|
98
|
|
|
99 If LOCALE is omitted, the FACE's actual value for PROPERTY will be
|
|
|
100 returned. For built-in properties, this will be a specifier object
|
|
|
101 of a type appropriate to the property (e.g. a font or color
|
|
|
102 specifier). For other properties, this could be anything.
|
|
|
103
|
|
|
104 If LOCALE is supplied, then instead of returning the actual value,
|
|
|
105 the specification(s) for the given locale or locale type will
|
|
|
106 be returned. This will only work if the actual value of
|
|
|
107 PROPERTY is a specifier (this will always be the case for built-in
|
|
|
108 properties, but not or not may apply to user-defined properties).
|
|
|
109 If the actual value of PROPERTY is not a specifier, this value
|
|
|
110 will simply be returned regardless of LOCALE.
|
|
|
111
|
|
|
112 The return value will be a list of instantiators (e.g. strings
|
|
|
113 specifying a font or color name), or a list of specifications, each
|
|
|
114 of which is a cons of a locale and a list of instantiators.
|
|
|
115 Specifically, if LOCALE is a particular locale (a buffer, window,
|
|
|
116 frame, device, or 'global), a list of instantiators for that locale
|
|
|
117 will be returned. Otherwise, if LOCALE is a locale type (one of
|
|
|
118 the symbols 'buffer, 'window, 'frame, or 'device), the specifications
|
|
|
119 for all locales of that type will be returned. Finally, if LOCALE is
|
|
|
120 'all, the specifications for all locales of all types will be returned.
|
|
|
121
|
|
|
122 The specifications in a specifier determine what the value of
|
|
|
123 PROPERTY will be in a particular \"domain\" or set of circumstances,
|
|
|
124 which is typically a particular Emacs window along with the buffer
|
|
442
|
125 it contains and the frame and device it lies within. The value is
|
|
|
126 derived from the instantiator associated with the most specific
|
|
428
|
127 locale (in the order buffer, window, frame, device, and 'global)
|
|
|
128 that matches the domain in question. In other words, given a domain
|
|
442
|
129 (i.e. an Emacs window, usually), the specifier for PROPERTY will
|
|
|
130 first be searched for a specification whose locale is the buffer
|
|
|
131 contained within that window; then for a specification whose locale
|
|
|
132 is the window itself; then for a specification whose locale is the
|
|
|
133 frame that the window is contained within; etc. The first
|
|
|
134 instantiator that is valid for the domain (usually this means that
|
|
|
135 the instantiator is recognized by the device [i.e. MS Windows, the X
|
|
|
136 server or TTY device] that the domain is on. The function
|
|
|
137 `face-property-instance' actually does all this, and is used to
|
|
|
138 determine how to display the face.

172 Under most circumstances, DOMAIN will be a particular window,
|
|
|
173 and the returned instance describes how the specified property
|
|
|
174 actually is displayed for that window and the particular buffer
|
|
|
175 in it. Note that this may not be the same as how the property
|
|
|
176 appears when the buffer is displayed in a different window or
|
|
|
177 frame, or how the property appears in the same window if you
|
|
|
178 switch to another buffer in that window; and in those cases,
|
|
|
179 the returned instance would be different.
|
|
|
180
|
|
|
181 The returned instance will typically be a color-instance,
|
|
|
182 font-instance, or pixmap-instance object, and you can query
|
|
|
183 it using the appropriate object-specific functions. For example,
|
|
|
184 you could use `color-instance-rgb-components' to find out the
|
|
|
185 RGB (red, green, and blue) components of how the 'background
|
|
|
186 property of the 'highlight face is displayed in a particular
|
|
|
187 window. The results might be different from the results
|
|
|
188 you would get for another window (perhaps the user
|
|
|
189 specified a different color for the frame that window is on;
|
|
|
190 or perhaps the same color was specified but the window is
|
|
|
191 on a different X server, and that X server has different RGB
|
|
|
192 values for the color from this one).
|
|
|
193
|
|
|
194 DOMAIN defaults to the selected window if omitted.
|
|
|
195
|
|
|
196 DOMAIN can be a frame or device, instead of a window. The value
|
|
|
197 returned for a such a domain is used in special circumstances
|
|
|
198 when a more specific domain does not apply; for example, a frame
|
|
|
199 value might be used for coloring a toolbar, which is conceptually
|
|
|
200 attached to a frame rather than a particular window. The value
|
|
|
201 is also useful in determining what the value would be for a
|
|
|
202 particular window within the frame or device, if it is not
|
|
|
203 overridden by a more specific specification.

