, if I'm honest, seems weird, but it doesn't work if I use a custom font. eg: \definefontfamily [dejavu] [serif] [DejaVu Serif] \definefontfamily [dejavu] [sans] [DejaVu Sans] % Uncomment this and the page header font size drops dramatically. % \setupbodyfont[dejavu] % This seems to define the size of the page header, if \setpbodyfont is not called. \switchtobodyfont[50pt] \setuplayouttext [header][text] [ style=small, middletext=Page Header, righttext=\pagenumber, rightstyle=bold ] \switchtobodyfont[8pt] \starttext \input ward.tex \stoptext I half expected the 'style' property to be involved in this, but I can't get that to do anything either :-( How do I define the font size in a page header defined using \setuplayouttext ?

Bad cooperation between \unit and TABLE
by Tomas Hala 04 Nov '19

04 Nov '19

Hi all, I came across the problem with bad aligment of cells in natural tables (longer MWE below): When I use \unit for better typesetting of units, lines 6, 6a, 8 and 9 are sloppy-aligned -- first, the alignmentcharacter is ignored, secondly the very huge space appears between e.g. m and 2. It seems that it happens at any time when the exponent in any form is required. Moreover, the line 11 is also sloppy-aligned as a consequence of the use of \unit|\high commands because if the line 2a is active, the alignment position is computed properly and the line 11 is ok. Is it a bug, or am I doing something wrong? Best wishes, Tomáš \starttext \setupTABLE[c][2][alignmentcharacter={text->,}, aligncharacter=yes, align={lohi,middle}] \bTABLE \bTR\bTD Line \#1 \eTD \bTD39 \eTD \eTR \bTR\bTD Line \#2 \eTD \bTD 42,185 \eTD \eTR %\bTR\bTD Line \#2a \eTD \bTD 55 550,21 \eTD\eTR \bTR\bTD Line \#3 \eTD \bTD 41,85\,\% \eTD \eTR \bTR\bTD Line \#4 \eTD \bTD 1125,80 centimeter \eTD\eTR \bTR\bTD Line \#5\eTD \bTD 1125,80 \unit{cm} \eTD\eTR \bTR\bTD Line \#6 \eTD \bTD 129,30 \unit{square centimeter} \eTD\eTR \bTR\bTD Line \#6a \eTD \bTD 129,30 \unit{m2} \eTD\eTR \bTR\bTD Line \#7 \eTD \bTD 129,30 \unit{m} \eTD\eTR \bTR\bTD Line \#8 \eTD \bTD 129,30 cm$^{\tfxx2}$\,\eTD\eTR \bTR\bTD Line \#9 \eTD \bTD 0,21 m\high{2} \eTD\eTR \bTR\bTD Line \#10 \eTD \bTD 41,85 \% \eTD\eTR \bTR\bTD Line \#11 \eTD \bTD 55 550,21 \eTD\eTR \bTR\bTD Line \#12 \eTD \bTD 0,21 \eTD\eTR \eTABLE \stoptext

A5 != 210mm x 148mm ?
by Kerry Sainsbury 03 Nov '19

03 Nov '19

Hi, If A5 is 210mm x 148mm (and the internet assures me that it is <https://papersizes.io/a/a5>), then shouldn't these two setuppapersize variants give the same result? They don't *seem* to. %\setuppapersize[A5] \setuppapersize[height=210mm, width=148mm] \starttext \input ward.tex \stoptext The reason I ask is because I'd like to prepare a PDF for printing via IngramSpark, and have discovered that (bizarrely) their Australian branch doesn't support A5 for colour books. They do offer 6x9 (229x152), and I was wondering what values to use in 'setuppapersize', so I thought I'd experiment with the A5 sizing because it's a well known size. Now I have no idea :-( Thanks Kerry

