[Gimp-developer] script-fu-scheme: Full implementation of Scheme?
Hello, the tutorials I found cover a small portion of the Scheme language. Often there's not even a conditional call (if) or loop like (while) explained (but they are nice introductions!). At http://www.swiss.ai.mit.edu/projects/scheme/documentation/scheme.html there's a reference manual, but I didn't manage to get some functions... to work. How about e.g. the (do) statement or (floor -4.3) (round -4.3)at scheme_5.html#SEC56 ..? It didn't work at the GIMP 1.2.3 script-fu console Is there a reference manual of the script-fu implemented Scheme?

Gimp currently uses SIOD, which is a nonstandard implementation of Scheme with some of the standard Scheme functions, some functions imported from C, and some just plain strange stuff (what is the MD5 calculator doing in a lightweight scheme implementation?). A hodgepodge of stuff, really. Then, of course, there is the gimp extensions to it, which are rather strange in of themselves... Anyway, the definative reference for SIOD is now http://people.delphiforums.com/gjc/siod.html (it took some poking around to find that site -- most people refer to an older document at indiana.edu) Rockwalrus ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

However, not all of SIOD is implemented in the GIMP. Specifically, all of the stuff that requires a platform specific implementation is missing. These functions were marked with a U in the old Indiana doc. I don't know if that's true on the newer site referenced below. s/KAM - Original Message - From: Nathan Carl Summers [EMAIL PROTECTED] To: Martin Bernreuther [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Wednesday, October 30, 2002 4:32 PM Subject: Re: [Gimp-developer] script-fu-scheme: Full implementation of Scheme?

These functions were marked with a U in the old Indiana doc. I don't know if that's true on the newer site referenced below. The big U is in the new doc as well. It's not completely reliable, though -- a few of the big U's are in script-fu, and a few of the functions not marked with a U as missing as well. datlength and datref are the only ones I can remember that aren't marked with a U and aren't present. (Which is annoying, since datref can be useful for parasites.) Rockwalrus ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

I've posted the siod documentation that I use on my website at http://trefftzs.topcities.com/siod.html It also shows functions that are not available in the Gimp, but fewer than your source. I seem to remember that I had to roll my own floor, ceil, and round functions. Good luck. -- --Jeff Jeff Trefftzs [EMAIL PROTECTED] http://www.tcsn.net/trefftzsHome Page http://gug.sunsite.dk/gallery.php?artist=68 Gimp Gallery http://trefftzs.topcities.com/ Photo Gallery ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer
