\autoinsertnextspace (spac-hor.mkiv)
by Wolfgang Schuster 17 Jan '13

Hi Hans, the \autoinsertnextspace command fails when it gets a \par token. \starttext \dontleavehmode\autoinsertnextspace\par \stoptext The error disappears when you pass the argument to lua as a long string: \def\spac_spaces_auto_insert_next - {\ctxcommand{autonextspace("\meaning\nexttoken")}} % todo, just consult nexttoken at the lua end + {\ctxcommand{autonextspace(\!!bs\meaning\nexttoken\!!es)}} % todo, just consult nexttoken at the lua end Wolfgang

Hi Hans, what’s your opinion to redefine the leaders command to take a optional name which loads a predefined setup? <code> % use \doifsymbolelse for the symbol key? \unprotect \installcorenamespace{leaders} \installcorenamespace{leadersalternative} \installdefinehandler \??leaders {leaders} \??leaders \installparameterhandler \??leaders {leaders} \installsetuphandler \??leaders {leaders} \def\leaders {\doifnextoptionalelse\leaders_indeed\normalleaders} \def\leaders_indeed[#1]% {\def\currentleaders{#1}% \expandcheckedcsname\??leadersalternative{\leadersparameter\c!alternative}\s!default} \setvalue{\??leadersalternative\s!default}% {\leadersparameter\c!left \normalleaders\hbox to \leadersparameter\c!width{\hss\leadersparameter\c!symbol\hss}\hfill \leadersparameter\c!right} \setvalue{\??leadersalternative\s!default}% {\leadersparameter\c!left \normalleaders\hbox to \leadersparameter\c!width{\hss\leadersparameter\c!symbol\hss}\hfill \leadersparameter\c!right} \setvalue{\??leadersalternative\v!global}% {\leadersparameter\c!left \normalgleaders\hbox to \leadersparameter\c!width{\hss\leadersparameter\c!symbol\hss}\hfill \leadersparameter\c!right} \setupleaders [\c!width=1em, \c!symbol=., \c!alternative=\s!default] \protect \defineleaders[test]%[symbol=x] \starttext text\leaders\hbox to 1em{\hss .\hss}\hfill text text\leaders[test]text \stoptext </code> This method would be cleaner for user defined list layouts where one want to change the filler between the text and the page number because a setup like this isn’t something for a normal user. <code source="strc-lst.mkvi"> \definelistalternative [c] [\c!distance=5em, \c!width=0pt, \c!stretch=10em, \c!filler=\hskip.5em\gleaders\hbox to .5em{\hss.\hss}\hfill\hskip.5em\relax, \c!renderingsetup=\??listrenderings:abc] </code> Wolfgang

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, 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
