Setting starting chapter number
by Tom 23 Feb '11

23 Feb '11

I have the need to start a document on a chapter number greater than 1 but cannot find the command that sets the starting chapter number. I assume that such a command exists and have probably overlooked the right one. Tom Benjey 717-258-9733 voice 717-243-0074 fax blog: www.TomBenjey.com

\stretched in chapter titles in MKII
by Tom 23 Feb '11

23 Feb '11

I am trying to stretch two lines of text to the same width for use as a chapter head. I have two major problems: 1. The second line of text is appended to the end of the first line instead of being placed below it. 2. I get errors when using #1 and #2 as values, i.e {Chapter #1} and {#2}. Because of these errors I have hardcoded the values in the example that follows: \def\MyChapterCommand#1#2% #1 is number, #2 is text {\hbox to \hsize {\ss\stretched{Chapter 1}} \par \hbox to \hsize {\ss\bf\stretched{Test Chapter Title}}} \setuphead[chapter] [command=\MyChapterCommand] \starttext \chapter{Test Chapter Title} \input knuth \stoptext Tom Benjey 717-258-9733 voice 717-243-0074 fax Twitter: @TomBenjey

Latest betas break tikz matrix
by Mathieu Boespflug 23 Feb '11

Hi all, This code used to compile in versions of context prior to January, though I can't quite pin down the versions. \usemodule[t-tikz] \usetikzlibrary{matrix} \starttext \tikzstyle{description}=[fill=white,inner sep=2pt] \starttikzpicture \matrix(m)[matrix of math nodes, row sep=3em, column sep=3em, text height=1.5ex, text depth=0.25ex] {x&y\\ z&u\\}; \path[->] (m-1-1) edge node[description] {$*$} (m-1-2) edge node[description] {$*$} (m-2-1) (m-1-2) edge[dashed] node[description] {$*$} (m-2-2) (m-2-1) edge[dashed] node[description] {$*$} (m-2-2); \stoptikzpicture \stoptext (compilation error at the bottom of this email) I thought at first that this was a luatex problem, but I've ruled that out with the following plain tex file, which compiles just fine in plain luatex and in plain pdftex: \input tikz.tex \usetikzlibrary{matrix} \tikzstyle{description}=[fill=white,inner sep=2pt] \tikzpicture \matrix(m)[matrix of math nodes, row sep=3em, column sep=3em, text height=1.5ex, text depth=0.25ex] {x&y\\ z&u\\}; \path[->] (m-1-1) edge node[description] {$*$} (m-1-2) edge node[description] {$*$} (m-2-1) (m-1-2) edge[dashed] node[description] {$*$} (m-2-2) (m-2-1) edge[dashed] node[description] {$*$} (m-2-2); \endtikzpicture \end I have no idea what the error is telling me and what could be causing it. Any ideas? Many thanks, Mathieu Compile log: !

\useexternalfigure globally? (+minor issues)
by Philipp Gesang 22 Feb '11

22 Feb '11

Hi all, [1] in grph-fig.mkiv, “\useexternalfigure” is declared twice in exactly the same way (ll. 124 and 132). [2] “\showexternalfigures” does not seem to work in mkiv (fails at “\startXMLmapping”), is there an alternative? [3] Is there a way to globally declare an externalfigure from inside a group? So that in the following example, the second reference to “kuh” succeeds. ···8<···························································· \starttext \bgroup \useexternalfigure[kuh][cow] \externalfigure[kuh] \egroup \externalfigure[kuh] \stoptext ···8<···························································· Thanks in advance, Philipp

about the line break after \inframed
by Jeong Dalyoung 22 Feb '11

22 Feb '11

Dear all, I tested the following code from Metafun. \startuseMPgraphic{lions b} picture pic; path p ; p := fullsquare xyscaled (\overlaywidth,\overlayheight) randomized 5pt ; pickup pencircle scaled 1pt ; fill p withcolor .850yellow ; draw p withcolor .5yellow ; \stopuseMPgraphic \defineoverlay[leopard][\uniqueMPgraphic{lions b}] \def\nota#1 {\inframed[frame=off,background=leopard]{#1}} \starttext \nota{test 1:} This is a test for line separation. %\midaligned{\nota{test 2}} \stoptext Then the sentence "This is a test." is written in a new line as following. test 1: This is a test. Q1. I'd like to have it in the same line as "test 1: This is a test." How to surpress the line break after test? Q2. Also, if I try to add \midaligned{}, then an error occured. .... ! Argument of \nota has an extra }. ... ... <inserted text> \par <to be read again> } l.15 \midaligned{\nota{test 2}} How to put it midaligned? Thank you. Best regards, Dalyoung

Did anyone on this list know (or did anyone notice yet) that the print version of the much-discussed dissertation by Karl-Theodor zu Guttenberg was (allegedly) typeset in ConTeXt?

Learning LuaTeX : Invoice
by Henning Hraban Ramm 22 Feb '11

22 Feb '11

Maybe similar to the "spreadsheet" question: I'm trying to use Wolfgang's letter module for my invoices and would like to use Lua for the sums. But I fail already at the beginning: \startluacode userdata = userdata or {} userdata.invoice = userdata.invoice or { sum = 0 } -- global table for sums function userdata.singlesum(hours, perhour) amount = hours * perhour userdata.invoice.sum = userdata.invoice.sum + amount global.context(string.gsub(string.format("\%.2f", amount), "%.", ",")) return amount end \stopluacode gives: (virtual://viafile.1 unknown preamble key [the character )] unknown preamble key [the character )] unknown preamble key [the character )] ! LuaTeX error <main ctx instance>:1: '=' expected near '<eof>'. system > tex > error on line 11 in file invoice.tex: LuaTeX error ... 4 \startluacode 5 userdata = userdata or {} 6 7 userdata.invoice = userdata.invoice or { sum = 0 } 8 9 function userdata.singlesum(hours, perhour) 10 amount = hours * perhour 11 >> userdata.invoice.sum = userdata.invoice.sum + amount 12 global.context(string.gsub(string.format("\%.2f", amount), "%.", ",")) 13 return amount 14 end I can't see what's wrong!? I tried local and usercode, but didn’t get further. Greetlings from Lake Constance! Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

filtering xml
by Thomas Schmitz 22 Feb '11

22 Feb '11

Hi all, this must be easy, but I don't find the solution. Given an xml structure like this: <X> <A>dog</A> <A>cat</A> <A>mouse</A> </X> which \xmlfilter expression do I need to get the first <A> element which has a subelement ? I.e., the filter should only return "cat," not "dog" or "mouse." There can be 0 or more elements without before and after the one I want to retrieve. Sorry if this is elementary, but I looked at xml-mkiv.pdf and mk.pdf and couldn't find an answer. Thanks Thomas
