mpost -8bit not working on MikTeX
by Mojca Miklavec 30 Mar '08

30 Mar '08

Hello Hans, in tex.rb you pass the option -8bit to mpost. That option is (apparently - I have not tested, but see the list at the bottom) not available on MikTeX 2.7. I have no idea when this switch is needed and if there is any replacement for it, but it would be nice to fix the script in one way or another. Apparently this mechanism is going to change really soon anyway :), but for MikTeX it means waiting for the next version, so it might make sense to fix that and upload the fixed version to CTAN. (As far as I know, MikTeX is the only and the most important "user" of ConTeXt from CTAN, and it makes sense to keep some compromise of recent vs. stable version there.) Thanks, Mojca Here's an email sent to the MikTeX mailing list: On Sat, Mar 29, 2008 at 11:57 AM, <olivier.billet(a)orange-ftgroup.com> wrote: > Dear all, > > We are using MiKTeX 2.7 and ConTeXt and we are experiencing a bug during > the interaction of ConTeXt and metapost.

My ConTeXting is never-ending fight with strange behaviour/version dependency/bugs. This fight is a adventurous pleasure on one hand but sometimes also time-consuming pain on the other one. I am feeling a bit paranoid of that to being view a bug even where there no one is. Please do not read this as a complain. ConTeXt is too complicated piece of software that is why it is understandable. Problem (?) is it is still rapidly developed. Before some stabilization might bring nearer another reorganization/development (e.g. MKIV) fires :) Perhaps c'est la vie. Best Vit P.S. Thanks also to Hans for his answer.

by Taco Hoekwater 21 Mar '08

21 Mar '08

Hi all, I have just uploaded the archives for luatex 0.25.1, just a small intermediate release because I won't be around next week. * Updated to MPlib 0.30 (that is now becoming usable) * The build requirement for a pre-installed ctangle is gone (thanks to Martin) 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

[Fwd: TUG and Google's Summer of Code 2008]
by Taco Hoekwater 20 Mar '08

20 Mar '08

-------- Original Message -------- Subject: TUG and Google's Summer of Code 2008 Date: Wed, 19 Mar 2008 15:37:05 -0700 (PDT) From: Karl Berry <karl(a)tug.org> Organization: http://groups.google.com Newsgroups: comp.text.tex TUG has been accepted as a mentoring organization for Google's Summer of Code 2008, so thanks to Google. http://google-opensource.blogspot.com/2008/03/meet-your-mentors.html provides some background and next steps. If you are a TeX developer and have an idea for your package or program that could be usefully implemented by a student working full-time over the summer, and are (hopefully) willing to mentor the project, please email summer-of-code(a)tug.org with the details. See http://tug.org/gsoc/ for the ideas we've posted so far. You can also offer to mentor a package without specific projects in mind -- many students submit ideas of their own. Again, just let us know. If you are a student or know a student who might like to participate, please consider submitting an idea from the list, or one of your own. Early applications inevitably get more attention than later ones, so the sooner the better. Anyone is welcome to subscribe or post to our organizational SoC mailing list: http://tug.org/mailman/listinfo/summer-of-code. Thanks, Karl

bug in texexec --mptex
by Taco Hoekwater 17 Mar '08

17 Mar '08

Hi Hans, There is a small bug in texexec --mptex: it deletes lines starting with a # character because it believes those are comments. Not true. Example: beginfig(1); numeric #; # = 10; % remove leading space to get error label(btex $x_1$ etex, (#,#)); endfig; end (I found this because it happens in the MP manual macros) Best wishes, Taco

New imposition styles

[Dev-luatex] Luatex beta 0.25.0 released
by Taco Hoekwater 11 Mar '08

11 Mar '08

Hi all, I have just uploaded the archives for luatex 0.25.0 New: * mplib library: This version features an embedded MP interpreter whose output can be directly accessed from lua code (mplib), without calls to an external "mpost" command. Of course it has bugs and limitations (makempx does not work, for example) but keep in mind that it is only an initial attempt. See the manual for more details. * img library: ** img.immediatewrite() is added ** images now accept a 'transform' key ** widths etc. can now be given as width="100mm" Fixed: * \parshape handling was completely broken since 0.20.0+ * when \pdfprotrudechars was in effect, an assertion failure could happen when embedded \hboxes in the paragraph appeared at the end of a line. * import of otf fonts with contextual lookups has been debugged, thanks to a patch by GW himself. * compiling with gcc 4.2.3 is now supported * if you want to build from source, you need a pre-installed ctangle. 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 _______________________________________________ dev-luatex mailing list dev-luatex(a)ntg.nl http://www.ntg.nl/mailman/listinfo/dev-luatex

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
