Crail is much employed by the Royal Navy for making the paperweights and ashtrays used inside submarines. --- Douglas Adams, The Meaning of Liff

ConTeXt installtion and Debian

Hi Taco, hi all! (I am sending personal copies since I don't know whether I can mail to the ntg list). First of all thanks for the explanations!

I checked the current zip file and the current ctxtools.rb script, it does nothing else than: - download the current zip - unpack - install the stubs from scripts/context/stubs/* - update the formats. So this is what we have to do in the Debian package, too. This is not hard, in fact most parts are already done. The only thing we have to do is create a way for the user to choose which formats should be generated. I will think about this. But for the search pathes, we will adjust the Debian texmf.cnf file, to get different engines loading differen cont-en.fmt files. Thanks.

Re: [NTG-context] how to define a new math symbol
by M.J. Kallen 25 Oct '06

25 Oct '06

Great, it works! Running "texexec --pdf test-prodint" worked immediately, but "xdvi test-prodint.dvi" gave me an error relating to mktexpk not being able to create a bitmap font. Solved this problem by running "updmap --enable Map prodint.map". I don't think I could have done this myself, as I do not understand some of the steps in your solution. Thank you very much!

That last bit of information is crucial, because there is a difference between font handling between CM/Lm and commercial fonts. I've been skyping with Hans and he came up with the code below. You can use the font files from the LaTeX zip, you just have to make sure that pdftex can find the (map) file, of course.

Taco, I'm not sure I understand your question. I'm using TexLive on a linux system. I do not use any other fonts other than CM. The file prodint.afm has the following contents: StartFontMetrics 4.0 Comment This is prodint.afm created from prodint.pfb by t1lib V. 1.0.0.

Another problem with this approach is the fact that this does not define a MATH symbol, which is really what I would want. Based on the LaTeX style file prodint.sty, I'm guessing I'll at least need a command like: \definemathsymbol [prodi] [op] [prodint] ["xx] but I can't figure out the usage of this command. I also suspect that I can not used the prodint.tfm file, supplied with the LaTeX package, but need to run Texfont to create one for ConTeXt. Can you confirm this? I greatly appreciate any help!

Hardcoded options in the Ruby scripts
by Richard Gabriel 25 Oct '06

25 Oct '06

Hello Hans, I'm still wondering why there are certain formats hardcoded in your scripts and how the "make all formats" feature does (not work). See scripts/ruby/base/tex.rb: Lines 131-137: Here are a few languages predefined which texexec "knows". If I want to add a format for another language, I have to add a new line here. Line 339: Here are the "default" TeX formats defined. No problem to consider something as default ;-), but the point is that "texexec --make --all" actually does "make all DEFAULT formats", NOT "make all AVAILABLE formats". :-( Anyway, the main problem I see is altering of a script which comes with the ConTeXt distribution - the changes made into this scripts must be done again and again after each update. My suggestion is: 1. To put the format definition into a separate file (like user.rb or so) which won't be owerwritten in any case. [Note: cont-usr.tex is a good analogy to this] 2. "Make all" should make ALL the defined ConTeXt formats, not the default ones. Thanks, Richard

how to define a new math symbol
by MJK 24 Oct '06

24 Oct '06

Hi, I would like to use of the product integral (a curly \prod-like symbol which is to \prod what \int is to \sum) in Context. There is a LaTeX package (not official) available from Richard Gill's website (http://www.math.uu.nl/people/gill/, all the way at the bottom), which supplies a .sty file with the following contents: \ProvidesPackage{prodint} \DeclareFontFamily{U}{ProdInt}{} \DeclareFontShape{U}{ProdInt}{m}{n}{<-> prodint}{} \DeclareSymbolFont{Prodint}{U}{ProdInt}{m}{n} \DeclareMathSymbol{\prodi}{\mathop}{Prodint}{80} %80 prodinttext \DeclareMathSymbol{\Prodi}{\mathop}{Prodint}{82} %82 prodintdisplay \DeclareMathSymbol{\PRODI}{\mathop}{Prodint}{84} %84 prodintbig \endinput It also supplies a bunch of fontfiles, i.e. prodint.{afm,pfa,pfb,tfm}, and a map file prodint.map. As you can see, the package supplies three commands: \prodi, \Prodi and \PRODI, corresponding to three sizes. My question(s): how can I define similar commands (I'm guessing \definemathsymbol would be required) to use this symbol in Context? Is it possible to use the fontfiles supplied in the LaTeX package or should Texfont be used to enable the symbol in Context? Thanks, Maarten-Jan

Updating on Windows
by Jeff Smith 23 Oct '06

23 Oct '06

Hello all! Quick question here because the Wiki is silent on this. When I want to (manually) update my ConTeXt windows (stand-alone) installation, do I only need the following two files: cont-tmf.zip cont-win.zip Or is there more? I know ScITE is supposed to have an "Update ConTeXT" option but I don't use this editor anymore. I found a nifty one called PSPad with a better interface (in my opinion -- and it also supports Unicode, so yay!) and it supports TeX very well. I had a lot of fun using its integrated Lorem ipsum generator when testing stuff. :-) Jeff
