Bluefin CLI

A strong, modern CLI tool that manages your shell configuration and the look of your development environment. Its TUIs use the Charm libraries.

✨ Features

• 🎨 Interactive Menu: Default TUI experience for easy navigation
• ✨ Shell Experience: Turn on modern tools for your shell (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. For a package-manager install, it tells you the correct upgrade command
• 🏠 My Brewfile: one file describes your machine's packages — brew/cask lines plus winget/scoop/choco on Windows. bluefin-cli brewfile dump records the installed packages. add/remove edit that file, and install applies all of it. The TUI does the same from Install Apps → My Brewfile, one package at a time. 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: a persistent shell with breadcrumbs, a fuzzy filter (/), a ctrl+p command palette, and a dot-matrix dino in the header. It also hides a surprise.

🚀 Installation

Status (2026-08-14): each release ships prebuilt binary assets. Since v0.10.6 that includes tarballs for Linux, macOS and Windows, plus native deb and rpm packages, so the one-liner scripts below work. A note marks each package-manager path that is not ready yet.

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 1.26.0 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: semantic-release gives a version to each qualified merge to main, then calls GoReleaser to send the release assets to the package channels. .github/workflows/winget.yml is a manual fallback, to submit a Winget version again.

A Scoop release needs 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.

A Homebrew tap release needs 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: when semantic-release determines that a merge to main warrants a release, it invokes GoReleaser, which 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.

✨ Shell Experience

Bluefin CLI includes a "Shell Experience" module (formerly "bling") that configures your shell with modern tools and aliases.

To enable the shell experience:

bluefin-cli shell bash on
bluefin-cli shell zsh on
bluefin-cli shell fish on
bluefin-cli shell ash on      # busybox ash (Alpine, postmarketOS)
bluefin-cli shell nu on       # Nushell
bluefin-cli shell powershell on

Or use the interactive menu: bluefin-cli menu -> "Shell Experience".

Two shells need a word of explanation:

• ash has no rc file by convention. An interactive ash reads the file that $ENV names. Thus shell ash on writes ~/.ashrc, then exports ENV from ~/.profile so that ash reads it. atuin, starship and carapace have no ash target, so bluefin-cli omits them there. The other tools work as usual.
• Nushell cannot evaluate a string. Thus shell nu on writes the init script to ~/.config/nushell/bluefin-cli.nu, and config.nu reads it from there. Run bluefin-cli shell nu on again after you change your tool configuration, to make a new copy of that script.

Features:

• eza: Modern replacement for ls
• bat: Syntax color for cat
• ugrep: Faster grep
• zoxide: Smarter cd
• atuin: Shell history sync
• starship: Cross-shell prompt
• uutils: Rust rewrite of coreutils

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).
• --theme <name>: Theme to apply in non-interactive mode (Bluefin, Aurora, Bazzite).
• --enable-mode-sync: Enable day/night wallpaper sync task.
• --enable-auto-dark-light: Turn on the 6 AM and 6 PM light/dark tasks (needs --enable-mode-sync).
• --trigger-source <source>: Mode-sync trigger source (polling, startup, autodarkmode).

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

🔧 What Gets Configured

Shell Experience Tools

The shell command configures these modern CLI tools:

• eza: Modern replacement for ls with icons and colors

• zoxide: Smarter cd command that learns your habits
• atuin: Magical shell history with sync and search (optional)
• starship: Fast, customizable prompt for any shell
• ugrep: Ultra-fast grep alternative (optional)

Shell Aliases

When the shell experience is enabled in your shell:

ll      # eza -l --icons=auto --group-directories-first
ls      # eza
cat     # bat --style=plain --pager=never
grep    # ugrep (if installed)

Building

just build

just build creates both variants:

• bluefin-cli: the standard CLI
• bluefin-cli-plus: the standard CLI plus features selected by the extra build tag, including wallpapers, fonts, and sunset automation

Testing

# Run the integration suite in a container

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 the shell experience pre-configured:

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

Dependencies

This project uses:
