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. 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-0.52.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

interlinespace
by Hans Hagen 12 Mar '10

12 Mar '10

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.

Luatex 0.51.0 announcement
by Taco Hoekwater 12 Mar '10

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(). Bug fixes: * There problems in the pdf output for Type3 (pk) fonts. * Fix a bug that allowed bad commandline quoting. * Fix a bug that sometimes caused crashes when \pdfprotrudechars. * The build script now exports CONFIG_SHELL to avoid problems with /bin/dash. * The was a bug in the generated /Image /ProcSet. * status.font_bytes reported the wrong value. * Lots of compiler warnings are removed (thanks Javier Mugica). * Patch to fontloader.info() to accept filenames with embedded parentheses. * Fix a \write error with docstrip package. * Fixed a crash on AdobeMyungjoStd-Medium.otf. * Fix coco stack overflows, needed for lpeg. * \pdfcompresslevel wasn't initialized for early immediate objects. * Fix for slanted fonts when HZ was on (slant angle was multiplied). * When concatenating content streams, put a space between them. * Allow pfb lines to end with \r as well as \n (for msam10.pfb). * Fix the internal string->scaled point conversion in the lua interface. * Memory leaks in the fontloader removed, thanks to patches from Elie Roux. * Fix a crash caused by the combination of coroutines and font.each(). Removed features: * Support for Type3 .pgc files (nobody used them).

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.

Re: [dev-context] Mac installation package
by Jörg Hecke 24 Feb '10

24 Feb '10

Hi, > I'd be glad if as many people as possible on this list would give it a > try and report back their experience. Once the package turns out to > work as intended I'll make it available to the wider public. I gave it a try and it works quite nice. Since I am currently using Context/MKII (Installed via the TexLive 2008 distribution) for my documents, your solution would provide even me with a fairly simple method to use the current minimals installation and to try out MKIV. Even switching between "Context-2009-06-11-beta", "gwTeX" and "TeXLive-2008" by using the TeX Distribution system preference panel works. A Testdocument works with "TeXLive-2008" (texexec produktvorschlag.tex) as well as with your installation "Context-2009-06-11-beta" (context produktvorschlag.tex) Another Question though: ------------------------ Would it be possible to install (optionally perhaps) third party modules like t-letter and t-simplefonts also? I would like to try to use Myriad Pro and using simplefonts seems to be the simplest solution for that (at least for me when reading through the wiki. I don't think that I am able to create typescripts, support files for TeX etc.). Or can I install these third party modules by myself in your "Context-2009-06-11-beta" tree (downloading first-setup.sh in your folder "/usr/local/context/2009-06-11-beta" failed for me, perhaps due to missing rights?)? Many thanks for working on such a nice installer package for such a simple users as me on the Mac. Best Regards Jörg

unicode-math
by Philipp A. 12 Feb '10

12 Feb '10

hi, context in combination with luatex is quite the way to go for me, but i have one thing that i would love to see inside context: unicode-math<http://github.com/wspr/unicode-math>! the guys there are making a good job of mapping tons of unicode sequences to latex commands, so we should really profit from this project. is it possible to integrate it into context or to create a package for this purpose? i would love to write $y = x² ± 2µ ⇒ y ≠ √{α ⁄ 5}$, while still being able to write $y = x^2 \pm 2\mu \Rightarrow y \neq \frac{α \over 5}$ or any combination of the two. i would too love to participate in a project making this possible, but i don’t know how to start coding (i could only write a preprocessor in python doing this, but that would be rather a workaround than the true thing.) thanks, phil PS: the ⁄ i used is a „fraction slash“, not a simple solidus, which of course would still be rendered as solidus.

