Starter Kit Eshell

Eshell is a great shell.

     (require 'em-cmpl)

     (require 'em-term)
     ;; TODO: for some reason requiring this here breaks it, but
     ;; requiring it after an eshell session is started works fine.
     ;; (require 'eshell-vc)
     (setenv "PAGER" "cat")
     ; (set-face-attribute 'eshell-prompt nil :foreground "turquoise1")
     (add-hook 'eshell-mode-hook ;; for some reason this needs to be a hook
               '(lambda () (define-key eshell-mode-map "\C-a" 'eshell-bol)))
     (add-to-list 'eshell-visual-commands "ssh")
     (add-to-list 'eshell-visual-commands "tail")
     (add-to-list 'eshell-command-completions-alist
                  '("gunzip" "gz\\'"))
     (add-to-list 'eshell-command-completions-alist
                  '("tar" "\\(\\.tar|\\.tgz\\|\\.tar\\.gz\\)\\'"))

The eshell directory holds alias definitions and history information. It is much like a .bashrc file for those who are familiar with bash. This set the value of eshell-directory-name to point to the eshell directory in this directory. The alias file is pre-populated with some generally applicable aliases.

(setq eshell-directory-name (expand-file-name "./" (expand-file-name "eshell" dotfiles-dir)))
