# FontSearch

A cross-platform Python library for discovering and analyzing system fonts with minimal dependencies.

## Features

- **Cross-platform**: Works on Windows, macOS, and Linux
- **Minimal dependencies**: Core functionality uses only Python standard library
- **Advanced filtering**: Filter by text support, font types, random sampling
- **Font analysis**: Optional advanced features with fonttools
- **CLI interface**: Command-line tool for quick font discovery
- **GUI interface**: Graphical font viewer with advanced features
- **Internationalization**: Support for 10 major languages (5.2B+ speakers)
- **Ligature controls**: OpenType ligature support (contextual & historical) with Pillow
- **Easy integration**: Simple API for use in other projects
- **Clean output**: Suppresses fonttools warnings for professional usage

## Installation

### Basic installation (no dependencies)
```bash
pip install fontsearch
```

### Full installation (with fonttools for advanced features)
```bash
pip install fontsearch[full]
```

### GUI installation (with GUI support and ligatures)
```bash
pip install fontsearch[gui]
```

### Complete installation (all features including ligatures)
```bash
pip install fontsearch[all]
```

## Quick Start

### Python API

```python
import fontsearch

# Get all installed fonts
fonts = fontsearch.get_fonts()
print(f"Found {len(fonts)} fonts")

# Get detailed font information
font_info = fontsearch.find_fonts()
for font in font_info[:5]:
    print(f"{font.name} ({font.font_type.name if font.font_type else 'Unknown'})")
    print(f"  Path: {font.path}")

# Find fonts supporting specific text (requires fonttools)
emoji_fonts = fontsearch.find_fonts(text="🌷😀")
print(f"Fonts supporting emojis: {len(emoji_fonts)}")

# Filter by font type
from fontsearch import FontType
ttf_fonts = fontsearch.find_fonts(types=[FontType.TTF])
print(f"TrueType fonts: {len(ttf_fonts)}")

# Get random sample
random_fonts = fontsearch.find_fonts(random_order=True, max_results=10)
print("10 random fonts:")
for font in random_fonts:
    print(f"  {font.name}")

# Advanced filtering
german_fonts = fontsearch.find_fonts(
    text="äöü ß",
    types=[FontType.TTF, FontType.OTF],
    max_results=20
)
```

### GUI Widget Component

FontSearch includes a reusable tkinter widget that can be embedded in other applications:

```python
import tkinter as tk
from fontsearch import FontPickerWidget

def on_font_selected(font_name):
    print(f"Selected font: {font_name}")

root = tk.Tk()
root.title("My App with FontSearch")

# Embed FontSearch widget
font_picker = FontPickerWidget(
    root,
    width=600,
    height=400,
    on_font_selected=on_font_selected,
    show_language_selector=True,
    show_ligature_controls=True
)
font_picker.pack(fill=tk.BOTH, expand=True, padx=10, pady=10)

root.mainloop()
```

**Widget Features:**
- 🎨 **Embeddable component** for any tkinter application
- 🌍 **10 language support** with automatic detection
- 🔤 **Ligature controls** for advanced typography
- 🎯 **Font selection callbacks** for integration
- ⚙️ **Configurable UI elements** (show/hide controls)
- 📱 **Responsive design** with proper scaling

See `WIDGET_INTEGRATION_GUIDE.md` for complete integration examples.

### Command Line Interface

```bash
# List all fonts
fontsearch

# Launch graphical user interface
fontsearch --gui

# Launch advanced GUI with SVG support
fontsearch --gui-advanced

# Launch internationalized GUI (10 languages)
fontsearch --gui-i18n

# Find fonts supporting emojis
fontsearch --text "🌷😀"

# Only TrueType and OpenType fonts
fontsearch --types TTF,OTF

# 10 random fonts with paths
fontsearch --random --max 10 --paths

# German character support
fontsearch --text "äöü ß" --paths
```

## API Reference

### Core Functions

#### `get_fonts() -> List[str]`
Returns a list of all installed font names.

#### `get_font_files() -> Dict[str, Path]`
Returns a dictionary mapping font names to their file paths.

#### `find_fonts(text=None, types=None, random_order=False, max_results=None) -> List[FontInfo]`
Advanced font search with filtering options.

