zellij-nvim-nav-plugin

This Zellij plugin is intended to be used in conjunction with zellij-nav.nvim as an alternative to zellij-autolock (which served as a valuable reference during the development of this plugin).

The theory of operation is simple: Ctrl-{hjkl} (or whatever keys you want to use) are bound to the "MessagePlugin" action, which send messages which this plugin listens for. If the currently selected pane is running neovim or vim, the plugin sends a specified key code to the pane, otherwise it moves focus in the specified direction.

The plugin supports both single-byte and multi-byte key sequences. Single-byte sequences are used for control key combinations (e.g., Ctrl+h = 8), while multi-byte sequences are used for Alt key combinations (e.g., Alt+h = ESC h = 27,104). The payload field accepts comma-separated byte values. You can refer to ASCII table to find the byte values for the keys you want to use.

Example Configuration

plugins {
    ...
    nvim-nav location="file:/home/youruser/some_dir/zellij-nvim-nav-plugin.wasm"
}

load_plugins {
    nvim-nav
}

    shared_except "scroll" {
        bind "Alt left" { MoveFocusOrTab "left"; }
        bind "Alt down" { MoveFocus "down"; }
        bind "Alt up" { MoveFocus "up"; }
        bind "Alt right" { MoveFocusOrTab "right"; }

        // Single-byte payloads for Ctrl key combinations
        bind "Ctrl h" { MessagePlugin { name "nvim_nav_left"; payload "8"; }; }
        bind "Ctrl j" { MessagePlugin { name "nvim_nav_down"; payload "10"; }; }
        bind "Ctrl k" { MessagePlugin { name "nvim_nav_up"; payload "11"; }; }
        bind "Ctrl l" { MessagePlugin { name "nvim_nav_right"; payload "12"; }; }

        // Use the _tab variants to navigate between panes and switch tabs when at the edge
        bind "Ctrl h" { MessagePlugin { name "nvim_nav_left_tab"; payload "8"; }; }
        bind "Ctrl l" { MessagePlugin { name "nvim_nav_right_tab"; payload "12"; }; }

        // Multi-byte payloads for Alt key combinations (ESC + key)
        bind "Alt h" { MessagePlugin { name "nvim_nav_left"; payload "27,104"; }; }
        bind "Alt j" { MessagePlugin { name "nvim_nav_down"; payload "27,106"; }; }
        bind "Alt k" { MessagePlugin { name "nvim_nav_up"; payload "27,107"; }; }
        bind "Alt l" { MessagePlugin { name "nvim_nav_right"; payload "27,108"; }; }
    }
