termtap 0.13.0

Daemon-based tmux pane manager with learning patterns

termtap

Execute commands in tmux panes with intelligent state detection via pattern learning.

Features

• 🤖 Pattern Learning - Teach termtap process states (ready/busy) interactively
• 🎯 Smart Execution - Commands wait for processes to be ready before sending
• 🖥️ Companion UI - Visual pattern editor and queue management
• 📡 Daemon Architecture - Background process with RPC communication
• 🔌 MCP Support - Tools and resources for Claude/LLMs
• 📦 Terminal Emulation - Precise output capture with tmux streaming

Prerequisites

Required system dependencies:

• tmux - Terminal multiplexer
• gum - Interactive terminal UI components (for pattern editing)

# macOS
brew install tmux gum

# Arch Linux
sudo pacman -S tmux gum

# Ubuntu/Debian
sudo apt install tmux
# For gum: https://github.com/charmbracelet/gum#installation

Installation

# Install via uv tool (recommended)
uv tool install termtap

# Or with pipx
pipx install termtap

# Update to latest
uv tool upgrade termtap

Quick Start

1. Start Daemon

termtap daemon start

2. Launch Companion UI (optional but recommended)

termtap companion

The companion provides:

• Pattern editor with live preview
• Queue viewer for pending actions
• Pane selector for interactive workflows

3. Run REPL

termtap

4. Execute Commands

>>> execute("python3")
# First time: Companion asks if process is ready
# You teach the pattern once, termtap learns it
>>> pane()  # View output

MCP Setup for Claude

# Quick setup with Claude CLI
claude mcp add termtap -- termtap --mcp

# Or manually edit ~/Library/Application Support/Claude/claude_desktop_config.json:
{
  "mcpServers": {
    "termtap": {
      "command": "termtap",
      "args": ["--mcp"]
    }
  }
}

Commands

Command	Description
execute(command, target=None)	Run command in tmux pane, wait for ready state
pane(target=None, offset=0, limit=100)	Read pane output with pagination
ls(filter=None)	List tmux sessions
interrupt(target=None)	Send Ctrl+C to pane
send_keystrokes(keys, target=None)	Send raw keystrokes (for interactive programs)
debug(code)	Inspect daemon state (Python expressions)

Pattern Learning Workflow

First Time Execution

>>> execute("python3")
# Companion shows: "Is this process ready? (y/n)"
# You press 'y' and mark the pattern: ">>> "

Pattern Storage

Patterns are saved to ~/.termtap/patterns.json:

{
  "python": {
    "ready": [">>> ", "\\.\\.\\. "]
  }
}

Subsequent Executions

>>> execute("print('hello')")
# Automatically waits for ">>> " pattern
# Executes immediately when ready

Architecture

Components

• Daemon (termtap daemon) - Background process managing pane state
• Client - RPC client in REPL/MCP mode
• Companion (termtap companion) - Textual UI for pattern management
• Terminal Emulator - SlimScreen with pyte for output capture

Action Lifecycle

1. SELECTING_PANE - Choose target pane (if not specified)
2. READY_CHECK - Check if process matches learned patterns
3. WATCHING - Command sent, waiting for completion
4. COMPLETED - Process returned to ready state

Pattern Matching

Process Output          Pattern           State
----------------       --------          -------
>>> _                  >>> $             ready
...                    \.\.\. $          ready
Executing...           (any)             busy

Development

# Clone repository
git clone https://github.com/angelsen/tap-tools
cd tap-tools/packages/termtap

# Install for development
uv sync

# Run checks
basedpyright          # Type checking
ruff check --fix      # Linting

# Run development version
uv run termtap

# Stop daemon
termtap daemon stop

Troubleshooting

Daemon not responding

termtap daemon status   # Check daemon state
termtap daemon stop     # Stop daemon
termtap daemon start    # Restart

Pattern not matching

termtap companion       # Open companion UI
# Navigate to Patterns → Edit pattern → Test with preview

Stuck in READY_CHECK

• Open companion UI
• Queue tab shows pending actions
• Mark pattern as ready/busy or cancel action
