Crash with invalid numeric parameter to node.type
by Jonathan Sauer 16 May '08

16 May '08

Hello, $ luatex This is LuaTeX, Version snapshot-0.25.3-2008050416 (Web2C 7.5.6) **\directlua0{print(node.type(100000000))} ! Emergency stop. <*> \directlua0{print(node.type(100000000))} No pages of output. Transcript written on texput.log. This is most likely because function "do_get_node_type_id" in lnodelib.c does not check the range of the numeric parameter. Jonathan

node.insert_before
by Jonathan Sauer 13 May '08

13 May '08

Hello, when trying to insert a node using node.insert_before, and if <current> is equal to <head> (to make <new> the new head), the following error is generated: Attempt to node.insert_before() a non-existing node The node I want to insert exists, as well as <head> and <current>. If I manually special-case the code, just like Heiko Oberdiek does in his luacolor package, everything works perfectly. Is this a bug? A feature? I'm using the svn trunk from last friday. Jonathan

State of OpenType support
by Khaled Hosny 08 May '08

08 May '08

Hi all, I've some Arabic fonts that use OpenType features extensively, I tested them with luaTeX but there are many broken features. I wondering, is OpenType support considered more or less done, and thus I might be encuntring some bugs, or there still some work to be done in this aspect and I shouldn't bother you with bug reports. (I'm using 0.25.3-2008041821 with ConTeXt) Thanks, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

A few idle questions...
by David Kastrup 07 May '08

07 May '08

Hi, XML processing is sort of the rage of the day, and ConTeXt also has some support for it. What I have been wondering is whether luaexpat is on the list of libraries where inclusion into LuaTeX would be considered. Either directly, or as a configuration option when compiling. For processing pure XML files or fragments, this would seem like interesting infrastructure. Another question: I found inclusion of the the Coco patches quite interesting. An application that came immediately to my mind was having a control flow written in Lua that feeds TeX code into the TeX interpreter and works with the result from executing these TeX instructions, by yielding a Lua coroutine until the executed TeX code finally resumes it. Was that the basic intention? Are there any practical experiences with Coco in LuaTeX already? All the best, David -- David Kastrup
