annotate lisp/autoload.el @ 4502:8748a3f7ceb4
Handle varalias chains, custom variables in #'user-variable-p.
src/ChangeLog addition:
2008-08-23 Aidan Kehoe <kehoea@parhasard.net>
* eval.c (Fuser_variable_p): Moved to symbols.c
* symbols.c (Fcustom_variable_p): Moved here from custom.el.
(user_variable_alias_check_fun): Mapper function used in
`user-variable-p'.
(Fuser_variable_p): Moved here from eval.c, to allow it to examine
the variable alias chain. Expanded to check each entry in the
variable alias chain for signs of being a user variable;
documentation updated, noting the differences between GNU's
behaviour and ours (ours is a little more sensible)
(map_varalias_chain): New.
Given a C function, call it at least once for each symbol in a
symbol's varalias chain, signalling an error if there's a cycle,
and returning immediately if the function returns something other
than Qzero.
(Fdefvaralias): Correct the use of the word "alias" in the
docstring and in the argument name. Motivate this in a
comment. Add support for a DOCSTRING argument, something GNU has
too, and document this
* gc.c (vars_of_gc): Start the docstring of
`garbage-collection-messages' with an asterisk, to indicate that
it's a user variable.
lisp/ChangeLog addition:
2008-08-23 Aidan Kehoe <kehoea@parhasard.net>
* custom.el: Move #'custom-variable-p to C, since it's now called
from #'user-variable-p.

| 30 ;;; syncable. | |
| 428 | 31 |
| 32 ;;; Commentary: | |
| 33 | |
| 1232 | 34 ;; This code keeps auto-autoloads.el files up to date. It interprets |
| 35 ;; magic cookies (of the form ";;;###autoload" in Lisp source files | |
| 36 ;; and "/* ###autoload */" in C source files) in various useful ways. | |
| 2548 | 37 ;; It is also used to maintain custom-defines.el files, since most of |
| 38 ;; the logic for computing them is the same as for auto-autoloads.el. | |
| 1232 | 39 |
| 40 ;; Usage | |
| 41 ;; ===== | |
| 42 | |
| 43 ;; Recommended usage for this library, as implemented in the core | |
| 44 ;; build process, is | |
| 45 | |
| 46 ;; xemacs -no-packages -batch \ | |
| 2548 | 47 ;; -l autoload -f batch-update-directory-autoloads PREFIX DIRECTORY |
| 1232 | 48 |
| 49 ;; which causes XEmacs to update the file named by PATH from the .el | |
| 50 ;; files in DIRECTORY (but not recursing into subdirectories) and (if | |
| 51 ;; the autoload file is not already protected with a feature test) add | |
| 52 ;; a check and provide for 'PREFIX-autoloads. Currently there is no | |
| 53 ;; sanity check for the provided feature; it is recommended that you | |
| 54 ;; nuke any existing auto-autoloads.el before running the command. | |
| 55 | |
| 56 ;; There is not yet a recommended API for updating multiple directories | |
| 57 ;; into a single auto-autoloads file. Using the recipe above for each | |
| 58 ;; DIRECTORY with the same PATH should work but has not been tested. | |
| 59 ;; There is no API for recursing into subdirectories. There probably | |
| 60 ;; won't be; given the wide variety of ways that existing Lisp packages | |
| 61 ;; arrange their files, and the fact that source packages and installed | |
| 62 ;; packages have a somewhat different directory structure, this seems far | |
| 63 ;; too risky. Use a script or a Lisp library with an explicit list of | |
| 64 ;; PATHs; see update-elc.el for how to do this without recursive invocation | |
| 65 ;; of XEmacs). | |
| 66 | |
| 67 ;; The probable next step is to fix up the packages to use the | |
| 2548 | 68 ;; `batch-update-directory-autoloads' API. However, for backward |
| 1232 | 69 ;; compatibility with XEmacs 21.4 and 21.1, this can't be done quickly. |
| 70 | |
| 71 ;; For backward compatibility the API used in the packages/XEmacs.rules: | |
| 72 | |
| 73 ;; xemacs -vanilla -batch -eval "$(AUTOLOAD_PACKAGE_NAME)" \ | |
| 2548 | 74 ;; -l autoload -f batch-update-autoloads $(AUTOLOAD_PATH) |
| 1232 | 75 |
| 76 ;; is supported, and the implementation is unchanged. However, | |
| 77 ;; revision of the API (in a backward compatible way) and the | |
| 78 ;; implementation are planned, and until those stabilize it is too | |
| 79 ;; risky to use this version of XEmacs for package releases. | |
| 80 | |
| 81 ;; Implementation: | |
| 82 ;; =============== | |
| 83 | |
| 84 ;; #### This section should be moved to the Internals manual, or | |
| 85 ;; (maybe) the Lispref, and integrated with the information above. | |
| 86 ;; Don't believe anything written here; the code is still a mess, and | |
| 87 ;; this is a lot of guesswork. | |
| 88 | |
| 89 ;; Autoloads are used in a number of contexts, including core Lisp, | |
| 90 ;; packaged Lisp, and ELLs (dynamically loadable compiled objects | |
| 91 ;; providing Lisp functionality). There two general strategies for | |
| 92 ;; collecting autoloads. The first is to put autoloads for a package | |
| 93 ;; in a package-specific auto-autoloads file. This is easy to | |
| 94 ;; implement, and allows packages to be distributed with prebuilt | |
| 95 ;; auto-autoloads files. The second is to collect all the autoloads | |
| 96 ;; in a single global auto-autoloads file. This is alleged to speed | |
| 97 ;; up initialization significantly, but requires care to ensure that | |
| 98 ;; auto-autoloads files remain synchronized with the libraries. | |
| 99 | |
| 100 ;; The traditional logic for determining where to put autoload | |
| 101 ;; definitions is complex and is now deprecated. The special variable | |
| 102 ;; `generated-autoload-file' is used to hold the path to the file, and | |
| 103 ;; is initialized to the traditional (well, it's a new tradition with | |
| 104 ;; XEmacs 20) $blddir/lisp/auto-autoloads.el. However, this variable | |
| 105 ;; may be bound by calling code, or may be generated at collect time | |
| 106 ;; and I'm not even sure the initialized value was ever used any more. | |
| 107 | |
| 108 ;; Because there may be multiple auto-autoloads files in use (in XEmacs | |
| 109 ;; 21.x with a full complement of packages there are dozens), and they may | |
| 110 ;; contain initializations that would be dangerous to reexecute, each is | |
| 111 ;; protected by a feature test. By convention, the feature symbol is of | |
| 112 ;; the form "NAME-autoloads". For packages, the special variable | |
| 113 ;; `autoload-package-name' is used to determine NAME. In the core, | |
| 114 ;; autoloads are defined in the modules (all of which are collected in a | |
| 115 ;; single auto-autoloads file), using NAME=modules, in the lisp directory | |
| 116 ;; using NAME=lisp, and in the lisp/mule directory, using NAME=mule, for | |
| 117 ;; the autoloads feature. These latter are computed by the autoloads | |
| 118 ;; function at collect time. | |
