100 NOTE: If you are looking for the \"value\" of a built-in face property
|
|
|
101 (`foreground', `background', `font', `background-pixmap', etc.), you
|
|
|
102 are probably better off calling `face-property-instance'. The return
|
|
|
103 value of `face-property' for built-in properties describes the original
|
|
|
104 specification used to determine the face property, which may be nil,
|
|
|
105 a list of instantiators, or something else that is unexpected. For
|
|
|
106 example, if you ask for a face property in a particular buffer (by
|
|
|
107 specifying a buffer for LOCALE), you will get a non-nil return value
|
|
|
108 only if a buffer-local specification for that particular buffer had
|
|
|
109 previously been given.
|
|
|
110
|
|
|
111 For a full list of built-in property names and their semantics, see
|
|
|
112 `set-face-property'.
|
|
428
|
113
|
|
3027
|
114 If LOCALE is omitted, the FACE's actual value for PROPERTY will be
|
|
|
115 returned. In this case, this function appears to behave rather
|
|
|
116 differently depending on whether PROPERTY is a built-in face property of
|
|
|
117 a user-defined face property. This is because the most basic value of a
|
|
|
118 user-defined property is simply whatever was set using
|
|
|
119 `set-face-property', but for a built-in property it's always a specifier,
|
|
|
120 which is an abstract object encapsulating all the specifications for that
|
|
|
121 particular property.
|
|
|
122
|
|
|
123 LOCALE, if supplied, will generally be a buffer, frame or
|
|
|
124 `global' (for the global value), but there are other possibilities -- see
|
|
|
125 the following paragraph. This mostly applies to built-in properties. In
|
|
|
126 this case, the return value will not be a specifier object but the
|
|
|
127 specification(s) for the given locale or locale type will be returned
|
|
|
128 (equivalent to calling `specifier-specs' on the specifier).
|
|
|
129 (Technically, the same thing happens if the basic value of a user-
|
|
|
130 defined property is a specifier, although this usage is rare.)
|
|
428
|
131
|
|
|
132 The return value will be a list of instantiators (e.g. strings
|
|
|
133 specifying a font or color name), or a list of specifications, each
|
|
|
134 of which is a cons of a locale and a list of instantiators.
|
|
|
135 Specifically, if LOCALE is a particular locale (a buffer, window,
|
|
3027
|
136 frame, device, or `global'), a list of instantiators for that locale
|
|
428
|
137 will be returned. Otherwise, if LOCALE is a locale type (one of
|
|
3027
|
138 the symbols `buffer', `window', `frame', or `device'), the specifications
|
|
428
|
139 for all locales of that type will be returned. Finally, if LOCALE is
|
|
3027
|
140 `all', the specifications for all locales of all types will be returned.
|
|
428
|
141
|
|
|
142 The specifications in a specifier determine what the value of
|
|
|
143 PROPERTY will be in a particular \"domain\" or set of circumstances,
|
|
3027
|
144 which is typically a particular Emacs window -- which in turn defines
|
|
|
145 a buffer (the buffer in the window), a frame (the frame that the window
|
|
|
146 is in), and a device (the device that the frame is in). The value is
|
|
442
|
147 derived from the instantiator associated with the most specific
|
|
3027
|
148 locale (in the order buffer, window, frame, device, and `global')
|
|
428
|
149 that matches the domain in question. In other words, given a domain
|
|
442
|
150 (i.e. an Emacs window, usually), the specifier for PROPERTY will
|
|
|
151 first be searched for a specification whose locale is the buffer
|
|
|
152 contained within that window; then for a specification whose locale
|
|
|
153 is the window itself; then for a specification whose locale is the
|
|
|
154 frame that the window is contained within; etc. The first
|
|
|
155 instantiator that is valid for the domain (usually this means that
|
|
|
156 the instantiator is recognized by the device [i.e. MS Windows, the X
|
|
3027
|
157 server or TTY device]) will be \"instantiated\", which generates
|
|
|
158 a Lisp object encapsulating the original instantiator and the underlying
|
|
|
159 window-system object describing the property. The function
|
|
|
160 `face-property-instance' actually does all this."

