debugging script-fu with list->string

I believe Script-fu supports list->string but I may be mistaken. I am unable to get it to work. E.g. (gimp-message (list->string '(0 0 0) )) returns Error: ( : 2) string-set!: argument 3 must be: character

Both string-append and number->string work OK.

Please can someone provide example syntax.

Thanks

list->string is defined in the script-fu.init file. It takes a list of characters and returns a newly allocated string from formed form the characters in the list.

This is in accordance with the R5RS document (see page 30).

Cheers!

debugging script-fu with list->string

That is what I thought. Clearly something is wrong, but I am unable to identify the error. How, do I pass in a list of characters? GIMP complains when I try to pass in a list object. I have tried everything, I can think of.

Thanks.

Oops... I meant to send this to the list.

You provided a list but it was a list of numbers, not characters. To create a list of characters you would use
(gimp-message (list->string '(#\H #\e #\l #\l #\o #\!)))

Characters are written as #\ followed by a the character you want, or by #\ and the name of a character (ie. space, or newline).

For some additional information you can look in the R5RS under section 6.3.4 on page 28.

There is a minor error in the printing of characters that I need to fix. It shows them as "#\x" instead of just "#\". I also just had a thought that this information should be put in to some document about Script-Fu basics.

Cheers!

Kevin.

debugging script-fu with list->string

Ah!

Screwed that completely, didn't I? I had (wrongly) thought that list-

string, would return any old data list values to the error console,

and more easily than how I am currently doing it. Fool that I am!

Thanks, again!
