[NTG-context] Mplib problem of latest beta on luatex 0.40

2009-04-26 Thread 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,
Wei-Wei
