221 is no longer in use. For all but windows, "no longer in use"
|

222 corresponds exactly to when the object is deleted (non-deleted

223 objects are always held permanently in special lists, and deleted
|
|
|
224 objects are never on these lists and never reusable). To handle
|
|

225 this, we just have cleanup_specifiers() called periodically

226 (at the beginning of garbage collection); it removes all dead
|
|
|
227 objects.
|
|
|
228
|
|
|
229 For windows, however, it's trickier because dead objects can be
|
|
|
230 converted to live ones again if the dead object is in a window
|
|
|
231 configuration. Therefore, for windows, "no longer in use"
|
|
|
232 corresponds to when the window object is garbage-collected.
|
|

233 We now use weak lists for this purpose.

578
|
|
|
579 A specifier is an object that can be used to keep track of a property
|
|
|
580 whose value can be per-buffer, per-window, per-frame, or per-device,
|
|
442
|
581 and can further be restricted to a particular console-type or
|
|
|
582 device-class. Specifiers are used, for example, for the various
|
|
|
583 built-in properties of a face; this allows a face to have different
|
|
|
584 values in different frames, buffers, etc.
|
|
|
585
|
|
|
586 When speaking of the value of a specifier, it is important to
|
|
|
587 distinguish between the *setting* of a specifier, called an
|
|
|
588 \"instantiator\", and the *actual value*, called an \"instance\". You
|
|
|
589 put various possible instantiators (i.e. settings) into a specifier
|
|
|
590 and associate them with particular locales (buffer, window, frame,
|
|
|
591 device, global), and then the instance (i.e. actual value) is
|
|
|
592 retrieved in a specific domain (window, frame, device) by looking
|
|
|
593 through the possible instantiators (i.e. settings). This process is
|
|
|
594 called \"instantiation\".
|
|
444
|
595
|
|
442
|
596 To put settings into a specifier, use `set-specifier', or the
|
|
|
597 lower-level functions `add-spec-to-specifier' and
|
|
|
598 `add-spec-list-to-specifier'. You can also temporarily bind a setting
|
|
|
599 to a specifier using `let-specifier'. To retrieve settings, use
|
|
|
600 `specifier-specs', or its lower-level counterpart
|
|
2953
|
601 `specifier-spec-list'.
|
|
|
602
|
|
|
603 To determine the actual value (i.e. the instance) in a particular domain, use
|
|
|
604 `specifier-instance'. To determine the corresponding setting that yielded
|
|
|
605 the value (i.e. the instantiator), use `specifier-instantiator'.
|
|
442
|
606
|
|
|
607 For more information, see `set-specifier', `specifier-instance',
|
|
428
|
608 `specifier-specs', and `add-spec-to-specifier'; or, for a detailed
|
|
442
|
609 description of specifiers, including how exactly the instantiation
|
|
|
610 process works, see the chapter on specifiers in the XEmacs Lisp
|
|
|
611 Reference Manual.
|
|
428
|
612
|
|
|
613 TYPE specifies the particular type of specifier, and should be one of

2953
|
614 the symbols `generic', `integer', `natnum', `boolean', `color', `font',
|

615 `image', `face-boolean', `display-table', `gutter', `gutter-size',

838 A specifier tag set is an entity that is attached to an instantiator and can
|
|
|
839 be used to restrict the scope of that instantiator to a particular device
|
|
|
840 class, device type, or charset. It can also be used to mark instantiators
|
|
|
841 added by a particular package so that they can be later removed as a group.
|
|
428
|
842
|
|
|
843 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
844 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
845 \(The valid device types and device classes are always tags, as are
|
|
|
846 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
|
847 \(as opposed to a list) because the order of the tags or the number of
|
|
|
848 times a particular tag occurs does not matter.
|
|
|
849
|
|
3659
|
850 Each tag has two predicates associated with it, which specify, respectively,
|
|
|
851 whether that tag applies to a particular device and whether it applies to a
|
|
|
852 particular character set. The predefined tags which are device types and
|
|
|
853 classes match devices of that type or class. User-defined tags can have any
|
|
|
854 device predicate, or none (meaning that all devices match). When attempting
|
|
|
855 to instantiate a specifier, a particular instantiator is only considered if
|
|
|
856 the device of the domain being instantiated over matches all tags in the tag
|
|
|
857 set attached to that instantiator.
|
|
|
858
|
|
|
859 If a charset is to be considered--which is only the case for face
|
|
|
860 instantiators--this consideration may be done twice. The first iteration
|
|
|
861 pays attention to the character set predicates; if no instantiator can be
|
|
|
862 found in that case, the search is repeated ignoring the character set
|
|
|
863 predicates.
|
|
428
|
864
|
|
|
865 Most of the time, a tag set is not specified, and the instantiator
|
|
|
866 gets a null tag set, which matches all devices.