beta
by Hans Hagen 29 Oct '19

29 Oct '19

Hi, I uploaded a beta. In lmtx there is now a bit more advanced support for svg. A preliminary manual is included that explains a few things. As a teaser ... it is also possible to embed svg code, as in: \startbuffer[svgtest] <svg> <circle cx="50" cy="50" r="40" stroke="green" stroke-width="10" stroke-opacity="0.3" fill="red" fill-opacity="0.3" /> <circle cx="150" cy="50" r="40" stroke="green" stroke-width="10" fill="red" opacity="0.3" /> </svg> \stopbuffer \startTEXpage \includesvgbuffer[svgtest] \stopTEXpage \startTEXpage \includesvgbuffer[svgtest][offset=2bp] \stopTEXpage or in metapost disguise: \startMPpage vardef svg expr c = lmt_svg [ code = c ] enddef ; draw svg "<svg> <circle cx='50' cy='50' r='40' stroke='green' stroke-width='10' stroke-opacity='0.3' fill='red' fill-opacity='0.3' /> <circle cx='150' cy='50' r='40' stroke='green' stroke-width='10' fill='red' opacity='0.3' /> </svg>" ; \stopMPpage It is not a replacement for metapost (which is more efficient runtime anbyway) but for artistic images a mixture might work out ok. In principle inclusion with externalfigure also works when conversion=mps is set but, although I have some 1500 test images, not all might work out well. There can be a lot of crap be hidden in svg files and angle brackets are no guarantee for properly structured images. Especially fonts can be troublesome. On the other hand, if one has very structured input, text labels can be swapped for propertly typeset ones (like math), but that's for later to explain (experimental stuff). We'll see.

Luatex 1.08.0 announcement
by luigi scarso 28 Oct '19

28 Oct '19

============================================================== LuaTeX 1.08 2018-08-28 ============================================================== (1) This release is a prelude to 1.10, the next stable iteration of LuaTeX after version 1.00. (2) Lua 5.3 is now considered to be default and we might use 5.4 in version 1.10. There are no real functional changed expected. You still need to rename the binary for 5.3! (3) Binary mode is no longer available in MPlib but it is still available in stand alone MetaPost. This simplifies compilation and reduces dependencies. (4) The dependency on Poppler for pdf image inclusion has been removed. We now use a small dedicated library written by Pawel Jakowski. We no longer need c++ compilers. We're in the process of making it behave well on all platforms. It has been tested on intel platforms. (5) We know that there can be some (alignment) issues with the arm platform but these are looked into. Therefore, later this year we will release 1.09. Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and arm platforms at that point. (6) There have been some extensions to the Lua libraries and some callbacks have been added. Also, a few new primitives have been introduced. The documentation mentions the stable extensions. (7) There are the usual bug fixes and cleanups but there have been no real fundamental changes in the API. The LuaTeX team

luametatex install as root in OpenBSD
by Damien Thiriet 21 Oct '19

21 Oct '19

Hello, When I installed luametatex as root under OpenBSD amd64 this morning, I first had "no permission" to launch context. So I checked my /usr/local/context file (where I unpacked the zip). The symlink context had the right permissions after install process (-rwxr-xr-x root wheel) but not luametatex. I changed permissions for luametatex to -rwxr-xr-x root wheel but maybe it should be introduced at install script level? Btw, context.lua and mtxrun.lua are both installed with permissions -rwxr--r-- root wheel Are those lua script only called by root? Should I change their permissions as well to -rwxr-xr-x? Greetings, Damien Thiriet

Hi again, I’m testing columns again, and before I publish an article on the subject, I’d like to check with you. Find attached my testing environment, env_test.tex, and columns.tex, a "product", as well as the result of compiling with —mode=oldcolumns,grid and —mode=grid The "oldcolumns" example shows the result of \usemodule[old-columns] and looks like it should. The new columns code still has errors: Previously it wasn’t possible to start (new) columns mid-page, i.e. after an image or chapter/intro like in the example. This works now (progress!), but the pre-columns stuff is still shifted to the right. (And I don’t know where the yellow box comes from.) Additionally, footnotes in old-columns use the whole width and don’t interfere with the text columns, while in new columns, footnotes start in their column but use the whole width anyway and thus interfere with the main text. I tried \setupnotes[footnote][location=columns] (and other options) but saw no change. Many more options to check… Best, Hraban

