[Gimp-developer] siod
hello; just thought that some folks might find this of use or interest -- SIOD packages, for versions up to 3.0 or so, in the CMU AI repository: http://www-2.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/scheme/impl/siod/ SIOD docs, too: http://www.cs.indiana.edu/scheme-repository/imp/siod.html -- sean ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

(Or, even > better, in 1.2.x?) I'd like to replace our scheme implementation with something more advanced. The main reason is that I hope to improve error reporting and thus script debugging. Guile comes to mind but I don't have any experience with Scheme engines and I would love to see someone else taking the job of fixing Script-Fu for 1.4.

Note quite as memory efficient, sure, but you can make a list as big as available memory.

[Gimp-developer] siod (Script-Fu) string-length limitations
I've been experimenting with building a L-systems script-fu, but have hit a seemingly insuperable obstacle. It seems that there's a built-in limitation in siod that prevents strings from exceeding somewhere between 4050 and 4094 bytes. Since L-systems are basically string-rewriting systems, with the strings getting longer at each rewrite, this arbitrarily low limit is a real PITA. Indeed, it's a show-stopper. Despite the known annoyances of trying to do string handling in any lisp-like language, I started out using the scheme script-fu instead of perl in hopes of making the resulting script usable on windoze machines as well as Linux boxes. But when I finally got things working, the interpreter just dies/hangs when the strings start getting too long. There are no error messages, no core dumps, no segfaults -- it just stops, silently. So my questions are: (1) Is the specific version of siod that the GIMP uses documented anywhere? (2) Is there a sensible workaround for the (apparently) limited string length? (3) Is there a way to extend the GIMP's version of siod's capabilities to allow strings of arbitrary (large, very large) length in 1.4? (Or, even better, in 1.2.x?) -- --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/home.html Photo galleries ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

Translating those kinds of messages (which are even hard to grok if in english) does not make sense at all.

At a guess, wta means "wrong type for argument" I agree the message is pretty useless: you need to know what it means before you can understand it :) Austin ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

I am not sure, what exactly "wta" stands for, but at a first glance I'd say, that you try to do something like (car 123324), but car is only possible on lists and cons. > ERROR: wta(1st) to quotient (errorobj 150) - Again, one of my args, and > another nonsensical sounding error message..

No, no - '(120 120 120) is perfectly OK for color arguments.

[Gimp-developer] SIOD error codes
Well, finally got Win32 Gimp to compile (thanks Tor!) and now i am screwing around trying to get some script-fu working in batch mode.. Currently I am playing with the SIOD console, and getting very strange error messages.. (Preparing scripts to be run from batch mode).. For instance: ERROR: wta to car (errorobj 123324) - Ok, the 123324 is one of my arguments, but is the error message supposed to be in English? And... ERROR: wta(1st) to quotient (errorobj 150) - Again, one of my args, and another nonsensical sounding error message.. I looked through the developers Script-Fu FAQ, and a lot of the script-fu links are dead.. And I see no good reference to returned errors anywhere - anyone have a URL? Also, someone mentioned this earlier - does Gimp's batch mode processor support color arguments like '(120 120 120)? Or do they need to be converted into longs?
