Bluefin CLI

A powerful, modern CLI tool for managing shell configuration and development environment customization. Built with beautiful TUIs using Charm libraries.

✨ Features

🎨 Interactive Menu: Default TUI experience for easy navigation
✨ Bling: Toggle modern shell enhancements (eza, bat, ugrep, zoxide, atuin, starship)
📰 MOTD: Beautiful Message of the Day with system info and random tips
📦 Bundle Installer: Install curated tool bundles (ai, cli, fonts, k8s) from Universal Blue
🖼️ Wallpapers: Install desktop wallpaper collections from ublue-os/tap
🎨 Starship Themes: Browse and apply Starship prompt themes
📊 Status Command: View configuration and installed tools at a glance
🩺 Doctor: bluefin-cli doctor diagnoses setup problems with fix hints
🎨 Theme Flavors: bluefin-cli theme <flavor> pins a Catppuccin flavor (latte, frappe, macchiato, mocha) or follows your terminal with auto
⬆ Self-Update: bluefin-cli update for script installs — sha256-verified against the release checksums; package-manager installs are pointed at the right upgrade command
🏠 My Brewfile: one file describes your machine's packages — brew/cask lines plus winget/scoop/choco on Windows. bluefin-cli brewfile dump captures what's installed, add/remove edit it, install applies everything; the TUI's Install Apps → My Brewfile does all of it interactively with per-package management. Extra recipes in ~/.config/bluefin-cli/bundles/*.Brewfile appear alongside the curated bundles
📦 Profiles: bluefin-cli profile export > setup.json on one machine, profile import setup.json on another — shells, tools, and theme replayed exactly
🦕 A fully native TUI: persistent shell with breadcrumbs, fuzzy filtering (/), a ctrl+p command palette, and a dot-matrix dino running the header — plus a hidden surprise for those who find it

🚀 Installation

Status (2026-08-14): releases ship prebuilt binary assets (v0.10.6+ publishes tarballs for Linux/macOS/Windows + native deb/rpm packages), so the one-liner scripts below work. The package-manager paths that are still pending are marked individually below.

One-liner (Linux / macOS)

curl -fsSL https://raw.githubusercontent.com/tuna-os/bluefin-cli/main/install.sh | sh

Status (2026-08-14): the script downloads the binary from GitHub release assets, which are published since v0.10.6 (#141, closed).

One-liner (Windows PowerShell)

irm https://raw.githubusercontent.com/tuna-os/bluefin-cli/main/install.ps1 | iex

Then enable shell integration:

bluefin-cli shell powershell on

Status (2026-08-14): same as the Linux/macOS one-liner — the script downloads from GitHub release assets, which are published since v0.10.6 (#141, closed).

Homebrew (Linux / macOS)

The formula is published automatically by GoReleaser to the tuna-os/homebrew-tap tap on every release (#15):

brew tap tuna-os/tap
brew install bluefin-cli

Status (2026-08-14): the bluefin-cli formula has not been published by the release pipeline yet — only corral-vm.rb ships in the tuna-os tap (see #141). Until it appears, use ublue-os/homebrew-experimental-tap below.

It is also available from ublue-os/homebrew-experimental-tap, synced from the source-build formula in contrib/homebrew/bluefin-cli.rb:

brew tap ublue-os/homebrew-experimental-tap
brew install bluefin-cli

Winget (Windows)

winget install --id Hanthor.BluefinCLI --exact

Status (2026-08-14): Hanthor.BluefinCLI v0.8.1 is published in the winget repository (microsoft/winget-pkgs#407090, merged 08-14) but predates the current v0.10.6 release line — installable, though not yet current (#141, closed — release publishing works; a newer manifest submission is pending).

Chocolatey (Windows)

choco install bluefin-cli

Status (2026-08-14): no bluefin-cli package has been published to the Chocolatey community repository yet — not available (#141, closed — release publishing now works, the Choco manifest is still pending).

