Adding themes and plugins to Zsh

In my previous article, I defined how you can get began with Z-shell (Zsh). For some customers, essentially the most thrilling factor about Zsh is its potential to undertake new themes. It’s really easy to theme Zsh each due to the energetic group designing visuals for the shell and likewise due to the Oh My Zsh challenge, which makes it trivial to put in them.

Theming is a kind of adjustments you discover instantly, so in case you do not feel such as you modified shells whenever you put in Zsh, you may undoubtedly really feel it as soon as you’ve got adopted one of many 100+ themes bundled with Oh My Zsh. There’s much more to Oh My Zsh than simply fairly themes, although; there are additionally tons of of plugins that add options to your Z-shell surroundings.

Installing Oh My Zsh

The ohmyz.sh web site encourages you to put in the framework by working a script over the web out of your laptop. While the Oh My Zsh challenge is nearly actually reliable, it is typically ill-advised to blindly run scripts in your system. If you need to run the set up script, you possibly can obtain it, learn it, and run it after you are happy you perceive what it is doing.

If you obtain the script and skim it, it’s possible you’ll discover that set up is just a three-step course of:

1. Clone oh-my-zsh

First, clone the oh-my-zsh repository right into a listing referred to as ~/.oh-my-zsh:

% git clone http://github.com/robbyrussell/oh-my-zsh ~/.oh-my-zsh

2. Switch the config file

Next, again up your current .zshrc file and transfer the default one from the oh-my-zsh set up into its place. You can do that in a single command utilizing the -b (backup) possibility for mv, so long as your model of the mv command contains that possibility:

% mv -b 
~/.oh-my-zsh/templates/zshrc.zsh-template 
~/.zshrc

three. Edit the config

By default, Oh My Zsh’s configuration is fairly bland, so that you may need to reintegrate your customized ~/.zshrc into the .oh-my-zsh config. To do this, append your previous config to the tip of the brand new one utilizing the cat command:

% cat ~/.zshrc~ >> ~/.zshrc

To see the default configuration and find out about among the choices it gives, open ~/.zshrc in your favourite textual content editor. The file is well-commented, so it is a good way to get a good suggestion of what is doable.

For occasion, you possibly can change the placement of your .oh-my-zsh listing. At set up, it resides on the base of your property listing, however fashionable Linux conference, as outlined by the Free Desktop specification, is to position directories that reach the performance of functions within the ~/.native/share listing. You can change it in ~/.zshrc by modifying the road:

# Path to your oh-my-zsh set up.
export ZSH=$HOME/.native/share/oh-my-zsh

then transferring the listing to that location:

% mv ~/.oh-my-zsh 
$HOME/.native/share/oh-my-zsh

If you are utilizing MacOS, the specification is much less clear, however arguably essentially the most applicable place for the listing is $HOME/Library/Application Support.

Relaunching Zsh

After modifying the config, you need to relaunch your shell. Before you do this, be sure you’ve completed any in-progress config adjustments; for example, do not change the trail of .oh-my-zsh then overlook to maneuver the listing to its new location. If you do not need to relaunch your shell, you possibly can supply the config file, simply as you possibly can with Bash:

% supply ~/.zshrc
➜  .oh-my-zsh git:(grasp) ✗ 

You can ignore any warnings about lacking replace recordsdata; they are going to be resolved upon relaunch.

Changing your theme

Installing Oh My Zsh units your Z-shell theme to robbyrussell, a theme by the challenge’s maintainer. This theme’s adjustments are minimal, largely involving the colour of your immediate.

To view all of the out there themes, listing the contents of the .oh-my-zsh theme listing:

af-magic.zsh-theme
afowler.zsh-theme

[...]

To see screenshots of themes earlier than attempting them, go to the Oh My Zsh wiki. For much more themes, go to the External themes wiki web page.

Most themes are easy to arrange and use. Just change the worth of the theme identify in .zshrc and reload the config:

➜ ~ sed -i 
's/_THEME="robbyrussel"/_THEME="linuxonly"/g' 
~/.zshrc
➜ ~ supply ~/.zshrc
seth@darkstar:pts/zero->/residence/skenlon (zero) ➜

Other themes require additional configuration. For instance, to make use of the agnoster theme, you will need to first set up the Powerline font. This is an open supply font, and it is in all probability in your software program repository in case you’re working Linux. Install it with:

➜ ~ sudo dnf set up powerline-fonts

Set your theme within the config:

➜ ~ sed -i 
's/_THEME="linuxonly"/_THEME="agnoster"/g' 
~/.zshrc

after which relaunch (a easy supply will not work). Upon relaunch, you will notice the brand new theme:

Installing plugins

Over 200 plugins ship with Oh My Zsh, and you may see them by trying in .oh-my-zsh/plugins. Each plugin listing has a README file explaining what the plugin does.

Some plugins are comparatively easy. For occasion, the dnf, ubuntu, brew, and macports plugins are collections of aliases to simplify interactions with the DNF, Apt, Homebrew, and MacPorts bundle managers.

Others are extra complicated. The git plugin, energetic by default, detects whenever you’re working in a Git repository and updates your shell immediate in order that it lists the present department and even signifies whether or not there are unmerged adjustments.

To activate a plugin, add it to the plugin setting in ~/.zshrc. For instance, so as to add the dnf and move plugins, open ~/.zshrc in your favourite textual content editor:

Save your adjustments and reload your Zsh session:

% supply ~/.zshrc

The plugins are actually energetic. You can take a look at the dnf plugin through the use of one of many aliases it gives:

fop.noarch : XSL-driven print formatter

Different plugins do various things, so it’s possible you’ll need to set up just one or two at a time that can assist you be taught the brand new capabilities of your shell.

Cheating

Some Oh My Zsh plugins are fairly generic. If you have a look at a plugin that claims to be a Z-shell plugin and the code can be appropriate with Bash, then you should utilize it in your Bash shell. Some plugins require Z-shell-specific features, so this may not work with all of them. But you possibly can load plugins like dnf, ubuntu, firewalld, and others right into a Bash shell through the use of supply to load the plugin of your selection. For instance:
