使用 magit 快速 commit 和 push

magit 在 emacs 生态里是一大神器，当我们编辑当前项目文件，并且想对当前文件提交 commit 并 push，如何做？很简单使用下面的 aborn/simple-git-commit-push 命令就能达到效果！

(defun aborn/simple-git-commit-push (msg)
  "Simple commit current git project and push to its upstream."
  (interactive "sCommit Message: ")
  (when (= 0 (length msg))
    (setq msg (format-time-string "commit by magit in emacs@%Y-%m-%d %H:%M:%S"
                                  (current-time))))
  (message "commit message is %s" msg)
  (when (and buffer-file-name
             (buffer-modified-p))
    (save-buffer))                   ;; save it first if modified.
  (magit-stage-modified)
  (magit-commit (list "-m" msg))
  (magit-push-current-to-upstream nil))

将上面的 elisp 代码放到你的 init.el 文件里，当想 commit 时，执行:

M-x aborn/simple-git-commit-push

然后跳出一个交互输入：

当输入完 commit 信息后，回车！然后就会做异步的 commit 和 push（不会卡住当前 emacs 操作）。相当于执行了命令行下的以下两个命令：

git commit -am "your message"
git push

注意：

1. 你可以不填写 commit 信息，这时会自动生成一个 commit 信息!
2. 异步执行的日志信息在 magit-process: xxx 的一个 buffer 里。