Scoop (Windows)

scoop bucket add tuna-os https://github.com/tuna-os/scoop-bucket
scoop install bluefin-cli

Status (2026-08-14): tuna-os/scoop-bucket has no manifests yet — the manifest is published by the release pipeline and is currently pending (#141, closed — release publishing now works, the Scoop manifest is still pending).

deb / rpm (Debian, Ubuntu, Fedora, openSUSE…)

Releases ship native packages (nfpm) since v0.10.6 — grab the one for your

distro from the latest release:

# Debian/Ubuntu
sudo dpkg -i bluefin-cli_<version>_linux_amd64.deb
# Fedora & friends
sudo rpm -i bluefin-cli_<version>_linux_amd64.rpm

AUR (Arch)

yay -S bluefin-cli-bin

Status (2026-08-14): no bluefin-cli-bin package exists in the AUR yet — not available (#141, closed).

Go Install

go install github.com/tuna-os/bluefin-cli@latest

Build from Source (Any OS)

Prerequisites:

Go 1.25 or later

git clone https://github.com/tuna-os/bluefin-cli.git
cd bluefin-cli
go build -o bluefin-cli .

On Windows, use go build -o bluefin-cli.exe ..

Maintainers: package publishing (Homebrew tap, Winget, Scoop) is automated by GoReleaser on release; .github/workflows/winget.yml is a manual fallback for re-submitting a Winget version.

Scoop publishing requires the SCOOP_BUCKET_TOKEN repository secret (a fine-grained PAT with write access to tuna-os/scoop-bucket), without which the Scoop manifest upload step is safely skipped during release workflows. See docs/release-publishing.md for details.

Homebrew tap publishing requires the HOMEBREW_TAP_TOKEN repository secret (a fine-grained PAT with write access to tuna-os/homebrew-tap), without which the formula upload step is safely skipped during release workflows. See docs/release-publishing.md for details.

Homebrew release process: on every tagged release GoReleaser publishes the binary formula to tuna-os/homebrew-tap (requires the HOMEBREW_TAP_TOKEN secret). External taps that build from source, such as ublue-os/homebrew-experimental-tap, must be synced manually — bump url and sha256 in contrib/homebrew/bluefin-cli.rb and open a PR in that tap.

bluefin-cli install wallpapers bluefin-wallpapers --non-interactive --apply-theme --theme Bluefin --enable-mode-sync --enable-auto-dark-light --trigger-source polling

bluefin-cli install wallpapers bluefin-wallpapers --non-interactive --enable-mode-sync --trigger-source startup

bluefin-cli install wallpapers cleanup --all

Non-interactive wallpaper flags:

--non-interactive: Skip prompts and use provided flags.
--yes: Shortcut for --non-interactive --apply-theme --enable-mode-sync --enable-auto-dark-light.
--apply-theme: Apply a Windows theme after registration (WSL only).

autodarkmode notes:

Bluefin CLI ensures %LOCALAPPDATA%\\BluefinCLI\\set-light-mode.ps1 and %LOCALAPPDATA%\\BluefinCLI\\set-dark-mode.ps1 exist.
In Auto Dark Mode, point light/dark custom script hooks to those two scripts.

Starship Themes

You can change the appearance of your prompt. Browse and apply Starship preset themes:

bluefin-cli starship theme

Install Starship if not already present:

bluefin-cli starship install

📚 Inspiration

This project consolidates and modernizes functionality from:

ublue-bling: Shell aliases and tool initialization scripts
bluefin-cli (cask): Homebrew package management and MOTD
ujust recipes: Task runner and development environment helpers

🛠️ Development

Prerequisites

Go 1.25.8 or later (the CI jobs currently validate with Go 1.27)

just test

# Run the complete Go test suite locally

go test ./...

# Run the same race-enabled suite used by CI

go test -tags extra -race ./...

Interactive Development

Launch shells with bling pre-configured:

just bash   # Test in bash
just zsh    # Test in zsh
just fish   # Test in fish

Dependencies

This project uses:
