Snapshot 20070307
by Taco Hoekwater 10 May '12

10 May '12

Hi all, I decided to do a snapshot now instead of waiting for friday, because I want to start concentrating on something else besides font support issues. What's new: * Non-CID PostScript-based Opentype fonts are now combined over the entire document, and properly subsetted. The code is borrowed from xdvipdfmx with some minor adjustments Adding support for CID-keyed OpenType fonts would not be hard but at the moment I lack example input (and incentive). * A small extension to the virtual fonts structure: you can use f.fonts[1] = { 'id' = 38} to do a backreference to a previously defined font. This saves quite a few computations * There was a bug in the handling of \leaders in the output whereby it's width was taken to be twice what it should be while writing to the PDF, fixed now. * The font inclusion code is cleaned up a bit by Hartmut. * Some compilation problems were fixed. * There is (quite a bit of) debugging information printed out when OTPs are in use, because I am tracking down a bug reported by Idris. The input of each and every OTP step is shown on the terminal in a line line this: [57902][1568][58423][1568][58408][1568][58921] those are the decimal values of ocp i/o characters. If you don't need them, don't worry about it. Happy TeXing, Taco ----- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are three new released files: * luatex-snapshot-20070307.tar.bz2 This is the source tree. * luatex-snapshot-20070307-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). * luatex-snapshot-20070307-linux-i386.tar.bz2 An intel 32 linux binary (2.6.17)

XML abilities in LuaTeX
by TeXWorld 19 Nov '09

19 Nov '09

Hello, I'm new to LuaTeX and Lua in general and I try to find tools to process datas stored in XML files. I want to do this with LaTeX (pdfLuaLaTeX in TeXLive 2008) but there's no tool. Contrary to LaTeX, ConTeXt does have abilities to work with XML files. Do you think it could be possible to have LuaTeX equipped with such abilities one day ? I read in the LuaTeX reference that LuaTeX comes with modules such as LuaZIP that is really a good thing. Do you think it would be possible to have something like the LuaXML module added to luatex too ? Jack

The DVI-specific h/vlist_out() functions in dvigen.c are obsolete. Switching between PDF and DVI backend functions works through function pointers (Taco's idea); should be extensible to other backends. Backend functions for PDF and DVI have been shuffled to have the same variable list, needed for the function pointer principle. Some functions are reorganized, with new names, e. g., dvi_place_glyph() and dvi_place_rule(), function special_out() is renamed to dvi_special() corresponding to pdf_special(), function out_what() got pdf pointer as argument. Position variable cur is now local, box_pos is gone, as is global pos. Function do_vf_packet() has been adapted. For synchronization from cur to pos always function synch_pos_with_cur() is used. The synchronization is now done early, so that one should get a valid pos value without the need to resync. This reduces the number of required sync_pos_with_cur() instances in the code. The lua variables (meta-functions) pdf.h and pdf.v should now return the position on the paper (\latelua). ------------------------------------------------------------------------ r2905 | oneiros | 2009-07-23 23:35:00 +0200 (Thu, 23 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/dvi/dvigen.c indent ------------------------------------------------------------------------ r2906 | oneiros | 2009-07-23 23:35:39 +0200 (Thu, 23 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/dvi/dvigen.c init some variables ------------------------------------------------------------------------ r2907 | oneiros | 2009-07-23 23:36:13 +0200 (Thu, 23 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/pdf/pdfshipout.c indent ------------------------------------------------------------------------ r2908 | oneiros | 2009-07-23 23:39:29 +0200 (Thu, 23 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/pdf/pdflistout.c M /trunk/source/texk/web2c/luatexdir/pdf/pdfshipout.c init some variables ------------------------------------------------------------------------ r2909 | hhenkel | 2009-07-23 23:56:16 +0200 (Thu, 23 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/dvi/dvigen.c fix pdf_save_pos_node in out_what() ------------------------------------------------------------------------ r2910 | hhenkel | 2009-07-24 00:14:29 +0200 (Fri, 24 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/pdf/pdflistout.c use dir_orthogonal() ------------------------------------------------------------------------ r2911 | hhenkel | 2009-07-24 00:25:48 +0200 (Fri, 24 Jul 2009) | 2 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/pdf/pdflistout.c movement after hrule in a vlist was wrong ------------------------------------------------------------------------

Luatex 0.42.0 (a snapshot release)
by Taco Hoekwater 22 Jul '09

22 Jul '09

Hi, I have just uploaded the archives for a new luatex release, 0.42.0. NOTE: This snapshot is just for testing the new sources and the updated build process, do NOT trust this binary for production work! There is a whole lot of work done on the luatex internals since the previous beta, and just judging by the amount of work done it seems likely that there will be a few serious bugs remaining. There are two big internal changes. Both changes are invisible to the user, but definately worth mentioning: * There is no pascal (web) code in luatex at all anymore, everything is now converted into plain C and split over about 50 source files. Later, this code will be converted back to CWEB (almost all comments have been kept) but first we want to spend a few months reorganizing the code base. * The PDF backend has been reorganized a lot, and most of the global variables are not put into a single backend structure. Work in this area is not complete, but getting there. The other newsworthy changes are: * There is a new node.tail() function * lua-loaded fonts now support a 'nomath' key to speed up loading the lua table. * A bugfix in the ttf reader for the inclusion backend, and (also in the backend) support for treating ttc files by pretending they are single ttf fonts (both patches from pdftex) * Add Khaled Hosny's man page to the repository * The \pdfcompresslevel is now effectively fixed as soon as output to the pdf file has occurred. * Patched status.filename so that it (nearly) always returns a file name. * fix '\the\delcode' and disable '\the\odelcode', '\the\Udelcode', and '\the\Udelcodenum' * Handle jfifs where either xres or yres is 0 and the other res is != 0 (from pdftex) * The single-argument version of lang.hyphenate() was broken. * Get rid of the \directlua/\latelua number warning. * The Lua coroutine patch (coco) is now disabled on linux powerpc architectures (because it caused crashes) * Removed obsolete pdftex primitives: \pdfoptionalwaysusepdfpagebox \pdfoptionpdfinclusionerrorlevel \pdfforcepagebox \pdfmovechars * The loading speed of large fonts (especially ttf) via the fontloader library, and the inclusion speed for subsetting in the backend have both been improved. * The 'pdf' lua library has been enhanced with various new functions, see the manual for details. * BLT and BRT glyph position fixed. * Various fixes for synctex offsets. * Support for exotic font string encodings has been removed from the fontloader library. * The embedded MPlib is now 1.205. * libpng is now 1.2.38. 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/0.42.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