PDF viewer poll
by Henning Hraban Ramm 21 Oct '19

21 Oct '19

Hi, I’d like to update my list of (usable!) PDF viewers. Which one do you use? (Current version?) What are its pros and cons? Is it free (open source, freeware)? Does it work on Win/Lin/Mac? Does it have a localized interface? (I don’t care, but I work with people who don’t understand a lot of English.) Can it handle comments, attachments? Can it handle forms with or without JavaScript? Does it support SyncTeX? (Who uses that anyway?) Does it update changed PDFs on its own (or does it even block overwriting)? Which other features are essential for your choice? E.g. I’m working with: - Preview.app (Mac) Default on MacOS, fast & easy. No JS, bad forms support, updates "sometimes". Usable as a previewer, not as a PDF toolbox. - Adobe Reader DC (Mac) I use it only to check forms or as reference. Unusable GUI. - Acrobat Pro 9 (Mac) Was my workhorse, but works on MacOS Mojave only partly; slow & crash-prone; no updates. Can check PDF/X<4 and convert colors. - PDF Studio Pro (on Mac & Linux) Bought to replace AcroPro9; JS support broken; slow startup; no updates. Can check PDF/X, A, UA and convert colors. Ok with forms, but doesn’t support LiveCycle forms (deprecated, but used by German boards). - Qpdfview (Linux) Fast and easy; reliably updates. - PDF.js (Browser or Atom) Is said to do SyncTeX (never tried). Easy, but slow. Updates. Curious: Hraban

Hi Luigi, Unfortunately I cannot check with an up-to-date mkiv, since I didn't succeed in installing standalone mkiv binaries.

LMTX distorts PDF aspect

Dear list, using the document attached to this message with the following sample gives different outputs: \setuppapersize[A3, landscape] \starttext \externalfigure[fc-first.pdf] \stoptext 1. LuaTeX inserts the document fine. 2. LMTX inserts the document distorting its aspect. I’m afraid this might be a bug in LMTX. Could anyone confirm the issue? BTW, the PDF document is uncompressed (so it’s easier to analyze it). Many thanks for your help, Pablo -- http://www.ousia.tk

LTMX install on OpenBSD amd65 working
by Damien Thiriet 19 Oct '19

19 Oct '19

Hello, I am very pleased to inform that I was able to install luametatex on OpenBSD amd64 6.5. I fetched the install file on PRAGMA, followed the instructions and was able to compile a basic file with ltmx. I was also able to compile simple files for my pupils. Unfortunately, compilation fails with more complex files (presentations), I’ll describe this on another mail. Anyway, this is great, because OpenBSD 6.6 (released two days ago) ships texlive 2018, and having the \startxcolumn working will be really helpfull when designing key to symbols for my maps. I'm now looking forward for the OpenBSD 6.6 ltmx binaries. Thanks for all this great job, Damien Thiriet

lmtx and Asana Math
by Otared Kavian 17 Oct '19

17 Oct '19

Hi Hans, Today I noticed that the OT font Asana math was absent from my installation of lmtx, that is from /context-osx-64/tex/texmf/fonts/opentype/public and that was the reason I kept obtaining in my documents different script fonts from the ones I have with mkiv. I copied the font into /context-osx-64/tex/texmf/fonts/opentype/public/Asana-Math and after erasing the cache and making the formats, everything works as expected now. So my question is: can this font be included in the distribution of lmtx so that one doesn't need to manually add it? Or should one install it somewhere else on one's machine? Thank you for everything, Best regards: Otared

Where is tex/texmf-context?
by Henri Menke 16 Oct '19

16 Oct '19

Dear list, Today I wanted to use ConTeXt MkIV instead of LMTX but when I ran context, I obtained the error mtxrun | unknown script 'context.lua' or 'mtx-context.lua' so I went to the installation directory /opt/context to check and noticed that tex/textmf-context was missing. I thought that obviously something must have went wrong with the last update, so I deleted the whole tree and ran the first-setup.sh again using sh ./first-setup.sh --context=latest --engine=luatex --modules=all --fonts=all but tex/texmf-context is still missing. Is any of the options I'm using for the install script broken? Cheers, Henri

