String problem [Solved by perseverance]

I have a problem with this command (gimp-drawable-set-name bkg-layer name-string)

I would like to set the name-string = ("background" random_gradient, gradient-type)

random_gradient and gradient-type are strings. Wilbur has scoffed at all my attempts

According to the 2.8.2 PDB, that procedure has been been depreciated.

You could use this instead.

(gimp-item-set-name bkg-layer "This is a string")

With either procedure...

In my example, the string is a constant. How are assigning a string to the name-string variable? It appears you are trying to assign multiple strings to a variable that should be a single string. Are you attempting to concatenate those strings?

Gnu-Tux I'm using 2-6-12, Wilbur and I have come to an agreement with this :yes

Code: Select all

(set! random_gradient (list-ref (cadr (gimp-gradients-get-list "")) (round (random (car (gimp-gradients-get-list ""))))))
    (set! gradient-type (+ (random 2) 6))
   (gimp-context-set-gradient random_gradient)
   (gimp-edit-blend bkg-layer CUSTOM-MODE NORMAL-MODE gradient-type 100 0 REPEAT-NONE FALSE FALSE 3 0.2 TRUE (/ width 2) (/ height 2) width height)
      (set! gradient-type-name
         (cond 
            (( equal? gradient-type 6 ) "GRADIENT-SHAPEBURST-ANGULAR" )
            (( equal? gradient-type 7 ) "GRADIENT-SHAPEBURST-SPHERICAL" )
            (( equal? gradient-type 8 ) "GRADIENT-SHAPEBURST-DIMPLED"  )))
            
   (set! name-string (string-append (car (gimp-drawable-get-name bkg-layer)) "-" random_gradient "-" gradient-type-name))

And at last it worked :rofl

Yes, concatenation with string-append. :bigthup

(set! name-string (string-append (car (gimp-drawable-get-name bkg-layer)) "-" random_gradient "-" gradient-type-name))

The syntax can be a little tricky/picky. :hehe
