line numbers in margin from xml in context mkiv
by Jon Crump 27 Apr '11

27 Apr '11

All, After being away from my project for a while I returned to find that something that worked now no longer does. I updated the minimals on my Mac and context is running as I would expect: jjc% context --version mtx-context | main context file: /Users/jjc/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2011.04.24 15:15 But now, while running my environment.tex file against my target TEI/xml file context complains: ! Undefined control sequence. l.77 \defineinmargin [lineNumbers] [normal] ? My own fragile understanding of what I'm doing may well be at fault, but perhaps something relevant has changed with the minimals? I had an environment file that I'd arrived at by much trial and error that renders page/line numbers encoded in the xml/TEI source in the margins of my pdf output: \startxmlsetups xml:pb \def\svopage{\xmlatt{#1}{n}.} \xmlflush{#1} \stopxmlsetups \startluacode function filter(lb) if math.mod(lb,5) == 0 then context.svopage() context(lb) end end \stopluacode \define[1]\MyNumber% {\ctxlua{filter(#1)}\endgraf} \startxmlsetups xml:lb \xmldoifelse{#1}{ancestor::head[@type='diarytitle']} {\\} {\lineNumbers{\tfxx\MyNumber{\xmlatt{#1}{n}}}} \xmlflush{#1} \stopxmlsetups \defineinmargin [lineNumbers] [normal] Any suggestions would be gratefully received.

Layers again
by Ian Lawrence 26 Apr '11

26 Apr '11

I have a layer that I'd like to appear on some pages but not others, and for which I'd like to switch the content by page. (I need the layer to precisely and reliably locate some graphics. However, as I see it, you can only set the visibility of a layer in \definelayer, \setupbackgrounds - and these ought to preceed \starttext Any pointers / elegant suggestions / neat solutions? Thanks Ian

Context and metapost: using \frac
by mat 26 Apr '11

26 Apr '11

Hi I am using context to run a metapost graph. I am however unable to insert a label with \frac, since this is not pure Tex but Latex. This seems to be a known problem for metapost: -Seems for metapost only, one should add %&latex (http://ryanmlayer.wordpress.com/tag/metapost/) -I saw also one post where it was mentione done should add //\setupMPpage[offset=1pt] //(http://www.tug.org/pipermail/pdftex/2001-March/000429.html). I tried, but did not work however... Any idea how I should do? Find below minimal example, that does not work on my computer when compiling with context... Thanks!! Matthieu \starttext \setupMPpage[offset=1pt] \switchtobodyfont[10pt] % Beginning MetaPost graphic \startMPpage label.top(btex 1.4 etex scaled 1.00, (10, 10)); label.top(btex $\sigma_t$ etex scaled 1.00, (0, 10)); label.top(btex $\displaystyle \frac{\sigma_t}{a}$ etex scaled 1.00, (1, 1)); \stopMPpage \stoptext

strange error on ntgmaps style
by Hans van der Meer 26 Apr '11

26 Apr '11

I get a strange error when using the dutch NTG-MAPS style I acquired from Taco, quite some time ago taking into account the fast pace of development in ConTeXt ;-) The error location in the log seems to be not directly related to the culprit, because deleting some lines shifts the given linenumber that number of lines down. If I comment out the maps style and its macros: \usemodule[map-se]\enablemode[nosubsub] \startArticle[.....] \startAbstract ... \stopAbstract \startKeywords ... \stopKeywords \stopArticle then typesetting does not give the error. The error message is: 122 \placefigure[][fig:cdtypes]{Cover types for CD}{% <inserted text> ...ttwo ] \par \usemathcollection [eul] \par \stoptypescript \dodousetypescript ...e \the \documenttypescripts \firsttypescriptpassfalse ... \dotripleemptythreespaced #1#2#3->#1[{#2}][{#3}][] <to be read again> \par ConTeXt ver: 2011.03.28 01:03 MKIV fmt: 2011.3.28 int: english/english I must mention the fact that formerly this did work (the article even being published in the NTG-MAPS). Is there a new version of the NTG-MAPS module to try? Hans van der Meer

