Tech Stack

• Runtime: Bun
• Framework: SolidJS
• TUI Engine: OpenTUI
• Terminal Emulator: ghostty-opentui
• PTY: node-pty (via spawn-pty)

Getting Started

Prerequisites

• Bun runtime installed on your system.
• A terminal that supports TUI applications (xterm-256color recommended).

Quick Start (No Install)

Run tuidoscope instantly without installing:

bunx tuidoscope

Installation

Install globally:

bun install -g tuidoscope

Then run from anywhere:

tuidoscope

Development

Clone the repository and install dependencies:

git clone https://github.com/shuv1337/tuidoscope.git
cd tuidoscope
bun install

Start the application in development mode:

bun dev

Build for production:

bun run build

Run typechecks:

bun run typecheck

Configuration

Tuidoscope looks for a configuration file at ~/.config/tuidoscope/tuidoscope.yaml. It also supports a local tuidoscope.yaml in the current working directory for project-specific setups.

Keyboard Shortcuts

Tuidoscope uses a simple two-mode system:

• Ctrl+A - Toggle between TABS and TERMINAL mode
• Double-tap Ctrl+A - Send Ctrl+A to the terminal (useful for nested tmux/screen)

TABS Mode (single keystrokes):

| Key | Action | |-----|--------| | j / k | Navigate down/up in tab list | | gg | Jump to first tab | | G | Jump to last tab | | Enter | Select/start app | | Space | Open command palette | | t | Add new tab | | e | Edit selected app | | x | Stop selected app | | r | Restart selected app | | K | Kill all running apps | | q | Quit tuidoscope |

TERMINAL Mode: All keystrokes pass through to the embedded terminal.

Theme Customization

Default theme is Night Owl. Customize in your tuidoscope.yaml:

theme:
  primary: "#82aaff"      # Blue - selections
  background: "#011627"   # Deep dark blue
  foreground: "#d6deeb"   # Light text
  accent: "#7fdbca"       # Cyan - active indicators
  muted: "#637777"        # Gray - inactive elements

Acknowledgments

This project is built directly on top of:

• OpenTUI - Provides the declarative component model and rendering engine for the entire interface.
• ghostty-opentui - Enables high-performance, embedded terminal sessions within the application.

Huge thanks to both for making this possible.
