Question about definition of \frac
by Aditya Mahajan 23 Apr '07

23 Apr '07

In core-mat.tex \frac is defined as \def\dofrac#1#2#3{\relax\mathematics{{{#1{#2}}\over{#1{#3}}}}} \unexpanded\def\frac {\dofrac\mathstyle} Shouldn't that be \def\dofrac#1#2#3{\relax\mathematics{{\begingroup#1{#2}\endgroup\over#1{#3}}}} Basically, \begingroup ... endgroup instead of bgroup ... egroup generated by the braces. Compare the definition of \frac in core-mat with the definition of genfrac in m-newmat. I am not sure whether this really creates a difference or not, but generally most math definition try to avoid creating an extra group. Even LaTeX defines \frac as \def\frac#1#2{{\begingroup#1\endgroup\over#2}} So, should the definition of \dofrac be changed? Aditya

texlive 2007-2
by Norbert Preining 12 Apr '07

12 Apr '07

Hi all! I have uploaded texlive 2007-2 packages to the tug server. I have done the usual test runs (installing/removing etc), and have the packages running on my laptop and various documents processed fine. I will wait another day (ie till tomorrow evening) until uploading the whole bunch to Debian/unstable. If someone wants to test it, please give it a try. deb(-src) http://www.tug.org/texlive/Debian/ tl2007/ Thanks a lot and all the best Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Università di Siena Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- HAGNABY (n.)

Footer for ntg-context mailing list, to encourage feedback
by Mojca Miklavec 02 Apr '07

02 Apr '07

Hello, As a (delayed) part of my duty I'm now writing the report about the "Discussion on improving ConTeXt documentation". One of ideas was to add a short footer to each mail on the mailing list, which would encourage more people to reply after they get a solution to their feature request or a bug report (as opposed to the fact that many [sometimes including me] simply disappear after they get the answer and one never knows if they solved the problem or not). The following notices might be relevant to add to the default mail footer, but I'm afraid that the list is too long already. Any ideas/suggestions/comments? - Please "wikify" tricky parts and help us improve ConTeXt documentation: http://wiki.contextgarden.net/ http://texshow.contextgarden.net/ - Please test and provide feedback for any answers you get on the list: Did the solution work? Was the bug resolved? - Please help us collect new files for testing against bugs: http://wiki.contextgarden.net/Test - Confirmed and unresolved bugs are collected on https://foundry.supelec.fr/tracker/?atid=161&group_id=21 (Collecting test files should be simplified anyway; the last two items do not seem as relevant as the rest.)

Re: [dev-context] [NTG-context] Force all floats on opposite even pages

The requested layout is not all that bizarre, Wolfgang's code fairly small, and it could be a switchable thing, no need for it to be always on (i cannot say if it will/will not interfere with the normal page formatting) but it would be a shame to ignore this.

Re: [dev-context] [tex-live] Debian TeX -- new packages
by Sanjoy Mahajan 30 Mar '07

30 Mar '07

> We ask people using Debian to try these packages out, they survived > all my tests and quite a lot of documents I tried out, but YMMV. [What I describe below is not a Debian problem, but the proposed change would make the packages easier for Ubuntu users to use. I added dev-context to the CC: list since the pkg deps affect Ubuntu users -- e.g. me -- who use your excellent ConTeXt packages.] I'm using Ubuntu 6.10 (edgy) with all your tug.org stanzas. An "apt-get install texlive-base-bin" or "apt-get install context" fails when going from the TL2005 packages to the 2007 ones. The blocking package is texlive-base-bin: # apt-get install texlive-base-bin texlive-base-bin: Depends: libpng12-0 (>= 1.2.13-4) but 1.2.8rel-5.1ubuntu0.1 is to be installed Depends: libpoppler0c2 (>= 0.4.2) but it is not installable E: Broken packages I'll upgrade to the Ubuntu 7.04 beta, which will solve the libpng12-0 problem because Ubuntu 7.04 uses libpng 1.2.15. But libpoppler0c2 would still be missing. Here are the libpoppler pkgs in versions of Ubuntu: 5.04 (hoary) | libpoppler0-0.1.2 5.10 (breezy) | libpoppler0c2-0.4.2 6.04 (dapper) | libpoppler1-0.5.1 6.10 (edgy) | libpoppler1-0.5.4 7.04 (feisty) | libpoppler1-0.5.4 So, could you add libpoppler1 as an alternative libpoppler dependency? That should fix the installation. libpoppler1 is also in Debian (in experimental) so it should be a useful Debian change eventually. Then I can update to texlive 2007 and to the latest ConTeXt via apt-get. If that works, I'll update the ConTeXt wiki's installation instructions to say that Ubuntu users will have to upgrade to 7.04 to use your latest packages. Although, if it's possible to depend on an older libpng (on libpng12-0-1.2.8), then more Ubuntu users could upgrade. -Sanjoy `Not all those who wander are lost.' (J.R.R. Tolkien)

