Prezto — Instantly Awesome Zsh
==============================

Prezto is the configuration framework for [Zsh][1]; it enriches the command line
interface environment with sane defaults, aliases, functions, auto completion,
and prompt themes.

Installation
------------

Prezto will work with any recent release of Zsh, but the minimum required
version is 4.3.11.

  1. Launch Zsh:

     ```console
     zsh
     ```

  2. Clone the repository:

     ```console
     git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"
     ```

  3. Create a new Zsh configuration by copying the Zsh configuration files
     provided:

     ```sh
     setopt EXTENDED_GLOB
     for rcfile in "${ZDOTDIR:-$HOME}"/.zprezto/runcoms/^README.md(.N); do
       ln -s "$rcfile" "${ZDOTDIR:-$HOME}/.${rcfile:t}"
     done
     ```

     Note: If you already have any of the given configuration files, `ln` will
     cause error. In simple cases you can load prezto by adding the line
     `source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh"` to the bottom of your
     `.zshrc` and keep the rest of your Zsh configuration intact. For more
     complicated setups, it is recommended that you back up your original
     configs and replace them with the provided prezto runcoms.

  4. Set Zsh as your default shell:

     ```console
     chsh -s /bin/zsh
     ```

  5. Open a new Zsh terminal window or tab.

### Troubleshooting

If you are not able to find certain commands after switching to *Prezto*,
modify the `PATH` variable in *~/.zprofile* then open a new Zsh terminal
window or tab.

Updating
--------

Run `zprezto-update` to automatically check if there is an update to zprezto.
If there are no file conflicts, zprezto and its submodules will be
automatically updated. If there are conflicts you will be instructed to go into
the `$ZPREZTODIR` directory and resolve them yourself.

To pull the latest changes and update submodules manually:

```console
cd $ZPREZTODIR
git pull
git submodule update --init --recursive
```

Usage
-----

Prezto has many features disabled by default. Read the source code and
accompanying README files to learn of what is available.

### Modules

  1. Browse */modules* to see what is available.
  2. Load the modules you need in *~/.zpreztorc* then open a new Zsh terminal
     window or tab.

### Themes

  1. For a list of themes, type `prompt -l`.
  2. To preview a theme, type `prompt -p name`.
  3. Load the theme you like in *~/.zpreztorc* then open a new Zsh terminal
     window or tab.

     ![sorin theme][2]
     Note that the 'git' module may be required for special symbols to appear,
     such as those on the right of the above image. Add `'git'` to the `pmodule`
     list (under `zstyle ':prezto:load' pmodule \` in your *~/.zpreztorc*) to
     enable this module.

### External Modules

  1. By default modules will be loaded from */modules* and */contrib*.
  2. Additional module directories can be added to the
     `:prezto:load:pmodule-dirs` setting in *~/.zpreztorc*.

     Note that module names need to be unique or they will cause an error when
     loading.

     ```sh
     zstyle ':prezto:load' pmodule-dirs $HOME/.zprezto-contrib
     ```
