new upload
by Hans Hagen 01 Dec '20

01 Dec '20

Hi, I uploaded a new version. This time some cleanup of the backend, so let's see where I messed up this time. The installer has been adapted so that an apple m1 machine is recognized. No native arm bins, that has to wait till we have some hardware available.

Install Problems with 64 bit ARM Linux
by Christian Prim 01 Dec '20

01 Dec '20

Hi everyone Is there a reason why the arm binaries for ARM Linux use version 2.29 of glibc? My actual debian buster installation is still on glibc-2.28. The x86_64 Linux binaries also use the older 2.28-version which is widely used among many distros. I would be very happy if I could install a 2.28-version on my ARM Linux box. Else I have to compile my own glic... or my own mtxrun... Many thanks for your clarifications Christian PS.: error messages during the install: .../lmtx/bin/mtxrun: /lib/aarch64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by .../lmtx/bin/mtxrun)

install.sh not working on Linux (Ubuntu 20.04)?
by Jairo A. del Rio 01 Dec '20

01 Dec '20

Hi everybody. Is anyone else having problems with recent ConTeXt updates on Linux? Since last month, install.sh isn't doing anything. However, when I go to Pragma ADE's website, I can download newer releases and they work fine (e.g. --permitloadlib works now). I'm not so picky about manual downloads, but I think install.sh is (or was) quite better. I'm on Ubuntu 20.04, in case it helps. Thank you very much. Regards, Jairo :)

Adding syntax highlighting when typesetting from xml (asciidoc/docbook)
by Mojca Miklavec 01 Dec '20

01 Dec '20

Hi, A while ago Hans provided an example of typesetting a document from a docbook source. I'm attaching an over-simplified version of the initial module (a somewhat more complete version exists, but it still needs lots of work) and a minimum working example with XML. I'm not sure how to extend the xml parser to support typesetting from something like this: <section xml:id="_hello_world_in_c_and_context"> <title>Hello World in C and ConTeXt</title> <programlisting language="cpp" linenumbering="unnumbered">#include <stdio.h> int main() { printf("Hello, World!\n"); return 0; }</programlisting> <programlisting language="context" linenumbering="numbered">\starttext Hello world! \stoptext</programlisting> </section> Maybe using the vim module would be the right approach here (since the built-in parser only has support for a limited set of languages), but I'm not exactly sure about the implementation to achieve that goal. I started with \startxmlsetups xml:programlisting \dontleavehmode \startframedtext[background=color,backgroundcolor=lightgray] \obeylines \tt \xmlflush{#1} \stopframedtext \stopxmlsetups but something more is needed to properly handle new lines and to properly pass the text to vim, for example. Any hints welcome. Thank you, Mojca

Bug in lmtx bibliography (numerals in entry?)

Hello, My bibliography files compiles fine in mkiv, but hangs in lmtx Here is the error message: tex error > tex error on line 30 in file ./Nation_rev_empire.mkiv: Use of \btxshowentryinline doesn't match its definition <macro> \btxflushlisttext ...tyleandcolor \c!style \c!color \ignorespaces \publ_fast_setup \plusfour \s!list \currentbtxcategory \removeunwantedspaces \endgroup <argument> \btxflushlisttext \ifx \currentbtxcombis \empty \else \btxrenderingparameter \c!separator \btxflushlistcombis \fi <macro> \btx:list:inject:text ...al \btxinteractivetext \ifx \currentbtxinternal \empty #1\else \goto {#1} [\s!internal (\currentbtxinternal )]\fi \else #1 \fi <macro> \btx_entry_inject ...onal \c_btx_list_texts \dostarttagged \t!listtext \s!left \currentbtxbefore \dostoptagged \fi \btx_entry_inject_list_text \ifconditional \c_btx_list_pages \dostarttagged \t!listpage \empty \btx_entry_inject_pages \dostoptagged \fi \ifconditiona... <macro> \currentlistentrytitle \dostarttagged \t!listcontent \empty \btx_list_reference_inject \btx_entry_inject \dostoptagged <macro> \22>:139>:paragraph ...\relax \fi \fi \fi \begingroup \useliststyleandcolor \c!textstyle \c!textcolor \setstrut \begstrut \currentlistentrytitle \endstrut \endgroup \ifconditional \c_lists_has_page \ifconditional \c_lists_show_page \nobreak \currentlistfiller \beging... […] If you say, e.g., '\def\a1{...}', then you must always put '1' after '\a', since control sequence names are made up of letters only. The macro here has not been followed by the required stuff, so I'm ignoring it. I am using a custom biblio style, but the command \btxshowentryinline is not directly called inside. My ConTeXt version mtx-context | ConTeXt Process Management 1.04 mtx-context | mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.11.19 11:28 mtx-context | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.11.19 11:28 AFAIU, it means my entry shouldn’t have numbers, right? If so, this may be a bug, since entry biblio files often have a number inside Best regards, Damien Thiriet

