specify column-width, with option=stretch
by Peter Münster 06 Nov '20

06 Nov '20

Hi, I would like to specify the column-width of the first column to 5mm: --8<---------------cut here---------------start------------->8--- \starttext \setupTABLE[textwidth=99mm, option=stretch] \setupTABLE[c][each][align={lohi, middle}] \setupTABLE[c][1][height=5mm, style=\tfxx] \framed[width=5mm, offset=0pt]{5} \bTABLE \bTR \bTD[nr=2] \setupinterlinespace[1.8ex] 1\\2\\3 \eTD \bTD bla \eTD \bTD blablabla \eTD \eTR \bTR \bTD[nc=2] blabla \eTD \eTR \eTABLE\par \framed[width=99mm, offset=0pt]{99} \stoptext --8<---------------cut here---------------end--------------->8--- How could I do that please? TIA for any hints, -- Peter

Why is the textarea not centered by default?
by Sylvain Hubert 05 Nov '20

05 Nov '20

Dear List, \starttext \showframe \showsetups \stoptext This minimal example without further configuration shows that the default value for backspace, textwidth and paperwidth are 2.5cm, 15cm, 21cm resp., which means that the textarea is horizontally 0.5cm off the center by default, and one can indeed see a clear extra margin on the right side. This seems weird but I'm no expert of typesetting, so does anyone know why it has been set like that? Thanks. Best, Sylvain

ConTeXt Standalone last version
by Joaquín Ataz López 05 Nov '20

05 Nov '20

The last time I checked the date of the ConTeXt Standalone version I had installed was early last summer, and the version installed was April 30, 2020. But today I wanted to update the version and I see that the "new" version that has been installed is the version of January 30, 2020. That is: the version has been moved back. Does anyone know why it has regressed? -- ------------------------------------- Joaquín Ataz López Profesor de Derecho Civil Universidad de Murcia - Departamento de Derecho civil

What is "cutspace" and "bottomspace"?
by Sylvain Hubert 05 Nov '20

05 Nov '20

Dear List, according to https://wiki.contextgarden.net/Command/setuplayout , "cutspace" and "bottomspace" are the counterparts of "backspace" and "topspace", and "If cutspace is set to 0, it is taken to be equal to the backspace". But in fact, the following document stays the same no matter what value is given to cutspace. \setuplayout[cutspace=0.01cm] \starttext x \showframe \stoptext Has anyone actually used these two parameters? Best, Sylvain

MP background for text typeset by \typefile
by context＠vivaldi.net 05 Nov '20

05 Nov '20

Hello, is there a way to draw custom background (via MP) to a text typed by \typefile, which is so long so it spreads over more pages? - I'm asking because I know how to typeset some text via \typefile with: 1. this: \definetyping[Test] [before={\startbackground[background=color,backgroundcolor=blue] }, after={\stopbackground }, ] - which creates a rectangular backround to the text, and the text may spread over pages; 2. or this: \defineoverlay[AnOverlayDefinition][] \definetyping[Test] [before={\startframedtext[background=AnOverlayDefinition, ]% }, after={\stopframedtext }, ] - which allows to define a custom background via overlay/MP, but which encloses the text to be typeset into a framed, and thus doesn't spread over pages. My intention is to "decore" the text typed by \typefile with a "fuzzy" background, which uses overlay/MP. But I am in the sitaution where I am able to figure out MP code just when the text is to be enclosed into \framed. Is it possible to combine both cases? How? Best regards, Lukas

\blank[] doesn't work when nothing precedes it
by Sylvain Hubert 05 Nov '20

05 Nov '20

Dear List, I'm trying to put the document title at around .25\paperheight by inserting a \blank: \setuplayout[topspace=0cm, header=0cm, height=\paperheight] \starttext \blank[.25\paperheight] foo \stoptext But the "foo" still appears at the very top. Does anyone know why it behaves like that, or whether there is a more authentic way to put the first word at .25\paperwidth than inserting a tiny invisible space before the \blank? Thanks! Best, Sylvain

Bug: context/mtxrun makes Firefox eat up cpu
by Sylvain Hubert 05 Nov '20

05 Nov '20

Hi, sorry if this is not the best place to file a bug but I found no working bug tracker for context. Environment: Manjaro 20.1.2, context 2020.09.20 23:02, firefox 82.0 Step to reproduce: 1. `firefox --safe-mode # start firefox without add-ons` 2.a`context --version # or --help, or without arguments` 2.b or: `mtxrun --script font --list --all` Expected behavior: Nothing surprising should happen. Actual behavior: Firefox suddenly eats 100% of cpu I've noticed that `context` symlinks to `luametatex`, but the latter itself does not trigger the bug, neither do `luatex` or `latex`, so I believe this is a context-specific thing. Best, Sylvain

About loading C libraries (again)
by Jairo A. del Rio 05 Nov '20

05 Nov '20

Hi. I've just read in the LuaMetaTeX manual that --permitloadlib allows loading compiled (.so/.dll) libraries. However, when I try it using ConTeXt I have an error message (example below): %hello.tex \starttext \startluacode local hello = require"hellolib" -- hellolib.so context(hello.helloworld()) \stopluacode \stoptext %hello.c #include <lua.h> #include <lauxlib.h> static int helloworld (lua_State *L) { char hello[] = "Hello world!"; lua_pushstring(L, hello); return 1; } static const struct luaL_Reg hellolib [] = { {"helloworld", helloworld}, {NULL, NULL} }; int luaopen_hellolib (lua_State *L){ luaL_newlib(L, hellolib); return 1; } error (lua loadlib): you can only load external libraries when --permitloadlib is given On the other hand, manually calling LuaMetaTeX with the ConTeXt format and --permitloadlib gives the expected result (in this case, a "Hello world!"). How is the correct way to load those libraries? Thank you very much and sorry if my question seems to be weird. Best regards, Jairo :)

What does --errors and --noconsole do?
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, I was reading workflow-mkiv <http://www.pragma-ade.nl/general/manuals/workflows-mkiv.pdf> and have found the '--errors' and '--noconsole' arguments which seemed quite helpful since, according to the documentation, "show errors at the end of a run" and "disables logging to the console" while "error reporting mentioned in the previous section will never be silenced". But when I run 'context --errors' for the following document \setuppagenumbering[footer] \starttext hi \stoptext the message setup > error in line 1, namespace 'pagenumbering', key 'footer,' still lies in the middle of a bunch of messages and is not shown in the end. When I add '--noconsole' to the arguments, the error disappears along with all the other messages. So is there any combination of arguments that can let context only display what matters to the user? Thanks in advance. Best, Syiain

French spacing in ConTeXt
by Tomas Hala 04 Nov '20

04 Nov '20

Hi all, the following code works for the default roman family but not for tt-family. \setuplayout[width=30cc,height=70cc,topspace=0cc] \def\sample{\input knuth \par\thinrule\par} \starttext \setuplanguage[en][spacing=packed] \mainlanguage[en] \sample \setuplanguage[en][spacing=broad] \mainlanguage[en] \sample \tt \setuplanguage[en][spacing=packed] \mainlanguage[en] \sample \setuplanguage[en][spacing=broad] \mainlanguage[en] \sample \stoptext As far as I know, the broad spacing (=non-frenchspacing) should work also for typewriter. How could I enable it? Best wishes, Tomáš P. S. LaTeX code (only for comparison) works for both: \documentclass{article} \begin{document} \frenchspacing \input knuth \nonfrenchspacing \input knuth \tt \frenchspacing \input knuth \nonfrenchspacing \input knuth \end{document}
