alloc@0, etc, from plain.tex
by Jesse Alama 09 Aug '10

09 Aug '10

There's a plain TeX package (bussproofs.sty from CTAN; I realize that the file ends with ".sty" but it's intended to work in plain TeX) that I'm trying to get working with ConTeXt. I'm stuck at one point though: the package has the statements \def\newcount{\alloc@0\count\countdef\insc@unt} \def\newdimen{\alloc@1\dimen\dimendef\insc@unt} \def\newskip{\alloc@2\skip\skipdef\insc@unt} \def\newbox{\alloc@4\box\chardef\insc@unt} ConTeXt complains because it doesn't know what alloc@0, etc., are. Any advice for how to import this functionality from plain.tex into ConTeXt? thanks, Jesse

You saved my day, thanks a lot! I think Hans tried to explain it to me but I didn't get him. I have read the documentation about typescripts but I did not understand it well. Let's say I have the following simple example: \starttypescript[sans][test] \definefontsynonym[Test] [file:FuturaStd] [features=default] \stoptypescript how can I use it in 'usetypescript' now to change the font type? I tried \usetypescript[test] and \usetypescript[sans][test] followed by \defineframedtext[important][style={\switchtobodyfont[test,24pt]}] but it didn't work (to be specific, the font size is ok, but the font type did not change) Armin ___________________________________________________________ WEB.DE DSL SOMMER-SPECIAL: Surf & Phone Flat 16.000 für nur 19,99 ¿/mtl.!* http://web.de/DSL-Doppel-Flatrate/

referenceformat, text
by Yury G. Kudryashov 09 Aug '10

09 Aug '10

Hi! The following code: \definereferenceformat[lem][text=Lemma] \inlem[lem:mylemma] produces just a number, no "Lemma " prefix. I've sent a patch to fix it a while ago. Could you please apply it, or tell me why you don't want to apply it? -- Yury G. Kudryashov

Some Experiences
by James K. Peterson 09 Aug '10

09 Aug '10

Hi all, I do a lot of LaTeX writing as my stuff is very math intensive, but I have a lot of interest in ConTeXt as I would like my books to look better. Anyway, I try on and off to get ConTeXt running so I can experiment. I just spent a pleasurable day playing. Here is what I found. It was pretty easy to install the newest minimals. I just followed the instructions and installed it in a local place separate from my texlive2009 installation. I spent a lot of time with a direct update of ConTeXt into my texlive2009 folder (yes, I know I was doomed but I was on a roll). I found the usual errors running either luatools --generate or mtxrun --generate and also context --make All the files needed to make this work are actually installed, but the problem is the way luatools finds stuff and caches it. Something is wrong there. The files that are in the folder can't be located. Also, with my local minimals installed and trying to add ConTeXt to my texlive2009, luatools seemed to find the ConTeXt stuff from both minimals and texlive2009. That was not good, but temporarily removing the minimals did not change the bad results, still I have no idea how to get luatools to ignore the minimals folder when it is setting up the cache. Finally, this all started because I am tired of my bad chemical drawings in my books and wanted to use the package m-ch-en in LaTeX. The original context supplied with texlive2009 wouldn't let me compile a m-ch-en source so since I am still heavily using LaTeX, I wanted to update luatex, context etc to see if I could get it to work. I still can't use context from texlive2009, but with my updates I can compile m-ch-en source. So at least a small win. The ConTeXt stuff is fascinating and I am moving towards it, but I need to do it in baby steps and I need to do it with a concomittant LaTeX installation. So I will eagerly await any sort of a fix for a LaTeX/ConTeXt combined world while I continue to learn and move away for LaTeX. As a long time user of LaTeX, I know its limitations very well and ConTeXt will allow me to do more interesting things. Keep up the good work. I read the digest every day and look around the wiki too. Thanks! Jim Peterson

949 more named colors

Hi, I've put up a small script that generates color definitions from Randall Munroe's color survey for use with ConTeXt.[1] This yields 949 more rgb colors that might be more adequately labeled than e.g. those from X11.

Commands based on previously defined commands, with fixed values for arguments

How can I define a command by reusing the already defined command? \def \HelloTwo #1#2 {Hello, #1 and #2!} \def \HelloOne #1 {\HelloTwo{#1}{Vedran}} This gives me a "Runaway argument". -- Vedran Miletić

abbreviations as macros
by ivo welch 07 Aug '10

07 Aug '10

Hi Hans: This is asking Armin Varmaz' question in a different way, although I know even less. I would like to define a macro that is just an abbreviation. For example, say I want to define a snippet \NPV which provides the text NPV$_0$, and NPV is in textfont while 0 is in mathfont. This should work everywhere---formulas, subscripts, footnotes, etc., and automatically appear in the correct sizing. In LaTeX, this is easy to do: \newcommand{\NPV}{\text{NPV\ensuremath{_0}}} I can now use \NPV\ in formulas, footnotes, subscripts, titles, etc., and it is properly sized everywhere. Is there a recommended way to do this on conTeXt? regards, /iaw
