## Goals
- The main goal of `Spacemacs` is to **bring the power of Vim modal editing
to the powerful Emacs editing platform**.
- Slick integration with Evil states/Vi modes, tries as much as possible to
**keep your fingers on the home row**, no matter the mode you are in.
- **Lower the risk of RSI**, your hands will thank `Spacemacs`.
- **Community driven configuration** based on a configuration layer system
*(work in progress)*. Contribute your own personal layer upstream and
everybody can use it.
- **Minimalistic and nice custom UI**, keep your available screen space for
what matters: your text files.
- Hopefully, if it's not already the case: make you love modal editing :-)
## Screenshots

![scr_python](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/doc/spacemacs.png)
*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` is first intended to be used by **Vim users** who want to go to the
next level by using Emacs.
It is also a good fit for people wanting to **lower the [risk of RSI][RSI]**
induced by the default Emacs key bindings.
People wanting to learn **a different way to edit files** or wanting to learn
Vim key bindings.
As a note side, if you are a programmer and you don't know Vim key bindings
yet, I deeply recommend you to learn the basics as recommended in
[Sacha Chua's one-page guide][sacha_guide] about how to learn Emacs.
## Install
`Spacemacs` is tested with `Emacs 24.3.1` on `Ubuntu 14.04`, `Mac OS X 10.10`,
`Windows 7`.
Backup your current `.emacs.d`, clone the repo. _with the submodules_ and
you are good to go:
cd ~
mv .emacs.d .emacs.bak
git clone --recursive http://github.com/syl20bnr/spacemacs .emacs.d
## Configuration layers
**work in progress**
## Contributions
`Spacemacs` leverages the configuration layers in order to make it possible for
you to share your own layer with other `Spacemacs` users.
**The contribution system is a work in progress**
Anyway, pull requests are welcome for all parts of `Spacemacs`.
## Main principles
`Spacemacs` uses the [evil][evil] mode to emulate Vim key bindings. It is a
very complete emulation (the most complete I've seen yet).
`Spacemacs` heavily uses the [evil-leader][evil-leader] mode which brings the
Vim leader key to the Emacs world.
This leader key is commonly set to `,` by Vim users, in `Spacemacs` the leader
key is set on `SPC` (space bar, this is why 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][RSI].
So 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 with `helm`: `<SPC> b s`
## UI and syntax highlighting
`Spacemacs` has a minimalistic and distraction free UI with a lot of subtle
customizations which make it unique compared to other Emacs kits:
- custom [powerline][powerline] mode-line [with color feedback](#mode-line)
according to current [Flycheck][flycheck] status
- unicode symbols for minor mode lighters which appear in the mode-line
- [custom fringe bitmaps](#errors-handling) and error feedbacks for
[Flycheck][flycheck]
- custom fringe bitmaps for [git gutter][git-gutter].
- dedicated startup page with a mode aimed at easily managing `Spacemacs`
`Spacemacs` syntax highlighting is also different from the majority of other
Emacs configurations: instead of colorized keywords, `Spacemacs` has *colorized
variables and functions* using the [rainbow identifiers][rainbow-identifiers]
mode. Each variable and function has a unique color associated to it.
## Commands
Every sequences must be performed in `normal` mode.
### Return to normal mode
`ESC` is the default key to return to normal mode. This is one of the main
design flaw in Vim key bindings because the `ESC` key is very far from the
home row.
The popular way to avoid this is to replace `ESC` by `jj` pressed rapidly.
`Spacemacs` proposes to press `fd` instead and reserves the zone around `j`
for text reformatting.
`fd` also works to quit the minibuffer.
**Note:** For those who know about [keychords.el][keychords] mode. This mode is
not used to return to the normal mode, the reason for this is latency and the
fact that keychords wants you to press several keys at almost the same time
which is something very difficult to master correctly on a keyboard.
`Spacemacs` has a special function called `fd-trigger` to handle the `fd` key
sequence and fix the above keychords issues.
### Executing Vim and Emacs commands
Vim commands are executed as usual with the `:` key.
To execute an Emacs command press `<SPC>` (space) before:
<SPC> :
### Key bindings help
A list of all the key bindings can be accessed by pressing:
<SPC> ?
To narrow the list to `Spacemacs` specific key bindings set the pattern to `SPC`
### Included Evil plugins
`Spacemacs` ships with the following evil plugins:
Mode | Description
----------------------------------------|--------------------------------------
