用git 来管理emacs配置文件

廖雪峰的Git教程

外部程序修改init.el 自动重新加载

(global-auto-revert-mode t)

禁止auto save

(setq auto-save-default nil)

光标自动出现在新的窗口

(require 'popwin)
(popwin-mode t)

autoload

;;;###autoload
(define-globalized-minor-mode global-company-mode company-mode company-mode-on)

(defun company-mode-on ()
(when (and (not (or noninteractive (eq (aref (buffer-name) 0) ?\s)))
(cond ((eq company-global-modes t)
t)
((eq (car-safe company-global-modes) 'not)
(not (memq major-mode (cdr company-global-modes))))
(t (memq major-mode company-global-modes))))
(company-mode 1)))

(defsubst company-assert-enabled ()
(unless company-mode
(company-uninstall-map)
(user-error "Company not enabled")))

(package-initialize)

company-autoloads.el

扫描所有的魔法注释生成autloads.el 可以不require 调用

features, provide and require, autoload

Emacs Lisp: require, load, load-file, autoload, feature, Explained

abbrev-mode

(abbrev-mode t)
(define-abbrev-table 'global-abbrev-table '(
;; signature
("8zl" "zilongshanren")
;; emacs regex
))

输入8zl 后按空格会补全
