`. 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 ``` ## 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.** # Quotes [Quote][quote01] by [ashnur](https://github.com/ashnur): «I feel that spacemacs is an aircraft carrier and I am playing table tennis on the deck as a freerider.» [Quote][quote02] by [deuill](https://github.com/deuill): «I LOVE SPACEMACS AND MAGIT That is all» # Contributions Spacemacs is a community-driven project, it needs _you_ to keep it up to date and to propose great and useful configurations for all the things!