[evil-leader][evil-leader] | vim leader that bring a new layer of keys in normal mode
[evil-little-word][evil-plugin01] | port of [camelcasemotion.vim][vim-plugin01]
[evil-operator-comment][evil-plugin01] | comment/uncomment with `CC`
[evil-visualstar][evil-plugin03] | search for current selection with `*`
[evil-exchange][evil-plugin05] | port of [vim-exchange][vim-plugin04]
[surround][evil-plugin04] | port of [surround.vim][vim-plugin03]
### About helm
`Spacemacs` tries to use [helm][helm] as much as possible.
[helm][helm] is coupled to [popwin][popwin] so `helm` window always appears in
a new temporary windows at the bottom.
The following `helm` modes are installed with `Spacemacs`:
Key Binding | Mode | Description
------------|-----------------------------------------|------------------------
`<SPC> h s` | [helm-swoop][hswoop] | search for occurrences within a file and edit the result
`<SPC> h c` | [helm-css-scss][hcss] | for quick navigation in CSS
`<SPC> h y` | [helm-c-yasnippet][hyas] | select snippets
`<SPC> h t` | [helm-themes][hthemes] | select a theme
`<SPC> p f` | [helm-projectile][projectile] | select files within a projectile project
`<SPC> ?` | [helm-descbinds][hdescbinds] | show key bindings
`<SPC> s c` | [cofi/helm-flyspell-correct][hflyspell] | choose a corrected word
### Navigation
#### Point/Cursor
Navigation is performed using the Vi key bindings `hjkl`.
Key Binding | Description
------------|------------------------------------------------------------------
`h` | move cursor left
`j` | move cursor down
`k` | move cursor up
`l` | move cursor right
`H` | move quickly up (10 lines at a time)
`L` | move quickly down (10 lines at a time)
`<SPC> j h` | go to the beginning of line (and set a mark at the previous location in the line)
`<SPC> j l` | go to the end of line (and set a mark at the previous location in the line)
`<SPC> z z` | lock the cursor at the center of the screen
#### Vim motions with ace-jump mode
`Spacemacs` uses the `evil` integration of [ace-jump mode][ace-jump] which
enables the invocation of `ace-jump-mode` during motions.
It is useful for deleting visually a set of lines, try the following sequence
in a buffer containing some text:
d <SPC> l
Key Binding | Description
--------------|------------------------------------------------------------------
`<SPC> <SPC>` | initiate ace jump char mode
`<SPC> l` | initiate ace jump line mode
``<SPC> ``` | go back to the previous location (before the jump)
#### Buffers and Files
`Spacemacs` uses `ido` for opening files since `ido` way to navigate
the file system is better than `helm` in my opinion (especially because `ido` can
remember the last selected directories and buffers, maybe helm can do this ?).
`ido` is also used to kill buffers.
Buffer manipulation commands (start with `b`):
Key Binding | Description
--------------|----------------------------------------------------------------
`<SPC> b d` | delete the current buffer (beware the associated file is also deleted)
`<SPC> b k` | kill the current buffer
`<SPC> b K` | kill all buffers except the current one
`<SPC> b m h` | move a buffer to the left
`<SPC> b m j` | move a buffer to the bottom
`<SPC> b m k` | move a buffer to the top
`<SPC> b m l` | move a buffer to the right
`<SPC> b n` | switch to next buffer
`<SPC> b p` | switch to previous buffer
`<SPC> b r` | rename the current buffer
`<SPC> b s` | switch to a buffer using `helm`
`<SPC> b w` | toggle read-only
Files manipulation commands (start with `f`):
Key Binding | Description
--------------|----------------------------------------------------------------
`<SPC> f f` | open a file using `ido`
`<SPC> f i` | open your `init.el` file
`<SPC> f s` | save a file
`<SPC> f S` | save all files
`<SPC> f y` | show current file absolute path in the mini buffer
#### Bookmarks
Bookmarks can be set anywhere in a file. Bookmarks are persistent. They are very
useful to jump to/open a known project. `Spacemacs` used `helm-bookmarks` to
manage them.
Open an `helm` window with the current bookmarks by pressing:
<SPC> h b
Then in the `helm-bookmarks` buffer:
Key Binding | Description
--------------|----------------------------------------------------------------
`CTRL+d` | delete the selected bookmark
`CTRL+e` | edit the selected bookmark
`CTRL+f` | toggle filename location
`CTRL+o` | open the selected bookmark in another window
To save a new bookmark, just type the name of the bookmark and press `RET`.
### Window manipulation
Split windows are dynamically resized depending on whether they are selected or
not. Resizing is performed by the [golden-ratio][golden-ratio] mode.
Every window has a number displayed at the start of the mode-line and can
be quickly accessed using `<SPC> number`.
Key Binding | Description