1227 If DEVICE-PREDICATE is specified, it should be a function of one argument

1228 \(a device) that specifies whether the tag matches that particular device.

1229 If DEVICE-PREDICATE is omitted, the tag matches all devices.
|

|
1230
|
|
|
1231 If CHARSET-PREDICATE is supplied, it should be a function taking a single
|
|
|
1232 Lisp character set argument. A tag's charset predicate is primarily used to
|
|
|
1233 determine what font to use for a given \(set of) charset\(s) when that tag
|
|
|
1234 is used in a set-face-font call; a non-nil return value indicates that the

|
1235 tag matches the charset.
|
|
|
1236
|
|
|
1237 The font matching process also has a concept of stages; the defined stages
|
|
|
1238 are currently `initial' and `final', and there exist specifier tags with
|
|
|
1239 those names that correspond to those stages. On X11, 'initial is used when
|
|
|
1240 the font matching process is looking for fonts that match the desired
|
|
|
1241 registries of the charset--see the `charset-registries' function. If that
|
|
|
1242 match process fails, then the 'final tag becomes relevant; this means that a
|
|
|
1243 more general lookup is desired, and that a font doesn't necessarily have to
|
|
|
1244 match the desired XLFD for the face, just the charset repertoire for this
|
|
|
1245 charset. It also means that the charset registry and encoding used will be
|
|
|
1246 `iso10646-1', and the characters will be converted to display using that
|
|
|
1247 registry.
|
|
|
1248
|
|
|
1249 If a tag set matches no character set; the two-stage match process will
|
|
|
1250 ignore the tag on its first pass, but if no match is found, it will respect
|
|
|
1251 it on the second pass, where character set information is ignored.
|
|
|
1252
|
|
|
1253 You can redefine an existing user-defined specifier tag. However, you
|
|

