=======================
|
||||
|
||||
An attempt at providing [Fish shell](http://www.fishshell.org) like syntax highlighting for [Zsh](http://www.zsh.org).

|
||||
## Usage
|
||||
## Try it
|
||||
|
||||
Here is a one-liner to try it without installing or modifying anything:
|
||||
|
||||
wget --no-check-certificate --output-document=/tmp/zsh-syntax-highlighting.zsh https://github.com/nicoulaj/zsh-syntax-highlighting/raw/master/zsh-syntax-highlighting.zsh && . /tmp/zsh-syntax-highlighting.zsh
|
||||
|
||||
|
||||
### From your ~/.zshrc
|
||||
## Install it
|
||||
|
||||
Download the script or clone this repository:
|
||||
|
||||
### In your ~/.zshrc
|
||||
|
||||
* Download the script or clone this repository:
|
||||
|
||||
git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git
|
||||
|
||||
Update your `~/.zshrc` so that the script is sourced:
|
||||
* Source the script at the end of `~/.zshrc`:
|
||||
|
||||
source /path/to/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
|
||||
|
||||
Re-open your terminal, or just reload it to take changes into account:
|
||||
* Source `~/.zshrc` to take changes into account:
|
||||
|
||||
source ~/.zshrc
|
||||
|
||||
|
||||
### With [oh-my-zsh](http://github.com/robbyrussell/oh-my-zsh)
|
||||
### With oh-my-zsh
|
||||
|
||||
Download the script or clone this repository as a oh-my-zsh plugin:
|
||||
* Download the script or clone this repository in [oh-my-zsh](http://github.com/robbyrussell/oh-my-zsh) plugins directory:
|
||||
|
||||
cd ~/.oh-my-zsh/plugins/
|
||||
git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git
|
||||
cd zsh-syntax-highlighting
|
||||
ln -s zsh-syntax-highlighting.zsh zsh-syntax-highlighting.plugin.zsh
|
||||
|
||||
Update your `~/.zshrc` so that the script is sourced:
|
||||
* Activate the plugin in `~/.zshrc`
|
||||
|
||||
plugins=(zsh-syntax-highlighting)
|
||||
|
||||
Re-open your terminal, or just reload it to take changes into account:
|
||||
* Source `~/.zshrc` to take changes into account:
|
||||
|
||||
source ~/.zshrc
|
||||

Optionally, you can override the default styles used for highlighting. The styles are declared in the [`ZSH_HIGHLIGHT_STYLES` array](https://github.com/nicoulaj/zsh-syntax-highlighting/blob/master/zsh-syntax-highlighting.zsh#L9). You can override styles this way:
|
||||
|
||||
# To differenciate aliases from other command types
|
||||
ZSH_HIGHLIGHT_STYLES[alias]='fg=magenta,bold'
|
||||
|
||||
# To have paths colored instead of underlined
|
||||
ZSH_HIGHLIGHT_STYLES[path]='fg=cyan'
|
||||
|
||||
# To disable highlighting of globbing expressions
|
||||
ZSH_HIGHLIGHT_STYLES[globbing]='none'
|
||||
|
||||
This must be done **after** the script is sourced, otherwise your styles will be overwritten. The syntax for declaring styles is [documented here](http://zsh.sourceforge.net/Doc/Release/Zsh-Line-Editor.html#SEC135).
