Nested \setupXXX commands
by Wolfgang Schuster 26 Mar '13

26 Mar '13

Hi Hans, there is a problem with the command handler and nested \setup… commands. In the following example the setting for the “two” environment are ignored. <example> \defineenumeration[one][text=One] \defineenumeration[two][text=Two] \setupenumeration[one,two][alternative=serried,color=red] \starttext \startone First enumeration. \stopone \starttwo Second enumeration. \stoptwo \stoptext </example> The reason for this behavior is the \setupcounter call in \everysetupenumeration. When you look at the internal code for \setupenumeration (mult-aux.mkiv) you see that the first element in \setupernumeration (i.e. “one”) is processed with \mult_interfaces_with_comma_list_element, at the end of this macro \everysetupenumeration. At this point \setupcounter is used which redefines \mult_interfaces_with_comma_list_element. This redefined version is used for the next element (i.e. “two”) in \setupenumeration and the values are no passed (“alternative” and “color”) to \setupcounter. \unexpanded\def\mult_interfaces_install_setup_handler#1#2#3#4#5#6#7#8% {\ifx#3\relax\let#3\empty\fi \unexpanded\def#2{\dodoubleempty#4}% \unexpanded\def#6{\mult_interfaces_get_parameters{#1#3:}}% no every ! don't change it \newtoks#5% \newtoks#8% \unexpanded\def#4[##1][##2]% maybe helper {\let#7#3% \ifsecondargument \def\mult_interfaces_with_comma_list_element####1% we will have a simple one as well {\edef#3{####1}% \mult_interfaces_get_parameters{#1#3:}[##2]% \the#5}% \processcommalist[##1]\mult_interfaces_with_comma_list_element \else \let#3\empty \mult_interfaces_get_parameters{#1:}[##1]% \the#5% \fi \let#3#7% \the#8}} Wolfgang

MetaPost 1.800 announcement
by Taco Hoekwater 19 Mar '13

19 Mar '13

I am happy to announce a new release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.800 ---------------------------------------------------------------------- This version will be the one included in TeXLive 2013. The major changes compared to MetaPost 1.504 that was in TeXLive 2012 are: * Support for IEEE double (64 bit) internal calculations as well as traditional 32-bit scaled arithmetic, by means of a command-line switch (--numbersystem=double). * Bitmap (png) output support. * The C and lua APIs have been extended to allow path control point resolution without going through the Metapost input language. * The code for picture shipout now uses "double" for all floating point values. This can give small differences in the actual output files in traditional mode due to the required scaled -> double conversion, but it was necessary to support the new numerical backend code. The win32 binary as well as a source archive can be downloaded immediately from the files section at https://foundry.supelec.fr/projects/metapost/ If you want to build MetaPost yourself, you can also do an anonymous subversion checkout: $ svn checkout --username anonsvn https://foundry.supelec.fr/svn/metapost/tags/1.800 The password is anonsvn ---------------------------------------------------------------------- What is new in MetaPost version 1.800: ---------------------------------------------------------------------- * A new string valued internal "outputformatoptions" is used by 'png' output format to control the png file format. In the future, this internal may become used for options to the other output formats as well. The syntax for "outputformatoptions" is a space-separated list of settings. Individual settings are keyword+'='+value. The only currently allowed ones are: format=[rgba|rgb|graya|gray] antialias=[none|fast|good|best] No spaces are allowed on the left, nor on the right, of the equals sign inside a setting. The assignment that would match the compiled-in default setup is: outputformatoptions := "format=rgba antialias=fast"; however, "outputformatoptions" is initially the empty string. Some notes on the (new) PNG output formats: - The 'rgb' and 'gray' subformats have a white background. The 'rgba' and 'graya' subformats have a transparent background. - Bitdepth is always 8. - In all cases, the image is initially created in 8-bit RGB mode. For 'gray' and 'graya', the RGB colors are reduced just before the actual PNG file is written, using a standard rule: g = 0.2126*r + 0.7152*g + 0.0722*b - CMYK colors are always converted to RGB during generation of the output image using: r = 1 - (c+k>1 ? 1 : c+k); g = 1 - (m+k>1 ? 1 : m+k); b = 1 - (y+k>1 ? 1 : y+k); - If you care about color conversions, you should be doing a "within <pic>" loop inside "extra_endfig". The built-in conversions are more of a fallback. * A new string-valued internal "outputfilename", which is set by "shipout" to the value of the just created file name. Until the first shipout has occurred, it is the empty string. ---------------------------------------------------------------------- What is fixed in MetaPost version 1.800: ---------------------------------------------------------------------- * Fixed a number of bugs where Metapost loaded the default font map file multiple times, resulting in lots of "fontmap entry for `<fontname>' already exists, duplicates ignored" warnings. * The "glyph <> of <>" operation could crash on fonts with empty subpaths in the charstrings. * Fixed a bug in the postscript encoding reader that caused a buffer overflow (fatal error) for encoding files that do not end with a newline. * Sped up png creation a bit by using smarter libpng options. * In the 'double' numbersystem, lots of precision was lost due to a bad internal conversion of fractions to scaled values. This affected the "rotated by", "directiontime", "sind" and "cosd" primitives, as well as internal dependency calculations. * In the 'double' numbersystem, an internal rounding error caused "directiontime" to return bad results for requests near zero. * There was a big scaling miscalculation while outputting glyphs in SVG mode with "prologues:=3". The output labels were so big that they fell completely outside of the generated image. * A problem resulting in 'This can't happen (endinput)' caused by a missing "end" at the end of the run was fixed. ---------------------------------------------------------------------- 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.

