29 ;; This file implements the code to create and edit customize buffers.
33 ;; No commands should have names starting with `custom-' because
34 ;; that interferes with completion. Use `customize-' for commands
35 ;; that the user will run with M-x, and `Custom-' for interactive commands.
37 ;; The identity of a customize option is represented by a Lisp symbol.
38 ;; The following values are associated with an option.
40 ;; 0. The current value.
42 ;; This is the value of the option as seen by "the rest of Emacs".
44 ;; Usually extracted by 'default-value', but can be extracted with
45 ;; different means if the option symbol has the 'custom-get'
46 ;; property. Similarly, set-default (or the 'custom-set' property)
49 ;; 1. The widget value.
51 ;; This is the value shown in the widget in a customize buffer.
53 ;; 2. The customized value.
55 ;; This is the last value given to the option through customize.
57 ;; It is stored in the 'customized-value' property of the option, in a
58 ;; cons-cell whose car evaluates to the customized value.
60 ;; 3. The saved value.
62 ;; This is last value saved from customize.
64 ;; It is stored in the 'saved-value' property of the option, in a
65 ;; cons-cell whose car evaluates to the saved value.
67 ;; 4. The standard value.
69 ;; This is the value given in the 'defcustom' declaration.
71 ;; It is stored in the 'standard-value' property of the option, in a
72 ;; cons-cell whose car evaluates to the standard value.
74 ;; 5. The "think" value.
76 ;; This is what customize thinks the current value should be.
78 ;; This is the customized value, if any such value exists, otherwise
79 ;; the saved value, if that exists, and as a last resort the standard
82 ;; The reason for storing values unevaluated: This is so you can have
83 ;; values that depend on the environment. For example, you can have a
84 ;; variable that has one value when Emacs is running under a window
85 ;; system, and another value on a tty. Since the evaluation is only done
86 ;; when the variable is first initialized, this is only relevant for the
87 ;; saved (and standard) values, but affect others values for
90 ;; You can see (and modify and save) this unevaluated value by selecting
91 ;; "Show Saved Lisp Expression" from the Lisp interface. This will
92 ;; give you the unevaluated saved value, if any, otherwise the
93 ;; unevaluated standard value.
95 ;; The possible states for a customize widget are:
99 ;; The state has not been determined yet.
103 ;; The widget value is different from the current value.
107 ;; The current value is different from the "think" value.
111 ;; The "think" value is the customized value.
115 ;; The "think" value is the saved value.
119 ;; The "think" value is the standard value.
123 ;; There is no standard value. This means that the variable was
124 ;; not defined with defcustom, nor handled in cus-start.el. Most
125 ;; standard interactive Custom commands do not let you create a
126 ;; Custom buffer containing such variables. However, such Custom
127 ;; buffers can be created, for instance, by calling
128 ;; `customize-apropos' with a prefix arg or by calling
129 ;; `customize-option' non-interactively.
133 ;; There is no widget value.
137 ;; The widget value is not valid member of the :type specified for the

4015 The default is nil, which means to use your init file
4016 as specified by `user-init-file'. If the value is not nil,
4017 it should be an absolute file name.
4019 You can set this option through Custom, if you carefully read the
4020 last paragraph below. However, usually it is simpler to write
4021 something like the following in your init file:
4023 \(setq custom-file \"~/.emacs-custom.el\")
4026 Note that both lines are necessary: the first line tells Custom to
4027 save all customizations in this file, but does not load it.
4029 When you change this variable outside Custom, look in the
4030 previous custom file \(usually your init file) for the
4031 forms `(custom-set-variables ...)' and `(custom-set-faces ...)',
4032 and copy them (whichever ones you find) to the new custom file.
4033 This will preserve your existing customizations.
4035 If you save this option using Custom, Custom will write all
4036 currently saved customizations, including the new one for this
4037 option itself, into the file you specify, overwriting any
4038 `custom-set-variables' and `custom-set-faces' forms already
4039 present in that file. It will not delete any customizations from
4040 the old custom file. You should do that manually if that is what you
4041 want. You also have to put something like `\(load \"CUSTOM-FILE\")
4042 in your init file, where CUSTOM-FILE is the actual name of the
4043 file. Otherwise, Emacs will not load the file when it starts up,
