* Description
|
|
This layer enhances the default commands of Emacs and is primarily intended to
|
|
be used with the =emacs= editing style as it does not change anything in the Vim
|
|
key bindings.
|
|
|
|
However the =emacs= editing style is not required. You can still use this layer
|
|
while you are using the =vim= editing style if you have some kind of mixed
|
|
style, but some of the layer bindings might be shadowed by the evil key bindings.
|
|
|
|
The commands defined in this layer are taken from various sources like [[https://github.com/bbatsov/prelude][Prelude]].
|
|
|
|
** Features:
|
|
- Smart line navigation: Subsequent presses of ~C-a~ toggles between the beginning of the line and the first non-whitespace character. Similarly, subsequent presses of ~C-e~ will toggle between the end of the code and the end of the comments.
|
|
- =spacemacs/backward-kill-word-or-region=: A combination of =kill-region= and =backward-kill-word=, depending on whether there is an active region. If there's an active region kill that. If not kill the preceding word.
|
|
- Fill or unfill paragraph: Pressing ~M-q~ for the first time fills current paragraph and pressing ~M-q~ for the second time unfills it. Note that some modes override this key binding so it's not available everywhere. Due to implementation details unfilling doesn't work when called twice via ~M-x~.

|
|
* Install
|
|
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
|
|
add =better-defaults= to the existing =dotspacemacs-configuration-layers= list in
|
|
this file.
|
|
|
|
* Configuration
|
|
Choose if ~C-a~ first brings you to the beginning of the line or the beginning of
|
|
the code (first non-whitespace character).
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(better-defaults :variables
|
|
better-defaults-move-to-beginning-of-code-first t)
|
|
#+END_SRC
|
|
|
|
Choose if ~C-e~ first brings you to the end of the line or the end of the code
|
|
(before or after comments).
|
|
|
|
#+BEGIN_SRC emacs-lisp
|
|
(better-defaults :variables
|
|
better-defaults-move-to-end-of-code-first nil)
|
|
#+END_SRC
