rotation weirdness
by Hans van der Meer 16 Sep '23

16 Sep '23

I encountered something weird, that I cannot explain. It could be an error, but I was not able to pinpoint this. It seems as if the \rotate macro plays havoc with the macro definitions used to set the color of the frame and an outside title. Placing the outside title before the rotate proves that the call to \rotate is the culprit. I enclose an MWE with a little jpeg figure as illustration. yours sincerely dr. Hans van der Meer \def\formattitle#1{\color[\boxtitlecolor]{#1\strut}} \def\boxfigurerotate#1#2{% \rotate[rotation=10]% {% \externalfigure[#1]% [rulethickness=4pt,width=100pt,height=50pt,frame=on,framecolor=\boxframecolor,]% }% \formattitle{#2}% } \def\boxfigure#1#2{% \externalfigure[#1]% [rulethickness=4pt,width=100pt,height=50pt,frame=on,framecolor=\boxframecolor,]% \formattitle{#2}% } \def\boxtitlecolor{blue} \def\boxframecolor{blue} \starttext \ConTeXt\ \contextversion \blank Problem:\crlf it looks like \type{\rotate[]{}} kills the definition of boxtitlecolor.

Re: streams reversed?
by jbf 16 Sep '23

16 Sep '23

My feeling at the moment is that this might be about the only way one could go ahead in a production situation, and yes, I am familiar with PDF tools that can achieve this, though it is effectively stepping aside from ConTeXt and working with PDF. For that matter I can easily go ahead with a commercial program that solves all the problems thus far indicated. I think it is true to say that at the moment, the streams mechanism is far too klunky to be able to use it extensively. For a handful of pages (and especially if the two streams re absolutely equal in length) it is workable. Beyond that, at least for the moment, it is not, and I am afraid I do not have the luxury of time to try to refine it. Your efforts, Bruce, are hugely appreciated, but also confirm the difficulties faced thus far.

Then merge frontmatter and back matter. If you are reasonably familiar with PDF splitting / joing tools then this might be the simplest solution.

Chapters without new page
by Jeroen 15 Sep '23

In the \startbackmatter ... \stopbackmatter section i would like to have some chapters that are not automatically placed on a new page for the next chapter. Is there an easy way to suppress the new page for these chapters? Thanks, Jeroen

Using structureuservariables before the heading
by denis.maier＠unibe.ch 14 Sep '23

14 Sep '23

Hi, is it possible to access a structureuservariable before the heading's title ? Using the <before> key does not seem to work. As an aside, I've tried to use the < command > key to provide my own command, but while \define works here (but ignores \blank), \def gives me an error. Why is that? How would you add blanks to a user-defined command? Best, Denis \setuphead[chapter][ before={Before: \structureuservariable{author}\blank}, beforesection={Beforesection: \structureuservariable{author}\blank}, insidesection={Insidesection: \structureuservariable{author}\blank}, after={After: \structureuservariable{author}\blank}, ] \def\myChapterCommand#1#2{\structureuservariable{author}\space\blank} \define[2]\myChapterCommand{\structureuservariable{author}\blank #1\space#2} %\def\myChapterCommand#1#2{\structureuservariable{author}\blank #1\space#2} % does not work \starttext \macro{1}{2} \startchapter[title=First][author=First Author] \input knuth \stopchapter \startchapter[title=Second][author=Second Author] \input knuth \stopchapter \setuphead[chapter] [ before=,after=,beforesection=,insidesection=, command=\myChapterCommand, ] \startchapter[title=Third][author=Third Author] \input knuth \stopchapter \stoptext

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

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.

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

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
