Hi, The example from http://wiki.contextgarden.net/m-database gives me an error. ! LuaTeX error ...t-beta/texmf-context/tex/context/base/m-database.lua:74: bad argument #2 to 'lpegmatch' (string expected, got nil) stack traceback: [C]: in function 'lpegmatch' ...t-beta/texmf-context/tex/context/base/m-database.lua:74: in function 'process' <main ctx instance>:1: in main chunk. \doprocessdatabase ...ameter \c!command \!!es , }} l.18 \stopMyTable I also, tried the first example of Mojca's CSV May Way (http://dl.contextgarden.net/myway/csv.pdf) which gives me: !

running headers on postponed makeup
by Philipp Gesang 20 Dec '10

20 Dec '10

Hi all, after discovering postponed insertions I encountered a problem when combining it with the makeup mechanism I am so fond of. ···8<···························································· \definemakeup[my] \setupmakeup[my][ headerstate=start, page=yes, ] \startbuffer[mkup] \startmymakeup \vfill\externalfigure[cow][width=\hsize]\vfill \stopmymakeup \stopbuffer \setuppagenumbering[alternative=doublesided,location=footer] \setupheadertexts [{\getmarking[section]}] [outer] [outer] [{\getmarking[section]}] \starttext \startpostponing[+2] \getbuffer[mkup] \stoppostponing \dorecurse{10}{\section{the Don spake} \input knuth } \stoptext ···8<···························································· Is there way to get the running header on the makeup page? Tweaking the “headerstate” does not seem to have an effect on this.

[achim@jander.de: Re: startcolumns: text runs into footer]

Hi all, I’m just forwarding this to the ml as I can’t help any further and I’d like to know the answer too. @Achim: have you tried locally chopping off a line from the text area with “\[start|stop]columns”? Something like this: ··8<····························································· \newdimen\Reducedtextheight \let\Reducedtextheight\makeupheight \advance\Reducedtextheight-\baselineskip \setuplayout[height=\Reducedtextheight] ··8<····························································· Not a clean solution, but it might still get you what you want.

mkiv: append to buffer
by Thomas Schmitz 20 Dec '10

20 Dec '10

Hi all, i guess this is easy, but I can't find an example to help me: I want to write a macro that will collect one of its arguments in a buffer and then collect the other argument in a buffer. Difficult to make a minimal example since I don't know how to do this, so here is some pseudo-code; this is what I want to achieve: \definebuffer[MyBuffer] \def\MyGreatMacro#1#2#3% {\item[#1] #2 \par \appendtobuffer{MyBuffer}{\in[#1] #3}} \starttext \startitemize \MyGreatMacro{1}{aa}{AA} \MyGreatMacro{2}{bb}{BB} \stopitemize \page \getbuffer[MyBuffer] \resetbuffer[MyBuffer] % so I can reuse the buffer \stoptext What I want to do with this is typeset exercises for my students, with an itemization for problems and solutions which use the same numbering. In real life, this will involve xml, but I will try and figure that out myself once I know how to use buffers... It looks like buffers.collectcontent should be able to do this, but I can't figure out how to use it. Any pointers? Thanks a lot! All best Thomas

startcolumns: text runs into footer
by Achim Jander 19 Dec '10

19 Dec '10

Hi at all, now I've run into the next problem: Trying to set text in 2 columns. Even in the simples case: \showframe \starttext \startcolumns \dorecurse{20}{\input knuth} \stopcolumns \stoptext The text goes ca 1 line into the footer-region. I played around with various settings (blank, align=yes, setupwhitespace etc), but can not figure out how to keep the text in the main area only. Another related question: for which purpose is the columns setting in setuplayout? It doesnt seem to affect the output? And still another question: how can i fine-control the amount of whitespace, especially the strechability and shrinkability? is \setupwhitespace[2pt plus 2pt minus 2pt] the right way? And how is the equivalent syntax for \blank? Thanks, Achim

Minimal spacing between sentences
by Florian Wobbe 19 Dec '10

19 Dec '10

Hi, how can I increase the minimal spacing between sentences? \setfrenchspacing seems to work only in a justified line: \starttext \setfrenchspacing{15000} This is a short sentence. It is not followed by a big space. Here are some justified lines which have big spaces: \input tufte \stoptext Thanks, Florian

ascii ribbon
by Philipp A. 19 Dec '10

hi, do you really support this obsolete statement? if so: why? - html mail is supported by every mail reader nowadays, and nowhere near broken - semantic html is way better for blind people than plain text, since it is, well, semantically structured. something enclosed in em-tags will e.g. pronounced in a accentuated voice by the screen reader. - e mail sizes are no problem with today's hd capacity - every proper mail reader does block pics from foreign sources for privacy reasons essentially: this was true, and isn't anymore. if you think http://www.xkcd.com/386 , you are right, i'm like that :) cu in the context forum, philipp

problem with setupwhitespace
by Achim Jander 19 Dec '10

19 Dec '10

Hello, I am trying to setup a layout for a book. Its very simple, consisting only of paragraphs. Regularly, there should be no space between them, but to force the pages getting filled there may be a small space. I cannot figure out how to set it up. In the mailing list I found the sample \setupwhitespace[3pt plus 2pt minus 1pt] but in fact, that seems to have no effect, the page ist not filled. The Reference-Manual doesnt mention this form, but states that there is some stretchability. How can I define the stretchability? My simple Example: \definepapersize [NomosLexSozA] [width=125mm, height=210mm] \setuppapersize [NomosLexSozA] [A4] \setuplayout[ header=0cm,footer=0cm, backspace=2.54cm,topspace=1.5cm, width=middle,height=middle, location=middle,marking=on,] \showframe \setuppagenumbering[alternative=doublesided] \setupbodyfont[rm,7.5pt,serif] \setupinterlinespace[line=8pt] \setupbodyfontenvironment[default][em=italic] \setupwhitespace[3pt plus 2pt minus 1pt] %\setupwhitespace[line] %\setupwhitespace[medium] %\setupwhitespace[big] \setuptolerance[horizontal, verytolerant, stretch] \setuptolerance[vertical, verystrict] \starttext \dorecurse{40} {\input knuth} \stoptext with big or medium, it seems to work, but that is to much whitespace for my layout? Can anyone give me a hint? Thanks, Achim

Horizontal space in math subscript generated by Lua
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Dec '10

18 Dec '10

Hello, I encountered a strange effect. Let's have a code that generates the same math, firstly by Ctx and secondly by Lua: --- \starttext \startformula M_{t,WnT} = 1000 \stopformula \startluacode context.startformula() context("M_{t,WnT} = 1000") context.stopformula() \stopluacode \stoptext --- You can see the result - the space between "W" and "n" in lower index is smaller when generated (natively) by Ctx than that in math generated by Lua. (The latter case may affect a bit "disturbingly" to the reader.) It seems also that space between (subscript) "T" and "=" varies. So why these differences? How to avoid the extra-space when Lua generates math subscript? Best regards, Lukas -- Ing. Lukáš Procházka [mailto:LPr@pontex.cz] Pontex s. r. o.
