32 ;; This package is for running a remote compilation and using emacs to parse
|
|
|
33 ;; the error messages. It works by rsh'ing the compilation to a remote host
|
|
|
34 ;; and parsing the output. If the file visited at the time remote-compile was
|
|
|
35 ;; called was loaded remotely (ange-ftp), the host and user name are obtained
|
|
|
36 ;; by the calling ange-ftp-ftp-name on the current directory. In this case the
|
|
|
37 ;; next-error command will also ange-ftp the files over. This is achieved
|
|
|
38 ;; automatically because the compilation-parse-errors function uses
|
|
|
39 ;; default-directory to build it's file names. If however the file visited was
|
|
|
40 ;; loaded locally, remote-compile prompts for a host and user and assumes the
|
|
|
41 ;; files mounted locally (otherwise, how was the visited file loaded).

45 ;; I was contemplating redefining "compile" to "remote-compile" automatically
|
|
|
46 ;; if the file visited was ange-ftp'ed but decided against it for now. If you
|
|
|
47 ;; feel this is a good idea, let me know and I'll consider it again.

|
|
50
|
|
2
|
51 ;; To use rcompile, you also need to give yourself permission to connect to
|
|
|
52 ;; the remote host. You do this by putting lines like:
|
|
0
|
53
|
|
2
|
54 ;; monopoly alon
|
|
|
55 ;; vme33
|
|
|
56 ;;
|
|
|
57 ;; in a file named .rhosts in the home directory (of the remote machine).
|
|
|
58 ;; Be careful what you put in this file. A line like:
|
|
|
59 ;;
|
|
|
60 ;; +
|
|
|
61 ;;
|
|
|
62 ;; Will allow anyone access to your account without a password. I suggest you
|
|
|
63 ;; read the rhosts(5) manual page before you edit this file (if you are not
|
|
|
64 ;; familiar with it already)
