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

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

208 objects are always held permanently in special lists, and deleted
|
|

209 objects are never on these lists and never reusable). To handle
|
|
|
210 this, we just have cleanup_specifiers() called periodically

211 (at the beginning of garbage collection); it removes all dead
|
|
|
212 objects.
|

213

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

218 We now use weak lists for this purpose.

666 A specifier tag set is an entity that is attached to an instantiator
|
|
|
667 and can be used to restrict the scope of that instantiator to a
|
|
|
668 particular device class or device type and/or to mark instantiators
|

|
669 added by a particular package so that they can be later removed.
|
|
|
670
|
|
|
671 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
672 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
|
673 (The valid device types and device classes are always tags, as are
|
|
|
674 any tags defined by `define-specifier-tag'.) It is called a \"tag set\"
|
|
|
675 (as opposed to a list) because the order of the tags or the number of
|
|
|
676 times a particular tag occurs does not matter.
|
|
|
677
|
|
|
678 Each tag has a predicate associated with it, which specifies whether
|
|
|
679 that tag applies to a particular device. The tags which are device types
|
|
|
680 and classes match devices of that type or class. User-defined tags can
|
|
|
681 have any predicate, or none (meaning that all devices match). When
|
|
|
682 attempting to instance a specifier, a particular instantiator is only
|
|
|
683 considered if the device of the domain being instanced over matches
|
|
|
684 all tags in the tag set attached to that instantiator.
|
|
|
685
|
|
|
686 Most of the time, a tag set is not specified, and the instantiator
|
|
|
687 gets a null tag set, which matches all devices.

2430 DOMAIN should be a window, frame, or device. Other values that are legal
|
|

2431 as a locale (e.g. a buffer) are not valid as a domain because they do not
|
|
|
2432 provide enough information to identify a particular device (see
|
|
|
2433 `valid-specifier-domain-p'). DOMAIN defaults to the selected window
|
|
|
2434 if omitted.
|
|
|
2435
|
|
|
2436 \"Instantiating\" a specifier in a particular domain means determining
|
|
|
2437 the specifier's \"value\" in that domain. This is accomplished by
|
|
|
2438 searching through the specifications in the specifier that correspond
|
|
|
2439 to all locales that can be derived from the given domain, from specific
|
|
|
2440 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2441 specifications are searched for as follows:
|
|
|
2442
|
|
|
2443 1. A specification whose locale is the window's buffer;
|
|
|
2444 2. A specification whose locale is the window itself;
|
|
|
2445 3. A specification whose locale is the window's frame;
|
|
|
2446 4. A specification whose locale is the window's frame's device;
|
|
|
2447 5. A specification whose locale is 'global.
|
|
|
2448
|
|
|
2449 If all of those fail, then the C-code-provided fallback value for
|
|
|
2450 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2451 an inst-list, then this function attempts to instantiate that list
|
|
|
2452 just as when a specification is located in the first five steps above.
|
|
|
2453 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2454 recursively on this specifier and the return value used. Note,
|
|
|
2455 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2456 the fallback value will not be consulted.
|
|
|
2457
|
|
|
2458 Note that there may be more than one specification matching a particular
|
|
|
2459 locale; all such specifications are considered before looking for any
|
|
|
2460 specifications for more general locales. Any particular specification
|
|
|
2461 that is found may be rejected because its tag set does not match the
|
|
|
2462 device being instantiated over, or because the specification is not
|
|
|
2463 valid for the device of the given domain (e.g. the font or color name
|
|
|
2464 does not exist for this particular X server).
|
|
|
2465
|
|
|
2466 The returned value is dependent on the type of specifier. For example,
|
|
|
2467 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2468 value will be a font-instance object. For glyphs, the returned value
|
|
|
2469 will be a string, pixmap, or subwindow.

2491 This function is identical to `specifier-instance' except that a
|
|
|
2492 specification will only be considered if it matches MATCHSPEC.
|
|
|
2493 The definition of \"match\", and allowed values for MATCHSPEC, are
|
|
|
2494 dependent on the particular type of specifier. Here are some examples:
|
|
|
2495
|
|
|
2496 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2497 character, and the specification (a chartable) must give a value for
|
|
|
2498 that character in order to be considered. This allows you to specify,
|
|
|
2499 e.g., a buffer-local display table that only gives values for particular
|
|
|
2500 characters. All other characters are handled as if the buffer-local
|
|
|
2501 display table is not there. (Chartable specifiers are not yet
|
|
|
2502 implemented.)
|
|
|
2503
|
|
|
2504 -- For font specifiers, MATCHSPEC should be a charset, and the specification
|
|
|
2505 (a font string) must have a registry that matches the charset's registry.
|
|
|
2506 (This only makes sense with Mule support.) This makes it easy to choose a
|
|
|
2507 font that can display a particular character. (This is what redisplay
|
|
|
2508 does, in fact.)
