Hi,

in MkII I set \setupcolors[state=start] to activate defined colors (for text, numbers etc.), and \setupcolors[state=stop] to set these colors to black.

Now, in MkIV \setupcolors[state=stop] does set these colors to gray. Not to black. [Log: "color : system gray is global activated"]

What is the key to set either "color is color" or "color is black" again?

i don't think mkiv has such an option (but maybe i'm wrong). how about defining some color palettes then? this should work with both marks.

\definepalet[coloredtext][...] \setuppalet[coloredtext]

\startmode[black] \definepalet[blacktext] [red=black, blue=black,...] \setuppalet[blacktext] \stopmode

as colorspace info travels indepently you can say

\attribute\colormodelattribute\attributeunsetvalue

i'll add

\setupcolors[state=stop,conversion=never]

@ Hans/Mojca: Is luatex in standalone suit outdated? Steffen Anfang der weitergeleiteten E-Mail:

Hello Steffen,

have you ever tried the context version of TeXLive 2011 and than the updated version of it? There is made use of an updated version of luatex. With that version I have fewer problems with for instance TikZ. The stable version and the beta version of context both use an old version of luatex ( beta-0.70.1-2011052008). There is some luatex version beta-0.70.1-201106.......?? Here at my work I cann't try your example, because I have here the context version of Ubuntu and that processes with the old version of luatex,

Kind Regards,

Rene' ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki!

Hans, does version beta-0.70.1-201106... fix the color conversion clash? As I do not now the background I can't decide wether it is recommended to compile this version ... Steffen

Hello luigi, indeed the ConTeXt version 2011.05.18 18:04, with the LuaTeX version beta-0.70.1-201106141 is used in TeXLive2011. These versions give me fewer problems with TikZ than the version beta-0.70.1-2011052008 of LuaTeX, with the same ConTeXt version. For instance, frames are put over each other in the stable and the beta version of ConTeXt. But with the TeXLive2011 version, these frames are nice separated of each other and I have no problems with error messages about "catcode". With the stable and the beta version of ConTeXt the process stops with error messages about "catcode". And till now I have no problems with the colors. Is there somewhere a howto, which describes how to compile something from svn? I have never done such a thing, Kind Regards, Rene'

No, I don't even remember writing something like that (but I don't deny it either). Patrick

Hello Luigi, Stephen and Patrick, thanks for your reactions. At home I tried to process the example (08-01-2012) of Stephen with the TeXLive2011 version of context, but I got the same errors as the stable and the beta version of context. Thanks for the report of how to compile something with svn. Which person will ever buy "Hans's"-keyboard, that of http://www.artlebedev.com/everything/optimus/popularis almost 10 euro for each key. I like it to give my lectures at a blackboard with chalk. At the blackboard I design my own keys, infinitely many, Kind Regards, Rene'

Maybe the next kind of board will be the Interactive whiteboard http://en.wikipedia.org/wiki/Interactive_whiteboard (+/- like a configurable keyboard, only on the wall)

ah, that kind of crap .. they introduced that in all dutch schools .. real interesting to see how this 1024x768 resolution works out in the back of the room, esp when publishers of stuff use some 30% of the available space for useless borders and such .. and of course such boards need to be compensated with special (paper based) programs to aid those with reading problems (I've heard of cases where very young kids had to start wearing glasses). I wonder how this would work out: http://www.3noobs.com/microsoft-surface-2-0-as-samsung-sur40-specs-price/ (Ok, off topic, but to some extent it can influence user interfaces, editing and proofing in the future.)

Hello Hans, just back from the lecture I have given and I got an idea: Take not that keyboard of you, but take the Maximus (1430 euro!) or the Tactus, see http://www.artlebedev.com/everything/optimus/aux/ Prepare with ConTeXt a number of keys, for instance parts of mathematical formulas and functions, or parts of molecules out of the chemistry. Put them in the keys of one the keyboards, mentioned above and there can be given a lecture with readable formulas. By touching those keys you get a nice written text. Or some key, that you get a nice table ( prepared by ConTeXt) at the screen. And such that it can be filled by handwritten information, using some tablet or otherwise. May be it is already possible for a virtual keyboard on a touchscreen or something like that. A ConTeXt package for the preparation of the keys of a virtual keyboard? It is just an idea, really I have no idea how to realize it, Kind Regards, Rene'

They also offer a full-size keyboard: Optimus Maximus (http://www.amazon.de/getDigital-de-Optimus-Maximus/dp/B001M44ZB8/ref=sr_1_10?ie=UTF8&qid=1326183660&sr=8-10) At amazon.de this is tagged "EUR 1.804,00 (EUR 902,00 / kg)": Now, what's more cost-efficient ... 10 euro for each key or 902 euro for each kilo? ;o) Steffen

It might pay back when editing multiple scripts (now I always have to mess with numbers). And I would buy one if I had the money, of course because of those scripts, but also because this kind of adaptive stuff is the future. I guess it needs a company like logitech or so to make it cheap and large scale.
