How to view .mp output files from Functional MetaPost

Question

I am interested in using Functional MetaPost on Mac OS X:

http://cryp.to/funcmp/

I am looking for a tutorial, for example:

http://haskell.org/haskellwiki/Haskell_in_5_steps

but for a trivial FuncMP example, that is, using GHC, I can compile something simple, for example:

import FMP  
myPicture = text "blah"  
main = generate "foo" 1 myPicture  

but i can't figure out how to view this output foo.1.mp. (It gives a runtime error without finding "virmp", my MetaPost build is "mpost", I can’t figure out how to override this parameter or what my .FunMP file is or should do ...) I can run mpost, but the output (foo.1.1) is what, PostScript? EPS? How to use it? (I think I just need a simple LaTeX file with an EPS drawing in it, or something else ...)

Preferably, I would like to generate output (.ps or .pdf that I can view), so I actually get somewhere with Functional MetaPost, studying it, playing with it, without banging my head on the path and the binaries and shell of the command .

Answer 1

@ja: That's right (EPS should be mpost output), but there are a few problems here:

• ghostview uses X11 and is ugly (especially on a Mac) to such an extent that it is difficult to use.

• I need smooth, smooth graphics, in particular PDF, so I can import the graphics into Photoshop when I'm done --- the results on the screen matter!

• In the end, I'm not the only one having problems with the non-standard output of Metapost Functional Metapost .

• Metapost ( , 3D!), ( , Pythonic/Java-ish).

Answer 2

mpost - eps, ghostview...
