6d528fc5 | 27 | ;; This file implements the code to create and edit customize buffers. |
c942535f | 28 | ;; |
d543e20b PA |
29 | ;; See `custom.el'. |
30 | ||

31 | ;; No commands should have names starting with `custom-' because |
32 | ;; that interferes with completion. Use `customize-' for commands | |
33 | ;; that the user will run with M-x, and `Custom-' for interactive commands. | |
34 | ||
9f5d3236 | 35 | ;; The identity of a customize option is represented by a Lisp symbol. |
62bf2fd1 | 36 | ;; The following values are associated with an option. |
9f5d3236 RS |
37 | |
38 | ;; 0. The current value. | |
39 | ||
40 | ;; This is the value of the option as seen by "the rest of Emacs". | |
41 | ||
42 | ;; Usually extracted by 'default-value', but can be extracted with | |
43 | ;; different means if the option symbol has the 'custom-get' | |
44 | ;; property. Similarly, set-default (or the 'custom-set' property) | |
45 | ;; can set it. | |
46 | ||
47 | ;; 1. The widget value. | |
48 | ||
62bf2fd1 | 49 | ;; This is the value shown in the widget in a customize buffer. |
9f5d3236 RS |
50 | |
51 | ;; 2. The customized value. | |
52 | ||
53 | ;; This is the last value given to the option through customize. | |
54 | ||
55 | ;; It is stored in the 'customized-value' property of the option, in a | |
62bf2fd1 | 56 | ;; cons-cell whose car evaluates to the customized value. |
9f5d3236 RS |
57 | |
58 | ;; 3. The saved value. | |
59 | ||
60 | ;; This is last value saved from customize. | |
61 | ||
62 | ;; It is stored in the 'saved-value' property of the option, in a | |
62bf2fd1 | 63 | ;; cons-cell whose car evaluates to the saved value. |
9f5d3236 RS |
64 | |
65 | ;; 4. The standard value. | |
66 | ||
67 | ;; This is the value given in the 'defcustom' declaration. | |
68 | ||
69 | ;; It is stored in the 'standard-value' property of the option, in a | |
62bf2fd1 | 70 | ;; cons-cell whose car evaluates to the standard value. |
9f5d3236 RS |
71 | |
72 | ;; 5. The "think" value. | |
62bf2fd1 LT |
73 | |
74 | ;; This is what customize thinks the current value should be. | |
75 | ||
76 | ;; This is the customized value, if any such value exists, otherwise | |
9f5d3236 | 77 | ;; the saved value, if that exists, and as a last resort the standard |
62bf2fd1 | 78 | ;; value. |
9f5d3236 RS |
79 | |
80 | ;; The reason for storing values unevaluated: This is so you can have | |
81 | ;; values that depend on the environment. For example, you can have a | |
62bf2fd1 | 82 | ;; variable that has one value when Emacs is running under a window |
9f5d3236 | 83 | ;; system, and another value on a tty. Since the evaluation is only done |
62bf2fd1 | 84 | ;; when the variable is first initialized, this is only relevant for the |
9f5d3236 RS |
85 | ;; saved (and standard) values, but affect others values for |
86 | ;; compatibility. | |
87 | ||
88 | ;; You can see (and modify and save) this unevaluated value by selecting | |
70482877 | 89 | ;; "Show Saved Lisp Expression" from the Lisp interface. This will |
9f5d3236 RS |
90 | ;; give you the unevaluated saved value, if any, otherwise the |
91 | ;; unevaluated standard value. | |
92 | ||
93 | ;; The possible states for a customize widget are: | |
94 | ||
95 | ;; 0. unknown | |
96 | ||
97 | ;; The state has not been determined yet. | |
98 | ||
99 | ;; 1. modified | |
100 | ||
101 | ;; The widget value is different from the current value. | |
102 | ||
103 | ;; 2. changed | |
62bf2fd1 LT |
104 | |
105 | ;; The current value is different from the "think" value. | |
9f5d3236 RS |
106 | |
107 | ;; 3. set | |
108 | ||
109 | ;; The "think" value is the customized value. | |
110 | ||
111 | ;; 4. saved | |
112 | ||
113 | ;; The "think" value is the saved value. | |
114 | ||
115 | ;; 5. standard | |
116 | ||
117 | ;; The "think" value is the standard value. | |
118 | ||
119 | ;; 6. rogue | |
120 | ||
62bf2fd1 | 121 | ;; There is no standard value. This means that the variable was |
f63d5a0e LT |
122 | ;; not defined with defcustom, nor handled in cus-start.el. Most |
123 | ;; standard interactive Custom commands do not let you create a | |
124 | ;; Custom buffer containing such variables. However, such Custom | |
125 | ;; buffers can be created, for instance, by calling | |
126 | ;; `customize-apropos' with a prefix arg or by calling | |
f32a1cb5 | 127 | ;; `customize-option' non-interactively. |
9f5d3236 RS |
128 | |
129 | ;; 7. hidden | |
130 | ||
131 | ;; There is no widget value. | |
132 | ||
133 | ;; 8. mismatch | |
134 | ||
135 | ;; The widget value is not valid member of the :type specified for the | |
62bf2fd1 | 136 | ;; option. |

1198 | The value of PACKAGE needs to be unique and it needs to match the | |
1199 | PACKAGE value appearing in the :package-version keyword. Since | |

4377 | You can set this option through Custom, if you carefully read the |
4378 | last paragraph below. However, usually it is simpler to write | |
4379 | something like the following in your init file: | |
4380 | ||
4381 | \(setq custom-file \"~/.emacs-custom.el\") | |
4382 | \(load custom-file) | |
4383 | ||
4384 | Note that both lines are necessary: the first line tells Custom to | |
4385 | save all customizations in this file, but does not load it. | |
4386 | ||
4387 | When you change this variable outside Custom, look in the | |
4388 | previous custom file \(usually your init file) for the | |
4389 | forms `(custom-set-variables ...)' and `(custom-set-faces ...)', | |
4390 | and copy them (whichever ones you find) to the new custom file. | |
4391 | This will preserve your existing customizations. | |
4392 | ||
4393 | If you save this option using Custom, Custom will write all | |
4394 | currently saved customizations, including the new one for this | |
4395 | option itself, into the file you specify, overwriting any | |
4396 | `custom-set-variables' and `custom-set-faces' forms already | |
4397 | present in that file. It will not delete any customizations from | |
4398 | the old custom file. You should do that manually if that is what you | |
4399 | want. You also have to put something like `\(load \"CUSTOM-FILE\") | |
4400 | in your init file, where CUSTOM-FILE is the actual name of the | |
