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.

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
