Why doesn’t persp-mode load on initialization?
reddit / emacs

I have this piece in my `init.el`

```
(use-package persp-mode
  :ensure t
  :custom (persp-mode-prefix-key (kbd "C-c w" ))
  :bind ("C-x C-b" . persp-list-buffers)
  :config
  (persp-mode)
  (setq persp-autokill-buffer-on-remove 'kill-weak)
  (add-hook 'window-setup-hook #'(lambda () (persp-mode 1))))
```

For some reason, persp-mode isn’t loaded on initialization. What’s
more interesting is it doesn’t load if I run `persp-mode` after Emacs
is loaded, I have to execute `persp-mode` _two_ times for it to work
properly. Working properly for me means that `C-c w` prefix works.

Any idea what I’m doing wrong?

UPDATE

Fixed, thanks to the commenters. I checked `persp-mode`
[document](https://github.com/Bad-ptr/persp-mode.el#keys) again and it
seems the prefix variable is now called `persp-keymap-prefix`
:facepalm:

Anyway, I also used what people mentioned below and this is my final
config that works.

```
(use-package persp-mode
  :ensure t
  :custom
  (persp-keymap-prefix (kbd "C-c w"))
  (persp-autokill-buffer-on-remove 'kill-weak)
  :bind ("C-x C-b" . persp-list-buffers)
  :demand t
  :config
  (persp-mode +1))
```

:config is evaluated after the package is loaded...

So? I'm calling \`(persp-mode)\` there so it should be ok?

Sorry if it's a noob question.

move (persp-mode) to :init

or better, write (persp-mode +1)

I might be wrong, but I believe that the :bind keyword automatically
lazy loads the package. Try adding `:demand t`, as per [the
docs](https://jwiegley.github.io/use-package/keywords/), so that it's
loaded guaranteed.

It wasn’t needed it seems. See my update in the post.

Thanks for the info! It seems it was indeed needed to add `:demand t`
too. I’ve updated the post with the final version that works for me.
