luatex beta 0.40.5
by Taco Hoekwater 10 Jun '09

10 Jun '09

Hi, I have just uploaded luatex 0.40.5 to the foundry server, and have committed the source code to texlive. What's new: * One of the internal print functions accidentally encoded its argument string to UTF-8 even though it was already UTF-8. * Some of the log and terminal UTF-8 output was gibberish. 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-0.40.5 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

removing BibTeX auxiliary files with --purgeall
by Oliver Buerschaper 10 Jun '09

10 Jun '09

Hello Hans and Taco, may I also add the request that temporary files created by BibTeX are deleted automatically by --purgeall? That is, *.blg *.aux It'll probably be wise to keep the *.bbl file :-) Although it is created automatically by the BibTeX run I need to tweak it manually at times ... Best wishes, Oliver P.S. I cannot test this with MkIV at the moment but MkII doesn't delete those files for sure ...

MetaPost 1.203 announcement
by Taco Hoekwater 09 Jun '09

09 Jun '09

The MetaPost team is happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.203 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ This release will also be available from CTAN soon, and it will be included in the next TeXLive. The source package should compile normally on all systems that are capable of compiling a modern web2c-based TeX distribution. 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 1.203: ---------------------------------------------------------------------- * Building version 1.202 for source required X11 headers to be installed. * Another infinite recursion trap added, now for erroneous vardefs with suffixes (reported by Nicola Vitacolonna). * Fix infinite loop recursion on integer overflow (reported by Nicola Vitacolonna, fix based on a hint from Dan Luecking). * In version 1.202, setting "job_name" from lua code caused a crash. * The "filename" field on the lua figure object in 1.202 was just the extension, instead of the whole file name. ---------------------------------------------------------------------- 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.

use of \phantombox doesn't match its definition
by Sanjoy Mahajan 06 Jun '09

06 Jun '09

In trying to install the latest context on my system, I installed texlive 2008, then the 2009.06.04 context, and rebuilt the formats. Using texlive 2008 solved my problems with the Palatino fonts not being found (compared to when I was using the latest context with texlive 2007). However, the following file fails on my laptop, and on the live Context (also 2009.06.04, texlive 2008): \newbox\phantombox \def\lowest#1{\setbox\phantombox=\vbox{\vphantom{$\displaystyle{#1}$}}} \def\support{\copy\phantombox} \starttext \startformula \lowest{Q} \underbrace{\support Q}_{dx} \stopformula \stoptext The error is: ! Use of \phantombox doesn't match its definition. \lowest #1->\setbox \phantombox = \vbox {\vphantom {$\displaystyle {#1}$}} l.8 \lowest{Q} Changing all uses of \phantombox to \phantomboxff fixes the problem, so maybe there's a name clash, but I couldn't find it in the context source code. -Sanjoy

luatex beta 0.40.2
by Taco Hoekwater 03 Jun '09

03 Jun '09

Hi, I have just uploaded luatex 0.40.2 to the foundry server, and have committed the source code to texlive. What's new: * Fix for a compilation warning under Cygwin. * A complicated bugfix by Hartmut for a rounding problem in the VF loading that resulted in 'character width mismatch in font XY.vf ignored' messages at large load sizes * The embedded MPlib is now 1.202. * The post_page_number callback was accidentally run when shipping out xforms as well as during actual pages. * When a math accent char doesn't have a bot_accent placer, luatex now uses the top_accent placer, if present. * A crash caused by \Uroot .. {<list>}{...} is fixed * A portability fix for solaris 8 sparc using sun studio compiler, and one for glibc > 2.9.90 * luatex -ini now sets the \catcode of the BOM character to ignore (9) * Kpathsea is updated from TeXLive, giving four extra types of searchable files: 'font feature files','cid maps','mlbib', and 'mlbst'. * libpng is now 1.2.36 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-0.40.2 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
