|

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

196 corresponds exactly to when the object is deleted (non-deleted
|

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

200 (at the beginning of garbage collection); it removes all dead
|
|
|
201 objects.
|
|
|
202
|
|
|
203 For windows, however, it's trickier because dead objects can be
|
|
|
204 converted to live ones again if the dead object is in a window
|
|
|
205 configuration. Therefore, for windows, "no longer in use"
|
|
|
206 corresponds to when the window object is garbage-collected.
|
|
|
207 We now use weak lists for this purpose.

642 A specifier tag set is an entity that is attached to an instantiator

644 particular device class or device type and/or to mark instantiators

|
645 added by a particular package so that they can be later removed.
|
|
|
646
|
|
|
647 A specifier tag set consists of a list of zero of more specifier tags,
|
|
|
648 each of which is a symbol that is recognized by XEmacs as a tag.
|
|
272
|
649 \(The valid device types and device classes are always tags, as are
|
|
185
|
650 any tags defined by `define-specifier-tag'.) It is called a "tag set"
|
|
272
|
651 \(as opposed to a list) because the order of the tags or the number of
|
|
0
|
652 times a particular tag occurs does not matter.
|
|
|
653
|
|
|
654 Each tag has a predicate associated with it, which specifies whether
|
|
|
655 that tag applies to a particular device. The tags which are device types
|
|
|
656 and classes match devices of that type or class. User-defined tags can
|
|
|
657 have any predicate, or none (meaning that all devices match). When
|
|
|
658 attempting to instance a specifier, a particular instantiator is only
|
|
|
659 considered if the device of the domain being instanced over matches
|
|
|
660 all tags in the tag set attached to that instantiator.
|
|
|
661
|
|
|
662 Most of the time, a tag set is not specified, and the instantiator
|
|

663 gets a null tag set, which matches all devices.

2417 "Instantiating" a specifier in a particular domain means determining
|
|
|
2418 the specifier's "value" in that domain. This is accomplished by
|
|
0
|
2419 searching through the specifications in the specifier that correspond
|
|
|
2420 to all locales that can be derived from the given domain, from specific
|
|
|
2421 to general. In most cases, the domain is an Emacs window. In that case
|
|
|
2422 specifications are searched for as follows:
|
|
|
2423
|
|
|
2424 1. A specification whose locale is the window's buffer;
|
|
|
2425 2. A specification whose locale is the window itself;
|
|
|
2426 3. A specification whose locale is the window's frame;
|
|
|
2427 4. A specification whose locale is the window's frame's device;
|
|
|
2428 5. A specification whose locale is 'global.
|
|
|
2429
|
|
|
2430 If all of those fail, then the C-code-provided fallback value for
|
|
|
2431 this specifier is consulted (see `specifier-fallback'). If it is
|
|
|
2432 an inst-list, then this function attempts to instantiate that list
|
|
|
2433 just as when a specification is located in the first five steps above.
|
|
|
2434 If the fallback is a specifier, `specifier-instance' is called
|
|
|
2435 recursively on this specifier and the return value used. Note,
|
|
|
2436 however, that if the optional argument NO-FALLBACK is non-nil,
|
|
|
2437 the fallback value will not be consulted.
|
|
|
2438
|
|
|
2439 Note that there may be more than one specification matching a particular
|
|
|
2440 locale; all such specifications are considered before looking for any
|
|
|
2441 specifications for more general locales. Any particular specification
|
|
|
2442 that is found may be rejected because its tag set does not match the
|
|
|
2443 device being instantiated over, or because the specification is not
|
|
|
2444 valid for the device of the given domain (e.g. the font or color name
|
|
|
2445 does not exist for this particular X server).
|
|
|
2446
|
|
|
2447 The returned value is dependent on the type of specifier. For example,
|
|
|
2448 for a font specifier (as returned by the `face-font' function), the returned
|
|
|
2449 value will be a font-instance object. For glyphs, the returned value
|
|
|
2450 will be a string, pixmap, or subwindow.
|
|

185

2472 The definition of "match", and allowed values for MATCHSPEC, are

2473 dependent on the particular type of specifier. Here are some examples:

|
|
2474
|
|
|
2475 -- For chartable (e.g. display table) specifiers, MATCHSPEC should be a
|
|
|
2476 character, and the specification (a chartable) must give a value for
|
|
|
2477 that character in order to be considered. This allows you to specify,
|
|
|
2478 e.g., a buffer-local display table that only gives values for particular
|
|
|
2479 characters. All other characters are handled as if the buffer-local
|
|
|
2480 display table is not there. (Chartable specifiers are not yet
|
|
|
2481 implemented.)
|
|
|
2482
|
|
|
2483 -- For font specifiers, MATCHSPEC should be a charset, and the specification
|
|
|
2484 (a font string) must have a registry that matches the charset's registry.
|
|
|
2485 (This only makes sense with Mule support.) This makes it easy to choose a
|
|
|
2486 font that can display a particular character. (This is what redisplay
|
|
|
2487 does, in fact.)
