I created (supported by ChatGPT) this script to automate the installation and setup of the Fish shell, the Fisher plugin manager, and a curated set of plugins.

The script detects your OS/package manager, installs Fish (if needed), ensures Fisher is present, installs/updates plugins, and can optionally set Fish as your default shell.

A simple one liner does all the heavy lifting and is perfect for setting up a new terminal enviroment.

Features

OS detection for common package managers (apt, dnf, pacman, zypper, brew).
Installs Fish if missing; skips if already installed.
Installs Fisher if missing; skips if already installed.
Installs/updates plugins (listed below).
Optional update checks for Fish and plugins.
Optional default shell change via final prompt.

Supported Platforms (via package manager)

Debian/Ubuntu and derivatives — apt
Fedora — dnf
Arch/Manjaro — pacman
openSUSE — zypper
macOS — brew (requires Homebrew pre-installed)

If your distro isn’t listed, you can still run Fish/Fisher manually, then re-run the installer for plugin setup.

Requirements

Internet connectivity
curl or wget
sudo privileges for package installation

Quick Start

Run directly from your repository (replace URL with your host/path):

curl -fsSL https://your-domain-or-gitea-instance/fishing_tackle/raw/branch/main/cast.sh | bash

The script will:

Detect your OS and package manager.
Install Fish (if absent).
Install Fisher (if absent).
Install/update the configured plugins.
Prompt to set Fish as your default shell.

Plugins Installed

Fisher (manager): https://github.com/jorgebucaran/fisher
nvm.fish (Node versions): https://github.com/jorgebucaran/nvm.fish
fzf.fish (fuzzy finder integration): https://github.com/PatrickF1/fzf.fish
tide (prompt/theme): https://github.com/IlanCosman/tide
fish-abbreviation-tips: https://github.com/meaningful-ooo/fish-abbreviation-tips

You can customize the plugin list by editing the array/list inside the script before running it.

Typical Output (abridged)

✓ Detected debian (apt)
✓ Fish already installed
• Checking Fish updates…
✓ Skipped update check
✓ Fisher already present
✓ All requested plugins already installed
? Set Fish as your default shell now? (y/N)

Troubleshooting

Command not found (curl/wget): Install curl or wget with your package manager.
Permission denied: Re-run with a user that has sudo privileges.
Terminal still using old shell: Log out/in or run chsh -s /usr/bin/fish (path may vary; the script offers to do this).