TeX on contextgarden disabled - \installprogram security
by Patrick Gundlach 29 Mar '07

29 Mar '07

Hi, I've just found out about \installprogram, that lets you run any command from TeX, bypassing the shellescape, openout and openin setting. This means that I have a serious security problem on contextgarden and therefore I have disabled all TeX typesetting. Any advise on how to disable this?

core-reg.tex possible patch needed
by Duncan Hothersall 29 Mar '07

29 Mar '07

Something I ran into in Epen which Taco helped me to fix. In cont-tmf.zip dated 22 March 07: core-reg.tex line 160 \iffourarguments throws up an undefined keyword error. I replaced with \iffourthargument and this error went away, but that may not have been the intended meaning. My register seemed to work okay after this fix, but in any case I am unsure what the new third argument to \dostartregister, "type", is to be used for here, so I can't test it. Duncan

lvert rvert etc in math
by Aditya Mahajan 19 Mar '07

19 Mar '07

Hi Hans and Taco, amsmath.sty defines \lvert and \rvert which provide correct spacing when \vert is used as a left or a right delimiter (code at the end of email). I do not completely understand what amsmath is trying to do. Wouldn't \definemathsymbol [lvert] [open] [sy] ["6A] [ex] ["0C] \definemathsymbol [rvert] [close] [sy] ["6A] [ex] ["0C] this achieve the same goal? AMS code: % \subsection{Vertical bar symbols} % Add left/right specific versions of \cn{vert}, \cn{Vert}. Don't % assume the delimiter codes are the CM defaults. % \begin{macrocode} \def\@tempa#1#2\@nil{% \ifx\delimiter#1\@tempcnta#2\relax\else\@tempcnta\z@\fi } \@xp\@tempa\vert\@empty\@nil \ifnum\@tempcnta>\z@ \advance\@tempcnta "4000000 \xdef\lvert{\delimiter\number\@tempcnta\space } \advance\@tempcnta "1000000 \xdef\rvert{\delimiter\number\@tempcnta\space } \else \ifx\@@undefined\lvert % Fall back to cmex encoding since we don't know what else to do. \DeclareMathDelimiter{\lvert} {\mathopen}{symbols}{"6A}{largesymbols}{"0C} \DeclareMathDelimiter{\rvert} {\mathclose}{symbols}{"6A}{largesymbols}{"0C} \fi \fi \@xp\@tempa\Vert\@empty\@nil \ifnum\@tempcnta>\z@ \advance\@tempcnta "4000000 \xdef\lVert{\delimiter\number\@tempcnta\space } \advance\@tempcnta "1000000 \xdef\rVert{\delimiter\number\@tempcnta\space } \else \ifx\@@undefined\lVert \DeclareMathDelimiter{\lVert} {\mathopen}{symbols}{"6B}{largesymbols}{"0D} \DeclareMathDelimiter{\rVert} {\mathclose}{symbols}{"6B}{largesymbols}{"0D} \fi \fi Aditya

New Google Coustom Search
by Mojca Miklavec 13 Mar '07

13 Mar '07

Hello, A tiny addition on the garden: I have changed the google search window on the wiki a bit, so that it now uses "Google Custom Search". Feedback/suggestions wellcome (I need to refine the ntg/tug/ctan searches a bit). Also, if anyone would like to contribute to it (modify it, improve it, add and/or refine searches), just drop me an email and you'll get an invitation. Mojca PS for Patrick: articles are down
