MetaPost 1.201 announcement
by Taco Hoekwater 27 May '09

27 May '09

The MetaPost team is happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.201 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/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 1.201: ---------------------------------------------------------------------- Bug fixes: * There was a bug where sometimes the outer contour of a glyph that was asked for via 'glyph X of' was missing from te output, depending on the path drawing order inside the Type1 font. * Handling of MPTEXPRE label prefix files was broken. * Font subsetting for 8-bit characters in Type1 fonts was broken. * The use of "%{outputtemplate}" inside "outputtemplate" now generates an error. * The first letter of the input file name was swallowed in the log file. * There is some rudimentary support for infinite recursion trapping now, to help prevent segfaults&crashes due to C call stack exhaustion. * An unlucky change in glibc made compilation fail on new GNU/Linux systems due to multiple incompatible definitions of 'getline()'. * There was a bug in the handling of quoted external commands for MPXCOMMAND | MPXMAINCMD | TEX. * The main input file's opening brace and filename were not shown in the log file output. * Non-colored picture objects (clipping and setbounds paths) are now ignored when the color part is asked from within "within", for backward compatibility reasons. * The trip and trap files are now part of the distribution and the mptrap files have been updated. * The standard web2c argv[0] mem file mimicri was broken: 1.200 was always looking for "mpost.mem" even when called under another name. * The manual pages for "mpost" and "dvitomp" have been updated, and the old "mp" manual page has been removed. * The first letter of any missing input file name was not shown in the terminal error message. * Output files are now once again written in the current directory even if an explicit source directory is given. This includes the creation of mpx files, but some trickery is used so that up-to-date existing mpx files from the source directory take precedence. ---------------------------------------------------------------------- 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.

Making a minimals update svn friendly
by Oliver Buerschaper 24 May '09

24 May '09

Hi folks, what I would like to do is updating a minimal context tree which is under svn version control ... the problem with the current setup is that mtxrun mtx-update.lua deletes all .svn subdirectories in the destination directories it touches for synchronization. This is bad because it completely spoils version control. However, by supplying the additional flag --filter="P .svn" to the rsync command one should be able to sync and still preserve .svn subdirectories. Hence I suggest the following patches to mtxrun mtx-update.lua in order to make the updating process svn friendly: diff bin/mtxrun bin.orig/mtxrun 9384c9384 < --~ ["flags"] = "-rpztlv --stats --filter='P .svn'", --- > --~ ["flags"] = "-rpztlv --stats", diff bin/mtx-update.lua bin.orig/mtx-update.lua 459c459 < states.set("rsync.flags.normal", environment.argument("flags"), "-rpztlv --stats --filter='P .svn'", true) -- ok --- > states.set("rsync.flags.normal", environment.argument("flags"), "-rpztlv --stats", true) -- ok This works on my machine (Mac OS X 10.5.7). I'm afraid I cannot test this on other platforms at the moment ... What do you guys think? Best, Oliver

piping to ConTeXt
by Mojca Miklavec 24 May '09

24 May '09

Hello Hans, Asymptote developers wonder if there's a way to pipe to ConTeXt. I didn't start inspecting anything as I suspect that it's quite possible that nobody has ever tried that so far. The trick that John Bowman decided to use was to "\input null" (an empty tex file "null.tex"), but I already had problems because I (forgot that I) didn't have that file. Mojca

Hello Hans, I have file a-1.0.png. Using \extrernalfigure[a-1.0] (in mkii) results in "a-1" not found. \extrernalfigure[a-1.0.png] works OK. Is that behaviour expected/on purpose/hard to fix properly? Thanks, Mojca

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

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 10 May '09

10 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?
