33 | ;; Goals: | |
34 | ;; | |
35 | ;; There is a class of front-ending problems that Emacs might be used | |
36 | ;; to address that involves selecting sets of files, or possibly | |
37 | ;; directories, and passing the selection set to slave commands. The | |
38 | ;; prototypical example, from which this code is derived, is talking | |
39 | ;; to version-control systems. | |
40 | ;; | |
41 | ;; vc-dispatcher.el is written to decouple the UI issues in such front | |
42 | ;; ends from their application-specific logic. It also provides a | |
43 | ;; service layer for running the slave commands either synchronously | |
44 | ;; or asynchronously and managing the message/error logs from the | |
45 | ;; command runs. | |
46 | ;; | |
47 | ;; Similar UI problems can be expected to come up in applications | |
48 | ;; areas other than VCSes; IDEs and document search are two obvious ones. | |
49 | ;; This mode is intended to ensure that the Emacs interfaces for all such | |
50 | ;; beasts are consistent and carefully designed. But even if nothing | |
51 | ;; but VC ever uses it, getting the layer separation right will be | |
52 | ;; a valuable thing. | |
53 | ||
54 | ;; Dispatcher's universe: | |
55 | ;; | |
56 | ;; The universe consists of the file tree rooted at the current | |
57 | ;; directory. The dispatcher's upper layer deduces some subset | |
58 | ;; of the file tree from the state of the currently visited buffer | |
59 | ;; and returns that subset, presumably to a client mode. | |
60 | ;; | |
61 | ;; The user may be attempting to select one of three contexts: an | |
62 | ;; explicitly selected fileset, the current working directory, or a | |
63 | ;; global (null) context. The user may be looking at either of two | |
64 | ;; different views; a buffer visiting a file, or a directory buffer | |
65 | ;; generated by vc-dispatcher. The main UI problem connected with | |
66 | ;; this mode is that the user may need to be able to select any of | |
67 | ;; these three contexts from either view. | |
68 | ;; | |
69 | ;; The lower layer of this mode runs commands in subprocesses, either | |
70 | ;; synchronously or asynchronously. Commands may be launched in one | |
71 | ;; of two ways: they may be run immediately, or the calling mode can | |
72 | ;; create a closure associated with a text-entry buffer, to be | |
73 | ;; executed when the user types C-c to ship the buffer contents. In | |
74 | ;; either case the command messages and error (if any) will remain | |
75 | ;; available in a status buffer. | |
76 | ||

77 | ;; Special behavior of dispatcher directory buffers: |
78 | ;; | |
79 | ;; In dispatcher directory buffers, faciltiies to perform basic | |
80 | ;; navigation and selection operations are provided by keymap and menu | |
81 | ;; entries that dispatcher sets up itself, so they'll be uniform | |
82 | ;; across all dispatcher- using client modes. Client modes are | |
83 | ;; expected to append to these to provide mode-specific bindings. | |
84 | ;; | |
85 | ;; The standard map associates a 'state' slot (that the client mode | |
86 | ;; may set) with each directory entry. The dispatcher knows nothing | |
87 | ;; about the semantics of individual states, but mark and unmark commands | |
88 | ;; treat all entries with the same state | |
89 | ||
90 | ;; To do: | |
91 | ;; | |
92 | ;; - vc-dir-kill-dir-status-process should not be specific to dir-status, | |
93 | ;; it should work for other async commands as well (pull/push/...). | |
94 | ;; | |
95 | ;; - the *VC-log* buffer needs font-locking. | |
96 | ;; | |
97 | ;; - Set `vc-dir-insert-directories' to t and check what operations | |
98 | ;; and backends do not support directory arguments and fix them. | |
99 | ;; | |
100 | ;; - vc-dir needs mouse bindings. | |
101 | ;; | |
102 | ;; - vc-dir needs more key bindings for VC actions. | |
103 | ;; | |
104 | ;; - vc-dir toolbar needs more icons. | |
105 | ;; | |
106 | ;; - vc-dir-next-line should not print an "end of buffer" message when | |
107 | ;; invoked with the cursor on the last file. | |
108 | ;; | |
109 | ;; - add commands to move to the prev/next directory in vc-dir. | |
110 | ;; | |
111 | ;; - document vc-dir in the manual. | |
