| 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 it's 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 |
| 61 | ;;; familiar with it already) |
