Core Pillars
Four core pillars: Mnemonic, Discoverable, Consistent and "Crowd-Configured".
If any of these core pillars are violated, open an issue and we'll try our best to fix it.
Mnemonic
Key bindings are organized using mnemonic prefixes like b
for buffer, p
for
project, s
for search, h
for help, etc…
Discoverable
Innovative real-time display of available key bindings. Simple query system to quickly find available layers, packages, and more.
Consistent
Similar functionalities have the same key binding everywhere, thanks to a clearly defined set of conventions. Documentation is mandatory for any layer that ships with Spacemacs.
Crowd-Configured
Community-driven configuration provides curated packages tuned by power users and bugs are fixed quickly.
Highlighted features
- Bring the efficiency of modal editing to the powerful Emacs lisp platform. Modal UX is optional and Spacemacs can be used with only Emacs key bindings.
- Integrate nicely with
Evil
states (Vim
modes). - Keep your fingers on the home row for quicker editing with support for QWERTY and BEPO layouts.
- Minimalistic and nice graphical UI keeps your available screen space for what matters: your text files.
- Fast boot time: packages and configuration are lazy-loaded as much as possible. For even faster boot time, Spacemacs now provides full support for the new portable dumper available in Emacs 27 and later.
- Lower the risk of RSI by heavily using the space bar instead of modifiers. If you have issues with your thumbs you can still use Spacemacs using modifiers.
- Contribute easily with your improvements and new configuration layers.
- Very active and helpful community on
Gitter
andIRC
(via Gitter IRC bridge)
Screenshots
Python
Note: Even though screenshots are updated frequently, Spacemacs is evolving quickly and the screenshots may not reflect exactly the current state of the project.
Who can benefit from this?
- Spacemacs was initially intended to be used by Vim users who want to go to
the next level by using Emacs (see guide for Vimmers). But it is now
perfectly usable by non Vim users by choosing the
emacs
editing style. - It is also a good fit for people wanting to lower the risk of RSI induced by
the default Emacs key bindings. (This is an assumption, there are no official
studies to prove this!) If you have issues using your thumbs you can still
use the
emacs
editing style which puts the leader key on a modifier combination. - Emacs users wanting to learn a different way to edit files or wanting to
learn Vim key bindings or even wanting to mix both editing styles by setting
their style to
hybrid
. - Emacs users wanting a simple but deep configuration system that greatly lowers the risk of .emacs bankruptcy.
- Pair-programming users thanks to out of the box support for dynamic switching of editing style. A Vim user and an Emacs user can use the same Spacemacs comfortably.
Update and Rollback
Update Spacemacs repository
There are several methods of updating the core files and layer information for Spacemacs. It is recommended to update the packages first; see the next section.
Automatic Updates
Spacemacs will automatically check for a new version periodically. When it detects that a new version is available an arrow will appear in the modeline. Click it to update Spacemacs. You must restart Emacs after updating. Update Button
Note: If you use the develop
branch of Spacemacs, automatic update is
disabled—you have to update manually using git.
Updating from the Spacemacs Buffer
Use the button labeled "Update Spacemacs" in the Spacemacs buffer. You will be prompted for the version you would like to use.
Note: If you use the develop
branch of Spacemacs, you cannot use this method.
Updating Manually with git
To update manually close Emacs and update the git repository:
$ git pull origin master
Note: The master branch is considered to be immutable in the sense that you must not modify it by adding your own commit. If you do so you will break the automatic update of Spacemacs on the master branch. To fork Spacemacs code you have to use a custom branch that you manage manually.
Update packages
To update the Emacs packages used by Spacemacs press RET (enter) or click on the
link [Update Packages]
in the startup page under the banner then restart
Emacs. If you prefer, you can use the command
configuration-layer/update-packages
instead of the button.
If anything goes wrong you should be able to rollback the update by pressing
RET
or clicking on the [Rollback Package Update]
link in the startup page
and choosing a rollback slot (sorted by date). This button uses the command
configuration-layer/rollback
.
Configuration layers
This section is an overview of layers. A more extensive introduction to writing configuration layers can be found here (recommended reading!).
Purpose
Layers help collect related packages together to provide features. For example,
the python
layer provides auto-completion, syntax checking, and REPL support
for python files. This approach helps keep configuration organized and reduces
overhead for the user by keeping them from having to think about what packages
to install. To install all the python
features the user has just to add the
python
layer to their dotfile.
Structure
Configuration is organized in layers. Each layer has the following structure:
[layer_name] |__ [local] | |__ [package 1] | | ... | |__ [package n] |-- layers.el |__ packages.el |__ funcs.el |__ config.el |__ keybindings.el [] = directory
Where:
File | Usage |
---|---|
layers.el | The place to declare additional layers |
packages.el | The list of packages and their configuration functions (init, post-init, etc…) |
funcs.el | All functions defined in the layer (used in package configuration for instance) |
config.el | Layer configuration (defines the layer variables default values and setup some config variables) |
keybindings.el | General key bindings not tied to a specific package configuration |
Packages
can be:
ELPA
packages installed from anELPA
compliant repository- local packages in a layer's
local
folder - installed from an online source using quelpa.
Configure packages
With a layer
Declaration
Packages
are declared in a variable called <layer>-packages
where <layer>
is the name of the layer.
Example:
(setq <layer>-packages '(package1 package2 ...)
All packages from all layers are processed in alphabetical order so sometimes
you'll have to use some with-eval-after-load
black magic to configure them
properly. For instance, if package A
depends on B
then you can configure
A
with:
(with-eval-after-load 'B ...)
For details on installing packages using quelpa or local packages see LAYERS.
Initialization
To initialize a package xxx
, define a function with this format in
packages.el
:
(defun <layer>/init-xxx () ...body )
It is common to define the body with the use-package macro.
Exclusion
It is possible to exclude some packages from Spacemacs on a per-layer basis. This is useful when a configuration layer aims to replace a stock package declared in the Spacemacs layer.
To do so add the package names to exclude to the variable
<layer>-excluded-packages
.
Example:
(setq <layer>-excluded-packages '(package1 package2 ...)
Without a layer
Sometimes a layer can be an unnecessary overhead, this is the case if you just want to install a package with very few configuration associated to it. A good example is some niche language where you are only interested in syntax highlighting.
You can install such packages by adding them to the variable
dotspacemacs-additional-packages
under the dotspacemacs/layers
function in your dotfile.
For example, to install llvm-mode
and dts-mode
:
(defun dotspacemacs/layers ()
"Configuration Layers declaration..."
(setq-default
;; ...
dotspacemacs-additional-packages '(llvm-mode dts-mode)
;; ...
))
If you want to add some configuration for them, do so in the
dotspacemacs/user-config
function, or consider creating a layer.
Packages synchronization
Spacemacs will only install the packages that are explicitly used by the user.
A package is considered to be used if its layer is used (i.e. listed in
dotspacemacs-configuration-layers
).
Any package that is not used will be considered an orphan and will be deleted at
the next startup of Emacs.
Types of configuration layers
There are two types of configuration layers:
- distributed layers (in the
layers
directory, those layers are contributions shared by the community and merged upstream) - private (in the
private
directory, they are ignored by Git)
Submitting a configuration layer upstream
If you decide to provide a configuration layer, please check the contribution guidelines first in CONTRIBUTING.
Example: Themes Megapack example
This is a simple configuration layer listing a bunch of themes which you can find here.
To install it, just add themes-megapack
to your ~/.spacemacs
like so:
(setq-default dotspacemacs-configuration-layers '(themes-megapack))
Adding this layer will install around 100 themes; to uninstall them remove the
layer from the dotspacemacs-configuration-layers
and press SPC f e R
.
Managing private configuration layers
Spacemacs's configuration system is flexible enough to let you manage your private layers in different ways.
Using the private directory
Everything in the private directory is ignored by Git so it is a good place to store private layers. There is a huge drawback to this approach though: your layers are not source controlled.
Using an external Git repository
This is the recommended way to manage your private layers.
The best approach is to store all your private layers in an external Git
repository. For example, if you have a dotfiles
repository it is a good
practice to store these layers in there, along with your ~/.spacemacs
file.
Then you are free to symlink your layers into ~/emacs.d/private
or leave them
anywhere you want, and reference the parent directory in the variable
dotspacemacs-configuration-layer-path
of your ~/.spacemacs
.
