Nushell <https://www.nushell.sh/> is a modern interactive shell that provides many shell features out-of-the-box, like `title` support. Our shell integration therefore focuses on Ghostty-specific features like `sudo`. We use Nushell's module system to provide a `ghostty` module containing our shell integration features. This module is automatically loaded from $XDG_DATA_DIRS/nushell/vendor/autoload/ when `nushell` shell integration is enabled. Exported module functions need to be explicitly "used" before they're available to the interactive shell environment. We do that automatically by adding `--execute "use ghostty *"` to the `nu` command line. This imports all available functions, and individual shell features are runtime-guarded by the script code (using $GHOSTTY_SHELL_FEATURES). We can consider further refining this later. When automatic shell integration is disabled, users can still manually source and enable the shell integration module: source $GHOSTTY_RESOURCES_DIR/shell-integration/nushell/vendor/autoload/ghostty.nu use ghostty * This initial work implements our TERMINFO-aware `sudo` wrapper (via the `sudo` shell feature). Support for additional features, like `ssh-env` and `ssh-terminfo`, will follow.
