Supelec is back
by Taco Hoekwater 18 May '09

18 May '09

Hi all, For those of you who have not noticed yet: the foundry.supelec.fr server is back online with new hardware and software, and is running better than ever. There is a small snag that some of you may have noticed already: you will have to delete your current checkouts of all subversion projects, because the machine now solely talks DAV (and besides that, the repository UUIDs have changed as well). If you have made local changes, put them aside first. The svn diff command should still work as local changes are indeed remembered locally. Once you have secured everything you want to save, move or delete the whole old checkout, and run this command to get a new checkout: svn checkout --username <yourname> http://foundry.supelec.fr/svn/<project> Replace <project> with the project(s) you are working on and fill in your system login for <yourname>, or use "anonymous" for a read-only checkout (just hit <enter> at the password prompt in that case). Best wishes, Taco

MetaPost 1.200 announcement
by Taco Hoekwater 11 May '09

11 May '09

The MetaPost team is happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.200 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/projects/metapost/ This release will also be available from CTAN soon, and it will be included in the next TeXLive. The source package should compile normally on all systems that are capable of compiling a modern web2c-based TeX distribution. The win32 binary is intended for texlive or a similar web2c-based installation, this executable will *not* work for miktex. Of course, we welcome any comments (either good or bad) that you may have. Simply replying to this message is fine, but see the bottom of the message for a more formal way to report bugs and feature requests. ---------------------------------------------------------------------- What is new in MetaPost version 1.200: ---------------------------------------------------------------------- New features: * It is now possible to get the actual path drawing routines from a font glyph. The syntax is : q := glyph 113 of "cmr10"; q := glyph "one.oldstyle" of "lmr10"; "glyph" is a primary binary operator (like "subpath") that accepts a string or number and a string, and the result is a picture. The second argument is a tfm name. This will be combined with a fontmap entry to find the font's PostScript source file. If the first argument is a string, then it should be a Charstring name in the postscript font source. If the first argument is an integer, it is an index into the encoding of the font, and the Charstring that is mapped to that index is taken (it follows that numeric values have to be integers between 0 and 255). The returned picture can be empty (if the tfm or the pfb or the encoding or the Charstring was not found), otherwise it consists of a list of 'fill' objects that use the the 'grey' color model. Counterclockwise paths receive the grey value matching 'white', clockwise paths 'black'. * MetaPost now supports string valued internal variables. Three of these are predefined ("jobname", "outputformat", "outputtemplate"), you can add more of them via "newinternal". newinternal string s; s := "hello"; The type of a new internal is either 'string' or 'numeric', and defaults to numeric (this is for backward compatibility with older versions of MetaPost). String internals are initialized to the empty string, numeric internals are initialized to zero. * MetaPost now has a second backend that generates Scalable Vector Graphics output. This new backend was requested by Dave Crossland, who also provided the funding to make it possible. Dave, thank you again! The default value of "outputformat" is "eps"; when you assign "svg" you will get SVG output. If you use text labels with SVG, you will probably also want to set prologues:=3; With this setting, MetaPost will convert the font into curves (of course you also need a correct font map line, just as for PostScript output). With any other value of "prologues" you will simply get the SVG default text font in a system-dependant encoding. This is unlikely to be what you want! A simple example: outputformat := "svg"; outputtemplate := "%j-%c.svg"; beginfig(1); fill fullcircle scaled 100 withcolor .4red; endfig; end. In the lua bindings, there is the new figure method "svg()", that gives back the SVG output string. This is subtly different from the direct file output: the lua method does not prepend an XML declaration (this makes embedded use of the generated XML easier). * The new internal string variable "outputtemplate" replaces "filenametemplate". The big difference is that "outputtemplate" is a true 'internal', so that you need a proper assignment. On the positive side, this means that you can use its current value with e.g. show and message. * "outputtemplate" has a new type of replacement: internal variable names. Instead of the short "%j.%c", you could write: outputtemplate := "%{jobname}.%{charcode}" ; this type of replacement works for all internal variables, including those defined via "newinternal". * There are two new numeric internals: "hour" and "minute". (these are a consequence of the outputtemplate change) * The primitive "jobname" is now a string internal instead of a special case. This implies you can assign to "jobname", but such an assignment will only affect the picture output. The job name for the purposes of log and mem file names is fixed permanently at startup time and cannot be altered. * "mpost" can now pretend to be dvitomp. Either copy the executable to the name "dvitomp", or pass the switch --dvitomp on the command line. * The command line option --halt-on-error has been reinstated. * There is a new -s<internal>=<value> command line switch that can be used to setup run time values. Such assignment will be executed after initialization is complete (i.e. after mem file loading) but before any other code is executed. This works for all internal variables, including one defined that may have been defined in the mem file via "newinternal". * "tracingstats:=1;" now prints the highest and total input levels. Bug fixes: * The turningnumber calculation had a rounding error in the internal arithmetic that could cause incorrect numbers to be calculated (typically resulting in a 'turning numbers do not match' error). * The parsing of command line arguments with options was broken. * Reading of files with 8-bit names has been fixed. * A patch by Melissa O'Neill fixes inclusion of some special Type1 formats. * There was a bug where, when "prologues:=3;", the lists of the DocumentResources/DocumentSuppliedResources could appear in the eps output partially uncommented. * Troff labels were completely broken in all MPlib-based versions. Other changes: * Many, many improvements to the manual and the tutorial. Sorry Stephan, I don't know enough to list them all! * The old executable build system has been replaced by the new build system from the TeXLive 2009 repository. * The MetaPost (and mplib) source code is now released under LGPL instead of GPL, and uses a derivative of PyAvl instead of GNU libavl. * The web2c 'mktexfmt' feature is enabled for the program "mpost" once again. ---------------------------------------------------------------------- Legal notice / license / bug reports ---------------------------------------------------------------------- MetaPost is a system for producing graphics developed by John Hobby at AT&T, based on Donald Knuth's Metafont.

