Hi, Running mtxrun --script tools --dirtoxml gives an error. ...minimals/texmf-context/scripts/context/lua/mtx-tools.lua:127: attempt to call global 'extname' (a nil value) Adding local extname = file.extname fixed this issue. Aditya

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

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

Leaders
by Wolfgang Schuster 13 Jan '13

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