new font trickery
by Hans Hagen 14 Mar '13

14 Mar '13

Hi, I implemented this: \setupbodyfont[pagella] \starttext \dorecurse{10}{ \dorecurse{20}{ \start What \recursedepth\recurselevel\space \feature{smallcaps} What \recursedepth\recurselevel\space \feature{oldstyle} What \recursedepth\recurselevel\space \stop } \par } \stoptext A reasonable fast cummulative feature switcher (so its different from addff cum suis). I'm not aure about the name yet. Also, such features have a semi-global nature in the sense that redefining 'oldstyle' has no effect, but that's sort of natural. Of course it's somewhat slower than defining a font with specific features enabled.

Luatex 0.75.0 announcement
by Taco Hoekwater 04 Mar '13

04 Mar '13

Hi, I have just uploaded the archives for a new luatex release, 0.75.0. Most noticeable changes: * New expandable primitive \Uchar. * Metapost 1.790. * New version of lnodelib.c with speedups by Hans and Luigi. Also added some extra sanity checks to the Lua node field setting functions. * Support 'umath' in tex.extraprimitives(), so that formats can make the \Umath* primitives unprefixed, now that they will be provided by XeTeX as well. * Removed a bunch of deprecated primitives * \AlephVersion, \Alephrevision, \Alephversion, \Alephminorversion * \OmegaVersion, \Omegarevision, \Omegaversion, \Omegaminorversion * \omathcode, \odelcode, \omathchardef, \omathchar, \omathaccent, \odelimiter, \oradical * \Umathbotaccent, \Umathaccents * Fix large file support. * Fix Lua's loadfile(). * Removed the cidmap callbacks again (let that be done by user lua code after the fact). * Removed the fatal error on fonts where num_glyphs is too high, as that problem is actually harmless. * Some compilation issues under Win32 and Solaris resolved. NOTE: You still need an 'installed' pkg-config while building luatex. Either install pkg-config for your platform, or make sure there is a binary linking to /bin/true while configuring. The requirement is for the executable 'pkg-config' itself, not for any particular package. * Allow math extender objects to be zero width. * The 'epdf' library has been extended to deal with finding and saving embedded files (catalog:numEmbeddedFiles() and catalog: embeddedFile, new EmbFile object). The archives can be downloaded from supelec as usual: https://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co --username anonsvn --password anonsvn \ https://foundry.supelec.fr/svn/luatex/tags/beta-0.75.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
