Attachment marks to be aligned horizontally
by Procházka Lukáš Ing. - Pontex s. r. o. 19 Jan '15

19 Jan '15

Hello, marks of attachments in the attached MWE are aligned in the following way: - after A and C - horizontally, - after B - vertically. The only difference is that \blank precedes in the B case. So - how to force horizontal alignment for attachment marks in the B case, supposing that \blank before is necessary for any reason? The code follows: ---- \setupinteraction[state=start] % \starttext A \attachment[t-Att2.mkiv] \attachment[t-Att2.mkiv] \startitemize[][] \item B \blank \attachment[t-Att2.mkiv] \attachment[t-Att2.mkiv] \item C \attachment[t-Att2.mkiv] \attachment[t-Att2.mkiv] \stopitemize \stoptext ---- TIA.

How to draw this picture?
by Rob Heusdens 17 Jan '15

17 Jan '15

I am working on an economic book, which I convert from a paper edition into a digital edition, which contains some figures I want to recreate using context or other tool. In logical terms, the picture represents some economic figures and visualizes how some figure (e.g. "National income" and the amount) is the sum of some other figures, in which it can be split up. In logic terms the figure then explains that: A can be split up into B and C. B can be split up into D and E. D is F. E can be split into G,H,I and K. Graphically this is depicted like a table containing 4 columns and 5 rows, and the "split into" is drawn as two diagonal lines (one right-up and another righ down) which shows how the element on the left column is split up into the elements on the right column using the diagonal lines that center in the left element, drawn to the right top and right bottom element. I worked this out into context as a simple table, and used instead of the diagonal lines only vertical lines. Which is less expressive, but still visualizes the splitting sufficiently I hope. But I would like to rework this picture, using a brace instead of a vertical line, similar to how in a formula one uses mathcases. I tried to use mathcases, but it seems mathcases can't be nested?? I was thinking of other solutions, like replacing the vertical line with a small column in which to put a vertical stretched brace symbol, at the appriopriate lowered cell, but don't know how the vertical stretch a glyph. What is the best way to code this in ConText? (preferred is to use the symbol left brace.)

"someone who can fix can fix"
by Henning Hraban Ramm 15 Jan '15

Hi again, I’m trying to get my invoice setup working again. The error message is: close source > 3 > 12 > invoicefunctions.tex tex error > error on line 75 in file virtual://buffer.608>letter.1: ! This can't happen (linebreak_tail) \spac_vspacing_yes_indeed ...>\ifmmode \else \par \ctxcommand {vspacing("#1"... l.75 \blank[2*big] <empty file> I'm broken. Please show this to someone who can fix can fix I don’t know where to start looking, I guess it’s something with the letter module. The same files used to work at least until November 2014 and stopped somewhen end of 2014. So far I failed to cook up a minimal example, I’ll gladly prepare one if you can point me to something that might be the cause.

adapt fontsize to given width
by Pablo Rodriguez 14 Jan '15

14 Jan '15

Dear list, I have the following sample: \showframe \starttext {\setupbodyfont[120pt]My Title} \stoptext Is there a way to make ConTeXt automatically calculate the size of the \setupbodyfont, so that the passage fits exactly to text width? Many thanks for your help, Pablo -- http://www.ousia.tk

