|
|
|
38 ;; The idea:
|
|
|
39 ;; A new XEmacs lisp-only release is generated with the following steps:
|
|
|
40 ;; 1. The maintainer runs some yet to be written program that
|
|
|
41 ;; generates all the dependency information. This should
|
|
|
42 ;; determine all the require and provide statements and associate
|
|
|
43 ;; them with a package.
|
|
|
44 ;; 2. All the packages are then bundled into their own tar balls
|
|
|
45 ;; (or whatever format)
|
|
|
46 ;; 3. Maintainer automatically generates a new `package-get-base'
|
|
|
47 ;; data structure which contains information such as the
|
|
|
48 ;; package name, the file to be retrieved, an md5 checksum,
|
|
|
49 ;; etc (see `package-get-base').
|
|
|
50 ;; 4. The maintainer posts an announcement with the new version
|
|
|
51 ;; of `package-get-base'.
|
|
|
52 ;; 5. A user/system manager saves this posting and runs
|
|
|
53 ;; `package-get-update' which uses the previously saved list
|
|
|
54 ;; of packages, `package-get-here' that the user/site
|
|
|
55 ;; wants to determine what new versions to download and
|
|
|
56 ;; install.
|
|
|
57 ;;
|
|
|
58 ;; A user/site manager can generate a new `package-get-here' structure
|
|
|
59 ;; by using `package-get-setup' which generates a customize like
|
|
|
60 ;; interface to the list of packages. The buffer looks something
|
|
|
61 ;; like:
|
|
|
62 ;;
|
|
|
63 ;; gnus - a mail and news reader
|
|
|
64 ;; [] Always install
|
|
|
65 ;; [] Needs updating
|
|
|
66 ;; [] Required by other [packages]
|
|
|
67 ;; version: 2.0
|
|
|
68 ;;
|
|
|
69 ;; vm - a mail reader
|
|
|
70 ;; [] Always install
|
|
|
71 ;; [] Needs updating
|
|
442
|
72 ;; [] Required by other [packages]
|
|
428
|
73 ;;
|
|
|
74 ;; Where `[]' indicates a toggle box
|
|
|
75 ;;
|
|
|
76 ;; - Clicking on "Always install" puts this into
|
|
|
77 ;; `package-get-here' list. "Needs updating" indicates a new
|
|
|
78 ;; version is available. Anything already in
|
|
|
79 ;; `package-get-here' has this enabled.
|
|
|
80 ;; - "Required by other" means some other packages are going to force
|
|
|
81 ;; this to be installed. Clicking on [packages] gives a list
|
|
|
82 ;; of packages that require this.
|
|
442
|
83 ;;
|
|
428
|
84 ;; The `package-get-base' should be installed in a file in
|
|
|
85 ;; `data-directory'. The `package-get-here' should be installed in
|
|
|
86 ;; site-lisp. Both are then read at run time.
|
|
|
87 ;;
|
|
|
88 ;; TODO:
|
|
|
89 ;; - Implement `package-get-setup'
|
|
|
90 ;; - Actually put `package-get-base' and `package-get-here' into
|
|
|
91 ;; files that are read.
|
|
|
92 ;; - Allow users to have their own packages that they want installed
|
|
|
93 ;; in ~/.xemacs/.
|
|
|
94 ;; - SOMEONE needs to write the programs that generate the
|
|
|
95 ;; provides/requires database and makes it into a lisp data
|
|
|
96 ;; structure suitable for `package-get-base'
|
|
|
97 ;; - Handle errors such as no package providing a required symbol.
|
|
|
98 ;; - Tie this into the `require' function to download packages
|
|
|
99 ;; transparently.
