metapost: unable to make mpx file error
\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.

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) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
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}?
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. On 28.09.2010 23:53, Stefan Müller wrote:
