Creating

Package names may only contain lowercase letters and hyphens to separate words. To scaffold out a new package:

$ omf new pkg my_package

my_package/
  README.md
  my_package.fish
  completions/my_package.fish

Use omf new theme my_theme for themes.

Please provide auto completion for your utilities if applicable and describe how your package works in the README.md.

my_package.fish defines a single function:

function my_package -d "My package"
end

Bear in mind that fish lacks a private scope so consider the following options to avoid polluting the global namespace:

• Prefix functions: my_package_my_func.
• Using blocks.

Submitting

Oh My Fish keeps a registry of packages under $OMF_PATH/db/.

To create a new entry run:

omf submit pkg/my_package .../my_package.git

Similarly for themes use:

omf submit theme/my_theme .../my_theme.git

This will add a new entry to your local copy of the registry. Please send us a PR to update the global registry.

Initialization

If you want to be notified when your package loads, declare the following function in your my_package.fish:

function init -a path --on-event init_mypkg
end

Use this event to modify the environment, load resources, autoload functions, etc. If your package does not export any functions, you can still use this event to add functionality to your package.

Uninstall

Oh My Fish emits uninstall_<pkg> events before a package is removed via omf remove <pkg>. Subscribers can use the event to clean up custom resources, etc.

function uninstall --on-event uninstall_pkg
end
