curl -sL | source && fisher install jorgebucaran/fisher


You can install, update, and remove plugins interactively with Fisher, taking advantage of Fish tab completion and rich syntax highlighting.

Installing plugins

Install plugins using the install command followed by the path to the repository on GitHub.

fisher install jorgebucaran/

To install from GitLab prepend to the plugin path.

To get a specific version of a plugin add an @ symbol after the plugin name followed by a tag, branch, or commit.

fisher install IlanCosman/tide@v5

You can install plugins from a local directory too.

fisher install ~/path/to/plugin

Fisher expands plugins into your Fish configuration directory by default, overwriting existing files. If you wish to change this behavior, set $fisher_path to your preferred location and put it in your function path (#640).

Listing plugins

List all the plugins that are currently installed using the list command.

$ fisher list

The list command also accepts a regular expression to filter the output.

$ fisher list \^/

Updating plugins

The update command updates one or more plugins to their latest version.

fisher update jorgebucaran/fisher

Use just fisher update to update everything.

Removing plugins

Remove installed plugins using the remove command.

fisher remove jorgebucaran/

You may want to remove everything, including Fisher.

fisher list | fisher remove

Using your fish_plugins file

Whenever you install or remove a plugin from the command line, Fisher will write down all the installed plugins to $__fish_config_dir/fish_plugins. Adding this file to your dotfiles or version control is the easiest way to share your configuration across different systems.

You can also edit this file and run fisher update to commit changes:

nano $__fish_config_dir/fish_plugins
+ PatrickF1/
- /home/jb/path/to/plugin
fisher update

That will install PatrickF1/, remove /home/jb/path/to/plugin, and update everything else.

Creating a plugin

A plugin can be any number of files in a functions, conf.d, and completions directory. Most plugins consist of a single function, or configuration snippet. This is what a typical plugin looks like.

├── completions
│   └──
├── conf.d
│   └──
└── functions

Non .fish files as well as directories inside those locations will be copied to $fisher_path under functions, conf.d, or completions respectively.

Event system

Plugins are notified as they are being installed, updated, or removed via Fish events.

--on-event functions must already be loaded when their event is emitted. Thus, you should put your event handlers in the conf.d directory.

# Defined in ponyo/conf.d/

function _ponyo_install --on-event ponyo_install
    # Set universal variables, create bindings, and other initialization logic.

function _ponyo_update --on-event ponyo_update
    # Migrate resources, print warnings, and other update logic.

function _ponyo_uninstall --on-event ponyo_uninstall
    # Erase "private" functions, variables, bindings, and other uninstall logic.

Creating a theme

A theme is just like a regular Fish plugin, except it has a .theme file in the themes directory. Themes were introduced in Fish 3.4 and work with the fish_config builtin. A theme can also have files in functions, conf.d, or completions if necessary. This is what a typical theme plugin might look like.

├── conf.d
│   └──
└── themes
    └── sosuke.theme

Using $fisher_path with themes

If you customize $fisher_path to use a directory other than $__fish_config_dir, your themes won't be available via fish_config. That's because Fish expects your themes to be in $__fish_config_dir/themes, not $fisher_path/themes. This is not yet configurable in Fish, but there is a request to add that feature.

This problem can easily be solved by symlinking Fisher's themes directory into your Fish config. First, backup any existing themes directory.

mv $__fish_config_dir/themes $__fish_config_dir/themes.bak

Then, symlink Fisher's themes directory.

ln -s $fisher_path/themes $__fish_config_dir/themes

If you want to use theme plugins and also maintain your own local themes, you can read more about how to do that here: #708.


Fisher doesn't make use of a central repository of plugins. However, that doesn't mean discovering new plugins should be hard. A great way to help people quickly find your project on GitHub is by adding a topic to your repository. We recommend using fish-plugin for this purpose.


Fisher started out in 2016 by @jorgebucaran as a shell configuration manager for Fish. We had a lot of help along the way. Oh My Fish laid the groundwork as the first popular Fish framework. @jethrokuan was particularly helpful during the first years. @PatrickF1's candid feedback has been invaluable time and again. Bootstrapping Fisher was originally @IlanCosman's idea. Thank you to all our contributors! <3
