# HOLE Fonts Project - Current Status

**Last Updated:** 2025-12-29
**Current Version:** v0.2.0 (Ready for Release)
**Status:** Production-ready, tested on 11,047 font collection

## Project Overview

HOLE Fonts is a professional font library management system for the HOLE Foundation's extensive font collection. The system provides font conversion, metadata extraction, duplicate detection, search capabilities, and Adobe Typekit enrichment.

### Primary Goals

1. **Font Conversion** - Convert fonts between TTF, OTF, and WOFF2 formats
2. **Metadata Intelligence** - Extract comprehensive font metadata using FontTools
3. **Duplicate Detection** - Identify duplicate fonts with strict confidence scoring
4. **Search & Filter** - Find fonts by family, weight, width, italic, variable axes, designer, foundry
5. **Typekit Enrichment** - Optional enhancement with Adobe Typekit API data

- **Package Manager:** uv
- **Core Libraries:**
  - FontTools 4.61.1 (font manipulation)
  - Click (CLI framework)
  - Rich (terminal UI)

## Recent Accomplishments (v0.2.0)

### 1. Metadata Extraction System
- Built FontAnalyzer class using FontTools
- Extracts: family name, PostScript name, weight (100-900), width, italic, variable axes
- SHA256 hashing for duplicate detection
- Glyph count analysis

### 2. Duplicate Detection (Fixed with Strict Matching)
- **Critical fix:** User reported 1,860 false positives
- **Problem:** Heavy Italic was matching Regular Italic (different weights)
- **Solution:** Implemented strict rules requiring EXACT matches on:
  - Weight (must be identical)
  - Italic status (must be identical)
  - Width (must be identical)
  - Monotype unique IDs (6-digit numbers)
  - Name similarity raised to 95% threshold
- **Result:** 1,860 false positives → 101 real duplicates (8.8 MB savings)

### 3. Search System
- Search by: family, weight range, italic, width, variable fonts, axes, format
- Classification inference from font names
- Designer/foundry search (requires Typekit enrichment)

### 4. Typekit API Integration
- Rate-limited API client with LRU caching
- Font name normalization for better matching
- Batch enrichment with progress callbacks
- API Key: `459aa874c56344b9c2f44b3a5edde401dc918fca`

### 5. Full Library Scan Completed
- **Scanned:** 11,047 fonts from RAID drive
- **Found:** 324 variable fonts, 1,651 font families
- **Database:** `HOLE-Fonts-RAID-Database.json` (8.1 MB)
- **Enriched:** 28 fonts with Typekit data
- **Performance:** ~10-20 fonts/second on local storage

## Key Commands

### Installation
```bash
uv sync                    # Install dependencies
uv sync --reinstall-package hole-fonts  # Reinstall package
```

### Scanning
```bash
# Scan directory and create metadata database
uv run python -m hole_fonts.cli scan <directory> --output database.json

# Example: Scan RAID drive fonts
uv run python -m hole_fonts.cli scan "/Volumes/HOLE-RAID-DRIVE/HOLE-Assets/HOLE-Fonts" --output HOLE-Fonts-RAID-Database.json
```

### Duplicate Detection
```bash
# Find duplicates in database
uv run python -m hole_fonts.cli dedup database.json --min-confidence 0.60
```

### Search
```bash
# Search for fonts
uv run python -m hole_fonts.cli search database.json --family "Helvetica" --weight-min 700

# Find all variable fonts
uv run python -m hole_fonts.cli search database.json --variable

# Find sans-serif fonts (requires Typekit enrichment)
uv run python -m hole_fonts.cli search database.json --classification "sans-serif"
```

### Typekit Enrichment
```bash
# Enrich database with Typekit data (use custom script due to CLI bug)
uv run python enrich_fonts.py
```

## Important Files Created

### Databases
- `HOLE-Fonts-RAID-Database.json` - 11,047 fonts, full metadata
- `HOLE-Fonts-RAID-Enriched.json` - Same as above + Typekit enrichment (28 fonts)
- `test-scan.json` - Test scan of Input/ directory (4,241 fonts)

