My example, with \blackrule, works perfect
by Ursula Hermann 13 Sep '23

Dear List, I just finished my example, did some changes today and it works perfect \setuppapersize[A8,landscape] \setuplayout[leftmargin=2.5cm, leftmargindistance=0.2cm, backspace=2.9cm, width=4cm] \margintext{\blackrule[color=black, height=0.05ex, width=1cm]\\}\blackrule[color=black, height=0.05ex, width=4cm] \starttext \margintext{2.1.1}\ {Ach ist das schön, dass du da bist.} \stoptext Uschi

Re: Using structureuservariables before the heading
by Andres Conrado Montoya 12 Sep '23

You can find some examples in the wiki to do something similar: https://wiki.contextgarden.net/Generate_Authorlist_from_Head_Content Also you can use setups instead of macro definitions, and create spaces with \space, \par, etc: https://wiki.contextgarden.net/Setups -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.

by Jeroen 12 Sep '23

Is there an easy way to reduce the line space between rows in a natural table so the table takes less vertical space. Thanks, Jeroen

\dontleavethemode

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?
