Installation

curl -sL https://git.io/fisher | source && fisher install jorgebucaran/fisher

Automatic install

If you want to automatically install fisher when it is not present, you can add the following at the top of your ~/.config/fish/config.fish. If fish_plugins is present is readed first.

if not functions -q fisher; curl -sL https://git.io/fisher | source && fisher update || fisher install jorgebucaran/fisher; end

Quickstart

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/nvm.fish

To install from GitLab prepend gitlab.com/ 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
jorgebucaran/fisher
ilancosman/tide@v5
jorgebucaran/nvm.fish
/home/jb/path/to/plugin

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

$ fisher list \^/
/home/jb/path/to/plugin

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/nvm.fish

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

jorgebucaran/fisher
ilancosman/tide@v5
jorgebucaran/nvm.fish
+ PatrickF1/fzf.fish
- /home/jb/path/to/plugin

fisher update

That will install PatrickF1/fzf.fish, 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.

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

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/ponyo.fish

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

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

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

Discoverability

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.

Acknowledgments

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