3129 DOMAIN is nearly always a window (defaulting to the selected window if
|
|
|
3130 omitted), but can be a window, frame, or device. Other values that are legal
|
|
428
|
3131 as a locale (e.g. a buffer) are not valid as a domain because they do not
|
|
|
3132 provide enough information to identify a particular device (see
|
|
2953
|
3133 `valid-specifier-domain-p'). Window domains are used internally in nearly
|
|
|
3134 all circumstances when computing specifier instances of display properties.
|
|
|
3135 Frame domains are used in a few circumstances (such as when computing the
|
|
|
3136 geometry of a frame based on properties such as the toolbar widths), and
|
|
|
3137 device domains are rarely if ever used internally.
|
|
|
3138
|
|
|
3139 This function looks through the specifications in SPECIFIER that correspond
|
|
|
3140 to DOMAIN, from most specific (specifications for DOMAIN itself) to most
|
|
|
3141 general (global specifications), for matching instantiators, and attempts
|
|
|
3142 to compute an instance value for each instantiator found. The first
|
|
|
3143 successfully computed value is returned. The corresponding instantiator
|
|
|
3144 can be returned using `specifier-instantiator'.
|
|
|
3145
|
|
|
3146 A specifier is a generalized object for controlling the value of a property --
|
|
|
3147 typically, but not necessarily, a display-related property -- that can vary
|
|
|
3148 over particular buffers, frames, device types, etc.
|
|
|
3149
|
|
|
3150 A fundamental distinction must be made between the specification of a
|
|
|
3151 property's value, and the resulting value itself. This distinction is
|
|
|
3152 clearest in the case of an image -- the specification describes the source
|
|
|
3153 of the image (for example, a file of JPEG data), and the resulting value
|
|
|
3154 encapsulates a window-system object describing the image as displayed on a
|
|
|
3155 particular device (for example, a particular X display). The specification
|
|
|
3156 might also be an instruction of the form "use the background pixmap of the
|
|
|
3157 `modeline' face". A similar mapping exists between color strings and
|
|
|
3158 color-instance objects, and font strings and font-instance objects. In
|
|
|
3159 some cases, the specification and the resulting value are of the same type,
|
|
|
3160 but the distinction is still logically made.
|
|
|
3161
|
|
|
3162 The specification of a value is called an instantiator, and the resulting
|
|
|
3163 value the instance.
|
|
428
|
3164
|
|
|
3165 "Instantiating" a specifier in a particular domain means determining
|
|
|
3166 the specifier's "value" in that domain. This is accomplished by
|
|
|
3167 searching through the specifications in the specifier that correspond
|
|
|
3168 to all locales that can be derived from the given domain, from specific
|
|
|
3169 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
3170 specifications are searched for as follows:
|
|
|
3171
|
|
|
3172 1. A specification whose locale is the window itself;
|
|
|
3173 2. A specification whose locale is the window's buffer;
|
|
|
3174 3. A specification whose locale is the window's frame;
|
|
|
3175 4. A specification whose locale is the window's frame's device;
|
|
2953
|
3176 5. A specification whose locale is `global'.
|
|
428
|
3177
|
|
|
3178 If all of those fail, then the C-code-provided fallback value for
|
|
|
3179 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
3180 an inst-list, then this function attempts to instantiate that list
|
|
|
3181 just as when a specification is located in the first five steps above.
|
|
|
3182 If the fallback is a specifier, `specifier-instance' is called
|
|
|
3183 recursively on this specifier and the return value used. Note,
|
|
|
3184 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
3185 the fallback value will not be consulted.
|
|
|
3186
|
|
|
3187 Note that there may be more than one specification matching a particular
|
|
|
3188 locale; all such specifications are considered before looking for any
|
|
|
3189 specifications for more general locales. Any particular specification
|
|
|
3190 that is found may be rejected because its tag set does not match the
|
|
|
3191 device being instantiated over, or because the specification is not
|
|
|
3192 valid for the device of the given domain (e.g. the font or color name
|
|
|
3193 does not exist for this particular X server).
|
|
|
3194
|
|
793
|
3195 NOTE: When errors occur in the process of trying a particular instantiator,
|
|
|
3196 and the instantiator is thus skipped, warnings will be issued at level
|
|
|
3197 `debug'. Normally, such warnings are ignored entirely, but you can change
|
|
|
3198 this by setting `log-warning-minimum-level'. This is useful if you're
|
|
|
3199 trying to debug why particular instantiators are not being processed.
|
|
|
3200
|
|
428
|
3201 The returned value is dependent on the type of specifier. For example,
|
|
|
3202 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
3203 value will be a font-instance object. For glyphs, the returned value
|
|
2953
|
3204 will be an image-instance object.

3238 The definition of "match", and allowed values for MATCHSPEC, are

3239 dependent on the particular type of specifier. Here are some examples:
|

|
3240
|
|
|
3241 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
3242 character, and the specification (a chartable) must give a value for
|
|
|
3243 that character in order to be considered. This allows you to specify,
|
|
|
3244 e.g., a buffer-local display table that only gives values for particular
|
|
|
3245 characters. All other characters are handled as if the buffer-local
|
|
|
3246 display table is not there. (Chartable specifiers are not yet
|
|
|
3247 implemented.)
|
|
|
3248
|
|
3674
|
3249 -- For font specifiers, MATCHSPEC should be a cons (CHARSET . STAGE).
|
|
|
3250 The defined stages are currently `initial' and `final'. On X11, 'initial
|
|
|
3251 is used when the font matching process is looking for fonts that match
|
|
|
3252 the desired registries of the charset--see the `charset-registries'
|
|
|
3253 function. If that match process fails, then the 'final stage comes into
|
|
|
3254 play; this means that a more general lookup is desired, and that a font
|
|
|
3255 doesn't necessarily have to match the desired XLFD for the face, just the
|
|
|
3256 charset repertoire for this charset. It also means that the charset
|
|
|
3257 registry and encoding used will be `iso10646-1', and the characters will

3258 be converted to display using that registry.

3262 such a tag to `set-face-font' in order to set a face's font for that
