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}

Dear list, after latest from 2020.09.20, I afraid I get this error when running install.sh on Linux or install.bat on Windows (both 64bit): mtx-install | updating tex/texmf, 1541 files mtx-install | updating tex/texmf-context, 3757 files mtx-install | changed : 0 % : 24110 : tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua mtx-install | tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua, trying again: mtx-install | changed : 0 % : 24110 : tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua mtx-install | tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua, trying again: mtx-install | changed : 0 % : 24110 : tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua mtx-install | tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua, trying again: mtx-install | changed : 0 % : 24110 : tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua mtx-install | tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua, trying again: mtx-install | changed : 0 % : 24110 : tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua mtx-install | tex/texmf-context/context/data/scite/context/lexers/data/scite-context-data-context.lua, try again later: If you want to run ConTeXt everywhere, you need to adapt the path, like: I don’t know what has changed to prevent the update. Could anyone confirm this issue with current LMTX? Many thanks for your help, Pablo -- http://www.ousia.tk

Is there any intuitive way of handling missing characters?
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, Is there any way to give a sequence of fonts to context and let it try one after another in case of missing characters? Ideally it should be something like \usefallback[font1,font2,font3,...] The methods I've found are all way too complicated for someone who does not really care about fine-grained control over unicode coverage or customizing a typeface with different serif/sans/math/... combinations from different typefaces. Thanks! Best, Sylvain

How does lua callback work?
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, I'm trying to intervene whenever context encounters a character that it cannot render in the current font. I guess this should have something to do with lua callbacks (pls correct me if I'm wrong), but the document <http://www.pragma-ade.nl/general/manuals/cld-mkiv.pdf> does not seem to elaborate on this. Does anyone know how the aforementioned task can be done, or how lua callbacks work in terms of the meaning of the concerned events and parameters? Thanks! Best, Sylvain

How to draw a horizontal line of 0.5\paperwidth ?
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, I've tried \hl[0.5\paperwidth] but context complains 'a number should have been here' since \hl assumes 'em' as unit. Does anyone know how to draw a horizontal line of 0.5\paperwidth ? Thanks! Best, Sylvain

context.delayed as parameter of setuphead[before=...]
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, I'm trying to mirror the context command `\setuphead[chapter][before=hello]` into lua with delayed typesetting of 'hello', but `\ctxlua{context.setuphead({'chapter'}, {before=context.delayed'hello'})}` does not have any effect. Could anyone help me on this? Thanks! Best, Sylvain

How to really set the paper margin?
by Sylvain Hubert 04 Nov '20

04 Nov '20

Dear List, The following example results in a pdf that has a wide margin on both sides despite the \setuplayout : \showframe \setuppapersize[A4][A4] \setuplayout[margin=0cm, edge=0cm, margindistance=0cm, edgedistance=0cm] \starttext hello world \stoptext Does anyone know how to really set the paper margin? Thanks! Best, Sylvain

caching remote images
by Jano Kula 04 Nov '20

04 Nov '20

Hello! I'd like to cache images (order of hundreds) from a remote location (not all the time mapped as drive, download speed and amount of data are also the factors). \usepath[dirfile://./resources/**] is likely for speeding up searching not downloading and I don't know when new images are available (when to delete dirlist.* files), as described in workflows-mkiv.pdf. Looks like the cache parameter in \externalfigure is used only if some conversion is going on. I could create a conversion which does nothing or only envelopes JPG in PDF as <id>.jpg.pdf (loading could be faster) and then: if cached file exists use cached <id>.jpg.pdf else if drive is mapped download, convert and cache <id>.jpg else skip file end end The source file with one <id> will never change or I could re-cache from time to time to have up-to-date images cached. Before reinventing the wheel: isn't such functionality or part of it already available? Thanks, Jano

Adding built-in support for Serbian language
by Ivan Pešić 03 Nov '20

03 Nov '20

Hello all, I have recently started using ConTeXt. I've found that the distribution includes a proper (cyrillic) hyphenation file for Serbian language, but a complete language support is still not implemented. Therefore, I've added what I think is required, did some testing by putting changed files in my texmf-local, and the result looks fine. There is only one thing that requires a decision from the development team. Serbian language uses two scripts: cyrillic and latin. Context language codes are using 2 letters for identification. So I'm not sure how to include both scripts. What I'm sending now is a cyrillic script implementation, using the code "sr". It is trivial to generate (completely automatic) latin script version of these changes, once it is decided how to label it. Best regards, Ivan