bibtex not finding style files
by Oliver Buerschaper 08 Feb '10

08 Feb '10

Hi all, does anyone have a quick suggestion on why bibtex refuses to find cont-no.bst and the other style files? I do have BSTINPUTS (and BIBINPUTS) set to BIBINPUTS = .;$TEXMF/bibtex/bib// BSTINPUTS = .;$TEXMF/bibtex/bst// which should be fine for the minimals. I can also locate the style files with luatools although that might not affect bibtex at all. So... compiling the following tex file --- \setupbibtex [database=bib-0005.bib] \starttext Default citation style: \cite[Kitaev:2003] \completepublications \stoptext --- with MkIV produces an empty .bbl file and the .blg file says --- This is BibTeX, Version 0.99c (TeX Live 2009) The top-level auxiliary file: bib-0005.aux I couldn't open style file cont-no.bst ---line 2 of file bib-0005.aux : \bibstyle{cont-no : } I'm skipping whatever remains of this command I found no style file---while reading file bib-0005.aux --- This is a complete mystery to me :-( Best, Oliver

Bug in mtx-update.lua?
by Oliver Buerschaper 31 Dec '09

31 Dec '09

Hi, it appears the variable "texroot" isn't always protected properly when fed to rsync. If "texroot" contains a space then rsync fails (see below). From what I can tell the problematic code is most probably in lines 364-369 of mtx-update.lua. This shows up at the very end: --- MTXrun | mtx update: updating luatools for osx-64: rsync -tgo --chmod=a+x /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-context/scripts/context/lua/luatools.lua /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-osx-64/bin/luatools MTXrun | run: rsync -tgo --chmod=a+x /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-context/scripts/context/lua/luatools.lua /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-osx-64/bin/luatools rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/../Local" failed: No such file or directory (2) rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/Minimals/stable/texmf-context/scripts/context/lua/luatools.lua" failed: No such file or directory (2) rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/../Local" failed: No such file or directory (2) rsync: push_dir#3 "/Users/albert/Documents/ConTeXt/Packaging/Minimals/stable/texmf-osx-64/bin" failed: No such file or directory (2) rsync error: errors selecting input/output files, dirs (code 3) at /SourceCache/rsync/rsync-37.3/rsync/main.c(580) [receiver=2.6.9] rsync: connection unexpectedly closed (8 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-37.3/rsync/io.c(452) [sender=2.6.9] MTXrun | mtx update: updating mtxrun for osx-64: rsync -tgo --chmod=a+x /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-context/scripts/context/lua/mtxrun.lua /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-osx-64/bin/mtxrun MTXrun | run: rsync -tgo --chmod=a+x /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-context/scripts/context/lua/mtxrun.lua /Users/albert/Documents/ConTeXt/Packaging/../Local Minimals/stable/texmf-osx-64/bin/mtxrun rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/../Local" failed: No such file or directory (2) rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/Minimals/stable/texmf-context/scripts/context/lua/mtxrun.lua" failed: No such file or directory (2) rsync: link_stat "/Users/albert/Documents/ConTeXt/Packaging/../Local" failed: No such file or directory (2) rsync: push_dir#3 "/Users/albert/Documents/ConTeXt/Packaging/Minimals/stable/texmf-osx-64/bin" failed: No such file or directory (2) rsync error: errors selecting input/output files, dirs (code 3) at /SourceCache/rsync/rsync-37.3/rsync/main.c(580) [receiver=2.6.9] rsync: connection unexpectedly closed (8 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-37.3/rsync/io.c(452) [sender=2.6.9] --- Can you reproduce this?

'My' context & luatex domains have moved
by Taco Hoekwater 28 Dec '09

28 Dec '09

Hi all, This regards context.aanhet.net www.metatex.org minimals.metatex.org www.luatex.org tracker.luatex.org The sites in mentioned above have moved to a new hosting server, with IP address 195.12.62.12. This new server has a better net connection and more disk space, and besides, the old server is going to be powerless in a few days anyway. Apart from the changed IP, everything else should function as before. I you notive any new weirdnesses, please drop me a message. Best wishes, Taco
