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

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

225 objects are always held permanently in special lists, and deleted
|
|
|
226 objects are never on these lists and never reusable). To handle
|
|
|
227 this, we just have cleanup_specifiers() called periodically

228 (at the beginning of garbage collection); it removes all dead
|

229 objects.
|

230
|

|
231 For windows, however, it's trickier because dead objects can be
|
|
|
232 converted to live ones again if the dead object is in a window
|
|
|
233 configuration. Therefore, for windows, "no longer in use"
|
|
|
234 corresponds to when the window object is garbage-collected.
|
|

235 We now use weak lists for this purpose.

|
|
|
533 A specifier is an object that can be used to keep track of a property
|
|
|
534 whose value can be per-buffer, per-window, per-frame, or per-device,
|
|
408
|
535 and can further be restricted to a particular console-type or
|
|
|
536 device-class. Specifiers are used, for example, for the various
|
|
|
537 built-in properties of a face; this allows a face to have different
|
|
|
538 values in different frames, buffers, etc.
|
|
|
539
|
|
|
540 When speaking of the value of a specifier, it is important to
|
|
|
541 distinguish between the *setting* of a specifier, called an
|
|
|
542 \"instantiator\", and the *actual value*, called an \"instance\". You
|
|
|
543 put various possible instantiators (i.e. settings) into a specifier
|
|
|
544 and associate them with particular locales (buffer, window, frame,
|
|
|
545 device, global), and then the instance (i.e. actual value) is
|
|
|
546 retrieved in a specific domain (window, frame, device) by looking
|
|
|
547 through the possible instantiators (i.e. settings). This process is
|
|
|
548 called \"instantiation\".
|
|
|
549
|
|
|
550 To put settings into a specifier, use `set-specifier', or the
|
|
|
551 lower-level functions `add-spec-to-specifier' and
|
|
|
552 `add-spec-list-to-specifier'. You can also temporarily bind a setting
|
|
|
553 to a specifier using `let-specifier'. To retrieve settings, use
|
|
|
554 `specifier-specs', or its lower-level counterpart
|
|
|
555 `specifier-spec-list'. To determine the actual value, use
|
|
|
556 `specifier-instance'.
|
|
|
557
|
|
|
558 For more information, see `set-specifier', `specifier-instance',
|
|
0
|
559 `specifier-specs', and `add-spec-to-specifier'; or, for a detailed
|
|
408
|
560 description of specifiers, including how exactly the instantiation
|
|
|
561 process works, see the chapter on specifiers in the XEmacs Lisp
|
|
|
562 Reference Manual.

0
|
563

|

408
|
565 the symbols 'generic, 'integer, 'natnum, 'boolean, 'color, 'font,

566 'image, 'face-boolean, 'display-table, 'gutter, 'gutter-size,

785 A specifier tag set is an entity that is attached to an instantiator
|
|
|
786 and can be used to restrict the scope of that instantiator to a
|
|
|
787 particular device class or device type and/or to mark instantiators
|
|
|
788 added by a particular package so that they can be later removed.
|
|
|
789
|
|
|
790 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
791 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
272
|
792 \(The valid device types and device classes are always tags, as are
|
|
185
|
793 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
272
|
794 \(as opposed to a list) because the order of the tags or the number of
|
|
0
|
795 times a particular tag occurs does not matter.
|
|
|
796
|
|
|
797 Each tag has a predicate associated with it, which specifies whether
|
|
|
798 that tag applies to a particular device. The tags which are device types
|
|
|
799 and classes match devices of that type or class. User-defined tags can
|
|
|
800 have any predicate, or none (meaning that all devices match). When
|
|
|
801 attempting to instance a specifier, a particular instantiator is only
|
|
|
802 considered if the device of the domain being instanced over matches
|
|
|
803 all tags in the tag set attached to that instantiator.
|
|
|
804
|
|
|
805 Most of the time, a tag set is not specified, and the instantiator
|
|
|
806 gets a null tag set, which matches all devices.

|
2647 "Instantiating" a specifier in a particular domain means determining
|
|
|
2648 the specifier's "value" in that domain. This is accomplished by
|
|
0
|
2649 searching through the specifications in the specifier that correspond
|
|
|
2650 to all locales that can be derived from the given domain, from specific
|
|
|
2651 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2652 specifications are searched for as follows:
|
|
|
2653
|
|
284
|
2654 1. A specification whose locale is the window itself;
|
|
|
2655 2. A specification whose locale is the window's buffer;
|
|
0
|
2656 3. A specification whose locale is the window's frame;
|
|
|
2657 4. A specification whose locale is the window's frame's device;
|
|
|
2658 5. A specification whose locale is 'global.
|
|
|
2659
|
|
|
2660 If all of those fail, then the C-code-provided fallback value for
|
|
|
2661 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2662 an inst-list, then this function attempts to instantiate that list
|
|
|
2663 just as when a specification is located in the first five steps above.
|
|
|
2664 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2665 recursively on this specifier and the return value used. Note,
|
|
|
2666 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2667 the fallback value will not be consulted.
|
|
|
2668
|
|
|
2669 Note that there may be more than one specification matching a particular
|
|
|
2670 locale; all such specifications are considered before looking for any
|
|
|
2671 specifications for more general locales. Any particular specification
|
|
|
2672 that is found may be rejected because its tag set does not match the
|
|
|
2673 device being instantiated over, or because the specification is not
|
|
|
2674 valid for the device of the given domain (e.g. the font or color name
|
|
|
2675 does not exist for this particular X server).
|
|
|
2676
|
|
|
2677 The returned value is dependent on the type of specifier. For example,
|
|
|
2678 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2679 value will be a font-instance object. For glyphs, the returned value
|
|
|
2680 will be a string, pixmap, or subwindow.
|
|
|
2681

|
|
2682 See also `specifier-matching-instance'.

2700 This function is identical to `specifier-instance' except that a

|
|
185
|
2702 The definition of "match", and allowed values for MATCHSPEC, are
|
|
0
|
2703 dependent on the particular type of specifier. Here are some examples:
|
|
|
2704
|
|
|
2705 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2706 character, and the specification (a chartable) must give a value for
|
|
|
2707 that character in order to be considered. This allows you to specify,
|
|
|
2708 e.g., a buffer-local display table that only gives values for particular
|
|
|
2709 characters. All other characters are handled as if the buffer-local
|
|
|
2710 display table is not there. (Chartable specifiers are not yet
|
|
|
2711 implemented.)
|
|
|
2712
|
|
|
2713 -- For font specifiers, MATCHSPEC should be a charset, and the specification
|
|
|
2714 (a font string) must have a registry that matches the charset's registry.
|
|
|
2715 (This only makes sense with Mule support.) This makes it easy to choose a
|
|
|
2716 font that can display a particular character. (This is what redisplay
|
|
|
2717 does, in fact.)
