| 2548 | 26 ;;; Synched up with: FSF 21.2 by Ben Wing. |
| 27 ;;; Note that update-file-autoloads is seriously modified and not really | |
| 28 ;;; syncable. | |
| 428 | 29 |
| 30 ;;; Commentary: | |
| 31 | |
| 1232 | 32 ;; This code keeps auto-autoloads.el files up to date. It interprets |
| 33 ;; magic cookies (of the form ";;;###autoload" in Lisp source files | |
| 34 ;; and "/* ###autoload */" in C source files) in various useful ways. | |
| 2548 | 35 ;; It is also used to maintain custom-defines.el files, since most of |
| 36 ;; the logic for computing them is the same as for auto-autoloads.el. | |
| 1232 | 37 |
| 38 ;; Usage | |
| 39 ;; ===== | |
| 40 | |
| 41 ;; Recommended usage for this library, as implemented in the core | |
| 42 ;; build process, is | |
| 43 | |
| 44 ;; xemacs -no-packages -batch \ | |
| 2548 | 45 ;; -l autoload -f batch-update-directory-autoloads PREFIX DIRECTORY |
| 1232 | 46 |
| 47 ;; which causes XEmacs to update the file named by PATH from the .el | |
| 48 ;; files in DIRECTORY (but not recursing into subdirectories) and (if | |
| 49 ;; the autoload file is not already protected with a feature test) add | |
| 50 ;; a check and provide for 'PREFIX-autoloads. Currently there is no | |
| 51 ;; sanity check for the provided feature; it is recommended that you | |
| 52 ;; nuke any existing auto-autoloads.el before running the command. | |
| 53 | |
| 54 ;; There is not yet a recommended API for updating multiple directories | |
| 55 ;; into a single auto-autoloads file. Using the recipe above for each | |
| 56 ;; DIRECTORY with the same PATH should work but has not been tested. | |
| 57 ;; There is no API for recursing into subdirectories. There probably | |
| 58 ;; won't be; given the wide variety of ways that existing Lisp packages | |
| 59 ;; arrange their files, and the fact that source packages and installed | |
| 60 ;; packages have a somewhat different directory structure, this seems far | |
| 61 ;; too risky. Use a script or a Lisp library with an explicit list of | |
| 62 ;; PATHs; see update-elc.el for how to do this without recursive invocation | |
| 63 ;; of XEmacs). | |
| 64 | |
| 65 ;; The probable next step is to fix up the packages to use the | |
| 2548 | 66 ;; `batch-update-directory-autoloads' API. However, for backward |
| 1232 | 67 ;; compatibility with XEmacs 21.4 and 21.1, this can't be done quickly. |
| 68 | |
| 69 ;; For backward compatibility the API used in the packages/XEmacs.rules: | |
| 70 | |
| 71 ;; xemacs -vanilla -batch -eval "$(AUTOLOAD_PACKAGE_NAME)" \ | |
| 2548 | 72 ;; -l autoload -f batch-update-autoloads $(AUTOLOAD_PATH) |
| 1232 | 73 |
| 74 ;; is supported, and the implementation is unchanged. However, | |
| 75 ;; revision of the API (in a backward compatible way) and the | |
| 76 ;; implementation are planned, and until those stabilize it is too | |
| 77 ;; risky to use this version of XEmacs for package releases. | |
| 78 | |
| 79 ;; Implementation: | |
| 80 ;; =============== | |
| 81 | |
| 82 ;; #### This section should be moved to the Internals manual, or | |
| 83 ;; (maybe) the Lispref, and integrated with the information above. | |
| 84 ;; Don't believe anything written here; the code is still a mess, and | |
| 85 ;; this is a lot of guesswork. | |
| 86 | |
| 87 ;; Autoloads are used in a number of contexts, including core Lisp, | |
| 88 ;; packaged Lisp, and ELLs (dynamically loadable compiled objects | |
| 89 ;; providing Lisp functionality). There two general strategies for | |
| 90 ;; collecting autoloads. The first is to put autoloads for a package | |
| 91 ;; in a package-specific auto-autoloads file. This is easy to | |
| 92 ;; implement, and allows packages to be distributed with prebuilt | |
| 93 ;; auto-autoloads files. The second is to collect all the autoloads | |
| 94 ;; in a single global auto-autoloads file. This is alleged to speed | |
| 95 ;; up initialization significantly, but requires care to ensure that | |
| 96 ;; auto-autoloads files remain synchronized with the libraries. | |
| 97 | |
| 98 ;; The traditional logic for determining where to put autoload | |
| 99 ;; definitions is complex and is now deprecated. The special variable | |
| 100 ;; `generated-autoload-file' is used to hold the path to the file, and | |
| 101 ;; is initialized to the traditional (well, it's a new tradition with | |
| 102 ;; XEmacs 20) $blddir/lisp/auto-autoloads.el. However, this variable | |
| 103 ;; may be bound by calling code, or may be generated at collect time | |
| 104 ;; and I'm not even sure the initialized value was ever used any more. | |
| 105 | |
| 106 ;; Because there may be multiple auto-autoloads files in use (in XEmacs | |
| 107 ;; 21.x with a full complement of packages there are dozens), and they may | |
| 108 ;; contain initializations that would be dangerous to reexecute, each is | |
| 109 ;; protected by a feature test. By convention, the feature symbol is of | |
| 110 ;; the form "NAME-autoloads". For packages, the special variable | |
| 111 ;; `autoload-package-name' is used to determine NAME. In the core, | |
| 112 ;; autoloads are defined in the modules (all of which are collected in a | |
| 113 ;; single auto-autoloads file), using NAME=modules, in the lisp directory | |
| 114 ;; using NAME=lisp, and in the lisp/mule directory, using NAME=mule, for | |
| 115 ;; the autoloads feature. These latter are computed by the autoloads | |
| 116 ;; function at collect time. | |
| 428 | 117 |
