I try to make some script for gimp, using script-fu, scheme.
Naturally, as a beginner, there are lots of errors and misunderstandings.
Now I'm looking for a way to debug those scripts.
I found (gimp-message), but the result does not show up. I'm not aware if there is a possibility to print debug messages to anywhere I could check them.
Generating new images filled with text would probably work ;-) but looks a bit like an overkill.
What ways to debug a script in gimp are there?
The output of gimp-message goes to the "Error console" (if you have this dockable dialog setup), otherwise in a warning dialog.
If you are in Linux or OSX, you can also start Gimp from a terminal and use (print ...) calls, they will show in the terminal.
You can make your life easier and write your scripts in Python (easier to learn, and more powerful...). See here for the doc, here for some examples, and here for some debug tricks for Windows.