252 NOTE: If you want to remove a property from a face, use `remove-face-property'
|
|
|
253 rather than attempting to set a value of nil for the property.
|
|
|
254
|
|
|
255 For built-in properties, the actual value of the property is a
|
|
|
256 specifier and you cannot change this; but you can change the
|
|
|
257 specifications within the specifier, and that is what this function
|
|
|
258 will do. For user-defined properties, you can use this function
|
|
|
259 to either change the actual value of the property or, if this value
|
|
|
260 is a specifier, change the specifications within it.
|
|
|
261
|
|
|
262 If PROPERTY is a built-in property, the specifications to be added to
|
|
|
263 this property can be supplied in many different ways:
|
|
|
264
|
|
|
265 -- If VALUE is a simple instantiator (e.g. a string naming a font or
|
|
|
266 color) or a list of instantiators, then the instantiator(s) will
|
|
|
267 be added as a specification of the property for the given LOCALE
|
|
|
268 (which defaults to 'global if omitted).
|
|
|
269 -- If VALUE is a list of specifications (each of which is a cons of
|
|
|
270 a locale and a list of instantiators), then LOCALE must be nil
|
|
|
271 (it does not make sense to explicitly specify a locale in this
|
|
|
272 case), and specifications will be added as given.
|
|
|
273 -- If VALUE is a specifier (as would be returned by `face-property'
|
|
|
274 if no LOCALE argument is given), then some or all of the
|
|
|
275 specifications in the specifier will be added to the property.
|
|
|
276 In this case, the function is really equivalent to
|
|
|
277 `copy-specifier' and LOCALE has the same semantics (if it is
|
|
|
278 a particular locale, the specification for the locale will be
|
|
|
279 copied; if a locale type, specifications for all locales of
|
|
|
280 that type will be copied; if nil or 'all, then all
|
|
|
281 specifications will be copied).
|
|
|
282
|
|
|
283 HOW-TO-ADD should be either nil or one of the symbols 'prepend,
|
|
|
284 'append, 'remove-tag-set-prepend, 'remove-tag-set-append, 'remove-locale,
|
|
|
285 'remove-locale-type, or 'remove-all. See `copy-specifier' and
|
|
|
286 `add-spec-to-specifier' for a description of what each of
|
|
|
287 these means. Most of the time, you do not need to worry about
|
|
|
288 this argument; the default behavior usually is fine.
|
|
|
289
|
|
|
290 In general, it is OK to pass an instance object (e.g. as returned
|
|
|
291 by `face-property-instance') as an instantiator in place of
|
|
|
292 an actual instantiator. In such a case, the instantiator used
|
|
|
293 to create that instance object will be used (for example, if
|
|
|
294 you set a font-instance object as the value of the 'font
|
|
|
295 property, then the font name used to create that object will
|
|
|
296 be used instead). If some cases, however, doing this
|
|
|
297 conversion does not make sense, and this will be noted in
|
|
|
298 the documentation for particular types of instance objects.
|
|
|
299
|
|
|
300 If PROPERTY is not a built-in property, then this function will
|
|
|
301 simply set its value if LOCALE is nil. However, if LOCALE is
|
|
|
302 given, then this function will attempt to add VALUE as the
|
|
|
303 instantiator for the given LOCALE, using `add-spec-to-specifier'.
|
|
|
304 If the value of the property is not a specifier, it will
|
|
|
305 automatically be converted into a 'generic specifier.

1124 The actual behavior of this function is somewhat messy, in an attempt to
|
|
|
1125 get more intuitive behavior in quite a lot of different circumstances. (You
|
|
|
1126 might view this as indicative of design failures with specifiers, but in
|
|
|
1127 fact almost all code that attempts to interface to humans and produce
|
|
|
1128 \"intuitive\" results gets messy, particularly with a system as complicated
|
|
|
1129 as specifiers, whose complexity results from an attempt to work well in
|
|
|
1130 many different circumstances.)
|
|
|
1131
|
|
|
1132 The meaning of LOCALE is the same as for `specifier-spec-list', i.e.:
|
|
|
1133
|
|
|
1134 -- If LOCALE is nil, omitted, or `all', this will attempt to \"frob\" all
|
|
|
1135 font specifications for FACE to make them appear bold (i.e. the
|
|
|
1136 specifications are replaced with equivalent specifications, where the
|
|
|
1137 font names have been changed to the closest bold font).
|
|
|
1138
|
|
|
1139 -- If LOCALE is a locale type \(`buffer', `window', etc.), this frobs all
|
|
|
1140 font specifications for locales of that type.
|
|
|
1141
|
|
|
1142 -- If LOCALE is a particular locale, this frobs all font specifications for
|
|
|
1143 that locale.
