Placing margin notes on the left using Lua
by Hannes Riebl 20 May '15

20 May '15

Dear ConTeXt users, I am typesetting a critical edition with margin notes. To place these, I am using the Lua code below. It is based on the code from the LuaTeX wiki (cf. http://wiki.luatex.org/index.php/Post_linebreak_filter#Margin_notes) and has the restrictions mentioned on this wiki page. For example, placing notes on the left of the text is not possible. Now, my questions are: (1) How can I extend the code to place notes on the left of the text? I tried node.insert_before(line.list, line.list, glyph) but it did not work out. (2) How do I use the callback within the output routine to distinguish odd and even pages? Thank you very much for any hints or help! Best regards Hannes Riebl make_notes = function(head) for line in node.traverse_id(node.id("hlist"), head) do ... local glyph = node.new("glyph") glyph.font = font.current() glyph.lang = tex.language glyph.char = 97 node.insert_after(line.list, node.tail(line.list), glyph) ... end return head end nodes.tasks.appendaction("finalizers", "after", "make_notes") -- Hannes Riebl Abteilung Forschung & Entwicklung Georg-August-Universität Göttingen Niedersächsische Staats- und Universitätsbibliothek Göttingen D-37070 Göttingen Papendiek 14 (Historisches Gebäude, Raum 2.409) hriebl(a)sub.uni-goettingen.de http://www.sub.uni-goettingen.de http://www.rdd.sub.uni-goettingen.de http://dhd-blog.org

Controlling linespacing in a TOC
by Mari Voipio 19 May '15

19 May '15

Hello all! This is probably a stupid question, but how do I control the linespacing in a table of contents? I found that space can be added with e.g. \setuplist[chapter][before={\blank[4*big]}] but how do I make the linespacing smaller than default? I've got \setupwhitespace[medium] does that affect the linespacing in a table of contents? Are there any other settings besides \setuplist and \setupwhitespace that affect the TOC spacing? I've got a fairly complicated file (or, rather, a group of files), so I'm wondering if there's something somewhere else that makes my TOC so airily laid out. (It looks nice, but I'd rather squish it into fewer pages...) Thanks, Mari

creating multiline paragraph in \tabulate
by John Culleton 19 May '15

19 May '15

Supposedly \tablulate can handle a multiline paragraph in a single cell. It didn't work for me. The text just ran off the right edge of the page. So here is my two column table with a workaround. --------------------------------------------- \starttext {\bf Figure 2.3: Specialty Food Store Classifications} \setupframed[framecorner=rectanglular,background=none] \tfx \placetable[force,none]{} \starttabulate[|lw(.25\textwidth)|lpw(.75\textwidth)|] \HL ... \NC Housewares \NC Gourmet pots and pans and other cookware, with some impulse\NC\NR \NC \null \NC and companion food items \NC\NR ... \HL \stoptabulate \tf \stoptext ------------- In my version the \null command was necessary to skip the left column. Also, I want the title of the table at the top and not the bottom. So I have to add a separate title line at the top and blank out the generated title with a graphic of blank space placed below the table thus: \vskip -0.35in \externalfigure[blanker.pdf] There ought to be an easier way to get rid of the title at the bottom of the table but this is the best I could come up with. The file blanker.pdf was generated in Scribus 1.5.0 ---------------------------------------------------------------------- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html

backgroundscreen no longer working
by Thomas Floeren 19 May '15

19 May '15

Hi, backgroundscreen is no longer working here, apparently since the beta 2015-04-12. \starttext % \setupbackgrounds [page] [background=color,backgroundcolor=lightgray] \setupbackgrounds [page] [background=screen,backgroundscreen=.8] \input knuth \stoptext If I use the pack-rul.mkiv from 2015-04-08 it works again. Is it deprecated now, or is this just a bug? Thanks. -- Tom

XML filtering and \setupcombinations
by Michael Eidenbenz 19 May '15

19 May '15

Hello, I'm enjoying the power of the new publication framework and started to manage my images with it. This works quite nice. But now I reached the point where my (limited) context knowledge comes to an end. I would like to print a contact sheet of my large image database. To save paper I want combine floats next to each other. I use the XML framework to filter my images according the 'keywords' field: \usebtxdataset[image][../../4_source/2_image/1_image.bib] \convertbtxdatasettoxml[image] \startxmlsetups btx:render \xmlfilter {#1} { /bibtex /entry[@category='image'] /field[@name='keywords' and (find(text(), 'one'))] /.. /command(btx:figure) } \stopxmlsetups \startxmlsetups btx:figure \externalfigure [\xmlfirst{#1}{/field[@name='file']}] \stopxmlsetups \setupexternalfigures [location=global, directory={../../4_source/2_image}, width=3cm] \xmlsetup {btx:image} {btx:initialize} \starttext \xmlsetup {btx:image} {btx:render} \stoptext the file 1_image.bib has the following structure: @image{test_1, keywords = {one, two, three}, file = {test_1.png} } my problem is that I cant figure out how to process the filtered entries to form groups of let's say (3x4) twelve and use it with \ setupcombinations [3*4] Thanks for any help.

URLs in color including underbar
by Alexander Shukaev 18 May '15

18 May '15

Hello, So far I came up with the following solution: \setupurl[ style={\mono\underbar}, color={blue}, ] \def \url{% \dosingleargument \dourl } \def \dourl[#1]{% \begingroup \setupbar[% style={\urlparameter{style}}, color={\urlparameter{color}}, ]% \from[#1]% \endgroup } Is there a more natural way to make URLs appear in blue color including underbar? Thanks. Kind regards, Alexander

running MkI in context standalone
by Csikos Bela 18 May '15

18 May '15

Hello list members: I have context standalone installed on linux. Currently I use context like: open a terminal window source context-installation-path/tex/setuptex context filename.tex This runs contect MkIV according to log file. I would like to try MkII, but I didn't find information on how I can switch to it. (I searched for it in "ConTeXt reference manual", "ConTeXt / An excursion", contextgarden wiki pages.) What is the way to run MkII in standalone context? A link to the documentation regarding it also would be appreciated. Thanks, bcsikos

parenthesis in Arabic text
by Sam Ḥilluc 17 May '15

17 May '15

Greetings, I'm trying to typeset an Arabic text, but I have a problem with parenthesis in footnotes. The following example: \usemodule[simplefonts] \setmainfont[amiri][features=arabic,range=arabic] \setupdirections[bidi=global] \setupalign[righttoleft] \def\text{(ب)} \startdocument \text\footnote{\text}. \stopdocument gives the correct order in the text but the parenthesis are not adapted in the footnote. So in the text I get: (ب) And in the footnote: )ب(.
