Hello, does gimp use guile or does it have it's own scheme implementation? For example (I use gimp v.1.2.1 and guild 1.3.4): 1. in guile: (map + '(1 2 3) '(10 20 30)) gives me (11 22 33) which is correct. in gimp script: the same call gives me (1 2 3), obviously ignoring last argument. 2. I can not call "list?" function from gimp script. So, besides functions from DB Browser... what scheme functions are available? best regards, Zoran Bosnjak
