# Introduction
|
|
Spacemacs is a new way of experiencing Emacs -- it's a sophisticated and
|
|
polished set-up, focused on ergonomics, mnemonics and consistency.
|
|
|
|
Just clone and 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. Being able to quickly switch between input styles, makes
|
|
Spacemacs a great tool for pair-programming.
|
|
|
|
Spacemacs is currently in beta, and any contributions are very welcome.
|
|
|
|
|
|
|
|
# Features
|
|
- **Great documentation:** access the Spacemacs documentation with
|
|
<kbd>SPC h SPC</kbd>.
|
|
- **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
|
|
<kbd>space bar</kbd> or <kbd>alt-m</kbd>.
|
|
- **Mnemonic key bindings:** commands have mnemonic prefixes like
|
|
<kbd>SPC b</kbd> for all the buffer commands or <kbd>SPC p</kbd> 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
|
|
Comprehensive documentation is available for each layer by pressing
|
|
<kbd>SPC h SPC</kbd>.
|
|
|
|
You can also check the [general documentation][DOCUMENTATION.org],
|
|
[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
|
|
Spacemacs is an extension of a popular text editor called Emacs. Thus you need
|
|
to first install base Emacs and then download the Spacemacs extension files with
|
|
Git.
|
|
|
|
## Emacs
|
|
Spacemacs requires Emacs 24.4 or above. The development version of Emacs is not
|
|
*officially* supported, but it should nevertheless be expected to work.
|
|
|
|
Some modes require third-party tools that you'll have to install via your
|
|
favorite package manager.
|
|
|
|
### Linux distros
|
|
Install the `emacs` package with your linux distributions package manager.
|
|
|
|
Do not install the `xemacs` package. It's not supported by Spacemacs. XEmacs is
|
|
an old fork of Emacs. The X in its name is unrelated to X11.
|
|
|
|
Emacs has graphical support.
|
|
|
|
**Note:** The Ubuntu LTS 12.04 and 14.04 repositories only have Emacs version
|
|
24.3 available. Version 24.4 or greater needs to be [built from source][build_source].
|
|
This might also be true for other linux distributions.
|
|
|
|
### macOS
|
|
The recommended way of installing Emacs on macOS is using [Homebrew][]. It's a
|
|
package manager for macOS. Once Homebrew is installed, run the following
|
|
commands in the terminal to install both Emacs and the default Source Code Pro
|
|
font:
|
|
|
|
```sh
|
|
brew tap d12frosted/emacs-plus
|
|
brew install emacs-plus
|
|
brew linkapps emacs-plus
|
|
brew tap caskroom/fonts
|
|
brew cask install font-source-code-pro
|
|
git clone https://github.com/syl20bnr/spacemacs ~/.emacs.d
|
|
```
|
|
|
|
**Notes:**
|
|
The proposed `emacs-plus` tap is identical to the `emacs` formulae, it just
|
|
builds GNU Emacs with support for several features by default, including the
|
|
Spacemacs icon. See [emacs-plus][] for more information.
|
|
|
|
After completing the Spacemacs [install process](#install), then it's also
|
|
recommended to add the [osx layer][] to your [dotfile][]. Installation
|
|
instructions are available in the documentation for the [osx layer][].
|
|
|
|
If the powerline separators on the spaceline have a different (less saturated)
|
|
color than the rest of the line, then you can add the following snippet to the
|
|
`dotspacemacs/user-config` section in your `~/.spacemacs` file:
|
|
|
|
```elisp
|
|
(setq ns-use-srgb-colorspace nil)
|
|
```
|
|
|
|
Keep in mind that this is not an ideal solution as it affects all colours in
|
|
Emacs. Another option is to change the powerline separators. For example to
|
|
`alternate` or `bar`, they diminish the color difference. Or change them to
|
|
`utf-8`, which makes them go away completely, without having to change colour
|
|
space. In order to change the powerline separators, put the following snippet in
|
|
the `dotspacemacs/user-config` section of your `~/.spacemacs` file:
|
|
|
|
```eslip
|
|
(setq powerline-default-separator 'utf-8)
|
|
```
|
|
|
|
For more information about powerline separators, please refer to the
|
|
[powerline documentation][]
|
|
|
|
### Windows
|
|
You can download good quality builds from the [emacs-w64 project][emacs-for-windows].
