Quick start
Configuration layers
Spacemacs divides its configuration into self-contained units called
configuration layers. These layers are stacked on top of each other
to achieve a custom configuration.
By default Spacemacs uses a dotfile called ~/.spacemacs to control which
layers to load. Within this file you can also configure certain features.
A configuration layer is a directory containing at least a packages.el
file which defines and configures packages to be downloaded from Emacs
package repositories using the package.el built-in feature of Emacs.
If you already have your own Emacs configuration you can move it to your
own layer.
The following command creates a layer in the private directory:
<SPC> : configuration-layer/create-layer RET
Any configuration layers you create must be explicitly loaded in ~/.spacemacs.
Note: For your privacy, the contents of the private directory are not
under source control. See the section on private configuration management in
the documentation.
Dotfile (.spacemacs)
As mentioned .spacemacs controls which configuration layers to load and
is also a means to customizing Spacemacs.
The following command will create a .spacemacs file in your home directory:
<SPC> : dotspacemacs/install RET
To open the installed dotfile:
<SPC> f e d
To load some configuration layers using the variable
dotspacemacs-configuration-layers:
;; List of configuration layers to load.
dotspacemacs-configuration-layers '(auto-completion smex)
Some configuration layers support configuration variables to expose granular
control over layer-specific features, git layer being one such example.
Variables can be directly set within dotspacemacs-configuration-layers like so:
;; List of configuration layers to load.
dotspacemacs-configuration-layers '(auto-completion
(git :variables
git-magit-status-fullscreen t)
smex)
At anytime you can apply the changes made to the dotfile or layers
without restarting Spacemacs by pressing SPC f e R.
The dotfile template contain further information about how to customize Spacemacs. See the dotfile configuration section of the documentation for more details.
Dotdirectory (~/.spacemacs.d)
Like Emacs, Spacemacs initialization can also be contained in an init.el file
in a special directory ~/.spacemacs.d. The contents of the dotfile should be
then copied in the init.el file.
Learning Spacemacs
Editing Styles
Spacemacs can be used by Vim users or Emacs users by setting the
dotspacemacs-editing-style variable to vim, emacs or even hybrid
in the dotfile ~/.spacemacs.
The leader keys
Spacemacs key bindings use a leader key which is by default bound to
SPC (space bar) in vim or hybrid editing styles and M-m in emacs
style.
You can change it by setting the variable dotspacemacs-leader-key if
you use the vim style or dotspacemacs-emacs-leader-key if you use
the emacs style (these variables must be set in the file ~/.spacemacs).
For simplicity the documentation always refers to the leader key as
SPC.
There is secondary leader key called the major-mode leader key which is
set to , by default. This key is a shortcut for SPC m
where all the major-mode specific commands are bound.
Evil-tutor
If you are willing to learn the Vim key bindings (highly recommended since
you can benefit from them even in emacs style), press SPC h T
to begin an Evil-adapted Vimtutor.
Universal argument
In vim editing style the universal argument defaults to SPC u
instead of C-u because the latter is used to scroll up as in Vim.
Configuration layers and Package discovery
By using helm-spacemacs-help with SPC h SPC you can quickly search
for a package and get the name of the layers using it.
You can also easily go to the README.org of a layer or go to the initialization
function of a package.
Key bindings discovery
Thanks to which-key, whenever a prefix command is pressed (like SPC)
a buffer appears after one second listing the possible keys for this prefix.
It is also possible to search for specific key bindings by pressing:
SPC ?
To narrow the bindings list to those prefixed with SPC,
type a pattern like this regular expression:
SPC\ b
which would list all buffer related bindings. Note: You are at the
HELM-Descbind prompt, the pattern consists of 6 letters: uppercase SPC, a
backslash, an actual space and a lowercase b.
Describe functions
Describe functions are powerful Emacs introspection commands to get information
about functions, variables, modes etc. These commands are bound thusly:
| Key Binding | Description |
|---|---|
SPC h d f |
describe-function |
SPC h d k |
describe-key |
SPC h d m |
describe-mode |
SPC h d v |
describe-variable |
