6d528fc5 | 29 | ;; This file implements the code to create and edit customize buffers. |
c942535f | 30 | ;; |

31 | ;; See `custom.el'. |

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. | |
36 | ||
9f5d3236 | 37 | ;; The identity of a customize option is represented by a Lisp symbol. |
62bf2fd1 | 38 | ;; The following values are associated with an option. |
9f5d3236 RS |
39 | |
40 | ;; 0. The current value. | |
41 | ||
42 | ;; This is the value of the option as seen by "the rest of Emacs". | |
43 | ||
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) | |
47 | ;; can set it. | |
48 | ||
49 | ;; 1. The widget value. | |
50 | ||
62bf2fd1 | 51 | ;; This is the value shown in the widget in a customize buffer. |
9f5d3236 RS |
52 | |
53 | ;; 2. The customized value. | |
54 | ||
55 | ;; This is the last value given to the option through customize. | |
56 | ||
57 | ;; It is stored in the 'customized-value' property of the option, in a | |
62bf2fd1 | 58 | ;; cons-cell whose car evaluates to the customized value. |
9f5d3236 RS |
59 | |
60 | ;; 3. The saved value. | |
61 | ||
62 | ;; This is last value saved from customize. | |
63 | ||
64 | ;; It is stored in the 'saved-value' property of the option, in a | |
62bf2fd1 | 65 | ;; cons-cell whose car evaluates to the saved value. |
9f5d3236 RS |
66 | |
67 | ;; 4. The standard value. | |
68 | ||
69 | ;; This is the value given in the 'defcustom' declaration. | |
70 | ||
71 | ;; It is stored in the 'standard-value' property of the option, in a | |
62bf2fd1 | 72 | ;; cons-cell whose car evaluates to the standard value. |
9f5d3236 RS |
73 | |
74 | ;; 5. The "think" value. | |
62bf2fd1 LT |
75 | |
76 | ;; This is what customize thinks the current value should be. | |
77 | ||
78 | ;; This is the customized value, if any such value exists, otherwise | |
9f5d3236 | 79 | ;; the saved value, if that exists, and as a last resort the standard |
62bf2fd1 | 80 | ;; value. |
9f5d3236 RS |
81 | |
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 | |
62bf2fd1 | 84 | ;; variable that has one value when Emacs is running under a window |
9f5d3236 | 85 | ;; system, and another value on a tty. Since the evaluation is only done |
62bf2fd1 | 86 | ;; when the variable is first initialized, this is only relevant for the |
9f5d3236 RS |
87 | ;; saved (and standard) values, but affect others values for |
88 | ;; compatibility. | |
89 | ||
90 | ;; You can see (and modify and save) this unevaluated value by selecting | |
91 | ;; "Show initial Lisp expression" from the Lisp interface. This will | |
92 | ;; give you the unevaluated saved value, if any, otherwise the | |
93 | ;; unevaluated standard value. | |
94 | ||
95 | ;; The possible states for a customize widget are: | |
96 | ||
97 | ;; 0. unknown | |
98 | ||
99 | ;; The state has not been determined yet. | |
100 | ||
101 | ;; 1. modified | |
102 | ||
103 | ;; The widget value is different from the current value. | |
104 | ||
105 | ;; 2. changed | |
62bf2fd1 LT |
106 | |
107 | ;; The current value is different from the "think" value. | |
9f5d3236 RS |
108 | |
109 | ;; 3. set | |
110 | ||
111 | ;; The "think" value is the customized value. | |
112 | ||
113 | ;; 4. saved | |
114 | ||
115 | ;; The "think" value is the saved value. | |
116 | ||
117 | ;; 5. standard | |
118 | ||
119 | ;; The "think" value is the standard value. | |
120 | ||
121 | ;; 6. rogue | |
122 | ||
62bf2fd1 | 123 | ;; There is no standard value. This means that the variable was |
f32a1cb5 LT |
124 | ;; not defined with defcustom, nor handled in cus-start.el. You |
125 | ;; can not create a Custom buffer for such variables using the | |
126 | ;; normal interactive Custom commands. However, such Custom | |
127 | ;; buffers can be created in other ways, for instance, by calling | |
128 | ;; `customize-option' non-interactively. | |
9f5d3236 RS |
129 | |
130 | ;; 7. hidden | |
131 | ||
132 | ;; There is no widget value. | |
133 | ||
134 | ;; 8. mismatch | |
135 | ||
136 | ;; The widget value is not valid member of the :type specified for the | |
62bf2fd1 | 137 | ;; option. |

09b73f49 RS |

3889 | it should be an absolute file name. | |
3890 | ||
5aa971e3 LT |
3891 | You can set this option through Custom, if you carefully read the |
3892 | last paragraph below. However, usually it is simpler to write | |
3893 | something like the following in your init file: | |
3894 | ||
3895 | \(setq custom-file \"~/.emacs-custom.el\") | |
3896 | \(load custom-file) | |
3897 | ||
3898 | Note that both lines are necessary: the first line tells Custom to | |
3899 | save all customizations in this file, but does not load it. | |
3900 | ||
3901 | When you change this variable outside Custom, look in the | |
3902 | previous custom file \(usually your init file) for the | |
3903 | forms `(custom-set-variables ...)' and `(custom-set-faces ...)', | |
3904 | and copy them (whichever ones you find) to the new custom file. | |
3905 | This will preserve your existing customizations. | |
3906 | ||
3907 | If you save this option using Custom, Custom will write all | |
3908 | currently saved customizations, including the new one for this | |
3909 | option itself, into the file you specify, overwriting any | |
3910 | `custom-set-variables' and `custom-set-faces' forms already | |
3911 | present in that file. It will not delete any customizations from | |
3912 | the old custom file. You should do that manually if that is what you | |
3913 | want. You also have to put something like `\(load \"CUSTOM-FILE\") | |
3914 | in your init file, where CUSTOM-FILE is the actual name of the | |
3915 | file. Otherwise, Emacs will not load the file when it starts up, | |
