26 | ;; | |
27 | ;; This file defines some simple operations that can be used for | |
28 | ;; maintaining the `face-remapping-alist' in a cooperative way. This is | |
29 | ;; especially important for the `default' face. | |
30 | ;; | |
31 | ;; Each face-remapping definition in `face-remapping-alist' added by | |
32 | ;; this code uses the form: | |
33 | ;; | |
34 | ;; (face RELATIVE_SPECS_1 RELATIVE_SPECS_2 ... BASE_SPECS) | |
35 | ;; | |
36 | ;; The "specs" values are a lists of face names or face attribute-value | |
37 | ;; pairs, and are merged together, with earlier values taking precedence. | |
38 | ;; | |
e40a85cd MB |
39 | ;; The RELATIVE_SPECS_* values are added by `face-remap-add-relative' |
40 | ;; (and removed by `face-remap-remove-relative', and are intended for | |
9d3d42fb MB |
41 | ;; face "modifications" (such as increasing the size). Typical users of |
42 | ;; relative specs would be minor modes. | |
43 | ;; | |
44 | ;; BASE_SPECS is the lowest-priority value, and by default is just the | |
45 | ;; face name, which causes the global definition of that face to be used. | |
46 | ;; | |
47 | ;; A non-default value of BASE_SPECS may also be set using | |
e40a85cd | 48 | ;; `face-remap-set-base'. Because this _overwrites_ the default |
9d3d42fb | 49 | ;; value inheriting from the global face definition, it is up to the |
e40a85cd MB |
50 | ;; caller of face-remap-set-base to add such inheritance if it is |
51 | ;; desired. A typical use of face-remap-set-base would be a major | |
9d3d42fb MB |
52 | ;; mode setting face remappings, e.g., of the default face. |
