emacs - 为什么我的 term-mode-hook 没有选择行模式？

Question

我写了这个elisp函数:

(defun run (command)
  "Open a terminal running a command."
  (interactive "sCommand: ")
  (if (buffer-exists (concat "*" command "*" )) (kill-buffer (concat "*" command "*")))
  (let ((term-mode-hook (cons (lambda () (term-line-mode)) term-mode-hook)))
    (ansi-term (cons "sh" (cons "-i" (list "-c" command))) command)))

这很好地工作，除了新的 ansi-term 缓冲区保持在 char 模式(这是默认值)，据我所知， term-line-mode 调用没有做任何事情。如果我将 (term-line-mode) 替换为 (message "foo") 我确实会在消息缓冲区中看到该消息。

lisp/term.el 中 term-line-mode 的定义是:

(defun term-line-mode  ()
  "Switch to line (\"cooked\") sub-mode of term mode.
This means that Emacs editing commands work as normally, until
you type \\[term-send-input] which sends the current line to the inferior."
  (interactive)
  (when (term-in-char-mode)
    (use-local-map term-old-mode-map)
    (term-update-mode-line)))

我究竟做错了什么？

在任何术语 Hook 中，我都无法让“术语行模式”按照您的意愿工作；但是，如果您建议使用“ansi-term”功能，它确实有效:

(defadvice ansi-term (after advice-term-line-mode activate)
  (term-line-mode))