|
|
428
|
1144
|
|
872
|
1145 If TAGS is given, this only processes instantiators whose tag set includes
|
|
|
1146 all tags mentioned in TAGS. In addition, if EXACT-P is non-nil, only
|
|
|
1147 instantiators whose tag set exactly matches TAGS are processed; otherwise,
|
|
|
1148 additional tags may be present in the instantiator's tag set.
|
|
|
1149
|
|
|
1150 This function proceeeds in three stages.
|
|
|
1151
|
|
|
1152 STAGE 1: Frob the settings that are already present.
|
|
|
1153 STAGE 2: (if called for) Ensure that *some* setting exists in the locale
|
|
|
1154 that was given, finding it in various ways and frobbing it as in
|
|
|
1155 stage 1. This ensures that there is an actual setting for
|
|
|
1156 the locale, so you will get the expected buffer-local/frame-local
|
|
|
1157 behavior -- changes to the global value, to other locales, won't
|
|
|
1158 affect this locale, (b) the face will actually look bold in
|
|
|
1159 the locale.
|
|
1137
|
1160 STAGE 3: (if called for)
|
|
872
|
1161
|
|
|
1162 The way the frobbing works depends on the device type -- first on whether
|
|
|
1163 or not it's TTY, and second, if it's a window-system device type, on which
|
|
|
1164 particular window-system device type. For locales with a specific device
|
|
|
1165 type, we do the frobbing in the context of that device type -- this means
|
|
|
1166 that for TTY device types we set the highlight flag, and for window-system
|
|
|
1167 device types we modify the font spec according to the rules for font specs
|
|
|
1168 of that device type. For global locales, we may process both the highlight
|
|
|
1169 flag and the font specs (depending on the device types compiled into this
|
|
|
1170 XEmacs). When processing font specs, we check the tag set associated with
|
|
|
1171 each font spec to see if it's specific to a particular device type; if so,
|
|
|
1172 we frob it in the context of that type, else we use the type of the current
|
|
|
1173 device. (A hack, but works well in practice -- and if a new device is
|
|
|
1174 created, we will automatically frob all the standard fonts to make sure
|
|
|
1175 they display OK on that device.)
|
|
|
1176
|
|
|
1177 If LOCALE is not a locale type, and both TAGS and EXACT-P are omitted, we
|
|
|
1178 do further frobbing in an attempt to give more intuitive behavior.
|
|
428
|
1179
|
|
872
|
1180 First, if there are no specifications in LOCALE (if LOCALE is `all', we act
|
|
|
1181 as if it were `global' for this step), we do our utmost to put a
|
|
|
1182 specification there; otherwise, this function will have no effect. For
|
|
|
1183 device, frame, or window locales, the face's font is instantiated using the
|
|
|
1184 locale as a domain, and the resulting font is frobbed and added back as a
|
|
|
1185 specification for this locale. If LOCALE is `global', we retrieve the
|
|
|
1186 fallback specs and frob them. If LOCALE is a buffer, things get tricky
|
|
|
1187 since you can't instantiate a specifier in a buffer domain \(the buffer can
|
|
|
1188 appear in multiple places, or in different places over time, so this
|
|
|
1189 operation is not well-defined). We used to signal an error in this case,
|
|
|
1190 but now we instead try to do something logical so that we work somewhat
|
|
|
1191 similarly to buffer-local variables. Specifically, we use
|
|
|
1192 `get-buffer-window' to find a window viewing the buffer, and if there is
|
|
|
1193 one, use this as a domain to instantiate the font, and frob the resulting
|
|
|
1194 value. Otherwise, we use the selected window for the same purpose.
|
|
|
1195
|
|
|
1196 Finally, if the frobbing didn't actually make the font look any different
|
|
|
1197 in whatever domain we instantiated the font in (this happens, for example,
|
|
|
1198 if your font specification is already bold or has no bold equivalent; note
|
|
|
1199 that in this step, we use the selected device in place of `global' or `all'
|
|
|
1200 -- another hack, but works well in practice since there's usually only one
|
|
|
1201 device), and the font currently looks like the font of the `default' face,
|
|
|
1202 it is set to inherit from the `bold' face.
|
|
|
1203
|
|
|
1204 NOTE: For the other functions defined below, the identity of these two
|
|
|
1205 standard faces mentioned in the previous paragraph, and the TTY properties
|
|
|
1206 that are modified, may be different, and whether the TTY property or
|
|
|
1207 properties are set or unset may be different. For example, for
|
|
|
1208 `make-face-unitalic', the last sentence in the previous paragraph would
|
|
|
1209 read \"... and the font currently looks like the font of the `italic' face,
|
|
|
1210 it is set to inherit from the `default' face.\", and the second sentence in
|
|
|
1211 the first paragraph would read \"This will attempt to make the font
|
|
|
1212 non-italic for window-system locales and will unset the underline flag for
|
|
|
1213 TTY locales.\"
