Assertion with font expansion

Hello, while using font expansion I get an assertion at the end of the following PlainTeX document: (note that I inserted some debugging messages [the 'luaTeX warning'] into LuaTeX (and damn, does a recompile take long!)) ------------------------------------------------------------------------ -- \pdfoutput1 \pdffontexpand\tenrm 30 10 10 autoexpand\relax \pdfadjustspacing2 % A \tenrm \def\ldots{...} \hsize=10cm Die Strassenbahn ratterte ueber eine Weiche, weshalb die beiden Maedchen wie auch die restlichen Passagiere in der halbvollen Bahn durchgeschuettelt wurden. ``Ansonsten~\ldots'' Ataami hob die Schultern. ``Der Schwarzfahrer hat ja nicht ihn angegriffen oder so.'' \bye ------------------------------------------------------------------------ -- jonathansauer$ luatex Assertion-20080215.tex This is LuaTeX, Version snapshot-0.22.0-2008021521 (Web2C 7.5.6) (Assertion-20080215.tex [1{/usr/local/teTeX/share/texmf.local/fonts/map/pdftex/ updmap/pdftex.map}] ) luaTeX warning: register_fo_entry: fo->fm->tfm_name: cmr10 luaTeX warning: register_fo_entry: fo->fm->tfm_name: cmr10 ../../../../src/texk/web2c/luatexdir/font/writefont.c:378: failed assertion `lookup_fo_entry(fo->fm->tfm_name) == NULL' Abort trap ------------------------------------------------------------------------ -- So for some reason, cmr10 is registered twice.

Program name not set automatically
by Jonathan Sauer 20 Feb '08

20 Feb '08

Hello, the following PlainTeX document results in an error message about kpse not being initialized: ------------------------------------------------------------------------ -- % \directlua0{kpse.set_program_name('tex')} % A \directlua0{kpse.find_file('foo', 'tex')} \end ------------------------------------------------------------------------ --- jonathansauer$ luatex kpseTest.tex This is LuaTeX, Version snapshot-0.22.0-2008021518 (Web2C 7.5.6) (kpseTest.tex ! LuaTeX error Please call kpse.set_program_name() before using the library. l.2 \directlua0{kpse.find_file('foo', 'tex')} ? x No pages of output. Transcript written on . ------------------------------------------------------------------------ --- - According to section 4.9 of the manual, kpse's database is automatically initialized when LuaTeX is used to typeset documents. - The name of the transcript file is empty (even though the transcript is written to 'kpseTest.log'). After uncommenting line A above, no error is generated, and the name of the transcript file printed is not empty anymore: ------------------------------------------------------------------------ --- jonathansauer$ luatex kpseTest.tex This is LuaTeX, Version snapshot-0.22.0-2008021518 (Web2C 7.5.6) (kpseTest.tex ) No pages of output. Transcript written on kpseTest.log. ------------------------------------------------------------------------ --- I looked into the source, and the reason for this behaviour seems to be that 'init_kpse' ('luainit.c') calls 'kpse_set_program_name', but does not set 'program_name_set' ('lkpselib.c') to 1. This is only done by 'set_program_name', which is the C function called by 'kpse.set_program_name'. My modifications to fix this: lkpselib.c line 119: - static int program_name_set = 0; + int program_name_set = 0; luainit.c line 63: - extern int last_lineno; + extern int last_lineno; + extern int program_name_set; line 353: - kpse_set_program_name(argv[0], user_progname); + program_name_set = 1; + kpse_set_program_name(argv[0], user_progname); (BTW: Is there a way to speed up compilation of LuaTeX after making small changes such as these? The build script seems to always recompile everything) I did not find the reason for the missing log file name. Furthermore, I tried to set the program name using '--progname' and got: ------------------------------------------------------------------------ --- jonathansauer$ luatex --progname=luatex kpseTest Abort trap ------------------------------------------------------------------------ --- The reason for this seems to lie in file 'luainit.c', function 'init_kpse', where 'dump_name' is only initialized with the name of the executable when 'user_progname' has not been set (and if LuaTeX is not in IniTeX mode) [BTW: The casts to 'string' in the function are not necessary (anymore?)]. Specifying the format as well using '--fmt' resulted in the message I got the first time. Jonathan

It seems to work as expected on linux with gmake, gcc4 and bash, but I do not dare to make claims for other platforms and combinations. Best wishes, Taco

