I am using skeletong often. And I was of opinion it was made to create
M-x interactive functions as skeletons to quickly insert such snippets
or interactive templates:
(define-skeleton dear-friend
"Start a letter"
nil
"Dear " (setq name (skeleton-read "Name: ")) ",
Thank you for your feedback.
" _ "
Greetings,
Joe
")
This gives me M-x dear-friend
If there is region marked the _ will replace it with region. It is
very handy.
Tim, I suggest that you define skeleton that works by
`define-skeleton' and then try using it in a function. On the other
hand using skeletons in function somehow beats their purpose.
(let ((somevalues '(("a" . "123") ("b" . "456"))))
(skeleton-insert
'(nil (setq str (skeleton-read "Var: "))
(cdr (assoc str somevalues)) | str ?\n)))
Does that work?
I have no idea what | means here.
