32 | ;; This Lisp code is run in Emacs when it is to operate as |
33 | ;; a server for other processes. | |
9ae0f972 | 34 | |
b578f267 | 35 | ;; Load this library and do M-x server-edit to enable Emacs as a server. |
44a56b29 SM |
36 | ;; Emacs opens up a socket for communication with clients. If there are no |
37 | ;; client buffers to edit, server-edit acts like (switch-to-buffer | |
38 | ;; (other-buffer)) | |
9ae0f972 | 39 | |
b578f267 EN |
40 | ;; When some other program runs "the editor" to edit a file, |
41 | ;; "the editor" can be the Emacs client program ../lib-src/emacsclient. | |
42 | ;; This program transmits the file names to Emacs through | |
43 | ;; the server subprocess, and Emacs visits them and lets you edit them. | |
9ae0f972 | 44 | |
b578f267 | 45 | ;; Note that any number of clients may dispatch files to emacs to be edited. |
9ae0f972 | 46 | |
b578f267 | 47 | ;; When you finish editing a Server buffer, again call server-edit |
64f51134 JPW |
48 | ;; to mark that buffer as done for the client and switch to the next |
49 | ;; Server buffer. When all the buffers for a client have been edited | |
b578f267 | 50 | ;; and exited with server-edit, the client "editor" will return |
64f51134 | 51 | ;; to the program that invoked it. |
9ae0f972 | 52 | |
b578f267 EN |
53 | ;; Your editing commands and Emacs's display output go to and from |
54 | ;; the terminal in the usual way. Thus, server operation is possible | |
55 | ;; only when Emacs can talk to the terminal at the time you invoke | |
56 | ;; the client. This is possible in four cases: | |
9ae0f972 | 57 | |
b578f267 EN |
58 | ;; 1. On a window system, where Emacs runs in one window and the |
59 | ;; program that wants to use "the editor" runs in another. | |
9ae0f972 | 60 | |
b578f267 EN |
61 | ;; 2. On a multi-terminal system, where Emacs runs on one terminal and the |
62 | ;; program that wants to use "the editor" runs on another. | |
9ae0f972 | 63 | |
b578f267 EN |
64 | ;; 3. When the program that wants to use "the editor" is running |
65 | ;; as a subprocess of Emacs. | |
9ae0f972 | 66 | |
b578f267 EN |
67 | ;; 4. On a system with job control, when Emacs is suspended, the program |
68 | ;; that wants to use "the editor" will stop and display | |
69 | ;; "Waiting for Emacs...". It can then be suspended, and Emacs can be | |
70 | ;; brought into the foreground for editing. When done editing, Emacs is | |
71 | ;; suspended again, and the client program is brought into the foreground. | |
9ae0f972 | 72 | |
64f51134 JPW |
73 | ;; The buffer local variable "server-buffer-clients" lists |
74 | ;; the clients who are waiting for this buffer to be edited. | |
b578f267 EN |
75 | ;; The global variable "server-clients" lists all the waiting clients, |
76 | ;; and which files are yet to be edited for each. | |
