Concatenate string and variable in script-fu (TinyScheme)

Question

I am trying to write a simple script-fu function. I want it to take a filename as argument and load this file from a folder (whose path will be hardcoded).

Base code:

(define (myfunction inputfile)
    (let * ( (image (cat (file-png-load 1 inputfile inputfile)
                                          ^^^^^^^^^
...

Here is what I want to achieve in a ecmascript syntax:

"foldername/" + inputfile

I have looked on the Scheme doc, but I see no example of variable+string concatenation...

Thanks in advance and have a nice day.

Answer 1

Well it seems that it was simpler than I thought

(string-append "myfolder/" infile")
