processing comma/assignmentlist
by Wolfgang Schuster 20 Jul '09

20 Jul '09

Hi, there are two macros I miss there (for the moment) in ConTeXt 1. \startprocesscommacommand/\stopprocesscommacommand equivalent to \startprocesscommalist/\stopprocesscommalist from cont-new.tex 2. A command to access the keys and labels of a assignment list at user level, e.g. \def\myassignmentlist[#1]% {\def\dosomethingwithkeyandvalue##1##2##3{... ##2 ... ##3}% ##1 = namespace (not used here) \dogetparameter\dosomethingwithkeyandvalue[...][#1]} \myassignmentlist[..,..=..,..=..] Wolfgang

Luatex 0.42.0 (a snapshot release)
by Taco Hoekwater 17 Jul '09

17 Jul '09

Hi, I have just uploaded the archives for a new luatex release, 0.42.0. NOTE: This snapshot is just for testing the new sources and the updated build process, do NOT trust this binary for production work! There is a whole lot of work done on the luatex internals since the previous beta, and just judging by the amount of work done it seems likely that there will be a few serious bugs remaining. There are two big internal changes. Both changes are invisible to the user, but definately worth mentioning: * There is no pascal (web) code in luatex at all anymore, everything is now converted into plain C and split over about 50 source files. Later, this code will be converted back to CWEB (almost all comments have been kept) but first we want to spend a few months reorganizing the code base. * The PDF backend has been reorganized a lot, and most of the global variables are not put into a single backend structure. Work in this area is not complete, but getting there. The other newsworthy changes are: * There is a new node.tail() function * lua-loaded fonts now support a 'nomath' key to speed up loading the lua table. * A bugfix in the ttf reader for the inclusion backend, and (also in the backend) support for treating ttc files by pretending they are single ttf fonts (both patches from pdftex) * Add Khaled Hosny's man page to the repository * The \pdfcompresslevel is now effectively fixed as soon as output to the pdf file has occurred. * Patched status.filename so that it (nearly) always returns a file name. * fix '\the\delcode' and disable '\the\odelcode', '\the\Udelcode', and '\the\Udelcodenum' * Handle jfifs where either xres or yres is 0 and the other res is != 0 (from pdftex) * The single-argument version of lang.hyphenate() was broken. * Get rid of the \directlua/\latelua number warning. * The Lua coroutine patch (coco) is now disabled on linux powerpc architectures (because it caused crashes) * Removed obsolete pdftex primitives: \pdfoptionalwaysusepdfpagebox \pdfoptionpdfinclusionerrorlevel \pdfforcepagebox \pdfmovechars * The loading speed of large fonts (especially ttf) via the fontloader library, and the inclusion speed for subsetting in the backend have both been improved. * The 'pdf' lua library has been enhanced with various new functions, see the manual for details. * BLT and BRT glyph position fixed. * Various fixes for synctex offsets. * Support for exotic font string encodings has been removed from the fontloader library. * The embedded MPlib is now 1.205. * libpng is now 1.2.38. 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/0.42.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

thecontextbook.com
by Adam Lindsay 14 Jul '09

14 Jul '09

Hi all, My domain "thecontextbook.com" is coming up for renewal *very* soon (the 17th). Is there anyone in the community I can transfer it to so that it might get some public usage? I'm fond of the idea of the domain, but life and competing projects have just gotten in the way of pushing that idea forward in my foreseeable future. Hope all is well, adam http://twitter.com/atl http://atl.me

Luatex beta 0.40.6
by Taco Hoekwater 25 Jun '09

25 Jun '09

Hi, I have just uploaded luatex 0.40.6 to the foundry server, and have committed the source code to texlive. What's new: * Fix two string vs. toks bugs in the lua node interface: whatsit,annot and whatsit,startlink data assignments were made directly as strings instead of being converted to tokens. * Sometimes pdf.print() could be used before the proper structures were initialized. * There was a bug in the type codes for the lua package filter callback: wrong extra info was passed to lua for the alignment and vsplit cases. * The math parameters \Umathlimitdownvgap, \Umathlimitdownbgap, and \Umathlimitdownkern have been renamed to \Umathlimitbelowbgap, \Umathlimitbelowvgap, and \Umathlimitbelowkern to be more consistent with the other parameter names. * The embedded MPlib is now 1.204. * Handling of UTF-8 hyphenation exceptions has been fixed. * There were a number of typos in the manual. 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-0.40.6 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

removing .pgf file with --purgeall
by Mojca Miklavec 15 Jun '09

15 Jun '09

Hello Hans, may I request removing \jobname.pgf when doing context/ctxtools --purgeall (in both mkii/mkiv)? That's a file that TikZ creates by default (similar to \jobname-mpgraph*, only serving a different purpose) and is only needed when a document is compiled on computer without tikz installed. (Low priority request.) Mojca

error: You can't use `\vadjust' in internal vertical mode
by Sanjoy Mahajan 12 Jun '09

12 Jun '09

I've been running across the following error once a week or so: [MP to PDF] (./fig.320) floatblocks : 16 placed !

I'm using context 2009.5.5 from the Debian unstable package. I tried running lumping.tex on the live context, but could not reproduce the problem. I think that is because the figure files are not included in the live run, and their absence changes the vertical spacing enough to hide the problem. I also tried downloading and running it through the latest minimals, but the minimals failed trying to load the palatino fonts, and I haven't yet figured out if that problem is with my setup or with the minimals. -Sanjoy `Until lions have their historians, tales of the hunt shall always glorify the hunters.' --African Proverb
