It works fine with context, BTW. On Wed, Jun 10, 2009 at 02:49:46PM +0300, Khaled Hosny wrote:

It seems that fonts.register_message is not defined. Pressing enter after that will crash luatex:

This is the bug (a lua or font problem).

This is just a result of the earlier bug. Best wishes, Taco

This is the bug (a lua or font problem).
The font has a ligature that don't have base anchors (that part of lua code is about reporting this, I guess). If I replace fonts.register_message with a dummy function it'll work.

I thought so, I was just wondering why luatex don't exit cleanly (but I think it may be the lua code fault not the engine). Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer

I updated to context 2009.06.10 20:06, but still getting that crash. luatex-fonts.lua doesn't load font-mis.lua, adding it there (and commnting luatex-fonts-merged.lua line) fixes it. Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
