MetaPost 1.890 announcement

11 Mar '14

I am happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.890 ---------------------------------------------------------------------- This is a preliminary release in preparation for TeX Live 2014. It is main new feature is the promised ‘decimal’ number system that is now operational (but has not been tested extensively yet). Also, some of the open bugs have been fixed. A source archive can be downloaded from the files section at https://foundry.supelec.fr/projects/metapost/ You can also do an anonymous subversion checkout: $ svn checkout --username anonsvn https://foundry.supelec.fr/svn/metapost/tags/1.890 The password is anonsvn I am no longer able to cross-compile for Win32, so Windows users will have to wait for Akira Kakuto and/or Mojca Miklavec’s binaries. ---------------------------------------------------------------------- What is new in MetaPost version 1.890: ---------------------------------------------------------------------- * The numbersystem 'decimal' is now operational. * New internal: 'numberprecision', for use with 'the 'decimal' number system. The (numeric) value expresses the desired calculation precision, in decimal places. system default min max ============================ scaled 10 10 10 (assignment effectively ignored) double 16 16 16 (assignment effectively ignored) decimal 34 1 1000 * Bug fix: in the 'double' numbersystem, if X = scantokens decimal X: will now always be true, because the 'decimal' operator now has the same resolution as the scanning routine (which is two decimal places more than in the previous release). * Fixed a bug in the handling of the / operator (wrong precendence). * Fixed a bug in arctime (did not handle negative values currectly). * Fixed TFM generation issues (various scale-related errors). * Fixed application crashes when there was no TEXMF tree to be found anywhere. * It is no longer possible to assign to the 'numbersystem' internal. * There is a new definition of 'drawdot' in plain.mp. * PNG output did not output anything for draws of a single point. * Metapost now prints the full name of any preloaded files. * Fixed a bug in the handling of labels with embedded ascii zero(es). * Fixed handling of unknown command-line options, the reporting on used libraries in the --version output, and the banner line. Have fun! Taco Hoekwater, for the MetaPost team, March 11, 2014

file-job.mkvi: \startproject
by Wolfgang Schuster 02 Mar '14

Hi, shouldn’t the \starttext and \stoptext calls be removed from \startproject and \stopproject? \unexpanded\def\startprojectindeed {\starttext \pushsystemmode\v!project \setsystemmode\v!project} \unexpanded\def\stopprojectindeed {\popsystemmode\v!project \stoptext \signalendofinput\v!project} When you have a document in this form <example> \project[myproject] \startprodct[myproduct] … \stoproduct </example> you won’t get a pdf file because the project file closes the document with its \stoptext call.

Hi, The line 277 with \newtoks\everysetupdocument can be remove because the register \everysetupdocument is defined previously in core-ini.mkiv. Wolfgang

Luatex 0.78.2 announcement
by Taco Hoekwater 13 Jan '14

13 Jan '14

Hi, I have just uploaded the archives for a new luatex release, 0.78.2. This release merges some experimental branches, and fixes a few of the outstanding bugs. Changes: * Extended lua fontloader's info() function to include data from the 'pfminfo' and 'names' structure. * Removed a recent extension in the lua fontloader library that made loading fonts with lots of glyphs slow (ArialUnicoce.ttf). Note: the extension made sure that there were no duplicate glyph names in the font after loading. * Restored --recorder output for lua files (dofile/loadfile/io.open) * One-at-a-time pattern adding from lua used to require enormous amounts of memory * luatex's fontloader.to_table() no longer reports 'altuni' table information for alternates that are solely driven by the font encoding. This fixes loading time issues for fonts that fill encodings by copying a single glyph many times, like e.g. LastResort.ttf from Apple. * The datestamp no longer appears in any banners. The associated \luatexdatestamp primitive is deprecated and will be removed in 0.80.0. * Synchronization with the TeXLive sources updated the following libraries: * cairo is now 1.12.16 * pixman is now 0.32.4 * lua is now 5.2.3 * zlib is now 1.2.8 * poppler is now 0.25.0 * That same TL synchronization also fixes these issues: * Always write "\nendstream" to the PDF for PDF/A-1b compliance. * Large file support (>4GB) in Lua * Big images could overflow on systems where sizeof(long)=4. * In writing CID CFF fonts to the PDF, and end_dict() was missing. * Unknown 'post' table versions (found in some broken ttf/otf fonts) are now treated as-if they specified version 3.0. * Fix crashes on 32-bit systems caused by bad C header inclusion order * Handle '--luac' and '--luaconly' properly * luatex is now released under GPLv2+, not just GPLv2. * luatex can now find .ofm metric files even if the extension is not given explicitly. * node.unset_attribute() was broken in 0.78.0 * The UTF-8 commandline patch from 0.78.0 for Win32 was removed again (did not work properly) The archives can be downloaded from supelec as usual: https://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co --username anonsvn --password anonsvn \ https://foundry.supelec.fr/svn/luatex/tags/beta-0.78.2 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.78.0 announcement
by Taco Hoekwater 31 Dec '13

31 Dec '13

Hi, I have just uploaded the archives for a new luatex release, 0.78.0. This release merges some experimental branches, and fixes a few of the outstanding bugs. Changes: * Instead of using expanded fonts, just calculate the expanded width of glyphs where needed, and carry expand info in the glyph nodes (all based on Hans' suggestions). All font expansion functions are disabled and most are removed. * New, faster (but limited) direct node access from lua, see the manual for details * Support for Apple Advanced Typography (AAT) information in fonts is dropped * Extended build script for mingw/msys (includes 64-bit support) * Various patches from/via Akira Kakuta for better Win32 integration * Fixes for some bugs in de pdfscanner library (mostly related to inline images) * Maximum hyphenated word length is now 64Kb characters. * Various patches from Khaled Hosny and Luigi Scarso for the luafontloader subsystem * Fix for a crash when re-dumping formats * Fix for a Selene unicode library bug where some characters in UTF-8 were incorrectly flagged as having the 'Space' property * Some smaller fixes The archives can be downloaded from supelec as usual: https://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co --username anonsvn --password anonsvn \ https://foundry.supelec.fr/svn/luatex/tags/beta-0.78.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, and a happy new year!
