# Introduction
Spacemacs is a new way to experience Emacs -- a sophisticated and
polished set-up focused on ergonomics, mnemonics and consistency.
Just clone it, launch it, then press the space bar to explore the
interactive list of carefully-chosen key bindings. You can also press
the home buffer's `[?]` button for some great first key bindings to
try.
Spacemacs can be used naturally by both Emacs and Vim users -- you can
even mix the two editing styles. Switching easily between input styles
makes Spacemacs a great tool for pair-programming.
Spacemacs is currently in beta, and contributions are very welcome.
# Features
- **Great documentation:** Access documentation in Emacs with
SPC f e h
- **Beautiful GUI:** you'll love the distraction free UI and its functional
mode-line.
- **Excellent ergonomics:** all the key bindings are accessible by pressing
the space bar or alt-m.
- **Mnemonic key bindings:** commands have mnemonic prefixes like
SPC b for all the buffer commands or SPC p for the
project commands.
- **Batteries included:** discover hundreds of ready-to-use packages nicely
organised in configuration layers following a set of
[conventions][CONVENTIONS.org].
# Documentation
A comprehensive documentation is available for each layer by pressing
SPC f e h.
To go to the general documentation [click here][DOCUMENTATION.org].
You can also check the [Quick Start guide][QUICK_START.org] and the
[FAQ][FAQ.org].
# Getting Help
If you need help, ask your question in the [Gitter Chat][] and a member of the
community will help you out.
If you prefer IRC, connect to the [Gitter Chat IRC server][] and join the
`#syl20bnr/spacemacs` channel.
# Prerequisites
## Emacs
Spacemacs is operational with Emacs 24.3 but Emacs 24.4 and above are
recommended to enjoy the full experience.
Some modes require third-party tools that you'll have to install via your
favorite package manager.
### Linux distros
Install Emacs from the package manager of your Linux distribution.
You should install the "emacs" package, not the "xemacs" package.
XEmacs is an old fork of Emacs. The X in its name is unrelated to X11.
Both Emacs and XEmacs have graphical support.
### OS X
We recommend the homebrew [emacs-mac-port][] formula:
```sh
$ brew tap railwaycat/homebrew-emacsmacport
$ brew install emacs-mac --with-spacemacs-icon # OR, brew cask install emacs-mac
```
It is also recommended to add the [osx layer][] to your [dotfile][]:
```elisp
(setq-default dotspacemacs-configuration-layers '(osx))
```
Note that the `emacs-mac-port` server behaves differently than the regular Emacs
server which in particular **DOES NOT** allow multi-tty if you start GUI i.e.
you can't connect to the Emacs GUI server with `emacsclient` but server-client
works if you start from terminal(TTY-only).
Details can be found on the emacs-mac-port [README][emacs-mac-port-server].
### Windows
Good quality builds can be found [on this page][emacs-for-windows]. It is
recommended to install the most stable build.
Be sure to declare a environment variable named `HOME` pointing to your user
directory `C:\Users\`. Then you can clone Spacemacs in this directory.
Sometimes you'll get the following error when you first start Emacs:
```
The directory ~/.emacs.d/server is unsafe
```
To fix it change the owner of the directory `~/.emacs.d/server`:
- from Properties select the Tab “Security”,
- select the button “Advanced”,
- select the Tab “Owner”
- change the owner to your account name
Source: [Stackoverflow][so-server-unsafe]
For efficient searches we recommend to install `pt` ([the platinum searcher][]).
`pt` version 1.7.7 or higher is required.
# Install
1. If you have an existing Emacs configuration, back it up first:
```sh
cd ~
mv .emacs.d .emacs.d.bak
mv .emacs .emacs.bak
```
2. Clone the repository:
```sh
git clone --recursive https://github.com/syl20bnr/spacemacs ~/.emacs.d
```
`master` is the stable branch and it is _immutable_, **DO NOT** make any
modification to it or you will break the update mechanism. If you want to
fork Spacemacs safely use the `develop` branch where you handle the update
manually.
3. Launch Emacs. Spacemacs will automatically install the packages it requires.
4. Restart Emacs to complete the installation.
If the mode-line turns red then be sure to visit the
[troubleshooting][troubleshoot] guide and consult the [FAQ][FAQ.org].
## Spacemacs logo
If you are using Ubuntu and Unity then you can add the Spacemacs logo by
following the instructions [here][cpaulik-unity-icon].
If you're on a mac follow [these instructions][icon-mac-instructions]. You can
find an .icns version of the logo by [Nasser Alshammari](http://www.nass3r.com)
in [his repository][icon-repository].
# Update
Spacemacs has a built-in notification of a new version when you are on the
`master` branch. If you are on the `develop` branch then you'll have to
update Spacemacs manually by updating your repository.
## Automatic update
When a new version is available a little arrow appears in the mode-line.
Its color depends on the number of versions available since your last update.
Green means that your current version is recent, orange and red that your
current version is older.
Click on the arrow to update Spacemacs to the last version.
## On develop branch
1. Update Emacs packages by clicking (press `RET`) on the `[Update]` link of
the starting page.
2. Close Emacs and update the git repository:
```sh
git pull --rebase
```
3. Restart Emacs to complete the upgrade.
## Revert to a specific version
To revert to a specific version you just have to checkout the corresponding
branch, for instance to revert to the last `0.103`:
```sh
git checkout origin/release-0.103
```