Note: You could also have a dedicated repository for all your private layers
and then directly clone this repository in ~/.emacs.d/private
.
Using a personal branch
The final main way to manage your private layers is to push them in a personal
branch that you keep up to date with upstream master
or develop
.
Tips for writing layers
Please refer to this introduction for some tips on writing layers, and how to best make them fit with the Spacemacs philosophy and loading strategy.
Dotfile Configuration
User configuration can be stored in your ~/.spacemacs
file.
Dotfile Installation
The very first time Spacemacs starts up, it will ask you several questions
and then install the .spacemacs
file in your HOME
directory.
Alternative dotdirectory
A dotdirectory ~/.spacemacs.d/
can be used instead of a dotfile.
If you want to use this option, move ~/.spacemacs
to ~/.spacemacs.d/init.el
.
It is also possible to override the location of ~/.spacemacs.d/
using the
environment variable SPACEMACSDIR
. Of course, you can also use symlinks to
change the location of this directory.
Note: ~/.spacemacs
will always take priority over ~/.spacemacs.d/init.el
,
so ~/.spacemacs
must not exist for ~/.spacemacs.d/init.el
to be used by
Spacemacs.
Synchronization of dotfile changes
To apply the modifications made in ~/.spacemacs
press SPC f e R
. It will
re-execute the Spacemacs initialization process.
Note: A synchronization re-executes the functions dotspacemacs/init
,
dotspacemacs/user-init
and dotspacemacs/user-config
.
Depending on the contents of these functions, you may encounter some unwanted side
effects. For instance, if you use a toggle in dotspacemac/user-config
to enable
some behavior, this behavior will be turned off whenever the dotfile is
re-synchronized. To avoid these side-effects, it is recommended to either use
setq
expressions instead of toggle functions, or to use the on
or off
versions instead (i.e. instead of spacemacs/toggle-<thing>
, use
spacemacs/toggle-<thing>-on
or spacemacs/toggle-<thing>-off
).
It is possible to skip the execution of dotspacemacs/user-config
with the
universal argument (SPC u SPC f e R
).
Testing the dotfile
You can use the command SPC SPC dotspacemacs/test-dotfile
to check if your
~/.spacemacs
looks correct. This will check, among other things, whether the
declared layers can be found and that the variables have sensible values. These
tests are also run automatically when you synchronize with SPC f e R
.
Dotfile Contents
Configuration functions
Five special functions in the ~/.spacemacs
file can be used to perform
configuration at the beginning and end of Spacemacs loading process:
dotspacemacs/init
is called at the very startup of Spacemacs initialization before layers configuration. You should not put any user code in there besides modifying the Spacemacs variable values prefixed withdotspacemacs-
.dotspacemacs/user-init
is called immediately afterdotspacemacs/init
, before layer configuration. This function is mostly useful for variables that need to be set before packages are loaded.dotspacemacs/user-env
is called before the layers and packages configuration and it is responsible to setup environment variables.dotspacemacs/layers
is called at the startup of Spacemacs initialization, this is where you set the Spacemacs distribution and declare layers to be used in your configuration. You can also add or exclude packages of your choice and tweak some behaviors of Spacemacs loading.dotspacemacs/user-config
is called at the very end of Spacemacs initialization after layers configuration. This is the place where most of your configurations should be done. Unless it is explicitly specified that a variable should be set before a package is loaded, you should place your code here.dotspacemacs/emacs-custom-settings
is a generated function where all Emacs custom settings are written. You should not edit this function. SeeCustom variables
section for more information.
Custom variables
By default custom variables from M-x customize-group
are automatically saved
at the end of your ~/.spacemacs
file in the function
dotspacemacs/emacs-custom-settings
unless you declare a custom custom-file
in the dotspacemacs/user-init
function, in this case custom variables will be
written to the user defined custom-file
and the function
dotspacemacs/emacs-custom-settings
will remain empty.
Note: If you set a custom custom-file
value then it is your responsibility
to load this file at the appropriate time. Often the best time to load it is
just after setting the value for custom-file
in the dotspacemacs/user-init
function.
Declaring Configuration layers
To use a configuration layer, declare it in your dotfile by adding it to the
dotspacemacs-configuration-layers
variable of your ~/.spacemacs
.
Note: In this documentation a used layer
is equivalent to a declared
layer
.
For instance, RMS can add his private configuration layer like this:
(setq-default dotspacemacs-configuration-layers
'(
;; other layers
;; rms layer added at the end of the list
rms
))
Official layers shipped with Spacemacs are stored in ~/.emacs.d/layers
. The
directory ~/.emacs.d/private
is a drop-in location for your private layers.
It is possible to put layers at the location of your choice provided you tell
Spacemacs where to look for them. This is done by setting the list
dotspacemacs-configuration-layer-path
in your ~/.spacemacs
. For instance
to add some layers in ~/.myconfig
, set the variable like this:
(setq-default dotspacemacs-configuration-layer-path '("~/.myconfig/"))
Setting configuration layers variables
Some configuration layers have configuration variables to enable specific
features. For instance the git layer has several configuration variables, they
can be set directly in the dotspacemacs-configuration-layers
like this:
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(auto-completion
(git :variables
git-magit-status-fullscreen t
git-variable-example nil)
smex)))
The :variables
keyword is a convenience to keep layer configuration close to
their declaration. Setting layer variables in the dotspacemacs/user-init
function of your dotfile is also a perfectly valid way to configure a layer.
Disabling layer services in other layers
Often layers enable services that other layers can use. For instance if you use
the layer auto-completion
then all other layers supporting auto-completion
will have this feature enabled.
Sometimes you may want to disable a service added by a layer in some specific
layers. Say you want to disable auto-completion
in org
and git
layers,
you can do it with the following layer declaration.
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(org git
(auto-completion :disabled-for org git))))
You can also use the :enabled-for
construct to disable it for all layers
except those explicitly identified.
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(java python c-c++
(auto-completion :enabled-for java python))))
Note that :enabled-for
may be an empty list.
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(java python c-c++
(auto-completion :enabled-for))))
:enabled-for
takes precedence over :disabled-for
if both are present.
Selecting/Ignoring packages of a layer
By default a declared layer installs/configures all its associated packages. You
may want to select only some of them or ignoring some of them. This is possible
with the :packages
keyword.
For instance to ignore the treemacs
and fancy-battery
packages from
spacemacs-ui-visual
layer:
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(auto-completion
(spacemacs-ui-visual :packages (not treemacs fancy-battery))))
The opposite would be to ignore all packages except treemacs
and
fancy-battery
:
(defun dotspacemacs/layers ()
;; List of configuration layers to load.
(setq-default dotspacemacs-configuration-layers
'(auto-completion
(spacemacs-ui-visual :packages treemacs fancy-battery)))
Note: Ignoring a package from a layer is different than excluding a package. An excluded packages is completely removed from your configuration whereas an ignored package is ignored only for a given layer but it can remain on your system. It happens that if the given layer is the owner of the package then ignoring this package is the same as excluding it (because the package becomes orphan so it is considered unused by Spacemacs).
Excluding packages
You can exclude packages you don't want to install with the variable
dotspacemacs-excluded-packages
(see Configuration layers for more info
on packages).
For instance, to disable the rainbow-delimiters
package:
(setq-default dotspacemacs-excluded-packages '(rainbow-delimiters))
When you exclude a package, Spacemacs will automatically delete it for you the next time you launch Emacs or at the next dotfile synchronization. All the orphan dependencies are also deleted automatically. Excluding a package effectively remove all references to it in Spacemacs without breaking the rest of the configuration, this is a powerful feature which allows you to quickly remove any feature from Spacemacs.
Note: A few packages are essential for Spacemacs to correctly operate, those
packages are protected and cannot be excluded or uninstalled even if they become
orphans or are excluded. use-package
is an example of a protected package that
cannot be removed from Spacemacs.
Concepts
Editing Styles
Spacemacs comes with several editing styles which can be switched dynamically providing an easier way to do pair programming, for instance between a Vim user and an Emacs user.
Three styles are available:
- Vim,
- Emacs,
- Hybrid (a mix between Vim and Emacs).
To set the editing style set the variable dotspacemacs-editing-style
to
either vim
, hybrid
, or emacs
. It possible to pass a list of variables
as well with the keyword :variables
, just like for layer variables.
Vim
Spacemacs behaves like in Vim using the Evil mode package to emulate Vim key
bindings. This is the default style of Spacemacs; it can be set explicitly by
setting the dotspacemacs-editing-style
