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