Hi guys,
I missed some of the excitement of the last two weeks because I was away. I tested the latest versions of ConTeXt and luatex and have some problems:
1. Is there a simple switch to between luatex and pdftex? If I want to write typescripts with the new name: syntax, I'd like to have the old typsecripts as well to remain compatible. So: is there something like a simple switch \ifluatex?
2. I tested with a number of OpenType fonts from my Adobe Type Classics CD: ConTeXt Mkiv can address these fonts (which is wonderful), but it does not read the kerning information. I don't know whether this is because Adobe's kerning tables are so big (kerning appears to work with the TeXGyre fonts and Latin Modern) or because the Adobe fonts have these tables included in a somewhat different way.
Will be back with lots of more question re. Greek soon!
All best
Thomas

Hi Thomas,
you can try group your pdfTeX typescripts in
\beginOLDTEX ... \endOLDTEX
and your LuaTeX typescripts in
\beginLUATEX ... \endLUATEX
groups, or you make two extra files--one for pdfTeX and one for LuaTeX--with the file type mkii and mkiv and load them in your typescript file with \loadmarkfile{type-...}.

Sorry, not my price class.

one option is to make two versions (name.mkii and name.mkiv) and then in the name.tex file say \loadmarkfile{name} which will choose the right variant then

depends on the way you define things ... maybe the kerning is language dependent? kern is a feature
in base mode, we use tex's kerning and ligatures and can only have simple replacement, in node mode, mkiv does everything itself

Wolfgang, Hans,
thanks a lot for your replies, that was extremely helpful.

Ah, so \loadmarkfile is the magic switch. I had the idea to use .mkii and .mkiv but couldn't figure out how to. Now that's very useful for all further experiments...

Okay, I tried this minimal definition in my typescript:
\definefontfeature [jens] [mode=node,kern=yes]
\starttypescript [serif] [jenson] \definefontsynonym [Jenson-Roman] [name:AJensonPro- Regular] [features=jens] \stoptypescript
\starttypescript [serif] [jenson] \definefontsynonym [Serif] [Jenson-Roman] [features=jens] \stoptypescript
\starttypescript [Jenson] \definetypeface [Jenson] [rm] [serif] [jenson] [default] \stoptypescript
But still no joy: I don't get any kerning. Tried with all sorts of settings for script= and language=, but to no avail.

there is indeed aproblem with kerning, depends on the kind of lookup (only the real complex contextual ones work); i'll fix it

Very nice sample file... But the 19:22 version doesn't fix it for the Adobe fonts. Kerning has worked for me with the TeXGyre and LM fonts.
Thanks for looking into it, Hans!

that was base kerning -)
what font? i need to look into the font in order to see what is the problem
i'll send you a file showing that at least my fonts work -)

Hi Hans,
can't this be integrated in \usetypescriptfile to look at first for a file with the extensions mkii, mkiii or mkiv and if there is no file use a tex file as fallback.