how to do adaptation
by Susanne G. Loeber 14 Oct '19

14 Oct '19

Hi, I am looking for ways to adapt the layout and content of texts while using ConTeXt. Put simple: show part of a text and sort these parts based on data from the user and the author (.dat file). The biggest problem is not knowing which part of the text will be first and how many parts will be shown. So far, I am trying to get a hang of \setupdocument (https://wiki.contextgarden.net/Project_structure) \startmode (https://wiki.contextgarden.net/Modes) \definecolor (https://wiki.contextgarden.net/Color) and \defineparagraphs (https://wiki.contextgarden.net/Command/defineparagraphs) I hope there are more ways to create adaptation. I would also like to know whether certain combination don't work together. For example, I cannot seem to get \doifmodeelse to work inside a \defineparagraphs environment. \defineparagraphs[BLpar][n=2, frame=on] \setupparagraphs [BLpar][1][width=\dimexpr.3\textwidth] \starttext % Working \enablemode[asg] \doifmodeelse{asg} {\par First sentence} {\par Second sentence} \disablemode[asg] \doifmodeelse{asg} {\par First sentence} {\par Second sentence} \doifnotmode{asg} {\par Third sentence} % Not working \enablemode[one] \startBLpar \doifmodeelse{one} {First sentence} {Second sentence} \disablemode[one] \BLpar % \disablemode[one] %% not helping TOP1 paragraphs \stopBLpar % \disablemode[one] %% needed to make the example work \startBLpar \doifmodeelse{one} {First sentence} {Second sentence} \BLpar TOP2 paragraphs \stopBLpar \startBLpar \doifnotmode{one} {Third sentence} \BLpar TOP3 paragraphs \stopBLpar \stoptext Kind regards, Susanne G.

Sectionwise page range in ConTeXt TOC
by Jairo A. del Rio 12 Oct '19

12 Oct '19

I know ConTeXt TOC is quite customizable. However, I don't figure out how to include a page range next to section labels. For instance, something like that: 1. Chapter . . . 1 - 4 1.1 Section . . . 1 - 3 1.2 Section . . . 3 - 4 2. Chapter . . . 4 - 7 I've seen a LaTeX implementation here: https://tex.stackexchange.com/a/145206 Is something similar (or maybe better) possible? Thanks in advance.

Re: [NTG-context] new (lmtx) beta

Dear Hans, I read the manual of luametafun and do some examples. Thanks for many new features. It is really great. I’d like to ask two things. 1. On page 26,27, in the manual, > > http://www.pragma-ade.com/general/manuals/luametafun.pdf <http://www.pragma-ade.com/general/manuals/luametafun.pdf> a function name of the graphics are appeared as same as in the argument ‘function = “x^2 + y^2”’. Though it calculates function using “x^2 + y^2”, it is better to write the name of it as the output of $x^2 + y^2$. Is it possible to write it as in mathematical form? 2. To define a mathematical function, it uses “function = “ in Contour, while it uses “code = “ in Surfaces and in Functions. Is there any reason to use two different names “function” and “code” to define functions? Thank you again. Best regards, Dalyoung

List of Symbols/Abbreviations/Glosses with more then two entries
by Thomas Welter 11 Oct '19

11 Oct '19

The synonym "sym" defined by \definesynonyms[sym][syms][\symdesc] can take 2 entries by default: \sym[<RefName>]{<ShortName>}{<LongName>} For theses and whitepapers in the natural sciences and in engineering it is needed to introduce another entry for the unit: \sym[<RefName>]{<ShortName>}{<Unit>}{<LongName>} (<-- This does of course not compile, take it as a feature request) e.g. \sym[Salpha]{\alpha\ }{$[W~m^{-2}~K^{-1}]$}{Heat Transfer Coefficient} where \sym[Salpha]{\alpha\ }{$[W~m^{-2}~K^{-1}]$ Heat Transfer Coefficient} cannot be a good workaround since \symdesc{Salpha} should not include the unit. And of course I want the unit entry to be in a separate column when calling \placelistofsynonyms[sym] In LaTeX I accomplished this with glossaries and glossary-mcols. Is there some neat trick to get this behaviour "the ConTeXt way" (maybe with some Lua + *.aux)? The next step would be to define the table headers of the list of symbols such as "Symbol \NC Unit \NC Description"... Thanks in advance and kind regards, Thomas

