ini -> C -> lua -> context -> pdf
by Peter Münster 22 Feb '08

22 Feb '08

Hello, I have to convert an "ini"-file to pdf. On the one hand, it's easy for me to do most things in C, on the other hand, I would like to enlarge my experience with lua and ConTeXt. So here my question to the experts: what languages would you use for the different tasks? In fact, I believe lua could do a good job for some tasks, but I'm not really sure. Here the details: Example "ini"-file with 2 entries (the real file has about 200 entries): [temp_room] comment = the room temperature in °C description = This value must be sent at least once per 15 minutes, \ but only if a local sensor is connected to the device. size = 16 channel = master fb = RTS dpt = 2.009 dir = o [power] comment = the actual power available in % description = This value is only used to calculate the energy \ consumption. size = 8 channel = slave fb = HVA dpt = 4.307 dir = i The tasks: - put theses entries into a structured table (easy to do in C and the iniparser library http://ndevilla.free.fr/iniparser/ but it could be nice to do it in lua) - sorting (several PDF-documents with different sorting: by name, size, channel or other values) - filtering, for example _ must be converted to \_ and % to \% (same question: C, lua or ConTeXt) - formatting with nice layout (certainly with ConTeXt) For example, the first entry could become: 1.) temp_room, the room temperature in °C ----------------------------------------- ______________________________________________________________________ | Master | RTS | Output with datapoint type 2.009 (16 bits) | |___________|_________|______________________________________________| This value must be sent at least once per 15 minutes, but only if a local sensor is connected to the device. (Until now, I've coded just one line of lua-code in my life...) Perhaps, with your help, the subject line could become: ini -> MKIV -> pdf Thanks in advance for any hints and encouragements! Cheers, Peter -- http://pmrb.free.fr/contact/

Heros (font)
by Michal Kvasnička 22 Feb '08

22 Feb '08

Hallo to you all. I'd like to use TeXGyre fonts termes and heros. I tried something like this: \usetypescriptfile[type-gyr] \definetypeface[termes][rm][serif][termes][default][encoding=ec] \definetypeface[termes][ss][sans][heros][default][encoding=ec] \definetypeface[termes][mm][math][times][default][] \setupbodyfont[termes,18pt] However, I found that fonts as TeXGyreHeros-Regular are not defined. So I added this: \loadmapfile[qhv-ec.map] \definefontsynonym [TeXGyreHeros-Regular][ec-qhvr][encoding=ec] \definefontsynonym [TeXGyreHeros-Italic][ec-qhvri][encoding=ec] \definefontsynonym [TeXGyreHeros-Bold] [ec-qhvb][encoding=ec] \definefontsynonym [TeXGyreHeros-BoldItalic] [ec-qhvbi][encoding=ec] Now it works---I get not run-time error, and I can see some Helvetica-like fonts (though I'm not sure that the Czech accents are all right). However, the AdobeReader says I use some Quasi-Swiss fonts, not TeXGyreHeros as I would expect. What's wrong? I've got ConTeXt ver: 2008.01.28 21:28 MKII. I installed manually TeXGyre fonts from the TeXGyre page some days ago. Many thanks for your kind help. And greeting to all of you. Michal

cite-specific question
by Trond Lossius 22 Feb '08

22 Feb '08

Hi, in LaTeX I've been able to do cites in a number of different ways, depending on what's needed. In ConTeXt I've figured out how to do \cite[key] Full author list and year (Watson and Crick 1953) as well as how to add reference to the page number using \cite[extras={, page 5}[key]. But I'm wondering if it is possible to get something similar to \citeN{key}, \citeNP{key}, etc. in LaTeX: \cite{key} Full author list and year (Watson and Crick 1953) \citeA{key} Full author list (Watson and Crick) \citeN{key} Full author list and year. Watson and Crick (1953) \citeyear{key} Cite year only (1953) All the above have an NP variant without parentheses; Ex. \citeNP. Thanks, Trond

[OT] suggestion for books on (typo)graphic design
by Andrea Valle 21 Feb '08

21 Feb '08

Hi to all and sorry for the OT, but here on the list there are some of the most competent people I know on the topic. I will start a course on graphic communication. The students are ground-zero programmers, all on mac, so I would like to use Nodebox (http://nodebox.net/) (Unluckily no time/space to introduce ConTeXt). I will focus on data visualization, so I was considering to adopt Tufte's classic The Visual Display etc. I've still not read Envisioning Information and Visual Explanations. Any ideas? I will have also to introduce basic elements of graphic communication (e.g. fonts, page composition, color usage etc). Suggestions? Many thanks!

Strange behavior of framed text
by Aditya Mahajan 21 Feb '08

21 Feb '08

Hi, In core-rul.tex we have %D We define the general (and original) case by just saying: \defineframedtext[\v!framedtext] This gives strange user behavior. Consider the following \defineframedtext[test][width=broad] \showframe \starttext \starttest \input tufte \stoptest \startframedtext[test] \input tufte \stopframedtext \stoptext The two framedtext have different widths. Why not say \def\startframedtext {\dosingleempty\dostartframedtext} \def\stopframedtext{\dostopframedtext} Aditya

Adobe Reader, PNG transparency and colors
by Michal Kvasnička 21 Feb '08

21 Feb '08

Hallo you all. I found a strange problem. I create my slides with ConTeXt. Everything was all right before I included pictures in PNG with transparent background. Adobe Reader 8.1.2 under Linux (at least this one) changes colors on every page where such a PNG is included. Xpdf shows it all right. I wonder what could be the reason, and how to solve it. Can you hint me? You can see the behavior here: http://www.econ.muni.cz/~qasar/vyuka/inst/inst-slide01.pdf Notice difference in colors between the 2nd and 3rd page (the 3rd one includes PNG). PNG are created with Gimp. My ConTeXt is ver: 2008.01.28 21:28 MKII pdfTeX is 3.141592-1.40.3 (Web2C 7.5.6) TeXExec is version 6.2.0 All under openSuSE Linux 10.3. When I start TeXExec, I got this warning: /usr/bin/texmfstart:1838: warning: Insecure world writable dir /home/qasar/bin in PATH, mode 040777 /usr/share/texmf/scripts/context/ruby/base/system.rb:16: warning: Insecure world writable dir /home/qasar/bin in PATH, mode 040777 But I guess it has nothing to do with the color problem. Many greetings to all of you, and thanks to those answering me. ;-) Have a nice day. M.K.

crash with \attributedbox

Hi, I updated my binaries today (minimals) and got some crashes using luatex v0.22. No probs with the prior version. I was able to make a minimal example by simplifying my original code.

As it stands, it seems safe to > say that, if colors don't work, then PGF is quite crippled in ConTeXt. No, the reason for the error is more subtle. PGF does try its best to work with ConTeXt colors. However, there is a difference between latex and context color usage, that gives rise to the error. The culprit in this case is: {$\displaystyle \tan \alpha \color{black}= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}$} Try this in a standalong context file (no pgf) and you will get an error. First you need to change \color{black} to \color[black]. Even then you will get an error. You need to use {$\displaystyle \tan \alpha {\color[black]= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}}$} (Notice the {...} around \color[black]). Then everything works fine. Here is a working example (latest pgf from cvs, but should also work with 1.18). \usemodule[tikz] \setupcolors[state=start] \starttext \starttikzpicture[scale=3] \clip (-2,-0.2) rectangle (2,0.8); \draw[step=.5cm,gray,very thin] (-1.4,-1.4) grid (1.4,1.4); \filldraw[fill=green!20,draw=green!50!black] (0,0) -- (3mm,0mm) arc (0:30:3mm) -- cycle; \draw[->] (-1.5,0) -- (1.5,0) coordinate (x axis); \draw[->] (0,-1.5) -- (0,1.5) coordinate (y axis); \draw (0,0) circle (1cm); \draw[very thick,red] (30:1cm) -- node[left=1pt,fill=white] {$\sin \alpha$} (30:1cm |- x axis); \draw[very thick,blue] (30:1cm |- x axis) -- node[below=2pt,fill=white] {$\cos \alpha$} (0,0); \draw[very thick,orange] (1,0) -- node [right=1pt,fill=white] {$\displaystyle \tan \alpha {\color[black]= \frac{{\color[red]\sin \alpha}}{{\color[blue]\cos \alpha}}}$} (intersection of 0,0--30:1cm and 1,0--1,1) coordinate (t); \draw (0,0) -- (t); \foreach \x/\xtext in {-1, -0.5/-\frac{1}{2}, 1} \draw (\x cm,1pt) -- (\x cm,-1pt) node[anchor=north,fill=white] {$\xtext$}; \foreach \y/\ytext in {-1, -0.5/-\frac{1}{2}, 0.5/\frac{1}{2}, 1} \draw (1pt,\y cm) -- (-1pt,\y cm) node[anchor=east,fill=white] {$\ytext$}; \stoptikzpicture \stoptext Aditya
