color expansion at runtime
by Peter Rolf 17 Dec '07

17 Dec '07

Hi, I desperately need runtime defined colors (state dependent) for my macros. The macros are used with different graphic styles, which is the reason why I want to avoid any style dependent part inside them. To give you an example. I need something like this \color[{\StateDependentColor[stateA=green,stateC=blue,whatever=yellow,...]}] If flag 'stateA' is true at runtime, then color 'green' is used (and so on; order is significant). I have written such a macro, but sadly it crashes when used inside \color or \definecolor. Tried to debug it, but this is my first experience with the trace commands (probably not the best example to start with). Sigh, still so much to learn.. :) Any hints are welcome. Regards, Peter \setuppagenumber[state=stop] \setupcolors[state=start] \definecolor[colorA] [red] \definecolor[colorB] [green] \definecolor[colorC] [blue] \newconditional\CondA \newconditional\CondB \newconditional\CondC \unprotect \def\GetStateDependentColor[#1]% {\bgroup \rawgetparameters[SDC@][A=,B=,C=,#1]% \def\MYdocommand##1% {\doifdefined{Cond##1} % conditional is known.. {\expandafter\ifconditional\csname Cond##1\endcsname % ..AND true.. \edef\CurrentColor{\csname SDC@##1\endcsname}\else \def\CurrentColor{}\fi \doifelsenothing\CurrentColor % ..AND a color is assigned \donefalse\donetrue}% \ifdone\CurrentColor\expandafter\quitcommalist\fi}% \processcommacommand[A,B,C]\MYdocommand % raw version does not work! why? \egroup} \protect \starttext \setfalse\CondA \settrue\CondB \settrue\CondC \tracingonline=1 %\tracingall=1 %\tracingmacros=1 %\tracingcommands=2 color is -\GetStateDependentColor[A=colorA,C=colorC]- % works so far %\tracingmacros=0 %\tracingall=0 % crashes %\tracingall=1 %\tracingmacros=1 %\tracingcommands=2 %\definecolor[testcolor][{\GetStateDependentColor[A=colorA,C=colorC]}] %\color[testcolor] %\color[{\GetStateDependentColor[A=colorA,C=colorC]}] %\expandafter\color\expandafter[\expandafter{\GetStateDependentColor[A=colorA,C=colorC]}] %\tracingall=0 TEST \stoptext

chapter without number but in table of contents
by Patrick Gundlach 17 Dec '07

17 Dec '07

Hi, I know that this must be an faq and I seem to have lost my context knowledge: I'd like to get an unnumbered chapter, but it should appear in the table of contents. This is what I've tried so far: -------------- \completecontent [alternative=c] \definehead[mychapter][chapter] \setuphead [mychapter][number=no] \mychapter [sec:somechapter]{Some Chapter Without A Number} \input tufte ---------------- The chapter heading looks fine, but the entry is missing from the table of contents. Any idea? Patrick -- ConTeXt wiki and more: http://contextgarden.net

Customising Table of Contents
by Saji N. Hameed 17 Dec '07

17 Dec '07

Dear All, Sorry this may be a trivial issue. The document I am preparing has two parts - a main one and appendices. In the table of contents (toc), I want to list chapter names and section names for the main part. However for the appendices, I want to list only the chapter names. I would appreciate any advice on how to achieve this. The toc should look like 1. Chapter 1 1.1 section 1 2. Chapter 2 2.1 section 2.2 section A. Appendix 1 B. Appendix 2 C. Appendix 3 Thanks in advance, saji -- Saji N.

HTML to Context with Regular Expressoin
by Jan Kraljič 17 Dec '07

17 Dec '07

Hello, I'm trying to create WYSWYG editor for Context. I started with FCKeditor which is great HTML WYSWYG. My idea was to use html code generated by FCKeditor than to use regular expression so ContexT. Thats giving me headache. In contextgarden I found some solution for changing HTM to ConTeXt but i didn't find any that would use regular expression. Now i wonder if there is any list of expressions for replacing HTML with ConTeXt or should I start somewhere on contextgarden and hope for help to complete. I believe that such replacement table can help few to thinking about using ConTeXt. Best regards, Jan -- Macs are for those who don't want to know why their computer works.

filepath on format generation
by Hans van der Meer 17 Dec '07

17 Dec '07

I migrated my texlive2007 tree to a new disk and now I encounter permission difficulties on context format generation. Calling the bashrc alias: alias formats='texmfstart texexec --make en; texmfstart texexec --make --alone metafun After the normal (error) messages about ls-R updating I get a permission error: TeXExec | using search method 'kpsewhich' TeXExec | updating file database mktexlsr: Updating /Users/hans/Tex/texmf-private/ls-R... mktexlsr: /usr/local/texlive/2007/texmf: directory not writable. Skipping... <these are expected, no access for me to these directories> mktexlsr: Done. TeXExec | using tex engine pdftex TeXExec | using tex format path ./pdftex TeXExec | unable to make format due to lack of permissions and on calling the following alias: alias texversion='texmfstart texexec.pl --version; rm mpgraph.mp texvers-mpgraph.mp' I get: fmtutil: format directory `/web2c' does not exist. kpathsea: Running mktexfmt context.fmt fmtutil: format directory `/web2c' does not exist. In my .bashrc I have: # TeX variables CONTEXT_RUBY=/usr/local/texlive/texmf-local/scripts/context/ruby TEX_HOME=/usr/local/texlive/2007 TEXMFCACHE=/Users/hans/Temp OSFONTDIR=/Library/Fonts TEXMFCNF=/usr/local/texlive/texmf-local/web2c TEXMF="{/Users/hans/Tex/texmf-private,/usr/local/texlive/texmf- context,/usr/local/texlive/texmf-local,/usr/local/texlive/2007/texmf,/ usr/local/texlive/2007/texmf,/usr/local/texlive/2007/texmf-config,/usr/ local/texlive/2007/texmf-dist,/usr/local/texlive/2007/texmf-doc,/usr/ local/texlive/2007/texmf-var}" TEXFORMATS=/usr/local/texlive/2007/texmf-config/web2c nor did work: TEXFORMATS=/Users/hans/.texlive2007/texmf-var/web2c/pdftex The idea is to have the formats locally under .texlive2007 in my home directory. Can someone enlighten me where the base of respectively ./pdftex and / web2c is supposed to be? I thought I did set my environment variables just as I did previously, when it worked. Why suddenly these apparently incomplete paths? I MUST have some pathvariable WRONG, but which one is it? Hans van der Meer

absolute positioning?
by Patrick Gundlach 15 Dec '07

15 Dec '07

Hello! What is the current most contextish way for absolute positioning of text (still using MK II)? I have to create a title page for a document where several frameless boxes of text have to be placed on the page. Is this still the layer mechanism? I mean, ConTeXt evolves so quickly, being absent for one real year means being absent for about 10 ConTeXt-years. Patrick -- ConTeXt wiki and more: http://contextgarden.net

beta
by Hans Hagen 14 Dec '07

14 Dec '07

Hi, I uploaded a new (mkiv) beta. The biggest change is that there are some optimizations in the cached mkiv font tables which should lead to (1) faster loading and (2) a smaller memory footprint. I may have messed some things in the process, so testing is appreciated.
