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.

535 Return a new specifier object of type TYPE.

536
|
|
|
537 A specifier is an object that can be used to keep track of a property
|
|
|
538 whose value can be per-buffer, per-window, per-frame, or per-device,
|
|
442
|
539 and can further be restricted to a particular console-type or
|
|
|
540 device-class. Specifiers are used, for example, for the various
|
|
|
541 built-in properties of a face; this allows a face to have different
|
|
|
542 values in different frames, buffers, etc.
|
|
|
543
|
|
|
544 When speaking of the value of a specifier, it is important to
|
|
|
545 distinguish between the *setting* of a specifier, called an
|
|
|
546 \"instantiator\", and the *actual value*, called an \"instance\". You
|
|
|
547 put various possible instantiators (i.e. settings) into a specifier
|
|
|
548 and associate them with particular locales (buffer, window, frame,
|
|
|
549 device, global), and then the instance (i.e. actual value) is
|
|
|
550 retrieved in a specific domain (window, frame, device) by looking
|
|
|
551 through the possible instantiators (i.e. settings). This process is
|
|
|
552 called \"instantiation\".
|
|
444
|
553
|
|
442
|
554 To put settings into a specifier, use `set-specifier', or the
|
|
|
555 lower-level functions `add-spec-to-specifier' and
|
|
|
556 `add-spec-list-to-specifier'. You can also temporarily bind a setting
|
|
|
557 to a specifier using `let-specifier'. To retrieve settings, use
|
|
|
558 `specifier-specs', or its lower-level counterpart
|
|
|
559 `specifier-spec-list'. To determine the actual value, use
|
|
|
560 `specifier-instance'.
|
|
|
561
|
|
|
562 For more information, see `set-specifier', `specifier-instance',
|
|
428
|
563 `specifier-specs', and `add-spec-to-specifier'; or, for a detailed
|
|
442
|
564 description of specifiers, including how exactly the instantiation
|
|
|
565 process works, see the chapter on specifiers in the XEmacs Lisp
|
|
|
566 Reference Manual.
|
|
428
|
567
|
|
|
568 TYPE specifies the particular type of specifier, and should be one of
|
|
442
|
569 the symbols 'generic, 'integer, 'natnum, 'boolean, 'color, 'font,
|
|

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

793 A specifier tag set is an entity that is attached to an instantiator
|
|
|
794 and can be used to restrict the scope of that instantiator to a
|
|
|
795 particular device class or device type and/or to mark instantiators
|
|
|
796 added by a particular package so that they can be later removed.
|
|
|
797
|
|
|
798 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
799 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
800 \(The valid device types and device classes are always tags, as are
|
|
|
801 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
|
802 \(as opposed to a list) because the order of the tags or the number of
|
|
|
803 times a particular tag occurs does not matter.
|
|
|
804
|
|
|
805 Each tag has a predicate associated with it, which specifies whether
|
|
|
806 that tag applies to a particular device. The tags which are device types
|
|
|
807 and classes match devices of that type or class. User-defined tags can
|
|
|
808 have any predicate, or none (meaning that all devices match). When
|
|
|
809 attempting to instance a specifier, a particular instantiator is only
|
|
|
810 considered if the device of the domain being instanced over matches
|
|
|
811 all tags in the tag set attached to that instantiator.
|
|
|
812
|
|
|
813 Most of the time, a tag set is not specified, and the instantiator
|
|
|
814 gets a null tag set, which matches all devices.

2652 "Instantiating" a specifier in a particular domain means determining

2653 the specifier's "value" in that domain. This is accomplished by

2654 searching through the specifications in the specifier that correspond
|
|
|
2655 to all locales that can be derived from the given domain, from specific
|
|
|
2656 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2657 specifications are searched for as follows:
|
|
|
2658
|
|
|
2659 1. A specification whose locale is the window itself;
|
|
|
2660 2. A specification whose locale is the window's buffer;
|
|
|
2661 3. A specification whose locale is the window's frame;
|
|
|
2662 4. A specification whose locale is the window's frame's device;
|
|
|
2663 5. A specification whose locale is 'global.
|
|
|
2664
|
|
|
2665 If all of those fail, then the C-code-provided fallback value for
|
|
|
2666 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2667 an inst-list, then this function attempts to instantiate that list
|
|
|
2668 just as when a specification is located in the first five steps above.
|
|
|
2669 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2670 recursively on this specifier and the return value used. Note,
|
|
|
2671 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2672 the fallback value will not be consulted.
|
|
|
2673
|
|
|
2674 Note that there may be more than one specification matching a particular
|
|
|
2675 locale; all such specifications are considered before looking for any
|
|
|
2676 specifications for more general locales. Any particular specification
|
|
|
2677 that is found may be rejected because its tag set does not match the
|
|
|
2678 device being instantiated over, or because the specification is not
|
|
|
2679 valid for the device of the given domain (e.g. the font or color name
|
|
|
2680 does not exist for this particular X server).
|
|
|
2681
|
|
793
|
2682 NOTE: When errors occur in the process of trying a particular instantiator,
|
|
|
2683 and the instantiator is thus skipped, warnings will be issued at level
|
|
|
2684 `debug'. Normally, such warnings are ignored entirely, but you can change
|
|
|
2685 this by setting `log-warning-minimum-level'. This is useful if you're
|
|
|
2686 trying to debug why particular instantiators are not being processed.
|
|
|
2687
|
|
428
|
2688 The returned value is dependent on the type of specifier. For example,
|
|
|

2711 This function is identical to `specifier-instance' except that a
|
|
|
2712 specification will only be considered if it matches MATCHSPEC.
|
|
|
2713 The definition of "match", and allowed values for MATCHSPEC, are
|
|
|
2714 dependent on the particular type of specifier. Here are some examples:
|
|
|
2715
|
|
|
2716 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2717 character, and the specification (a chartable) must give a value for
|
|
|
2718 that character in order to be considered. This allows you to specify,
|
|
|
2719 e.g., a buffer-local display table that only gives values for particular
|
|
|
2720 characters. All other characters are handled as if the buffer-local
|
|
|
2721 display table is not there. (Chartable specifiers are not yet
|
|
|
2722 implemented.)
|
|
|
2723
|
|
872
|
2724 -- For font specifiers, MATCHSPEC should be a list (CHARSET . SECOND-STAGE-P),
|
|
|
2725 and the specification (a font string) must have a registry that matches
|
|
|
2726 the charset's registry. (This only makes sense with Mule support.) This
|
|
|
2727 makes it easy to choose a font that can display a particular
|
|
|
2728 character. (This is what redisplay does, in fact.) SECOND-STAGE-P means
|
|
|
2729 to ignore the font's registry and instead look at the characters in the
|
|
|
2730 font to see if the font can support the charset. This currently only makes
|
|
|
2731 sense under MS Windows.

2835 set_specifier_fallback(), followed (optionally) by

2837 - If you used set_specifier_caching(), make sure to create the