recent failure in mp graphics or clipping
by Mojca Miklavec 11 May '09

11 May '09

Hello Hans, I would need to create a minimal example, but I cannot do that before I get the module to work again (\savebuffer) and I need to finish the report first (before getting lost in bug reports instead of concentrating on content). When compiling one month old document with mkiv I stumble upon the following problem. I had to run mkii to generate external files first (via buffers) and then I tried to run mkiv and I get the following error report. If it rings any bell to you, feel free to fix it and I will gladly test it. (Which command exactly is undefined? \ifcsnameMPC can indeed only be found at a single place, most probably undefined indeed. I'm using clipping on PNG graphics if that helps.) Else I will come back to it once I'm finished with the report. (I'm still using mkii anyway, so there's no particular hurry.)

luatex beta 0.40.1
by Taco Hoekwater 08 May '09

08 May '09

Hi, I have just uploaded luatex 0.40.1 to the foundry server, and have committed the source code to texlive. What's new: * Vertical placement of root radicals and degrees is fixed. * The use of \pageleftoffset could deviate from \hoffset if \mag != 1000. * LuaTeX now issues a warning if \pagedir != \bodydir during shipout. * The previous crash in font.read_tfm() was still not quite correct. * The Web2C version is now also printed in the --version and --credits output. * There is a new MPlib 1.200 release candidate with a few minor fixes included. * The xpdf library is updated to patch level 3. * New imports to the build system, from texlive. In particular, there is now configure-level support for building with libpoppler and support for building under cygwin 1.7 is added. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.40.1 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

Hi, As Alan wrote, it seems there are continuous problems with both the minimals and the context mkiv distribution currently. Is there anything I myself can do to help out?

luatex beta 0.40.0
by Taco Hoekwater 27 Apr '09

27 Apr '09

Hi, I have just uploaded luatex 0.40.0 to the foundry server, and will commit the source code to texlive later today. What's new: * The embedded MPlib is updated to version 1.200. * Texlua would crash if run font.read_tfm() was used. * Luatex would crash on empty \patterns. * Lots of small C code cleanups. * \textdir inside a \hbox dir *** was wrong earlier. * 0.39.0 introduced a bug that would make luatex crash whenever font expansion was used. * Font tables returned by define_font can now have a key named 'cache' that controls the internal lua font table caching. * There is no longer a need for an explicit --progname if there is no input file given.

metapost 1.200-rc2 package tests wanted
by Taco Hoekwater 27 Apr '09

27 Apr '09

Hi all, I have just released a second candidate for metapost 1.200. New in this candidate is an altered syntax for string valued newinternals, as proposed by Stephan Hennig. Input should now look like this: newinternal string s;% new string internal with empty string value newinternal numeric num;% new numeric internal with zero value newinternal n;% for compatibility: same as 'newinternal numeric n;' Also, a buffer reallocation bug was found that could cause crashes. The packaged files are here: http://foundry.supelec.fr/frs/?group_id=13&release_id=336 Testing is more than welcome! Have fun, Taco

Norwegian in ConTeXt (a delayed answer)

It really doesn't hurt if we define two languages nb and nn (such as there are multiple languages for Czech/Slovak, Croatian/Bosnian/Serbian), and "remove" no, in the sense that no can be left as a synonym to nb only. Specifically: ------------- Hans F. Nordhaug: > I think "no" should be deprecated and giving a (useful) warning/error - > telling people to switch to "nb". ------------- Karl: To sum up, we need the following language codes: nb and nn. And we need the following mappings: bokmal --> nb bokmål --> nb (if possible) nynorsk --> nn norsk --> nb (with warning) norwegian --> nb (with warning) ------------- Mojca: You also need to ask Hans how to provide a "'no' is not allowed language switch" warning or error. What are you planning to do with the "norwegian" interface? Hans: why is "Norwegian" currently not listed in mult-sys.tex? Because only languages which need something different than "ec" need to be listed there or is there some other reason? Hans, you pointed out the chineese module ... but from what I can see there, one needs to include the module explicitely and ConTeXt users are pampered too much ;) (i.e. everything should happen automatically) - is there a way to say something like this? \startlanguage[nn] \setupitemize[stopper=] \definesymbol[1][\endash] \stoplanguage ------------- Karl/Mojca/Karl: >> leftquotation=\leftguillemot, >> rightquotation=\rightguillemot, > >Are the old values wrong or just an alternative? Well, there are no very strict rules in Norwegian; you *can* use every possible quotation mark. But the guillemots are certainly the preferred ones for (outer) quotations. ------------- Karl: My suggestion is \definesymbol[1][{\symbol[dash]}] \definesymbol[2][{\symbol[star]}] \definesymbol[3][{\symbol[circle]}] \definesymbol[4][{\symbol[bullet]}] \definesymbol[5][{\symbol[triangle]}] and leave levels 6+ at their defaults. Norwegian people, feel free to comment on this. :) ------------- Mojca: so it would really make sense to enable something like \startlanguagespecifics[nb] \setupitemize[stopper=] \definesymbol[1][{\symbol[dash]}] \definesymbol[2][{\symbol[star]}] \definesymbol[3][{\symbol[circle]}] \definesymbol[4][{\symbol[bullet]}] \definesymbol[5][{\symbol[triangle]}] \stoplanguagespecifics Perhaps that exists already, but I don't know how to do it. For Slovenian and Hungarian, the same "problem" exists. Now I use \def\placedotafter#1{#1.} \setuphead[section][numbercommand=\placedotafter] although it would be more clean if one could have something similar to \startlanguagespecifics[sl] \setupheads[stopper=.] \stoplanguagespecifics in default settings once that will be implemented. ------------- Karl: \setupheadtext [\s!nb] [\v!content=Innhold] \setupheadtext [\s!nn]

metapost 1.200-rc1 package tests wanted
by Taco Hoekwater 22 Apr '09

22 Apr '09

Hi all, I have just released a candidate package for metapost 1.200. The source code should be finished now, it will be imported in texlive in a minute. There are pending documentation changes but there is plenty of time before the texlive 2009 deadline for non- compiled source, so no rush there. I will not repeat the lengthy CHANGES entry here, you can read that in the file itself or under the notes link at supelec.fr: http://foundry.supelec.fr/frs/shownotes.php?release_id=335 The packaged files are here: http://foundry.supelec.fr/frs/?group_id=13&release_id=335 Testing is more than welcome! Have fun, Taco

luatex beta 0.39.0
by Taco Hoekwater 15 Apr '09

15 Apr '09

Hi, I have just uploaded luatex 0.39.0. This is the last beta before 0.40.0, and we consider it to be feature complete now. The difference between 0.39.0 and 0.40.0 will be nothing more than a newer version of MPlib, improvements to the manual, and (probably) a few bugfixes. What's new: * iniluatex will from now on start up with only the TeX82 primitives and \directlua, everything else has to be bootstrapped via tex.enableprimitives(). This change was planned for 0.40.0, but *now* is the time to test it. * A bugfix for \primitive in various expandable contexts, and \primitive now generates an error message when the argument is not actually a primitive's name. * There was a bug found in the math accent handling. * Large math operators are now treated like extensible characters in the sense that they can be composed of segments. * The extra assign- and restore tracing information from eTeX had a massive bug because of a dangling else in the pascal web. As a side-effect of fixing this bugs, all such potential errors in the pascal web have been fixed (for now). * The math parameters can now be set and queried from lua code via the new tex.setmath() and tex.getmath() functions. * Reflection in a \hbox was broken. * There was a leak of direction nodes in the paragraph builder. * The font backend now does a small peek to differentiate truetype and postscript style opentype fonts. This fixes the "Can't find CFF table" bug for otf's with truetype outlines. * Parameters and registers can now also be assinged to globally from lua (see the manual for details). * It is now possible to query the current math style while a formula is still being constructed by using the new read-only value \mathstyle. Associated is the new command \Ustack that is to be used as a prefix for {.. \over ..} and friends. See the manual for more information. * The embedded MPLib is brought up to date with the current metapost repository (version 1.110 and a few small patches). * Luatex can now handle two breakpoints inside a single ligature (like for the functional word of-f-ice). The solution is not perfect yet, but the chance of missed hyphenation points in actual documents should now be negligible. * Some speedups in the font loading code, and in the handling of pdf_literal nodes that are set from within Lua code. * Some source code and manual cleanup, as usual. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.39.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
