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

Luatex 0.50.0 announcement
by Taco Hoekwater 25 Dec '09

25 Dec '09

Hi, I have just uploaded the archives for a new luatex release, 0.50.0. This release starts a new chain of stable beta's. New features: * Fonts now listen also to the 'extend' key in the lua font metrics table, and the processing for this is done via de pdf text matrix instead of via the font matrix, which means it now works for all font types. * The embedded Metapost library is now at version 1.209. Dropped features: * It is no longer possible for fonts from embedded pdf files to be replaced by / merged with the document fonts of the enveloping pdf. This regression may be temporary, depending on how the rewritten font backend will look after beta 0.60. Bug fixes: * Use of \middle confused the \mathstyle operation. * \pdfcolorstack handling was broken. * node.unset_attribute() had a bug whereby it inverted the requested result in some cases (the node on which the unset was called was sometimes the only node at the current level that *kept* the attribute). * During font expansion, the internal font copy had one character information object less than the original, resulting in the disappearance of a glyph in some fonts when font expansion was active. * Placement of operator scripts of OT MATH fonts is adjusted to be conformant with Word's logic where the italic correction is only used to tuck in the subscript and for nothing else. * luafontloader.open() no longer writes directly to stderr in case of internal font errors. * Any <pdf_refobj_node>.objnum could not be assigned to. * The lua 'pdf' table could not be assigned to. * The lua 'md5' library was returning incorrect results on 64-bit architectures. * Luatex now compiles on GNU Hurd systems. * Fix segfault when embedding stream file object (these backend segfaults were a side-effect of the string pool patches). 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-0.50.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.47.0 announcement
by Taco Hoekwater 18 Dec '09

18 Dec '09

Hi, I have just uploaded the archives for a new luatex release, 0.47.0. This will be the last beta before the next major release (0.50), so please test this version as thoroughly as you can. New features: * New read-write lua variables pdf.pdfcatalog, pdf.pdfnames, pdf.pdfinfo, pdf.pdftrailer * The horizontal mode nodes that are added to lines during line breaking now inherit the attributes from the first and last node inside the created line. * The new function pdf.registerannot(<number>) registers an annotation object number to be included in the current page's /Annots list. * The variables <metrics>.Mathconstants.FractionDelimiterSize and <metrics>.Mathconstants.FractionDelimiterDisplayStyleSize are added to the font table. This allows proper setting of the size parameters for TeX's ...withdelims math primitives. * The internal representation of the string pool is reorganized (the pool of string characters is now allocated dynamically), and as a side-effect the lua variable status.init_pool_ptr is deprecated and will be removed in a later version. Also, status.pool_ptr now simply returns the current number of bytes in use for string characters. * There are new lua variables pdf.pdfmapline and pdf.pdfmapfile (write-only strings that mimic \pdfmapline and \pdfmapfile). * \pdfobj data and attribute are now stored as C strings instead of as token lists (this should speed up cases with a lot of data). * Artificially slanted fonts now work via the pdf text matrix (instead of adjusting the actual font) so that it now also works for non-Type1 fonts. The lua <metrics>.slant font key is now obeyed in all cases. * The lua function font.id(<string>) returns the internal font id number belonging to a control sequence name. * Pdf image inclusion is optimized such that objects from an external pdf will now be included only once even if they are referenced from multiple inclusions. Bug fixes: * Protrusion for non-TLT documents did not work properly for the hyphenation character. * \lastbox could not remove the paragraph indent box for non-TLT documents. * Pdf images (\pdfximage) are no longer kept open during the whole run, but closed and reopened. An error is raised if the file has changed between \pdfximage and \pdfrefximage. This prevents the 'too many open files' error when lots of images are included. * On Win32 Pdf image files are locked during the time that it is open, to prevent unnoticed file changes by external sources. * Compilation now again works on FreeBSD. * Format sharing between 32-bit and 64-bit architectures was broken. * Unsetting attributes from lua could sometimes result in the unset state persisting beyond the current group level. * If something went wrong in the scanning of pdf action items, the error message reported the current primitive name incorrectly. * Luatex would crash on non-existant pdfs that were referenced from map file entries. 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-0.47.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Luatex 0.46.0 announcement
by Taco Hoekwater 12 Dec '09

