problem with TikZ & ConTeXt MKIV
by Mojca Miklavec 22 Jul '09

22 Jul '09

With 2009.07.20 09:35 MKIV & latest TikZ I get (among many other errors that follow) ! Undefined control sequence. \pgfutil@addpdfresource@colorspaces ...olorspaces {#1} l.396 ...rspaces{ /pgfprgb [/Pattern /DeviceRGB] } ? I don't know if that's a problem with TikZ or ConTeXt (no time to debug now, but maybe I can try to prepare some minimal example that fails; later). ConTeXt MKII works fine on the same document.

messy PDF (mkiv)
by Peter Rolf 21 Jul '09

21 Jul '09

Hi, while debugging I found some minor problems in the produced PDF code. There is a bug in one of the /Catalog entries (/PageLayout /auto). The other problems are more of cosmetic nature (only one harmless bug). The PDF for the attached example - contains 4 totally empty and *unreferenced* dictionaries (obj 5-8) (only cosmetic) - obj 11 is questionable (but I can't read the PS function code, so maybe it makes sense somehow) (only cosmetic) - obj 20 (/JavaScript) is referring to an empty /Names dictionary; should only be added if there is JS in the document And that's all for the moment (more to come with other example) :) Best wishes, Peter This is LuaTeX, Version beta-0.42.0-2009071821 MTXrun | current version: 2009.07.20 19:44 \setupcolors[state=start] \setuppagenumber[state=stop] \pdfcompresslevel=0 \starttext \null \startMPcode fill fullcircle scaled 5cm withcolor red; \stopMPcode \stoptext

lpdf.dictionary
by Peter Rolf 21 Jul '09

21 Jul '09

Hi Hans, can you implement *ordered* output with 'lpdf.dictionary'? There are two reasons why I ask. - My md5 hashing mechanism depends on the order of the entries. I think its much easier to implement an ordered output than to create a hashing mechanism, that checks for equal content. I also doubt, that there is a faster alternative for this job than md5. - Also debugging is a pain with longer dictionaries (I have to use a check list). Best wishes, Peter

appendtoks / csname
by Wolfgang Schuster 20 Jul '09

20 Jul '09

Hi, I look for a convient way to use \appendtoks with a token list which is accessed with \csname ... \endcsname, e.g. \appendtoks <something> \to\csname <mytoks>\endcsname This works when I enclose the \csname/\endcsname pair in braces \appendtoks <something> \to{\csname <mytoks>\endcsname} but this did not look very pleasant to my eyes. I thought something similar to \addvalue would be nice \addtoks{<mytoks>}{<something>} Wolfgang

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
