Using comment-region in function

Using comment-region in function

[Berthold Höllmann]

Hello,

I'm trying to write a skeleton to insert some blurb into newly
generated source files. The text should be the same and inserted as
comment regardles the programming language. I need a hint to achiev
this.

Regards
Berthold

Use `comment-region'?

(comment-region 
 (point)
 (progn
   (insert "This is a comment")
   (point)))

This does not work for skeletons:

(define-skeleton blurb-head
  "aa"
  "test: "
  "test " str > n)

(define-skeleton head
  "Insert a standard header for C files"
  ""
  (comment-region 
   (point)
   blurb-head
   (point)))

M-x head 

gives

eval: Symbol's value as variable is void: blurb-head

Changing "head" to

(define-skeleton head
  "Insert a standard header for C files"
  ""
  (comment-region 
   (point)
   (blurb-head)
   (point)))

gives

eval: Wrong type argument: number-or-marker-p, nil

is obviously wrong.  You can't leave out the `progn' from my example.

Sorry,

(define-skeleton head
  "Insert a standard header for C files"
  ""
  (comment-region 
   (point)
   (progn
     (blurb-head)
   (point))))

does work for this simple example. Still fighting with elisp.

Thanks
Berthold

You need a quote around the call to comment, otherwise skeleton will try to
insert whatever value is returned by comment-region.
