# 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**.
|
|
|
|
|
|
|
|
|
|
01. Launch Zsh:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
zsh
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
02. Clone the repository:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
git clone --recursive https://github.com/sorin-ionescu/prezto.git "${ZDOTDIR:-$HOME}/.zprezto"
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
03. Create a new Zsh configuration by copying the Zsh configuration files
|
|
|
|
|
provided:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
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` in
|
|
|
|
|
the above operation will cause an error. In simple cases, you can load
|
|
|
|
|
Prezto by adding the line `source "${ZDOTDIR:-$HOME}/.zprezto/init.zsh"` to
|
|
|
|
|
the bottom of your *${ZDOTDIR:-$HOME}/.zshrc* and keep the rest of your Zsh
|
|
|
|
|
configuration intact. For more complicated setups, we recommend that you
|
|
|
|
|
back up your original configs and replace them with the provided Prezto
|
|
|
|
|
*runcoms*.
|
|
|
|
|
|
|
|
|
|
04. Set Zsh as your default shell:
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
chsh -s /bin/zsh
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
05. 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 *${ZDOTDIR:-$HOME}/.zprofile* then open a new Zsh
|
|
|
|
|
terminal window or tab.
|
|
|
|
|
|
|
|
|
|
## Updating
|
|
|
|
|
|
|
|
|
|
Run `zprezto-update` to automatically check if there is an update to Prezto.
|
|
|
|
|
If there are no file conflicts, Prezto 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 $ZPREZTODIR
|
|
|
|
|
git pull
|
|
|
|
|
git submodule sync --recursive
|
|
|
|
|
git submodule update --init --recursive
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
|
|
Prezto has many features disabled by default. Read the source code and the
|
|
|
|
|
accompanying README files to learn about what is available.
|
|
|
|
|
|
|
|
|
|
### Modules
|
|
|
|
|
|
|
|
|
|
01. Browse */modules* to see what is available.
|
|
|
|
|
02. Load the modules you need in *${ZDOTDIR:-$HOME}/.zpreztorc* then open a new
|
|
|
|
|
Zsh terminal window or tab.
|
|
|
|
|
|
|
|
|
|
### Themes
|
|
|
|
|
|
|
|
|
|
01. For a list of themes, type `prompt -l`.
|
|
|
|
|
02. To preview a theme, type `prompt -p name`.
|
|
|
|
|
03. Load the theme you like in *${ZDOTDIR:-$HOME}/.zpreztorc* then open a new
|
|
|
|
|
Zsh terminal window or tab.
|
|
|
|
|
|
|
|
|
|
![sorin theme][2]
|
|
|
|
|
Note that the *git* module may be required for special symbols to appear,
|
|
|
|
|
such as those on the right of the above image. Add `'git'` to the `pmodule`
|
|
|
|
|
list (under `zstyle ':prezto:load' pmodule \` in your
|
|
|
|
|
*${ZDOTDIR:-$HOME}/.zpreztorc*) to enable this module.
|
|
|
|
|
|
|
|
|
|
### External Modules
|
|
|
|
|
|
|
|
|
|
01. By default modules will be loaded from */modules* and */contrib*.
|
|
|
|
|
02. Additional module directories can be added to the
|
|
|
|
|
`:prezto:load:pmodule-dirs` setting in *${ZDOTDIR:-$HOME}/.zpreztorc*.
|
|
|
|
|
|
|
|
|
|
Note that module names need to be unique or they will cause an error when
|
|
|
|
|
loading.
|
|
|
|
|
|
|
|
|
|
```console
|
|
|
|
|
zstyle ':prezto:load' pmodule-dirs $HOME/.zprezto-contrib
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
