An independent package with this shell startup setup could be made: not dependent on the Emacs package, so that it could be used on remote systems accessed through Emacs. The commentaries: ;;; With this enhanced ansi-term.el you will get a reliable mechanism of ;;; directory/username/host tracking: the only drawback is that you will ;;; have to modify your shell start-up script. It's worth it, believe me :). ;;; ;;; When you rlogin/su/telnet and the account you access has a modified ;;; startup script, you will be able to access the remote files as usual ;;; with C-x C-f, if it's needed you will have to enter a password, ;;; otherwise the file should get loaded straight away. ;;; ;;; This is useful even if you work only on one host: it often happens that, ;;; for maintenance reasons, you have to edit files 'as root': before ;;; patching term.el, I su-ed in a term.el buffer and used vi :), now I ;;; simply do a C-x C-f and, via ange-ftp, the file is automatically loaded ;;; 'as-root'. .... ;;; Notice: for directory/host/user tracking you need to have something ;;; like this in your shell startup script ( this is for tcsh but should ;;; be quite easy to port to other shells ) ;;; ;;; ---------------------------------------- ;;; ;;; ;;; set os = `uname` ;;; set host = `hostname` ;;; set date = `date` ;;; ;;; # su does not change this but I'd like it to ;;; ;;; set user = `whoami` ;;; ;;; # ... ;;; ;;; if ( eterm =~ $TERM ) then ;;; ;;; echo -------------------------------------------------------------- ;;; echo Hello $user ;;; echo Today is $date ;;; echo We are on $host running $os under Emacs term mode ;;; echo -------------------------------------------------------------- ;;; ;;; setenv EDITOR emacsclient ;;; ;;; # Notice: $host and $user have been set before to 'hostname' and 'whoami' ;;; # this is necessary because, f.e., certain versions of 'su' do not change ;;; # $user, YMMV: if you don't want to fiddle with them define a couple ;;; # of new variables and use these instead. ;;; # NOTICE that there is a space between "AnSiT?" and $whatever NOTICE ;;; ;;; # These are because we want the real cwd in the messages, not the login ;;; # time one ! ;;; ;;; set cwd_hack='$cwd' ;;; set host_hack='$host' ;;; set user_hack='$user' ;;; ;;; # Notice that the ^[ character is an ESC, not two chars.