new beta
by Hans Hagen 11 Oct '19

11 Oct '19

Hi, I uploaded a new beta. Some might have noticed that stepwise some font support has been redone. We're talking of lmtx only here. For instance low level handling of color fonts as used for emoji but there are also other (often incomplete) fonts out there (overlay, png, svg) has become (on the average) a bit more efficient. It's somewhat tricky to satisfy viewers but at my end things work ok. It should also work in a cmyk only mode. As usual it's work in progress (and in this case very likely lmtx only). Also some first (runtime) metafun (2) font creation support has been added (was always possible but it's a bit more convenient now). An example can be found in: meta-imp-gamesymbols.mkxl (the file can be processed with the 'context' command and will produce an example). As usual imagination determines the limits of what context provides, so feel free to suggest more (examples). Again this is lmtx specific.

Documentation of change / Evolving documents
by Axel Kielhorn 11 Oct '19

11 Oct '19

Hi, I often have documents that are not finished but need to change over time. A client changes their mind, laws are changed, … While working with the document, I want to see the changes. When the document is finally finished, I only want to see the change history. I came up with the following. When the mode is „change“ the date (or version) is shown in the margin and the change is printed in red. Without mode „change“ only the change history is printed. What I want now is to change the layout of the register. Adding some vspace around the date and printing the date in bold. Is there a way to achieve this or am I on the wrong way? (Should the date be the indicator, thus giving me the layout I want?) \enablemode[change] \setuppapersize [A4][A4] \setuplayout [width=middle, backspace=1.5in, cutspace=1.5in, height=middle, topspace=0.75in, bottomspace=0.75in] \setupbodyfont[11pt] \defineregister [change] \setupregister [change] [ indicator=no %% no letter style=sansbold, %% headings textstyle=slanted, %% entries pagestyle=bolditalic, %% page refs n=1, %% columns ] \def\ChangeV#1#2{\change{#1+#2}\doifmode{change}{\inmargin{\tx #1}{\red #2\par}}} \def\ChangeD#1#2{\change{#1+#2}\doifmode{change}{\inmargin{\tx #1}{\red #2\par}}} \starttext \ChangeV{V. 1.0}{Fertig!} \input knuth \ChangeD{2018-12-22}{Fertig!} \ChangeD{2018-12-23}{Letzter Fehler beseitigt.} \input knuth \ChangeD{2018-12-23}{Allerletzter Fehler beseitigt.} Ende \startsection[title={History}] \placechange \stopsection \stoptext

Hi Mojca, Hi Robert I tried to install standalone according to your instructions, but I failed one more time. I did the following steps: mkdir context && cd context rsync -ptv rsync://contextgarden.net/standalone/setup/first-setup.sh . ./first-setup.sh Then I changed the line 4049 of bin/mtxrun to local platform="openbsd6.5-amd64" but I obviously did not understand what to do next: calling env PATH="$PWD/bin:$CONTEXTROOT/texmf-$platform/bin:$PATH" MTX_PLATFORM="$platform" \ ./bin/mtxrun --script ./bin/mtx-update.lua --force --update --make --engine=luatex --platform="$platform" --texroot="$CONTEXTROOT" $@ ends quite quickly, with this output mtx-update | available platforms: freebsd freebsd-amd64 linux linux-64 linux-armhf linuxmusl-64 mswin openbsd6.5 openbsd6.5-amd64 osx-64 solaris-intel solaris-sparc win64 resolvers | tds | no 'texmf-openbsd6.5-6.4' under tree '/home/<name>/context/' which is the same output as ./first-setup.sh before the change. (changed my home name to <name>) What did I do wrong? Greetings, Damien Thiriet