`<SPC> w L` | move window to the right
`<SPC> w m` | maximize/minimize a window
`<SPC> w M` | maximize/minimize a window, when maximized the buffer is centered
`<SPC> w p` | close the current sticky popup window
`<SPC> w r` | rotate windows clockwise
`<SPC> w R` | rotate windows counter-clockwise
`<SPC> w u` | undo window layout (used to effectively undo a close window)

`<SPC> s c` | list of corrections in a `helm` buffer
`<SPC> s d` | change dictionary language
`<SPC> s n` | go to the next spell check error
### Region selection
Vi `Visual` modes are all supported by `evil`, `Spacemacs` adds another
`Visual` mode via the [expand-region][expand-region] mode.
Key Binding | Description
--------------|----------------------------------------------------------------
`<SPC> v` | initiate expand-region mode then...
`v` | expand the region by one semantic unit
`V` | contract the region by one semantic unit
`r` | reset the region to initial selection
`ESC` | leave expand-region mode
### Region narrowing
The displayed text of a buffer can be narrowed with the commands
(start with `n`):
Key Binding | Description
--------------|----------------------------------------------------------------
`<SPC> n f` | narrow the buffer to the current function
`<SPC> n p` | narrow the buffer to the visible page
`<SPC> n r` | narrow the buffer to the selected text
`<SPC> n w` | widen, i.e show the whole buffer again
### Auto highlight
`Spacemacs` supports auto highlighting of the current word (provided by the
[auto-highlight-symbol][auto-highlight] mode).
Key Binding | Description
--------------|----------------------------------------------------------------
`<SPC> h e` | edit all occurrences of the current word
`<SPC> h n` | go to next occurrence
`<SPC> h p` | go to previous occurrence
`<SPC> t h` | toggle the auto highlighting
### Color theme
By default, `Spacemacs` uses the theme [Solarized][solarized-theme].
Key Binding | Description
------------------|------------------------------------------------------------
`<SPC> c t` | cycle between `Spacemacs` themes
`<SPC> h t` | select a theme using a `helm` buffer
`Spacemacs` available themes:
- [Solarized][solarized-theme]
- [Monokai][monokai-theme]
- [Zenburn][zenburn-theme]
### UI elements
#### Mode-line
The mode line is a [powerline][powerline] customized to show the window
number and the colorized Evil current state.
The color codes for modes are:
Evil State | Color
------------------|------------------
Normal | Orange
Insert | Green
Visual | Grey
Emacs | Red
Motion | Purple
When [Flycheck][flycheck] minor mode is enabled, the mode line color changes
according to the current flycheck state:
![flycheck-error](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/doc/flycheck-error.png)
![flycheck-warning](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/doc/flycheck-warning.png)
![flycheck-info](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/doc/flycheck-info.png)
#### Toggles
Some UI indicators can be toggled on and off (toggles start with `t`):
Key Binding | Description
------------------|------------------------------------------------------------
`<SPC> t 8` | display a mark on the 80th column
`<SPC> t f` | toggle display of the fringe
`<SPC> t n` | show the absolute line numbers
### Minor Modes
`Spacemacs` uses [diminish][diminish] mode to reduce the size of minor mode
indicators:
The minor mode area can be toggled on and off with:
<SPC> t m
Lighter | Mode
-------------|-----------------------------------------------------------------
Ⓐ | [auto-complete][auto-complete] mode
Ⓗ | [auto-highlight-symbol][auto-highlight] mode
Ⓒ | [centered-cursor][centered-cursor] mode
eⓅ | [e-project][e-project] mode
Ⓟ | [projectile][projectile] mode
Ⓕ | flymake mode
Ⓢ | flyspell mode
(Ⓢ) | [smartparens][sp] mode
(Ⓟ) | paredit mode
Ⓨ | [yasnippet][yasnippet] mode
**Note:** in terminal the regular indicators are used instead of the utf-8
ones.
### Line formatting
`Spacemacs` replaces the default `J` Vi key binding (join current line with next
line) by a slightly more frequent action which is to `go to the line below point
and indent it`.
Join lines can still be performed with `<SPC> j k`
Line formatting commands start with `j`:
Key Binding | Description
------------------|------------------------------------------------------------
`J` | go to next line and indent it using auto-indent rules
`<SPC> j j` | same as `J` but will split the current line at point
`<SPC> J` | split a quoted string or s-expression in place
`<SPC> j J` | split a quoted string or s-expression and auto-indent
`<SPC> j k` | join the current line with the next line
Used together these key bindings are very powerful to quickly reformat the code.
### Errors handling
`Spacemacs` uses [Flycheck][flycheck] to gives error feedback on the fly.
The checks are only performed at save time by default.
Errors management commands (star with `f` for `flycheck`):
Key Binding | Description
------------------|------------------------------------------------------------
`<SPC> f c` | clear all errors
`<SPC> f l` | display the `flycheck` list of errors/warnings
`<SPC> f n` | go to the next `flycheck` error
`<SPC> f p` | go to the previous flycheck error
Custom fringe bitmaps:
Symbol | Description
:----------------------------------------------------------------------------------------------:|------------

![dot-info](https://raw.githubusercontent.com/syl20bnr/spacemacs/master/doc/dot-info.png) | Info
### Project management
Projects in `Spacemacs` are managed with [projectile][projectile].
So projects are defined implicitly, for instance the root of a project
is found when a `.git` repository or `.projectile` file is encountered
in the file tree.

`<SPC> p b` | switch to a buffer of the project
`<SPC> p C` | invalidate the cache of `projectile`
`<SPC> p d` | open a `dired` buffer at the root of the project

## Troubleshoot
### Marmalade repository is down
Unfortunately for now there is little you can do in `Spacemacs` if `marmalade`
repository goes down and you need to install packages. Though there will be
solutions in a future release of the contribution system.
## TODO list
- Add support for [multiple-cursors][multiple-cursors] mode.