variable to vim
in the dotfile.
To bind keys in Vim editing style (insert state
):
(define-key evil-insert-state-map (kbd "C-]") 'forward-char)
When setting the Vim style you can pass any variable supported by evil-mode
with the keyword :variables
. Spacemacs also supports the following editing
style variables for Vim:
Variables | Description |
---|---|
vim-style-visual-feedback |
If non-nil then objects are briefly highlighted |
vim-style-remap-Y-to-y$ |
If non-nil Y is remapped to y$ in Evil states |
vim-style-retain-visual-state-on-shift |
If non-nil, the shift mappings < and > retain visual state |
vim-style-visual-line-move-text |
If non-nil, J and K move lines up and down when in visual mode |
vim-style-ex-substitute-global |
If non-nil, inverse the meaning of g in :substitute Evil ex-command |
Default configuration is:
(setq-default dotspacemacs-editing-style '(vim :variables
vim-style-visual-feedback nil
vim-style-remap-Y-to-y$ nil
vim-style-retain-visual-state-on-shift t
vim-style-visual-line-move-text nil
vim-style-ex-substitute-global nil)
Emacs
Spacemacs behaves like in raw Emacs using the Holy mode which configures Evil to
make the emacs state
the default state everywhere.
Set the dotspacemacs-editing-style
variable to emacs
in the dotfile.
In Emacs style the leader is available on M-m
. It is possible to toggle it on
and off with SPC t E e
and M-m t E e
. When off the vim
style is enabled.
To bind keys in Emacs editing style (emacs state
):
(define-key evil-emacs-state-map (kbd "C-]") 'forward-char)
Hybrid
The hybrid editing style is like the Vim style except that insert state
is
replaced by a new state called hybrid state
. In hybrid state
all the Emacs
key bindings are available; this is like replacing the insert state
with the
emacs state
but provides an isolated key map evil-hybrid-state-map
.
To bind keys in Hybrid editing style (hybrid state
):
(define-key evil-hybrid-state-map (kbd "C-]") 'forward-char)
This style can be tweaked to be more like Emacs or more like Vim depending on the user preferences. The following variables are available to change the style configuration:
Variables | Description |
---|---|
hybrid-style-visual-feedback |
If non-nil then objects are briefly highlighted |
hybrid-style-default-state |
The default state when opening a new buffer. Set it to emacs for a more emacsy style |
hybrid-style-enable-hjkl-bindings |
If non-nil then packages will configure h j k l key bindings for navigation |
hybrid-style-enable-evilified-state |
If non-nil buffer are evilified when supported, if nil then emacs state is enabled |
hybrid-style-use-evil-search-module |
If non-nil then use evil own search module which is closer to Vim search behavior |
Default configuration is:
(setq-default dotspacemacs-editing-style '(hybrid :variables
hybrid-style-visual-feedback nil
hybrid-style-enable-evilified-state t
hybrid-style-enable-hjkl-bindings nil
hybrid-style-use-evil-search-module nil
hybrid-style-default-state 'normal)
To toggle the hybrid style on and off use SPC t E h
and M-m t E h
. When
off the vim
style is enabled.
States
Spacemacs has 10 states:
State | Default Color | Description |
---|---|---|
normal | orange | like the normal mode of Vim , used to execute and combine commands |
insert | green | like the insert mode of Vim , used to actually insert text |
visual | gray | like the visual mode of Vim , used to make text selection |
motion | purple | exclusive to Evil , used to navigate read only buffers |
emacs | blue | exclusive to Evil , using this state is like using a regular Emacs without Vim |
replace | chocolate | like replace mode of Vim , overwrites the character under point instead of inserting a new one |
hybrid | blue | exclusive to Spacemacs, this is like the insert state except that all the emacs key bindings are available |
evilified | light brown | exclusive to Spacemacs, this is an emacs state modified to bring Vim navigation, selection and search. |
lisp | pink | exclusive to Spacemacs, used to navigate Lisp code and modify it (more info) |
iedit | red | exclusive to Spacemacs, used to navigate between multiple regions of text using iedit (more info) |
iedit-insert | red | exclusive to Spacemacs, used to replace multiple regions of text using iedit (more info) |
Note: Technically speaking there is also the operator
evil state.
Evilified modes
Some buffers are not for editing text and provide their own key bindings for
certain operations. These often conflict with Vim bindings. To make such buffers
behave more like Vim in a consistent manner, they use a special state called
evilified state. In evilified state, a handful of keys work as in Evil, namely
/
, :
, h
, j
, k
, l
, n
, N
, v
, V
, gg
, G
, C-f
, C-b
,
C-d
, C-e
, C-u
, C-y
and C-z
. All other keys work as intended by the
underlying mode.
Shadowed keys are moved according to the pattern: a
→ A
→ C-a
→ C-A
For example, if the mode binds a function to n
, that is found under C-n
in
evilified state, since both n
and N
are reserved, but C-n
is not. On the
other hand, anything originally bound to k
will be found on K
, since k
is
reserved but K
is not. If there is a binding on K
, that will be moved to
C-k
.
In addition to this, C-g
, being an important escape key in Emacs, is skipped.
So anything bound to g
originally will be found on C-G
, since g
, G
and
C-g
are all reserved.
Evil leader
Spacemacs uses a leader key to bind almost all its key bindings.
This leader key is commonly set to ,
by Vim users. In Spacemacs the leader
key is set on SPC
(the space bar, hence the name spacemacs
). This key is the
most accessible key on a keyboard and it is pressed with the thumb which is a
good choice to lower the risk of RSI. It can be customized to any other key
using the variable dotspacemacs-leader-key
and dotspacemacs-emacs-leader-key
.
With Spacemacs there is no need to remap your keyboard modifiers to attempt
to reduce the risk of RSI, every command can be executed very easily while you
are in normal
mode by pressing the SPC
leader key, here are a few examples:
- Save a buffer:
SPC f s
- Save all opened buffers:
SPC f S
- Open (switch) to a buffer:
SPC b b
Universal argument
The universal argument C-u
is an important command in Emacs but it is also a
very handy Vim key binding to scroll up.
Spacemacs binds C-u
to scroll-up
and changes the universal argument binding
to SPC u
.
Transient-states
Spacemacs defines a wide variety of transient states
(temporary overlay maps)
where it makes sense. This prevents one from doing repetitive and tedious
presses on the SPC
key.
When a transient state
is active, documentation is displayed in the
minibuffer. Additional information may also be displayed in the minibuffer.
Auto-highlight-symbol transient state: Text scale transient state:
Toggles
Spacemacs tries to unify the interface to handle toggles using a custom macro
called spacemacs|add-toggle
.
There exists two type of toggles:
- globally available toggles under the key prefixes
SPC t
andSPC T
- major mode specific toggles under the key prefix
SPC m T
When a toggle is turned on a unicode symbol is displayed in the mode-line, this symbol is a circled letter for globally available toggles and a plain squared letter for major mode specific toggles. The letter corresponds to the key binding for this toggle.
For instance the globally available toggle for which-key
is under SPC t K
and its corresponding symbol in the mode-line is Ⓚ
. Also the major mode
specific toggle for nameless
available only in emacs-lisp
mode is under
SPC m T n
and its corresponding symbol in the mode-line is 🅽
.
All toggles can be browsed via the Spacemacs help system under SPC h t
.
Configuring toggles in the dotfile
To set the toggle states to your preference you can use a set of functions
that should be called in your dotspacemacs/user-config
function of your
dotfile.
Globally available toggles can be turned on and off using the functions
spacemacs/toggle-NAME-on
and spacemacs/toggle-NAME-off
respectively.
NAME
corresponds to the name of the toggle, for instance which-key
for the toggle to turn on and off the which-key
minor mode.
(spacemacs/toggle-which-key-on)
Major mode specific toggles can be turned on by registering a hook on them to
call the "toggle on" function automatically whenever a buffer using this major
mode is opened. It can be done convenienty using the function
spacemacs/toggle-NAME-on-register-hooks
. It also exists variants of this
function for each supported major mode like
spacemacs/toggle-NAME-on-register-hook-MODE
.
(spacemacs/toggle-nameless-on-register-hooks)
;; or to enable it for emacs-lips buffers only
(spacemacs/toggle-nameless-on-register-hook-emacs-lisp-mode)
Differences between Vim, Evil and Spacemacs
- The
,
key does repeat lastf
,t
,F
, orT
command in opposite direction inVim
, but in Spacemacs it is the major mode specific leader key by default (which can be set on another key binding in the dotfile).
Send a PR to add the differences you found in this section.
The vim-surround case
There is one obvious visible difference though. It is not between Evil
and
Vim
but between Spacemacs and vim-surround: in visual mode the surround
command is on S
in vim-surround
whereas it is on s
in Spacemacs.
This is something that can surprise some Vim users so here are some motivations behind this change:
s
andc
do the same thing invisual state
,s
is only useful to delete one character and add more than one character which is a very narrow use casec
accept motions and can do everythings
can do innormal state
(note that this is also true forr
butr
is more useful because it stays innormal state
)surround
command is just a more powerful command thans
.
If you are not convinced, then here is the snippet to revert back to the default
Vim + vim-surround
setup (add it to your dotspacemacs/user-config
):
(evil-define-key 'visual evil-surround-mode-map "s" 'evil-substitute)
(evil-define-key 'visual evil-surround-mode-map "S" 'evil-surround-region)
