Can't move around ansi-term as if it's a typical buffer.

[giuscri]

Description :octocat:

Can't move around ansi-term as if it's a typical buffer.

Reproduction guide :beetle:

• Start Emacs
• SPC SPC ansi-term
• Run lscpu in shell (or anything else that prints a bunch of lines)

Observed behaviour: :eyes: :broken_heart: After pressing ESC, being in Normal again, pressing k doesn't allow me to go up one line in the buffer.

Expected behaviour: :heart: :smile: After pressing ESC, being in Normal again, pressing hjkl should allow me to move around in the buffer.

10844 might fix this.

The fix in #10844 should work now. I actually found it more convenient to set the buffer to read-only while in normal state, since the editing commands in normal state don't do anything useful. My config now looks like this:

(defun config//term-normal-state ()
  "Enable `term-line-mode' when in normal state in `term-mode' buffer
 and make the buffer read only."
  (term-line-mode)
  (read-only-mode 1))

(defun config//term-insert-state ()
  "Enable `term-char-mode' when in insert state in a `term-mode' buffer."
  (when (get-buffer-process (current-buffer))
    (read-only-mode -1)
    (term-char-mode)
    ))

(defun config//term-evil-bindings ()
  "Enable term support for vim and hybrid editing styles."
  (add-hook 'evil-hybrid-state-entry-hook 'config//term-insert-state nil t)
  (add-hook 'evil-insert-state-entry-hook 'config//term-insert-state nil t)
  (add-hook 'evil-hybrid-state-exit-hook 'config//term-normal-state nil t)
  (add-hook 'evil-insert-state-exit-hook 'config//term-normal-state nil t))

(setq term-char-mode-point-at-process-mark t)
(add-hook 'term-mode-hook 'config//term-evil-bindings)

This is still far from perfect. Ideally, the bindings in normal state should work as in shell-mode or other comint modes, where you can edit the input line while leaving the prompt intact. But this is not so easy since term-mode does not derive from comint-mode.

Any updates on this? :(

This fixed the problem for me: https://github.com/syl20bnr/spacemacs/issues/10779#issuecomment-427712967

summary: An Emacs 26.1 change causes this behavior, which can be fixed via a user-config setting.
