A lightweight terminal-based clipboard history manager, built with Go and the Bubble Tea TUI framework.

Features

• 📋 Automatic Clipboard Monitoring - Continuously tracks clipboard changes in real-time
• 🕒 Persistent History - Saves clipboard history to disk across sessions
• 🎯 Duplicate Detection - Automatically filters out duplicate entries using SHA-256 hashing
• ⌨️ Keyboard Navigation - Navigate through history with vim-style keybindings
• 📱 Clean Terminal UI - Beautiful, responsive interface that fits your workflow
• 🔄 Instant Copy - Copy any historical item back to clipboard with a single keypress

Demo

Installation

Prerequisites

• Go 1.20 or later
• MacOS
• Linux with X11 or Wayland (uses xclip or wl-clipboard)

Install from source

git clone https://github.com/bvdwalt/clippy.git
cd clippy
go build -o clippy ./cmd/clippy
sudo mv clippy /usr/local/bin/

Install dependencies (if needed)

For X11:

sudo apt install xclip  # Ubuntu/Debian
sudo dnf install xclip  # Fedora

For Wayland:

sudo apt install wl-clipboard  # Ubuntu/Debian
sudo dnf install wl-clipboard  # Fedora

Usage

Start the clipboard history manager:

clippy

Keybindings

Key	Action
↑ / k	Navigate up through history
↓ / j	Navigate down through history
Enter / c	Copy selected item to clipboard
d	Delete selected item from history
/	Enter search mode
r	Refresh/clear search results
Esc	Exit search mode (when in search)
q / Ctrl+C	Quit application

Search Mode

When you press /, you'll enter search mode where you can:

• Type to filter clipboard history using fuzzy search (similar to fzf)
• Press Enter to apply the search filter
• Press Esc to cancel and return to normal view

How It Works

Clippy monitors your system clipboard every 2 seconds and automatically captures any new content. Each clipboard entry is:

1. Hashed using SHA-256 to detect duplicates
2. Timestamped for chronological organization
3. Persisted to history.json in the current directory
4. Displayed in a scrollable terminal interface

The application shows a preview of each clipboard entry (truncated to 60 characters) and replaces newlines with spaces for clean display.
