| 428 | 37 ;; |
| 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. | |
