\dontleavethemode
by Ursula Hermann 12 Sep '23

12 Sep '23

Dear List, I have done an little example with a \blackrule: \setuppapersize[A8,landscape] \setuplayout[leftmargin=2.5cm, leftmargindistance=0.2cm, backspace=2.9cm, width=4cm] \starttext \margintext{\blackrule[color=black, height=0.05ex, width=1cm]\\Me}\blackrule[color=black, height=0.05ex, width=4cm] \startformula a^n + b^n = c^n. \stopformula \stoptext My Question is , where to put margintext, with \dontleavethemode, with blackrule, because if I put it after \starttext: \margintext{\blackrule\\{Me}}\dontleavehmode\blackrule Before : \margintext{\blackrule[color=black, height=0.05ex, width=1cm]\\Me}\blackrule[color=black, height=0.05ex, width=4cm] there is no pdf after compiling.

XML: flush to lua function
by denis.maier＠unibe.ch 12 Sep '23

12 Sep '23

Hi, I have the following xml setup with a lua function: \startluacode function markingLength(s) _,n = s:gsub("%S+","") if n > 3 then context("yes" .. " ...") else context("no") end end \stopluacode \startxmlsetups xml:ink:ink-title:marking %\ctxlua{markingLength(\xmlflush{#1})} % does not work \ctxlua{markingLength{"1 2 3 4"}} \stopxmlsetups While the function works, I cannot use xmlflush here. How can I properly pass the xml content to the lua function? Best, Denis

Bug(?) in https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages
by Jim 11 Sep '23

11 Sep '23

Hi, In https://wiki.contextgarden.net/Tabulate#Spanning_Multiple_Pages the wiki has "internal error: convert failed". Removing \color[red] from \setuptabulate in that example gives a working example (at least in a separate file on my machine). I tried changing the title specification to title={\color[red]{Fenchurch St. Paul}}, as well as title={{\color[red]{Fenchurch St. Paul}}}, but both of these reward me with a runaway context process. Can someone point out the correct way to do what the wiki intended? Thanks. Jim P.S. Bonus question: should an incorrect use of color really cause an (apparent) infinite loop, or is that a second issue which deserves to be on some to-do list?

contextgarden server in Slovenia died last night

Hi, Unfortunately the contextgarden server in Slovenia died yesterday evening. We will let you know how this unfolds, but don't expect it back in a day. That includes: - meeting site (a copy was set up at https://meetingnl.contextgarden.net/) - context group site - the legacy distribution - build farm - CTAN mirror - a bunch more ... Mojca

Table of contents of unnumbered titles
by Jim 10 Sep '23

10 Sep '23

Hi, I am creating a document which is divided with the unnumbered levels (\title, \subject, ...). I would like a table of contents showing the names and page numbers, something like Blah blah blah 2 Blah blah 4 ... However, notwithstanding what I see in https://wiki.contextgarden.net/index.php?title=Titles&mobileaction=toggle_v… I can't get this to happen with unnumbered divisions. The above wiki reference says "the following might do that trick" but I think "might" is the keyword, since even the wiki doesn't show the "No number" entry in the \completecontent. I find it hard to imagine that I am the only Context user who wants to do this. Can anyone point me in the direction of a working example? And am I misinterpreting the wiki, or is the wiki page broken? Thanks. Jim

Verbatim Textbox with Reference NUmbering
by Jeroen 09 Sep '23

09 Sep '23

This is a longshot, but would be great to have. Below I have at MWE1 the verbatim codefragment textbox I am using. I found in the forum MWE2 which is a textbox with an automatic reference number. Is there a way to get the same for MWE1 with automatic reference numbering like 1.1, 1.2 etc for chapter 1, codefragment 1, 2 etc. with the possibility that in the text I can refer to the codefragment like \in{codefragment\space}[code:ccpsample] similar as to tables and figures?

how to define an environment with key=value arguments
by Henning Hraban Ramm 09 Sep '23

09 Sep '23

Hi, for an involved image placement (full page image starting each chapter, several stacked elements), I’d like an environment that accepts key-value arguments, like \startMyFigure[page=left,title={My caption}] \externalfigure[dummy]… \stopMyFigure I don’t think that a real float makes sense, even if the interface looks similar, since it’s always a full page in a fixed place, I need no numbering and can place the caption myself. Does it make sense to use \definestartstop? How would I “plugin“ the argument handling? Or should I better define start and stop separately? \def\startMyFigure[#1]{ % e.g. use utilities.parsers.settings_to_hash(#1) } \def\stopMyFigure{} Probably I’ll need to catch the content (\externalfigure, might become more) and use it in a \setlayer – so perhaps something like \definebuffer[MyFigure] \define\stopMyFigure{% \setlayer[page]{\getMyFigure}}} } ? But then I don’t know how to handle the arguments. Probably it makes most sense to do it in Lua, like \startluacode interfaces.implement { name = "startMyFigure", public = true, arguments = {"hash",}, actions = function(h, a) -- … end, } \stopluacode But I didn’t find how to do environments.

Text runs out of Verbatim Frame
by Jeroen 08 Sep '23

08 Sep '23

I am using the following to print some verbatim text in a frame. At the right side, it keeps running out of the frame, is there a way to prevent this with the MWE? This verbatim frame always is textwidth, is there a way for a single frame just for if the situation asks for it to have it only have a frame half pagewidth, like a width=0.5\textwidth Thanks Jeroen \unprotect \startuseMPgraphic{mpos:par:myexample} path p; for i = 1 upto nofmultipars : p := multipars[1] topenlarged 4pt bottomenlarged 4pt cornered 2mm ; fill p withcolor 0.95white ; draw p withcolor black withpen pencircle scaled \MPvar{linewidth}; endfor; \stopuseMPgraphic \definetextbackground [listingbackground] [state=start, mp=mpos:par:myexample, location=paragraph, topoffset=0.4em, leftoffset=0em, rulethickness=0.7pt] \definetyping[Listing] [option=commands] \setuptyping [Listing] [bodyfont=10pt, margin=1em, before=% {\blank[3*medium] \setupinterlinespace[line=2.4ex] \starttextbackground[listingbackground]}, after=% {\stoptextbackground \blank[4*medium]}] \protect \starttext \startListing test test test test test test test test test test test test test test test test test test test test test test test \stopListing \stoptext

textwide float too wide for text width
by Henning Hraban Ramm 08 Sep '23

08 Sep '23

Hi, a current observation: I have some floats with text wide images like: \startplacefigure[location=top] \externalfigure[dummy][width=\textwidth] \stopplacefigure These were moved to the last page until I decreased the width minimally (by 0.1 mm). So I guess there’s a rounding error somewhere. If that’s not obvious or a known feature, I’ll try to come up with a minimal example – I encountered it within a columnset, but don’t know if it’s related to columns or my own dimensions (\measure).

# verbatim typesetting
by Marcus Vinicius Mesquita 07 Sep '23

07 Sep '23

Dear List, The MWE below gives a pdf with two #'s instead of only one. Why is that? \starttext \startluacode context.type("#") \stopluacode \stoptext -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.
