| 99 | |
| 3027 | 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. | |
| 224 | |
| 225 If PROPERTY does not name a built-in property, its value will | |
| 226 simply be returned unless it is a specifier object, in which case | |
| 227 it will be instanced using `specifier-instance'. | |

| 261 | |
| 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 | 315 automatically be converted into a `generic' specifier. |

| 428 | 1205 "Make FACE bold in LOCALE, if possible. |
| 872 | 1206 This will attempt to make the font bold for window-system locales and will |
| 1207 set the highlight flag for TTY locales. | |
| 1208 | |
| 1209 The actual behavior of this function is somewhat messy, in an attempt to | |
| 1210 get more intuitive behavior in quite a lot of different circumstances. (You | |
| 1211 might view this as indicative of design failures with specifiers, but in | |
| 1212 fact almost all code that attempts to interface to humans and produce | |
| 1213 \"intuitive\" results gets messy, particularly with a system as complicated | |
| 1214 as specifiers, whose complexity results from an attempt to work well in | |
| 1215 many different circumstances.) | |
| 1216 | |
| 1217 The meaning of LOCALE is the same as for `specifier-spec-list', i.e.: | |
| 1218 | |
| 1219 -- If LOCALE is nil, omitted, or `all', this will attempt to \"frob\" all | |
| 1220 font specifications for FACE to make them appear bold (i.e. the | |
| 1221 specifications are replaced with equivalent specifications, where the | |
| 1222 font names have been changed to the closest bold font). | |
| 1223 | |
| 1224 -- If LOCALE is a locale type \(`buffer', `window', etc.), this frobs all | |
| 1225 font specifications for locales of that type. | |
| 1226 | |
| 1227 -- If LOCALE is a particular locale, this frobs all font specifications for | |
| 1228 that locale. | |
| 428 | 1229 |
| 872 | 1230 If TAGS is given, this only processes instantiators whose tag set includes |
| 1231 all tags mentioned in TAGS. In addition, if EXACT-P is non-nil, only | |
| 1232 instantiators whose tag set exactly matches TAGS are processed; otherwise, | |
| 1233 additional tags may be present in the instantiator's tag set. | |
| 1234 | |
| 1235 This function proceeeds in three stages. | |
| 1236 | |
| 1237 STAGE 1: Frob the settings that are already present. | |
| 1238 STAGE 2: (if called for) Ensure that *some* setting exists in the locale | |
| 1239 that was given, finding it in various ways and frobbing it as in | |
| 1240 stage 1. This ensures that there is an actual setting for | |
| 1241 the locale, so you will get the expected buffer-local/frame-local | |
| 1242 behavior -- changes to the global value, to other locales, won't | |
| 1243 affect this locale, (b) the face will actually look bold in | |
| 1244 the locale. | |
| 1137 | 1245 STAGE 3: (if called for) |
| 872 | 1246 |
| 1247 The way the frobbing works depends on the device type -- first on whether | |
| 1248 or not it's TTY, and second, if it's a window-system device type, on which | |
| 1249 particular window-system device type. For locales with a specific device | |
| 1250 type, we do the frobbing in the context of that device type -- this means | |
| 1251 that for TTY device types we set the highlight flag, and for window-system | |
| 1252 device types we modify the font spec according to the rules for font specs | |
| 1253 of that device type. For global locales, we may process both the highlight | |
| 1254 flag and the font specs (depending on the device types compiled into this | |
| 1255 XEmacs). When processing font specs, we check the tag set associated with | |
| 1256 each font spec to see if it's specific to a particular device type; if so, | |
| 1257 we frob it in the context of that type, else we use the type of the current | |
| 1258 device. (A hack, but works well in practice -- and if a new device is | |
| 1259 created, we will automatically frob all the standard fonts to make sure | |
| 1260 they display OK on that device.) | |
| 1261 | |
| 1262 If LOCALE is not a locale type, and both TAGS and EXACT-P are omitted, we | |
| 1263 do further frobbing in an attempt to give more intuitive behavior. | |
| 428 | 1264 |
| 872 | 1265 First, if there are no specifications in LOCALE (if LOCALE is `all', we act |
| 1266 as if it were `global' for this step), we do our utmost to put a | |
| 1267 specification there; otherwise, this function will have no effect. For | |
| 1268 device, frame, or window locales, the face's font is instantiated using the | |
| 1269 locale as a domain, and the resulting font is frobbed and added back as a | |
| 1270 specification for this locale. If LOCALE is `global', we retrieve the | |
| 1271 fallback specs and frob them. If LOCALE is a buffer, things get tricky | |
| 1272 since you can't instantiate a specifier in a buffer domain \(the buffer can | |
| 1273 appear in multiple places, or in different places over time, so this | |
| 1274 operation is not well-defined). We used to signal an error in this case, | |
| 1275 but now we instead try to do something logical so that we work somewhat | |
| 1276 similarly to buffer-local variables. Specifically, we use | |
| 1277 `get-buffer-window' to find a window viewing the buffer, and if there is | |
| 1278 one, use this as a domain to instantiate the font, and frob the resulting | |
| 1279 value. Otherwise, we use the selected window for the same purpose. | |
| 1280 | |
| 1281 Finally, if the frobbing didn't actually make the font look any different | |
| 1282 in whatever domain we instantiated the font in (this happens, for example, | |
| 1283 if your font specification is already bold or has no bold equivalent; note | |
| 1284 that in this step, we use the selected device in place of `global' or `all' | |
| 1285 -- another hack, but works well in practice since there's usually only one | |
| 1286 device), and the font currently looks like the font of the `default' face, | |
| 1287 it is set to inherit from the `bold' face. | |
| 1288 | |
| 1289 NOTE: For the other functions defined below, the identity of these two | |
| 1290 standard faces mentioned in the previous paragraph, and the TTY properties | |
| 1291 that are modified, may be different, and whether the TTY property or | |
| 1292 properties are set or unset may be different. For example, for | |
| 1293 `make-face-unitalic', the last sentence in the previous paragraph would | |
| 1294 read \"... and the font currently looks like the font of the `italic' face, | |
| 1295 it is set to inherit from the `default' face.\", and the second sentence in | |
| 1296 the first paragraph would read \"This will attempt to make the font | |
| 1297 non-italic for window-system locales and will unset the underline flag for | |
| 1298 TTY locales.\" | |