Evil plugins
Spacemacs ships with the following evil plugins:
Mode | Description |
---|---|
evil-args | motions and text objects for arguments |
evil-exchange | port of vim-exchange |
evil-indent-textobject | add text object based on indentation level |
evil-matchit | port of matchit.vim |
evil-nerd-commenter | port of nerdcommenter |
evil-numbers | like C-a and C-x in vim |
evil-search-highlight-persist | emulation of hlsearch behavior |
evil-surround | port of vim-surround |
evil-visualstar | search for current selection with * |
Treemacs | a file explorer like NERD Tree |
Environment variables and PATH
Environment variables are handled by the function dotspacemacs/user-env
of
your dotfile.
Default behavior
By default, the function dotspacemacs/user-env
only calls the function
spacemacs/load-spacemacs-env
which loads the environment variables from
the file ~/.spacemacs.env
. This file is automatically created for you by
Spacemacs and it is initialized with the environment variables of your
system as well as the environment variables of your default shell.
To open this file use SPC f e e
. You can edit it to change or add/remove
environment variables. Use SPC f e E
to reload it.
Some dynamic environment variables are ignored by Spacemacs when it first
creates the ~/.spacemacs.env
file. These ignored variables are listed in
the variable spacemacs-ignored-environment-variables
.
It is possible to force a new import of system and shell environment variables
with SPC f e C-e
. Note that this action will overwrite ~/.spacemacs.env
.
Managing environment variables by yourself
For full flexibility you can bypass the default behavior simply by removing
the call to spacemacs/load-spacemacs-env
from your dotspacemacs/user-env
function.
From there you can choose to use the popular package exec-path-from-shell
or just call built-in functions like setenv
or (add-to-list 'exec-path ...)
.
If you choose to handle the environment variables by yourself then SPC f e e
will go to the function dotspacemacs/user-env
instead of opening the file
~/.spacemacs.env
. In all cases SPC f e E
calls the function
dotspacemacs/user-env
so you can update your variables in place.
Note about the function dotspacemacs/user-env
It's possible that you don't have this function defined if you have an older
dotfile. It is recommended to update your dotfile by adding this function,
see the file ~/.emacs.d/core/template/.spacemacs.template
to copy it.
If you don't create such function then Spacemacs assumes you are using the
default behavior described above.
Binding keys
To be compatible with all Spacemacs bindings, please refer to Conventions.
In brief, SPC o
is reserved for user custom bindings in global-map
,
and SPC m o
in major modes.
Key sequences are bound to commands in Emacs in various keymaps. The most basic
map is the global-map
. Setting a key binding in the global-map
is achieved
with the function global-set-key
. Example to bind a key to the command
forward-char
:
(global-set-key (kbd "C-]") 'forward-char)
The kbd
macro accepts a string describing a key sequence. The global-map
is
often shadowed by other maps. For example, evil-mode
defines keymaps that
target states (or modes in vim terminology). Here is an example that creates the
same binding as above but only in insert state
(define-key
is a built-in
function. Evil-mode
has its own functions for defining keys).
(define-key evil-insert-state-map (kbd "C-]") 'forward-char)
Perhaps most importantly for Spacemacs is the use of the bind-map package to
bind keys behind a leader key.
This is where most of the Spacemacs bindings live. Binding keys behind the
leader key is achieved with the functions spacemacs/set-leader-keys
and
spacemacs/set-leader-keys-for-major-mode
, example:
(spacemacs/set-leader-keys "C-]" 'forward-char)
(spacemacs/set-leader-keys-for-major-mode 'emacs-lisp-mode "C-]" 'forward-char)
These functions use a macro like kbd
to translate the key sequences for you.
The second function, spacemacs/set-leader-keys-for-major-mode
, binds the key
only in the specified mode. The second key binding is active only when the
major mode is emacs-lisp
.
Finally, one should be aware of prefix keys. Essentially, all keymaps can be
nested. Nested keymaps are used extensively in spacemacs, and in vanilla Emacs
for that matter. For example, SPC a
points to key bindings for "applications",
like SPC a c
for calc-dispatch
. Nesting bindings is easy.
(spacemacs/declare-prefix "o" "custom")
(spacemacs/set-leader-keys "oc" 'my-custom-command)
The first line declares SPC o
to be a prefix and the second binds the key
sequence SPC oc
to the corresponding command. The first line is actually
unnecessary to create the prefix, but it will give your new prefix a name that
key-discovery tools can use (e.g., which-key).
Example to create binding in major mode:
(spacemacs/declare-prefix-for-mode 'org-mode "o" "custom")
(spacemacs/set-leader-keys-for-major-mode 'org-mode "oi" 'org-id-get-create)
This would add binding as , oi
and SPC moi
.
There is much more to say about bindings keys, but these are the basics. Keys
can be bound in your ~/.spacemacs
file or in individual layers.
GUI Elements
Spacemacs has a minimalistic and distraction free graphical UI:
- custom powerline mode-line with color feedback according to current Flycheck status
- Unicode symbols for minor mode lighters which appear in the mode-line
- custom fringe bitmaps and error feedbacks for Flycheck
Color themes
Default theme
The official Spacemacs theme is spacemacs-dark and it is the default theme
installed when you first started Spacemacs. There are two variants of the
theme, a dark one and a light one. Some aspects of these themes can be customized
in the function dotspacemacs/user-init
of your ~/.spacemacs
:
- the comment background with the boolean
spacemacs-theme-comment-bg
- the height of org section titles with
spacemacs-theme-org-height
Choosing themes
It is possible to define your default themes in your ~/.spacemacs
with the
variable dotspacemacs-themes
. For instance, to specify spacemacs-light
,
leuven
and zenburn
:
(setq-default dotspacemacs-themes '(spacemacs-light leuven zenburn))
dotspacemacs-themes
entries accept the same properties as packages listed
in layers package lists or in dotspacemacs-additional-packages
. So it is
possible to fetch a package from a specific location. For example, you could
fetch zenburn
theme directly from the GitHub repository with the following
declaration:
(setq-default dotspacemacs-themes
'(spacemacs-light
leuven
(zenburn :location (recipe :fetcher github
:repo "bbatsov/zenburn-emacs"))
))
Important note: If you use :location local
then you have to put your theme
in the directory private/local/<theme-package-name>/
with theme-package-name
being the name of your package suffixed with -theme
as mentioned in the Emacs
conventions.
For instance if your theme is foo
then you have to put our theme
files in the directory private/local/foo-theme
.
You can cycle between the themes declared in dotspacemacs-themes
with
SPC T n
and select an installed theme with SPC T s
.
Themes Transient State
Key binding | Description |
---|---|
n or <right> |
change to the next theme |
p or <left> |
change to the previous theme |
t or <up> |
open helm-themes to select an installed theme |
Browsing themes
You can see samples of all themes included in the themes-megapack
layer
in this theme gallery from Rob Merrell.
Notes
- You don't need to explicitly list in a layer the theme packages you are
defining in
dotspacemacs-themes
, Spacemacs is smart enough to remove those packages from the list of orphans. - Due to the inner working of themes in Emacs, switching theme during the same session may have some weird side effects. Although these side effects should be pretty rare.
- In the terminal version of Emacs, color themes will not render correctly as colors are rendered by the terminal and not by emacs. You will probably have to change your terminal color palette. More explanations can be found on emacs-color-theme-solarized webpage.
Font
The default font used by Spacemacs is Source Code Pro by Adobe. It is recommended to install it on your system if you wish to use it.
To change the default font set the variable dotspacemacs-default-font
in your
.spacemacs
file. By default its value is:
(setq-default dotspacemacs-default-font '("Source Code Pro"
:size 10.0
:weight normal
:width normal))
If the specified font is not found, the fallback one will be used (depends on your system). Also note that changing this value has no effect if you are running Emacs in terminal.
The properties should be pretty straightforward, it is possible to set any valid property of a font-spec:
:family
Font family or fontset (a string).-
:width
Relative character width. This should be one of the symbols:- ultra-condensed
- extra-condensed
- condensed
- semi-condensed
- normal
- semi-expanded
- expanded
- extra-expanded
- ultra-expanded
:height
The height of the font. In the simplest case, this is an integer in units of 1/10 point.-
:weight
Font weight- one of the symbols (from densest to faintest):- ultra-bold
- extra-bold
- bold
- semi-bold
- normal
- semi-light
- light
- extra-light
- ultra-light
-
:slant
Font slant- one of the symbols:- italic
- oblique
- normal
- reverse-italic
- reverse-oblique
:size
The font size- either a non-negative integer that specifies the pixel size, or a floating-point number that specifies the point size.:adstyle
Additional typographic style information for the font, such as 'sans'. The value should be a string or a symbol.:registry
The charset registry and encoding of the font, such as 'iso8859-1'. The value should be a string or a symbol.:script
The script that the font must support (a symbol).
GUI Toggles
Some graphical UI indicators can be toggled on and off (toggles start with t
and T
):
Key binding | Description |
---|---|
SPC t 8 |
highlight any character past the 80th column |
SPC t f |