12 Dec '09

Hi, I have just uploaded the archives for a new luatex release, 0.46.0. There are two important reason for this release: * It fixes an xform bug that is quite serious as it produces invalid pdf files (see below) * There is now experimental support for loading external .dll/.so files for lua extension modules. Copied from a message I sent to the dev-luatex list a few days ago: > I have committed an experimental patch that > enables dynamic loading for external compiled libraries unless --safer > is given on the command-line. > > It is experimental because: > > * it assumes that all architectures except windows will be happy with > using dlopen (windows has its own code which does not need compile- > time support, but you have to have an installed lua51.dll from e.g. > http://luabinaries.luaforge.net ). > > * I made only minimal changes to kpathsea. > > * there may be lua libraries out there that fail horribly. > > As with pure lua require() files, luatex will only use kpathsea if the > library is initialized already. > > kpathsea changes in detail: > > I added the kpse_clua_format identifier that searches for files with > extension .dll and .so. The texmf.cnf setting for this variable is > CLUAINPUTS, and by default it has this value: > > CLUAINPUTS=.:$SELFAUTOLOC/lib/{$progname,$engine,}/lua// > > This is the best I could do on short notice: the architecture has to > be in the path somewhere, and the fastest way to do that is to search > below the binary directory only. > > One level up (lib parallel to bin) would have been nicer, as the > context minimals have arch and bin swapped (texmf-linux/bin as opposed > to bin/i386-linux) but that would not have worked in texlive. If you know how to compile dynamic libraries on your platform, a good library to play with is Lua BitOp, http://bitop.luajit.org/ (single C source file and comes with a nice test lua script). And here is the normal list of features and bugfixes in 0.46.0 -------------------------------------------------------------- New features: * The build.sh script now has better support for new MacOSX-es (patch from Mojca). * Luatex now has experimental support for dynamic loading of external compiled lua libraries. Building luatex and loading external .so/.dll files is reported to work on Windows, linux and osx, other platforms are still unknown. * pdf.obj{type="stream"} no longer converts its argument to and from a tokenlist. This allows the use of binary data in the "string" argument. Such data does still have to hidden from the normal file parser by putting the code in a dofile() or by using string.char(), though. Bug fixes: * Luatex 0.45.0 was not able to find truetype nor opentype fonts if there were no callbacks defined (patch from Pawel). * 0.45.0 printed the user input instead of the full pathname for \input-ed tex files. * The TFM reader now rejects fonts with tfm names that are longer than 255 characters because such font names cannot be stored in a DVI file. * The combination of \immediate\pdfxform followed by a later \pdfrefxform could cause broken pdf output files because the box used for the form could have been freed and even reused already at that moment in time, sometimes resulting in an invalid transformation matrix. * The placement of super- and subscripts for displaystyle \int's in CambriaMath is now better than before. It still needs a tweak to the metrics though: in the current version, the italic correction has to be substracted from the width of the integral sign to get correct placement (context mkiv does this). to be continued ...

bib: space gobbled after \cite
by Sanjoy Mahajan 30 Nov '09

30 Nov '09

With recent versions of ConTeXt, spaces after \cite[Author:1977] are getting eaten. I'm pretty sure that did not happen with versions from a while ago, but the archives suggest that it happened a long while ago: <http://www.mail-archive.com/ntg-context@let.uu.nl/msg00062.html> The minimal test file: ============================================= \usemodule[bib] \setupbibtex[database=statement, sort=author] \starttext Polya said \cite[Polya:1966] in 1966: "finished mathematics consists of proofs, but mathematics in the making consists of guesses." \blank \placepublications \stoptext ============================================== The first line ends up "Polya said (Polya, 1966)in 1966..." with no space after the close paren. (This is with 2009.10.27 16:35 MKII on top of TL 2009 from Debian.) Here is statement.bib to complete the example: @Misc{Polya:1966, author = {George Polya}, title = {Let us teach guessing}, howpublished = {VHS}, year = {1966}, publisher = {Mathematical Association of America}, } -Sanjoy `Until lions have their historians, tales of the hunt shall always glorify the hunters.' --African Proverb

bib: triple dash in article title causes problems (minimal example)
by Sanjoy Mahajan 24 Nov '09

24 Nov '09

To continue my earlier message about "--" in bibtex titles: I replaced the "--" with a triple dash "---" but still had problems unless I used \enableregime[utf]. Even then I had problems if I was also using products and projects, where \enableregime[utf] seemed to have no effect for the bibliography. Attached is a minimal set of files as a .tgz. Unpack and do 'cd test'; then 'make'. The resulting PDF, at least on my system (TL 2009 Debian + context 2009.10.27) has the accent characters instead of the em-dash. A small-size png image of it is attached. -Sanjoy `Until lions have their historians, tales of the hunt shall always glorify the hunters.' --African Proverb

bib: article title with -- comes out mangled
by Sanjoy Mahajan 22 Nov '09

22 Nov '09

This test file has a mangled article title where the "--" was located in the bibtex entry (a few accented characters show up). Commenting in the \enableregime removes the accented characters, but now there's a mix of different dashes almost joined together. % \enableregime[utf] \usemodule[bib] \setupbibtex[database=project] \starttext Look up the Shannon--Nyquist sampling theorem \cite[Jerri:1977]. \blank[3*big] \placepublications[criterium=all] \stoptext Here is the bibtex file @Article{Jerri:1977, author = {A. J. Jerri}, title = {The {S}hannon sampling theorem —- {I}ts various extensions and applications: A tutorial review}, journal = {Proceedings of the IEEE}, year = 1977, volume = 65, number = 11, pages = {1565--1596}} (A workaround is to make the " -- " into "---", which is what it should have been anyway.) This is with context 2009.10.27 16:35 MKII in the Debian TL2009 packages. I also see the problem with 2009.11.20 on top of vanilla TL2009 or vanilla TL2008. -Sanjoy
