35 | ;;; Commentary: | |
36 | ||
37 | ;; The idea behind package.el is to be able to download packages and | |
38 | ;; install them. Packages are versioned and have versioned | |
39 | ;; dependencies. Furthermore, this supports built-in packages which | |
40 | ;; may or may not be newer than user-specified packages. This makes | |
41 | ;; it possible to upgrade Emacs and automatically disable packages | |
42 | ;; which have moved from external to core. (Note though that we don't | |
43 | ;; currently register any of these, so this feature does not actually | |
44 | ;; work.) | |
45 | ||
44198b6e CY |
46 | ;; A package is described by its name and version. The distribution |
47 | ;; format is either a tar file or a single .el file. | |
48 | ||
49 | ;; A tar file should be named "NAME-VERSION.tar". The tar file must | |
50 | ;; unpack into a directory named after the package and version: | |
51 | ;; "NAME-VERSION". It must contain a file named "PACKAGE-pkg.el" | |
52 | ;; which consists of a call to define-package. It may also contain a | |
53 | ;; "dir" file and the info files it references. | |
54 | ||
bc44bef7 | 55 | ;; A .el file is named "NAME-VERSION.el" in the remote archive, but is |
44198b6e CY |
56 | ;; installed as simply "NAME.el" in a directory named "NAME-VERSION". |
57 | ||
bc44bef7 PH |
58 | ;; The downloader downloads all dependent packages. By default, |
59 | ;; packages come from the official GNU sources, but others may be | |
60 | ;; added by customizing the `package-archives' alist. Packages get | |
61 | ;; byte-compiled at install time. | |
44198b6e CY |
62 | |
63 | ;; At activation time we will set up the load-path and the info path, | |
64 | ;; and we will load the package's autoloads. If a package's | |
65 | ;; dependencies are not available, we will not activate that package. | |
66 | ||
67 | ;; Conceptually a package has multiple state transitions: | |
68 | ;; | |
69 | ;; * Download. Fetching the package from ELPA. | |
70 | ;; * Install. Untar the package, or write the .el file, into | |
71 | ;; ~/.emacs.d/elpa/ directory. | |
72 | ;; * Byte compile. Currently this phase is done during install, | |
73 | ;; but we may change this. | |
74 | ;; * Activate. Evaluate the autoloads for the package to make it | |
75 | ;; available to the user. | |
76 | ;; * Load. Actually load the package and run some code from it. | |
77 | ||
78 | ;; Other external functions you may want to use: | |
79 | ;; | |
015eea59 | 80 | ;; M-x list-packages |
44198b6e CY |
81 | ;; Enters a mode similar to buffer-menu which lets you manage |
82 | ;; packages. You can choose packages for install (mark with "i", | |
83 | ;; then "x" to execute) or deletion (not implemented yet), and you | |
84 | ;; can see what packages are available. This will automatically | |
85 | ;; fetch the latest list of packages from ELPA. | |
86 | ;; | |
87 | ;; M-x package-list-packages-no-fetch | |
88 | ;; Like package-list-packages, but does not automatically fetch the | |
89 | ;; new list of packages. | |
90 | ;; | |
91 | ;; M-x package-install-from-buffer | |
92 | ;; Install a package consisting of a single .el file that appears | |
93 | ;; in the current buffer. This only works for packages which | |
94 | ;; define a Version header properly; package.el also supports the | |
95 | ;; extension headers Package-Version (in case Version is an RCS id | |
96 | ;; or similar), and Package-Requires (if the package requires other | |
97 | ;; packages). | |
98 | ;; | |
99 | ;; M-x package-install-file | |
100 | ;; Install a package from the indicated file. The package can be | |
101 | ;; either a tar file or a .el file. A tar file must contain an | |
102 | ;; appropriately-named "-pkg.el" file; a .el file must be properly | |
103 | ;; formatted as with package-install-from-buffer. | |

118 | ;;; ToDo: | |
119 | ||
120 | ;; - putting info dirs at the start of the info path means | |
121 | ;; users see a weird ordering of categories. OTOH we want to | |
122 | ;; override later entries. maybe emacs needs to enforce | |
123 | ;; the standard layout? | |
124 | ;; - put bytecode in a separate directory tree | |
125 | ;; - perhaps give users a way to recompile their bytecode | |
126 | ;; or do it automatically when emacs changes | |
127 | ;; - give users a way to know whether a package is installed ok | |
128 | ;; - give users a way to view a package's documentation when it | |
129 | ;; only appears in the .el | |
130 | ;; - use/extend checkdoc so people can tell if their package will work | |
131 | ;; - "installed" instead of a blank in the status column | |
132 | ;; - tramp needs its files to be compiled in a certain order. | |
133 | ;; how to handle this? fix tramp? | |
134 | ;; - on emacs 21 we don't kill the -autoloads.el buffer. what about 22? | |
135 | ;; - maybe we need separate .elc directories for various emacs versions | |
136 | ;; and also emacs-vs-xemacs. That way conditional compilation can | |
137 | ;; work. But would this break anything? | |
138 | ;; - should store the package's keywords in archive-contents, then | |
139 | ;; let the users filter the package-menu by keyword. See | |
140 | ;; finder-by-keyword. (We could also let people view the | |
141 | ;; Commentary, but it isn't clear how useful this is.) | |
142 | ;; - William Xu suggests being able to open a package file without | |
143 | ;; installing it | |
144 | ;; - Interface with desktop.el so that restarting after an install | |
145 | ;; works properly | |
146 | ;; - Implement M-x package-upgrade, to upgrade any/all existing packages | |
147 | ;; - Use hierarchical layout. PKG/etc PKG/lisp PKG/info | |
148 | ;; ... except maybe lisp? | |
149 | ;; - It may be nice to have a macro that expands to the package's | |
150 | ;; private data dir, aka ".../etc". Or, maybe data-directory | |
151 | ;; needs to be a list (though this would be less nice) | |
152 | ;; a few packages want this, eg sokoban | |
153 | ;; - package menu needs: | |
154 | ;; ability to know which packages are built-in & thus not deletable | |
155 | ;; it can sometimes print odd results, like 0.3 available but 0.4 active | |
156 | ;; why is that? | |
157 | ;; - Allow multiple versions on the server...? | |
158 | ;; [ why bother? ] | |
159 | ;; - Don't install a package which will invalidate dependencies overall | |
160 | ;; - Allow something like (or (>= emacs 21.0) (>= xemacs 21.5)) | |
161 | ;; [ currently thinking, why bother.. KISS ] | |
162 | ;; - Allow optional package dependencies | |
163 | ;; then if we require 'bbdb', bbdb-specific lisp in lisp/bbdb | |
164 | ;; and just don't compile to add to load path ...? | |
165 | ;; - Have a list of archive URLs? [ maybe there's no point ] | |
166 | ;; - David Kastrup pointed out on the xemacs list that for GPL it | |
167 | ;; is friendlier to ship the source tree. We could "support" that | |
168 | ;; by just having a "src" subdir in the package. This isn't ideal | |
169 | ;; but it probably is not worth trying to support random source | |
170 | ;; tree layouts, build schemes, etc. | |
171 | ;; - Our treatment of the info path is somewhat bogus | |
172 | ;; - perhaps have an "unstable" tree in ELPA as well as a stable one | |
