building luatex with external lua headers/libs
by Norbert Preining 27 Sep '07

27 Sep '07

Hi Taco! First of all, thanks for the rework of the zzlib stuff, now it is easy to compile luatex with external zlib libs/headers. Now there is the wish that we compile luatex also with the external lua (5.1) libs/headers. Ok, I tried it, but it doesn't work. My first try on Debian was to replace all references in the source code to ../../lua51/ to lua5.1 because the header files are found here in /usr/include/lua5.1 This worked out quite well (for luatex-api.c), but it stumbled at lua/texluac.c where you try to load several header files which are NOT shipped in our lua51 devel packages. I took a look into the original source and there is written: If you want to install Lua locally, then do "make local". This will create directories bin, include, lib, man, and install Lua there as follows: bin: lua luac include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp lib: liblua.a man/man1: lua.1 luac.1 These are the only directories you need for development. So it seems that you use more than they assumed to be useful. Now the simple question: Do you plan to change this, is there a realistic chance that this can be achieved? (Note that is the start, next are all the other libs ;-) In any case thanks a lot and all the best Norbert ------------------------------------------------------------------------------- Dr. Norbert Preining <preining(a)logic.at> Vienna University of Technology Debian Developer <preining(a)debian.org> Debian TeX Group gpg DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------------- GANGES (n. rare : colonial Indian) Leg-rash contracted from playing too much polo.

Collected notes
by Jonathan Sauer 25 Sep '07

25 Sep '07

Hello, some notes I collected while testing LuaTeX beta 0.11.2: - It should be noted in the manual that \luaescapestring completely expands its parameter. - When setting a \toks register in Lua using tex.toks['foo'] = 'bar' et.al., what catcodetable is used? From looking inside luatex.web, I would guess that, since str_toks is used, all characters get catcode 12, except for spaces, which get catcode 10. A quick test confirms this. In case this is neither a bug nor a temporary hack: This IMO severely limits the usefulness of the tex.toks table, since the toks registers written in Lua later have to be re-scanned in TeX. IMO, tex.settoks should be passed an optional parameter to set the catcode table to use. When using array addressing, the current catcode table should be used (just like tex.print/tex.sprint). - What exactly is meant by "Lua strings are converted to token lists using \the\toks style expansion" (pg. 23)?

Lua states and \dump
by Jonathan Sauer 25 Sep '07

25 Sep '07

Hello, (yes, it's me again ;-) Yesterday I noticed that when \dump-ing a format file, the Lua states are not dumped as well, discarding all initializations made while creating the format. This is not a problem, since the initializations can be put into \everyjob, and of course from a technical angle it would be really difficult to dump a Lua state to the format file (requiring access to the internals of the Lua VM which can change at any time), but IMO this should be noted in the manual.
