prelude-加强版的Emacs 24

Prelude is an enhanced Emacs 24 distribution that should make your experience with Emacs both more pleasant and more powerful. 


Prelude is an Emacs distribution that aims to enhance the default Emacs experience. Prelude alters a lot of the default settings, bundles a plethora of additional packages and adds its own core library to the mix. The final product offers an easy to use Emacs configuration for Emacs newcomers and lots of additional power for Emacs power users.
Prelude is compatible ONLY with GNU Emacs 24.x. In general you're advised to always run Prelude with the latest Emacs - currently 24.3.

Fast Forward

Assuming you're using an Unix-like OS (*BSD, GNU/Linux, OS X, Solaris, etc), you already have Emacs 24 installed, as well as git & curl you can skip the whole manual and just type in your favorite shell the following command:

curl -L http://git.io/epre | sh

You can now power up your Emacs, sit back and enjoy Prelude, forgetting about the rest of this manual.
There are two environment variables you can use to control the source repository and the installation directory. To change the installation directory:

export PRELUDE_INSTALL_DIR="$HOME/.emacs.d" && curl -L https://github.com/bbatsov/prelude/raw/master/utils/installer.sh | sh

To change the source repository:

export PRELUDE_URL="https://github.com/yourname/prelude.git" && curl -L https://github.com/bbatsov/prelude/raw/master/utils/installer.sh | sh

Note that the installer will back up any existing .emacs file or .emacs.d since it will unpack Prelude's code in .emacs.d. If you're doing a manual install make sure you don't have a .emacs file or back up your existing .emacs.d directory manually.
Don't forget to adjust your prelude-modules.el file once the installation is done. By default most of the modules that ship with Prelude are not loaded.

Installing Emacs 24

Obviously to use the Emacs Prelude you have to install Emacs 24 first. Have a look at the WikEmacs articles on installing Emacs.

Installation

Automated

You can install Emacs Prelude via the command line with either curl or wget. Naturally git is also required.

Via Curl

If you're using curl type the following command:

curl -L https://github.com/bbatsov/prelude/raw/master/utils/installer.sh | sh

Via Wget

If you're using wget type:

wget --no-check-certificate https://github.com/bbatsov/prelude/raw/master/utils/installer.sh -O - | sh

Manual

git clone git://github.com/bbatsov/prelude.git path/to/local/repo
ln -s path/to/local/repo ~/.emacs.d
cd ~/.emacs.d

You'd do well to replace ~/.emacs.d with the value of user-emacs-directory for your OS. You can check the value by doing C-h v user-emacs-directory inside Emacs.

Updating Prelude

Manual update

The update procedure is fairly straightforward and consists of 3 steps:

Update all bundled packages

Just run M-x package-list-packages RET U x.

Update Prelude's code

cd path/to/prelude/installation
git pull

The path/to/prelude/installation is usually ~/.emacs.d (at least on Unix systems).

Restart Prelude

It's generally a good idea to stop Emacs after you do the update. The next time Prelude starts it will install any new dependencies (if there are such).

Automatic update

Simply run M-x prelude-update from Emacs itself and restart Emacs afterwards.

Enabling additional modules

By default most of the modules that ship with Prelude are not loaded. For more information on the functionality provided by these modules visit the docs.
