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

Luatex 0.60.0 announcement
by Taco Hoekwater 05 Apr '10

05 Apr '10

Hi, I have just uploaded the archives for a new luatex release, 0.60.0. This release starts a new chain of stable beta's, and will be the version included in this year's TeXLive. New features: * os.name now knows about CYGWIN (from Elie Roux) * Internal handling of direction specifiers is faster now. * Each glyph node now has three new virtual read-only fields: width, height, and depth (values in scaled points, of course) * There are new functions node.protrusion_skipable() and tex.badness() (useful for paragraph breaking in lua) * Also new: tex.linebreak(). See the manual for details. * All lua errors now report file and line numbers to aid in debugging. * Import of metapost 1.211. * pdf.pdfcatalog will be replaced soon by the new pdf.catalog pdf.pdfinfo will be replaced soon by the new pdf.info pdf.pdfnames will be replaced soon by the new pdf.names pdf.pdftrailer will be replaced soon by the new pdf.trailer * pdf.pdfmapfile and pdf.pdfmapline are replaced by the new pdf.mapfile() and pdf.mapline() functions. (a function interface fits these parameters better because they never return anything). * New read-write lua variables: pdf.pageattributes, pdf.pageresources, pdf.pagesresources * getluatexsvnversion.sh now correctly detects git-svn and still manages to find a valid SVN revision number (from Patrick Gundlach) * Many of the source files have been converted to CWEB. Bug fixes: * GNU libtool is now used to solve the various technical issues with dynamic loading of lua modules. * Error detection in scan_integer_part was wrong due to missing initialization of OK_so_far (spotted by Javier Mugica) * Synctex was broken in 0.51-0.52. * \lastlinefit was broken since ... well, nearly forever. * Reading of binary files with length zero was broken. * Trapping of unitialized rules (this was for sloppily created rule nodes from lua) * pdf.immediateobj('streamfile') was broken on 64-bit platforms. * tex.linebreak did not take the given left and right skip, but instead used the current TeX-side values (bug #356). * the found 'MAKE' command in build.sh is now fed into configure to fix problems with that not finding GNU make even when it is actually installed. * dofile(<nil>) and loadfile(<nil>) in batch mode now give an error and continue instead of pointlessly waiting for user input. * Reverted commit #3417 (the buildpage experiment) as it causes bad things to happen when items are waiting during page breaks. * Overrule loaders[4] in --safer mode, make require() behave closer to normal lua 5.1, and add some nicer error messages (based on an email and patches from Manuel Pegourie-Gonnard) * Added an extra sanity check for GDEF loading in luafontloader, based on a crash caused by Linux' AkaashNormal.ttf.

How up to date char-def.lua is?
by Khaled Hosny 23 Mar '10

23 Mar '10

Since Unicode keeps adding new characters and scripts with each release (and some times altering the properties of existing characters), I was wondering how up to date char-def.lua is, in particular on which version of Unicode data was it based and how frequently it is synced with Unicode (if at all). It would be even nice to have an mtx script to update the database when needed. Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer

Hi Mojca, since a few days ago the minimals appear to rsync the cache folder, too... is this intended? Oliver

Luatex 0.52.0 announcement
by Taco Hoekwater 20 Mar '10

20 Mar '10

Hi, I have just uploaded the archives for a new luatex release, 0.52.0. New features: * Various small manual improvements. * A better version of getluatexsvnversion.sh, from Tomek. * node.copy_list() now allows the second (optional) argument to be nil. * An import of the current state of the texlive repository (kpathsea and build system). Bug fixes: * An attempt fix for bug #345 (math kerning is not perfect): when the current math font is a new math font, check against \catcode <cur_c> == 11 to suppress the italic correction, instead of looking at the value of space(<cur_f>). * There is a new <tfmtable> key: 'units_per_em' (defaults to 0). This is part of a fix for bug #200 (Problem with CFF fonts having em-size other than 1000): there is a special correction to the embedded cff font itself and the font scale if the font to be output is opentype or type1 in unicode encoding and the 'units_per_em differs' from zero. <tfmtable>.units_per_em has to be passed back to luatex from the lua font loading code for this to work. * A fix for bug #314 (problem with pk file). * lua code can no longer change the internal preallocated glue_spec nodes (as that resulted in weird spacing bugs). For this, glue_specs now have a new field: 'writable'. If that field is false, a copy has to be made of the glue_spec instead of doing an assignment to it. * Setting of \textdir inside the output routine could trash output on following pages due to a lingering internal variable. * \pdfthread crashed because the arguments were handled in reverse order.

Hi, I added \defineinterlinespace ... needs a bit of checking \setupinterlinespace[list] \setupinterlinespace[assignments] \defineinterlinespace[defined_name][assignments] \setupinterlinespace [defined_name][assignments] \setupinterlinespace[defined_name] the potential is there to do \defineinterlinespace[defined_name][another_name][assignments] as we use the parent mechanism I hope i didn't break too much.

12 Mar '10

Hi, I have just uploaded the archives for a new luatex release, 0.51.0. New features: * Various small manual improvements. * The backend message "cannot open Type 1 font file for reading" now reports which Type1 font it was looking for. * Fontforge clears some font names at loading time that will be refilled in at font generation time, but the fontloader should not do that. Patch from Khaled Hosny. * New synctex code imported from TeXLive. * luamd5/md5.h is renamed to luamd5/luamd5.h to avoid confusion. * Embedded mplib is now 1.209. * Some experimental tweaking of buildpage_filter, see the manual for details. * Luatex now detects kfreebsd (from Alan Braslau) * The new lua function tex.sp() converts a string to a number representing scaled points. * There is now support for revision numbers in the banner and stats library again. * The command line help and manual documentation page is extended. * node.hpack() now also accepts "cal_expand_ratio" and "subst_ex_font" modifiers. * node.hpack() and node.vpack() now give back the badness of the box as second return value. * node.copy_list() now allows a second (stop) argument, this stopper is not copied. * new lua functions in lfs: lfs.readlink() and lfs.shortname(). * new lua function tex.tprint() that can combine multiple catcode regime prints in one function call. * new lua sub-table: tex.nest[] (read/write access to the semantic nest state). * New lua functions in kpse: kpse.lookup() and kpse.version(). See the manual for more details. * New lua function tex.shipout().

Versioning system for modules
by Patrick Gundlach 11 Mar '10

11 Mar '10

Hi, esp. Mojca, what are the requirements for version controlled systems? What are the usecases? It is hard to decide which versioning system to use without knowing who needs it and when. Thanks! Patr... (can't type the rest of my name right now, too complicated)

OpenType Optical Bounds 'opbd' feature
by Khaled Hosny 25 Feb '10

25 Feb '10

Is 'opbd' feature supported? According to the spec[1] this feature is used to define what I think is equivalent to the protrusion values used for optical alignment of the glyphs. I grepped the sources and there seem no be special handling of it, I don't have fonts that use this feature (I didn't look for one) but I'm planning to use it in my fonts and thought I'd check if ConTeXt support it first. This Typophile thread[2] might be interesting too. If fonts are needed I can check for free fonts that implement this, or prepare a font for testing.
