Emacs 21.1 comes with a powerful package, eshell. This is a very
powerful package. It should have been included earlier. I have
been suffering all these years without a proper shell. The only
short coming is, eshell does not support input redirection.
Although it is great, I still have to write some lisp codes to
fix a few things that borther me.
EShell Environment Settings
You may type alt-x eshell to invoke eshell. To set the
path and environment correctly, you may want to put this
into your .emacs file.
(setq path ".;c:/program files/microsoft visual studio/vb98/")
(setq path (concat path ";d:/program files/microsoft visual studio/vc98/bin"))
(setenv "PATH" path))
(local-set-key "\C-u" 'eshell-kill-input))
Running Perl Scripts in EShell
Eshell does not recognize perl script extensions.
So I have to do this.
;; To make eshell understand .pl perl extensions.
(add-hook 'eshell-named-command-hook 'n-eshell-exec-perl)
(defun n-eshell-exec-perl (command args)
"04Dec2001 - sailor, to make eshell understand perl scripts."
(if (string-match "^.+\.pl[ \t]*" command)
(setq args (cons command args))
(setq args (cons "-S" args))
(eshell-parse-command "perl" args))
Clearing EShell Buffer
When the eshell buffer gets too large, you can simple type
the command clear within the eshell to clear the entire buffer.
(defun eshell/clear ()
"04Dec2001 - sailor, to clear the eshell buffer."
(let ((inhibit-read-only t))