191
|
|
|
192 Under most circumstances, DOMAIN will be a particular window,
|
|
|
193 and the returned instance describes how the specified property
|
|
|
194 actually is displayed for that window and the particular buffer
|
|
|
195 in it. Note that this may not be the same as how the property
|
|
|
196 appears when the buffer is displayed in a different window or
|
|
|
197 frame, or how the property appears in the same window if you
|
|
|
198 switch to another buffer in that window; and in those cases,
|
|
|
199 the returned instance would be different.
|
|
|
200
|
|
|
201 The returned instance will typically be a color-instance,
|
|
3027
|
202 font-instance, or image-instance object, and you can query
|
|
428
|
203 it using the appropriate object-specific functions. For example,
|
|
|
204 you could use `color-instance-rgb-components' to find out the
|
|
3027
|
205 RGB (red, green, and blue) components of how the `background'
|
|
|
206 property of the `highlight' face is displayed in a particular
|
|
428
|
207 window. The results might be different from the results
|
|
|
208 you would get for another window (perhaps the user
|
|
|
209 specified a different color for the frame that window is on;
|
|
|
210 or perhaps the same color was specified but the window is
|
|
|
211 on a different X server, and that X server has different RGB
|
|
|
212 values for the color from this one).
|
|
|
213
|
|
|
214 DOMAIN defaults to the selected window if omitted.
|
|
|
215
|
|
|
216 DOMAIN can be a frame or device, instead of a window. The value
|
|
|
217 returned for a such a domain is used in special circumstances
|
|
|
218 when a more specific domain does not apply; for example, a frame
|
|
|
219 value might be used for coloring a toolbar, which is conceptually
|
|
|
220 attached to a frame rather than a particular window. The value
|
|
|
221 is also useful in determining what the value would be for a
|
|
|
222 particular window within the frame or device, if it is not

223 overridden by a more specific specification.

262 NOTE: If you want to remove a property from a face, use `remove-face-property'

|
263 rather than attempting to set a value of nil for the property.
|
|
|
264
|
|
|
265 For built-in properties, the actual value of the property is a
|
|
|
266 specifier and you cannot change this; but you can change the
|
|
|
267 specifications within the specifier, and that is what this function
|
|
|
268 will do. For user-defined properties, you can use this function
|
|
|
269 to either change the actual value of the property or, if this value
|
|
|
270 is a specifier, change the specifications within it.
|
|
|
271
|
|
|
272 If PROPERTY is a built-in property, the specifications to be added to
|
|
|
273 this property can be supplied in many different ways:
|
|
|
274
|
|
|
275 -- If VALUE is a simple instantiator (e.g. a string naming a font or
|
|
|
276 color) or a list of instantiators, then the instantiator(s) will
|
|
|
277 be added as a specification of the property for the given LOCALE
|
|
3027
|
278 (which defaults to `global' if omitted).
|
|
428
|
279 -- If VALUE is a list of specifications (each of which is a cons of
|
|
|
280 a locale and a list of instantiators), then LOCALE must be nil
|
|
|
281 (it does not make sense to explicitly specify a locale in this
|
|
|
282 case), and specifications will be added as given.
|
|
|
283 -- If VALUE is a specifier (as would be returned by `face-property'
|
|
|
284 if no LOCALE argument is given), then some or all of the
|
|
|
285 specifications in the specifier will be added to the property.
|
|
|
286 In this case, the function is really equivalent to
|
|
|
287 `copy-specifier' and LOCALE has the same semantics (if it is
|
|
|
288 a particular locale, the specification for the locale will be
|
|
|
289 copied; if a locale type, specifications for all locales of
|
|
3027
|
290 that type will be copied; if nil or `all', then all
|
|
428
|
291 specifications will be copied).
|
|
|
292
|
|
3027
|
293 HOW-TO-ADD should be either nil or one of the symbols `prepend',
|
|
|
294 `append', `remove-tag-set-prepend', `remove-tag-set-append', `remove-locale',
|
|
|
295 `remove-locale-type', or `remove-all'. See `copy-specifier' and
|
|
428
|
296 `add-spec-to-specifier' for a description of what each of
|
|
|
297 these means. Most of the time, you do not need to worry about
|
|
|
298 this argument; the default behavior usually is fine.
|
|
|
299
|
|
|
300 In general, it is OK to pass an instance object (e.g. as returned
|
|
|
301 by `face-property-instance') as an instantiator in place of
|
|
|
302 an actual instantiator. In such a case, the instantiator used
|
|
|
303 to create that instance object will be used (for example, if
|
|
3027
|
304 you set a font-instance object as the value of the `font'
|
|
428
|
305 property, then the font name used to create that object will
|
|
|
306 be used instead). If some cases, however, doing this
|
|
|
307 conversion does not make sense, and this will be noted in
|
|
|
308 the documentation for particular types of instance objects.
|
|
|
309
|
|
|
310 If PROPERTY is not a built-in property, then this function will
|
|
|
311 simply set its value if LOCALE is nil. However, if LOCALE is
|
|
|
312 given, then this function will attempt to add VALUE as the
|
|
|
313 instantiator for the given LOCALE, using `add-spec-to-specifier'.
|
|
|
314 If the value of the property is not a specifier, it will
|
|
3027
|

