28 ;; WARNING: This package is still under construction and not all of
|
|
|
29 ;; the features below are implemented.
|
|
|
30 ;;
|
|
|
31 ;; This package provides a framework for adding user friendly
|
|
|
32 ;; customization support to Emacs. Having to do customization by
|
|
|
33 ;; editing a text file in some arcane syntax is user hostile in the
|
|
|
34 ;; extreme, and to most users emacs lisp definitely count as arcane.
|
|
|
35 ;;
|
|
|
36 ;; The intent is that authors of emacs lisp packages declare the
|
|
|
37 ;; variables intended for user customization with `custom-declare'.
|
|
|
38 ;; Custom can then automatically generate a customization buffer with
|
|
|
39 ;; `custom-buffer-create' where the user can edit the package
|
|
|
40 ;; variables in a simple and intuitive way, as well as a menu with
|
|
|
41 ;; `custom-menu-create' where he can set the more commonly used
|
|
|
42 ;; variables interactively.
|
|
|
43 ;;
|
|
|
44 ;; It is also possible to use custom for modifying the properties of
|
|
|
45 ;; other objects than the package itself, by specifying extra optional
|
|
|
46 ;; arguments to `custom-buffer-create'.
|
|
|
47 ;;
|
|
|
48 ;; Custom is inspired by OPEN LOOK property windows.
|
|
|
49
|
|
|
50 ;;; Todo:
|
|
|
51 ;;
|
|
|
52 ;; - Toggle documentation in three states `none', `one-line', `full'.
|
|
|
53 ;; - Function to generate an XEmacs menu from a CUSTOM.
|
|
|
54 ;; - Write TeXinfo documentation.
|
|
|
55 ;; - Make it possible to hide sections by clicking at the level.
|
|
|
56 ;; - Declare AUC TeX variables.
|
|
|
57 ;; - Declare (ding) Gnus variables.
|
|
|
58 ;; - Declare Emacs variables.
|
|
|
59 ;; - Implement remaining types.
|
|
|
60 ;; - XEmacs port.
|
|
|
61 ;; - Allow `URL', `info', and internal hypertext buttons.
|
|
|
62 ;; - Support meta-variables and goal directed customization.
|
|
|
63 ;; - Make it easy to declare custom types independently.
|
|
|
64 ;; - Make it possible to declare default value and type for a single
|
|
|
65 ;; variable, storing the data in a symbol property.
|
|
|
66 ;; - Syntactic sugar for CUSTOM declarations.
|
|
|
67 ;; - Use W3 for variable documentation.