|
|
It is recommended to install the most recent [stable build][emacs-for-windows-stable].
|
|
|
|
Be sure to declare an environment variable named `HOME` that's pointing to your
|
|
user directory `C:\Users\<username>`. Then you can clone Spacemacs into that
|
|
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: [Stack Overflow][so-server-unsafe]
|
|
|
|
For efficient searches we recommend installing `pt` ([the platinum searcher][]).
|
|
`pt` version 1.7.7 or higher is required.
|
|
|
|
# Install
|
|
## Default installation
|
|
1. If you have an existing Emacs configuration, back it up first by running the
|
|
following code in your terminal:
|
|
|
|
```sh
|
|
cd ~
|
|
mv .emacs.d .emacs.d.bak
|
|
mv .emacs .emacs.bak
|
|
```
|
|
|
|
Don't forget to backup and *remove* the `~/.emacs` file. Otherwise Spacemacs
|
|
**WILL NOT** be able to load. Because that file prevents Emacs from loading
|
|
the proper initialization file.
|
|
|
|
2. Clone the repository with [Git][]:
|
|
|
|
```sh
|
|
git clone 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'll handle updates
|
|
manually.
|
|
|
|
**Note for Windows users**
|
|
If you use windows, then you'll have to modify the git command by inserting
|
|
the correct path to your `.emacs.d` folder. The dot before the folder means
|
|
that it's hidden. You'll have to search for hidden files to find the folder.
|
|
When you have found the folder, substitute the original path with the correct
|
|
one. The proper code would look something like this:
|
|
|
|
```sh
|
|
git clone https://github.com/syl20bnr/spacemacs /path/to/your/.emacs.d
|
|
```
|
|
|
|
3. Install the default fonts
|
|
|
|
It's recommended to install [Source Code Pro][] by Adobe, as the default
|
|
font. It ensures that, for example the symbols on the modeline (bottom bar)
|
|
looks correct. It's also recommended to use a "Fallback font". These
|
|
depend on the system:
|
|
|
|
- GNU/Linux: *NanumGothic* (package named *fonts-nanum* on Debian, for
|
|
example)
|
|
- macOS: *Arial Unicode MS*
|
|
- Windows: *MS Gothic* or *Lucida Sans Unicode*
|
|
|
|
If the modeline doesn't look similar to the
|
|
[picture at the top of this page](#introduction), then make sure you have the
|
|
correct fallback font installed.
|
|
|
|
If you're running in a terminal then you'll also need to change the terminals
|
|
font settings.
|
|
|
|
4. Launch Emacs, and answer the questions in the Dotfile wizard installer. If
|
|
you are new to Emacs and Spacemacs, then it's fine to just accept the default
|
|
choices. It's easy to try the other choices later, without having to
|
|
reinstall Spacemacs. They can be changed in the dotfile `~/.spacemacs`.
|
|
|
|
After answering the questions, then Spacemacs starts downloading and
|
|
installing the packages it requires. When the packages have been installed.
|
|
Restart Emacs to complete the installation.
|
|
|
|
**Notes:**
|
|
If you get an error regarding package downloads, then you can try to
|
|
disable the HTTPS protocol by starting Emacs with the `--insecure` argument:
|
|
|
|
```sh
|
|
emacs --insecure
|
|
```
|
|
|
|
Or you can set the `dotspacemacs-elpa-https` variable to `nil` in your
|
|
dotfile `~/.spacemacs`. That will remove the need to start Emacs with the
|
|
`--insecure` argument. You may also want to clear out your `.emacs.d/elpa`
|
|
directory before doing this, so that any corrupted packages you may have
|
|
downloaded will be re-installed.
