I argue that it is the best shell/command interpreter to use in -Emacs. - -Eshell is unlike the alternatives in Emacs as it's a /shell/ first, -not a terminal emulator. It has the ability to spoof some aspects of a -terminal emulator (through the shell parser), but it is NOT a terminal -emulator. - -The killer benefits of eshell (which would appeal to Emacs users) are -a direct result of eshell being written in Emacs lisp: -- incredible integration with Emacs utilities (such as ~dired~, - ~find-file~, any read functions, etc) -- very extensible, easy to write new commands which leverage Emacs - commands as well as external utilities -- agnostic of platform: "eshell/cd" will call the underlying change - directory function for you, so commands will (usually) mean the same - thing regardless of platform - - this means as long as Emacs can run on an operating system, one - may run eshell - -However, my favourite feature of eshell is the set of evaluators that -run on command input. Some of the benefits listed above come as a -result of this powerful feature. These evaluators are described below. - -Lisp evaluator: works on braced expressions, evaluating them as Lisp -expressions (e.g. ~(message "Hello, World!\n")~). Any returned -objects are printed. This makes eshell a LISP REPL! - -External evaluator: works within curly braces, evaluating them via -some external shell process (like sh) (e.g. ~{echo "Hello, -world!\n"}~). This makes eshell a (kinda dumb) terminal emulator! - -The alias evaluator is the top level evaluator. It is the main -evaluator for each expression given to eshell. When given an -expression it tries to evaluate it by testing against these conditions: -- it's an alias defined by the user or in the ~eshell/~ namespace of - functions (simplest evaluator) -- it's some form of lisp expression (lisp evaluator) -- it's an external command (bash evaluator) -Essentially, you get the best of both Emacs and external shell -programs *ALL WITHIN* Emacs for free. -** Eshell functionality -Bind some evil-like movements for easy shell usage, and a toggle -function to pull up the eshell quickly. -#+begin_src emacs-lisp -(use-package eshell - :commands +shell/toggle-eshell - :general - (shell-leader - "t" #'+shell/toggle-eshell) - :init - (add-hook - 'eshell-mode-hook - (proc - (interactive) - (general-def - :states '(normal insert) - :keymaps 'eshell-mode-map - "M-j" #'eshell-next-matching-input-from-input - "M-k" #'eshell-previous-matching-input-from-input) - (local-leader - :keymaps 'eshell-mode-map - "c" (proc (interactive) (eshell/clear) - (recenter)) - "k" #'eshell-kill-process))) - :config - (+oreo/create-toggle-function - +shell/toggle-eshell - "*eshell*" - eshell - t)) -#+end_src -** Eshell pretty symbols and display -Pretty symbols and a display record. -#+begin_src emacs-lisp -(use-package eshell - :defer t - :pretty - (eshell-mode-hook - ("lambda" .
