MPlib and btex...etex
by Graham Douglas 02 May '10

02 May '10

Hi All I have a quick question about the behaviour of btex...etex. The code below works perfectly until I include any mp code which make use of btex...etex. I keep getting errors like this: >> mapmax.mp >> mapmax.mpx ! Unable to make mpx file. l.383 l abel.bot(btex $\reals$ etex, q+(0,-b)); I am running a slightly older version of LuaTeX on Windows Vista Version beta-0.53.0-2010032719 I am NOT using ConTeXt but simply using a version of Plain. Just for the record I do all MetaPost PS --> PDF with a call to GhostScript via a Lua binding. I think that in the "old days" all the btex/etex stuff was handled by a set of calls to an external program which processed the DVI -- makempx or something like that?? Can anyone tell me how MPlib now handles btex...etex so that I can try to figure out why it might be failing. I'm not sure but it may be that some calls to making temporary files are failing, but that's just a guess. Any insights into the low level btex...etex machinery would be great. Many thanks to all and best wishes Graham ===== ========================================== Test MP code ========================================== local function finder(name, mode, ftype) local found if mode=="w" then found = name else found = kpse.find_file(name,ftype) end if found then print("MPlib finder: " .. name ..

Luatex 0.60.1 announcement
by Taco Hoekwater 28 Apr '10

28 Apr '10

Hi, I have just uploaded the archives for a new luatex release, 0.60.1, a bugfix release for the 0.60 branch. New features: * renamed node.skipable() to node.skippable(). * More git discovery patches in getluatexsvnversion.sh. * Added --warnings=[no|min|yes|max|all] option to build.sh. * While cross-compiling, build.sh now adds an extra linker switch to allow win32 exes to use 3G instead of 2G of virtual memory. Bugfixes: * os.exec() & os.spawn() handled the environment differently from os.execute() on Win32 (patch from Tomek) * Builds with --enable-ipc were broken. * Assigning and acquiring \fontdimen s from TeX code was broken. * An initial attempt at fixing bug #372 (\predisplaydirection). * An attempt to fix \eqno/\leqno placements in mixed direction \mathdir/\textdir. * Our local xpdf patch is reverted, it is not needed any more. * The os.selfdir variable was not documented, as well as broken on WIN32. * Fix "\input tikz hello \bye" bug, plus fix one sign error. * Fix handling of lua script files with UNC names. 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-0.60.1 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
