luatex 0.75 and Debian Wheezy
by bbvogel＠home.nl 05 Mar '13

05 Mar '13

Hi, Debian Wheezy (soon to be released) uses GLIBC_2.13, so this error is expected. texlua: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by texlua) Regards, Bernard

Trouble with \placefloat in recent versions of the standalone
by Robert Blackstone 05 Mar '13

05 Mar '13

Dear all, With recent standalones (jan. 7, jan. 29 and march 2) I am experiencing trouble processing .tex-files that gave no problems in november (14-11). For instance, when processing with "ConTeXt ver: 2013.01.02 18:19 MKIV fmt: 2013.1.7 int: english/english", the log file gives the following information: ------------------------------------------------------------------- ! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\s'. system > tex > error on line 47 in file Chapter_4_S2MyBq-02-03-example.tex: LuaTeX error ... ------------------------------------------------------------------- and further on: ----------------------------------------------------------------- 45 \placeexample[here][ZarlConsCh38p188tot]{Zarlino\index[Zarlino]{Zarlino, Gioseffo}, Consonances ch.38, p.188} 46 {\startcombination[1*2] 47 >> {\externalfigure[ZarlConsCh38p188fa]}{facsimile} 48 {\externalfigure[ZarlConsCh38p188fi]}{transcription} 49 \stopcombination} ---------------------------------------- The processing stops at line 47. The log-file's last words are: "<inserted text> ...number \foundexternalfigure ; }" I have no clue as to what to do with that information. Just for the sake of completeness: In the setupfile "example" is defined: \definefloat[example][examples] \setupcaption[example][way=bychapter,prefix=yes,prefixsegments=chapter,location=top,number=yes,inbetween=\blank,bodyfont=10pt] \setuplabeltext[en][Example=Ex. ] As said, "ConTeXt ver: 2012.11.14 11:37 MKIV fmt: 2012.11.15 int: english/english" gives no problem at all. Also, \placetable[here][tab:ref]{caption}} does not seem to trigger problems in recent versions. Has something been changed in the commands for placing external figures since november? What would I have to change, either in the setup or in the commands for placing the example? Thanks in advance for any help. Best regards, Robert Blackstone

XML Lua engine in ConTeXt
by Procházka Lukáš Ing. - Pontex s. r. o. 05 Mar '13

05 Mar '13

Hello, which XML processing Lua engine is used by ConTeXt? There are more XML processors developed for Lua - LuaXML, LuaExpat etc. Does ConTeXt use one of these or another, or its own - a built-in one? As I'm processing XML tables with pure Lua, too, I'd like to use only one engine in pure Lua scripts and within ConTeXt; I believe it could be possible. Best regards, Lukas -- Ing.

processing xml with lua
by Schmitz Thomas A. 05 Mar '13

05 Mar '13

Hi all, one of my favorite topics… Here is a minimal example which shows something that I don't understand: when I process the subsection with the lua code, I want to get the value of the current section's "label" attribute in xml.attribute(r, "../../section", "label", "X"). So i was expecting that lua would go up (../../) and fetch the current section's label. But if you run the example, you see that it actually always gets the first section's label (value is always 1). How can I get the current section's label with a lua function? THanks and all best Thomas \startbuffer[test] <chapter> <section label="1"> <subsection label="1"> <content> text 1.1 </content> </subsection> </section> <section label="3"> <subsection label="1"> <content> text 3.1 </content> </subsection> <subsection label="5"> <content> text 3.5 </content> </subsection> </section> </chapter> \stopbuffer \startxmlsetups xml:testsetups \xmlsetsetup{\xmldocument}{chapter|section|subsection|content}{xml:*} \stopxmlsetups \xmlregistersetup{xml:testsetups} \startxmlsetups xml:chapter \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:section \xmlflush{#1} \par \stopxmlsetups \startxmlsetups xml:subsection \xmlfunction{#1}{test} \stopxmlsetups \startluacode outfile = io.open('temp.tmp', 'w') function xml.functions.test(r) content = xml.text(r, "content") section = xml.attribute(r, "../../section", "label", "X") context("This ") context(content) context(" is in section ") context(section) end \stopluacode \starttext \xmlprocessbuffer{main}{test}{} \enabletrackers[context.trace] \xmlshow{main} \stoptext