Grid typesetting and inline math
by Christoph Redecker 26 Apr '11

26 Apr '11

Hello, I'm struggling with the grid. I've stepped from LaTeX to luaLaTeX for a simpler font selection, and from luaLaTeX to ConTeXt for getting a usable grid (because I was told that it supports typesetting on a grid). Now that I got font selection working as desired in ConTeXt, the grid is driving me crazy. I'm trying to use the grid as described in details.pdf, and I want halfline spacing around formulas in text, because a full line is definitely too much. This is what I'm compiling: \setupbodyfont[10pt,serif] % should be lm? \setuplayout[grid=yes] \setuptextformulas[step=halfline] \starttext \showgrid Testing inline math: \gform{x_2 = \frac{a}{b}}. The following line should be seperated from this one by half a line, but it isn't. Testing inline math: \gform[-]{x_2 = \frac{a}{b}}. The following line should be seperated from this one by half a line, but it isn't. \stoptext Both paragraphs look identical, the second line is too far away from the first one. What's wrong with my code? Also, how can I manually depart from the grid, e.g. for block quotes? Regards, Christoph

\setuppublications problem
by Jean Magnan de Bornier 26 Apr '11

26 Apr '11

Hi all, Using the last mkiv from the minimals, \setuppublications seems out of order. If I write: .................................. \setupbibtex [database=/home/jean/biblio] \setuppublications[alternative=apa] \starttext {\bf Bibliography} \nocite[foo, bla, blu] \placepublications \stoptext ................................... the pub list is empty. But if comment out this line the bibliography is printed; it works also ok with \setuppublications[] -- Jean

Creating a PDF named destination
by Duncan Hothersall 26 Apr '11

26 Apr '11

Hello all, This seems to be a very obvious FAQ but I can't find an answer anywhere. How can one create a named destination in an output PDF file such that an HTML link to <filename>.pdf#nameddest=<name> will work? I'm using Mk II in case that is relevant. I kinda assumed that a section title with an ID would automatically create a named destination with the same ID, but that doesn't appear to be the case. So given a file generated from \starttext \chapter[myid]{My chapter} Blah blah. \section[myotherid]{My section} Blah blah. \stoptext I'd like to be able to link from an HTML file to the named destinations myid and myotherid using the #nameddest URL construct above. Hope it makes sense and thanks for any help. Duncan

\type macro weird?
by Hans van der Meer 25 Apr '11

25 Apr '11

This works fine: \starttext Here a type macro <\type{\abc}> \stoptext This also: \starttext \placetable{table \type{abc} title}{abc} \stoptext This too: \starttext \placetable{table \type{\blank} title}{abc} \stoptext But this gives an error (mind the \ before abc). \starttext \placetable{table \type{\abc} title}{abc} \stoptext Do I misinterprete something here? I just wanted to typeset "\abc" in the type-font. Why is the very first \abc treated as text to typeset but requires the placetable argument that it is an existing macro? Or isn't this the intended behaviour? Hans van der Meer Error log: system > tex > error on line 3 in file test.tex: Undefined control sequence ... 1 \starttext 2 %Here a type macro <\type{\abc}> 3 >> \placetable{table \type{\abc} title}{abc} 4 \stoptext 5 \@@kjtabletitle ->table \type {\abc } title \doif #1#2->\edef \!!stringa {#1 }\edef \!!stringb {#2}\ifx \!!stringa \!!str... \dostructurecountercomponent ...\c!title }\v!none {\setfalse \hasstructureco... \docompletefloat ...c!title ={#4},\c!bookmark =][] \globallet \previousfloatn... <argument> ...{table \type {\abc } title}\nextbox \else \docompletefloat {ta... \secondoftwoarguments #1#2->#2 ... l.3 \placetable{table \type{\abc} title}{abc}
