parsing custom syntax in lua
by Vianney le Clément 31 Aug '10

31 Aug '10

Hello, What is the best way to pass verbatim text to lua for processing? I would like to write a lua parser for non-TeX text with a custom syntax (could be something like Markdown for instance). The interface would be \startMyFormat % custom syntax % \stopMyFormat \processMyFormatfile[external file.custom] % alternative The text between \startMyFormat and \stopMyFormat or the text read from the external file should be passed as one utf8-encoded string to a lua function. Any ideas on how to write these macros? On a side note, does anyone know of a quick way to strip diacritical marks from utf8-encoded strings in lua (i.e., transform them to pure ascii)? Thanks, Vianney

[PATCH] small corrections for the ConTeXt-correspondence manual
by Paul Menzel 31 Aug '10

31 Aug '10

Dear ConTeXt folks, this is my first post and I am looking forward to get more acquainted with ConTeXt. I read the ConTeXt-correspondence manual (module letter [1]) and attached you will find some formal fixes for the source files gotten from [2]. If I should sent each patch as a separate message, please tell me. I was not able to get a PDF created with my Debian Sid/unstable system, so I could not test my changes. $ texexec correspondence.tex […] ! Undefined control sequence. l.139 \doifolderversionelse \contextversion{\currentmoduleparameter\c!context... I hope this is the right way to contact the authors and to submit the patches. If not, please tell me the preferred way. As a last remark, I would really love to see the sources and documentation of modules under SCM so contributing would be easier. There are some free services for free software projects as for example Gitorious [3]. Thanks, Paul [1] http://modules.contextgarden.net/letter [2] ftp://tug.ctan.org/pub/tex-archive/macros/context/contrib/context-letter [3] http://www.gitorious.org/

Filling boxes
by Cecil Westerhof 31 Aug '10

31 Aug '10

I have (a long time ago) made the following .tex file: % christmasTree.tex: creates a to-do Christmas tree % Copyright 2009 Cecil Westerhof, Decebal Computing % You are free to use this code when you keep my copyright % This file should be processed with ConTeXt (texexec file) \usemodule[defaults] \setupoutput[pdf] \setuplayout[header=0cm, footer=0.25cm] \defineframed [action][width=5cm, height=3cm, offset=none] \defineframed [base] [width=3cm, height=2cm, offset=none, topframe=off] \starttext \setupheader[state=high] \setupfootertexts[\hfill {\switchtobodyfont[6pt]\copyright Decebal Computing, http://www.decebal.nl} \hfill][] [][] \setupalign[middle]\offinterlineskip {\bold\switchtobodyfont[32pt]De taken kerstboom\switchtobodyfont[16pt]\blank} \noindent\action[bottomframe=off]{} \noindent\action[bottomframe=off, rightframe=off]{}% \action[bottomframe=off]{} \noindent\dorecurse{2}{% \action[rightframe=off]{}% }% \action{} \dorecurse{7}{ \noindent \base{} } \stoptext It makes a 'Christmas tree' made of boxes. What I would like is to put some text, which are given as parameters, into the 13 boxes. But when a text does not fit into it's box, I do not want the PDF to be generated and receive an error code.

framed text over multiple pages
by Mojca Miklavec 30 Aug '10

30 Aug '10

Dear list, I'm trying to find the command (in manual, wiki or mailing list) that enables using background behind text spanning over multiple pages. At the moment I have \startframedtext [width=\textwidth, background=color, backgroundcolor=mycolor1, frame=off, leftframe=on, framecolor=mycolor2] but I remember that there used to be a command that allowed doing the same, but spanning the text over multiple pages. I would be grateful for any hint/pointer to the manual. I've found a document that does underlining of words in paragraphs, but this seems like an easier problem anyway. Thank you very much, Mojca

fixed columns height
by Jano Kula 30 Aug '10

30 Aug '10

Hello, looking for the multicolums of fixed height I've found the solution from Wolfgang [1], which doesn't work with latest beta (mkiv): \usemodule[streams] \definestreamlayer[test][method=overlay] \setupbackgrounds[page][background=test] \starttext \startstreamlayer[test] \startcolumns \input knuth \stopcolumns \stopstreamlayer \setlayer[test][x=5cm,y=10cm]{\placestreamlayer[test]} \stoptext Here is the scenario: tree columns of fixed height should be placed at the precise place (end of the page, so they can also float there). It is necessary to measure their natural height, also, to check if all the material fits in the the specified height or find some other way to check if the material is lost or not. Do you have any hints? Thanks, Jano [1] http://thread.gmane.org/gmane.comp.tex.context/55324/focus=55433

startenumerate in romans a la LaTeX
by Xan xan 30 Aug '10

30 Aug '10

Hi, I just want to simulate the behaviour of \usepackage{enumerate} ... \begin{enumerate}[(i)] \item \end{enumerate} in ConTeXt. That is: - items in (i), (ii), .... - right indentation of items: in context items start at the same point. In LaTeX is the item text itself who starts at the same point, not the romans. I try: \defineenumeration [mylema] [text={Lemma}, % Què es mostra before={\blank[big]}, % abans de lema, un bigskip after={\blank[big]}, % després de lema, un bigskip headstyle=bold, % Negreta per la capçaleras %between=\blank, % Entre Lemmes una línia en blanc titledistance=.5em, % espai entre número i parèntesis. textdistance=.5em, % espai entre ) i text stopper={.\space}, % Com acaba. Després de parèntesis un '.' location=serried, width=fit, % que ocupi tot l'espai style=italic, % estil del text title=yes, % si puc posar o no arguments opcionals titlestyle=bf, % estil del títol way=bytext, % enumerar en tot el document conversion=numbers,indenting=yes] % enumera amb arabic %enumera els lemes per seccion [...] \startmylema Let $G$ be a group with a finite presentation ${\cal P} = \langle X \mid R \rangle$. Then for all null-homotopic words $u, v$ in ${\cal P}$, \setupitems[align=right] \startitemize[r][left=(,right=),stopper=] \item $\text{area}(u \cdot w) = \text{area} (w \cdot u)$ \item $\text{area}(wuw^{-1}) = \text{area}(w)$ \item $\text{area}(u \cdot w) \leq \text{area}(u) + \text{area}(w)$ \item $\text{area}(u) = \text{area}(u^{-1})$ \stopitemize \stopmylema but the numbers are left-aligned and they bit the text. Can anyone help me? Thanks, Xan. PS: I have a new email address. The old has problems with sending emails.