936 ;; instantiator as appropriate for the device type (this includes TTY's),

952 ;; sensible with buffer locales, or many other things. (It always, or

954 ;; do three things we don't:
|
|
|
955 ;;
|
|
|
956 ;; (1) Map over all devices when processing global or buffer locales.
|
|
|
957 ;; Should we be doing this in stages 2 and/or 3? The fact that we
|
|
|
958 ;; now process all fallback instantiators seems to make this less
|
|
|
959 ;; necessary, at least for global locales.
|
|
|
960 ;;
|
|
|
961 ;; (2) Remove all instantiators tagged with `default' when putting the
|
|
|
962 ;; instantiators back. I don't see why this is necessary, but maybe
|
|
|
963 ;; it is.
|
|
|
964 ;;
|

965 ;; (3) Pay attention to the face-frob-from-locale-first variable. ####

1207 The actual behavior of this function is somewhat messy, in an attempt to

1209 might view this as indicative of design failures with specifiers, but in
|
|
|
1210 fact almost all code that attempts to interface to humans and produce
|
|
|
1211 \"intuitive\" results gets messy, particularly with a system as complicated
|
|
|
1212 as specifiers, whose complexity results from an attempt to work well in
|
|
|
1213 many different circumstances.)
|
|
|
1214
|
|
|
1215 The meaning of LOCALE is the same as for `specifier-spec-list', i.e.:
|
|
|
1216
|
|
|
1217 -- If LOCALE is nil, omitted, or `all', this will attempt to \"frob\" all
|
|
|
1218 font specifications for FACE to make them appear bold (i.e. the
|
|
|
1219 specifications are replaced with equivalent specifications, where the
|
|
|
1220 font names have been changed to the closest bold font).
|
|
|
1221
|
|
|
1222 -- If LOCALE is a locale type \(`buffer', `window', etc.), this frobs all
|
|
|
1223 font specifications for locales of that type.
|
|
|
1224
|
|
|
1225 -- If LOCALE is a particular locale, this frobs all font specifications for
|

1226 that locale.

872
|
1228 If TAGS is given, this only processes instantiators whose tag set includes
|
|
|
1229 all tags mentioned in TAGS. In addition, if EXACT-P is non-nil, only
|
|
|
1230 instantiators whose tag set exactly matches TAGS are processed; otherwise,
|
|
|
1231 additional tags may be present in the instantiator's tag set.
|
|
|
1232
|
|
|
1233 This function proceeeds in three stages.
|
|
|
1234
|
|
|
1235 STAGE 1: Frob the settings that are already present.
|
|
|
1236 STAGE 2: (if called for) Ensure that *some* setting exists in the locale
|
|
|
1237 that was given, finding it in various ways and frobbing it as in
|
|
|
1238 stage 1. This ensures that there is an actual setting for
|
|
|
1239 the locale, so you will get the expected buffer-local/frame-local
|
|
|
1240 behavior -- changes to the global value, to other locales, won't
|
|
|
1241 affect this locale, (b) the face will actually look bold in
|
|
|
1242 the locale.