Combinations not working as expected
by Christoph Reller 01 Dec '20

01 Dec '20

Dear list, In the latest version 2020.11.28 13:18 of ConTeXt LMTX, combinations don't seem to work as expected. Example: \starttext \startcombination[2*1] {first}{a} {second}{b} \stopcombination \blank[big] \startcombination[1*2] {first}{a} {second}{b} \stopcombination \stoptext The output is [image: image.png] The layout argument [2*1] or [1*2] does not seem to have an effect and the caption placement for "b" is strange. Am I doing something wrong? Cheers, Christoph

framedtext is (still) broken in LMTX
by Rik Kabel 30 Nov '20

30 Nov '20

With ConTeXt ver: 2020.11.28 13:18 LMTX fmt: 2020.11.29 the *\framedtext* output is consistently *0.8\textwidth*. MkiV gives the expected result. \starttext \framedtext{Fail}\par \framedtext[width=fit]{Fail}\par \framedtext[width=3cm]{Fail}\par \framedtext[width=0.8\textwidth]{Fine by accident}\par \framedtext[width=\textwidth]{Fail}\par \framed{Fine}\par \framed[width=fit]{Fine}\par \framed[width=3cm]{Fine}\par \framed[width=0.8\textwidth]{Fine}\par \framed[width=\textwidth]{Fine}\par \stoptext -- Rik

Problem with word not hyphenating
by Bruce Horrocks 30 Nov '20

30 Nov '20

The word "re-implementation" refuses to hyphenate and consequently stick outs into the right margin. I've tried using \hyphenation but it makes no difference. \showframe \starttext \hyphenation{re-im-ple-men-ta-tion} Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod re-implementation tempor incididunt ut labore et doloremagna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. \stoptext Any suggestions, please?

Using ConTeXt-LMTX for modern Mathematically-Literate-Programming 2/2
by Stephen Gaito 30 Nov '20

30 Nov '20

Hello (again), This email is further to my previous "Using ConTeXt-LMTX for modern Mathematically-Literate-Programming 1/2" email... My ultimate goal in using ConTeXt-LMTX as a Mathematically-Literate-Programming tool, is to actually write a kernel "Mathematical Language" in ANSI-C (wrapped in Lua) which is then imported back into ConTeXt-LMTX as a standard Lua module (with an ANSI-C shared library). This would allow the output of "code" in my "Mathematical Language" to be directly embedded/typeset in the output of my Mathematical document. (The ultimate goal is to ensure that there is NO wishful thinking that the code is "correct" ("just trust me")... all results would be directly visible in the PDF). Alas, while, for other reasons, trying to use the Lua-CJSON Lua module from within ConTeXt-LMTX (which also makes use of a shared library written in C), I find that the current ConTeXt-LMTX is missing (among potentially others) the `lua_checkstack` symbol: > ...Xt/tex/texmf-context/tex/context/base/mkiv/l-package.lua:333: error > loading module 'cjson' from file '/usr/local/lib/lua/5.4/cjson.so': > /usr/local/lib/lua/5.4/cjson.so: undefined symbol: lua_checkstack even when using the ConTeXt/LuaMetaTeX `--permiteloadlib` switch. (Note that this Lua-CJSON module does work with the native 5.4 Lua). (The ConTeXt I am using identifies itself as: ConTeXt ver: 2020.11.25 19:18 LMTX fmt: 2020.11.25 int: english/english) I note that the output of `luametatex --help` includes the following statement: > Loading libraries is blocked unless one explicitly permits it (will > be in 2.08+): > > --permitloadlib permit loading of external libraries (coming) ---- QUESTIONS: 1. Is this an oversight and `--permitloadlib` is meant to be working now? 2. Is this a trivial fix (and might be fixed soon -- time permitting)? 3. Is this a rather complex refactoring of the code/build system (and hence might take some time before a fix can be rolled out)? 4. Is this a case of "the `lua_checkstack` symbol will never be part of luametatex"? ---- Any of the above scenarios is OK (though scenario 4 would be a disappointment as it means no shared library lua modules could be used in ConTeXt)... ... it would however be useful to have an idea of which scenario is most likely. Again Many thanks for a wonderful (and stable) tool! Regards, Stephen Gaito

mathmatrix and internal lines
by Jean-Philippe Rey 30 Nov '20

30 Nov '20

Dear list, I would like to draw matrices with internal lines as can be done with LaTeX (cf pdf output) : ======================== \documentclass{article} \begin{document} $M =\left( \begin{array}{c|c} A & B \\ \hline C & D \\ \end{array} \right)$ \end{document} ======================== I didn't find out how to use mathmatrix to achieve this. My best result to date is ======================== \starttext $M = \left( \bTABLE[frame=off] \bTR \bTD[rightframe=on, bottomframe=on] $A$ \eTD \bTD[bottomframe=on] $B$ \eTD \eTR\bTR \bTD[rightframe=on] $C$ \eTD \bTD $D$ \eTD \eTR \eTABLE \right)$ \stoptext ======================== The code is rather ugly, and I get a spurious space at the bottom of the table. Any hints? Thank you, -- Jean-Philippe Rey jean-philippe.rey(a)centralesupelec.fr 91192 Gif-sur-Yvette Cedex - France Empreinte PGP : 807A 5B2C 69E4 D4B5 783A 428A 1B5E E83E 261B BF51
