;;; Commentary:
|
||||
;; This file is now automatically loaded from ada-mode.el, and creates a submenu
|
||||
;; in Ada/ on the menu bar.
|
||||
|
||||
;;; 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 nondescript. 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 :-)
