Hi Hans, can you add braces around the argument for the list key otherwise \savebuffer[a,b,…][…] won’t work. buff-ini.mkiv: \def\buff_save[#1][#2]% {\begingroup \doifassignmentelse{#1} {\setupcurrentsavebuffer[#1]}% - {\setupcurrentsavebuffer[\c!list=#1,\c!file=#2]}% + {\setupcurrentsavebuffer[\c!list={#1},\c!file=#2]}% \ctxcommand{savebuffer("\directsavebufferparameter\c!list","\directsavebufferparameter\c!file","\directsavebufferparameter\c!prefix")}% \endgroup} Wolfgang

Hi Hans, do you plan to add the \getbufferparagraphs command to MkIV or is it marked obsolete? Wolfgang

\startbuffer

02 Jan '13

Hi Hans, can you add a second (dummy) argument to \startbuffer. \setuvalue{\e!start\v!buffer}% {\begingroup % (3) \obeylines - \dosingleempty\buff_start} + \dodoubleempty\buff_start} -\def\buff_start[#1]% +\def\buff_start[#1][#2]% {\buff_start_indeed{}{#1}{\e!start\v!buffer}{\e!stop\v!buffer}} In the following example the space after the right bracket in “\startbuffer[test]” results in a empty first line in the buffer content and with a optional second argument this wouldn’t happen. \starttext \def\starttest{\grabbufferdata[test][starttest][stoptest]} \startbuffer[test] Text in a normal buffer. \stopbuffer “\getbufferdata[test]\removeunwantedspaces” \starttest Text in a customized buffer. \stoptest “\getbufferdata[test]\removeunwantedspaces” \stoptext Wolfgang

Luatex 0.74.0 announcement
by Taco Hoekwater 02 Jan '13

02 Jan '13

Hi, I have just uploaded the archives for a new luatex release, 0.74.0. Most noticeable changes: * Lua 5.2 There are no patches to the core Lua files; a future version of luatex will switch to loading the regular lua 5.2 dynamic library instead of depending on a statically compiled one. NOTE: This change can break some of your lua files, as the language has changed a little between versions 5.1 and 5.2 * A bleeding-edge version of luasocket is included, as there is no 5.2-compatible official release yet. * A new lua extension is the two-argument version of string.dump from Luajit: string.dump(function f, [boolean strip]) * Included mpost 1.780 * The implied existence of the following Lua libraries is now deprecated: debug, unicode.*, luazip, lfs, lpeg, zlib, gzip, md5, socket.*, profiler, epdf, fontloader, mplib, and pdfscanner. Future versions of luatex will load these modules on demand from dynamic libraries. Please update your sources to include a 'require' line for each of the library modules mentioned. * Two new callbacks: find_cidmap_file and load_cidmap_file (used by the fontloader to discover .cidmaps) 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-0.74.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

MetaPost 1.780
by Taco Hoekwater 24 Dec '12

24 Dec '12

We are happy to announce a new test release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.780 ---------------------------------------------------------------------- This is a second test release for the new functionality planned in MetaPost 1.800. This version will not be uploaded to CTAN / TLcontrib yet. The plan is to wait for a few weeks before releasing 1.800. That will then be an official end-user release. Bugs in the current version are still likely, so use with care! The standalone distribution package and a win32 binary can be downloaded immediately from http://foundry.supelec.fr/gf/project/metapost/ ---------------------------------------------------------------------- What is new in MetaPost version 1.780: ---------------------------------------------------------------------- * The turningnumber calculation in 1.770 was bugged. * The picture export in 1.770 forgot to add trailing zeroes to the log and term output channel resulting in rubbish output. * The arguments of the PS "dtransform" operator have been fixed (was wrong since 1.750). * The warning limit in numbersystem=double mode is now exactly 2**52. * A bunch of obvious memory leaks fixed. Not all yet, but now the MPlib seems to be usable even with many graphics. ---------------------------------------------------------------------- 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.
