Luatex 0.51.0 announcement
by Taco Hoekwater 15 Mar '10

15 Mar '10

Hi, I have just uploaded the archives for a new luatex release, 0.51.0. New features: * Various small manual improvements. * The backend message "cannot open Type 1 font file for reading" now reports which Type1 font it was looking for. * Fontforge clears some font names at loading time that will be refilled in at font generation time, but the fontloader should not do that. Patch from Khaled Hosny. * New synctex code imported from TeXLive. * luamd5/md5.h is renamed to luamd5/luamd5.h to avoid confusion. * Embedded mplib is now 1.209. * Some experimental tweaking of buildpage_filter, see the manual for details. * Luatex now detects kfreebsd (from Alan Braslau) * The new lua function tex.sp() converts a string to a number representing scaled points. * There is now support for revision numbers in the banner and stats library again. * The command line help and manual documentation page is extended. * node.hpack() now also accepts "cal_expand_ratio" and "subst_ex_font" modifiers. * node.hpack() and node.vpack() now give back the badness of the box as second return value. * node.copy_list() now allows a second (stop) argument, this stopper is not copied. * new lua functions in lfs: lfs.readlink() and lfs.shortname(). * new lua function tex.tprint() that can combine multiple catcode regime prints in one function call. * new lua sub-table: tex.nest[] (read/write access to the semantic nest state). * New lua functions in kpse: kpse.lookup() and kpse.version(). See the manual for more details. * New lua function tex.shipout(). Bug fixes: * There problems in the pdf output for Type3 (pk) fonts. * Fix a bug that allowed bad commandline quoting. * Fix a bug that sometimes caused crashes when \pdfprotrudechars. * The build script now exports CONFIG_SHELL to avoid problems with /bin/dash. * The was a bug in the generated /Image /ProcSet. * status.font_bytes reported the wrong value. * Lots of compiler warnings are removed (thanks Javier Mugica). * Patch to fontloader.info() to accept filenames with embedded parentheses. * Fix a \write error with docstrip package. * Fixed a crash on AdobeMyungjoStd-Medium.otf. * Fix coco stack overflows, needed for lpeg. * \pdfcompresslevel wasn't initialized for early immediate objects. * Fix for slanted fonts when HZ was on (slant angle was multiplied). * When concatenating content streams, put a space between them. * Allow pfb lines to end with \r as well as \n (for msam10.pfb). * Fix the internal string->scaled point conversion in the lua interface. * Memory leaks in the fontloader removed, thanks to patches from Elie Roux. * Fix a crash caused by the combination of coroutines and font.each(). Removed features: * Support for Type3 .pgc files (nobody used them). The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.51.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

luatex 0.51.0 and libpoppler 0.12.* compile error
by Norbert Preining 14 Mar '10

14 Mar '10

Hi Taco, hi all, I was just playing around to get 0.51.0 compiled with libpopper, without success unfortunately. I have already one patch in my patch queue to help (for the pdf version, see attached patch), but there is a new problem which I tried to find a way around without success. Maybe someone here has an idea: ../../../source/texk/web2c/luatexdir/image/pdftoepdf.cc: In function ‘void write_epdf1(pdf_output_file*, image_dict*)’: ../../../source/texk/web2c/luatexdir/image/pdftoepdf.cc:663: error: ‘class Page’ has no member named ‘getResourcesNF’ ../../../source/texk/web2c/luatexdir/image/pdftoepdf.cc:669: error: ‘class Page’ has no member named ‘getMetadataNF’ I checked the header files from poppler and there is nothing like *NF :-( Thanks for any suggestions, and all the best Norbert ------------------------------------------------------------------------ Norbert Preining preining(a){jaist.ac.jp, logic.at, debian.org} JAIST, Japan TU Wien, Austria Debian TeX Task Force DSA: 0x09C5B094 fp: 14DF 2E6C 0307 BE6D AD76 A9C0 D2BF 4AA3 09C5 B094 ------------------------------------------------------------------------ He expanded his chest to make it totally clear that here was the sort of man you only dared to cross if you had a team of Sherpas with you. --- Douglas Adams, The Hitchhikers Guide to the Galaxy

Re: [Dev-luatex] bug 345: Kerning is not perfect in math mode

Since I do not seem to have access to this: http://tracker.luatex.org/view.php?id=345 I am not quite sure what you are tryinng to hack. It appears to be something to do with the 2nd plane math characters (something I have gone around many times on the MathML group). One major problem is that these character slot repertoires are incomplete in incompatible ways but that may not affect what you are doing here. I would have thought that when using 'standard tex-like input' and tex-like processing there are a lot of arbitrary decisions to be made. It seems unlikely that an assumption about catcodes is a good solution: but neither are catcodes in the first place and making assumptions about 'math fonts' was no better. So why not replace one set-up assumption by another? other useful(??) questions are: what would the catcode of this bizarre set of math slots be? More relevant: What exactly is the spec for how you want these things to behave in a world of large fonts and character sets? What does 'compatibility' mean when this new world is opened-up? chris --------------------------------------------------------------------------- The Open University is incorporated by Royal Charter (RC 000391), an exempt charity in England & Wales and a charity registered in Scotland (SC 038302)

bug 345: Kerning is not perfect in math mode
by Taco Hoekwater 13 Mar '10

13 Mar '10

Hi, See http://tracker.luatex.org/view.php?id=345 I've tried to fix this by checking the \catcode of the current character for 'new math fons' instead of relying on the font's space() fontdimen like TeX82 does. This fix is based on the assumption that the 'high numbers' won't have \catcode 11, so that only the low upright alphabetic characters will have the italic correction stripped, and those are exactly the ones we want to reach in 'typical' new math input: this nicely covers operators that have 'names' like \sin, and any other uses of \rm in math mode. The downside is that this fix will break stuff like $ A {\it forces} B $ but I see no way to tackle that automatically. Best wishes, Taco