**Parameters:**
- `text` (str, optional): Filter fonts that support these characters. Requires fonttools.
- `types` (List[FontType], optional): Filter by font file types (TTF, OTF, etc.).
- `random_order` (bool): Return results in random order.
- `max_results` (int, optional): Maximum number of results to return.

**Returns:** List of `FontInfo` objects.

#### `check_font_supports_text(font_path: Path, text: str) -> bool`
Check if a font file supports all characters in the given text. Requires fonttools.

### Data Classes

#### `FontInfo`
```python
@dataclass
class FontInfo:
    name: str              # Font display name
    path: Path             # Path to font file
    font_type: FontType    # Font file type (TTF, OTF, etc.)
```

#### `FontType` (Enum)
- `FontType.TTF` - TrueType fonts (.ttf)
- `FontType.OTF` - OpenType fonts (.otf)
- `FontType.TTC` - TrueType collections (.ttc)
- `FontType.WOFF` - Web fonts (.woff)
- `FontType.WOFF2` - Web fonts v2 (.woff2)

## Examples

### Find fonts for multilingual text
```python
import fontsearch

# Find fonts supporting multiple languages
multilingual_text = "Hello 你好 مرحبا Здравствуйте"
fonts = fontsearch.find_fonts(text=multilingual_text)

print(f"Fonts supporting multilingual text: {len(fonts)}")
for font in fonts:
    print(f"  {font.name}")
```

### Analyze font distribution by type
```python
import fontsearch
from collections import Counter

fonts = fontsearch.find_fonts()
type_counts = Counter(font.font_type.name if font.font_type else 'Unknown' 
                     for font in fonts)

print("Font distribution by type:")
for font_type, count in type_counts.most_common():
    print(f"  {font_type}: {count}")
```

### Random font sampler
```python
import fontsearch

def get_random_font_sample(n=5):
    """Get a random sample of fonts."""
    return fontsearch.find_fonts(random_order=True, max_results=n)

# Get 5 random fonts
sample = get_random_font_sample(5)
for font in sample:
    print(f"{font.name} - {font.path}")
```

### GUI Integration
```python
import fontsearch

# Perfect for GUI font selectors
all_fonts = fontsearch.find_fonts()
font_names = [font.name for font in all_fonts]

# Real-time filtering for search-as-you-type
def filter_fonts(search_text):
    return fontsearch.find_fonts(text=search_text, max_results=20)

# Font categorization
ttf_fonts = fontsearch.find_fonts(types=[fontsearch.FontType.TTF])
```

### GUI Interface

FontSearch includes a graphical user interface for interactive font browsing:

```bash
# Launch GUI from command line
fontsearch --gui

# Or run directly
python -m fontsearch.gui
```

**GUI Features:**
- Interactive font browsing with pagination
- Real-time text filtering
- Font type filtering
- Ligature controls (contextual and historical)
- Font preview with custom text
- Professional interface with clean output

## Dependencies

### Core (no dependencies)
The core functionality works with Python standard library only:
- Font discovery on Windows (via registry)
- Font discovery on macOS (via system directories)  
- Font discovery on Linux (via fontconfig or directory scanning)
- Basic filtering and sorting

### Optional (fonttools)
Advanced features require fonttools:
```bash
pip install fonttools
```

Features enabled with fonttools:
- Text support checking (`check_font_supports_text`)
- Character coverage analysis
- Advanced font metadata reading

## Platform Support

- **Windows**: Uses Windows Registry and system font directories
- **macOS**: Uses system font directories and system_profiler
- **Linux**: Uses fontconfig (fc-list) with fallback to directory scanning
