zsh-syntax-highlighting zsh-syntax-highlighting
======================= =======================
An attempt at providing [Fish shell](http://www.fishshell.org) like syntax highlighting for [Zsh](http://www.zsh.org). [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 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 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 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/ cd ~/.oh-my-zsh/plugins/
git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git git clone git://github.com/nicoulaj/zsh-syntax-highlighting.git
cd zsh-syntax-highlighting cd zsh-syntax-highlighting
ln -s zsh-syntax-highlighting.zsh zsh-syntax-highlighting.plugin.zsh 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) 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 source ~/.zshrc
## References ## Tweak it
* [zsh-users mailing list thread](http://www.zsh.org/mla/users/2010/msg00692.html) 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:
* [Gist 586698](http://gist.github.com/586698) and forks
# 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).
