by Peter Münster 05 Jan '13

Hi, Does the value 65436 have a special meaning, or is it a type? -*- mode: grep; default-directory: "/opt/context/tex/texmf-context/tex/context/base/" -*- Grep started at Thu Jan 3 23:59:25 grep -nH -e 65436 * font-age.lua:3268: ["wakatakanahalfwidth"]=65436, m-chart.lua:39: width = 100*65436, m-chart.lua:40: height = 50*65436, m-chart.lua:41: dx = 30*65436, m-chart.lua:42: dy = 30*65436, m-chart.lua:50: labeloffset = 5*65436, m-chart.lua:51: commentoffset = 5*65436, m-chart.lua:56: rulethickness = 65436, m-chart.lua:62: rulethickness = 65436, m-chart.lua:67: rulethickness = 65436, m-chart.lua:68: radius = 10*65436, m-steps.lua:20: dx = 10*65436, m-steps.lua:21: dy = 10*65436, m-steps.lua:25: offset = 2*65436, m-steps.lua:26: rulethickness = 65436, m-steps.lua:32: offset = 2*65436, m-steps.lua:33: distance = 4*65436, m-steps.lua:34: rulethickness = 65436, m-steps.lua:40: rulethickness = 65436, m-steps.lua:41: height = 30*65436, m-steps.lua:42: distance = 10*65436, m-steps.lua:43: offset = 5*65436, Grep finished (matches found) at Thu Jan 3 23:59:25 -- Peter

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

\startbuffer

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.

external pdf references
by Taco Hoekwater 11 Dec '12

11 Dec '12

Hi Hans, You know we at Docwolves do lots of stuff with \externalfigure[extern.pdf][interaction=yes] right? That sometimes produces errors. Some of those are hard to send back to you because the PDFs tend to be confidential, but there are two cases where valid but unexpected external references wreak havoc that are easy to explain and report: The first is: mailto:"someone(a)gmail.com" (with embedded " symbols). Resulting in ) expected near 'someone' error from lua, and it required us to patch context like so: \def\doifreferencefoundelse#1#2#3% {\ctxcommand {doifelsereference("\referenceprefix ",[[#1]], % "#1" \luaconditional \highlighthyperlinks , \luaconditional \gotonewwindow )} {\expandtexincurrentreference #2}{#3}} The second was a variation of: C:\TEMP\FILE.PDF (I forgot the real example). This of course results in Undefined control sequence: \\TEMP from luatex, and it required an extra line in link_uri in lpdf-epa.lua: local function link_uri(x,y,w,h,document,annotation) local url = annotation.A.URI url = string.gsub(url,"\\","/") -- TH Don't want backslashes here if url then add_link(x,y,w,h,format("url(%s)",url),"url") end end For the other bugs (which are ones where I often doubt whether the external pdf was even correct in the first place) I am attaching my versions of lpdf-epa.lua and lpdf-epd.lua for you to compare with your version. Unfortunately, we are using "2012.06.20 20:43", so that may be too old to help much. But you can grep for TH in the source and perhaps get some inspiration ;) Best wishes, Taco

The following simple code (an acute accent from TG Pagella): path p; p:=(302,643)..controls (302,662) and (288,677) ..(271,677)..controls (256,677) and (238,666) ..(216,644)..controls (216,644) and (78,506) ..(78,506)..controls (78,506) and (118,506) ..(118,506)..controls (118,506) and (262,596) ..(262,596)..controls (295,617) and (302,625) ..cycle; show turningnumber p; end. produces a strange result with the new Metapost, namely, turningnumber=6: This is MetaPost, version 1.770 (kpathsea version 6.1.1dev) 10 DEC 2012 15:35 **zz.mp (plain.mp Preloading the plain mem file, version 0.63)) (./zz.mp >> 6 A previous version of Metapost, 1.503, produces the correct result: This is MetaPost, version 1.503 (kpathsea version 6.0.0) 10 DEC 2012 15:42 **zz.mp (mpost15.mp (c:\BOP-UTI/lib-mfmp/0mp/plain.mp Preloading the plain mem file, version 0.63)) (./zz.mp >> 1 ) Of course, Metafont produces also the correct result as expected: This is METAFONT, Version 2.718281 (Web2C 2010) (base=mf 2011.1.14) 10 DEC 2012 15:35 **zz.mp (zz.mp >> 1 ) Cheers -- Jacko -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bogus\l{}aw Jackowski: B_Jackowski(a)GUST.ORG.PL ---------------------------------------------------------------- Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
