The conditionals in the `fill-column` module used the raw version number, this
commit changes them to use the macro provided by DOOM.
Suggested by @gagbo
Emacs 27 introduced `display-fill-column-indicator-mode` which replaces
`hl-fill-column`. This commit adds some conditionals to use
`display-fill-column-indicator-mode` on Emacs 27+, or falls back to
`hl-fill-column-mode` on older versions.
This update may potentially break your usage of add-hook! if you pass
the :local or :append properties to it. This is how they used to work:
(add-hook! :append 'some-mode-hook #'do-something)
Thsoe properties must now follow the hooks, e.g.
(add-hook! 'some-mode-hook :append #'do-something)
Other changes:
- Various add-hook calls have been renamed to add-hook! because I
incorrectly assumed `defun` always returned its definition's symbol,
when in fact, its return value is "undefined" (so sayeth the
documentation). This should fix#1597.
- This update adds the ability to add multiple functions to hooks
without a list:
(add-hook! 'some-mode-hook
#'do-something
#'do-something-else)
- The indentation logic has been changed so that consecutive function
symbols at indented at the same level as the first argument, but forms
are indent like a defun.
(add-hook! 'some-mode-hook
#'do-something
#'do-something-else)
(add-hook! 'some-mode-hook
(message "Hello"))
