``a language where the programs are works of modern art''.
Piet is really esoteric, because the program is a picture.
In this stack oriented language the color areas represent numbers and changes in the color decide what to do - eg. push the number on the stack and the next color change may command: print it to the terminal.
npiet is an interpreter for piet programs and takes as input a portable pixmap (a ppm file) and since v0.3a png and gif files too - other formats may follow.
- latest complete source code of npiet, npietedit and
npiet-foogol (and manpages, examples and tests)
npiet-1.3f.tar.gz
[ Please have a look at the ChangeLog ].White Codel processing changed from npiet version 1.0 to 1.1 and now to v1.2 again hopefully with better tracing support. The backward compatibility parameter -v1 is gone, if you want an old version you may choose one of the old versions.
- the npiet C source: npiet-1.3f.c (v1.3f)
- the npiet manual-page: npiet(1)
- windows executable: npiet-1.3a-win32.zip (old version) (hopefully now statically linked and no other dll's necessary than the included cygwin1.dll)
Hint: If you get an error running npiet on your downloaded gif image about an unknown gif format -- just open it with gimp or another paint program and save it as ppm or png image -- and try again! Have fun!
npietedit is a editor to create small
piet programs. it's really helpful to get in touch with the piet
programming language.
- the Tcl/Tk source: npietedit-0.9d (v0.9d)
- the npietedit manual-page: npietedit(1)
npiet-foogol is a translator
from the foogol programming language to
the piet programming
language. It is far from complete, but as a start a Hello
World is correctly translated.
- the program itself (bison source): npiet-foogol-1.3.y (v1.3)
- the npiet-foogol manual-page: npiet-foogol(1)
- tbd: documentation...
And don't miss the picture gallery - where the
Art-Of-Programming needs a color printer ;-)

This program prints Hi
