Hallo, the following compiles ok, but gives me an status 3=fatal error. Can someone please point me to the error? \startlua mp = mplib.new ( { hash_size = 100000, main_memory = 2000000, param_size = 100000, } ) if mp then res = mp:execute( "beginfig(1) draw (0,0) .. (1,1) .. (2,1); endfig; bye;" ) tex.print("[" .. tostring(res.status) .. "]") mp:finish() end \stoplua Wolfgang

new version luatex / mkiv
by Hans Hagen 12 Apr '08

12 Apr '08

Hi, There is a new version of luatex and mkiv. You need to update them together. The best place to get them is the contextgarden (which will probably have the new versions pretty soon). This release of is rather substantial: no longer is metaposts called, but mplib is used instead. This bring down metapost runtime and conversion to nearly zero. The user interface is the same, but the implementation is different. Tomorrow (or so) taco will make releasenotes.

new version
by Hans Hagen 11 Apr '08

11 Apr '08

Hi, concerning the mplibrary in mkiv ... - it does not use the metafun mem file; when formats are generated a special mem file is made and put alongside the context format - however, this only happens when a new version is found (is the case with a new zip), or when an error is encountered in the format (compatibility issue) - in case of doubt, or when you patch metafun, you can say ctxtool --touch texexec --make i will try to make this more robust in the future the new mkiv mp graphics implementations is prepared for mixed usage, i.e. we can use multiple metapost formats; i'm still not sure about the interface, for instance: \startuseMPgraphic{metafun:bla} ... \startuseMPgraphic{mpost:bla} ... or so, more news later Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

mpost updating
by Wolfgang Werners-Lucchini 10 Apr '08

10 Apr '08

Hallo, I have updated an older ConTeXt (ver: 2007.07.29 22:06 MKII) with a aktuell mpost. I have used 'http://minimals.contextgarden.net/current/bin/metapost/mswin/bin/' as source. The command 'texmfstart texexec --autopdf --make --all' produces no metapost formats at all. Calling 'mpost.exe' I get a messagebox with the error: 'procedure entry point "kpse_record_input" in DLL "kpathsea356.dll" not found' (my translation from german). What is wrong here? Wolfgang

MetaPost 1.003 announcement
by Taco Hoekwater 10 Apr '08

10 Apr '08

The MetaPost team is happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.003 ---------------------------------------------------------------------- The sources and a win32 package can be downloaded immediately from http://foundry.supelec.fr/projects/metapost/ The source package should compile normally on all systems that are capable of compiling a modern web2c-based TeX distribution. The win32 package is intended for texlive or a similar web2c-based installation, and has been tested only with TeXLive 2007. These executables will *not* work for miktex, sorry. 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 version 1.003: ---------------------------------------------------------------------- * Polygonal pens now work better (bug #3 and #7 at supelec.fr). * When asking for a color part in a picture object, the color models now have to match each other, otherwise an error will be reported and the return value will be set to a 'black' part. * The Makefile fragment (metapost.mk) now defines a separate mpost target for better integration in TeXLive. * There was a bug in the internal handling of withprescript and withpostscript, resulting in incorrect output when paths using such scripts were stored in picture variables. * A newline was missing from the PostScript output when the procset internal variable was set, so the first line of that accidentally became a PostScript comment. * Applicable changes from Knuth's updates for MetaFont 2.718281 are incorporated. * Mpto did not play nice with %&<format> verbatimtex lines, it now automatically tries to detect comment-lines. * Dvitomp 1.003 has higher limits for some internal constants like the number of allowed fonts in DVI files. * The manual is improved. ---------------------------------------------------------------------- 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. The MetaPost home page is http://tug.org/metapost. MetaPost and related programs are in the public domain. The MetaPost development project is currently hosted at Supelec, https://foundry.supelec.fr/projects/metapost; please report bugs and request enhancements through there if possible. Alternatively, you can reach us through the <metapost(a)tug.org> mailing list as well. Have fun! Taco Hoekwater, for the MetaPost team, April 10, 2008.

Mapping to SmallCaps for Latin Modern
by Wolfgang Schuster 09 Apr '08

09 Apr '08

Hi Hans, the mapping for the SmallCaps fonts from Latin Modern use the slanted version for upright and the upright version for slanted style. font-otf.tex: \definefontsynonym [LMRoman10-CapsRegular] [file:lmromancaps10-oblique] [features=default] % features=smallcaps? \definefontsynonym [LMRoman10-CapsOblique] [file:lmromancaps10-regular] [features=default] should be \definefontsynonym [LMRoman10-CapsRegular] [file:lmromancaps10-regular] [features=default] \definefontsynonym [LMRoman10-CapsOblique] [file:lmromancaps10-oblique] [features=default] The mapping for the Dunhill style seems to be wrong too. \definefontsynonym [LMRoman10-Dunhill] [file:lmromandunh10-oblique] [features=default] \definefontsynonym [LMRoman10-DunhillOblique] [file:lmromandunh10-regular] [features=default] Wolfgang
