Monospace fallback kerning
by Hans Åberg 19 Dec '18

19 Dec '18

In the example below, multiple spaces do not use the spacing of the fallback font for multiple spaces, but instead of the main font it seems, despite the ASCII U+0020 being in the forced override. So the question is how to force ConTeXt to use the fallback font also for multiple spaces. — \definefallbackfamily [mainface] [mono] [courier] [range={0000-00FF},force=yes] \definefontfamily [mainface][serif][stix] \definefontfamily [mainface][mono][stix] \definefontfamily [mainface][math][stix] \setupbodyfont [mainface,10pt] \starttext \starttyping code code . code . code . code code code . . code code . . . code code . . . . code code . code \stoptyping \stoptext —

\showhyphens
by Tomas Hala 19 Dec '18

19 Dec '18

Hi all, I would like to detect hyphen points in a paragraph. I hoped that the plain \showhyphens{text} can do it but it displays nothing. Is this plain macro available yet, or is it covered by other command? Thanks in advance. Best wishes Tomáš

Itemize lists run into floats - how to add additional spacing
by Marco Patzer 19 Dec '18

19 Dec '18

Hi! The bullet of itemize lists runs into the boxes and caption of floats. How to add spacing so the bullet doesn't touch the float? Example: \setupexternalfigures [location=default] \setupfloat [figure] [default=left] \setupitemize [packed, autointro] \starttext \startitemize \startitem Foo \startplacefigure [title=Lorem ipsum dolor sit amet consectetur] \externalfigure [hacker] \stopplacefigure Bar \stopitem \dorecurse{15}{%% \startitem Foobar \stopitem } \stopitemize \stoptext Marco

fallback family not working for \setinitial
by Pablo Rodriguez 19 Dec '18

19 Dec '18

Dear list, I have the following sample: \mainlanguage[agr] \setuppapersize[A5] \definefallbackfamily [mainface] [rm] [GFS Didot] [preset=range:greek, force=yes] \definefontfamily [mainface] [rm] [TeX Gyre Pagella] \setupbodyfont[mainface] \starttext \setinitial Πρῶτον δεῖ θέσθαι τί ὄνομα καὶ τί ῥῆμα, ἔπειτα τί ἐστιν ἀπόφασις καὶ κατάφασις καὶ ἀπόφανσις καὶ λόγος. \blank\setinitial Ὄνομα μὲν οὖν ἐστὶ φωνὴ σημαντικὴ κατὰ συνθήκην ἄνευ χρόνου, ἧς μηδὲν μέρος ἐστὶ σημαντικὸν κεχωρισμένον· \stoptext When the initial is a character from the extended Greek Unicode block, the fallback family doesn’t work for that initial. Could anyone confirm that this is a bug? Many thanks for your help, Pablo -- http://www.ousia.tk

searching in nodes
by Hans van der Meer 17 Dec '18

17 Dec '18

In a Lua function called from within an \startxmlsetups..\stopxmlsetups code block I would like to search through the current node and all below. Using string.match("to-be-searched”,”pattern”). The Lua function being called through \def\findmypattern#1#2{\ctxlua{tex.print(hvdm.findmypattern("#1","#2",))} But I do not seem to get the node contents in the first argument #1. Using \xmlverbatim{#1} fails with Lua error "hexadecimal digit expected near '"\xm’”. \xmlflushpure{#1} fails with Lua error "invalid escape sequence near …” Any help? dr. Hans van der Meer

Multiple image conversions
by Marco Patzer 16 Dec '18

16 Dec '18

Hi! I wonder if/how it's possible to specify multiple image conversions. Example: \startluacode local format = string.format local function degradejpg(oldname, newname) local s = format("gm convert -strip -quality 75%% -resize '300x300>' %s %s", oldname, newname) os.execute(s) end local function degradepng(oldname, newname) local s = format("gm convert -strip -resize '500x500>' %s %s", oldname, newname) os.execute(s) end figures.converters.jpg["degrade.jpg"] = degradejpg figures.converters.png["degrade.png"] = degradepng \stopluacode \setupexternalfigures [location=default, %% conversion=degrade.png, %% how to use both? conversion=degrade.jpg] \starttext \externalfigure [hacker] \externalfigure [mill] \stoptext I'd like to avoid specifying the filetype-specific conversion with each \externalfigure command: %% this works, but it clutters the document and one has to check the %% file type each time \externalfigure [mill] [conversion=degrade.png] Marco

table cell minimum heights -- help needed
by Taco Hoekwater 16 Dec '18

16 Dec '18

Hi all, I am attempting to process html tables that are styled using css, and I have problem with the ‘height’ property. CSS (or rather, the html browser) interprets ‘height’ as if it was a “minheight”, and if the content does not fit, it will just enlarge the height until it does fit. Needless to say: I want that same functionality from the ConTeXt table I am using to generate the PDF and not end up with text crossing row boundaries. And I cannot figure out how to do it, as neither bTABLE’s \bTD nor xtable’s \startxcell interpret a “minheight" parameter. And whatever I put in “height” becomes the absolute value of the cell height. Did I miss something? I cannot imagine that this problem has not come up before… Best wishes, Taco Example code: \starttext \bTABLE[frame=on] \bTR \bTD[height=20pt] \input tufte \eTD \eTR \eTABLE \blank[10*line] \startxtable[frame=on] \startxrow \startxcell[height=20pt] \input tufte \stopxcell \stopxrow \stopxtable \stoptext

unicode table in the fontloader
by Ulrike Fischer 14 Dec '18

14 Dec '18

Since 29.11 l-unicode.lua disables the slnunicode library with unicode = nil Functions from unicode.utf8 are used in various packages (latex and plain). They are documented in the luatex manual. Simply disabling them is not really an option for us. As we import l-unicode.lua through the lualibs package, this means that I currently have to revert the change manually. Would it be possible to disable the table only in context? Side question: are there any plans to remove the library from the binary? -- Ulrike Fischer https://www.troubleshooting-tex.de/

indented headings possible?
by Taco Hoekwater 14 Dec '18

14 Dec '18

Hi again, Is there a way to make section headings automatically honour the current left- and rightskip? For example, like this: \starttext \showframe \startnarrower[left] \section{Section 1} stuff \stopnarrower \stoptext I know I could rig this up with \dontleavehmode\vbox{\advance\hsize-\leftskip\section{Section 1}}\par but that is horrible code. Is there any way to get the correct effect using \setuphead ? Best wishes, Taco