### Reports
- `dedup-report.json` - Duplicate detection results (101 duplicates, 8.8 MB savings)

### Scripts
- `enrich_fonts.py` - Typekit enrichment script (workaround for CLI bug)
- `organize-by-format.py` - Reorganize fonts into TTF/OTF/WOFF2 folders
- `export-and-organize.sh` - Combined export + organize workflow
- `process-all-fonts.sh` - Batch process font families

---

## Critical Learnings

### 1. Duplicate Detection Must Be Strict
**Never match fonts as duplicates unless:**
- Weight matches EXACTLY (400 ≠ 700)
- Italic status matches EXACTLY (italic ≠ regular)
- Width matches EXACTLY (condensed ≠ extended)
- Monotype unique IDs match (if present)
- Name similarity >95%

**Example of incorrect match that was fixed:**
- ❌ UniversNext731BasicHeavyItalic-680379 vs UniversNext431BasicItalic-680373
- Different weights (900 vs 400), different IDs (680379 vs 680373)

### 2. iCloud Font Storage Is Too Slow
- Scanning 32,796 fonts from iCloud path was stuck on I/O
- Local RAID drive: 11,047 fonts in ~5 minutes
- **Recommendation:** Keep working fonts on local/RAID storage

### 3. FontTools vs Typekit
- **FontTools:** 100% coverage, extracts directly from font files
- **Typekit API:** Limited coverage (~0.25%), only commercial fonts in their database
- **Best approach:** Use FontTools for metadata, Typekit as optional enrichment

{
  "filename": "HelveticaBold-123456.ttf",
  "file_hash": "sha256...",
  "postscript_name": "Helvetica-Bold",
  "family_name": "Helvetica",
  "weight": 700,
  "width": "normal",
  "italic": false,
  "is_variable": false,
  "axes": null,
  "glyph_count": 516,
  "format": "ttf",
  "file_size": 65536
}
```

### Typekit Enrichment Structure
```json
{
  "file_hash": {
    "typekit_id": "gkmg",
    "foundry": "Monotype",
    "designer": "Max Miedinger",
    "classifications": ["sans-serif", "neo-grotesque"],
    "typekit_slug": "helvetica"
  }
}
```

- AgencyFB Cond (condensed)
- AgencyFB Ext (extended)
- AgencyFB Wide (wide)

Each available in TTF, OTF, WOFF2

## Next Steps (Ready for v0.2.0 Release)

1. **Update version in pyproject.toml** to 0.2.0
2. **Build Python wheel:** `uv build`
3. **Create git commit** with v0.2.0 changes
4. **Tag release:** `git tag v0.2.0`
5. **Push to GitHub:** `git push && git push --tags`
6. **Create GitHub release** with:
   - Changelog
   - Python wheel artifact
   - Database samples
   - Documentation

### Optional: Binary Distribution
- Build standalone executable with PyInstaller
- Platform-specific builds (macOS, Linux, Windows)
- Include in GitHub release assets

---

## Configuration

### Typekit API
- **API Key:** `459aa874c56344b9c2f44b3a5edde401dc918fca`
- **Rate Limit:** 0.5 seconds between requests
- **Caching:** LRU cache (1000 entries)

### Package Settings
```toml
[project]
name = "hole-fonts"
version = "0.2.0"
requires-python = ">=3.12"
```

---

## Known Issues

1. **CLI enrich command bug** - Parameter parsing issue, use `enrich_fonts.py` script instead
2. **WOFF2 conversion failure** - 1 font fails (SilkRemingtonProFourteen), TTF/OTF available
3. **iCloud sync slowness** - Use local/RAID storage for scanning

---

## Git Repository

## Quick Reference

### Search Example
```python
import json
with open('HOLE-Fonts-RAID-Database.json') as f:
    db = json.load(f)

# Find all AgencyFB Regular weight WOFF2 fonts
results = [f for f in db['fonts']
           if 'agencyfb' in (f.get('family_name') or '').lower()
           and f.get('weight') == 400
           and f.get('format') == 'woff2']
```

### Rebuild Package
```bash
uv sync --reinstall-package hole-fonts
```

### Run Tests
```bash
uv run hole-fonts scan Input/ --output test.json
```
