Dohyun Kim submitted an update to the
luamplib
package.
Version: 2.29.0 2024-05-01

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
\begin{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
\begin{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
