運行沒有Emacs的elisp程序？

Question

elisp的是一個良好的語言，我覺得它可以處理所有類型的工作，但我可以用它像一個shell腳本？

即從控制檯執行一些* .el文件，而無需啓動Emacs的。或者啓動Emacs，但不要進入交互模式。

可以最肯定不啓動編輯器界面運行在Emacs elisp的腳本。

這裏是在S.O.從幾個非常有用的Q &複製爲關於這個問題我在這裏所做的筆記/ （特別是以下兩個）。

• Emacs shell scripts - how to put initial options into the script?
• Idomatic batch processing of text in Emacs?

;;;; Elisp executable scripts 

;; --batch vs --script 
;; M-: (info "(emacs) Initial Options") RET 
;; M-: (info "(elisp) Batch Mode") RET 

;; Passing additional command-line arguments to Emacs: 
;; https://stackoverflow.com/questions/6238331/#6259330 
;; 
;; For robustness, it's important to both pass '--' as an argument 
;; (to prevent Emacs from trying to process option arguments intended 
;; for the script), and also set "argv" to nil at the end of the script 
;; (to prevent Emacs from visiting the non-option arguments as files). 
;; 
;; #!/bin/sh 
;; ":"; exec emacs --no-site-file --script "$0" -- "$@" # -*-emacs-lisp-*- 
;; (print (+ 2 2)) 
;; (setq argv nil) ;; always end with this 

;; Processing with STDIN and STDOUT via --script: 
;; https://stackoverflow.com/questions/2879746/#2906967 
;; 
;; #!/usr/local/bin/emacs --script 
;; ;;-*- mode: emacs-lisp;-*- 
;; 
;; (defun process (string) 
;; "just reverse the string" 
;; (concat (nreverse (string-to-list string)))) 
;; 
;; (condition-case nil 
;;  (let (line) 
;;  ;; commented out b/c not relevant for `cat`, but potentially useful 
;;  ;; (princ "argv is ") 
;;  ;; (princ argv) 
;;  ;; (princ "\n") 
;;  ;; (princ "command-line-args is") 
;;  ;; (princ command-line-args) 
;;  ;; (princ "\n") 
;; 
;;  (while (setq line (read-from-minibuffer "")) 
;;   (princ (process line)) 
;;   (princ "\n"))) 
;; (error nil)) 

Emacs的一邊，只有其他的elisp解釋/編譯我所知道的是狡詐。如果你熱衷於在elisp的一般編碼，這應該是值得一試（特別是如果性能是一個問題）。
