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 + :defer t + :general + (shell-leader + "t" #'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)))) +#+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" .
