一个小设置：改变 eshell 的提示符

下面的小配置让 eshell 的 prompt 最多只显示最后 4 个文件夹名。

;; change eshell prompt
(defun yami-adjust-eshell-prompt (path)
(let* ( (path-components (split-string path "/"))
(len (length path-components))
(max-comp 4) )
(if (<= len max-comp)
path
(concat "<< " (mapconcat (lambda (str) str)
(nthcdr (- len max-comp) path-components)
"/")))))

(setq eshell-prompt-function
(lambda ()
(concat (yami-adjust-eshell-prompt (eshell/pwd))
(if (= (user-uid) 0) " # " " $ "))))

傻傻的效果，凑合着用先
