We can start a fork of scrp-* on code.google.com/p/ctex-kit, making a usable version, and later ask Hans to merge back into ConTeXt.
it all depends how scrp evolves as it has to deal with more issues too; i will not merge code that i don't fully understand but experimenting does not hurt; one problem with script stuff is that (in the future) it might be closely cooperate with other mechanisms of context (it used to be part of the font analyser, now it's plugged in elsewhere but even that might change, for instance when in upcoming versions of luatex we have a bit more control)
What I have done is only experiment. I will try my best to follow the evolves of the scrp-* files until that day, when MkIV support Chinese typesetting well, comes. I have to introduce MkIV to Chinese users and make them paying close attention to it in this way.
also, some issues will be dealt with in other code in the future (i simply cannot touch all code at the same time) so don't expect mkiv to be finished before 2012 (when luatex 1 is ready); it's a stepwise process and it's only driven by context (i.e. generic code only shows up when context code works okay);
anyhow, as long as nobody tells me what the expected behaviour is, with test code etc i can;t fix anything; one complication (e.g. with chinese) is that over the last few year is got conflicting requests; now, if there are multiple ways to deal with it, then i can implement variants but only if i know the exact conventions (with proper names for them)
Yes. It is a key reson that we are still not familiar with MkIV well now. But with in-depth understanding of MkIV, maybe many suggestions will be post to you. Of course these suggestions should be collected according actual demands by Chinese TeX users group.
for instance when i found out that cjk-korean is not the same as cjk-chinese (one of them) i split the machinery so we're not talking cjk here, but very specific needs; after the split i never tested chinese (no samples) and no one else propbably did that either
keep in mind that context is not meant for one language but for many and that when possible mechanisms need to be able to used mixed; there will never be exclusive solutions for one languages unless it's a very specialized module
anyhow, we can best follow the same route as with other language / script support
- we need consistent specs, or maybe multiple specs as variants - as well as test files for each such case - and then we can look into what can be improved or added
I think that maybe this needs a very long time until CJK users know what each other needs. But three years should be enough :) -- Best wishes, Li Yanrui