SPC t h h |
toggle highlight of the current line |
SPC t h i |
toggle highlight indentation levels |
SPC t h c |
toggle highlight indentation current column |
SPC t h s |
toggle syntax highlighting |
SPC t i |
toggle indentation guide at point |
SPC t l |

SPC t L |
toggle visual lines |
SPC t n |
toggle line numbers |
SPC t r |
toggle relative line numbers |
SPC t v |
toggle smooth scrolling |
SPC t V |

SPC T f |
toggle display of the fringe |
SPC T m |
toggle menu bar |
SPC T M |

toggle tool bar |
SPC T T |
toggle frame transparency and enter transparency transient state |
Note: These toggles are all available via the spacemacs-help
interfaces
(press SPC h SPC
to display the spacemacs-help
buffer).
Global line numbers
Line numbers can be toggled on in all prog-mode
and text-mode
buffers by
setting the dotspacemacs-line-numbers
variable in your ~/.spacemacs
to t
.
(setq-default dotspacemacs-line-numbers t)
If it is set to relative
, line numbers are show in a relative way:
(setq-default dotspacemacs-line-numbers 'relative)
If it is set to visual
, line numbers are shown in a relative way, but wrapped
lines will be treated as multiple lines:
(setq-default dotspacemacs-line-numbers 'visual)
dotspacemacs-line-numbers
can also be set to a property list for finer control
over line numbers activation.
Available properties:
Property | Description |
---|---|
:disabled-for-modes |
list of major modes where line numbering is inhibited |
:enabled-for-modes |
disable for all major modes except those listed. Takes precedence over :disabled-for-modes |
:relative |
if non-nil, line numbers are relative to the position of the cursor |
:visual |
if non-nil, line numbers are relative to the position of the cursor, but lines are separated by visual state - a wrapped line, for example, will be treated as more than one line. When set to t, this option takes precedence over :relative |
:size-limit-kb |
size limit in kilobytes after which line numbers are not activated |
Note that if :enabled-for-modes
is nil
or not specified, then the default is
to enable line numbers in any prog-mode
and text-mode
that wasn't explicitly
disabled via :disabled-for-modes
. To enable line numbers in a major mode that
doesn't derive from prog-mode
or text-mode
, you must specify it directly in
:enabled-for-modes
. To enable line numbers even in non-prog-mode and
non-text-mode buffers, set :enabled-for-modes
to all
.
Examples:
Disable line numbers in dired-mode, doc-view-mode, markdown-mode, org-mode, pdf-view-mode, text-mode as well as buffers over 1Mb:
(setq-default dotspacemacs-line-numbers '(:relative nil
:disabled-for-modes dired-mode
doc-view-mode
markdown-mode
org-mode
pdf-view-mode
text-mode
:size-limit-kb 1000))
Enable relative line numbers only in c-mode and c++ mode with a size limit of dotspacemacs-large-file-size
:
(setq-default dotspacemacs-line-numbers '(:relative t
:enabled-for-modes c-mode
c++-mode
:size-limit-kb (* dotspacemacs-large-file-size 1000))
Enable line numbers everywhere, except for buffers over 1Mb:
(setq-default dotspacemacs-line-numbers '(:relative nil
:size-limit-kb 1000))
Enable line numbers only in programming modes, except for c-mode and c++ mode:
(setq-default dotspacemacs-line-numbers '(:relative nil
:enabled-for-modes prog-mode
:disabled-for-modes c-mode c++-mode
:size-limit-kb (* dotspacemacs-large-file-size 1000))
Enable line numbers everywhere, even in non-prog-mode and non-text-mode buffers:
(setq-default dotspacemacs-line-numbers '(:enabled-for-modes 'all))
Mode-line
Mode-line themes
Spacemacs supports different mode-line themes. The mode-line theme is set in the
dotfile with the variable dotspacemacs-mode-line-theme
.
Currently supported themes are:
- spaceline themes:
spacemacs
,all-the-icons
,custom
- a powerline theme:
vim-powerline
- no theme at all:
vanilla
The default theme is spacemacs
and this theme is described in more detailed in
the next section.
all-the-icons
is the theme defined in the package spaceline-all-the-icons.
custom
is a user custom spaceline theme, see the guide in the following section.
vim-powerline
is for the Vim users who are nostalgic of the good old Vim
powerline.
vanilla
is the stock mode-line that comes with Emacs.
Separators
For spacemacs
, all-the-icons
and custom
themes you can specify the type
of separator you want with the property :separator
.
(setq dotspacemacs-mode-line-theme '(all-the-icons :separator slant))
Supported separators and preview:
Separator | Spacemacs | All-the-icons | Screenshot |
---|---|---|---|
alternate |
X | ||
arrow |
X | X | |
arrow-fade |
X | ||
bar |
X | ||
box |
X | ||
brace |
X | ||
butt |
X | ||
chamfer |
X | ||
contour |
X | ||
cup |
X | ||
curve |
X | ||
rounded |
X | ||
roundstub |
X | ||
slant |
X | X | |
wave |
X | X | |
zigzag |
X | ||
nil |
X | ||
none |
X |
A last special separator is supported, it is utf-8
which uses actual font
glyphs so it can be rendered in a terminal. You'll need a font patched for the
Vim powerline to be able to use it. The default font used by Spacemacs Source
Code Pro
already contains the glyphs.
Separator scale
For spacemacs
, all-the-icons
and custom
themes you can specify the size of
the separator with the property :separator-scale
. It allows to avoid crappy
rendering of the separators like on the following screenshot.
Ugly separators
Example:
(setq dotspacemacs-mode-line-theme '(all-the-icons :separator-scale 1.5))
Note that this setting won't work correctly when the separator is utf-8
, if
you use this separator then it is recommended to set :separator-scale
to 1.0
.
Spacemacs mode-line theme
This theme is a heavily customized powerline using spaceline. It has the following capabilities among others:
- show the window number
- color code for current state
- show the number of search occurrences via anzu
- toggle flycheck info
- toggle battery info
- toggle minor mode lighters
Reminder of the color codes for the states:
Evil State | Color |
---|---|
Normal | Orange |
Insert | Green |
Visual | Grey |
Emacs | Blue |
Motion | Purple |
Replace | Chocolate |
Lisp | Pink |
Iedit/Iedit-Insert | Red |
Some elements can be dynamically toggled:
Key binding | Description |
---|---|
SPC t m b |
toggle the battery status |
SPC t m c |
toggle the org task clock (available in org layer) |
SPC t m m |
toggle the minor mode lighters |
SPC t m M |
toggle the major mode |
SPC t m n |
toggle the cat! (if colors layer is declared in your dotfile) |
SPC t m p |
toggle the point character position |
SPC t m r |
toggle responsivness of the mode-line |
SPC t m s |
toggle system monitor (displayed in the minibuffer) |
SPC t m t |
toggle the time |
SPC t m T |
toggle the mode line itself |
SPC t m v |
toggle the version control info |
SPC t m V |
toggle the new version lighter |
Flycheck integration
When Flycheck minor mode is enabled, a new element appears showing the number of errors, warnings and info.
Flycheck integration in mode-line
Anzu integration
Anzu shows the number of occurrence when performing a search. Spacemacs
integrates the Anzu status nicely by displaying it temporarily when n
or N
are being pressed. See the 5/6
segment on the screenshot below.
Anzu integration in mode-line
Battery status integration
fancy-battery displays the percentage of total charge of the battery as well as the time remaining to charge or discharge completely the battery.
A color code is used for the battery status:
Battery State | Color |
---|---|
Charging | Green |
Discharging | Orange |
Critical | Red |
Note: These colors may vary depending on your theme.
All-the-Icons theme
If you want to use this theme you need to make sure to install the required fonts from the package repository, see all-the-icons fonts directory.
Custom spaceline theme
You can create your own Spaceline theme by setting the variable
dotspacemacs-mode-line-theme
to custom
and define a function called
spaceline-custom-theme
in your dotspacemacs/user-init
function of your
dotfile. This function must accept a variadic number of arguments which are
additional segments added by Spacemacs (like a segment to notify about available
updates etc…).
Example:
(defun spaceline-custom-theme (&rest additional-segments)
"My custom spaceline theme."
(spaceline-compile
`(major-mode (minor-modes :when active) buffer-id)
`((line-column :separator " | " :priority 3)
,@additional-segments))
(setq-default mode-line-format '("%e" (:eval (spaceline-ml-main)))))
Restart Emacs and enjoy your very own mode-line!
Minor Modes
Spacemacs uses diminish mode to reduce the size of minor mode indicators:
The minor mode area can be toggled on and off with SPC t m m
Unicode symbols are displayed by default. Setting the variable
dotspacemacs-mode-line-unicode-symbols
to nil
in your ~/.spacemacs
will
display ASCII characters instead (may be useful in terminal if you cannot set an
appropriate font).
The letters displayed in the mode-line correspond to the key bindings used to toggle them.
Some toggle have two flavors: local and global. The global version of the toggle
can be reached using the control
key.
Additionally all globally available toggles have a circled unicode symbols like
ⓟ
. Toggles specific to a major mode under the SPC m T
prefix have plain
squared symbols like 🅿
.

