metapost: unable to make mpx file error

metapost: unable to make mpx file error

[Alan BRASLAU]

\startOT
	Wow! "experimental metapost version two"
	(does this mean that we get to play with precision?)
\stopOT

\startQUESTION
	The following minimal example yields an error:

\starttext
\startMPcode
	input circle ;
\stopMPcode
\stoptext

	where circle.mp contains a btex...etex sequence: 

draw fullcircle scaled 1cm ;
label (btex 1 cm etex , (0,0)) ;


	The "input circle ;" will work if I comment-out or remove label ;
	The minimal example will work, of course, if the mp code is
	in my tex file.

	The error message is:


mplib           : loading 'metafun.mp' (experimental metapost version two)
! mp terminal: (circle.mp
>> circle.mp
>> circle.mpx
! Unable to make mpx file.
l.2 label (btex
                1 cm etex , (0,0));

hm, looks like I have to intercept the inputs in order to turn the btex 
... into textexts (which happens with the main file)

what I actually need for this is a reader hook (just like we have a 
finder hook); I could use the finder hook to make a temporary file, but 
I wonder if that makes sense so let's first check if we can get a reader 
hook

(remind me in a few weeks anyway and use textext instead of btex/etex 
for the moment)

Re: Custom lua script (updating and debugging)

[Stefan Müller]

Hi,

thanks for the fast reply Mojca! Unfortunately it is still not working. Here 
is what I did. I'm afraid it has possibly more to do with pretty printers in 
particular (than lua scripts in general), but actually I have no idea.

I took the file
  MyConTeXtDir/tex/texmf-context/tex/context/base/pret-lua.lua
and copied it to
  MyConTeXtDir/tex/texmf-local/tex/context/user/pret-pas.lua
Next I replaced every occurance of "lua" in this new file by "pas" (so this 
changed the name of one function and renamed the visualizer itself). Then I 
ran "context --generate".

My testfile is added below. The "end" is typeset as if pret-pas.lua wouldn't 
exist. If I change "option=PAS" to "option=LUA" it works as intended ("end" is 
green). What is going on here? Any help is appreciated.

\installprettytype[PAS][PAS]
\setupcolors[state=start]
\setuptyping[option=color]
\definetyping[PAS][option=PAS, escape=yes, tab=4, numbering=line]

\starttext \startPAS
end
\stopPAS \stoptext

Thanks in advance,
Stefan.

PS: Additional question: Is it possible to integrate "option=color" into the 
"\definetyping[PAS]"? option={PAS,color}?

Re: Custom lua script (updating and debugging)

[Stefan Müller]

Sorry for replying to the wrong thread...

I just wanted to say that it works now. I justed started again from 
scratch and did the same as below. No idea what caused the trouble.

Thanks again,
Stefan.