Luatex beta 0.22.0 released
by Taco Hoekwater 19 Feb '08

19 Feb '08

Hi all, I have just uploaded the archives for luatex 0.22.0. The amount of changes in this beta is not enormous, but there is interesting new stuff (most of that by Hartmut), and it fixes a couple of pretty severe bugs. What's new: * We now have an official bug tracker: http://tracker.luatex.org * A new lua library (img) is added that allows a direct interface to the image handling of luatex. You can use this to include images from lua code instead of via the more traditional \pdfximage cs. See the manual. * An optional equal sign after \{pre,post}hyphenchar is now allowed. * os.exec() has been extended, and os.spawn() added. These functions have support for quoted strings, and they also accept a table with preseparated command arguments. * New string constants os.type and os.name are provided. * node.last_node() is added. This pops and returns the last node from luatex's 'current list' * node.write() is added. This appends a node to the end of luatex's 'current list' (experimental). * The strict check on unicode compliance in pattern files is dropped. Patterns files still have to be in proper UTF-8 encoding, but the error for non-Unicode character values (like 0 - 31 and 127 - 159) is dropped. * \pdfadjustinterwordglue, \prependkern, \appendkern and associated \XXXXcode arrays are gone. * The rest of the pdftex font arrays are now merged into the new luatex font data structure. This means that you can now set up font expansion from lua code, and that a few font-related limits are gone. * The 'top_skip' field in 'insert' nodes is renamed to 'spec', for improved consistency. * kpse.show_path() added. This behaves just like $ kpsewhich --show-path * The unicode.utf8 functions now also accept values in the range 1.114.112 - 1.114.367 that is used by LUATEX for raw byte output. What's been fixed: * Better node memory (de)allocation error tracking and messages * Compilation on MacOSX 10.5 was broken * There was a bug in node.insert_after * Use of \{pre,post}hyphenchar was broken * lfs.permissions was leaking memory * Some warning and error messages are improved a bit * A set of bugs in character protrusion, this seems to be working ok now. * Also, a set of bugs in font expansion. This now works in most cases but is not quite bugfree yet (problematic files for testing are welcomed). * The functions in the kpse library would crash luatex if kpse.set_program_name() was not yet called. gives an error now. * Alignments with spanned columns could cause crashes * A patch is added for problems with filename parsing on the "first input line" (by Jonathan Kew) * The hpack_filter and vpack_filter were only called for lists longer than one node. * Luatex is now more forgiving about font subsets being smaller than their expected size (issues a warning instead of aborts now) * A "double-free ignored" error for paragraphs with lines starting with discarded items was fixed. The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Have fun, Taco

Methinks the recent additions by Hartmut are missing some dependicies (a simple make after the update today failed in luatexdir/lua/limglib.c); also make depend in luatexdir is broken. Best Martin

kpse.find_file
by Reinhard Kotucha 18 Feb '08

18 Feb '08

Hi, I'm using kpse.find_file() in order to determine the location of some config files. In some cases I have to set kpse.set_program_name. Here is the code: _______________________________________________________ #!/usr/bin/env texlua --*- Lua -*- if string.find(arg[0], "/") then -- UNIX path filename=select(1, string.gsub(arg[0], ".*/", "")) elseif string.find(arg[0], "\\") then -- Windows path filename=select(1, string.gsub(arg[0], ".*\\", "")) else -- no path filename=arg[0] end basename=select(1, string.gsub(filename, "\.texlua$", "")) kpse.set_program_name(filename, basename) print(kpse.find_file('pdftexconfig.tex', 'tex', true)) print(kpse.find_file('config.ps', 'dvips config', true)) kpse.set_program_name('xdvi') print(kpse.find_file('XDvi', 'other text files', true)) kpse.set_program_name('dvipdfm') print(kpse.find_file('config', 'other text files', true)) print(kpse.find_file('dvipdfmx.cfg', 'other text files', true)) kpse.set_program_name(filename, basename) os.exit(0) ______________________________________________________ The result is: ______________________________________________________ /home/reinhard/.texlive-alpha/texmf-config/tex/generic/config/pdftexconfig.tex /home/reinhard/.texlive-alpha/texmf-config/dvips/config/config.ps /home/reinhard/.texlive-alpha/texmf-config/xdvi/XDvi nil nil ______________________________________________________ Note that the last two entries are 'nil'. When I comment out the line print(kpse.find_file('XDvi', 'other text files', true)) then I get: ______________________________________________________ /home/reinhard/.texlive-alpha/texmf-config/tex/generic/config/pdftexconfig.tex /home/reinhard/.texlive-alpha/texmf-config/dvips/config/config.ps /home/reinhard/.texlive-alpha/texmf-config/dvipdfm/config/config /home/reinhard/.texlive-alpha/texmf-config/dvipdfm/config/dvipdfmx.cfg ______________________________________________________ Is there anything wrong with the XDvi entry? It produces correct output but why are the other entries 'nil'?

error on luatest
by Hans van der Meer 15 Feb '08

15 Feb '08

I had some testfiles gathered, for example the following does work: % engine=luatex \starttext \startlua a = 1.5 b = 1.8 c = a*b tex.print(c) \stoplua \stoptext But this one gives an error, see the output below. It seems the \startlue...\stoplua is the culprit, because comment them out and the error disappears.
