The hpack_filter callback
by Jonathan Sauer 29 Apr '08

29 Apr '08

Hello, in the following PlainTeX example, I try to access all \hboxes created by TeX by using the hpack_filter callback: --------------------------------------------------------------- %&luatex \directlua0{ callback.register('hpack_filter', function(head, group, size, ptype) print() print(group, size / 65536, ptype) return true end) } % From Wikipedia: Beneath a Steel Sky is a British 1994 science fiction point and click adventure game in the cyberpunk genre. It featured comedy elements and was developed by Revolution Software and published by Virgin Interactive Entertainment. It was initially released for DOS and Amiga. Underworld was its working title. The game was the second to use Revolution Software's Virtual Theatre engine, the first being Lure of the Temptress. The game's backgrounds and introduction sequence were designed by Dave Gibbons. The introduction sequence was also included as a separate promotional comic book in some releases of the game. The game is considered to be among the true classics in the early era of graphic adventure games for the early 1990s. This, in part, is related to the mature science fiction theme that was chosen for this game as compared to other games of the same era where fantasy themes (a la King's Quest) had been dominant. Some critics have attributed this difference to the different visions of the adventure game genre between American and European developers. \bye This results in: This is LuaTeX, Version snapshot-0.25.2-2008041019 (Web2C 7.5.6) (HPackFilter.tex adjusted_hbox 469.75498962402 exactly adjusted_hbox 469.75498962402 exactly [1] ) Output written on HPackFilter.dvi (1 page, 2152 bytes). Transcript written on HPackFilter.log. --------------------------------------------------------------- Why does the filter not get called more often, namely once for every line in the output file? Background: I want to calculate the width of the last line of a paragraph so I can adjust spacing following this paragraph accordingly (a bit like display math does it). I tried the buildpage_filter but did not know how to calculate the width of the last \hbox in the list without the \parfillskip glue at the end. Which leads me to another question: When having a \hbox node list, how to I determine the horizontal (when typesetting horizontally) resp. vertical (when typesetting vertically) position of a node relative to the left/top edge of the \hbox? I would think that after line breaking, each node should know this position, but how do I access it? Jonathan

.deps dirs in the repository
by Vladimir Volovich 29 Apr '08

29 Apr '08

Hi! the texlive (and luatex) repository have the .deps directories in the zziplib package with some junk in them checked in: Build/source/libs/zziplib/bins/.deps: -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzip-mem.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzipcat-mem.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzipcat.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzipcat-seeko.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzipdir-mem.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzipdir.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 unzzip.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzcat.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzdir.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzip.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zziptest.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzobfuscated.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzxorcat.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzxorcopy.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzxordir.Po Build/source/libs/zziplib/SDL/.deps: -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 SDL_rwops_zzcat.Po Build/source/libs/zziplib/test/.deps: -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzipself.Po -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzipsetstub.Po Build/source/libs/zziplib/zzipwrap/.deps: -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 wrap.Plo -rw-r--r-- 1 vvv vvv 8 2008-04-07 20:43 zzipwrap.Po is there a reason for this? normally these .deps directories are created during build automatically.

portability fixes for luatex
by Vladimir Volovich 29 Apr '08

29 Apr '08

Hi! while compiling texlive on AIX, i encountered problems with luatex-related files. Most of them are about variable declarations in C files which appear not at the beginning of the block. i spent a few hours on cleaning this up, and attached a patch against current texlive source tree, which changes these files: libs/luafilesystem/src/lfs.c libs/luafontforge/fontforge/Unicode/Makefile libs/luafontforge/fontforge/fontforge/Makefile libs/luafontforge/fontforge/fontforge/namelist.c libs/luafontforge/fontforge/inc/basics.h libs/luafontforge/Makefile libs/lua51/liolib.c libs/luazlib/lzlib.c texk/web2c/luatexdir/image/writepng.c texk/web2c/luatexdir/image/image.h texk/web2c/luatexdir/image/writeimg.c texk/web2c/luatexdir/lua/lcallbacklib.c texk/web2c/luatexdir/lua/loslibext.c texk/web2c/luatexdir/lua/limglib.c texk/web2c/luatexdir/lua/luatoken.c texk/web2c/luatexdir/lang/texlang.c texk/web2c/luatexdir/lang/hyphen.c texk/web2c/luatexdir/tex/postlinebreak.c texk/web2c/luatexdir/tex/texnodes.c texk/web2c/luatexdir/font/luafont.c *please* fix these portability problems, otherwise it will be painful and time consuming to do this again. attached patch is only a suggested way to fix the problem; you may choose to use slightly different approach in some case(s). please let me know if the nature of the problem(s) is not clear from the patch. Best, v.
