[Gimp-developer] Script-Fu
Hello, I am currently working on a script-fu to provide previews of the more popular plug-ins with varying parameters. The script takes a list of images (blur.png, iir.png, rle.png, despeckle.png etc.), applies the respective plug-in with varying parameters and writes blur1.png, blur2.png, ..., blur(n).png, iir1.png, iir2.png, ..., iir(m).png etc., along with a file that records which filter/parameters were used for which image, for example: blur1.png: filter Blur Percent 20 Count 5 blur2.png: filter Blur Percent 40 Count 10 ... iir1.png: filter Gaussian Blur (IIR) Radius 3 Horizontal 7 Vertical 5 ... edge.png: filter Edge Amount 2 Wrap Mode SMEAR Algorithm Differential The thing is: The print command ((print test) ) is not working for me in batch-mode (Gimp 2.0.2). It does what it should on the Script-FU console, but shows no output when used like gimp -c -i -d -b '(filter-previews)' '(gimp-quit 0)' A more simple case: When I create this file (testprint.scm) in ~/gimp-2.0/script/: (define (testprint) (print this is a test)) and invoke gimp -c -i -d -b '(testprint)' '(gimp-quit 0)' I get: batch command: executed successfully. (and nothing else) Is this a bug? Another question: Can I - in Gimp-scheme - define the C-equivalent to variables declared static (at global, not procedural, level), that is, variables that are global (i.e., visible in all procedures), but only in a particular file? If not, can I declare variables that are *global*? How? I need this for the mapping of filters --- respective input-files, for example, I could use this: file_for_blur: blur.png file_for_iir: iir.png I know that I can always use define, like (define (blur-file) (set! return blur.png)) but that would not (really?) allow constructs like: file_for_blur: blur.png file_for_blur: blur_changed_my_mind_use_this_instead_but_keep_other_too.png file_for_blur: use_yet_another.png that is, set the variable to a different value on the fly (without the need to comment out anything). Moreover, does there exist reference documentation for basic Gimp-Scheme things (tutorials aside), like string-append etc.? Some standard Lisp-functions don't seem to be implemented (nth for example) Should I add some? Which ones?

At the first meeting we discussed the website and who to contact about things conserning the site, I said that I was willing to give it all a try and try to bring things up again. Because of this proposal it would be good to hear what everyone else that did not attend at the meeting thinks about this. If no onehas objections against this, then I will try my best to get things going with the website. Sounds great to me. The GIMP web site needs some love and care from someone who is willing to spend to some quality time with it - and if I know you right, scizzo, you're that kind of person.

Re: [Gimp-developer] Script-Fu
(define blur-file blur.png) (define blur-file otherblur.png) Different versions of Scheme handle this differently. I do not know if this is proper Gimp-scheme (re-defining a defined variable), or if one would have to use set! for the second definition/assignment. Incidently, no script-fu seems to make use of global variables, only of local let* - environments. Perhaps (define ...) is equivalent to (set! ...) here? I don't know officially, but it seems that with any definition of define, you can define it first, and then set! it everywhere else. Even if your first define is (define blur-file '()) Jon ___ Gimp-developer mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-developer

Even if your first define is (define blur-file '()) Yes, and what's more, one can also use set! alone (without a preceding define). I do not know if this is common practice in Scheme implementations nor if this will change when switching to Guile.
