use-package :custom causes gnus to load

use-package :custom causes gnus to load

[Juan José García-Ripoll]

Hi,

I have a stupid peeve with my current configuration, which relies on
`use-package` to defer loading of `gnus`, but still configuring relevant
parameters.

I have found that all of the :custom statements are fine, except for

:custom
(gnus-select-method '(nnnil ""))

It seems this custom statement triggers loading of gnus. I found this
can be used by replacing this statement with

:config
(setq gnus-select-method '(nnnil ""))

However, it is less than satisfactory.

Any clue about this?

Why is that?

(use-package gnus
  :init
  (add-hook 'gnus-group-mode-hook 'gnus-topic-mode)

  :config
  (setq gnus-select-method '(nnnil ""))
    (setq gnus-secondary-select-methods
        '((nntp "news.gmane.io")
  --snip--

I don't have any issues with this configuration.

I also configure gnus with a similar use-package block.
No issue here, Gnus isn't loaded.
Even when I use setopt.

Your below example shows using :config and an explicit setq statement to
change the value of that variable. I found that this approach *does not*
trigger loading gnus, but using the :custom field of use-package does. I
cannot really fathom why.

While setopt also uses custom but still doesn't trigger the loading
of gnus.

So you want the variable set, but without invoking Gnus? What's your
purpose in doing so?

According to documentation:

>:config can be used to execute code after a package is loaded.

So, the `:custom` option executes code before the package is loaded.
