Hi,

Your test example works well.

I have a few days old binaries from pragma folder too, downloaded and 
set up with my Windows installer
http://minimals.contextgarden.net/setup/context-installer/

Best,

i agree that it's no bug, just different handling in comparison to mkii.
if i think about it, it works as it should. mhh, what are we talkin'

if you consider how color is implemented, this is actually not a bug

what do you expect in the following case ...

	\setbox\scratchbox{hi there}

	\hbox{\bf \copy\scratchbox}

till we had luatex, only fonts could be considered an attribute, and a 
rather limited one: each glyph node has a font id attached; luatex has a 
more generalized concept, attributes, and *each* node can have attributes

colors (and more) in mkiv are implemented using attributes and therefore 
things behave a bit different

i'm still not sure what mkiv should provide, since both methods have 
their (dis)advantages

and so it may not come as a surprise that there is some hackery around 
this compatibility issue ..

% engine=luatex

\setupcolors[state=start]

\enableattributeinheritance
\starttext

\newbox\TESTbox \setbox\TESTbox\hbox{Silence is sexy.}

\hbox{\color[red]{Silence is sexy.}{\color[blue]{Silence is sexy.}}}

\hbox{\color[red]{\attributedcopy\TESTbox}\color[blue]{\attributedbox\TESTbox}}

\stoptext

i may reimplement this at some point using the new attr feature that 
comes with boxes (i had no time yet)

when testing this a few minutes ago, i found out that this mechanisms 
was disabled; i uploaded a beta that should work ok

it will take a while before such thinsg are sorted out, esp because 
there is no best way, most logical approach, no method that makes most 
sense (which is also why it's left to macro packages to deal with it)

(btw, this phenomena is mentioned in mk.pdf, of which there is an 
updated version)

Same here (it looks that previously i was looking at xetex's output):

This is LuaTeX, Version snapshot-0.20.2-2007122521 (Web2C 7.5.6)

ConTeXt  ver: 2007.12.21 20:50 MKIV  fmt: 2007.12.25  int: english/english

Even here no colors. I'm  using last stable context.

I just succeeded in building latest luatex and generating all the require formats
and your test file works here ;)

Hi Peter,

I have the same problem on my system, the text in the second line is
black and has no colors.

ConTeXt  ver: 2007.12.21 20:50 MKIV  fmt: 2007.12.21  int: english/english
This is LuaTeX, Version snapshot-0.20.2-2007121821

LuaTeX version 

 BTW: The latest was for mkii and should't be used at
the moment.

Wolfgang

  Yes, Mark IV fails on my machine too (ConTeXt  ver: 2007.12.21 20:50 MKIV).

  I had a look at that but I couldn't figure out why, and I don't have
that much time right now.  The problem seems to be that ConTeXt doesn't
find the fonts, which doesn't make much sense since the installation has
not changed in months (except that we upgrade to the latest beta each
time it is released).

lost colors (mkiv)

[Peter Rolf]

Hi,

can anyone with an actual *luatex* test, if this fails (live ConTeXt is
broken). My binaries are from the minimals at contextgarden (pragma
tree), ConTeXt is the latest beta.


\setupcolors[state=start]

\starttext

\newbox\TESTbox
\setbox\TESTbox\hbox{Silence is sexy.}

\hbox{{\color[red]Silence is sexy.}{\color[blue]Silence is sexy.}}
\hbox{{\color[red]\copy\TESTbox}{\color[blue]\box\TESTbox}}% no colors
with mkiv

\stoptext
