[mp-implementors] MetaPost 1.790
by Taco Hoekwater 17 Feb '13

17 Feb '13

I am happy to announce a new test release of MetaPost: ---------------------------------------------------------------------- MetaPost 1.790 ---------------------------------------------------------------------- This is a third test release for the new functionality planned in MetaPost 1.800. Besides a few bug fixes, this version has lots of internal speed-ups so that its running times should now be comparable to the MetaPost 1.50x series. All the reported new bugs in 1.780 have been fixed, but I may have introduced new problems while adding the speed optimizations. Use with care, and *do* let me know if something is wrong! This version will not be uploaded to CTAN / TLcontrib yet. The plan is to wait another for a few weeks before releasing 1.800. That will then be an official end-user release. The win32 binary can be downloaded immediately from files section at https://foundry.supelec.fr/projects/metapost/ The new foundry software is still not quite up to speed, so there is no source tarball uploaded yet (it was too large for the web form). If you want to build this latest MetaPost either wait a few days while Fabrice fixes foundry, or do an anonymous subversion checkout yourself: $ svn checkout --username anonsvn https://foundry.supelec.fr/svn/metapost/tags/1.790 The password is anonsvn ---------------------------------------------------------------------- What is new in MetaPost version 1.790: ---------------------------------------------------------------------- * Lots of speed-ups. * Fixed bug in division expressions that started with a literal number. * A few problems with bad deallocations were solved. * A bug where after saving and redefinition of primitives, they later were restored to 'undefined' instead of to their primitive meaning. * The "double" literal number parser now only accepts scientific notation if the character following 'E' or 'e' is '+', '-', or a digit. ---------------------------------------------------------------------- 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.

Difference between LM and CM font size
by Aditya Mahajan 11 Feb '13

11 Feb '13

Hi, While checking my context article for tugboat, Karl Berry found that typewriter fonts were coming out a bit smaller than expected. The following test file shows this: \starttext {\font\myfont = cmtt9 \myfont externalfigure[logo.pdf][width=1cm]} {\font\myfont = ec-lmtt9 \myfont externalfigure[logo.pdf][width=1cm]} \stoptext With ConTeXt MkIV 2013.01.27 (and also with ConTeXt TL), I get the attached output. Notice that the first and second line are of different height. Both lines are of the same height and width with MkII and with plain TeX. Any ideas on what is happening here? And more specifically, how can I get a typing environment whose font size is the same as that of cmtt9. Using \setuptyping[bodyfont=9pt] switches to font size that is the same as ec-lmtt9 in the above example. Aditya

Error with mtx-tools
by Aditya Mahajan 24 Jan '13

24 Jan '13

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

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
