It appears the difference between using "display" and using "print" is that "print" outputs enclosing double quotes plus trailing newline; "display" outputs the unadorned string and no trailing newline. > -- Stratadrake > strata_ran...@hotmail.com > -------- > Numbers may not lie, but neither do they tell the whole truth. > > > > Date: Mon, 17 Sep 2012 18:47:38 -0400 > > From: ke...@ve3syb.ca > > To: gimp-user-list@gnome.org > > Subject: Re: [Gimp-user] script-fu: illegal function? > > > > On 12-09-17 02:28 PM, Gary Aitken wrote: > > > ((define (find-dot txt txtLen offset) (print "foo")) (find-dot "abcd.ef" > 7 1)) > > > > First, you wrapped the whole thing in ( ).

Re: [Gimp-user] script-fu: illegal function?
That's right - parentheses are not "free" in Scheme scripting, every opening parenthesis must be immediately followed by a function call. When you just want parentheses to group a few statements together with, call the (begin ... ) function: (begin (function a) (function b) (etc ) ... ) -- Stratadrake strata_ran...@hotmail.com Numbers may not lie, but neither do they tell the whole truth. > Date: Mon, 17 Sep 2012 18:47:38 -0400 > From: ke...@ve3syb.ca > To: gimp-user-list@gnome.org > Subject: Re: [Gimp-user] script-fu: illegal function? > > On 12-09-17 02:28 PM, Gary Aitken wrote: > > ((define (find-dot txt txtLen offset) (print "foo")) (find-dot "abcd.ef" 7 > > 1)) > > First, you wrapped the whole thing in ( ).

Drop the leading and trailing parentheses. Second, that is a line of Scheme code and Scheme does not contain a "print" function. You probably meant to use "display". Also keep in mind that the "display" function only takes a string so you may first need to convert what you pass it to a string. -- Cheers!

[Gimp-user] script-fu: illegal function?
When I try the following in the script-fu console: ((define (find-dot txt txtLen offset) (print "foo")) (find-dot "abcd.ef" 7 1)) "foo" Error: illegal function The find-dot macro obviously exists and is being executed. So what is the illegal function it is complaining about? Thanks ___ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list
