Features are: -;; -;; - Starts a eshell if non is existing. -;; -;; - Minimum distortion of your window configuration. -;; -;; - When done in the eshell-buffer you are returned to the same -;; window configuration you had before you toggled to the eshell. -;; -;; - If you desire, you automagically get a "cd" command in the -;; eshell to the directory where your current buffers file exists; -;; just call eshell-toggle-cd instead of eshell-toggle. -;; -;; - You can convinently choose if you want to have the eshell in -;; another window or in the whole frame. Just invoke eshell-toggle -;; again to get the eshell in the whole frame. -;; -;; This file has been tested under Emacs 20.2. -;; -;; To use, call the functions `eshell-toggle' or `eshell-toggle-cd'. -;; It's most helpful to bind these to a key. - -;;; Thanks to: - -;; Christian Stern <Christian.Stern@physik.uni-regensburg.de> for -;; helpful sugestions. - -;;; User Variables: - -(defvar eshell-toggle-goto-eob t - "*If non-nil `eshell-toggle' moves point to end of Eshell buffer. -When `eshell-toggle-cd' is called the point is always moved to the -end of the eshell-buffer") - -(defvar eshell-toggle-automatic-cd t - "*If non-nil `eshell-toggle-cd' will send a \"cd\" to Eshell. -If nil `eshell-toggle-cd' will only insert the \"cd\" command in the -eshell-buffer.
