I'm using the python-layer and am trying to set M-r to run replace-string while editing Python files. I've tried all of the options below from inside the function dotspacemacs/user-config. Help?

;; NONE OF THESE WORK!
(define-key evil-insert-state-map (kbd "M-r") 'replace-string)
(define-key evil-insert-state-map "\M-r" 'replace-string)
(spacemacs/set-leader-keys "M-r" 'replace-string)
(spacemacs/set-leader-keys-for-major-mode 'python-mode "M-r" 'replace-string)
(spacemacs/set-leader-keys-for-major-mode 'anaconda-mode "M-r" 'replace-string)
(defun my-python-mode-config ()
  "For use in `mode-hooks'."
  (local-set-key (kbd "M-r") `replace-string)
)
(add-hook 'python-mode-hook 'my-python-mode-config)
(add-hook 'anaconda-mode-hook 'my-python-mode-config)
(global-set-key "\M-r"  'replace-string)

I don't know anything about how Spacemacs works, but the attempts with global-set-key or evil-insert-state-map aren't supposed to work, because the local keymaps take precedence!

I think it should work to set it in the anaconda-mode-map. So you can modify the my-python-mode-config function to call (define-key anaconda-mode-map (kbd "M-r") 'replace-string) instead.

Although, instead of defining the key every single time you switch to anaconda-mode, the premature optimizer in me would do it only once:

(eval-after-load 'anaconda-mode
    '(define-key anaconda-mode-map (kbd "M-r") 'replace-string))

Finally, I vaguely remember that Spacemacs uses use-package. If that's the case you can add

:bind (:map anaconda-mode-map ("M-r" . replace-string))

to the (use-package anaconda-mode) form you must have somewhere in your config.

I just went through a similar ordeal trying to bind a key in ess-mode with spacemacs. Assuming you're using evil-mode, I think the following will work:

  (evil-define-key 'insert python-mode (kbd "M-r") 'replace-string)
0

(global-set-key (kbd "M-r") 'replace-string)

You can also set it the spacemacs way:

spacemacs/set-leader-keys-for-major-mode 'python-mode "oo" 'replace-string

and you can use it by SPACE o o.

  • Thanks but that doesn't work (you can see I tried that in the last line of my code). M-r is still bound to `anaconda-mode-find-references – Brep Brep Aug 11 '17 at 17:33
  • Did you add the kbd function before M-r ? – Ray Wang Aug 12 '17 at 3:44
  • Yup, I added that to my .spacemacs and restarted to no avail. – Brep Brep Aug 21 '17 at 14:28
