+# Copilot Instructions for NiimPrintX
+
+## Project Overview
+NiimPrintX is a Python library for interfacing with NiimBot label printers via Bluetooth. It provides both CLI and GUI interfaces for designing and printing labels.
+
+## Requirements
+- Python 3.12 or later
+- ImageMagick library
+- Poetry for dependency management
+
+## Setup for Testing
+
+### 1. Install System Dependencies
+
+**Linux (Ubuntu/Debian):**
+```bash
+sudo apt-get update
+sudo apt-get install -y imagemagick libmagickwand-dev python3-tk xvfb libcairo2-dev pkg-config
+```
+
+**macOS:**
+```bash
+brew install libffi glib gobject-introspection cairo pkg-config imagemagick
+export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
+export LDFLAGS="-L/usr/local/opt/libffi/lib"
+export CFLAGS="-I/usr/local/opt/libffi/include"
+```
+
+### 2. Install Python Dependencies
+
+```bash
+# Using pip (Linux/CI)
+pip install -r requirements-ci.txt
+
+# Using pip (macOS - includes pyobjc packages)
+pip install -r requirements.txt
+
+# Or using Poetry (recommended)
+python -m venv venv
+poetry install
+```
+
+**Note:** `requirements.txt` includes macOS-specific packages (pyobjc-*) which will fail on Linux. Use `requirements-ci.txt` for Linux/CI environments.
+
+### 3. Running the Application
+
+**GUI Application:**
+```bash
+python -m NiimPrintX.ui
+```
+
+**CLI Application:**
+```bash
+# Print command
+python -m NiimPrintX.cli print -m d110 -d 3 -n 1 -r 90 -i path/to/image.png
+
+# Info command
+python -m NiimPrintX.cli info -m d110
+```
+
+## Testing Guidelines
+
+### UI Testing (Headless Environment)
+
+For GUI testing in CI/CD or headless environments:
+
+```bash
+# Start virtual display
+Xvfb :99 -screen 0 1024x768x24 &
+export DISPLAY=:99
+
+# Run the UI
+python -m NiimPrintX.ui
+```
+
+### Linting
+
+```bash
+# Install flake8
+pip install flake8
+
+# Run linter (critical errors only)
+flake8 . --count --select=E9,F63,F7,F82 --show-source --statistics
+
+# Run full lint (warnings as info)
+flake8 . --count --exit-zero --max-complexity=10 --max-line-length=127 --statistics
+```
+
+### Security Scanning
+
+Use CodeQL for security analysis:
+```bash
+# CodeQL analysis is configured in GitHub Actions
+# Check .github/workflows/python-app.yml
+```
+
+## Supported Printer Models
+- D11
+- D110
+- B21
+- B1
+- B18
+
+## Key Modules
+
+### UI Components
+- `NiimPrintX/ui/main.py` - Main application window
+- `NiimPrintX/ui/widget/TextTab.py` - Text input tab
+- `NiimPrintX/ui/widget/TextOperation.py` - Text rendering operations
+- `NiimPrintX/ui/widget/PrintOption.py` - Print settings
+
+### CLI Components
+- `NiimPrintX/cli/__main__.py` - CLI entry point
+
+### Printer Interface
+- `NiimPrintX/nimmy/printer.py` - Printer communication
+
+## Testing Multi-line Text Feature
+
+```python
+import tkinter as tk
+from NiimPrintX.ui.main import LabelPrinterApp
+
+# Create app
+app = LabelPrinterApp()
+app.load_resources()
+
+# Access text tab
+text_tab = app.text_tab
+
+# Test multi-line input
+multi_line_text = "Line 1\nLine 2\nLine 3"
+text_tab.content_entry.delete("1.0", tk.END)
+text_tab.content_entry.insert("1.0", multi_line_text)
+
+# Add to canvas
+text_tab.add_button.invoke()
+
+# Verify
+assert len(app.app_config.text_items) > 0
+```
+
+## Common Issues
+
+### Missing tkinter
+```bash
+sudo apt-get install python3-tk  # Linux
+# tkinter is included with Python on macOS/Windows
+```
+
+### Missing ImageMagick
+```bash
+# Linux
+sudo apt-get install imagemagick libmagickwand-dev
+
+# macOS
+brew install imagemagick
+```
+
+### Display not available (for testing)
+```bash
+# Use Xvfb for headless testing
+Xvfb :99 -screen 0 1024x768x24 &
+export DISPLAY=:99
+```
+
+## CI/CD Integration
+
+The project uses GitHub Actions with the following workflows:
+- `python-app.yml` - Linting and testing
+- `tag.yaml` - Release builds
+- Build workflows for Linux, macOS, and Windows
+
+See `.github/workflows/` for configuration details.
