27 | ;;; Commentary: | |
28 | ||
29 | ;; This package is for running a remote compilation and using emacs to parse | |
30 | ;; the error messages. It works by rsh'ing the compilation to a remote host | |
31 | ;; and parsing the output. If the file visited at the time remote-compile was | |
32 | ;; called was loaded remotely (ange-ftp), the host and user name are obtained | |
33 | ;; by the calling ange-ftp-ftp-name on the current directory. In this case the | |
34 | ;; next-error command will also ange-ftp the files over. This is achieved | |
35 | ;; automatically because the compilation-parse-errors function uses | |
36 | ;; default-directory to build its file names. If however the file visited was | |
37 | ;; loaded locally, remote-compile prompts for a host and user and assumes the | |
38 | ;; files mounted locally (otherwise, how was the visited file loaded). | |
39 | ||
40 | ;; See the user defined variables section for more info. | |
41 | ||
42 | ;; I was contemplating redefining "compile" to "remote-compile" automatically | |
43 | ;; if the file visited was ange-ftp'ed but decided against it for now. If you | |
44 | ;; feel this is a good idea, let me know and I'll consider it again. | |
45 | ||
46 | ;; Installation: | |
47 | ||
48 | ;; To use rcompile, you also need to give yourself permission to connect to | |
49 | ;; the remote host. You do this by putting lines like: | |
50 | ||
51 | ;; monopoly alon | |
52 | ;; vme33 | |
53 | ;; | |
54 | ;; in a file named .rhosts in the home directory (of the remote machine). | |
55 | ;; Be careful what you put in this file. A line like: | |
56 | ;; | |
57 | ;; + | |
58 | ;; | |
59 | ;; Will allow anyone access to your account without a password. I suggest you | |
60 | ;; read the rhosts(5) manual page before you edit this file (if you are not | |
a1506d29 | 61 | ;; familiar with it already) |
