Dear Emacs maintainers,
I'm trying to setup a clean set of skeletons, but it turns up that I
can't call a skeleton from another. The method I tried raises the error
message:
"skeleton-internal-1: Variable binding depth exceeds max-specpdl-size"
I tried to write a basic test to demonstrate the problem.
Here it is (nested-skeletons.el) :
**********************************************************************
;; Each skeleton is followed by a sample output
(define-skeleton tst:plain
"No prompt skeleton."
nil
"; I'm static text inserted by skeleton tst:plain"
)
; I'm static text inserted by skeleton tst:plain
(define-skeleton tst:use-str
"Interactive skeleton."
"Message: "
"; I'm generated text (" str ") inserted by skeleton tst:use-str" \n
)
; I'm generated text (yes) inserted by skeleton tst:use-str
(define-skeleton tst:skeleton-caller
"Calls another skeleton"
nil
"; I'm lazy. I want to reuse some ready-made skeleton" \n
(tst:plain) \n
"; Happy to see you again." \n
)
; I'm lazy. I want to reuse some ready-made skeleton
; I'm static text inserted by skeleton tst:plain
;; The cursor stops just after "plain", and I get the error message:
;; "skeleton-internal-1: Variable binding depth exceeds
max-specpdl-size"
;; or "skeleton-internal-1: Lisp nesting exceeds `max-lisp-eval-depth'"
;; in some previous sessions
(define-skeleton tst:skeleton-caller2
"Calls another skeleton"
nil
"; I'm lazy. I want to reuse some ready-made skeleton" \n
(tst:use-str "toy") \n
"; Happy to see you again." \n
)
; I'm lazy. I want to reuse some ready-made skeleton
; I'm generated text (toy) inserted by skeleton tst:use-str
;; same result

Please tell me if
- I did something wrong
- you need more information
- nested skeletons are not supported
- you can't reproduce the problem
I'm working on Ubuntu with emacs-snapshot package, and I still have
emacs22.
Thanks a lot.

Dear Emacs maintainers,

;; So "(progn expr nil) and it works !
(define-skeleton tst:skeleton-caller

(progn (tst:plain) nil) \n
"; Happy to see you again." \n

Sorry for the fuss.
Thanks a lot.

I have never worked on the code for skeletons, so I can't help you.
But your message inspired me to wonder whether the file of skeletons
should by default or convention be named closet.el.
