XML - creating a list by hand (mkiv)
by Peter Rolf 13 Jan '10

13 Jan '10

Hi, can someone give me a helping hand with the following example. I still have no general survey over the XML related code in ConTeXt (donno what functions to use). The last time I played with it is one and a half year ago and many things have changed (meaning that the old examples no longer work). I simply want to create a XML document and insert some elements. My main problem is to insert an element at root level. I can insert an element before and after another element, but not into the element. I'm not sure, if I have understood the meaning of the pattern parameter correctly. Is this equal to XPath? %----- \starttext \startluacode local xmp = xml.convert("<?xml version='1.0' standalone='yes'?>\n<root>\n<bar>bla</bar>\n</root>") --xml.before(xmp,"/root/bar","foo") --xml.delete(xmp,"bar") --xml.inject(xmp,"/sub","bar")-- only for xml-files? xml.insert(xmp,"/root/bar","") --xml.inject(xmp,"/*/bar","") --xml.sprint(xml.filter(xmp,"/root/sub")) xml.save(xmp,"test.xml") \stopluacode \stoptext %----- Best wishes, Peter

simple layout
by Wolfgang Werners-Lucchini 12 Jan '10

12 Jan '10

Hallo, I need a little help for this simple layout. I am looking for a solution for hours now, but I can not get it work: ---------------------------------------------------------------- \setupcolors[state=start] \starttext \framed[background=color, backgroundcolor=gray]{% \starttable[|lp(.1\textwidth)|lp(.9\textwidth)|] \NC \placefigure[left,high]{none}{\framed[height=1cm]{graphic}} \NC Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts!\crlf Text rechts! \NC\AR % \NC Text rechts! \NC\AR \stoptable} Mehr Text \ldots \stoptext ----------------------------------------------------------------- left: picture (not always the same height) right: text (variable height, sometimes more, sometimes less than on the left) left and right framed (height should be the maximum of left and right height) after that: normal text. Problems: If height(left)>height(right) than height(framed) is not height(left) 'Mehr Text' is not left aligned Wolfgang

Thanks, Wolfgang! Good toy ) \usemodule[ruby] \define[1]\chord{\dontleavehmode\ruby[position=before,align=left,inbetween={\blank[big]}]{}{#1}} \starttext \setupinterlinespace[big] \startlines \chord{E}Cvet dišeč z \chord{H7}jutrom se od\chord{cis}pre, \chord{A}sonce od\chord{E}pira o\chord{H}či. \chord{E}Polje z vetrom v \chord{H7}plesu ziblje \chord{cis}se. Gos\chord{E}pod, pov\chord{H}sod vidim \chord{E}Te. \stoplines \stoptext However, it was tricky to find out that "inbetween={\blank[big]}"key controls the distance between chords and lyrics. Can this distance be set more precisely? And "position=before" or "after" would better be "above" and "below", respectively. Don't you dare to change this? ) Regards, Vyatcheslav

Thanks for answers, friends! I don't have ruby installed, so I try Mojca solution. It works perfectly (thanks!), except I need to wrap the lyrics into the 'lines' envinroment. To achieve this, I need to replace \setupwhitespace with \setupinterlinespace and adjust raisebox amount. \starttext \def\Ch#1{% \strut\hbox to 0pt{\raisebox{0.45\baselineskip}\hbox{\bf#1}\hss}} \setupinterlinespace[big] \startlines \Ch{E}Cvet dišeč z \Ch{H7}jutrom se od\Ch{cis}pre, \Ch{A}sonce od\Ch{E}pira o\Ch{H}či. \Ch{E}Polje z vetrom v \Ch{H7}plesu ziblje \Ch{cis}se.

Using frames with metapost background in metapost
by Aditya Mahajan 12 Jan '10

12 Jan '10

Hi, I want to use a frame with metapost background to highlight some text inside metapost. But, the best that I can do is get metapost to typeset the code for the background, rather than execute it! Any ideas on a work around (in MkIV). \startmode[error] \defineoverlay[MP:background] [\useMPgraphic{MP:backgound}] \startuseMPgraphic{MP:backgound} draw OverlayBox randomized 9pt withcolor blue; \stopuseMPgraphic \stopmode \defineframed[boxframed][frame=on,background=MP:background] % A frame defined with \defineframe does not work % inside Metapost, so I prevent expansion. \unexpanded\def\boxed#1{\boxframed{#1}} \starttext \boxed{Boxed in text} \startMPcode draw textext("\boxed{boxed in metapost}") ; %draw textext("\boxframed{boxed in metapost}") ; \stopMPcode \stoptext Thanks, Aditya

Verbatim Text with Embedded Formatting Commands (MkIV)
by Tad Ashlock 11 Jan '10

11 Jan '10

As noted at http://wiki.contextgarden.net/Verbatim_text#Embedded_formatting_commands, the embedded formatting commands in verbatim text don't work in MkIV. Are there any plans to fix this capability soon? I'm planning on working on a project on over the holiday break that will need it. I'm not pushing to change your priorities. If it's not going to be fixed soon, then I'll implement a simple verbatim module that supports embedded formatting commands that will do until the official module works. I just don't want to waste that effort if verbatim is going to be fixed soon anyway. Thanks, Tad Ashlock

Minimals and XeTeX
by Vedran Miletić 11 Jan '10

11 Jan '10

Hi, I'm a new user of ConTeXt and minimals distribution and first I would like to say to thank everyone involved in it. Like most LaTeX users, I found something that was very hard to do in LaTeX to be fairly trivial in ConTeXt, and gave it a shot. Nevertheless, there is an issue with missing files that might be relevant and worth noting here. When compiling with --xtx, texexec (or xdvipdfmx) warns about missing dvipdfmx.cfg (that should, according to TeX Live structure, be in texmf/dvipdfmx/dvipdfmx.cfg), and once you manually add that, about missing cid-x.map (texmf/fonts/map/dvipdfmx/cid-x.map). After adding both files, there are no more complains. Can those files be added to minimals distribution? -- Vedran Miletić
