Writing a ConTeXt module for R
by Johan Sandblom 07 Jun '06

07 Jun '06

Since I sometimes use the open-source statistics environment R (http://www.r-project.org) as well as ConTeXt, I thought a module that could typeset R code as well as evaluate it on the fly would be useful. Borrowing largely without understanding but lots of trial and eror from m-gnustep.tex, I came up with the attached. Limited testing indicates it works, but at least one problem is apparent: the R code snippets have one unnecessary line break to start them and two after the end. How can I fix that? Of course, any other suggestions are also welcome. A recent R needs to be in the path, but given that, it seems to work on Windows XP as well as Linux. Regards, Johan PS Emacs users may appreciate the following to get r-mode where appropriate: (require 'mmm-mode) (setq mmm-global-mode 'maybe) (setq mmm-submode-decoration-level 2) (mmm-add-group 'context-plus '((context-MP :submode metapost-mode :face mmm-code-submode-face :front ".*\\\\start\\w*MP\\w*\${\\w*}\\|\\[\\w*\\]\\|\$\\W" :back ".*\\\\stop\\w*MP") (context-R :submode r-mode :face mmm-comment-submode-face :front ".*\\\\startR.*\\W" :back ".*\\\\stopR.*"))) (add-to-list 'mmm-mode-ext-classes-alist '(context-mode nil context-plus)) -- Johan Sandblom N8, MRC, Karolinska sjh t +46851776108 17176 Stockholm m +46735521477 Sweden "What is wanted is not the will to believe, but the will to find out, which is the exact opposite" - Bertrand Russell

XeTeX working on Windows as well !!!

Hello all, I have no idea when this came out, but it works like a charm! http://www.fsci.fuk.kindai.ac.jp/kakuto/win32-ptex/web2c75-e.html I didn't try out ConTeXt + XeTeX yet (I only played with plain XeTeX a bit), but the fact that the distribution includes the latest ConTeXt (even more recent that the one on the pragma-ade.com, namely the version of 30th May :) and that it includes texmfstart.exe makes me feel that I'll love that Japanese TeX distribution!

texsync --delete
by Peter Münster 06 Jun '06

Hello Hans, could you please add the option "--delete" to @@rsync in texsync.rb? I've just realised, that cont-lmt.zip no more exists, but texsync never deleted it on my hard-disk. Cheers, Peter -- http://pmrb.free.fr/contact/

MPinclusions strangeness with labels
by Jean Magnan de Bornier 06 Jun '06

06 Jun '06

Hi all, I found something strange with a metapost file where I want to store various definitions for reuse in several tex files; here are example files: .......inc.mp............... numeric u; u=.8cm; path AX; AX = (10u,0) -- (0,0) -- (0,10u); picture cax; cax = thelabel(textext("Costs, prices") rotated 90,(-.3u,8u)); ............................ .......inc.tex.............. \setupoutput[pdftex] \startMPinclusions \input inc \stopMPinclusions \starttext \startuseMPgraphic{toto} drawdblarrow AX; % label.rt(textext("$3x^2+\pi$"), (5u,6u)); draw cax; \stopuseMPgraphic \placefigure[left]{bla.bla}{\useMPgraphic{toto}} \input dawkins \stoptext ............................ Now what happens? The label in the mp file "Costs, prices" is replaced by "unknown" in the pdf. But if I add a label in the startuseMPgraphic environment, (decommenting line 3 in it), then both labels appear!! I tried several other files, it seems to happen every time. Anything I'm doing wrong? tia -- Jean

Generating Module documentation
by Aditya Mahajan 06 Jun '06

06 Jun '06

Hi, How does one generate module documentation? I copied mult-ini.tex to a temp directory and did texmfstart texexec --modules mult-ini.tex but did not get any output. Looking into texexec.rb, I tried to recreate a temp file to generate the documentation. The following \usemodule[abr-01,mod-01] \def\ModuleNumber{1} \starttext \readlocfile{mult-ini.tex}{}{} \stoptext gives This is pdfeTeX, Version 3.141592-1.30.3-2.2 (Web2c 7.5.5) (format=cont-en 2006.5.31) 5 JUN 2006 21:13 entering extended mode \write18 enabled.

Grouping with \dosingleempty

Hi, I am confused why the following definition does not work as expected. \def\PM{\dosingleempty\doPM} \def\doPM[#1]{\iffirstargument P_{M_{#1}} \else P_{M_t}\fi} \starttext Why is $\widetilde \PM[T]$ not the same as $\widetilde P_{M_T}$ \stoptext Can I change the definition so that $\widetilede \PM$ is same as $\widetilde P_{M_t}$ and $\widetilede \PM[T]$ is same as $\widetilde P_{M_T}$ Thanks, Aditya

I-installer tex install --- no ligatures
by David Arnold 06 Jun '06

06 Jun '06

All, I have a colleague who installed tex on his Mac using Gerben's i- installer, installing the files in the order defined on: http://www.uoregon.edu/~koch/texshop/installing.html He did not install CB Greek, MusixTeX, or XeTeX, but all the other files on this page, he installed in the order given. Ligatures are missing. Can you help me advise my colleague? Anyone else have any font problems with the latest install of Getben's tex?

Referencing examples with identical labels in different sections
by David Arnold 06 Jun '06

06 Jun '06

All, I have in my environment file: \defineenumeration [example] [location=serried, width=broad, text={\color[heavygreen]\bgroup\bold{Example}}, stopper={.\egroup}, style=slanted, inbetween=\blank, after=\blank] Now, I have a chapter with four sections. What can I do so that \startexample[exmpl:one] ... \stopexample in section one will be differentiated from \startexample[exmpl:one] ... \stopexample in section two? That is, a label in section two that refers to the exmpl:one will reference the exmpl:one in section one.

a few questions on Arabtex
by R. Ermers 05 Jun '06

05 Jun '06

Dear friends, I have been trying again to get Arabtex running. I got the most recent version of apatch.sty etc. There are some problems. Question 1. context gets stuck When using Arabtex with Context (which I prefer now), the run stops on a command in apatch, \hc, referring to hepatch. Arabtex works normally with Latex, though. I already asked Prof. Lagally, but he wrote me that he believes the bug is probably related to Context. Question 2. question mark The Arabic question mark does not work: \<zayd?> results in an error, I am not sure, but I believe the question mark is remapped to something else (perhaps something unicode-ish) which Arabtex cannot handle. Does anybody have a clue? Regards, Robert Ermers %%%%%%% Question 1 (17.09.2001))) (D:\tex\localtexmf\tex\arabtex\./apatch.sty ! Undefined control sequence. l.190 \hc % default Hebrew font ?
