Hi,

I'm writing a script-fu GIMP plugin and I need to be able to write some decimal values to a file during the execution of the script. I've seen some people suggesting that use of fprintf, etc., but can't figure out how to get this to work. Can someone please provide some guidance?

Thanks! Dave

Hi,

fprintf() is a C function, and because it does I/O, it's unlikely to be exposed to Script-Fu. Script-Fu cannot, for instance, delete files, so I would expect it cannot directly create files either (only save images using gimp-file-save.). I recommend you look up a reference for the Script-Fu API. plug-ins/script-fu/tinyscheme/Manual.txt is the one you probably want. It looks like Script-fu actually does support I/O. (that file is in the SVN repository; it might also be in a distribution tarball (eg. gimp-2.3.19.tar.bz2)

If you are using GIMP 2.3.14 or later, the following code should demonstrate how to write to a file:

(define outport (open-output-file "samplefile.txt")) (display "Hello" outport)
(newline outport)
(display "World" outport)
(close-output-port outport)

If you are using a stable version (2.2.x) of the GIMP, then you will need to use SIOD's 'fopen', 'fwrite', and 'fclose' functions.

(define outfile (fopen "samplefile.txt" "w")) (fwrite "Hello" outfile)
(fwrite "\n" outfile)
(fwrite "World" outfile)
(fclose outfile)

Thanks!

When I try to write something in a file, I get a similar error. But soon I will have to write an important student paper, so I am looking for a reliable writing service. A friend of mine recommends this one - https://supremedissertations.com/ and says that he ordered student papers from them several times. I think this is a reasonable decision in this situation.