Frame
Title
Default frame title displays name of current process and hostname of system. You
can include more information (like name of current file, name of current project
etc) by setting dotspacemacs-frame-title-format
variable.
Following format short codes are available:
Code | Description |
---|---|
%a |
the abbreviated-file-name , or buffer-name |
%t |
projectile-project-name |
%I |
invocation-name |
%S |
system-name |
%U |

%s |
process status |
%p |
percent of buffer above top of window, or Top, Bot or All |
%P |
percent of buffer above bottom of window, perhaps plus Top, or Bottom or All |
%m |
mode name |
%n |
Narrow if appropriate |
%z |
mnemonics of buffer, terminal, and keyboard coding systems |
%Z |
like %z, but including the end-of-line format" |
Iconified (tabified) title
If you are using tiling window manager with tab support you may want to display
different title for inactive tabs with dotspacemacs-icon-title-format
variable. Short codes are same as for frame title.
If this variable is set to nil
(default) its value will be same as
dotspacemacs-frame-title-format
.
Transparency
The Frame transparency can be toggled with: SPC T T
This also opens the Frame Transparency Transient State.
In the transient state:
Key binding | Description |
---|---|
+ , = , k |
increase transparency |
- , _ , j |
decrease transparency |
T |
toggle transparency on and off |
q |
quit transient state |
Layouts and workspaces
Layouts are window configurations with buffer isolation. Each layout can define several workspaces (think of them as sub-layouts), sharing the same list of buffers as their parent layout.
Layouts
A layout is a window configuration associated with a list of buffers. The list of buffers can be an arbitrarily chosen set of buffers. Spacemacs provides some facilities to create meaningful sets of buffers, for instance the buffers related to a projectile project.
The name of the current layout appears in the mode-line at the far left (first element of the mode-line).
To create a new layout, type a layout number that does not exist yet.
For instance if you have two layouts currently then type SPC l 3
to create a
third layout.
The default layout
The default
layout (the layout created at the startup of Emacs) is not
displayed in the mode-line but it is possible to display it by setting the
variable dotspacemacs-display-default-layout
to t
.
Its name is "default" by default but it can be changed by setting the variable
dotspacemacs-default-layout-name
.
The default
layout is special because it has a global scope which means that
all the opened buffers belong to it. So using only the default
layout feels
like not using layouts at all.
Project layouts
A project layout is bound to a projectile project. To create a project layout
use SPC p l
.
The name of the layout is the name of the project root directory.
Custom Layouts
Custom layouts can be defined using the macro spacemacs|define-custom-layout
,
they are accessible via SPC l o
.
By convention the name of a custom layout should start with @
.
Example of custom layout definition for ERC
buffers:
(spacemacs|define-custom-layout "@ERC"
:binding "E"
:body
(progn
;; hook to add all ERC buffers to the layout
(defun spacemacs-layouts/add-erc-buffer-to-persp ()
(persp-add-buffer (current-buffer)
(persp-get-by-name
erc-spacemacs-layout-name)))
(add-hook 'erc-mode-hook #'spacemacs-layouts/add-erc-buffer-to-persp)
;; Start ERC
(call-interactively 'erc)))
Then use SPC l o E
to start ERC inside its own layout. Any new ERC buffer
will be part of the custom layout.
Some custom layouts that ship with Spacemacs:
Name | Key binding | Description |
---|---|---|
@Spacemacs | e |
Custom perspective containing all buffers of ~/.emacs.d |
@Mu4e | m |
Custom perspective containing all mu4e buffers (needs the mu4e layer enabled) |
@ERC | E |
Custom perspective containing all ERC buffers (needs the erc layer enabled) |
@RCIRC | i |
Custom perspective containing all RCIRC buffers (needs the rcirc layer enabled) |
@Slack | s |
Custom perspective containing all Slack buffers (needs the slack layer enabled) |
@Org | o |
Custom perspective containing all the org-agenda buffers |
Save/Load layouts into a file
With SPC l s
and SPC l L
you can save and load layouts to/from a file.
Note: By default, Spacemacs will automatically save the layouts under the name
persp-auto-save
.
Setting the variable dotspacemacs-auto-resume-layouts
to t
will
automatically resume the last saved layouts.
Layout key bindings
The key bindings are registered in a transient state. The docstring of the
transient state displays the existing layouts and the currently active
layout has square brackets. Pressing a layout number will activate it (or
create a new one) and exit the transient state. It is possible to just preview a
layout with Ctrl-<number>
. Pressing TAB
will activate the previously

Behavior of SPC TAB with layouts
By default SPC TAB
which switches to last opened buffer is restricted to the
current layout. If there is only one opened buffer for a given layout then
SPC TAB
won't do anything and the following message is displayed in the
minibuffer:
Last buffer not found.
To allow SPC TAB
to switch to the last opened buffer from another layout set
this variable spacemacs-layouts-restrict-spc-tab
to nil
. For instance in
your used layer list with layer variables:
(spacemacs-layouts :variables spacemacs-layouts-restrict-spc-tab t)
Restrict a given function to the current layout
You can make any function "layout aware" by adding it to the list
spacemacs-layouts-restricted-functions
. It is not possible to change this
variable when Emacs is running. You have to define it using layer variables.
If you change this variable then Emacs must be restarted for the change to
take effect.
Default value for this variable is:
'(spacemacs/window-split-double-columns spacemacs/window-split-triple-columns spacemacs/window-split-grid)
If you want to add the function my-func
to this list you need to redefine
the complete list using layer variables:
(spacemacs-layouts :variables spacemacs-layouts-restricted-functions '(spacemacs/window-split-double-columns spacemacs/window-split-triple-columns spacemacs/window-split-grid my-func))
Workspaces
Workspaces are sub-layouts, they allow to define multiple layouts into a given layout, those layouts share the same buffers as the parent layout.
The currently active workspace number is displayed before the window number, for instance "➊|➍" or "1|4" means the fourth window of the first workspace.
Any new layout comes with a default workspace which is the workspace 1.
Switching to a workspace that does not exist in the current layout will create a
new one. For instance at startup you can press SPC l w 2
to create the
workspace 2 in the default
layout.
When created a workspace is anonymous, you can give them a name with
SPC l w R
.
Workspace key bindings
The key bindings are registered in a transient state. The docstring of the
transient state displays the existing workspaces and the currently active
workspace has square brackets. Pressing a workspace number will activate it (or
create a new one) and exit the transient state. It is possible to just preview a
workspace with Ctrl-<number>
. Pressing TAB
will activate the previously
selected workspace.

Commands
Vim key bindings
Spacemacs is based on the Vim
modal user interface to navigate and edit text.
If you are not familiar with the Vim
way of editing text, then you can try the
evil-tutor lessons by pressing SPC h T v
at any time.
Escaping
Spacemacs uses evil-escape to
easily switch between insert state
and normal state
by quickly pressing the
fd
keys.
The choice of fd
was made to be able to use the same sequence to escape from
"everything" in Emacs:
- escape from all stock evil states to normal state
- escape from evil-lisp-state to normal state
- escape from evil-iedit-state to normal state
- abort evil ex command
- quit minibuffer
- abort isearch
- quit magit buffers
- quit help buffers
- quit apropos buffers
- quit ert buffers
- quit undo-tree buffer
- quit paradox
- quit gist-list menu
- quit helm-ag-edit
- hide neotree buffer
If you find yourself in a buffer where the Spacemacs (SPC
) or Vim keybindings
don't work you can use this to get back to normal state
(for example in SPC
SPC customize
press fd
to make SPC b b
work again).
This sequence can be customized in your ~/.spacemacs
.
Example to set it to jj
:
(defun dotspacemacs/user-config ()
(setq-default evil-escape-key-sequence "jj"))
Note: Although jj
or jk
are popular choices of vim users, these key
sequences are not optimal for Spacemacs. Indeed it is very easy in visual
state
to press quickly jj
and inadvertently escape to normal state
.
Executing Vim and Emacs ex/M-x commands
Command | Key binding |
---|---|
Vim (ex-command) | : |
Emacs (M-x) | SPC SPC |
The emacs command key SPC
(executed after the leader key) can be changed
with the variable dotspacemacs-emacs-command-key
of your ~/.spacemacs
.
Leader key
On top of Vim
modes (modes are called states in Spacemacs) there is a
special key called the leader key which once pressed gives a whole new keyboard
layer. The leader key is by default SPC
(space). It is possible to change this
key with the variable dotspacemacs-leader-key
.
Major Mode leader key
Key bindings specific to the current major mode
start with SPC m
. For
convenience a shortcut key called the major mode leader key is set by default on
,
which saves one precious keystroke.
It is possible to change the major mode leader key by defining the variable
dotspacemacs-major-mode-leader-key
in your ~/.spacemacs
. For example to
setup the key on tabulation:
(setq-default dotspacemacs-major-mode-leader-key "<tab>")
Additional text objects
Additional text objects are defined in Spacemacs:
Object | Description |
---|---|
a |
an argument |
g |
the entire buffer |
l |
a line |
$ |
text between $ |
* |
text between * |
8 |
text between /* and */ |
% |
text between % |
\vert |
text between \vert |
Reserved prefix command for user
SPC o
and SPC m o
are reserved for the user. Setting key bindings behind
these is guaranteed to never conflict with Spacemacs default key bindings.
Example: Put (spacemacs/set-leader-keys "oc" 'org-capture)
inside
dotspacemacs/user-config
in your ~/.spacemacs
file, to be able to use
SPC o c
to run org mode capture.
Completion
Spacemacs is powered by one of two incremental completion and selection
narrowing frameworks: Helm (default) or Ivy. To use Ivy, add the ivy
layer to
your list of enabled layers. If the ivy
layer is not enabled, Helm will be
enabled automatically. (Please note that, as Helm is the more mature of the two,
some functions may be unavailable if you choose Ivy.)
These completion systems are the central control towers of Spacemacs, they are used to manage buffers, projects, search results, configuration layers, toggles and more…
Mastering your choice of completion system will make you a Spacemacs power user.
For more information go to the layers documentation for Helm and Ivy.
Note: To open the Spacemacs documentation for Helm of Ivy in Emacs, open the
spacemacs-help
menu with SPC h SPC
and type helm
or ivy
then return
.
Discovering
Key bindings
Which-key
A help buffer is displayed each time the SPC
key is pressed in normal mode.
It lists the available key bindings and their associated commands.
By default the which-key buffer will be displayed quickly after the key has been
pressed. You can change the delay by setting the variable
dotspacemacs-which-key-delay
to your liking (the value is in seconds).
Describe key bindings
It is possible to search for specific key bindings by pressing SPC ?
.
To narrow the list to some key bindings, use the leader key to type a pattern like
this regular expression: SPC\ b
which would list all buffer
related
bindings.
Getting help

