Luatex 0.63.0 announcement
by Taco Hoekwater 09 Sep '10

09 Sep '10

Hi, I have just uploaded the archives for a new luatex release, 0.63.0. This is a development release. News: * Drop tex.ht[], tex.wd[], tex.dp[]. * Drop OCP support (and associated primitives). * Add tex.catcode[], tex.lccode[], tex.sfcode[], tex.uccode[], tex.mathcode[] and tex.delcode[] and associated functions. * Add CIDset tables to the output pdf where appropriate. * Added a 'string' field to late_lua nodes on the lua side. This field does not convert the assigned string to a tokenlist. * The result of fontloader.open() now has some virtual accessors (as well as fontloader.to_table). * There is now a `short reference' in the manual folder (functionref.pdf) Bugfixes: * Fix a crash on an empty font (bugreport #468). * Fix a crash for extremely long pattern arguments. * Fix a crash on bad virtual character arguments in lua. * Fix hyphenation exceptions. * Prevent linebreak between initial local_par paragraph whatsit and a following skip (bugreport #437). * Fix placement of scripts on textstyle big operators in MATH fonts (bugreport #466). * Fix a crash on the return value of MPlib's 'postscript' operation on images. * Fix a crash on \leftghost & \rightghost in math mode. 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-0.63.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.62.0 announcement
by Taco Hoekwater 23 Aug '10

23 Aug '10

Hi, I have just uploaded the archives for a new luatex release, 0.62.0. This is a development release, but it also fixes some nasty bugs in beta 0.61.0, so if you use that right now, upgrading is recommended. News: * LuaTeX now uses libpoppler (0.12.4) instead of xpdf. * All backend functions now report what file they were searching for whenever a file cannot be found. * Input-ed lua files are now mentioned in the fls file if the --recorder switch is specified on the command line. * Paragraph indentation hlist nodes and hlist and vlist nodes generated by alignment rows and cells now have a subtype (3 for indent box, 4 for rows/columns, 5 for cells). * The 'epdf' lib is in active development and still growing. * The 'fontforge' table is finally removed (was deprecated since 0.40). Bugfixes: * A new mplib import fixes two bad bugs in mplib: - string equality test was wrong - type declarations could delete pre-existing variables * PNG images with transparency could create random size differences in the generated PDF. * In some special cases, font expansion could cause wrong spacing in the generated PDF. * \letterspacefont was broken since a very long time. * The node subtype of the \leftskip and \rightskip glues was wrong. * Some memory leaks have been removed. * Various manual fixes. 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-0.62.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

by Taco Hoekwater 28 Jul '10

28 Jul '10

Hi, I have just uploaded the archives for a new luatex release, 0.61.0, the first of the betas toward 0.70.0. New features: * New lua library 'epdf' for introspection of PDF inclusions, see the manual for details. * Mplib version 1.502 is now included (which is still beta, so be careful). * new "finish_pdffile" and "pre_dump" callbacks. * new function pdf.pageref() * In the lua 'tex' library: assignment to internal glue parameters is now allowed. * New lua function tex.error(). Bugfixes: * Fix for crashes on fonts with bad Panose values. * Fix for a box placement bug that could sometimes cause text to overlap. * Fix for a few small PDF/A1-a compatibility bugs. * Fix \letterspacefont. * Fix \Ustopdisplaymath in combination with aligned displays. * In math delimiters, the last of a chain of predefined sizes was always ignored if there were also extensible parts. 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-0.61.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

MetaPost 1.502 (beta version)
by Taco Hoekwater 27 Jul '10

27 Jul '10

I am happy to announce a new beta release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.502 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ This is a beta release following the major internal rewrite done for 1.500. After quite a lot of community feedback on the previous two releases (a big thank you! goes to the testers) most of the bugs should be gone now, but just in case: please be careful and check the output of this metapost version when it is used in production work. The win32 binary is intended for texlive or a similar web2c-based installation, this executable will *not* work for miktex. Of course, we welcome any comments (either good or bad) that you may have. Simply replying to this message is fine, but see the bottom of the message for a more formal way to report bugs and feature requests. ---------------------------------------------------------------------- What is new in MetaPost version 1.502: ---------------------------------------------------------------------- * New build system and kpathsea imported from TeX Live. * Many small bugfixes to 1.501. ---------------------------------------------------------------------- What is new in MetaPost version 1.501: ---------------------------------------------------------------------- * The maximum number of variable instances has increased from approx. 33 million (2^25-1) to 2 billion (2^31-1). * New build system and kpathsea imported from TeX Live. * Many small bugfixes to 1.500. ---------------------------------------------------------------------- What is new in MetaPost version 1.500: ---------------------------------------------------------------------- * Actual memory dump files do not exist any more. --mem=<MEM> and all other methods of supplying a MEM file are now interpreted somewhat like this pseudo-metapost-code: begingroup; let dump = end; input MEM[.mp]; endgroup; this process is supposed to be transparent besides the facto that there is some extra terminal output and logging. * All memory is now allocated and freed dynamically. There are only two remaining overflow errors(1): "expansion depth" : this is a guard against infinite recursion, the value is 10000. "sizes per font" : this is maxed out for data-structure reasons, the value is 32767. from texmf.cnf, now only the "error_line", "half_error_line" and "print_line settings" are used. (1) but now you can reach the operating system limits, of course. * As this is an alpha release containing lots and lots of new code, MetaPost starts up with the internal equivalent of 'loggingall;' in effect. This results in log files that can help in debugging. * Expect bugs and (minor) memory leaks. ---------------------------------------------------------------------- Legal notice / license / bug reports ---------------------------------------------------------------------- MetaPost is a system for producing graphics developed by John Hobby at AT&T, based on Donald Knuth's Metafont.

Checksum of original font files stored in the cache?
by Oliver Buerschaper 19 Jun '10

19 Jun '10

Dear wise guys, the other day I found myself caught in a trap that might be a frequent source of puzzlement for the casual ConTeXt user :-) I had replaced an OpenType font in the usual OS directory by a new version. Typesetting documents using that font produced surprising results... the PDF files were merrily messed up. I reckon I didn't pay attention to the interplay between font files and the LuaTeX cache... apparently ConTeXt was using the outdated font cache data together with the new font file since a few days later the problem was resolved once I had to regenerate the cache for other reasons. Only then did I notice I had also cured this font problem. Do you think it would be a good idea to store a checksum of the actual font file used while generating the cache? Best, Oliver
