PACKAGE is a symbol; the package's name.
|
|
WHEN should be one of the following:
|
|
:pre-init :post-init :pre-config :post-config
|
|
|
|
WARNINGS:
|
|
- The use of this macro is more often than not a code smell. Use it as last
|
|
resort. There is almost always a better alternative.
|
|
- If you are using this solely for :post-config, stop! `after!' is much better.
|
|
- If :pre-init or :pre-config hooks return nil, the original `use-package!''s
|
|
:init/:config block (respectively) is overwritten, so remember to have them
|
|
return non-nil (or exploit that to overwrite Doom's config)."

PACKAGE is a symbol or list of them. These are package names, not modes,
|
|
functions or variables. It can be:
|
|
|
|
- An unquoted package symbol (the name of a package)
|
|
(after! helm BODY...)
|
|
- An unquoted list of package symbols (i.e. BODY is evaluated once both magit
|
|
and git-gutter have loaded)
|
|
(after! (magit git-gutter) BODY...)
|
|
- An unquoted, nested list of compound package lists, using any combination of
|
|
:or/:any and :and/:all
|
|
(after! (:or package-a package-b ...) BODY...)
|
|
(after! (:and package-a package-b ...) BODY...)
|
|
(after! (:and package-a (:or package-b package-c) ...) BODY...)

Without :or/:any/:and/:all, :and/:all are implied.

1. Suppresses warnings for disabled packages at compile-time

2. No-ops for package that are disabled by the user (via `package!')

3. Supports compound package statements (see below)
