|
31 ;;; This package is for running a remote compilation and using emacs to parse
|
|
|
32 ;;; the error messages. It works by rsh'ing the compilation to a remote host
|
|
|
33 ;;; and parsing the output. If the file visited at the time remote-compile was
|
|
|
34 ;;; called was loaded remotely (ange-ftp), the host and user name are obtained
|
|
|
35 ;;; by the calling ange-ftp-ftp-name on the current directory. In this case the
|
|
|
36 ;;; next-error command will also ange-ftp the files over. This is achieved
|
|
|
37 ;;; automatically because the compilation-parse-errors function uses
|
|
|
38 ;;; default-directory to build it's file names. If however the file visited was
|
|
|
39 ;;; loaded locally, remote-compile prompts for a host and user and assumes the
|
|
|
40 ;;; files mounted locally (otherwise, how was the visited file loaded).
|
|
|
41
|
|
|
42 ;;; See the user defined variables section for more info.
|
|
|
43
|
|
|
44 ;;; I was contemplating redefining "compile" to "remote-compile" automatically
|
|
|
45 ;;; if the file visited was ange-ftp'ed but decided against it for now. If you
|
|
|
46 ;;; feel this is a good idea, let me know and I'll consider it again.
|
|
|
47
|
|
|
48 ;;; Installation:
|
|
|
49
|
|
|
50 ;;; To use rcompile, you also need to give yourself permission to connect to
|
|
|
51 ;;; the remote host. You do this by putting lines like:
|
|
|
52
|
|
|
53 ;;; monopoly alon
|
|
|
54 ;;; vme33
|
|
|
55 ;;;
|
|
|
56 ;;; in a file named .rhosts in the home directory (of the remote machine).
|
|
|
57 ;;; Be careful what you put in this file. A line like:
|
|
|
58 ;;;
|
|
|
59 ;;; +
|
|
|
60 ;;;
|
|
|
61 ;;; Will allow anyone access to your account without a password. I suggest you
|
|
|
62 ;;; read the rhosts(5) manual page before you edit this file (if you are not
|
|
|
63 ;;; familiar with it already)
