Treemacs: Binding keys in treemacs-evil

Created on 9 Jul 2019 · 4Comments · Source: Alexander-Miller/treemacs

I would love to bind l and h (vim's left/right) to act as toggling directory open close, similar to treemacs-RET-action or treemacs-TAB-action. However, treemacs does not respect the following configuration code and defaults to its behavior:

    (define-key treemacs-mode-map (kbd "l") 'treemacs-TAB-action)
    (define-key treemacs-mode-map (kbd "h") treemacs-TAB-action)

Am I missing something, or is this potentially a bug?

@ludvikn h should be bound to treemacs-root-up. Is treemacs-evil installed and loaded properly?

Not a bug, just keymaps being complex, especially when evil is involved. Treemacs has its own evil state, so you should do something like this:

(evil-define-key 'treemacs treemacs-mode-map (kbd "h") #'treemacs-TAB-action)

Thanks @Alexander-Miller it works like a charm now! (Btw. great package! Enjoying a lot)

I'll close the issue.

I am having the same issue, but your binding does not do it for me.

I am using
(evil-define-key 'treemacs treemacs-mode-map (kbd "h") #'treemacs-TAB-action), but when I use describe-key for h and l emacs tells me they are still bound to evil-backward-char and evil-forward-char. Do you have any further suggestions?