---|---|
SPC h I |
Open Spacemacs GitHub issue page with pre-filled information |
SPC u SPC h I |
Open Spacemacs GitHub issue page with pre-filled information - include last pressed keys |
Note: To be able to report an issue you need to be logged into GitHub
Note: If these two bindings are used with the *Backtrace*
buffer open, the
backtrace is automatically included
Available layers
All layers can be easily discovered via spacemacs-help
accessible with
SPC h SPC
.
The following actions on the selected candidate are available:
- default: open the layer
README.org
- 2nd: open the layer
packages.el
Available packages in Spacemacs
spacemacs-help
also lists all the packages available in Spacemacs. The
entry format is (layer) packages
. If you type flycheck
you'll be able to see
all the layers where flycheck
is used.
The following actions are available on selected package:
- default: go the package init function
New packages from ELPA repositories
package-list-packages
is where you can browse for all available packages in the
different Elpa repositories. It is possible to upgrade packages from there but
it is not recommended, use the [Update Packages]
link on the Spacemacs startup
page instead.
Spacemacs uses Paradox instead of package-list-packages
to list available
ELPA packages. Paradox enhances the package list buffer with better feedbacks,
new filters and GitHub information like the number of stars. Optionally you can
also star packages directly in the buffer.
Important Note 1: Installing a new package from Paradox
won't make it
persistent. To install a package persistently you have to add it explicitly to a
configuration layer.
Important Note 2: Don't update your packages from Paradox
or
package-list-packages
because they don't support the rollback feature of
Spacemacs.

Smooth scrolling
smooth-scrolling prevent the point to jump when it reaches the top or bottom of the screen. It is enabled by default.
On Windows, you may want to disable it. To disable the smooth scrolling set the
dotspacemacs-smooth-scrolling
variable in your ~/.spacemacs
to nil
:
(setq-default dotspacemacs-smooth-scrolling nil)
You can also toggle smooth scrolling with SPC t v
.
Vim motions with avy
Spacemacs uses the evil
integration of avy which enables the
invocation of avy
during motions.
For instance, it is useful for deleting a set of visual lines from the current line.
Try the following sequence in a buffer containing some text: d SPC j l
, followed by
selecting an avy candidate.
Key binding | Description |

Unlike vim, emacs creates many buffers that most people do not need to see. Some
examples are the *Messages*
and *Compile-Log*
buffers. Spacemacs tries to
automatically ignore buffers that are not useful. However, you may want to
change the way Spacemacs marks buffers as useful. For instructions, see the
special buffer howto.

Auto-saving
Frequency of auto-saving
By default auto-saving of files is performed every 300 characters and
every 30 seconds of idle time which can be changed by setting to a
new value the variables auto-save-interval
and auto-save-timeout
respectively.
Location of auto-saved files
Auto-save of modified files can be performed in-place on the original file itself or in the cache directory (in this case the original file will remain unsaved). By default Spacemacs auto-save the file in the cache directory.
To modify the location set the variable dotspacemacs-auto-save-file-location
to original
or cache
.
Local files are auto-saved in a sub-directory called site
in the cache
directory whereas remote files (i.e. files edited over TRAMP) are auto-saved
in a sub-directory called dist
.
Disable auto-save
To disable auto-saving set the variable dotspacemacs-auto-save-file-location
to nil
.
You can toggle auto-save in a buffer by calling the command auto-save-mode
.
Searching
With an external tool
Spacemacs can be interfaced with different search utilities like:
The search commands in Spacemacs are organized under the SPC s
prefix with the
next key is the tool to use and the last key is the scope. For instance
SPC s a b
will search in all opened buffers using ag
.
If the last key (determining the scope) is uppercase then the current region or
symbol under point is used as default input for the search. For instance
SPC s a B
will search with symbol under point (if there is no active region).
If the tool key is omitted then a default tool will be automatically selected
for the search. This tool corresponds to the first tool found on the system of
the list dotspacemacs-search-tools
, the default order is rg
, ag
, pt
,
ack
then grep
. For instance SPC s b
will search in the opened buffers
using pt
if rg
and ag
have not been found on the system.
The tool keys are:
Tool | Key |
---|---|
ag | a |
grep | g |
ack | k |
rg | r |
pt | t |
The available scopes and corresponding keys are:
Scope | Key |
---|---|
opened buffers | b |
files in a given directory | f |
current project | p |
It is possible to search in the current file by double tapping the second key
of the sequence, for instance SPC s a a
will search in the current
file with ag
.
Notes:
rg
,ag
andpt
are optimized to be used in a source control repository but they can be used in an arbitrary directory as well.- It is also possible to search in several directories at once by marking them in the Helm buffer (not available in Ivy).
Beware if you use pt
, TCL parser tools also install a command line tool
called pt
.

Persistent highlighting
Spacemacs uses evil-search-highlight-persist
to keep the searched expression
highlighted until the next search. It is also possible to clear the highlighting
by pressing SPC s c
or executing the ex command :noh
.
Highlight current symbol
Spacemacs supports highlighting of the current symbol on demand (provided by auto-highlight-symbol mode) and adds a transient state to easily navigate and rename this symbol.
It is also possible to change the range of the navigation on the fly to:
- buffer
- function
- visible area
To initiate the highlighting of the current symbol under point press SPC s h
.
Navigation between the highlighted symbols can be done with the commands:
Key binding | Description |
---|---|
* |
initiate navigation transient state on current symbol and jump forwards |
# |
initiate navigation transient state on current symbol and jump backwards |
SPC s e |
edit all occurrences of the current symbol(/) |
SPC s h |
highlight the current symbol and all its occurrence within the current range |
SPC s H |
go to the last searched occurrence of the last highlighted symbol |
SPC t h a |
toggle automatic highlight of symbol under point after ahs-idle-interval seconds |
During the symbol highlight transient state, the following bindings are active:
Key binding | Description |
---|---|
e |
edit occurrences (*) |
n |
go to next occurrence |
N or p |
go to previous occurrence |
d |
go to next definition occurrence |
D |
go to previous definition occurrence |

change range (function , display area , whole buffer ) |
R |
go to home occurrence (reset position to starting occurrence) |
s |
search current buffer for symbol using ivy / helm |
b |
search all open buffers for symbol using ivy / helm |
f |
search files for symbol |
/ |
search current project for symbol |
z |

(*) using iedit or the default implementation of auto-highlight-symbol
The minibuffer displays the following information during the transient state:
Buffer [6/11]*
Where M [x/y]*
indicates:
-
M
: the current search scope, which is one of the following:Buffer
: whole buffer rangeDisplay
: current display rangeFunction
: current function range (dependent on the programming language major mode)
x
: the index of the current highlighted occurrencey
: the total number of occurrences*
: appears if there is at least one occurrence which is not currently visible.
Visual Star
With evil-visualstar you can search for the next occurrence of the current selection.
It is pretty useful combined with the expand-region bindings.
Note: If the current state is not the visual state
then pressing *
uses
auto-highlight-symbol and its transient state.
Listing symbols by semantic
To list all the symbols of a buffer press SPC s j
Editing
Paste text
Paste transient state
The paste transient state can be enabled by setting the variable
dotspacemacs-enable-paste-transient-state
to t
. By default it is disabled.
When the transient state is enabled, after you paste something, pressing C-j
or C-k
will replace the pasted text with the previous or next yanked (copied)
text on the kill ring.
For example if you copy foo
and bar
then press p
the text bar
will
be pasted, pressing C-j
will replace bar
with foo
.
Key binding | Description |
---|---|
p or P |
paste the text before or after point and initiate the paste transient state |
C-j |
in transient state: replace paste text with the previously copied one |
C-k |

Auto-indent pasted text
By default any pasted text will be auto-indented. To paste text un-indented use the universal argument.
It is possible to disable the auto-indentation for specific major-modes by
adding a major-mode to the variable spacemacs-indent-sensitive-modes
in your
dotspacemacs/user-config
function.

