Mplib problem of latest beta on luatex 0.40

Mplib problem of latest beta on luatex 0.40

[Wei-Wei Guo]

Dear developers,

Here is the example and warnings.

Example:

     \startuseMPgraphic{mpos:par:columnset:textuline}
       \iftracepositions show_multi_pars \else draw_multi_pars \fi ;
       path p ; p := boundingbox currentpicture ;
       currentpicture := currentpicture shifted (0,-0.3*StrutDepth) ;
       setbounds currentpicture to p ;
     \stopuseMPgraphic

     \definetextbackground
       [underline]
       [location=text,
        alternative=1,
        mp=mpos:par:columnset:textuline,
        background=,
        frame=off]

     \starttext

     \underline{blurblur}

     \stoptext

The compiled result has no underline and ConTeXt complains during compilation:

     mplib           : making 'metafun.mp' into 
'/var/cache/texmf/luatex-cache/context/b51cb04348b3b14d1dfc7333fc9b63f2/formats/cont-en-metafun.mem'
     mplib           : problems with 'metafun.mp' from 
'/var/cache/texmf/luatex-cache/context/b51cb04348b3b14d1dfc7333fc9b63f2/formats/cont-en-metafun.mem'



Best wishes,
Wei-Wei

It works fine here with the latest beta and luatex 0.40. You may try
to delete luatex-cache and regenerate it.

It solves the problem, thanks.

I find another problem with the example in my previous email. I changed the
example a little bit.

Example:

     \startuseMPgraphic{mpos:par:columnset:textuline}
       \iftracepositions show_multi_pars \else draw_multi_pars \fi ;
       path p ; p := boundingbox currentpicture ;
       currentpicture := currentpicture shifted (0,0.3*StrutDepth) ;
       setbounds currentpicture to p ;
     \stopuseMPgraphic

     \definetextbackground
       [underline]
       [location=text,
        alternative=1,
        mp=mpos:par:columnset:textuline,
        background=,
        frame=off]

     \starttext

     \underline{blurblur}

     \underline{blurblur}

     \underline{blurblur}

     \underline{blurblur}

     \stoptext

The vertical positions of underlines are not stable. See the attached PDF file.


Best wishes,
