Replacing %20 with spaces in xml attributes
by denis.maier＠unibe.ch 21 Jul '23

21 Jul '23

Hi, I'm typesetting an XML document where the links to the images contain spaces which are encoded as %20 <graphic xlink:href="a%20filename%20with%20spaces.jpg"/> Using this works in cases without spaces: \startxmlsetups xml:fig:graphic \externalfigure[\xmlatt{#1}{xlink:href}] \stopxmlsetups This also works for normal spaces, but is there a way to decode/expand the %20s to regular spaces? I've tried with some Lua, but I don't really know how to pass data around. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startluacode function replaceSpaces(s) result = string.gsub(s, "%%20", " ") context(result) end \stopluacode \define[1]\replaceSpaces{\ctxlua{replaceSpaces("#1")}} \startxmlsetups xml:fig:graphic \externalfigure[\replaceSpaces{\xmlatt{#1}{xlink:href}}] \stopxmlsetups %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Any hints, why this does not work?` Also, maybe there's a simpler way for this kind of scenario? Best, Denis

OSFONTDIR
by Thomas A. Schmitz 21 Jul '23

21 Jul '23

Hi everybody, just a short question: I was under the impression that ConTeXt would not look for system fonts unless we set OSFONTDIR explicitly; this appears to be the basis of the page Use_the_fonts_you_want on the wiki, and I prefer this behavior because it lets me control the fonts I want to use. Recently, however (when exactly? I don't know.) this seems to have changed, and ConTeXt now searches the system font directories by default. I found this out because one of my documents is set up to use the STIX2 fonts. In the most recent versions of macos, some files of these fonts are included as system fonts under /System/Library/Fonts/Supplemental, but not all of them. It took me some head scratching to figure out why every run complained about missing glyphs until I saw that ConTeXt was using the wrong font. I had to set the variable OSFONTDIR to some value to prevent this from happening. So my question is: is looking for system fonts by default the new standard? Is it a good idea? Thank you and all best Thomas

Problem with latest
by Thomas A. Schmitz 20 Jul '23

20 Jul '23

Hi everybody, The latest (2023.07.18 22:07) has a consistent problem with all files on my computer; every run has this: fatal lua error: registered function call [1715]: ...s/lmtx/tex/texmf-context/tex/context/base/mkxl/l-lua.lmt:84: attempt to call a nil value (upvalue 'popen’) Does anyone else see this as well? All best Thomas

Suppress label in captions without suppressing number
by denis.maier＠unibe.ch 20 Jul '23

20 Jul '23

Hi, is there an option to suppress the label in captions without suppressing the number as well? I know, I can use \setuplabeltext[de][figure=,], but this will delete the label text globally... Is there a better way via \setupcaption? Best, Denis

Custom highlight ConTeXt syntax in AUCTEX
by Jan-Erik Hägglöf 19 Jul '23

19 Jul '23

Dear All! I've been using emacs AUCTEX for quite a while and found it very convenient to work with. One issue is the lack of syntax highlighting. I've tried some elisp code and added the following hook when I'm in ConTeXt-mode: (add-hook 'ConTeXt-mode-hook (lambda () (font-lock-add-keywords nil '(("\\(\\\\starttext\\)\\>" 1 font-lock-warning-face t) ("\\(\\\\stoptext\\)\\>" 1 font-lock-warning-face t))))) and it seems to highlight the start-stop text keyword. So my question is: Is there a way to accomplish a similar way of highlighting all other keywords that belongs to the ConTeXt typesetting syntax? Maybe a REGEXP (I'm not good at writing those) can do this in some way without manually write every start-stop sequence that exists. Have anyone, using AUCTEX, already did some customizing already who wants to share it with me. Many thanks in advance /Jan-Erik

\placeinitial problem
by Alan Bowen 19 Jul '23

19 Jul '23

Hi— \placeinitial seems to fail when there is a footnote in the paragraph. At least \startparagraph \placeinitial \input ward \footnote{A footnote.} \stopparagraph only works when the footnote is commented out. I am running lmtx [ConTeXt ver: 2023.06.22 LMTX fmt: 2023.6.26] Alan

enhancing MetaPost presentation progress graphics
by Henning Hraban Ramm 19 Jul '23

19 Jul '23

Hi, I’d like a presentation progress indicator that looks like a boat on waves – and if it works, it can also become a bike on hills or a mars rover on dunes. But my math skills are lacking. Below’s a mostly working draft. * I find the waves not yet very convincing. Would it make sense to use a randomized sinus? (How?) * The boat should sit on the middle wave and be rotated by the current slope. I know I need the “time” of the upper curve and get the 1st derivation, but how? """ \setuppapersize[SW] \startuseMPgraphic{Waves} numeric height,stops,yoffset; stops := 10; height := OverlayHeight/10; path wave; draw (0,0)--(OverlayWidth,0)--(OverlayWidth,OverlayHeight) withcolor white withpen pencircle scaled 0.01; for j=1 upto 3: definecolor [name="Sea", y=(j/20), c=2*(j/10), m=(j/20)]; yoffset := height/(j*2); wave := (0,0)--(0,yoffset)... for i=1 upto stops: (OverlayWidth*i/(stops+1), (yoffset) randomized (height/2)) ... endfor (OverlayWidth,yoffset)--(OverlayWidth,0)--cycle; fill wave withcolor "Sea"; endfor; pair pos; pos := (OverlayWidth * RealPageNumber/NOfPages, height/2 randomized 2); path ship; ship := (0,10)---(70,10)...(60,0)---(10,0)...cycle; fill ship xysized (10,5) shifted pos rotatedaround (pos, 15) withcolor red; \stopuseMPgraphic \defineoverlay[Waves][\useMPgraphic{Waves}] \setupbackgrounds[state=repeat] \setupbackgrounds[page][background={Waves}] \starttext \dorecurse{10}{\recurselevel\page} \stoptext """ Hraban

Slow sreach with new mailing list interfache
by Michael Loescher 19 Jul '23

19 Jul '23

Hello, searching the mailing list is very slow recently (since the new interface hast been established). For example searching for "font" takes 20 seconds for the results to show up. Is it only me experiencing this phenomenon or ist it a general problem?