In iedit-insert state
Key binding | Description |
---|---|
ESC |
go back to iedit state |
C-g |
go back to normal state |
Examples
- manual selection of several words then replace:
v w w SPC s e S "toto" ESC ESC
- append text to a word on two lines:
v i w SPC s e J i "toto" ESC ESC
- substitute symbol with expand-region:
SPC v v e S "toto" ESC ESC
- replace symbol with yanked (copied) text with expand region:
SPC v e p ESC ESC
Replacing text in several files
If you have rg
, ag
, pt
or ack
installed, replacing an occurrence of text
in several files can be performed via helm-ag.
Say you want to replace all foo
occurrences by bar
in your current
project:
- initiate a search with
SPC /
- enter in edit mode with
C-c C-e
- go to the occurrence and enter in
iedit state
withSPC s e
- edit the occurrences then leave the
iedit state
- press
C-c C-c
Note: In Spacemacs, helm-ag
despite its name works with rg
, pt
and ack
as well (but not with grep
).
Renaming files in a directory
It is possible to batch rename files in a directory using wdired
from an
helm
session:
- browse for a directory using
SPC f f
- enter
wdired
withC-c C-e
- edit the file names and use
C-c C-c
to confirm the changes - use
C-c C-k
to abort any changes

Regular expressions
Spacemacs uses the packages pcre2el to manipulate regular expressions. It is
useful when working with Emacs Lisp
buffers since it allows to easily converts
PCRE
(Perl Compatible RegExp) to Emacs RegExp or rx
. It can also be used to
"explain" a PCRE RegExp around point in rx
form.
The key bindings start with SPC x r
and have the following mnemonic structure:
SPC x r <source> <target>
convert from source to targetSPC x r
do what I mean

Deleting files
Deletion is configured to send deleted files to system trash.
On macOS the trash
program is required. It can be installed with homebrew with
the following command:
$ brew install trash
To disable the trash you can set the variable delete-by-moving-to-trash
to
nil
in your ~/.spacemacs
.
Editing Lisp code
Editing of lisp code is provided by evil-lisp-state.
Commands will set the current state to lisp state
where different commands
combo can be repeated without pressing on SPC k
.
When in lisp state
the color of the mode-line changes to pink.
Examples:
- to slurp three times while in normal state:
SPC k 3 s
- to wrap a symbol in parentheses then slurp two times:
SPC k w 2 s
Note: The lisp state
commands are available in any modes! Try it out.

Keyboard macros
Keyboard macros are a powerful feature of Emacs. A keyboard macro is a record of keystrokes that can be replayed at any time.
Important note: When creating a macro, do not use the evil-escape
key
sequence (by default press fd
quickly), instead press the ESC
key
explicitly. Currently evil-escape
does not support being replayed in macros.
Vim keyboard macros
Spacemacs supports the VIM interface for creating macros in normal state using
q
to start a macro and @
to play a macro.
To record a keyboard macro:
- Press
q
(there's no visual indicator, but it's waiting for a letter key to be pressed). - Press a letter key to start recording to that letter register. (the minibuffer shows: Defining kbd macro…)
- Perform the actions that will be recorded.
- Press
q
to stop recording the macro. (the minibuffer shows: Keyboard macro defined).
To execute a recorded macro: (A macro can be played back multiple times, by typing a number before starting the macro)
- Press
@
(the minibuffer shows:@-
, and it waits for a letter register key to be pressed). - Press a letter key for a register where a previous macro has been recorded.
- The macro can be repeated by pressing the repeat last editing command key:
.
(period).
Emacs keyboard macros
The Emacs way to define macros is available behind the prefix: SPC K
To start recording a keyboard macro:
- Press
SPC K k
(uppercase then lowercase) to start recording a macro. - Perform the actions that should be recorded.
- Press
SPC K K
(uppercase twice) to stop recording the macro.
To execute the last recorded macro press: SPC K K
The macro can be executed again by pressing K
one or more times.
The single character replay works until another key than K
is pressed.
Macro counter
Emacs has an interesting concept: The macro counter.
When starting to record a macro, the counter starts at 0 (you can also set it to a specific value), then each time the counter is inserted, it is incremented by 1 afterwards.
When recording a macro it's possible to insert the current value by pressing:
SPC K k
Key bindings

Mouse usage
There are some added mouse features set for the line number margin (if shown):
- single click in line number margin visually selects the entire line
- drag across line number margin visually selects the region
- double click in line number margin visually select the current code block
Comparing (diff)
To compare buffers, files, directories or even windows use the prefix SPC D
.

to do comparisons, help for ediff
can be opened using SPC D h
.

---|---|
SPC r e |
show evil yank and named registers |
SPC r m |
show marks register |
SPC r r |

Errors management commands (start with e
):
Key binding | Description |
---|---|
SPC t s |
toggle flycheck |
SPC e c |

SPC e . |
error transient state |
The next/previous error bindings and the error transient state can be used to
browse errors from flycheck as well as errors from compilation buffers, and
indeed anything that supports Emacs' next-error
API. This includes for example
search results that have been saved to a separate buffer.
Error transient state
The following key bindings are active in the error transient state:
Key binding | Description |
---|---|
n |
jump to next error |
N or p |

EditorConfig
Spacemacs has support for EditorConfig, a configuration file to "define and maintain consistent coding styles between different editors and IDEs."
To enable this feature, install the editorconfig command.
To customize your editorconfig experience, read the editorconfig-emacs package's documentation.
Emacs Server
Spacemacs starts a server at launch. This server is killed whenever you close your Emacs windows.
Connecting to the Emacs server
You can open a file in Emacs from the terminal using emacsclient
. Use
emacsclient -c
to open the file in Emacs GUI. Use emacsclient -t
to open the
file in Emacs within the terminal. If you set Emacs server socket by setting dotspacemacs-server-socket-dir
,
then pass its location as -s ~/.emacs.d/server/server
additionally.
If you want your Linux or macOS system to use Emacs by default for any prompt,
you need to set it in your shell configuration, e.g. ~/.bashrc
or ~/.zshrc
:
export EDITOR="emacsclient -c"
Note that if you're using macOS, you may have to refer to the emacsclient that comes with your GUI Emacs, e.g.:
export EDITOR="/Applications/Emacs.app/Contents/MacOS/bin/emacsclient -c"
Tip: Remember to use :wq
or C-x #
after you are done editing the file in
Emacs.
You can set the location of the Emacs server socket by setting dotspacemacs-server-socket-dir
in your ~./spacemacs
:
(setq-default dotspacemacs-server-socket-dir "~/.emacs/server")
See Emacs as a Server in the official Emacs manual for more details.
Keeping the server alive
It is possible to keep the server alive when you close Emacs by setting the
variable dotspacemacs-persistent-server
to t
in your ~/.spacemacs
.
(setq-default dotspacemacs-persistent-server t)
When this variable is set to t
, the only way to quit Emacs and kill the
server is to use the following bindings:
Key binding | Description |
---|---|
SPC q q |
Quit Emacs and kill the server, prompt for changed buffers to save |
SPC q Q |
Quit Emacs and kill the server, lose all unsaved changes. |
SPC q r |
Restart both Emacs and the server, prompting to save any changed buffers |
SPC q s |
Save the buffers, quit Emacs and kill the server |
SPC q f |
Kill the current frame |
SPC q t |
Restart Emacs and debug with –with-timed-requires |
SPC q T |
Restart Emacs and debug with –adv-timers |
Disabling the Emacs server
You can disable the built-in server by setting the variable
dotspacemacs-enable-server
to nil
in your ~/.spacemacs
.
(setq-default dotspacemacs-enable-server nil)
Troubleshoot
Loading fails
If any errors happen during the loading the mode-line will turn red and the
errors should appear inline in the startup buffer. Spacemacs should still be
usable; if it is not then restart Emacs with emacs --debug-init
and open a
GitHub issue with the backtrace.
Upgrading/Downgrading Emacs version
To ensure that packages are correctly compiled for the new Emacs version you
installed, be sure to run the interactive command spacemacs/recompile-elpa
with SPC u SPC SPC spacemacs/recompile-elpa
.
General layer errors
It happens from time to time that some of the layers go stale and stop working properly for some commands. If this happens stay calm and try to produce a minimal bug report on the GitHub issue page.
Step by step instructions for minimal layer bug reports
- Load the standard dotfile. You can get it with
SPC f e D
. - Add the malfunctioning layer.
- Use
SPC t D
to enable debug on error, this will produce a backtrace when encountering a lisp error. - Reproduce the error. Note down the steps and backtrace.
- Press
SPC h I
and fill in the place holders enclosed in<<
and>>
signs. Don't forget the reproduction guide and backtrace. - Press
C-c C-c
or, ,
to transfer your buffers content to the github issue creation page. - Enter a meaningfull title for your issue, stating in short words what the issue is.
- When everything has been filled in submit the bug report.
- When someone answers to your issue or ask questions it goes without saying that you should answer him politely and assist in testing a possible fix.
General emacs package errors
It can also happen that your issue is not related to any layer but rather to a specific package in the emacs universe. In this case you should provide a minimalistic emacs only reproduction guide for the respective package and open an issue upstream. If there is already a spacemacs issue for your problem your upstream bug report should mention its ticket number so it is clear when this issue can be retested.
Step by step instructions for minimal emacs package bug reports
- Start emacs with
emacs -q
, this will load a vanilla emacs without any non-system packages loaded. - There open a scratch buffer with
C-x b *scratch* RET
-
Add initialization code for your package there
;; Load the package (require 'package) ;; Mention all packages you wish to have loaded (setq package-load-list '((package1 t) (package2 t) (package3 t))) ;; Do package specific configuration if required ;; (package-local-init) ;; Intialize your package list (package-initialize)
- Now press
M-x eval-buffer
to evaluate the code. - Reproduce your issue. Note down step by step instructions.
- With this information open an upstream issue following their issue templates. If they have non its a good idea to start with the infos required in the spacemacs issue template and add missing information when required from the package maintainers.
