CTAN update: luamplib - ctan-ann

2 May 2024


      Dohyun Kim submitted an update to the
luamplib
package.
Version:  2.29.0 2024-05-01
License:  gpl2
Summary description:  Use LuaTeX’s built-in MetaPost interpreter
Announcement text:
----------------------------------------------------------------------
* provide new TeX macros to reduce typing toil.
mpfig ... endmpfig is roughly the abbreviation of
       egin{mplibcode}[@mpfig]
       beginfig(0)
       token list declared by everymplib[@mpfig]
       ...
       token list declared by everyendmplib[@mpfig]
       endfig;
       end{mplibcode}
mpfig* ... endmpfig is roughly the abbreviation of
       egin{mplibcode}[@mpfig]
       ...
       end{mplibcode}
These macros are protected and unexpandable.
   In these macros mpliblegacybehavior{false} is forcibly declared.
   As both share the same instance name, MetaPost codes are inherited among them.
   The instance name (default: @mpfig) can be changed by redefining `mpfiginstancename'.
* instance names are allowed in plain TeX as well. The syntax is:
mplibcode[name] ... endmplibcode
       everymplib[name]{ ... }
       everyendmplib[name]{ ... }
These macros are now protected and unexpandable.
* provide new MetaPost operators `mplibtexcolor' and `mplibrgbtexcolor'
   which convert TeX color expressions to MetaPost color expressions.
   The latter one forces rgb model results (#112). For instance,
mplibtexcolor olive     % => (0, 0, 1, 0.5)
       mplibrgbtexcolor olive  % => (0.5, 0.5, 0)
As spot colors are always forced to cmyk or rgb model, it is not
   recommended to use these operators for them.
* write down MetaPost messages into the log file
