|
||
|
||
;;; History:
|
||
|
||
;; Created May 1987.
|
||
;; Original version from V. Bowman as in ada.el of Emacs-18
|
||
;; (borrowed heavily from Mick Jordan's Modula-2 package for GNU,
|
||
;; as modified by Peter Robinson, Michael Schmidt, and Tom Perrine.)
|
||
;;
|
||
;; Sep 1993. Daniel Pfeiffer <pfeiffer@cict.fr> (DP)
|
||
;; Introduced statement.el for smaller code and user configurability.
|
||
;;
|
||
;; Nov 1993. Rolf Ebert <ebert@enpc.fr> (RE) Moved the
|
||
;; skeleton generation into this separate file. The code still is
|
||
;; essentially written by DP
|
||
;;
|
||
;; Adapted Jun 1994. Markus Heritsch
|
||
;; <Markus.Heritsch@studbox.uni-stuttgart.de> (MH)
|
||
;; added menu bar support for templates
|
||
;;
|
||
;; 1994/12/02 Christian Egli <cegli@hcsd.hac.com>
|
||
;; General cleanup and bug fixes.
|
||
;;
|
||
;; 1995/12/20 John Hutchison <hutchiso@epi.syr.ge.com>
|
||
;; made it work with skeleton.el from Emacs-19.30. Several
|
||
;; enhancements and bug fixes.
|
||
|
||
;; BUGS:
|
||
;;;> I have the following suggestions for the function template: 1) I
|
||
;;;> don't want it automatically assigning it a name for the return variable. I
|
||
;;;> never want it to be called "Result" because that is nondescriptive. If you
|
||
;;;> must define a variable, give me the ability to specify its name.
|
||
;;;>
|
||
;;;> 2) You do not provide a type for variable 'Result'. Its type is the same
|
||
;;;> as the function's return type, which the template knows, so why force me
|
||
;;;> to type it in?
|
||
;;;>
|
||
|
||
;;;It would be nice if one could configure such layout details separately
|
||
;;;without patching the LISP code. Maybe the metalanguage used in ada-stmt.el
|
||
;;;could be taken even further, providing the user with some nice syntax
|
||
;;;for describing layout. Then my own hacks would survive the next
|
||
;;;update of the package :-)