1243 STAGE 3: (if called for)
|
|
872
|
1244
|
|
|
1245 The way the frobbing works depends on the device type -- first on whether
|
|
|
1246 or not it's TTY, and second, if it's a window-system device type, on which
|
|
|
1247 particular window-system device type. For locales with a specific device
|
|
|
1248 type, we do the frobbing in the context of that device type -- this means
|
|
|
1249 that for TTY device types we set the highlight flag, and for window-system
|
|
|
1250 device types we modify the font spec according to the rules for font specs
|
|
|
1251 of that device type. For global locales, we may process both the highlight
|
|
|
1252 flag and the font specs (depending on the device types compiled into this
|
|
|
1253 XEmacs). When processing font specs, we check the tag set associated with
|
|
|
1254 each font spec to see if it's specific to a particular device type; if so,
|
|
|
1255 we frob it in the context of that type, else we use the type of the current
|
|
|
1256 device. (A hack, but works well in practice -- and if a new device is
|
|
|
1257 created, we will automatically frob all the standard fonts to make sure
|
|
|
1258 they display OK on that device.)
|
|
|
1259
|
|
|
1260 If LOCALE is not a locale type, and both TAGS and EXACT-P are omitted, we
|
|
|
1261 do further frobbing in an attempt to give more intuitive behavior.
|
|
428
|
1262
|
|
872
|
1263 First, if there are no specifications in LOCALE (if LOCALE is `all', we act
|
|
|
1264 as if it were `global' for this step), we do our utmost to put a
|
|
|
1265 specification there; otherwise, this function will have no effect. For
|
|
|
1266 device, frame, or window locales, the face's font is instantiated using the
|
|
|
1267 locale as a domain, and the resulting font is frobbed and added back as a
|
|
|
1268 specification for this locale. If LOCALE is `global', we retrieve the
|
|
|
1269 fallback specs and frob them. If LOCALE is a buffer, things get tricky
|
|
|
1270 since you can't instantiate a specifier in a buffer domain \(the buffer can
|
|
|
1271 appear in multiple places, or in different places over time, so this
|
|
|
1272 operation is not well-defined). We used to signal an error in this case,
|
|
|
1273 but now we instead try to do something logical so that we work somewhat
|
|
|
1274 similarly to buffer-local variables. Specifically, we use
|
|
|
1275 `get-buffer-window' to find a window viewing the buffer, and if there is
|
|
|
1276 one, use this as a domain to instantiate the font, and frob the resulting
|
|
|
1277 value. Otherwise, we use the selected window for the same purpose.
|
|
|
1278
|
|
|
1279 Finally, if the frobbing didn't actually make the font look any different
|
|
|
1280 in whatever domain we instantiated the font in (this happens, for example,
|
|
|
1281 if your font specification is already bold or has no bold equivalent; note
|
|
|
1282 that in this step, we use the selected device in place of `global' or `all'
|
|
|
1283 -- another hack, but works well in practice since there's usually only one
|
|
|
1284 device), and the font currently looks like the font of the `default' face,
|
|
|
1285 it is set to inherit from the `bold' face.
|
|
|
1286
|
|
|
1287 NOTE: For the other functions defined below, the identity of these two
|
|
|
1288 standard faces mentioned in the previous paragraph, and the TTY properties
|
|
|
1289 that are modified, may be different, and whether the TTY property or
|
|
|
1290 properties are set or unset may be different. For example, for
|
|
|
1291 `make-face-unitalic', the last sentence in the previous paragraph would
|
|
|
1292 read \"... and the font currently looks like the font of the `italic' face,
|
|
|
1293 it is set to inherit from the `default' face.\", and the second sentence in
|
|
|
1294 the first paragraph would read \"This will attempt to make the font
|
|
|
1295 non-italic for window-system locales and will unset the underline flag for
|
|
|
1296 TTY locales.\"
|
|
|
