luatex loading old hyphenation patterns
by Norbert Preining 07 Jul '08

07 Jul '08

Hi Taco, hi all, I am trying to activate the latex based fromats of luatex in the Debian packages, but stumbled over problematic hyphenation patterns. Currently, luatex dies on tex/generic/ukrhyph/ukrhypmp.tex as shipped with TL2007, it contains Ukrainian hyphenation patterns in LCY (cp866nav) encoding. I guess that one cannot do anything here but wait for TL2008 with the new utf8 patterns to hit Debian. Right?

Or are you saying something else? I'm not sure. well, we're are quite content with tex as it is but decided it was time to open it up and use lua for that purpose (with the added benefit of a scripting language that can be used for other purposes); there' snothing wrong with tex as it is apart from some things that we wanted to add to it for a long time and the fact that it had to go open type, unicode etc etc our choices are such that no solutions are implemented (this saves much useless discussions that due to conflicting opinions would lead to nothing) but only mechanisms for users (macro package writers) to add functionality to tex; the basic building blocks remain >> also, our choice for lua, as well as the decisions we make are driven >> by respect for tex (as it is), lua as it is, the things that the >> three of us have wanted to see in tex for ages and of course fun > > My question is not about your choice of Lua, but the decision to embed > rather than extend. As I already mentioned, the socket module extends Lua. we use lua as it is meant ... as an extension language sockets are a general purpose library which is quite something different from tex > Here's another example.

Q: Why does LuaTeX embed rather than extend?
by Jonathan Fine 03 Jul '08

03 Jul '08

I've got a question about a LuaTeX design decision. I'd like to know why LuaTeX embeds Lua in a typesetting program. Perhaps it could instead have extended Lua with a typesetting module. Here's how to embed Lua (in the host program): http://www.lua.org/manual/5.0/manual.html#3 Here's how to extend Lua (with additional 'builtins'): http://www.lua.org/manual/5.0/manual.html#3.16 Here's an example of a Lua extension: http://www.tecgraf.puc-rio.br/~diego/professional/luasocket/ One of the key difference between embed and extend is that Lua socket "is available to any Lua application once it has been properly initialized by the interpreter in use." LuaTeX, because it embeds Lua, is not be similarly available to other Lua applications. -- Jonathan

Different results between dvi and pdf modes

Unicode in \pdfinfo
by Khaled Hosny 03 Jul '08

03 Jul '08

\pdfinfo doesn't seem to support Unicode, when I compile the attached example with luatex I get symbols like Ù‡ØµØ© instead of the proper (Arabic) Unicode strings. Shouldn't luatex default to Unicode here too? Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team
