mkiv and metapost
by Aditya Mahajan 11 Mar '08

11 Mar '08

Hi, Something is broken in the interaction between metapost and mkiv. The minimal example here gives me an empty pdf. \starttext \startMPcode draw fullcircle scaled 1cm; \stopMPcode \stoptext The metapost figure is created, but for some reason not is not being included. Doing an explicit \externalgraphics[filename-mpgraph.1] gives mp-test-mpgraph.1 !luaTeX error: internal error: unknown image type ==> Fatal error occurred, no output PDF file produced! I am using luatex snapshot-0.23.0-2008031110 and ConTeXt 2008.03.04 Aditya

Assertion failure with latest luatex
by Aditya Mahajan 11 Mar '08

11 Mar '08

Hi, I am using LuaTeX, Version snapshot-0.23.0-2008030822 and context 2008.03.04. In a long article, I get an error: luatex: ../../../../src/texk/web2c/luatexdir/tex/linebreak.c:215: find_protchar_right: Assertion `varmem[(varmem[((r)+1)].hh.v.RH)].hh.v.RH==r' failed. Is this a known bug? If not, I can try to create a minimal example. Aditya

includeMPgraphic

Hi Hans, I had a problem to compile an old 'followtokens' code (MKII). It seems to me there is a bug in the current supp-mps.tex. Please, can you correct it? Instead of: \def\includeMPgraphic#1% {\executeifdefined{\@@MPG#1}} it works: \def\includeMPgraphic#1% {\executeifdefined{\@@MPG#1}\gobbleoneargument} Best wishes Vit

BachoTeX 2008 -- Call for Papers -- reminder
by Jerzy B. Ludwichowski 04 Mar '08

04 Mar '08

Dear friends, The BachoTeX 2008 Program Committee dares to remind you of the quickly upcoming deadline for submitting paper proposals for the BachoTeX 2008 conference. The Call for Papers and TeX Pearls can be found http://www.gust.org.pl/BachoTeX/2008/cfp1en. We trust that the main theme of the conference, ,,TeX contra TeX'' should be of a great interest to the community at large and the various developers in particular. You may have noted that the supplementing theme "Aesthetic aspects of typesetting" is also addressed to those who use other typesetting software. If you know people active in this area please talk them into presenting a paper. Your children or very young TeXies in your vicinity are invited to contribute in the yet another conference supplementing theme "What is TeX to me?" Based on suggestions and experiences from previous years, one day of the conference will be devoted solely to working meetings of the various informal interest groups (no presentations): - fonts, - TeX engines, - distributions, - supporting software, - typesetting software in general, - propagating TeX, - history of TeX -- you name it. Talk your common interest buddies into coming and/or propose a paper. Do not forget submitting your "TeX Pearls" aka "TeX beauties and oddities"! And, finally -- registration is open at http://www.gust.org.pl/BachoTeX/2008/registration-en. Please note that early registration ending March 31 allows for a significant saving in the conference fee. Come and celebrate the XVIth, or $10000_{2}$ or $100_{4}$ or $20_{8}$ or $10_{16}$ BachoTeX! Jerzy Ludwichowski Organizing Committee

cyrillic glyphs
by Mojca Miklavec 29 Feb '08

29 Feb '08

Hello Hans, According to AGLFN at http://partners.adobe.com/public/developer/en/opentype/aglfn13.txt consider for example the glyph 0420;afii10034;CYRILLIC CAPITAL LETTER ER in char-def.lua you have [0x0420]={ ["adobename"]="afii0x2732", ["category"]="lu", ["cjkwd"]="a", ["contextname"]="cyrillicR", ["description"]="CYRILLIC CAPITAL LETTER ER", ["lccode"]=0x0440, ["linebreak"]="al", ["unicodeslot"]=0x0420, -- Р }, So: ["adobename"]="afii0x2732", "instead of" afii10034. What do you suggest? I guess that adobename might need to have multiple entries anyway. Mojca

Luatex beta 0.22.1 released
by Taco Hoekwater 27 Feb '08

27 Feb '08

Hi all, I have just uploaded the archives for luatex 0.22.1, that is a bugfix release for 0.22.0 Fixes and changes: * The macnames.c source file for building ttf2afm is restored. * "make depend" in luatexdir now works again * luatex sometimes crashed because it attempted to expand an already expanded font * luatex aborted when --progname was given but no format name. It now sets the format name to the given progname in that case * sometimes paragraphs with near-empty lines could cause a crash * img.supportedtypes() had a bug causing it to crash * img.supportedtypes() has been renamed to img.types for consistency * img.boxes() added, returns strings representing bounding boxes * img.node() added, returns a whatsit node cf. \pdfrefximage * node.write() now accepts multiple arguments * the program_name_set switch was not set automatically from C, causing errors unless lua code called kpse.set_program_name() explicitly * kpse.set_program_name() can now be called more than once in a single run. * os.spawn{...} and os.exec{...} could cause crashes because of a memory allocation error The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

why my first idea of experimental minimals didn't work out :)
by Mojca Miklavec 02 Feb '08

02 Feb '08

Hello (this is for amusement only - an interesting experience), if anyone would like to know why the idea with experimental branch of minimals didn't work out in its current form (I wanted to have a full tree and a separated tree with fixes only, but it took files from current and experimental in an arbitrary order). This is an answer from the mailing list: ------ Duh. I realize now that it's perfectly reasonable for you to be able to reproduce the problem while I can't. Versions 2.6.9 and earlier of rsync sort the file-list using the C library's quicksort, an unstable sort, so the results in case of duplicate files are highly sensitive to both the C library implementation and the order of directory entries in the source (which in turn is sensitive to the filesystem implementation). You probably have both a different C library and a different filesystem than I do. In any case, since rsync 3.0.0pre1, the default file-list sorting algorithm is a mergesort, which is stable, so files from earlier source arguments take priority. If you upgrade to an rsync 3.0.0pre* version, your scenario should work consistently. If it doesn't, that's a bug we should try to fix.
