XeTeX no longer working

XeTeX no longer working

[Christopher Creutzig]

Salvete,

  since mail directly to Adam Lindsay does not seem to get through (I 
never got a reply, even when asking if it had got through, so I'm 
assuming it didn't), sorry to everyone not interested in XeTeX.

  After upgrading to tetex beta, XeTeX 0.88, and ConTeXt 2004.10.07, I'm 
suddenly running into problems:

\resetspecials
\defineoutput  [xetex]  [xtx]
\setupoutput[xetex]
\usetypescriptfile [type-xtx]
\definetypeface[Hoe][rm][serif][hoefler]  [default][encoding=unicode]
\setupbodyfont [Hoe,rm]%
\setupcolor[state=start]

\starttext
{\red test}
\stoptext



! Undefined control sequence.

                                                   \fi \fi
...
l.11 {\red
            test}


  Is there a newer version of XeTeX support available?  (spec-xtx.tex 
from context/base, which is used, unfortunately only lists 
"version=2004.*.*".)

  I believe the problem is in

\ifx\colorhexcomponent\undefined

     % this will be added to colo-hex.tex

\else

     % because we intercept the zero condition, the .23pt in 1.23pt will 
disappea
r in the
     % ifcase zero part branch

     \def\colorhexcomponent#1%
       {\ifdim#1\points<.005\points
...

  Why is there an empty first branch in the if?

Regards,

Christopher,

Sorry. My email answering has been sporadic in the past few weeks because
I have been travelling. (I need to check if some of your mail got spam-
filtered, as well!)

The problem is with the changes that went into the ConTeXt distribution.
Since you're running an up-to-date XeTeX, a temporary workaround is
replacing the following:
>\resetspecials
>\defineoutput  [xetex]  [xtx]
>\setupoutput[xetex]

...with:
\setupoutput[dvipdfmx]

It's not entirely accurate, but XeTeX now supports 85% of the important
dvipdfmx specials, so the next spec-xtx will inherit from dvipdfmx.

best,
adam

I'm sorry to barge in on this discussion, but this XeTeX thing?  Are you
running Mac OS X to use it, or is there an easy way to get it working on
UN*X?  I tried finding information on setting it up on UN*X, but it
didn't seem there was any.

Thanks,
	nikolai

Hi Nikolai,

Sorry to exclude you, but this XeTeX thing is totally a MacOSX thing.
It's an evolution of TeX/GX, and uses Apple's advanced typography APIs
for font handling. It means *massive* simplification of font
installation, special feature use, and Unicode, but at the cost of cross-
platform-ness and some backward compatibility (mostly in legacy fonts). 

The backward compatibility is improving with each release, but the thing
is never going to be cross-platform with respect to Apple's APIs. If you
do get your hands on a MacOSX system, I highly recommend giving XeTeX a try!

As I feared :-(.

OK.  Thanks for the incredibly quick response,