|
|
|
|
`error: Package 'package-build-' is unavailable` may occur due to heavy network
|
|
taffic. You can fix it by setting the `dotspacemacs-elpa-timeout` variable to
|
|
`70` in your dotfile.
|
|
|
|
`Warning (bytecomp)` and other compilation warnings are perfectly normal. If
|
|
you're curious, you can find out why these occur [here][compilation-warnings].
|
|
|
|
If the mode-line turns red then be sure to consult the [FAQ][FAQ.org].
|
|
|
|
## Alternative installations
|
|
There are currently, two supported, alternative locations, for a Spacemacs
|
|
configuration.
|
|
|
|
### Modify HOME environment variable
|
|
This solution is ideal for quickly trying Spacemacs without compromising your
|
|
existing configuration. Clone Spacemacs outside the Emacs dotdirectory
|
|
`~/.emacs.d` and modify the HOME environment variable.
|
|
|
|
```sh
|
|
mkdir ~/spacemacs
|
|
git clone https://github.com/syl20bnr/spacemacs.git ~/spacemacs/.emacs.d
|
|
HOME=~/spacemacs emacs
|
|
```
|
|
|
|
Note: If you're using the Fish shell, then you'll need to modify the last
|
|
command to: `env HOME=$HOME/spacemacs emacs`
|
|
|
|
### Modify spacemacs-start-directory variable
|
|
This solution is better suited to "embed" Spacemacs into your own configuration.
|
|
If you've cloned Spacemacs into `~/.emacs.d/spacemacs/`, then drop the following
|
|
lines in the `~/.emacs.d/init.el` file:
|
|
|
|
```elisp
|
|
(setq spacemacs-start-directory "~/.emacs.d/spacemacs/")
|
|
(load-file (concat spacemacs-start-directory "init.el"))
|
|
```
|
|
|
|
## Spacemacs logo
|
|
For Ubuntu users, follow this guide to
|
|
[change the logo in Unity][cpaulik-unity-icon].
|
|
|
|
For Mac users, you need to [download the .icns version of the logo][icon-repository],
|
|
then [change the logo on the Dock][icon-mac-instructions].
|
|
|
|
# Update
|
|
Spacemacs shows a notification when a new version is available (only when you
|
|
are on the default `master` branch). If you are on the `develop` branch then
|
|
you'll have to update the Spacemacs repository manually.
|
|
|
|
## Automatic update (on master branch)
|
|
When a new version is available then a little arrow appears in the mode-line.
|
|
|
|
Its color depends on the number of versions that have been released since your
|
|
last update. Green means that you have a recent version, orange and red means
|
|
that you have an older version.
|
|
|
|
|
|
|
|
Click on the arrow to update Spacemacs to the latest version.
|
|
|
|
## Manual update (on master branch)
|
|
Remove the `<` and `>` angle brackets when you're typing the lines below into
|
|
your shell. And replace the text: "tag version which you are updating to" with a
|
|
tagged version. This page lists the [latest tags][]
|
|
|
|
```sh
|
|
git fetch
|
|
git reset --hard <tag version which you are updating to>
|
|
```
|
|
|
|
## On develop branch
|
|
1. Close Emacs and update the git repository:
|
|
|
|
```sh
|
|
git pull --rebase
|
|
```
|
|
|
|
2. Restart Emacs to complete the upgrade.
|
|
|
|
## Revert to a specific version
|
|
To revert to a specific version, just checkout the corresponding branch. For
|
|
instance to revert to version `0.200`, type the following command:
|
|
|
|
```sh
|
|
git checkout origin/release-0.200
|
|
```
|
|
|
|
**After updating Spacemacs (either manually or automatically), then you also
|
|
should check if any updates are available for your packages. On the Spacemacs
|
|
Home Buffer `SPC b h`, click (press `RET`) on the `[Update Packages]` button.**
