Thank you, Taco!

Hi, Taco: After my testing the context/experimental with the trunk version of LuaTeX, the memory usage for loading CJK fonts are much lower than before (300MB vs. 850MB on Adobe Songti Std Light, Windows XP), and the loading time is also shorter, too. So thanks a lot for the work! I think many users on the list will be happy too (like Wolfgang, Yanrui Li, Dr. Kim, Longming Wang, etc...) Yue Wang

Segmentation fault
by Elie Roux 12 Feb '09

12 Feb '09

Hello, As kpse.find_file can't get the path of mpost.mem, I made some experimentations and got a segmentation fault with texlua (revision 1858, on debian/sid 32 bit) on the following code: kpse.set_program_name("toto") local filename = "/var/lib/texmf/web2c/metapost/mpost.mem" function finder (name, mode, ftype) if mode == "w" then return name else local result = kpse.find_file(name,ftype) if not result and name == "mpost.mem" then result = filename end return result end end local mpx = mplib.new { ini_version = false, mem_name = "mpost.mem", find_file = finder } you have to replace filename by the true value of you mpost.mem to get the segfault. Thank you, -- Elie

additional argument to kpse.find_file?
by Elie Roux 12 Feb '09

12 Feb '09

Hello, I found that a problem in the mplib package was to find mpost.mem in TeXLive: It cant be found with kpse.find_file(). I can't be found neither with "kpsewhich --format mem --must-exist mpost.mem", but in TeXLive 2008, it can be found with "kpsewhich --format mem --engine metapost mpost.mem". The problem is that I can't pass the "engine" option to kpse.find_file(). Is it is possible to add it? I think it will benefit more packages than only mplib. Thank you in advance, -- Elie

bug in \parshape with TRT direction
by Khaled Hosny 08 Feb '09

08 Feb '09

\parshape doesn't work as expected for TRT direction in PDF mode, it works fine in DVI mode but in PDF indentation moves the text to the right instead of to the left. This breaks LaTeX lists in TRT direction. See the difference between DVI and PDF output of the attached plain TeX sample file. Regards, Khaled -- Khaled Hosny Arabic localizer and member of Arabeyes.org team

missing signature in the manual
by Elie Roux 08 Feb '09

08 Feb '09

Hello, In the manual one can read: This callback allows you to replace the way LuaTeX fetches lexical tokens. function() return <table> token end I think that the argument(s) of function are missing. Also about buildpage_filter: function(<string> extrainfo) end the function doesn't need to return anything? Finally the char_exists callback is not documented but is in callback.list() Thank you! -- Elie

start_run not working
by Elie Roux 07 Feb '09

07 Feb '09

I tried the following code: \directlua0{ local function simpleone() return "I'm number 1" end local function simpletwo() texio.write_nl("I'm number 1") end callback.register("start_run",simpletwo) } and got no result neither by replacing simpletwo by simpleone in the callback. Is it normal? The simpletwo function works fine with the callbacks "stop_run". -- Elie
