Fish integration

Pacman

• Fish keybinding are installed at /usr/share/fish/vendor_functions.d/fzf_key_bindings.fish

# ~/.config/fish/functions/fish_user_key_bindings.fish
function fish_user_key_bindings
    fzf_key_bindings # enable key binding
end

Homebrew

• On Homebrew the key bindings are not automatically added to vendor_functions.d. It must be done manually

mkdir $__fish_user_data_dir/vendor_functions.d
ln -sf $(brew --prefix)/opt/fzf/shell/key-bindings.fish $__fish_user_data_dir/vendor_functions.d/key-bindings.fish

• Or simply source it in the config

source $(brew --prefix fzf)/shell/key-bindings.fish
