||
;;; 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)