Understanding \lesshyphens
by Marco Patzer 04 Mar '13

04 Mar '13

Hi, how is \lesshyphens supposed to work? According to the source it's supposed to increment the current value of lefthyphenmin and righthyphenmin. But apparently I'm mistaken, it has no effect whatsoever. Can someone enlighten me? \setuplayout [width=3cm] %% \setuplanguage [lefthyphenmin=3] %% works \lesshyphens %% no effect \starttext \input zapf \stoptext Marco

Hello all, I'm learning a little bit of metapost language, using metafun manual. I made some background for a title (surely the code is awful, thanks for suggestions of improvement) but it's static, i'd like to adapt it to the widthof the text.

recalculate background on every page with \uniqueMPgraphic?
by Mikael P. Sundqvist 04 Mar '13

04 Mar '13

Dear list, with the (almost minimal) example below, I hoped that the frame would be recalculated at every page. But it is not (they all look the same in my output pdf). How can I force the frame to be redrawn at every page? Btw, If I change the uniqueMPgraphic to useMPgraphic (everywhere) my file does not compile anymore. I get some lua error. /Mikael \setuppapersize[S6][S6] \setuplayout[ width=fit, height=fit, margin=1pt, topspace=0.5cm, headerdistance=0.3cm, footerdistance=0.5cm, footer=14pt, backspace=1.5cm, location=middle, ] \startuniqueMPgraphic{figram} path q; rr:=7mm; StartPage; q := lrcorner Field[RightMargin][Header] -- llcorner Field[LeftMargin][Header] -- ulcorner Field[LeftMargin][Footer] -- urcorner Field[RightMargin][Footer] -- cycle; draw q withcolor 0.7white; draw (urcorner q)--((urcorner q) xshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (urcorner q)--((urcorner q) yshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (ulcorner q)--((ulcorner q) xshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (ulcorner q)--((ulcorner q) yshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (llcorner q)--((llcorner q) xshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (llcorner q)--((llcorner q) yshifted -1bp-(uniformdeviate rr)) withcolor .7white; draw (lrcorner q)--((lrcorner q) xshifted 1bp+(uniformdeviate rr)) withcolor .7white; draw (lrcorner q)--((lrcorner q) yshifted -1bp-(uniformdeviate rr)) withcolor .7white; StopPage; \stopuniqueMPgraphic \defineoverlay[figram][\uniqueMPgraphic{figram}] \setupbackgrounds[page][background=figram] \starttext \dorecurse{10}{\input knuth} \stoptext

FiXme and ConTeXt mkiv
by Janne Junnila 04 Mar '13

04 Mar '13

Hi all, I was trying to use the FiXme module today, but it seems like it is using some macros that are only available in mkii. Does anyone know of any alternatives? (Or is anyone planning on porting FiXme to mkiv?) Thanks, Janne Junnila

About Chapter head definition and FunnyFrame
by Jeong Dalyoung 03 Mar '13

03 Mar '13

Dear all, I have two questions. 1. I defined \Myheader and use it to shape the chapter head as following: \def\Myheader#1#2{% \framedtext [width=\overlaywidth, height=9\bodyfontsize, background=color, backgroundcolor=lightgray, offset=2pt, strut=no, frame=off, align={middle, middle}] { {\tfb 제 #1 장} \blank[big] {\sans #2} }} \startsectionblockenvironment[bodypart] \setupheadertexts[][{\tfx COUNTING}] \setuppagenumber[number=1] \setuppagenumbering[alternative={singlesided,doublesided},location={footer,right}] \setuphead[chapter][command=\Myheader,before={\dontleavehmode\blank[2*big]},after={\blank[5*big]}, page=right] \stopsectionblockenvironment …. \chapter{The Addition Principle \crlf {\tfx Sum Rule}} …. But it produces an error which is … ! Argument of \Myheader has an extra }. system > tex > error on line 94 in file SumRule.tex … What is wrong in this code? 2. I used "funnyFrame" defined in the MetaFun book. It works fine except that it is left aligned. I'd like to put such a frame in the middle. But \startalignment[middle] didn't work. Is there any way to make FunnyFrame center aligned? Thank you for the reading. Best regards, Dalyoung