Center two frames

Catalan especial character (l·l) in ConTeXt
by 19cat 14 Jan '15

14 Jan '15

Hello, I am Catalan, and we use frequently the geminated character ( l· ), that not is showed correctly in ConTeXt. Dot is too much separated of 'l' characters. How can I control character spacing by default? I have seen Fontfeaturefiles page in wiki for create ligatures and control kerning. But my attempts have failed. Do you think it is a good choice? I keep trying? Explanation extended: ================= Typing normally, catalans use "flow dot" character ( · ) between 'l' (l·l), that in spanish keyboard is located over key '3'. Other option is use special utf-8 characters (Ŀ) and (ŀ), but this character is not in any keyboard, and must changed before compile with ConTeXt (I use SED command). But none of these options is good. See you the result of following sample in context. % =================================== % Sentence: "I want to see films at school" \mainlanguage[ca] \starttext % With flow point \section{PEL·LÍCULES} Vull veure pel·lícules al col·legi % With utf-8 character \section{PEĿLÍCULES} Vull veure peŀlícules al coŀlegi \stoptext % =================================== The first result is very bad (too separaded). The second result is better, but closer together. More than double L ( ll) I would obtain LaTeX result using special characters that are more separated than ConTeXt, using "flow point" of keyboard. See you this sample: % =================================== \documentclass[a4paper]{article} \usepackage[utf8]{inputenc} \usepackage[catalan]{babel} \usepackage[T1]{fontenc} \usepackage{lmodern} \usepackage{newunicodechar} \newunicodechar{Ŀ}{Ŀ} \newunicodechar{ŀ}{ŀ} \newunicodechar{Ŀ}{\L.} \newunicodechar{ŀ}{\l.} % Sentence: "I want to see films at school" \begin{document} % With flow dot \section{PEL·LÍCULES} Vull veure pel·lícules al col·legi % With utf-8 characters \section{PEĿLÍCULES} Vull veure peŀlícules al coŀlegi \end{document} % =================================== The second section is with utf-8 characters, and it looks great. Thanks, 19cat

ignoring an element in XML
by Pablo Rodriguez 12 Jan '15

12 Jan '15

Dear list, I have an XML document with <h1> different elements. I want to parse the vast majority of them, but not the ones that are wrapped in a <div class="hidden"> element. Which is the right way to do it? The following doesn’t work: \xmlsetsetup{\xmldocument}{div[@class='hidden']/h1}{} Many thanks for your help, Pablo -- http://www.ousia.tk

figure caption question
by j. van den hoff 12 Jan '15

12 Jan '15

hi, I have some problems with adjusting figure captions. what I want: 1. constant caption width across all figures, possibly identical to text width 2. trailing the auto-incrementing figure number with a fixed character, e.g. a `:', while still being able to cross-reference to the figure without the `:' occuring as part of the reference (i.e. it should read "Figure 1: caption_goes_here" and the cross-reference then should read "see Figure 1" rather than "see Figure 1:". Using something like \setupcaptions[width=0.9\textwidth, numberstopper={:}] sort of works except that cross references than include the "numberstopper" `:' in the reference ("see Figure 1:") which is really awkward. so how can this be solved (adjust the numberstopper in the caption without affecting how the figure label/number appears in cross-references)? regarding the caption width it seems that of the predefined keywords (fit, broad, max) only the first one is understood correctly (presuming it means "fit to figure width" -- I did not find an explanation anywhere). `width=max' does not maximize the width (rather it is smaller than with `width=fit' in some of my figures) and `width=broad' throws an error ("! Missing number, treated as zero" etc.). what am I missing regarding these keywords? thx/j -- Using Opera's revolutionary email client: http://www.opera.com/mail/

dealing with footnotes and ol in XML
by Pablo Rodriguez 11 Jan '15

11 Jan '15

Dear list, I have the following sample: \startbuffer[demo] <doc> This is the first paragraph. <ol> <li>first item</li> <li>second item</li> </ol> text with footnote<a href="#fn1" class="footnoteRef" id="fnref1">1</a> text with another footnote<a href="#fn2" class="footnoteRef" id="fnref2">2</a> <div class="footnotes"> <hr /> <ol> <li id="fn1">footnote text In two paragraphs<a href="#fnref1">↩</a></li> <li id="fn2">footnote text In two paragraphs<a href="#fnref2">↩</a></li> </ol> </div> </doc> \stopbuffer \starttext \usemodule[html] \startxmlsetups xml:initialize \xmlsetsetup{#1}{*}{xml:*} \xmlsetsetup{\xmldocument}{a[@class='footnoteRef']}{xml:footnote} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:footnote \startfootnote \xmlfirst{main}{div[@class='footnotes']/ol/li[(a)id=string.sub('\xmlatt{#1}{href}',2)]} \stopfootnote \stopxmlsetups \setupitemize[margin=yes] \xmlprocessbuffer{main}{demo}{} \stoptext The first issue I’m experiencing is that I don’t know how to avoid that footnotes (implemented in XML as items in an ordered list) are also typeset as list items. Footnotes may be inside lists or contain lists, but footnotes themselves are only implemented as lists. The only way I know is to disable lists, but this is not an option. The second issue is that \setupitemize[margin=yes] doesn’t work. What am I missing here? Many thanks for your help, Pablo -- http://www.ousia.tk
