MetaPost 1.750 (alpha version)
by Taco Hoekwater 27 Apr '11

27 Apr '11

Hi all, Finally, I can release the first attempt at getting to metapost 2.0. ---------------------------------------------------------------------- MetaPost 1.750 ---------------------------------------------------------------------- The standalone distribution package and a win32 binary can be downloaded immediately from the 'experimental' files section at http://foundry.supelec.fr/gf/project/metapost/ *** This is an pre-alpha release for testing / experimenting only! *** It is able to process the images from mpman.mp (the metapost manual) but that is about the extent of the testing done so far, so expect lots and lots of bugs!. 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 1.750: ---------------------------------------------------------------------- * The mpost executable now accepts --math=double as an argument. This switches the internal arithmetic functions from using a scaled 32-bit data type to 64-bit floating point. * With --math=double, the input scanner has been changed to allow a := 1.0E20 as input format for a (any) numerical value ---------------------------------------------------------------------- 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.

\newconditional and Lua
by Wolfgang Schuster 26 Apr '11

26 Apr '11

Hi Hans, is there a simple way to change the status from commands created with \newconditional id \newif from, e.g. in the following example it’s easy to pass the value of the conditional from TeX to Lua but not in the reverse way. \newconditional\test \starttext \settrue\test TeX: \ifconditional\test TRUE\else FALSE\fi Lua: \startluacode if \luaconditional\test then context("TRUE") else context("FALSE") end \stopluacode TeX: \ifconditional\test TRUE\else FALSE\fi \stoptext When i change \newconditional to \newcount it’s easy but not very elegant. \newcount\test \starttext \settrue\test TeX: \ifconditional\test TRUE\else FALSE\fi Lua: \startluacode if \luaconditional\test then context("TRUE") else context("FALSE") end tex.count['test'] = 1 ; \stopluacode TeX: \ifconditional\test TRUE\else FALSE\fi \stoptext Wolfgang

bash vs sh in installation script
by Mojca Miklavec 17 Apr '11

17 Apr '11

Hello, Alan wrote me about the following issue. I don't know anything about bash/sh issues (except that sh is indeed more likely to be present and that I had to change many occurencies of /bin/sh to /bin/bash on garden because /bin/sh was a symlink to dash which didn't work). Does anyone object the change from bash to sh?

DefaultFont

Hi Hans, can you change the defintion of DefaultFont because it doesn’t work when you apply font features to it: \starttext \definedfont[DefaultFont]DefaultFont % works %\definedfont[DefaultFont*default]DefaultFont % breaks \stoptext type-set.mkiv - \definefontsynonym [DefaultFont] [cmvtt10] + \definefontsynonym [DefaultFont] [\s!file:lmmonoprop10-regular] Wolfgang

Luatex 0.66.0 announcement
by Taco Hoekwater 12 Apr '11

12 Apr '11

Hi, I have just uploaded the archives for a new luatex release, 0.66.0. This release has ongoing work on the 'epdf' lua interface by Hartmut (and that interface now has documentation as well). Besides that, the release fixes a number of the bugs that have been reported over the past months (mostly the smaller/easier ones). Luatex 0.66.0 will be the last release in the 0.6X series. The next release will be luatex 0.70.0;that will be the version on texlive 2011. Expect no major differences there either, the tracker has just a few items remaining for 0.70.0. Over the last half year, I personally have been much too busy with MetaPost to do any real work on luatex, hence the somewhat disappointing amount of feature progress. I have uploaded the 0.66.0 base package to tlcontrib as well, but please give the builders a few days to create actual platform- specific binaries. News: * fixed: linebreak_filter doesn't do its default job when tex.linebreak is used * fixed: \escapechar ignored by \meaning * fixed: wrong px default * fixed: font kern attribute inheritance * fixed: "nop" unrecognized in virtual fonts * fixed: assertion failure in dviluatex when font ptmr8t used * fixed: tex.settoks for with strings with embedded zeroes * fixed: an indexing problem with nonexistent font glyphs * fixed: some crashes and other bugs on the 'subtype' and 'prev' fields (not all node types have those fields) * fixed: crash on token.csname_id ("") * fixed: initialize the statically allocated node's type ids * fixed: fencepost error in math parameter counting * fixed: math family numbers > 255 are allowed * fixed: compilation failure on Hurd * fixed: a small bug leading to displacements when reading the AccentTop table * fixed: \directlua followed by \pdfximage generates error if draft mode is active * fixed: a problem with \vadjust pre in alignments * fixed: a lua stack growing problem in the backend in 0.65.0, resulting in an inability to create more than a few thousand generated pages * fixed: inclusion of Scribus-generated pdfs * adapt: the default form margin is now zero (was 1bp before) * adapt: libpng 1.4.4, zzuplib 0.13.60, mplib 1.504 * adapt: small changes to the build system and new imports from the texlive repository * feature: new function node.currentattr() queries the current active attribute list * feature: Lua font loading; ignore unknown enumeration keys in MathConstants * feature: JPEG 2000 image support * feature: continuing work on the 'epdf' library * doc: the 'epdf' lua library is now documented * doc: various other manual corrections The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.66.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

MkVI: Delimited Arguments
by Wolfgang Schuster 07 Apr '11

Hi Hans, the following example fails with named parameters, is this a limitation of mkvi? % macros=mkvi \def\definefoo[#1]% {\setvalue{start#1}{\dostartfoo{#1}}} \def\dostartfoo#1% {\normalexpanded{\def\noexpand\next##1\expandafter\noexpand\csname stop#1\endcsname}{#1 : ##1}% \next} %\def\definefoo[#name]% % {\setvalue{start#name}{\dostartfoo{#name}}} % %\def\dostartfoo#name% % {\normalexpanded{\def\noexpand\next#content\expandafter\noexpand\csname stop#name\endcsname}{#name : #content}% % \next} \starttext \definefoo[foo] \startfoo bar\stopfoo \stoptext Wolfgang
