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

tex.sprint, -- and \par: Crash
by Jonathan Sauer 06 May '08

06 May '08

Hello, %&luatex \pdfoutput=1 \directlua0{\unexpanded{ tex.sprint('--') % A % tex.sprint('-- ') % B tex.sprint('\\par') }} \end This results in (I'm using the svn trunk as of friday afternoon): This is LuaTeX, Version snapshot-0.25.3-2008050416 (Web2C 7.5.6) (DashCrash.tex../../../../src/texk/web2c/luatexdir/font/luafont.c:1691: failed assertion `cur != null' TeX returned non zero exit status Using (B) instead of (A) works. If line (A) is commented, everything works. So it seems that there is a problem with a dash followed by a \par when output using tex.sprint. Jonathan

expansion of ~ in luatex
by Norbert Preining 06 May '08

06 May '08

Hi Taco, could you implement the expansion of ~ to $HOME for unix and to %USERPROFILE% for win32 as done in the current kpathsea library? Or do you plan to incorporate the new version of kpathsea? I ask because currently I have to hack around that quite a bit in the TeX Live installer and support programs to make it work equally on win32 and unix.

process_input_buffer-callback and tex.sprint
by Jonathan Sauer 06 May '08

06 May '08

Hello, take the following PlainTeX file: %&luatex \pdfoutput=1 \directlua0{\unexpanded{ callback.register("process_input_buffer", function(line) callback.register("process_input_buffer", nil) tex.sprint(" world!") return line end) }} Hello \bye Using the svn trunk as of friday afternoon, this results in a PDF file containing the world "Hello". " world!" is missing for some reason. There is no warning in the log file. Does tex.sprint not work in a callback (or at least in the "process_input_buffer" callback)? Is this the same limitation as noted in the manual: tex.print() and tex.sprint() do not work if \directlua is used in an otp file (in the output of an expression rule) (Above example is actually slightly less contrived than it seems, because when using tex.sprint, it is possible to specify a catcode table, whereas the callback cannot influence the catcodes of the returned line in any way.)

small changes for solaris
by Vladimir Volovich 06 May '08

06 May '08

Hi! while compiling luatex on sparc sun solaris using sun studio 11 compiler, i discovered two more problems, and attached a small patch. it appears that the test for the __sun__ macro only works on sun when using gcc; when using sun studio, one should look for __sun instead (i.e. __sun__ is defined in gcc, and is undefined in sun studio compiler). attached patch fixes compilation problems which arise because of incorrect detection of the platform. please apply to texlive repository too. (another small problem is that libs/luafontforge/fontforge/fontforge/Makefile compiles splinerefigure.o without passing CFLAGS, striving to remove possible optimization settings, but CFLAGS is not only used for passing optimization options, but e.g. to select the target instruction set: e.g. -xarch=v8, and removing CFLAGS compiles to the wrong target instruction set, making the luatex executable which links with this file wrong; i worked around this by setting the XCFLAGS to -xarch=v8, which is used to compile splinerefigure.o). Best, v.
