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.

551 Return a new specifier object of type TYPE.

552
|
|
|
553 A specifier is an object that can be used to keep track of a property
|
|
|
554 whose value can be per-buffer, per-window, per-frame, or per-device,
|
|
442
|
555 and can further be restricted to a particular console-type or
|
|
|
556 device-class. Specifiers are used, for example, for the various
|
|
|
557 built-in properties of a face; this allows a face to have different
|
|
|
558 values in different frames, buffers, etc.
|
|
|
559
|
|
|
560 When speaking of the value of a specifier, it is important to
|
|
|
561 distinguish between the *setting* of a specifier, called an
|
|
|
562 \"instantiator\", and the *actual value*, called an \"instance\". You
|
|
|
563 put various possible instantiators (i.e. settings) into a specifier
|
|
|
564 and associate them with particular locales (buffer, window, frame,
|
|
|
565 device, global), and then the instance (i.e. actual value) is
|
|
|
566 retrieved in a specific domain (window, frame, device) by looking
|
|
|
567 through the possible instantiators (i.e. settings). This process is
|
|
|
568 called \"instantiation\".
|
|
444
|
569
|
|
442
|
570 To put settings into a specifier, use `set-specifier', or the
|
|
|
571 lower-level functions `add-spec-to-specifier' and
|
|
|
572 `add-spec-list-to-specifier'. You can also temporarily bind a setting
|
|
|
573 to a specifier using `let-specifier'. To retrieve settings, use
|
|
|
574 `specifier-specs', or its lower-level counterpart
|
|
|
575 `specifier-spec-list'. To determine the actual value, use
|
|
|
576 `specifier-instance'.
|
|
|
577
|
|
|
578 For more information, see `set-specifier', `specifier-instance',
|
|
428
|
579 `specifier-specs', and `add-spec-to-specifier'; or, for a detailed
|
|
442
|
580 description of specifiers, including how exactly the instantiation
|
|
|
581 process works, see the chapter on specifiers in the XEmacs Lisp
|
|
|
582 Reference Manual.
|
|
428
|
583
|
|

584 TYPE specifies the particular type of specifier, and should be one of
|
|
442
|
585 the symbols 'generic, 'integer, 'natnum, 'boolean, 'color, 'font,

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

809 A specifier tag set is an entity that is attached to an instantiator
|
|
|
810 and can be used to restrict the scope of that instantiator to a
|
|
|
811 particular device class or device type and/or to mark instantiators
|
|
|
812 added by a particular package so that they can be later removed.
|
|
|
813
|
|
|
814 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
815 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
816 \(The valid device types and device classes are always tags, as are
|
|
|
817 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
|
818 \(as opposed to a list) because the order of the tags or the number of
|
|
|
819 times a particular tag occurs does not matter.
|
|
|
820
|
|
|
821 Each tag has a predicate associated with it, which specifies whether
|
|
|
822 that tag applies to a particular device. The tags which are device types
|
|
|
823 and classes match devices of that type or class. User-defined tags can
|
|
|
824 have any predicate, or none (meaning that all devices match). When
|
|
|
825 attempting to instance a specifier, a particular instantiator is only
|
|
|
826 considered if the device of the domain being instanced over matches
|
|
|
827 all tags in the tag set attached to that instantiator.
|
|
|
828
|
|
|
829 Most of the time, a tag set is not specified, and the instantiator
|
|
|
830 gets a null tag set, which matches all devices.

2684 specifications for more general locales. Any particular specification
|
|
|
2685 that is found may be rejected because its tag set does not match the
|
|
|
2686 device being instantiated over, or because the specification is not
|
|
|
2687 valid for the device of the given domain (e.g. the font or color name

2688 does not exist for this particular X server).

|
2690 NOTE: When errors occur in the process of trying a particular instantiator,
|
|
|
2691 and the instantiator is thus skipped, warnings will be issued at level
|
|
|
2692 `debug'. Normally, such warnings are ignored entirely, but you can change
|
|
|
2693 this by setting `log-warning-minimum-level'. This is useful if you're
|
|
|
2694 trying to debug why particular instantiators are not being processed.
|
|
|
2695
|
|
428
|
2696 The returned value is dependent on the type of specifier. For example,
|
|
|
2697 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2698 value will be a font-instance object. For glyphs, the returned value
|
|
|
2699 will be a string, pixmap, or subwindow.

2719 This function is identical to `specifier-instance' except that a
|

2720 specification will only be considered if it matches MATCHSPEC.
|
|
|
2721 The definition of "match", and allowed values for MATCHSPEC, are
|
|
|
2722 dependent on the particular type of specifier. Here are some examples:
|
|
|
2723
|
|
|
2724 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2725 character, and the specification (a chartable) must give a value for
|
|
|
2726 that character in order to be considered. This allows you to specify,
|
|
|
2727 e.g., a buffer-local display table that only gives values for particular
|
|
|
2728 characters. All other characters are handled as if the buffer-local
|
|
|
2729 display table is not there. (Chartable specifiers are not yet
|
|
|
2730 implemented.)
|
|
|
2731
|
|
872
|
2732 -- For font specifiers, MATCHSPEC should be a list (CHARSET . SECOND-STAGE-P),
|
|
|
2733 and the specification (a font string) must have a registry that matches
|
|
|
2734 the charset's registry. (This only makes sense with Mule support.) This
|
|
|
2735 makes it easy to choose a font that can display a particular
|
|
|
2736 character. (This is what redisplay does, in fact.) SECOND-STAGE-P means
|
|
|
2737 to ignore the font's registry and instead look at the characters in the
|
|
|
2738 font to see if the font can support the charset. This currently only makes
|
|
|
2739 sense under MS Windows.