Dear list, I have the following sample: \setupinteraction[state=start, focus=standard] \starttext a\footnote{b} \stoptext Using latest beta from MkXL (2019.10.05 14:56), link form footnote to main text body doesn’t work. Latest beta from MkIV (2019.10.05 14:45) has no issue and the footnote link works perfectly fine. Could anyone confirm this issue with links in footnotes for LMTX? Many thanks for your help, Pablo -- http://www.ousia.tk

passing variables/data between context and lua
by Martin Althoff 08 Oct '19

08 Oct '19

Hi, I am trying to pass variables/data between context and lua. Lua would be used for calculations on data coming from context. Unfortunately I can't figure out what to do. The code below doesn't work, but is there to illustrate my idea. Any help would be much appreciated. Thanks, Martin \define\question{44} \starttext \startluacode local points = \question * 92 -- do some calculations with points and return to to context answer=42 \stopluacode % lots of Text in between The answer is \answer \stoptext

issue with JavaScript in Acrobat
by Pablo Rodriguez 08 Oct '19

08 Oct '19

Dear list, I have this minimal sample: \setupinteraction[state=start] \setupinteractionscreen[option=max] \startJSpreamble {varia} used now var transitions = [1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000]; var msecs = 0; function step_clock() { try { ++msecs ; if ((msecs >= (transitions[this.pageNum]/10)) && ( this.pageNum < this.numPages )) { ++this.pageNum; }; } catch (e) {} } advance = app.setInterval ("step_clock()", 1); advance.count = 0; \stopJSpreamble \starttext \dorecurse{10}{\startTEXpage[pagestate=start, offset=1em] \pagenumber \stopTEXpage} \stoptext Acrobat is required. And I have an issue with it Each slide takes a full second (1000 milliseconds). But the conditional in step_clock() needs to divide the elements from transitions array by ten. Otherwise it is ten times slower. Am I missing something here? Or why is "step_clock()" ten times slower than it should be? Many thanks for your help, Pablo -- http://www.ousia.tk

Printing catchword or kustode
by Jan Ulrich Hasecke 08 Oct '19

08 Oct '19

Hi all, Visiting a museum in Straßburg I saw an old book from Gutenbergs times where the first word of the next page was printed below the last line of the current page. The word, sometimes only a syllable of the first word from the next page, is called catchword or Kustode. They used it to ensure that they bind the pages in the right order. I think that it can also be of help if you read a book. Is this possible with ConTeXt? I could not find the word catchword, reclamans or kustode on the wiki.

changing an XML node and reprocess it (or xmlflushing a string)
by mf 08 Oct '19

08 Oct '19

Hello, i'm using XML and i find useful specifying a fraction made of text this way: <span class="fraction">text for numerator/text for denominator</span> With some lua, i can transform it into \frac{\text{text for numerator}}{\text{text for denominator}} which typesets something like this: text for numerator -------------------- text for denominator Suppose you want to add some styling to the texts, like this: <span class="fraction">text for <i>numerator</i>/text for <b>denominator</b></span> You should split the span node into two elements and the xmlflush them. This is my M(not)WE: \startbuffer[text] <p>A paragraph with a fraction made of text with styles: <span class="fraction">a <i>fraction</i> made of text/with <red>styles</red> inside</span>.</p> \stopbuffer \startluacode local sub = string.sub local sfind = string.find local xmltext = xml.text local xmlconvert = xml.convert local function numeratorDenominator( text ) local before, after = sfind( text, "[^<]/[^>]" ) local num, den if before and after then num = sub( text, 1, before ) den = sub( text, after ) end return num, den end function xml.functions.textfraction( t ) local text = xmltext( t, '' ) local num, den = numeratorDenominator( text ) if num and den then local fontstyle = tokens.getters.macro( "fontstyle" ) local xml_num = xmlconvert( num ) local xml_den = xmlconvert( den ) -- context( "$\\frac{\\text{\\" ..fontstyle .. " " .. num .. "}}{\\text{\\" ..fontstyle .. " " .. den .. "}}$" ) context( "$\\frac{\\text{\\" ..fontstyle ..

Below is a much shorter version of your example to demonstrate the problem. The problem is a check in the section command which fails when the character comes from a fallback font.

Hi all, I may be missing something really obvious: is it possible to change the shape of single connection lines in the flowchart module?
