I am happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.901 ---------------------------------------------------------------------- This is still the release for TeX Live 2014, just adding some bug fixes. 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/1.901 The password is anonsvn ---------------------------------------------------------------------- What is new in MetaPost version 1.901: ---------------------------------------------------------------------- * Fixed a bug in 'decimal' mode that affected (among other things) the directionpoint and bbox calculations. * Fixed a bug in 'decimal' mode calculation of sine / cosine that affected the precision of the answer in situations where 'numberprecision' was less than 34. * Updated the number parsing in 'decimal' mode to detect 'too precise' input and optionally generate an error in that case (depends on 'warningcheck') * Fixed a bug in the svg output where it could crash in 'decimal' mode. * Fixed a bug in the png output where it could get confused if there was more than one text label * Fixed a bug in the png output for stroked paths Have fun!

Luatex 0.79.0 announcement
by Taco Hoekwater 28 Mar '14

28 Mar '14

Hi, I have just uploaded the archives for a new luatex release, 0.79.0. This fixes a few of the outstanding bugs, and is the version that will be included in TeXLive 2014. Changes: * The luafontloader now returns 'tsidebearing' glyph values for OT/TT fonts, if applicable. * new lua variables: stats.luatex_hashtype, stats.luatex_hashchars, stats.lastluaerrorstring; the luajittex string hash method is now lua 5.1 compliant which gives better results for similar strings * new lua functions: tex.init_rand(), tex.uniform_rand(), tex.normal_rand(), tex.lua_math_randomseed(), tex.lua_math_random(), tex.show_context(); these helpers make luatex and luajittex compatible * In the lua node interface, there were often issues with rubbish in (especially) 'prev' fields because luatex itself never looks at those values. This is now cleaned up to prevent weird stuff happening inside lua node processing code. * pdf.pageattributes, pdf.pagesattributes, pdf.info, pdf.catalog, pdf.names and pdf.trailer now behave consistent and can be used to add these properties at the lua end in addition to their \pdf* counterparts atthe tex end; there are now pdf.get* and pdf.set* commands for them too (in future versions the old ways can become obsolete) * new accessors pdf.geth, pdfgetv, pdfgetpos, getgetmatrix as well as pdfhasmatrix helpers (in future versions the direct pdf.h and pdf.v accessor can become obsolete) * the pdf.pdf* variables have been removed (they were already obsolete for some years) * a new properties mechanism for associating lua tables with nodes that get cleaned up when nodes a freed (see manual for details) * several improvements to the way temporary (backend) data is stored at the lua end (better protection, more consistent) * a 'l' type for user nodes that holds a lua variable (can be set at the lua end) * if a late lua node is set at the lua end the string value can be a function as well which is then executed during serialization to the backend stream * Various small speedups * Various smallish fixes to the node direct interface * LPeg is now at version 0.12 * Some small fixes to the CFF (font) parsing * Font file inclusion reporting messages on the terminal now comply to the texconfig.trace_file_names setting * Removed some of the additional luafontloader.info() return information that was added in 0.78.2, but could not work properly. * new primitive \luafunction (see manual), with associated lua.get_functions_table() function * lua error message reporting has been altered a bit to make the distinction between \directlua and other lua source code sources clearer * Additional pdf document data functionality in the 'pdf' table has been cleaned up internally * Additional pdf destination names can now be set via lua. * New callbacks: finish_pdfpage, show_error_message, show_lua_error_hook, start_file, stop_file * Handling of \tracinglostchars is fixed * Embedded metapost library version is now 1.900 * luajittex is now included in the distribution. One can use buildjit.sh to build both luatex and luajittex, where supported by the platform * Synchronization with the TeXLive sources updated the following libraries: * libpng is now 1.6.10 * poppler is now 0.25.2 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-0.79.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

MetaPost 1.890 announcement
by Taco Hoekwater 11 Mar '14

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

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.
